Abstract:
A field experiment entitled “Effect of Organic Manure and Fertilizers on Productivity and Nutritional quality of Mustard (Brassica juncea L.)” was carried out during rabi, 2022-23 at Experimental Farm, Department of Agronomy, School of Agricultural Sciences, Dr. K. N. Modi University, Newai Rajasthan. The soil was sandy loam in texture, slightly alkaline in reaction, low in available nitrogen, medium in organic carbon, medium in available phosphorus and high in available potassium. The experiment was carried out with 9 treatments viz., Control (100% RDF -80:40:40 kg NPK ha^-1) (T₁), 25% RDN through Farm Yard Manure + 75% RDF (T₂), 25% RDN through Vermicompost + 75% RDF (T₃), 25% RDN through Sheep manure + 75% RDF (T₄), 25% RDN through Neem cake + 75% RDF (T₅), 50% RDN through FYM + 50% RDF (T₆), 50% RDN through Vermicompost + 50% RDF (T₇), 50% RDN through Sheep manure + 50% RDF (T₈), 50% RDN through Neem cake + 50% RDF(T9), laid out in randomized block design, replicated thrice. application of 25% RDN through vermicompost + 75% RDF (T₃) had shown significantly higher plant height, leaf area index compared to rest of treatments and was statistically at par with 25% RDN through FYM + 75% RDF (T₂). Application of 25% RDN through vermicompost + 75% RDF (T₃) had shown significantly higher number of branches plant^-1, dry matter production, number of siliqua plant^-1, length of siliqua, number of seed siliqua^-1 and test weight which was superior to rest of treatments and was at par with 25% RDN through FYM + 75% RDF (T₂).The highest seed yield, stover yield, oil content and protein content were observed with application of 25% RDN through vermicompost + 75% RDF (T₃) compared to all remaining treatments and control (100% RDF) and it was at par with 25% RDN through FYM + 75% RDF (T₂). Higher nutrient uptake (N, P and K) was observed with 25% RDN through vermicompost + 75% RDF (T₃) compared to other treatments and it was statistically at par with 25% RDN through FYM + 75% RDF (T₂). The higher values of gross returns, net returns and benefit cost (B:C) ratio was obtained with application of 25% RDN through vermicompost + 75% RDF (T₃). Based on the above results, it can be concluded that application of 25% RDN through vermicompost + 75% RDF (T₃) enhanced the growth and yield of mustard and proved to be the most remunerative treatment.
