Abstract :

There have been numerous episodes of widespread adoption of improved seed and long-term achievements in the development of the maize seed industry in Sub-Saharan Africa. This summary takes a circumspect view of technical change in maize production. Adoption of improved seed has continued to rise gradually, now representing an estimated 44 percent of maize area in Eastern and Sout ...

Abstract :

Maize is divided into two types based on the starch composition of the endosperm in the seed, normal maize(or non-waxy maize) and waxy maize. In this study, genetic diversity and population structure were investigated among 80 waxy maize and normal inbred lines(40 waxy maize inbred lines and 40 normal maize inbred lines) using 50 SSR markers. A total of 242 alleles were identified at all the l ...

Abstract :

Field experiment was conducted on Takhli soil series (Typic Calciustolls) in a farmer field in Pakchong, Nakhon Ratchsima, to examine effects of intercropping groundnut and green manure legumes to maize on the yields of the intercrop maize, weed incidence and moisture status of the soil, as an effort to find green-manure legumes that could be intercropped to maize with minimum detrimental effe ...

Abstract :

In peasant subsistence agriculture use of appropriate cropping systems enable the farmers to use natural resources efficiently. Lack of appropriate cropping systems to suit maize production was identified as one of the major production constraints in the semi-arid areas of Ethiopia. To alleviate this problem the possibility of intercropping, relay cropping or alley cropping of maize with effic ...

Abstract :

Maize is the most important staple food in the Eastern Africa region and the most widely traded agricultural commodity. Therefore, the performance of grain markets has a significant impact on people's welfare, particularly the poor, and is critical to inducing pro-poor growth in Kenya, Tanzania, and Uganda, i.e. the countries under review in this report. Marketing costs at the bord ...

Abstract :

An experiment was conducted on four smallholder farms and on-station in the sub-humid zone of northeast Zimbabwe for 12 years to assess how the rotation of groundnut with NPK-fertilized and unfertilized maize affected the productivity and sustainability of this common smallholder cropping system. At the sandy-soil Domboshava station, maize grain yield declined over 12 years of continuous maize ...

Abstract :

Many farmers in central Mozambique intercrop maize with grain legumes as a means to improve food security and income. The objective of this study was to understand the farming system, and to evaluate the suitability of maize-legume intercropping to alleviate the biophysical and socio-economic constraints faced by smallholder farmers in Ruaca and Vunduzi villages, central Mozambique. To achieve ...

Abstract :

In Probolinggo area the predominant maize based "tegal" (dry land) cropping system is a rainy season maize monocrop followed by a maize/lab-lab bean intercrop. The maize in the maize/lab-lab intercrop is harvested shortly after the end of the reliable rainy season. The lab-lab bean grows through into the dry season, utilising residual soil moisture and the variable late rains. Pigeonpea could ...

Abstract :

The breeding programme on speciality maize with specific traits was established at the Maize Research Institute Zemun Polje, Belgrade - Zemun (Serbia) several decades ago. The initial material was collected, new methods applying to breeding of speciality maize, i.e. popping maize, sweet maize and white-seeded maize, were introduced. The aim was to enhance and improve variability of the initial ...
