Abstract
The present study was conducted at Post Graduate Institute, Research Farm, Department of Soil Science and Agricultural Chemistry, MPKV, Rahuri, during Kharif 2019. The experiment was laid out in a randomized block design with three replication and twelve treatments. The treatment comprised of T1: Absolute control, T2: Gypsum as per 100% GR, T3: Elemental sulphur as per 1/5th of GR, T4: Zeolite @ 600 kg ha-1, T5: Gypsum as per 100% GR + zeolite @ 600 kg ha-1, T6: Gypsum as per 50% GR + zeolite @ 600 kg ha-1, T7: Gypsum as per 100% GR + zeolite @ 300 kg ha-1, T8: Gypsum as per 50% GR + zeolite @ 300 kg ha-1, T9: Elemental sulphur as per 1/5th of GR + zeolite @ 600 kg ha-1, T10: Elemental sulphur as per 50% of 1/5th GR + zeolite @ 600 kg ha-1, T11: Elemental sulphur as per 1/5th of GR + zeolite @ 300 kg ha-1 and T12: Elemental sulphur as per 50% of 1/5th GR + zeolite @ 300 kg ha-1. The biomass production in maize crop grown on sodic soils under SSD (Subsurface drainage) field in terms of their fresh and dry matter yield mainly depends on uptake of nutrient and micronutrient by maize crop. Total uptake of nitrogen, phosphorus and potassium by maize crop were found to be higher (132.77, 27.14 and 134.46 kg ha-1, respectively) in treatment Gypsum as per 100% GR + zeolite @ 600 kg ha-1. Total uptake of iron, zinc, manganese and copper were found to be significantly higher (2034, 1134, 1443 and 805 g ha-1, respectively) in treatment Gypsum as per 100% GR + zeolite @ 600 kg ha-1. The grain and stover yield of maize was significantly highest recorded in treatment Gypsum as per 100% GR + zeolite @ 600 kg ha-1 (53.8 and 62.44 q ha-1). Therefore, based on above findings, application of Gypsum as per 100% GR + zeolite @ 600 kg ha-1 along with the FYM and general recommended dose of nutrients (10 t ha-1 FYM + 120:60:40, N:P2O5:K2O kg ha-1) to maize in SSD field was found beneficial for reclamation of sodic soil, increase in availability of nutrients in soil, total uptake of macro and micronutrients and higher grain and stover yield of maize grown in sodic soil under SSD system.
