EFFECT OF NPK FERTILIZERS ON CAPSICUM PRODUCTION INSIDE LOW COST POLYHOUSE

Capsicum is an important cash crop of Himachal Pradesh fetching reasonably high market price during off season. Keeping in view the investigations entitled “Effect NPK fertilizers on capsicum production inside low cost polyhouse” were carried out at the research farm of the Department of Agricultural Engineering, CSKHPKV, Palampur (H.P) during summer seasons of 2005 and 2006. The study aimed to find out best combination of NPK as well as the effect of different NPK levels on growth, yield and yield contributing characters of capsicum under low cost polyhouse. The experiments were laid out in RBD (factorial) with three replications. Results of the study revealed that application of 50% more of the recommended dose recorded significantly higher plant height, fruit length, fruit breadth, fruits per plant and fruit yield per plant than other levels of NPK. These effects culminated in increased fruit yield/ha with increasing level of NPK. On an average, 50% more of the recommended dose of NPK recorded 96.10% higher yield over 50% less than recommended dose of NPK.
