Modeling the growth, yield and N dynamics of wheat for decoding the tillage and nitrogen nexus in 8-years long-term conservation agriculture based maize-wheat system

C.M. Parihar Dipaka Ranjan Sena Prakash Chand Ghasal Shankar Lal Jat Yashpal Singh Saharawat Mahesh Gathala Upendra Singh Hari Sankar Nayak (2024, [Artículo])

Context: Agricultural field experiments are costly and time-consuming, and their site-specific nature limits their ability to capture spatial and temporal variability. This hinders the transfer of crop management information across different locations, impeding effective agricultural decision-making. Further, accurate estimates of the benefits and risks of alternative crop and nutrient management options are crucial for effective decision-making in agriculture. Objective: The objective of this study was to utilize the Crop Environment Resource Synthesis CERES-Wheat model to simulate crop growth, yield, and nitrogen dynamics in a long-term conservation agriculture (CA) based wheat system. The study aimed to calibrate the model using data from a field experiment conducted during the 2019-20-2020-21 growing seasons and evaluation it with independent data from the year 2021–22. Method: Crop simulation models, such as the Crop Environment Resource Synthesis CERES-Wheat (DSSAT v 4.8), may provide valuable insights into crop growth and nitrogen dynamics, enabling decision makers to understand and manage production risk more effectively. Therefore, the present study employed the CERES-Wheat (DSSAT v 4.8) model and calibrated it using field data, including plant phenological phases, leaf area index, aboveground biomass, and grain yield from the 2019-20-2020-21 growing seasons. An independent dataset from the year 2021–22 was used for model evaluation. The model was used to investigate the relationship between growing degree days (GDD), temperature, nitrate and ammonical concentration in soil, and nitrogen uptake by the crop. Additionally, the study explored the impact of contrasting tillage practices and fertilizer nitrogen management options on wheat yields. The experimental site is situated at ICAR-Indian Agricultural Research Institute (IARI), New Delhi, representing Indian Trans-Gangetic Plains Zone (28o 40’N latitude, 77o 11’E longitude and an altitude of 228 m above sea level). The treatments consist of four nitrogen management options, viz., N0 (zero nitrogen), N150 (150 kg N ha−1 through urea), GS (Green seeker based urea application) and USG (urea super granules @150 kg N ha−1) in two contrasting tillage systems, i.e., CA-based zero tillage (ZT) and conventional tillage (CT). Result: The outcomes exhibited favorable agreement between the model’s simulations and the observed data for crop phenology (With less than 2 days variation in 50% onset of flowering), grain and biomass yield (Root mean square error; RMSE 336 kg ha−1 and 649 kg ha−1, respectively), and leaf area index (LAI) (RMSE 0.28 & normalized RMSE; nRMSE 6.69%). The model effectively captured the nitrate-N (NO3−-N) dynamics in the soil profile, exhibiting a remarkable concordance with observed data, as evident from its low RMSE = 12.39 kg ha−1 and nRMSE = 13.69%. Moreover, as it successfully simulated the N balance in the production system, the nitrate leaching and ammonia volatilization pattern as described by the model are highly useful to understand these critical phenomena under both conventional tillage (CT) and CA-based Zero Tillage (ZT) treatments. Conclusion: The study concludes that the DSSAT-CERES-Wheat model has significant potential to assess the impacts of tillage and nitrogen management practices on crop growth, yield, and soil nitrogen dynamics in the western Indo-Gangetic Plains (IGP) region. By providing reliable forecasts within the growing season, this modeling approach can facilitate better planning and more efficient resource management. Future implications: The successful implementation of the DSSAT-CERES-Wheat model in this study highlights its applicability in assessing crop performance and soil dynamics. Future research should focus on expanding the model’s capabilities by reducing its sensitivity to initial soil nitrogen levels to refine its predictions further. Moreover, the model’s integration with decision support systems and real-time data can enhance its usefulness in aiding agricultural decision-making and supporting sustainable crop management practices.

Rainfall water quality at Atlixco, Puebla

Margarita Teutli Andrés Armando Sánchez Erendira Moreno Gutierrez (2021, [Artículo, Artículo])

This work reports the follow up of rainfall water quality at Atlixco, Puebla during the 2018 season. The main objective of this work was to evaluate how height and pollutants define the quality of water precipitated. Samples were collected at the roof of a house in Atlixco center, and others at the roof of a convent located at the San Miguel Hill, this represents a 44 m difference in height. Chemical composition was analyzed for 19 physicochemical parameters using gravimetric and spectrophotometric techniques. Obtained results were compared with drinking water standards finding that Pb and Cd contents are exceeded. Also, it was found a strong contribution of terrestrial sources since the marine rates are above unit, as well as excess concentrations whose values go from negative to positive. Finally, Pearson correlation was obtained finding that most of chemical parameters correlations are in disagreement for both sites, fact which confirms that ionic content is strongly influenced by anthropogenic sources.

Uso del cártamo (Carthamus tinctorius L.) como ingrediente en alimentos para juveniles del camarón Litopenaeus vannamei

ALFONSO GALICIA GONZALEZ (2009, [Tesis de doctorado])

Debido a los altos costos e incertidumbre en el abasto de la harina de pescado y pasta de soya, en los últimos años se han buscado alternativas que puedan sustituirlos sin tener un efecto negativo en el crecimiento de los camarones en el cultivo. En el presente trabajo se realizó un estudio para evaluar el valor nutricional del cártamo (Carthamus tinctorius) como fuente proteica en alimentos para juveniles de camarón blanco del Pacífico Litopenaeus vannamei. El primer capítulo comprende el estudio de la caracterización de tres productos de cártamo (HIC; Harina Integral de Cártamo, PCB; Pasta de cártamo baja en proteína y PCA; Pasta de cártamo alta en proteína) en base a su composición de nutrientes y algunos factores antinutricionales (hemaglutininas, saponinas, actividad uréasica, aflatoxinas e inhibidor de tripsina). Los productos de cártamo tuvieron un contenido de proteína entre 20.6 y 36.8%. La harina integral fue la que presentó el mayor nivel de extracto etéreo 31%, mientras que las pastas tuvieron un nivel bajo (1.8-1.0%). El contenido de fibra en el cártamo fue alto (17-23%). Los aminoácidos más abundantes en los productos de cártamo fueron el ácido aspártico y glutámico, en contraste los menos abundantes fueron lisina y metionina. Los ácidos grasos más abundantes fueron el ácido oleico, el linoleico, el palmítico y el estéarico. El contenido de calcio de los productos de cártamo varió de 0.25 a 0.42%, mientras que el contenido de fósforo varió del 0.23 a 0.25%. No se encontraron los factores antinutricionales buscados, a excepción del inhibidor de tripsina que tuvo valores bajos (7.56 UTI/mg de muestra). No se encontraron diferencias significativas en los coeficientes de utilización digestiva aparente (CUDA) de materia seca y carbohidratos de los productos de cártamo; sin embargo, sí se encontraron diferencias en los CUDA de proteína, lípidos (CUDAl) y de energía digestible (CUDAe). La actividad de las enzimas digestivas de camarones que fueron alimentados con productos de cártamo mostró un incremento en proteinasas generales y quimotripsina. La atractabilidad y el consumo de los alimentos con un 30% de inclusión de los productos de cártamo se vieron afectadas negativamente en los camarones [...]

In recent years, alternatives to fish and soybean meals in aquacultural feeds that do not have negative effects on growth of cultivated shrimp have been intensively studied in an effort to reduce the high costs and uncertainty in supplies. In this study, the nutritional value of safflower (Carthamus tinctorius) meal as a protein source in diets for juveniles Pacific whiteleg shrimp (Litopenaeus vannamei) was investigated. Initially, characterization of three safflower meals (i.e. WSM; whole safflower meal, LPSM; low-protein safflower meal and HPSM; high-protein safflower meal), focusing on chemical composition and antinutritional factors (hemaglutinine, saponine, ureasic activity, aflatoxin, and trypsin inhibitor) was conducted. Protein content ranged from 20.6 to 36.8%. Whole safflower meal contained the highest level of lipids (31%); lipids in the other safflower meals were as low as 1.0–1.8%. Fiber content was high (17–23%). The most abundant amino acids were aspartic and glutamic acids and lysine and methionine were less abundant. Oleic, linoleic, palmitic, and stearic fatty acids were present in greatest amounts. Calcium content ranged from 0.25–0.42% and phosphorus content ranged from 0.23–0.25%. Anti-nutritional factors were not found in the analyses, except for trypsin inhibitor, with values as low as 7.56 UTI mg–1 per sample. No significant differences between the apparent digestibility coefficients (ADC) for dry matter and carbohydrates in safflower meals were detected; however, protein ADC, lipid ADC, and energy ADC were different. Total proteinase and chymotrypsin increased significantly in diets where safflower meals were included. Atractability and consumption of feed with 30% safflower meals appeared to have negative effects on the juveniles [...]

Effect of rosemary powder (Rosmarinus officinalis) on growth, enzyme activity, and proximal composition of juvenile stripped bass (Morone saxatilis)

Erick Adolfo Barrios García (2023, [Tesis de maestría])

La acuicultura intensiva ha experimentado un rápido crecimiento en las últimas décadas. Sin embargo, la intensificación de los cultivos acuícolas ha ocasionado problemas como el estrés en los organismos, desarrollo de enfermedades y un menor crecimiento. Se ha explorado el uso de plantas aromáticas como el romero (Rosmarinus officinalis) por su efecto como antibiótico, antiestresante y estimulante de la secreción de enzimas digestivas y el crecimiento. El objetivo de este estudio fue evaluar la adición de polvo de romero en la dieta de la lobina rayada (Morone saxatilis) y determinar su efecto en la supervivencia, crecimiento, actividad enzimática (tripsina, quimiotripsina, lipasa, amilasa y proteasas alcalinas totales -PAT-) y composición proximal. Se realizó un bioensayo durante 70 días en un sistema de recirculación de agua de mar donde se probaron cuatro dietas experimentales con diferentes cantidades de polvo de romero: control (TC), 2.5 (T2.5), 5 (T5) y 10 (T10) g kg-1 de dieta. Cada tratamiento se realizó por triplicado con 20 peces por réplica con un peso inicial de 19.59 ± 2.43 g. Las lobinas se alimentaron tres veces al día al 4% de su biomasa. Al final del bioensayo, el peso final de los peces en T5 y T10 fue significativamente menor en comparación con el TC. No se observaron diferencias significativas en parámetros de crecimiento y eficiencia alimenticia. El índice hepatosomático en el T10 fue significativamente mayor en relación con TC. En el intestino, la actividad de la tripsina fue significativamente menor en el T10 y las PAT en T2.5 y T10. En ciegos pilóricos, la actividad de la tripsina fue significativamente menor en el T10, la lipasa en T2.5, T5 y T10 y las PAT en T2.5 y T10. La inclusión de polvo de romero en la dieta de lobina en concentraciones de 5 y 10 g kg-1 disminuye el crecimiento y la actividad de tripsina, PAT y lipasa en intestino y ciegos pilóricos. Se requiere investigar la composición química del romero y su efecto como inhibidor de enzimas digestivas y modulador de la microbiota intestinal, además de incluir otros indicadores para conocer de forma integrada el desempeño fisiológico de la especie.

Intensive aquaculture has experienced a very rapid growth in recent years. However, the intensification of aquaculture has led to issues such as stress in organisms, the development of diseases, and reduced growth. The use of aromatic plants, such as rosemary (Rosmarinus officinalis), has been explored due to its antibiotic, anti-stress, and digestive enzyme secretion-stimulating effects, as well as its growth-promoting properties. The objective of this study was to evaluate the addition of rosemary powder to the diet of striped bass (Morone saxatilis) and determine its effect on survival, growth, enzyme activity (trypsin, chymotrypsin, lipase, amylase, and total alkaline proteases -PAT-), and proximate composition. A 70-day bioassay was conducted in a recirculating seawater system, testing four experimental diets with varying amounts of rosemary powder: control (TC), 2.5 (T2.5), 5 (T5), and 10 (T10) g kg-1 of diet. Each treatment was performed in triplicate with 20 fish per replicate, with an initial weight of 19.59 ± 2.43 g. The striped bass were fed three times a day at 4% of their biomass. At the end of the bioassay, the final weight of fish in T5 and T10 was significantly lower compared to TC. There were no significant differences in growth parameters and feed efficiency. The hepatosomatic index in T10 was significantly higher compared to TC. In the intestine, trypsin activity was significantly lower in T10, and PAT in T2.5 and T10. In the pyloric caeca, trypsin activity was significantly lower in T10, lipase in T2.5, T5, and T10, and PAT in T2.5 and T10. The inclusion of rosemary powder in striped bass diets at concentrations of 5 and 10 g kg-1 reduces growth and the activity of trypsin, PAT, and lipase in the intestine and pyloric caeca. Further research is imperative to delve into the intricate chemical composition of rosemary, explore its role as a potent digestive enzyme inhibitor, and its potential as a modulator of the intestinal microbiota. This endeavor should also encompass the incorporation of various additional indicators, aiming for a holistic grasp of the species' physiological performance.

Presencia de Perkinsus marinus en el ambiente y en los moluscos Anadara tuberculosa, Mytella strigata y Crassostrea corteziensis de la costa de Nayarit

Presence of Perkinsus marinus in the environment and in the mollusks Anadara tuberculosa, Mytella strigata and Crassostrea corteziensis from the coast of Nayarit

Naoki Abraham Kawamoto Camacho (2023, [Tesis de maestría])

El parásito Perkinsus marinus cuyo ciclo de vida le permite subsistir en el ambiente y cumplir su ciclo dentro del hospedero es el agente causal de la perkinsosis, letal para Crasssotrea virginica y enlistado por la Organización Mundial de Salud Animal (OMSA). El comercio de ostiones entre el Golfo de México y el Pacífico mexicano ha generado preocupaciones sanitarias al introducir estos moluscos en comunidades costeras del Pacífico. P. marinus formaría parte de la microbiota ambiental y estar en los moluscos bivalvos de estos ambientes. En el presente estudio se emplearon las técnicas PCR, qPCR, secuenciación de amplicones y de próxima generación, así como análisis de microbioma para determinar la presencia de P. marinus en el ambiente y en los moluscos Anadara tuberculosa, Mytella strigata y Crassostrea corteziensis que coexisten en el estero Pozo Chino, Nayarit. Además, se analizaron muestras embebidas en parafina de Tabasco, Veracruz (C. virginica), Nayarit y Sinaloa (C. corteziensis) para realizar comparaciones genotípicas. La prevalencia de infección mediante PCR fue de 86% en ostiones de la zona baja y media del estero, y de 66% en la zona alta, mientras que para M. strigata fue de 2.2% por qPCR. No se detectó a P. marinus en el ambiente ni en A. tuberculosa. La identidad del parásito fue de 86.1 al 100% mediante secuenciación dirigida. Los primers que amplifican productos de 130 pb fueron más eficaces. La no detección del parásito en el entorno se debe a su baja presencia, consecuencia de la baja salinidad, ausencia de infecciones graves y la falta de eventos inusuales de mortalidad, evitando la liberación masiva del parásito en el ambiente. Además, la baja detección en M. strigata y ausencia en A. tuberculosa puede relacionarse con su susceptibilidad. El análisis del microbioma eucariótico mostró a P. marinus como parte de la microbiota en C. corteziensis. En el ambiente los grupos más abundantes fueron copépodos, moluscos, poliquetos y diatomeas. Se requiere profundizar en su estudio en el ambiente y hospederos a lo largo del año para dimensionar mejor el riesgo sanitario que se enfrenta en una zona donde se ha establecido el parásito.

The parasite Perkinsus marinus, whose life cycle allows it to survive in the environment and complete its cycle within the host, is the causative agent of perkinsosis, lethal to Crassostrea virginica, and listed by the World Organisation for Animal Health (WOAH). The trade of oysters between the Gulf of Mexico and the Mexican Pacific coast has raised sanitary concerns by introducing these mollusks into coastal communities on the Pacific. In areas where detection has occurred, P. marinus would be part of the environmental microbiota (plankton/sediments) and in coexisting bivalve mollusks. In this study, PCR, Real-Time PCR (qPCR), amplicon sequencing and next-generation sequencing techniques, as well as microbiome analysis, were employed to determine the presence of P. marinus in the environment (plankton and sediments) and in the mollusks Anadara tuberculosa, Mytella strigata, and Crassostrea corteziensis coexisting in the Pozo Chino estuary, Nayarit. Paraffin-embedded samples from Tabasco, Veracruz (C. virginica), Nayarit, and Sinaloa (C. corteziensis) were also analyzed for genotypic comparisons. The infection prevalence through PCR was 86% in oysters from the lower and middle zones of the estuary and 66% in the upper zone, while for M. strigata, it was 2.2% by RT-PCR. P. marinus was not detected in the environment or in A. tuberculosa. Directed sequencing revealed a parasite identity of 86.1 to 100%. Primers amplifying 130 bp products were more effective. The lack of detection of the parasite in the environment is due to its low presence, resulting from low salinity, the absence of records of severe infections, and the lack of unusual mortality events, preventing massive release of the parasite into the environment. Additionally, the isolated detection in M. strigata and absence in A. tuberculosa may be related to their susceptibility. Analysis of eukaryotic microbiomes identified P. marinus as part of the microbiota in C. corteziensis. In the environment, the most abundant groups were copepods, mollusks, polychaetes, and diatoms. Further studies in the environment and hosts throughout the year are required to better understand the health risks in an area where the parasite has become established.

Mulch application as the overarching factor explaining increase in soil organic carbon stocks under conservation agriculture in two 8-year-old experiments in Zimbabwe

Regis Chikowo Christian Thierfelder Marc Corbeels (2024, [Artículo])

Conservation agriculture (CA), combining reduced or no tillage, permanent soil cover, and improved rotations, is often promoted as a climate-smart practice. However, our understanding of the impact of CA and its respective three principles on top- and subsoil organic carbon stocks in the low-input cropping systems of sub-Saharan Africa is rather limited. This study was conducted at two long-term experimental sites established in Zimbabwe in 2013. The soil types were abruptic Lixisols at Domboshava Training Centre (DTC) and xanthic Ferralsol at the University of Zimbabwe farm (UZF). The following six treatments, which were replicated four times, were investigated: conventional tillage (CT), conventional tillage with rotation (CTR), no tillage (NT), no tillage with mulch (NTM), no tillage with rotation (NTR), and no tillage with mulch and rotation (NTMR). Maize (Zea mays L.) was the main crop, and treatments with rotation included cowpea (Vigna unguiculata L. Walp.). The soil organic carbon (SOC) concentration and soil bulk density were determined for samples taken from depths of 0–5, 5–10, 10–15, 15–20, 20–30, 30–40, 40–50, 50–75 and 75–100 cm. Cumulative organic inputs to the soil were also estimated for all treatments. SOC stocks at equivalent soil mass were significantly (p<0.05) higher in the NTM, NTR and NTMR treatments compared with the NT and CT treatments in the top 5 cm and top 10 cm layers at UZF, while SOC stocks were only significantly higher in the NTM and NTMR treatments compared with the NT and CT treatments in the top 5 cm at DTC. NT alone had a slightly negative impact on the top SOC stocks. Cumulative SOC stocks were not significantly different between treatments when considering the whole 100 cm soil profile. Our results show the overarching role of crop residue mulching in CA cropping systems with respect to enhancing SOC stocks but also that this effect is limited to the topsoil. The highest cumulative organic carbon inputs to the soil were observed in NTM treatments at the two sites, and this could probably explain the positive effect on SOC stocks. Moreover, our results show that the combination of at least two CA principles including mulch is required to increase SOC stocks in these low-nitrogen-input cropping systems.

Shopping for Ecological Indices? On the Use of Incidence-Based Species Compositional Similarity Measures

"β-diversity has been under continuous debate, with a current need to better understand the way in which a new wave of measures work. We assessed the results of 12 incidence-based β-diversity indices. Our results of gradual species composition overlap between paired assemblages considering progressive differences in species richness show the following: (i) four indices (β-2, β-3, β-3.s, and βr) should be used cautiously given that results with no shared species retrieve results that could be misinterpreted; (ii) all measures conceived specifically as partitioned components of species compositional dissimilarities ought to be used as such and not as independent measures per se; (iii) the non-linear response of some indices to gradual species composition overlap should be interpreted carefully, and further analysis using their results as dependent variables should be performed cautiously; and (iv) two metrics (βsim and βsor) behave predictably and linearly to gradual species composition overlap. We encourage ecologists using measures of β-diversity to fully understand their mathematical nature and type of results under the scenario to be used in order to avoid inappropriate and misleading inferences."
