EFFECT OF CCC ON GROWTH, MORPHO-PHYSIOLOGICAL PARAMETERS AND YIELD OF TOMATO AT DIFFERENT MOISTURE LEVELS

Abstract

An experiment was conducted at Horticulture farm, Sher-e-Bangla Agricultural University, Dhaka to study the effect of Chlorocholine chloride (CCC) on growth, morpho-physiological parameters and yield of tomato at different moisture levels. The experiment was laid out in a Completely Randomized Design with 3 replications and comprised of two factors: Factor A; (i) I = 100% ET (Evapotranspiration) moisture, (ii) I 1 = 80% ET moisture and (iii) I 2 0 = 60% ET moisture and Factor B; (i) F 0 = Foliar spray with water (control), (ii) F = Foliar spray with 1000 ppm CCC and (iii) F 2 1 = Foliar spray with 2000 ppm CCC. Application of different ET moisture with diffeent CCC levels showed significant variation on most of the parameters. In case of ET moisture levels, the highest fruit length (6.11 cm), fruit diameter (6.82 cm) and the highest total fruit weight plant -1 (1.23 kg) were recorded from I The highest number of fruits sets plant -1 (29.11), highest fruit length (6.40 cm), highest fruit diameter (6.73 cm) and the highest total fruit weight plant -1 (1.48 kg) were found from F 1 . Regarding the combined effect, the highest fruit length (6.81 cm), maximum diameter of fruit (7.21 cm) and the maximum total fruit weight plant (1.27 kg) was found from the treatment combination I 1 F . So 80% ET moisture and foliar spray of 1000 ppm CCC showed better performance for growth and yield of tomato.
