GROWTH AND YIELD OF BARI TOMATO 11 IN RESPONSE TO APPLICATION OF PHOSPHORUS AND SULPHUR

Abstract

ABSTRACT The present experiment was carried out at the Farm of Sher-e-Bangla Agricultural University, Dhaka-1207 during the period from October 2017 to April 2018 to find out the growth and yield of BARI tomato 11 in response to application of phosphorus and sulphur. The experiment was done with four level of phosphorus viz. 0, 20, 30, 40 kg P ha -1 and four levels of sulphur (viz. 0, 10, 15 and 20 kg S ha -1 ). The experiment was set up in Randomized Complete Block Design (RCBD) with three replications. Data on growth and yield parameters were recorded and analyzed statistically. Results showed that different levels of phosphorus and sulphur significantly influenced all growth and yield contributing characters and yield of tomato. The phosphorus (P) treatment P 2 (30 kg P ha -1 ) showed the highest number of branch plant -1 (5.94), number of flower clusters plant -1 (12.35), number of flowers cluster

(27.49), number of fruits cluster -1 (20.69), number of fruits plant -1 (255.70), number of fruits plot -1 (1023.00), fruit weight plot -1 (7.03 kg) and fruit yield ha (40.15 t) compared to control treatment P 0 (0 kg P ha -1 ). The sulphur (S) treatment S 1 (10 kg S ha -1 ) resulted the the highest number of branch plant -1 (6.05), number of flower clusters plant -1 (12.75), number of flowers cluster -1 -1 (27.13), number of fruits cluster

(20.23), number of fruits plant -1 (253.40), number of fruits plot -1 (1014.00), fruit weight plot -1 (6.87 kg) and fruit yield ha -1 (39.23 t) compared to control treatment S 0

(0 kg S ha -1 ). The treatment combination of P 2 S 1 (30 kg P ha -1 and 10 kg S ha ) performed best in terms of highest number of branch plant -1 (6.64), number of flower clusters plant -1 (13.03), number of flowers cluster (22.10), number of fruits plant -1 -1 (30.07), number of fruits cluster (284.10), number of fruits plot -1 (1136.00), fruit weight plot -1 (7.63 kg) and fruit yield ha -1 (43.59 t). Different doses of P and S nutrients showed significant variation on N, P and S concentration in post harvest plant shoot and root but K concentration in shoot and root was not significant. The treatment combination of P 3 S 3 performed as for N, P, K and S concentration in plant shoot and root compared to control. -1 -1 -1 -1
