    Nutritional requirement of pre-release sesamum culture 42-1 in garden land
    (Department of Agronomy, College of Agriculture, Vellayani, 1987) Raveendran Nair, P; Chandrasekharan, P
    A 4 raise to 3 fatorial experiment confounding NPK (3 df) totally in replication I and II was conducted under garden land condition at the Instructional Farm, College of Agriculture, Vellayani, during semirabi season 1984, to study the effect of graded doses of nitrogen (10, 30, 50 and 70 kg/ha), phosphorus (5, 15,25 and 35 kg P2O5/ha) and potassium (10, 30,50 and 70 kg K2O/ha) on the growth , yield , quality, content and uptake of mineral nutrients and also to work out the economics of production with the pre-release sesamum culture 42-1 (now released as Soorya or ACV-2). The study revealed that application of nitrogen significantly influenced growth , yield and yield attributing characters. Phosphorus and potassium produced significant influence on number of leaves and leaf area index on 40 and 60 days after sowing. Significant effect of phosphorus was also observed on number of branches, pod-seed ratio, bhusa yield, thousand seed weight and total dry matter production. Applied potassium significantly influenced the yield and yield attributing characters like number of pods , weight of pod per plant, pod seed ratio, seed yield and harvest index.
