dc.description.abstractThe present investigation entitled “Studies on effect of plant growth regulators in polyhouse grown tomato (Solanum lycopersicum L.)” was carried out at Vegetable Research Farm of the Department of Vegetable Science and Floriculture, CSK HPKV Palampur, Himachal Pradesh during spring-summer and autumn-winter season with the objectives to study the effect of different plant growth regulators on yield, quality and to work out the economics of production under protected conditions. The experiment was laid out in a Factorial Randomized Block Design with three replications and data were recorded on horticultural and quality traits in tomato. The recommended package of practices and plant protection measures were followed from time to time to grow healthy crop. Among the different plant growth regulators GA3 @75 ppm resulted maximum number of fruits per plant, fruit weight and marketable yield per plant, marketable yield per m2 area, ascorbic acid content plant height and minimum number of days to 50 % flowering. Highest fruit yield (27.65 kg/m2 ) with maximum net returns (394.00 /m2 ) and higher benefit: cost ratio (2.48) was obtained with the treatment combination involving T16 (GA3 @ 75ppm + All above three stages) during autumn-winter season. The combined effect of growth regulators at different stages of plant growth showed that A2B4 (GA3 @ 75 ppm sprayed at flowering stage) and A2B1 (NAA @ 50 ppm sprayed at flowering stage) recorded maximum (27.40 and 30.97 mg/100 g) ascorbic acid content for first and second season. The combined effect of growth regulators at different stages of plant growth showed that A2B4 (GA3 @ 75 ppm sprayed at flowering stage) recorded maximum (24.59 kg and 27.65 kg) marketable yield per m2 during both the seasons which was significantly superior from all other two-way interactions. Therefore, it has been concluded that tomato plants sprayed with GA3 @ 75ppm at flowering stage recorded maximum marketable yield and its contributing characters.en_US
