Effect of Integrated Nutrient Management Levels on Soybean and its Residual Effect on Production Efficiency and Economic Efficiency under Soybean-Onion and Soybean-Potato Cropping System

Background: Inclusion of high value vegetable crops like onion and potato in soybean based crop sequence may help to improve the productivity and profitability on sustainable basis. Nutrient management and cropping sequence are two important factors which affect productivity and profitability of crop. As such, information on soybean followed by onion and potato is lacking and it will be very useful for exploring the productivity and profitability of soybean followed by high value vegetable crop sequence. Methods: The data pertaining to growth characteristics, yield characteristics, gross monetary returns and net monetary returns of Soybean ( kharif ) and Onion or Potato (rabi ) was collected at regular interval in 2017-18, 2018-19 at Agronomy Farm, Dr. PDKV, Akola which was analyzed statistically in RBD (Randomized Block Design) and SPD (Split Plot Design). Result: S1- soybean-onion recorded more production efficiency than S2- soybean-potato. S1- soybean-onion reported greater economic efficiency than S2- soybean-potato. Soybean crop supplied with IN3 (100% RDN applied with FYM@ 5 t per ha and biofertilizer) registered highest production efficiency and economic efficiency than IN1 ( 50% RDN applied with FYM5 t per ha and biofertilizer) to soybean and found at par with IN2 (75% RDN applied with FYM5 t per ha and biofertilizer) to soybean. Rabi crop (onion/potato) supplied with F3 (125% RDF) level registered significantly greater production and economic efficiency than lower levels of recommended dose nutrient.
