ABSTRACT
Field experiments were conducted during 2014 atAgriculture College, Navile, University of Agricultural and Horticultural Sciences, (UAHS) Shivamogga during Kharif 2014, to study the effect of zinc fortified organic manures on yield, quality and nutrient uptake in rainfed maize. The experiment consisted of 12 treatments was laid out in Randomized Complete Block Design (RCBD) and replicated thrice. The treatments comprise of zinc fertilization through zinc enriched maize residue compost, FYM, soil and foliar means were compared with recommended dose of fertilizer alone and recommend package of practice. In the present experiment significantly higher grain (60.9 q ha-1) and stover yields (62.57 q ha-1) was recorded with application of 7.5 t of Maize Residue Compost (MRC) enriched with 15 kg ZnSO4 on account of significantly higher test weight (31.51 g) and grain yield plant-1 (134.7 g plant-1). Again, total dry matter production (326.38 g plant-1) and uptake of nitrogen (124.11 kg ha-1), phosphorous (24.87 kg ha-1), potassium (149.36 kg ha-1) and zinc (451.51 g ha-1) were also significantly higher with application of 7.5 t of Maize Residue Compost enriched with 15 kg ZnSO4. With regards to quality parameters of maize significantly higher grain zinc content (46.67 mg kg-1), soluble protein in grain(5.39 mg kg-1), crude protein content (12.67 %) and protein yield (760.14 kg ha-1) of maize was also higher with application of 7.5 t of Maize Residue Compost enriched with 15 kg ZnSO4.
Key words: Biofortification, Enriched MRC, Foliar Application, Uptake, Quality, Zinc.
