Abstract

                                An investigation was carried out to assess the growth and yield of hybrid tomato (Solanum lycopersicum L.) under shade net using farm yard manure (FYM) and graded doses of N,P,K along with different biofertilizers viz., Azophos, Methylobacterium and Azophosmet. The experiment was conducted at the Department of Horticulture, Agricultural College and Research Institute, Madurai. The experimental results revealed that the growth attributes viz., plant height, number of branches, number of leaves, crop growth rate, relative growth rate, dry matter production and leaf chlorophyll content were enhanced with the application of 50 per cent recommended dose of N, P and 100 per cent recommended dose of K + 2 kg Azophosmet ha-1 in both the season. Further, the yield parameters namely, number of inflorescence per plant, number of fruits per plant, individual fruit weight, fruit yield per plant, fruit yield per plot and fruit yield per hectare were also found to be highest with the application of 50 per cent recommended dose of N, P and 100 per cent recommended dose of K + 2 kg Azophosmet ha-1 in both the seasons.

Key words : Hybrid tomato, Azophos, Methylobacterium, Azophosmet.
