ABSTRACT
This study was carried out to identify suitable agronomic combination for drought mitigation. The experiment was conducted at Oilseeds Research Unit, Dr. P.D.K.V, Akola, during 2016-17 using a factorial Randomized block design with three replications. The treatment consisted of plant population viz., 1.66, 1.11, 0.83 and 0.66 lakh plants/ha along with three fertilizer levels viz., No fertilizer, 50% RDF and 100% RDF. The branches per plant, effective capsules per plant, 100 seed weight and harvest index significantly decreases as plant population increases. As the plant population increased, seed yield and biological yield was increased. The highest seed yield was obtained from plant population 1.66 lakh/ha (1303 kg ha-1) which was on par with 1.11 lakh ha-1 plant population (1218 kg ha-1) and lowest seed yield was recorded in 0.66 lakh/ha plant population (832 kg ha-1). Application of 100 % RDF (40:25:00 kg NPK ha-1) recorded significantly superior seed yield (1339 kg ha-1) over the No Fertilizer and 50 % RDF level. Similar trend was noticed in gross return, net return and B:C ratio. The interaction between plant population and fertilizer levels found significant. The application of 100 % RDF recorded highest seed (1683 kg ha-1) and oil yield (469 kg ha-1) for 1.66 Lakh plant population which was on par with the normal plant population.
