GROWTH, FRUIT SET AND YIELD OF SUMMER TOMATO INFLUENCED BY 4-CPA AND VERMICOMPOST

Abstract

A pot experiment was conducted during the period of April 2017 to October 2017. The research work was conducted at the Horticulture farm of Sher-e-Bangla Agricultural University, Dhaka. The experiment consisted of two factors. Factor A: Four levels of 4-CPA viz., H : Control, H 1 : 15 ppm, H 2 : 45 ppm, H : 75 ppm and Factor B: four levels of vermicompost i.e. VC 0 : Control, VC 3 1 : 500 g/pot, VC 2 : 1 kg/pot, VC : 1.5 kg/pot respectively. The experiment was laid out in Completely Randomized Design method with three replications. 4-CPA and vermicompost showed significant variations with most of the parameters. In case of 4-CPA the highest amount of yield (3.23 kg/plant) was recorded from H 3 and lowest (2.37 kg/plant) from H . For vermicompost, the highest amount of yield (3.31 kg/plant) was from VC 0 and lowest (2.34 kg/plant) from VC . For combine effect the highest yield (3.66 kg/plant) was noted from H 0 3 VC and the lowest (0.95 kg/plant) from H 0 VC 0 3 . So, the use of 75 ppm 4-CPA with 1.5 kg vermicompost gave best result for growth and yield of summer tomato.
