EFFECT OF GIBBERELLIC ACID AND CLYBIO ON GROWTH AND YIELD OF SAU YELLOW CHERRY TOMATO

Abstract

An experiment was conducted in Horticulture Farm, Sher-e-Bangla Agricultural University, Dhaka-1207 during December 2021 to April 2022. The study was carried out to investigate the effect of different concentrations of gibberellic acid (G 0: 0mg/L, G 1 : 25mg/L, G 2 : 50mg/L) and different concentrations of clybio (C 0 : 0ml/L, C 1 : 4ml/L, C 2 : 6ml/L) on growth and yield of the SAU yellow cherry tomato. The experiment was conducted in Randomized Completely Block Design (RCBD) with 3 replications. For this study, data were calculated on average plant height, number of branches, number of clusters, number of flowers per plant, number of fruits per plant, fruit length, fruit weight, yield per plant, SPAD value. The maximum plant height (199.8 cm), maximum number of branch (6.3), maximum number of clusters (31.7), the highest number of flowers per plant (2685.7), highest number of fruits per plant (1212.3), maximum fruit length (26.3 mm), highest individual fruit weight (8.8 g), maximum average yield per plant (10.7 kg), maximum SPAD value (71.7) were found in G 2 C 2 concentration (G 2 -6 ml/L). While the minimum plant height (149.2 cm), minimum number of branch (3.7), minimum number of clusters (18.0), minimum number of flowers per plant (1295.3), minimum number of fruits per plant (590.7), minimum fruit length (18.3 mm), the lowest individual fruit weight (5.5 g), minimum average yield per plant (3.3 kg), minimum SPAD value (46.6) were found in G 0 C 0 (No treatment/control). G 2 C 2 concentration (G 2 -50 mg/L, C 2 -6 ml/L) is the prominent application on growth and yield of SAU yellow cherry tomato.
