A field experiment was carried out on ‘Effect of integrated nutrient management on yield and quality of parching sorghum for identifying an ideal combination of Zinc, organic and inorganic nutrient sources for getting better quality, more net return and uptake of nutrients of kharif parching sorghum. The experiment was carried out at the farm of CRS, Sorghum Research Unit, Dr. PDKV, Akola, during Kharif season of 2016-17 on clayey loam soil. A Factorial Randomized Block Design was used for field experiment in which 12 treatment combinations were replicated thrice to evaluate treatment effect having three parching sorghum varieties. viz., V1-PKV Ashwini, V2-Malkapurwani (Local), V3-PDKV Kartiki and four nutrient management treatments viz., T1-10 t FYM /ha, T2-100% RDF (80:40:40) kg N, P2O5, and K2O /ha, T3-75% RDF + 5 t FYM /ha+ZnSO4 25 kg /ha, T4-100% RDF + ZnSO4 25 kg /ha. Among the varieties PDKV Kartiki (V3) recorded significantly higher gross monetary returns (Rs /ha), net monetary returns (Rs /ha), and B: C ratio. However, higher non reducing sugar content (%) and total sugar content (%) was recorded by PDKV Kartiki (V3) and PKV Ashwini (V1) recorded significantly lowest reducing sugar content (%). The total uptake of nutrients was maximum of Malkapur wani. However treatmentT1 10t FYM /ha is superior in case of reducing sugar content (0.40). Non reducing sugar content and total sugar content in grain was significantly maximum with application of 75% RDF + 5 t FYM /ha+ZnSO4 25 kg (T3), similarly total NPK uptake of grain and fodder was also significantly maximum with the same treatment. The, gross monetary returns, and net monetary returns were maximum with the same treatment. However benefit to cost ratio was maximum in 100% RDF inorganic+ZnSO4 25 kg /ha (T4). | Effect of integrated nutrient management on economics, sugar quality and uptake of parching sorghum genotypes
