EFFECT OF FERTILIZER DOSE ON FRUIT YIELD AND ECONOMICS OF OFF SEASON CUCUMBER CULTIVATION UNDER LOW COST POLYHOUSE

摘要

Fertilizer response trails comprising different doses of N+P+K i.e., 75+40+20, 125+50+40, 175+60+60 and 225+70+80 kg/ha were conducted on off-season cultivation of cucumber crop in a low cost polyhouse during 1998 - 99 and 1999 - 2000, to ascertain the optimal dose of N+P+K for the maximum yield of good quality fruits. Results indicate that the application of the dose of N+P+K, 175+60+60 kg/ha produced significantly higher number of fruits (7.12 - 7.15), weight of fruit (329.65- 340.90g), weight of fruits per plant (2.41 - 2.44 kg), yield of fruits (17.8 - 18.04 kg/m2) and net income (Rs.91.86/m~2) as compared to the other fertilizer doses.
