RESPONSE OF INTEGRATED PLANT NUTRIENT MANAGEMENT ON GROWTH, YIELD AND ECONOMICS OF ONION UNDER FARMERS FIELD CONDITIONS
Journal Title: International Journal of Agriculture Sciences - Year 2016, Vol 8, Issue 47
Abstract
The present investigation was conducted by Krishi Vigyan Kendra, Dewas for five consecutive years from 2011-12 to 2015-16 to find out the effect of Integrated Plant Nutrient Management (IPNM) on the performance of the onion crop during rabi season. Demonstration on IPNM were conducted by applying FYM (10 t/ha) + NPKS (130:50:50:20 Kg/ha) + Zinc (5 Kg/ha) + Azospirillum and PSB each @ 5 Kg/ha followed by dipping of seedling roots in 1% Azotobacter solution. The results showed that the growth, yield and yield attributing characters perform well under IPNM plots. The plant height, number of leaves per plant, neck thickness, bulb diameter and bulb weight was found highest in demonstration plots as compared to farmers practice. The average bulb yield recorded in IPNM practices was 303.89 q/ha which was more than local check plots (272.34 q/ha). The increment in yield over local check was 13.64 percent. The technology gap, extension gap and technology index was 21.11 q/ha, 31.55 q/ha and 9.54 percent respectively. An average of Rs.194805 per hectare net profit was recorded under demonstration plots while it was Rs. 169037 per hectare under farmers practice. The benefit cost ratio was highest in demonstrations (4.57) as compared to farmer’s practice (4.22).
