Abstract

Paddy, the most important food crop of Uttar Pradesh, is grown in an area of 59.04 lakh ha with the productivity level of 19.77q/ha. Overall, 16 On-Farm-Trials (OFTs) were conducted at 15 KVKs on different aspects in the city during 2005–06. It was found that improved varieties registered yield gains of 8.56 q/ha. Cropping systems registered yield advantage of 4.35–12.15 q/ha with recommended doses of fertilizers i.e. N: P: K @ 120- 150: 60-: 40 kg/ha, Zinc 25 kg/ha in deficient areas provided additional yield of. 0.98- 7.61 q/ha. The resource conservation technologies viz, use of zero till machine coupled with improved varieties, recommended doses of fertilizers and direct seeded rice with stale bed sowing attained yield advantage of 5.00- 13.60 q/ha. Weed management especially through herbicides application i.e. Pendimethaline @ 3.33 l/ha and Butachlore 50 EC @ 4l/ha provided additional yield of 6.80 q/ha. Organic sources as vermicompost @ 2.5 t/ha and inorganic fertilizer doses provided yield advantage of 2.50 q/ha. Thus, the study concludes that yield advantages can be attained by the use of improved varieties, integrated weed management and resource conservation technologies in farmers' conditions.
