EFFECT OF DRIP IRRIGATION AND NITROGEN FERTIGATION LEVELS ON YIELD AND WATER PRODUCTIVITY OF CABBAGE (Brassica oleracea, L.) UNDER POLYHOUSE CONDITIONS.

Abstract

A field experiment was conducted to study the effect of drip irrigation on yield and water productivity of cabbage under polyhouse conditions. Cabbage is an important and extensively grown vegetable crop under varied agro-climatic conditions. Cultivation of vegetables in polyhouse condition protects the crop against biotic (pests, diseases and weeds) and abiotic (temperature, humidity and light) stresses and ensures year round production of high quality vegetables like capsicum, cabbage etc especially during the off-season. Vegetable cultivation in polyhouse not only increases the productivity but also, enhances the quality of vegetables and it is being practiced in more than fifty countries all over the world.
