Abstract

An experiment was conducted during the Rabi season of 2022-23 at the Department of Agriculture, Lovely Professional University in Phagwara, Jalandhar (Punjab). The objective was to explore the implications of integrated nutrient management on the growth, yield and economic feasibility of toria. The experiment followed a randomized block design with three replications and consisted of twelve different treatments. Results revealed that treatment T2 (50% RDF + 50% RDN through Vermicompost) attained the highest values in plant height (61.05 cm, 120.21cm and 140.97 cm), number of primary (7.62 and 9.84) and secondary (8.17 and 11.34) branches, dry matter accumulation (8.30 g plant-1, 28.34 g plant-1 and 65.53 g plant-1) at all observation stages of the experiment which are statistically at par with treatment T3. In terms of yield attributes and yield of toria, treatment T2 (50% RDF + 50% RDN through Vermicompost) produce5d maximum number of siliquae (201.62), seeds per siliqua (11.87), seed yield (1450 kg ha-1), stover yield (2848 kg ha-1) and biological yield (4413 kg ha-1) which were in statistical terms, at par with treatment T3 (50% RDF + 50% RDN through FYM). The influence of different integrated plant nutrient management, treatment T2 (50% RDF + 50% RDN through Vermicompost) showed maximum value of gross returns (90,953 Rs ha-1). However, in terms of net returns (51,041 Rs ha-1) and benefit cost ratio (2.53), T1(RDF 100%) exhibit the greatest values. Furthermore, the control plots showed least values over other treatments at all the observation stages of the experiment.
