Abstract
An experiment was conducted during thc winter season of 1992--93 and 1993-94 on moderatcly acidic sandy-loam soil to study response of wheat (Triticuni aestivum L. emend. Fiori & Iaol.) to crop geometry and weed Innnaganlent. Weedy dry weight was minimum in closer sowing at 15 ctn. Intcrgratcd wced management was 97% eflicient in reducing weed dry weight. Criss-cross sowing at 22.5 cm x 22.5 cm and unidirectional sowing at 15 cm incrcased grain yield by 22.7 and 13.6% coinpared with wider sowing at 22.5 cm. Sicnilarly, straw yield increase was recorded up to 27.3 and 18.2% over wider sowing at 22.5 cm. Criss-cross sowing with integrated weed-management practice Ibi~nd to be the hest combination and gave the maximum yield of 3.1 tonnesha.References
