Abstract

Keeping in view of lack of recommended rates of N and NPS fertilizers, a field experiment was conducted to evaluate the effect of the newly introduced NPS fertilizer and nitrogen on growth, physiology and above ground biomass of garlic. Four NPS (0-0-0, 78. 75-69-12.75, 105-92-17 and 131.25-115-21.25 kg N-P-S ha -1 ) and three nitrogen fertilizer rates (114.13, 228.26 and 278.33 kg N ha -1 ) were laid out in Randomized Complete Block Design with three replications. Significantly highest plant height (28.02 cm), leaf diameter (1.27 cm), dry and fresh weight (4.71 g and 6.11 g) and leaf length were recorded on garlic plants supplied with 105-92-17 kg N-P-S ha -1 and also the highest plant height (27.75 cm), leaf length (24.02 cm), fresh and dry weight (6.23 g and 5.04 g) were recorded on garlic plants supplied with 278.33 kg N ha -1 . The interaction effect also show a significant effect in almost all the growth parameters; the early day to 50% emergence was recorded from a plot which received 228.26 kg N ha -1 and 105-92-17 kg NPS ha -1 and the highest plant height, leaf length, fresh and dry above ground biomass and leaf diameter were 29.
