Effect of tillage practices and cultivars on growth and biomass production of wheat (Triticum aestivum L.).

摘要

A field experiment was conducted to study the effect of tillage practices and wheat cultivars on growth and biomass production during rabi of 2002-03. Four tillage practices viz., conventional method, bed planting, surface seeding and zero tillage, and four wheat cultivars viz., HD 2643, HUW-468, PBW-443 and PBW-373, were studied with respect to various aspects of growth and biomass (grain and straw yield) production. Significantly higher grain yield of wheat was recorded with bed planting (40.8 q/ha) which was at par with conventional method (37.3 q/ha). Zero tillage recorded almost equal yield to that of conventional method. The pattern of straw yield and grain straw yield was similar to grain yield. Among wheat cultivars, HUW-468 exhibited superiority in biomass yield followed by PBW-373. Growth attributes were higher in the order of bed planting > conventional method > zero tillage.
