Maize seed aid and seed systems development: Opportunities for synergies in Uganda

Jason Donovan Rachel Voss Pieter Rutsaert (2024, [Artículo])

In the name of food security, governments and NGOs purchase large volumes of maize seed in non-relief situations to provide at reduced or no cost to producers. At the same time, efforts to build formal maize seed systems have been frustrated by slow turnover rates – the dominance of older seed products in the market over newer, higher performing ones. Under certain conditions, governments and NGO seed aid purchases can support formal seed systems development in three ways: i) support increased producer awareness of new products, ii) support local private seed industry development, and iii) advance equity goals by targeting aid to the most vulnerable of producers who lack the capacity to purchase seeds. This study explores the objectives and activities of seed aid programmes in Uganda and their interactions with the maize seed sector. We draw insights from interviews with representatives of seed companies, NGOs and government agencies, as well as focus group discussions with producers. The findings indicated that seed aid programme objectives are largely disconnected from broader seed systems development goals. There is little evidence of public-private collaboration in design of these programmes. Better designed programs have the potential to align with varietal turnover objectives, commercial sector development and targeting of underserved markets could promote equity and ‘crowd in’ demand.

Can I speak to the manager? The gender dynamics of decision-making in Kenyan maize plots

Rachel Voss Zachary Gitonga Jason Donovan Mariana Garcia-Medina Pauline Muindi (2023, [Artículo])

Gender and social inclusion efforts in agricultural development are focused on making uptake of agricultural technologies more equitable. Yet research looking at how gender relations influence technology uptake often assumes that men and women within a household make farm management decisions as individuals. Relatively little is understood about the dynamics of agricultural decision-making within dual-adult households where individuals’ management choices are likely influenced by others in the household. This study used vignettes to examine decision-making related to maize plot management in 698 dual-adult households in rural Kenya. The results indicated a high degree of joint management of maize plots (55%), although some management decisions—notably those related to purchased inputs—were slightly more likely to be controlled by men, while other decisions—including those related to hiring of labor and maize end uses—were more likely to be made by women. The prevalence of joint decision-making underscores the importance of ensuring that both men’s and women’s priorities and needs are reflected in design and marketing of interventions to support maize production, including those related to seed systems, farmer capacity building, and input delivery.

Mejoramiento del grado de uso del nitrógeno en maíz mediante técnicas parcelarias de riego por superficie

Improving the usage level of nitrogen in maize, through surface irrigation plot techniques

JAIME MACIAS CERVANTES JESUS DEL ROSARIO RUELAS ISLAS PABLO PRECIADO RANGEL WALDO OJEDA BUSTAMANTE MARCO ANTONIO INZUNZA IBARRA JOSE ALFREDO SAMANIEGO GAXIOLA (2015, [Artículo])

El maíz es uno de los principales cultivos sembrados en el estado de Sinaloa; sin embargo, en esta región la aplicación de riegos se realiza sin considerar las características físicas del suelo incrementando las pérdidas de agua y fertilizantes. Es importante desarrollar tecnologías que permitan optimizar el uso de insumos (agua, fertilizantes, pesticidas) incrementando el potencial productivo de los cultivos y reduciendo los costos de producción, por tal motivo, se desarrollaron una serie de experimentos durante los ciclos otoño-invierno 2006-2007 y 2011-2012 en el norte de Sinaloa, México, con el propósito de conocer el efecto del riego por gravedad por diferentes técnicas en la eficiencia de uso del nitrógeno (N) en el cultivo de maíz.

Relación entre Bactericera cockerelli y presencia de Candidatus Liberibacter psyllaurous en lotes comerciales de papa

OSWALDO ANGEL RUBIO COVARRUBIAS ISIDRO HUMBERTO ALMEYDA LEON MATEO ARMANDO CADENA HINOJOSA RENE LOBATO SANCHEZ (2011, [Artículo])

La brotación anormal de los tubérculos (sin brotes o brotes ahilados) y el pardeamiento interno de los tubérculos, son síntomas de una enfermedad que está afectando la producción de papa en México, en el suroeste de Estados Unidos y América central. Esta enfermedad ha sido asociada con el psilido de la papa Bactericera cockerelli Sulc. Con el objetivo de dilucidar las causas de esta enfermedad, en 2007 se llevó a cabo un muestreo en 11 lotes comerciales de papa localizados en un transecto altitudinal entre 2 600 y 3 500 m en la región productora de papa de Toluca. La población de B. cockerelli fue determinada mediante muestreos semanales de los insectos adultos atrapados en trampas amarillas pegajosas. Al final del periodo de crecimiento del cultivo, los tubérculos producidos en cada lote fueron muestreados y almacenados por 6 meses. Después de este tiempo, se determinó el porcentaje de tubérculos con brotación anormal y se hicieron análisis con PCR para determinar la presencia de Candidatus Liberibacter psyllaurous y de fitoplasmas en los tubérculos.
