Considering the current scenario of rising population but stagnant cultivable area, there is a need to enhance crop productivity. Usually, over-application of chemical fertilizers in high-yielding cultivars are used to achieve this objective which is not only reducing agricultural net profit but also deteriorating the soil and human health. Thus, present study was undertaken to evaluate alternatives like INM approach in order to overcome this challenge. The experiment was conducted in randomized block design with three replications and eight treatments comprising different doses of RDF with biocompost in combination with SOB and PSB on during the Rabi season of 2021-22 at Agriculture farm, School of Agriculture, Lovely Professional University, Phagwara. The maximum plant height was recorded under the application of 75% RDF +5 t/ha biocompost + SOB @ 10 ml/kg seed (T5) at 30, 60 and 90 DAS interval which was 61.13, 117.53, and 133.89 cm, respectively. At 30, 60 and 90 DAS, number of leaves per plant were found to be highest (6.79, 37.50, 12.09 respectively) under T3 i.e., application of 75% RDF + 5 t/ha biocompost, while 75% RDF + 5 t/ha biocompost + PSB @ 10 ml/kg seed (T4) resulted in higher number of branches per plant (2.51, 6.17, 9.85) at different stages of growth in 30, 60 and 90 DAS, respectively. Yield attributes, cost of cultivation, gross returns, net returns and B:C ratio significantly increased with the application of 75 % RDF + 5 t/ha biocompost + SOB @ 10 ml/kg seed (T5). The results achieved can pave a better path for attaining the goal of higher productivity, profitability as well as sustainability.

Integrated nutrient management, Biocompost, Agricultural productivity.

As evident from the results, application of 75% RDF + 5 t/ha biocompost in conjugation with either SOB or PSB produced better growth and yield attributes, yield and economic returns in toria. Therefore, it can be concluded that for achieving better crop productivity and profitability in toria, it is better to go with integrated nutrient management practices over sole use of chemical fertilizers. This will also aid in maintaining environmental quality as well as in achieving agricultural sustainability.
