The concept of modern horticultural technologies has widened the horizon of vegetable industry in India. The crops grown in open conditions are often exposed to varying levels of temperature, humidity, wind flow etc., which ultimately influence the productivity as well as quality of a crop extensively. Various horticultural practices likes as training, pruning, pollination, PGRs and mulching in protected cultivation found significant for achieving higher yield of various vegetable crops. In tomato, single stem training results better vegetative and reproductive character of plant. While, in case of capsicum four leader system found higher yield and its attributes. In case of PGRs, NAA@20 ppm significantly improve the marketable yield. In case of pollination, bumble bee found best for fruit set and higher yield under poly house conditions. Use of black and double shaded as well as transparent polythene mulch gave higher yield with good quality fruits.
