Abstract
Performance of new plant types of wheat (Triticum aestivum L. emend. Fiori & Paol.) was tested with different seed rates and fertilizer doses under ri ce (Oryza sativa L.)-wheat agro-ecosystem during winter season of 1997-98 a nd 1998-99 in sandy-loam soils of Jabalpur, Madhya Pradesh. 'Lok 1' outyiel ded 'Mangla' and 'Kanchan' varieties mainly owing to superiority in effecti ve tillers/m(2), weight of grains/ear and 1,000-grain weight. Application o f 150 kg N + 75 kg P2O5 + 50 kg K2O/ha resulted in maximum grain and straw yields, but a dose of 120 kg N + 60 kg P2O5 + 40 kg K2O/ha was optimum for all the varieties. A seed rate of 125 kg/ha proved ideal for increasing gra in and straw yields.
