GS-600 under polyhouse condition Pooshpendra Singh Dixit, VM Prasad, Saurabh Kasera and Shivendra Singh Abstract An investigation was carried out at Research Field, Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj during Rabi season of 2017-18, to assess the effect of various organic inputs on growth and its attributes of tomato under polyhouse condition. The experiment was laid out in randomized block design with 10 treatments replicated thrice. The treatments consisted of different combinations of organic manures i.e., FYM, Vermicompost and Poultry manure. The data were collected from five randomly selected plant of each treatment and subjected to statistical analysis. The results reflected that among 10 treatments under study, treatment T6 (Vermicompost 50% + Poultry manure 50%) was best in all characters and recorded maximum @ 30, 60, 90 and 120 DAT in term of plant height (56.68cm, 94.99cm, 199.44cm and 250.31cm, respectively), No. of branches per plant (6.00, 8.47, 15.47 and 25.93, respectively) and No. of leaves per plant (6.93, 12.67, 23.53 and 36.07, respectively); and better vegetative growth promoted the flowering by producing more clusters per plant with the application of Vermicompost 50% + Poultry manure 50% in treatment T6 which were significantly highest in terms of number of clusters per plant (7.60), number of flowers per cluster (9.01) and number of flowers per plant (56.61); whereas similar trend was closely followed by the treatment T7 (25% Vermicompost + 75% Poultry manure) for these traits, while the constantly lower performance in similar growth and flowering traits at all growth stages was recorded with treatment T0 (Control). These findings are reliable for enhancing organic tomato production under protected cultivation. Keywords: Tomato (Solanum lycopersicon L.), FYM, vermicompost, poultry manure Introduction Tomato (Lycopersicon esculentum L.) belongs to family Solanaceae having chromosome number (2n=24). It is a self-pollinated crop and Peru-Equador region is considered to be the centre of origin. Tomato was introduced by the Portuguese. Tomato is cultivated in tropics and subtropics of the world and it is being cultivated in kitchen gardens, commercial fields under green house and polyhouse conditions and soil less culture or hydroponic systems. Tomato is one of the popular vegetables of great commercial value and is used in various forms of salad, soup, ketchup, sauce, chutney, pickles, powder, paste, juice, puree, whole canned fruits. Tomato is a rich source of vitamins, minerals, organic acids, sugars, ascorbic acids, acidity and Iycopene (Beutner 2001) [1] . Consumption of tomato and its products can significantly reduce the risk of developing of colon, rectal, and stomach cancer. Recently studies suggest that tomatoes contain the antioxidant Lycopene, which markedly reduces the risk of prostate cancer (Kanwar 2011) [4] . Tomato juice promotes gastric secretion, acts as a blood purifier and works as intestinal antiseptic. Tomato is most popular vegetable grown in the world. It can be grown under open as well as protected condition throughout the world for supplying in the fresh market as well as for processing. Tomato is thermo-sensitive crop and fruit set is adversely affected when night temperature falls below 13 ˚ C or day temperature exceeds 30 ˚ C. The optimum temperature required for this cultivation is 15 – 27 ˚ C. Prevailing low temperature and frost injury winter are limiting factors in North India and hills to make their cultivation successful in winter and spring summer season, polyhouse is a vital solution. Due to erratic behavior of weather, the crops grown in open field are often exposed to fluctuating levels of temperature, humidity, wind flow etc. which ultimately affect the crop productivity adversely (Abdel-mawgoud 2007) [1] . Besides this, limited availability of land for cultivation hampers the vegetable production.
