| dc.description.abstract | The present investigation was undertaken to assess the response of different nutrient management practices on different varieties of garden pea and chilli. The field experiment comprised of 15 treatments which was conducted in chilli-garden pea sequence during two consecutive growing seasons of 2020-21 and 2021-22 following split plot design, replicated thrice. The main plot treatments consisted of five nutrient management practices (75, 100 and 125% of recommended NPK, organic farming and natural farming) while sub-plot treatment comprised of three varieties each of chilli and garden pea. Different nutrient management practices and varieties significantly influenced yield and majority of its attributes in both the crops along with NPK uptake and available N, P and K content in soil. The interaction effects between nutrient management practices and varieties were also significant for yield (fresh/red ripe/dry in chilli and fresh/seed in pea), many important traits, N, P and K uptake, monitory gains in respective crops and chilli equivalent yield. Application of 20 tonnes/ha + 125% NPK resulted in significantly higher mean marketable green, red ripe and dry fruit yield of 254.22, 209.64 and 57.30 q/ha with net returns of Rs. 2.89, 3.27 and 6.62 lakhs/ha, respectively over years in chilli. Similarly, this treatment when applied in pea genotype DPP SP-6 also resulted in maximum average pod and seed yield of 166.64 and 27.25 q/ha along with net returns of Rs. 2.53 and 1.60 lakhs/ha, respectively in pooled data over years. Natural farming practice showed least performance for all the traits in both the crops while organic farming practice found better than natural farming. The maximum N, P and K uptake was recorded in treatment supplemented with 20 tonnes of farmyard manure + 125% of recommended NPK in both the crops. At the end of the experiments, treatment supplemented with 125% NPK increased available N, P and K levels in the soil by 55.96, 8.05 and 44.14 kg/ha over the initial status of the soil. Application of 125% NPK resulted in significantly highest chilli equivalent yield of 510.48 q/ha in Him Palam Mirch 2 mean over years with an increase of 8.3% over recommended practice of 100% NPK in the same variety. Therefore, it can be concluded that treatment supplemented with 125% NPK resulted in maximum yield advantage and economic returns in chilli-garden pea sequence while organic farming performed better than natural farming. | en_US |
