Background: Potassium is a major nutrient needed by the crops including tuber crops. It essential for initiation and bulking process. Varietal differences in potassium uptake utilization many were reported. As varieties of sweet potato are released so far, studies on understanding variations accumulation its influence yield essential. Methods: Field experiments conducted during kharif rabi seas...

Four experiments were carried out at the São Paulo State University, Brazil, with the aim of determining the agronomic viability of intercropping tomato and lettuce, under greenhouse conditions. The studied intercropping systems were established by transplanting lettuce at 0, 10, 20 and 30 days after transplanting (DAT) tomato and by transplanting tomato at 0, 10, 20 and 30 DAT lettuce. Intercr...

Abstract Smallholder farmers in Ethiopia are involved multiple seed sources to access bread wheat seed. The present study was conducted Baso Liben district, northwest Ethiopia, with the objectives of identifying existing sources, factors affecting use improved seed, and assessing practitioners’ (farmers experts) suggestions improve sources. Both quantitative qualitative data were collected from...

Three factors that directly affect the water inputs in cropping systems are root architecture, length of the growing season, and stomatal conductance to water vapor (). Deeper-rooted cultivars will perform better under water-limited conditions because they can access water stored deeper in the soil profile. Reduced limits transpiration rate () and thus throughout the vegetative phase conserves ...

Maize is priority crop to farmers because it a stable food in many rural communities of southern region. It widely grown the various parts region from lowland mid-highlands. On other hand, moisture stress one most critical production constraints maize low intermediate agro-ecology. Thus, developing varieties tolerant paramount important order sustain areas. In this content, field experiments we...

genotype×environment interactions (geis) can affect breeding programs because they often complicate the evaluation and selection of superior genotypes. this drawback can be reduced by gaining insights into gei processes and genotype adaptation. the objectives of this research were to evaluate: (1) the yield stability of promising wheat lines across locations and (2) the relationship among the t...

We monitored soil respiration (Rs), soil temperature (T) and volumetric water content (VWC%) over four years in one typical conventional and four alternative cropping systems to understand Rs in different cropping systems with their respective management practices and environmental conditions. The control was conventional double-cropping system (winter wheat and summer maize in one year--Con.W/...

A longitudinal cross-over feeding design was used to investigate the relationship of dietary lipid composition to the membrane lipid environment and activity of mitochondrial ATPase in vivo. Rats were fed a polyunsaturated fatty-acid-rich oil (soya-bean oil) for 12 days, crossed-over to a monounsaturated fatty-acid-rich oil (rapeseed oil) for the next 11 days, then returned to soya-bean oil for...

Four million hectares of wheat are planted after cotton and rice in Pakistan. Little research has been done on the aronomy of wheat following these crops on a cropping pattern basis. Both of these crops delay wheat planting, and it is estimated that 40–50 kg of wheat grain is lost for every day that planting is delayed past 20 November. Current recommendations for land preparation, fertilizer u...

One of the principal aims of alternative cropping systems is to minimize excessive loss of N while maximizing N use efficiency and meeting crop N requirements. Many such cropping systems substitute intensive application of synthetic fertilizer with organic inputs, such as N2-fixing legumes. The effectiveness of legume residues as a N source for subsequent crops depends heavily on temporal N rel...
