Response of wheat (Triticum aestivum) to planting method, seed rate and fertility in late-sown condition

Abstract

A field experiment was conducted during the winter reasons of 1989-90 and 1990-91 to study the response of wheat (Triricum aestivum L. emend. Fiori & Paol.) to planting method, seed rate and fertilizer. Cross-row (22.5 cm X 22.5 cm) planting method gave significantly higher yields (grain + straw), yield attributes and benefrt : cost ratio than other planting methods. Cross and close row (15.0 cm) plantings had smothering effect on weed density and dry weight. Increasing seed rate from 100 to 150 kgha increased the grain and sttaw yields, however benefit : cost ratio was the highest with 125 kg seed/ ha seed rate. Applicatiop of recommended fertilizers (125 kg N + 60 kg P + 50 K kgha) increased the yield and yield attributes. However, benefit : cost ratio was highest with 50% of the recommended fertilizer (60 kg N + 30 kg P +25 kg m a ) .|| Of the various factors responsible for low management on wheat are lacking in flood- productivity, suboptimum plant population prone area of north-eastem plains zone of per unit area and poor fertilizer management Uttar Pradesh in late-sown conditions, an are of paramount importance in wheat attempt was made on this aspects.
