Genotype and Nitrogen fertilizer influence on Grain yield and protein content of wheat(Triticum aestivum L.)
The grain yield of wheat in Lesotho is low because of poor soil fertility, and the wheat is regarded by the millers to be of poor quality and therefore of less value. A field study was therefore conducted at three sites in Lesotho( Maseru, Leribe and Mafeteng) to evaluate the influence of genotype …

Plant growth regulators and biostimulants for use in varying management systems to improve corn grain yield
… to optimize their return on investment and crop yield potential. The objective of this study was to evaluate the responses of corn (Zea mays L.) grain yield to in-furrow and foliar applications of PGRs and biostimulants, and to determine if PGRs and biostimulants impact yield differently under …

The effect of rate and time of application of Azolla on rice(Oryza Sativa L.)Grain yield
… pinnata at 4, 8 and 12 t/ha were used to check yield performance compared to urea at 60 kgN/ha and a control (no azolla, no urea). Four times of application i.e during transplanting (DT), DT and 42 days after transplanting (DAT); DT and 56 DAT; DT and 70 DAT were studied. The experiment was …

The influence of cultivar and environment on the relationship between flour protein content and grain yield in wheat
… 1982/83 growing seasons. Genetic variability in grain yield and flour protein content (protein content) of wheat (Triticum aestivum L.) was evaluated. The influence of several agronomic practices on the yield and protein relationship was studied. The cultivar x environment interactions for grain …
