Abstract:

A field experiment was conducted at District Seed Farm (AB Block), Kalyani, under Bidhan Chandra Krishi Viswavidyalaya during the winter season of 2018 and 2019 in an upland situation to assess the performance of wheat under different sowing dates along with tillage option in late sown condition. The experiments were laid out in split plot design with four dates of sowing (25th November, 05 December, 15 December, and 25th December) confined in main plots and four tillage practices (viz. surface seeding, zero tillage, minimum tillage, and conventional tillage) in subplots and replicated thrice time. Wheat cv. ‘DBW 107’ All yield attributes were significantly influenced by the date of sowings. Early sowing revealed more effective tillers followed by higher grain per panicle and test weight. Various tillage practices, which were studied, showed significant variation for all yield-attributing traits. The effective tiller/m2 was highest with minimum tillage and was at par with zero and conventional tillage practice and significantly superior to other measures. The final yield of a crop is the net result of growth and developmental activities in individual plants, which in turn would depend upon the genetic potential of the cultivars and the environmental condition to which it is exposed during the life cycle. The maximum and significantly more grain yield was obtained with 05th December sowing (34.15 q/ha) and showed parity with 25th November (33.89 q/ha) and 15th December (30 q/ha) sowing. This reduced grain yield drastically by the tune of 32.4, 31.6, and 22.7% less compared to the last date of sowing. Further straw yield was more found with the 25th November, and was at par with the 05 and 15th December sowing. With tillage measures, a significantly better grain yield (35.44 q/ha) was recorded with minimum tillage and was at par only with zero tillage (32.14 q/ha). Nutrient uptake patterns varied significantly concerning different wheat sowing measures. Sowing on 05th December registered more N, P, K uptake and was significantly better than all other main plot treatments, except for phosphorous, which showed parity only with the 25th November sowing. Further with various tillage measures, maximum nitrogen and phosphorus uptake was registered with minimum tillage than the other treatments and was at par only with zero tillage and significantly better than other treatments.
