Abstract:

A field experiment was carried out in alluvial agro-climate of zone of West Bengal during rabi, 2015-16 and 2016-17 under the aegis of Bidhan Chandra Krishi Viswavidyalaya at AB block farm, Kalyani. The experimental work was conducted in split-plot design with three replications. Four different date of sowing viz. 1st November, 15th November, 30th November and 15th December were randomly allotted to main-plots, while seven different nutrient management aspect mainly control, 50% RDF, 75% RDF, RDF, 50% RDF + FYM (@10 t/ha), 75% RDF + FYM(@10 t/ha) and RDF + FYM(@10 t/ha) were allocated randomly to sub-plots. More number of grain/spike found with the early date of planting (1st November) and was at par with the 15th November, and appreciably better to other main plots treatments. Amid a range of subplot treatments, highest grain/spike registered with the RDF and was at par with the RDF + FYM (@10 t/ha) and 75% RDF + FYM (@10 t/ha). Highest grain yield registered with the 15th November (37.01 q/ha) sowing, and was at par with the early sowing i.e. 1st November (35.07 q/ha). These treatment increases 72.25 and 61.91 % more grain yield over the extreme late sowing condition i.e. 15th December. Further, 75% RDF + FYM (@10 t/ha) gave more economic yield (37.47 q/ha), and was at par with the RDF + FYM (@10 t/ha), RDF and 50% RDF + FYM (@10 t/ha). More straw yield observed with the 15th November sowing, and was considerably superior to other main plot assignment. Amongst various nutrient management, maximum straw yield found with the 75% RDF + FYM (@10 t/ha), and was at par with all other treatments except control and 50 and 75% RDF. The 15th November sowing, gave more biological yield of wheat crop and drastically better to other main plots treatments. Moreover, with various subplot treatments, better this parameter found with the 75% RDF + FYM (@10 t/ha) and was at par with all other treatments, except control and 50 and 75% RDF application. Maximum, NPK uptake observed with early date of sowing i.e. 15th November compared to extreme late sowing condition i.e. 15th December. More primary nutrient removal observed with the 75% RDF + FYM (@10 t/ha) and was at par with RDF + FYM (@10 t/ha) and notably better to other subplot treatments. Amongst various nutrient management practices, more nutrient uptake found with the 75% RDF + FYM (@10 t/ha) and was at par with the full dose of RDF + FYM (@10 t/ha). Economics revealed that, more net return observed in 15th November planting (` 40, 453), with highest benefit cost ratio (2.04), and was followed by 1st November sowing. Amongst various nutrient management, highest net return (` 40,987) and benefit: cost ratio (2.13) observed with 75% RDF + FYM (@10 t/ha) and was followed by 50% RDF + FYM (@10 t/ha).
