Title: Effect of Intercropping and INM practices on yield and returns of Chilli (Capsicum annum.L)

Abstract: The present investigation was carried out to study the impact of intercropping and integrated nutrient management on yield and returns of chilli during late kharif 2015 and 2016 at College of Horticulture, Venkataramannagudem. The experiment was laid out in split plot design with five main plot treatments i.e sole chilli (M0), four intercrops onion (M1), coriander (M2), fenugreek (M3) and marigold (M4) combined with five sub plot treatments viz., 100% RDN through urea (S0), 25% RDN through FYM + 75% RDN through urea (S1), 25% RDN through vermicompost + 75% RDN through urea (S2), 25% RDN through poultry manure + 75% RDN through urea (S3) and 25% RDN through neem cake + 75% RDN through urea (S4), consisting of 25 treatment combinations, replicated thrice. All the intercrops, except marigold, positively influenced green and dry chilli yield of chilli over chilli sole cropping. Chilli + fenugreek (M3) treatment recorded maximum values for yield and yield attributing parameters of ripe and dry chilli. The competitive functions like LER, ATER indicated fenugreek and coriander were the better intercrops in chilli with 14% and 12% yield advantage respectively over chilli sole cropping, whereas, onion recorded an advantage of 6% only. Among the intercrops, chilli + marigold (M4) treatment recorded the minimum values in terms of yield and returns. Among the INM treatments, application of 25% RDN through neem cake + 75% RDN through urea (S4) treatment recorded the highest green and dry chilli yield over application of 100 % RDN through urea (S0). Among the interactions, the chilli, intercropped with fenugreek and applied with 75% RDN through urea + 25% RDN through neem cake (M3S4) was found superior in terms of yield. However, the maximum gross and net returns were obtained in chilli + onion and lowest gross returns and B:C ratio were obtained in chilli + marigold system irrespective of INM treatments. Among all the treatment combinations, chilli intercropped with onion + 25% RDN through FYM + 75% RDN through urea (M1S1) recorded the maximum B:C ratio (5.86) followed by chilli intercropped with onion + 25% N through poultry manure + 75% RDN through urea (M1S3) (5.28). The minimum B:C ratio was reported in chilli intercropped with marigold and applied with 100% RDN through urea (M4S0) (1.39).
