|Title:||Productivity of tomato in relation to seasons and growing conditions|
|Publisher:||Department of Olericulture, College of Horticulture, Vellanikkara|
|Abstract:||Investigation on productivity of tomato in relation to seasons and growing conditions was carried out in two seasons, viz. January to April 2001 (summer) and June to September 2001 (kharif) under two growing conditions (polyhouse and open field) in the Vegetable Research Farm of Department of Olericulture, College of Horticulture, Vellanikkara, Thrissur. The experiment was laid out in competely Randomised Block Design with seven replications. Two bacterial wilt resistant varieties, viz. Sakthi and Mukthi and one F) hybrid COTH-1 were used for the study. The study revealed that crop raised in summer season had more number of branches per plant, LAI, RGR while plant height was maximum during kharif season. Days to 50 per cent flowering was less in summer and number of inflorescence per plant and flowers per inflorescence were higher during summer season. Percentage of fruit set (43.35%) and number of fruits per plant (14.91) were also higher during summer season. Maximum fruit yield per plant (397.52 g) obtained from crops grown during summer season. Crops grown under polyhouse showed more plant height, Number of branches per plant, LAI and RGR. Number of inflorescence and flowers per inflorescence were also higher under polyhouse condition. Percentage of fruit set (43.35%) and fruit yield per plant (397.52 g) were higher under open field condition. Days to 50 per cent flowering (55.99 days) and days to first harvest (94.64 days) were less under open field condition. Evening relative humidity had significant positive correlation with growth characters during summer season whereas minimum temperature exhibited significant but negative correlation with fruiting characters under both the seasons. Pests and diseases incidence were comparatively higher under polyhouse condition under both the seasons due to higher temperature (34.7 to "- The realised yield gave a B/C ratio of ,0.22 under polyhouse and 0.46 under open field conditions. But the B/c ratio under expected yield was 1.14 and respecti vely. 1.58 for crops under open field and polyhouse conditions|
