Abstract: Areas of tail end of Visveswaraya Canal area indicated that soils are sandy clay in nature, alkaline in reaction (pH 7.61-8.20) with EC in the range between 0.43 and 1.1 dS/m. Soils were low organic carbon, medium nitrogen, high phosphorus, low potassium, high calcium, magnesium, sulphur and micronutrients. Sodium ion ranged between 0.85-0.98 and exchangeable sodium percentage (ESP) 4.40-6.10.
Field experiment were conducted during kharif season 2017 at farmers field in Hemmnahalli village, Maddur taluk, Mandya district to assess the growth and yield response to organic and inorganic amendments to alkaline soil. The experiment were laid out in a randomized complete block design with nine treatment combinations and replicated thrice. The results revealed that the application of 100% NPK+ Green manure+ ZnSO4+ Gypsum+ FYM recorded significantly higher grain (6266 kg/ha) and straw (6892 kg/ha) yield of rice, nutrient content and uptake as compared to other treatment. Further higher primary, secondary and micronutrient status in soil and decreased pH, EC, Na and ESP were recorded in the same treatment.
The study clearly showed that in alkaline soils, application of 100% NPK+ Green manure+ ZnSO4+ Gypsum+ FYM is more beneficial in enhancing the crop yield, crop productivity as well as fertility of the soil.
