Abstract:

The experiment was conducted to evaluate the effect of tillage methods and Integrated Plant Nutrition System (IPNS) based fertilizer management during 2014-15 at Regional Agricultural Research Station (RARS), Jessore on the productivity of potato. Three tillage methods viz., (i) Bed planting (T1), (ii) PTOS (Power Tiller Operated Seeder (T2) and (iii) Conventional tillage (T3) in combination with five types of nutrient management packages viz., (a) STB fertilizer dose from chemical fertilizer (F1), (b) 120 % of chemical fertilizer over STB fertilizer doze (F2), (c) 80 % from chemical (Soil Test Based fertilizer doze STB) + 20 % from vermi-compost (STB) fertilizer doze (F3), (d) 80 % from chemical (STB) + 20 % from conventional compost (STB) Fertilizer doze (F4), farmers practice (F5) were as the treatments. The experiment was laid out in a split plot design with three dispersed replications. It was found that bed planting was given the highest yield (24.11 t ha-1) followed by PTOS (23.95 t ha-1) and conventional tillage (23.60 t ha-1). In case of fertilizer application it was found that 120 % of chemical fertilizer over STB fertilizer doze gave the highest yield (25.18 tha-1) followed by 80 % from chemical (STB) + 20 % from vermi-compost (STB) (24.11 t ha-1) farmer practice (23.53 t ha-1), STB fertilizer dose from chemical fertilizer (23.48 t ha-1) and 80 % from chemical (STB) + 20 % from convention compost (STB)(23.11 t ha-1). In case of interaction effect of tillage and fertilizers management, it was found that there were no significant effect among them however T2(PTOS) + F2 (120 % of chemical fertilizers over STB fertilizer doze) gave the highest yield (26.33 t ha-1).
