Abstract:
Integrated Plant Nutrition System (IPNS) is a system of planning and management of plant nutrients through crop rotations for enhanced productivity, profitability and sustainability. A field experiment to evaluate the effect of five organic sources of plant nutrients along with three fertility levels on productivity and economics of tomato was conducted during kharif seasons of 2006 and 2007 at HAREC, Kukumseri (L&S). Application of FYM @ 2.5 t/ha in combination with PSB has produced significantly taller plants with higher values of yield contributing characters viz. number of branches per plant, number of fruits per plant, fruit weight, fruit weight per plant and fruit diameter, reflected in getting significantly highest tomato yield (700.9 q/ha), productivity (3.84 q/ha/day) and economic efficiency (` 1549.4/ha/day), which was followed by FYM 5 t/ha for all these characters. With increasing the dose of NPK by 50% over recommended i.e. 150% NPK, the yield contributing attributes were significantly improved, contributing in producing significantly highest tomato yield (767.4 q/ha) and productivity 4.21 q/ha/day with the best economic efficiency of ` 1721.5/ha/day. Increasing 50% NPK beyond recommended resulted in 5.33% higher yield of tomato crop.
