A field experiment was conducted during rainy (kharif) and winter (rabl] seasons of 1999-2000 and 2000-01 at Modipuram in Meerut district to identify the most suitable rice (Oryza sativa L.) variety for direct seeding under unpuddled conditions, and also to study the effect of sulphur and weed-control measures on rice-wheat (Triticum aestivum L. emend. Fiori & Paol.] system. Rice varieties 'DRRH 1' and 'Jaya' recorded mean yields of 71.5 and 66.7 qlha respectively, which were significantly higher than of 'PAC 808' (50 qlha) and 'Pusa Basmati' (45.8 q/ ha). Application of sulphur @ 30 kglha and weed control did not influence the productivity of both the crops. However, application of isoproturon @ 1.25 kglha + 2, 4-D @ 0.8 kglha significantly affected the mean yield (49.3 qlha) of wheat than hand-weeding (47.4 qlha). Rice 'Jaya' - wheat (Rs. 39,0941ha) and rice 'DRRH 1'- wheat (Rs 38,8281ha) system gave significantly higher net returns than rice 'Pusa Basmati 1'-wheat (Rs 37,7521 ha) and rice 'PAC 808'-wheat (Rs 33,8711ha) systems.References
