Abstract

A study was conducted to investigate the growth and yield parameters of tea after application of Nano DAP on tea plants during the time frame of February, 2024 to December, 2024. The experiment was done on TV 23 clone of mature tea plants in experimental garden for plantation crops, AAU-Jorhat. The layout was in RBD with four replications and five treatments. Nano DAP was found effective towards the growth of tea plants. The growth and yield attributes of tea plants increased with application of Nano DAP. The growth and yield parameters were recorded significantly higher in treatments T2 (Recommended doses of N, P2O5, K2O +3 sprays of Nano DAP @ 3ml/l) and T3 (Recommended dose of N and K2O + 75% recommended dose of P2O5 + 3 foliar sprays of Nano DAP @ 3 ml/l) over treatment T1 (Recommended doses of N, P2O5 and K2O). The study revealed that the application of three sprays of Nano DAP @ 3ml/l with recommended dose of fertilizers performed similar with reduction of 25 per cent of basal dose of recommended phosphate and recommended dose of nitrogen and potassium along with three sprays of Nano DAP in tea plants. This approach can be a potential and economically feasible method to increase yield of tea plants and to promote the sustainable development of the tea industry.
