Abstract
Any increase or decrease from optimum temperature results in premature drop of tomato fruit Night temperature also plays an important role in the setting and development of the fruit, as night temperature below 10 C significantly affects the fruit set in tomato Adam et al. (2001) while evaluating the impact of temperature on growth and development of tomato fruit, reported that temperature below 14C greatly reduces the tomato growth and causes the Abstract | Flowering in Solanum lycopersicum L. is sensitive to low-temperature as it inhibits the fuit growth and causes poor fruit setting. The present experiment was conducted to improve the fruit growth and fruit set in tomato during low-temperature stress conditions by the use of growth regulator 4-chlorophenoxy acetic acid. Seven different 4-chlorophenoxy acetic acid levels along with two indeterminate tomato varieties saandal and sahel were tested in two minimum night temperature conditions 12.5-23C and 2-7.5C. Tomato yield per plant, yield per cluster, number of fruits per cluster, fruit weight and fruit diameter were significantly improved by the application of 4-chlorophenoxy acetic acid. Highest yield per plant 13.50 kg was recorded with the application of 75 ppm in 4-chlorophenoxy acetic acid twicely when the minimum temperature was ranged between 12.5-23C. Likewise, maximum yield per plant 7.08 kg was also obtained with the same treatment when the minimum temperature was between 2-7.5C. This gain was primarily due to increased yield per cluster, fruits per cluster, fruit weight and fruit diameter in both minimum night temperature conditions (12.5-23C and 2-7.5C). 87 % gain in yield per plant was observed with 75 ppm double sprayed treatment over control when minimum night temperature varied between 2-7.5C. Successful yield increase per plant suggested that 4-CPA could be used as a tool for getting economical tomato yield when night temperature falls below 10C.
