Abstract

Results of two field study (1986-87 and 1987-88) conducted at the Soil Conservation and Water Management farm, Kanpur showed that application of N at 60 kg/ha recorded higher root depth and root weight, grain yield and N,P,K uptake. Method of half drilled at sowing + half foliar application of nitrogen showed better results in comparision to drilling entire dose of N as basal. Grain yield of wheat at a row spacing of 20 cm was at par with 25 cm row spacing, during normal rainfall season. During drought season, 25 cm row spacing registered higher yield. The best development of roots was observed in 30 cm row spacing. Application of maize stalk at 4t/ha performed better in comparison to weeding and hoeing in respect of maximum root expansion, yield, rainfall use efficiency and nutrient uptake
