The experiment was laid out in factorial randomized block design with additional treatment and replicated thrice. The factor A consists of three different types of herbal kunapajala concoctions viz., nettle grass based (KJ1), common weeds based (KJ2) and 50% nettle grass + 50% common weeds (KJ3). Whereas, factor B consists of four doses viz., 500 l/ha (D1), 1000 l/ha (D2), 1500 l/ha (D3) and 2000 l/ha (D4). In additional treatment, 100% recommended package and practices (NPKS) were taken. The plant height and dry matter accumulation resulted significantly more in KJ1 and D4 at various growth stages. Among control versus rest treatments, more plant height and dry matter accumulation was resulted in control treatment except plant height during second year. Similarly, more number of branches, total chlorophyll, carotenoid, SPAD and NDVI at various growth stages was resulted more in KJ1 and D4. Between control versus rest treatments, Control treatment resulted more total chlorophyll, carotenoid, SPAD and NDVI during first year and in second year SPAD and NDVI were resulted more in rest treatment. The yield attributing characters were resulted more in KJ1 and D4 during both years among herbal kunapajala concoctions and their doses. Whereas, control treatment resulted more yield attributing characters during both years. The significantly more crop yields were resulted with KJ1 and D4 during both years. Across control versus rest treatment, more crop yields were observed in control treatment during both years. The protein and oil content were resulted more in KJ1 and D4. Whereas, rest treatment resulted more protein and oil content. Low erucic and high glucosinolate values were observed in KJ2, KJ1 and D1, D4, respectively. Among control versus rest, control treatment resulted low erucic and rest treatment resulted high glucosinolate content. The rest treatment showed better soil properties in comparison with control treatment after two years of experimentation. The better economics was observed in KJ1 and D4. Similarly, rest treatment showed better economics in comparison with ontrol treatment. Based on the results obtained, application of nettle based herbal kunapajala with 2000 l/ha along with basal application of ganjeevamrutha and 10% foliar spray showed better growth, yield attributes, crop yields and economics in Indian mustard.EnglishThesis
