Influence of different rate of solid manure and types of liquid organics on yield, nutrient content and uptake of sweet corn under south Gujarat condition

A field experiment was conducted during rabi season of 2016-17 at Organic Farm (F block), Aspee College of Horticulture and Forestry Research Station, Navsari Agricultural University, Navsari Gujarat. The experiment was laid out in a Factorial Randomizes Block Design, comprising fifteen treatment combinations. The results indicated that application of 100% RDN through Nadep compost (O1) significantly increased green cob (15801 kg/ha) and fodder (19628 kg/ha) yield and was statistically on par with treatment O2 (75% RDN through Nadep compost). Similarly, significantly higher green cob (16145 kg/ha) and fodder (20068 kg/ha) yield were noted with application of Jeevamrut (L1) and remained at par with Panch gavya (L3) and Sanjeevak (L4) @ 600 L/ha, respectively. No significant effect of different levels of Nadep compost and liquid organics was observed on N, P, K, Fe, Mn, Zn and Cu content. Significantly higher individual as well as total uptake of N, P, K, Fe, Mn, Zn and Cu by sweet corn were noted with treatment O1 and L1, receiving 100% RDN through Nadep compost and Jeevamrut @ 600 L/ha, respectively.
