Abstract:

A field experiment was carried out during rabi season of 2013-14at Instructional Farm, Bidhan Chandra Krishi Viswavidyalaya, Jaguli, Mohanpur, Nadia, West Bengal to study the effect of different doses of nitrogen and potassium fertilizer on growth and yield of potato. The experiment was conducted under randomized block design replicated thrice. Two different doses of N:P2O5:K2O i.e. 300:150:150 and 200:150:150 kg ha-1respectively were applied. Further N:P2O5:K2O-200:150:150 kg ha-1were split in nitrogen and potassium fertilizer at basal, 28 and 42 DAP along with full dose of phosphatic fertiliser at basal and altogether ten treatments were tested under the experiment. Results revealed that highest growth attributes and yield namely plant height (36.17 cm), LAI (3.12), CGR (40.04g ma-2 day-1), NAR (6.04g ma-2 day-1) and LAD (132.53 days) and tuber yield (28.917 t ha-1) were recorded in case of the treatment where N and K2O applied as basal + 1/4 at 28 and 42 DAP @ 200:150:150 N:P2O5:K2O kg ha-1. Amongst the ten treatments adopted in the experiment, the highest net return ha-1 (Rs.78860.31) and highest return per rupee investment (1.83) were obtained from the treatment where N and K2O were applied as basal + 1/4th at 28 and 42 DAP @ 200:150:150 N:P2O5:K2O kg ha-1.
