Description |
A field experiment was conducted on clay loam soils of Agricultural College Farm, Bapatla to study the ‘Planting density and nitrogen influence on seed yield of jute (Corchorus olitorius L.)’during kharif, 2011. The treatments consisted combination of three planting densities (333333, 222222 and 111111 plants ha-1) and four nitrogen levels (40, 80, 120 and 160 kg ha-1) arranged in a randomized block design with factorial concept and the treatments were replicated thrice. Planting density affected the plant height significantly and the taller plants were produced at higher density (333333 plants ha-1) than at lower planting density (111111 plants ha-1). The maximum plant height was obtained with 160 kg N ha-1. However, no significant differences were observed among 160 and 120 kg N ha-1 in increasing the plant height. Higher drymatter accumulation was observed with higher planting density of 333333 plants ha-1 than 222222 and 111111 plants ha-1. Application of 160 kg N ha-1 significantly enhanced the drymatter accumulation over 40, 80 and 120 kg N ha-1. Crop sown at higher planting density (333333plants ha-1) reached the stage of 50% flowering and maturity earlier than the plants sown at lower planting densities. Crop fertilized with of 160 kg N ha-1 took significantly more number of days to attain 50 per cent flowering and maturity which was on a par with 120 kg N ha-1 and was superior to other levels of nitrogen. The yield parameters viz., number of capsules per plant and number of seeds per capsule of jute was significantly reduced with increase in planting density from 111111 to 333333 plants ha-1. The number of capsules per plant and seeds per capsule were significantly higher in the treatment that received 160 kg N ha-1 over other N levels, however, the differences were not significant between 120 and 160 kg N ha-1 levels. Test weight was not affected by planting density. The maximum test weight was recorded at160 kg N ha-1 than all other levels of nitrogen. The seed yield was significantly higher at maximum planting density of 333333 plants ha-1 than 111111 plants ha-1. However, it was on a par with that obtained at 222222 plants ha-1. The seed yield of jute was the highest with 160 kg N ha-1 which was on a par with that of 120 kg N ha-1 and was superior to rest of the N levels. Stalk yield produced by the planting density of 333333 plants ha-1 was significantly higher than 222222 and 111111 plants ha-1. Application of 160 kg N ha-1 significantly improved the stalk yields of jute than other levels of nitrogen. The total uptake of N, P and K was significantly higher at higher plant population of 333333 plants ha-1 than lower plant populations. The total uptake of nutrients increased significantly with increasing levels of nitrogen and maximum uptake was with 160 kg N ha-1 than other levels of nitrogen. The highest net returns and returns per rupee of investment were obtained with the application of 160 kg N ha-1 at a planting density of 222222 plants ha-1. Overall, the results showed that sowing of jute at a planting density of 222222 plants ha-1 at a spacing of 45 cm x 10 cm was found optimum with a quadratic response upto 160 kg N ha-1 during kharif that resulted in higher net returns and returns per rupee of investment. |
