ABSTRACT
A field experiment was conducted for two consecutive years during rabi seasons of 2014-15 and 2015-16 at instructional farm of Uttar Banga Krishi Viswavidyalaya, Pundibari, CoochBehar, West Bengal to identify suitable time of planting and nutrient management for optimal plant growth and yield of potato under terai region of West Bengal. The experiments were laid out in split-plot design and replicated thrice with three planting dates as main plot: 15th November (D1), 30th November (D2) and 15th December (D3) and seven different levels of nutrient management treatments as sub-plots : 100 % of the recommended dose of fertilizer (RDF) N2, P2O5, K2O @120:100:100 kg ha-1 through chemical fertilizer (CF) (N1),75% of the RDF through CF + vermicompost @ 5t ha- 1 (N2), 75% of the RDF through CF + FYM @10 t ha-1 (N3), vermicompost @ 15 t ha-1 + azotobacter (N4), FYM @ 20 t ha-1+ azotobacter (N5), FYM @ 10 t ha-1 + vermicompost @ 10 t ha-1+ azotobacter (N6), Control (N7). Among different dates of planting and nutrient management treatments, planting on 15th November with nutrient combination of 75% of the RDF through CF + vermicompost @ 5t ha-1showed better field emergence, growth and tuber yield. It can be concluded from the study that for achieving higher tuber yields in potato under terai region of West Bengal, the crop should be planted on 15th November with 75% of the RDF through CF + vermicompost @ 5t ha-1. However, considering the reality of North Bengal condition as the land remain occupied by earlier kharif rice in early weeks of November also. It is advised to plant potato in 30th November with INM centered around 75% of the RDF through CF + vermicompost @ 5t ha-1or75% of the RDF through CF + FYM @10 t ha-1 to achieve significantly higher tuber yield.
