Background: Canola is an important oilseed crop throughout the world which is grown in more than 53 countries. Proper nutrient management plays a key role in its production. Use of unbalanced and inadequate fertilizers accompanied by restricted use of organic manures resulting in a decline in crop yield and quality. Little information is available on the response of canola to these factors. Therefore, this study is focused on to evaluate effect of foliar application of sulphur and integrated nutrient management on canola.Methods: A field experiment was conducted on sandy loam soil during winter (Rabi) season of 2017-18 and 2018-19 at Student’s Research Farm, Khalsa college, Amritsar to study the effect of foliar application of sulphur and integrated nutrient management on yield, quality and economics of bed transplanted canola (Brassica napus L.). Canola variety GSC 7 was sown by transplanting method on beds at spacing of 30 cm × 10 cm under Randomized Complete Block Design (RCBD) with 6 treatment combinations of organic (Vermicompost and pressmud), inorganic and foliar fertilizer were used under three replications. Result: The results revealed that treatment containing 100% RDF + 40 kgha-1 sulphur + 1% foliar sulphur spray (T2) led to maximum siliqua length (8.5 cm), no. of siliqua plant-1 (547.5), no. of seed siliqua-1 (28.8), test weight (4.64 g), seed yield (24.92 q ha-1) and stover yield (78.53 q ha-1) whereas treatment consisting 100% N through vermicompost + 40 kgha-1 sulphur + 1% foliar sulphur spray (T3) led to highest quality attributes i.e. oil content (43.73%), protein content (30.8%) in seed which was at par with 100% N through pressmud + 40 kgha-1 S + 1% foliar sulphur spray (T4) which also resulted highest sulphur content (0.48%) in seed. The maximum gross return (Rs. 104664 ha-1), net return (Rs. 59049 ha-1) and benefit cost rato (1.29) obtained from treatment containing 100% RDF + 40 kgh-1 sulphur + 1% foliar sulphur spray (T2). It was observed that foliar application of sulphur enhanced the yield whereas application of organic manures improved the quality of canola.

A field study was carried out during rabi seasons in 2017-18 and 2018-19 after harvest of rice to reveal the residual effect of integrated nutrient management on nodulation, yield, quality and available nutrient status in soil after harvest of greengram at Instructional Farm of College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar. The maximum number of root nodules/plant at 30 DAS and 45 DAS in greengram (5.86, 6.19 and 12.49 and 12.94in 2017 and 2018 respectively) were recorded in the subplot treatment of 75% RDF+ rhizobium + PSB and lowest values were obtained in 75% RDF treatment. Similarly in main plot, residual effect of 50% RDF+50% RDN through FYM showed significantly higher number of root nodules/plant during both the years of study which remained at par with 75 % RDF+ Green manuring. Lowest values were obtained from only RDF treatment. Residual effect of 50 % RDF+50 % RDN through FYM showed significantly higher protein % (24.2 and 24) and protein yield (194.3 and 196.2) during both the years of study which remained at par with 75 % RDF+ Green manuring treatment. Residual effect of 75 % RDF+ Green manuring treatment recorded higher increase in soil organic carbon (4.87 g/kg), available N(225.7 kg/ha), Available P (26.2 kg/ha) and available K (296.0 kg/ha) than all other treatment combinations. The residual treatment 50% RDF+25% RDN through FYM recorded the lowest values of soil nutrient status after harvest of greengram. Similarly the sub plot treatment receiving 75% RDF+ Rhizobium+ PSB recorded significantly higher soil organic carbon (4.67 g/kg), available N(217.1 kg/ha), Available P (22.8 kg/ha) and available K (291.8 kg/ha) than 100% RDF and 75% RDF.

Safed Musli

The field experiment was conducted during 2013-2014 at Nagarjuna Medicinal Plants Garden, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (M.S.) There were three levels of FYM and four levels of fly ash with three replications in FRBD on Inceptisol with a view to study the effect of FYM and fly ash application on yield, quality and nutrient uptake of safed musli. As the physiological maturity of the crop begins at 85-90 days after sowing (DAS) the growth observations e.g. number of leaves, leaf area were recorded at 30, 60 and 90 days after sowing. The number of leaves were successively increased with each growth stage upto 60 days Significantly highest leaf area was recorded with the application of 20 t FYM ha-1 (M2) .Significantly highest leaf area (29.56 cm2) was recorded at 60 DAP with the application of 15 t fly ash ha- 1 which was at par with 10 t fly ash ha-1 (F2) and 5 t fly ash ha-1 (F1). Significantly highest dry matter accumulation was recorded with the application of 20 t FYM ha-1, however, it was at par with 10 t FYM ha-1. The highest biomass accumulation was observed with 15 t fly ash ha-1 (F3) which was at par with 10 t fly ash ha-1 (F2) and 5 t fly ash ha-1 (F1). The thermal industrial waste like fly ash showed a promising option for nutrient management in medicinal crop plant like safed musli which can substitute to some extent costly chemical fertilizer and improve the qualitative value of safed musli.
