Abstract

In Uttar Pradesh, pulses are one of the major crops with an area coverage of 2.16 million ha. “Bundelkhand” occupies major area where pulses are mostly grown in rainfed situation. The productivity of pulses in the state continues to be quite low (7.31 q/ha) on account of several biotic and abiotic stresses besides unavailability of quality seed of improved varieties and inadequate crop management The per capita availability of pulses is declining as the marginal growth rate in pulses production (???1%) is not keeping pace with population growth. Krishi Vigyan Kendras are addressing the relevant issues by bridging yield gap in pulses by conducting situation specific and problem based on-farm trials. The trials on pigeonpea demonstrated 1.35 q/ ha higher yield from long duration variety as compared to short duration variety, even then short duration variety was preferred as it allows cultivation of one more rabi crop (wheat). The performance of PDM 139 variety of green gram was superior, yielding 4.0 q/ha higher yield as compared to traditional practices and old varieties. Similarly, growing of wilt tolerant lentil variety (Narendra Lentil 1) produced 6.30 q/ha higher yield as compared to old varieties. The trials on nutrient management of fieldpea demonstrated an yield advantage of 5.6 q/ha in the combination of KPMR 400 + Rhizobium culture+balanced fertilizer + weedicide over the farmers’ practice of using old variety and traditional crop management practices. Similarly, balanced use of fertilizer has shown yield advantage of 5.86 q/ha. Management of wilt in pigeonpea by seed treatment with Trichoderma has shown yield advantage of 3.28-6.35 q/ha over farmers’ practice of not treating the seed. Two sprays of Bacillus thuringensis (Bt) @ 750 g/ha + variety + fertilizer application + one spray of endosulphan in chickpea resulted yield of 17.50 q/ha with least pod damage (13 pods/m2). Overall, insect and disease management practices provided an additional yield of 2.75 to 5.10 q/ha, over farmer's practices.
