Spatial variability of soil properties in field experiments introduces an extra source of variation and inflates experimental error, thus masking true treatment effects. Data from a field experiment i ... Read More
Soaking of cotton seeds prior to sowing and then rubbing in ash is a common practice to -facilitate germination under adverse soil conditions. But little has been reported of the effects of various pr ... Read More
The study was designed to evaluate the effects of tillage types including deep-ripping, conventional and zero tillage on compaction, using selected physical properties of agricultural soils.Particle s ... Read More
This field experiment on fababean was conducted with three rates of N (20, 100 and 200 kg/ha) as urea (labeled with 5%, 1% and 0.5% l3N a.e. respectively) and barley was grown as reference crop. Resul ... Read More
A study pertaining to Zn application to two sorghum cultivars, grown under two moisture regimes was conducted. Zinc was applied @ O, 1, 3, 9, or 27 mg kg'1 soil. Zinc concentration and uptake by both ... Read More
A field study was conducted to investigate the effect of five levels of zinc (0. 5, 10, 15. 20 kg ha'1 ) and three levels of boron (0, 0.5 and 1.0 kg ha') on yield and yield components of wheat under ... Read More
A greenhouse pot experiment was conducted to compare growth, P uptake and P efficiency of wheat and triticale at various stages of growht as affected by P fertilization. The results showed that applic ... Read More
