ABSTRACT
A field experiment was conducted during kharif season of 2011 on a sandy loam soil (Alfisol) at Student’s Farm, College of Agriculture, Rajendranagar, Hyderabad with a view to study the effect of levels of nitrogen (0, 60, 120 and 180 kg N ha-1) and potassium (0, 30, 60 and 90 kg K ha-1) on pod yield, total dry matter production, total nutrient content and uptake by okra at harvest (90 DAS). Randomized Block Design (RBD) with factorial concept was followed. The pod yield of okra was significantly increased with nitrogen, potassium and their interactions. Among the different interactions (N×K), the highest pod yield (126.17 q ha-1) was recorded by combined application of nitrogen @ 180 kg ha-1 + potassium @ 90 kg ha-1 (N3K3). Similarly the highest total dry matter production (5152.9 kg ha-1), highest total N (3.38%) and K (2.97%) content and highest total N (83.83 kg ha-1) and K (75.19 kg ha-1) uptake were recorded with combined application of 180 kg N ha-1 + 90 kg K2O ha-1 (N3K3).
Key words: Total drymatter production, total nutrient content, total nutrient uptake, yield, okra.
