Abstract: Field experiments were conducted during summer season of 2019 and rabi season of 2019-20. The experiments were laid out in split plot design and replicated thrice with four plant spacing in main plot viz., S1- 100 x 10 cm, S2 -75 x15 cm, S3 -60 x15 cm and S4 -45 x15 cm and four levels of nutrients in sub plot viz., Control (without fertilizers), F1 - 100% RDF (80:40:40 kg of NPK ha-1), F2 -125% RDF (100:50:50 kg of NPK ha-1) and F3 -150% RDF (120:60:60 kg of NPK ha-1). The observations on crop growth components, yield components, seed cotton yield and harvest index were observed in both seasons, pooled and statistically analysed. The results revealed that among the different treatment combination, 60 x 15 cm with 125% RDF - 100:50:50 kg of NPK ha-1 (S3F2) registered the highest seed cotton yield (2745 kg ha-1) which was on par with plant spacing of 100 x 10 cm along with 125% RDF (S1F2) recorded 2395 kg ha-1. Hence, these treatment combinations can be recommended for high density planting system (HDPS) in compact cotton cv. CO 17.
