Influence of Agronomic Fortification through Enriched Organics on Nutrient Uptake and Soil Chemical Properties in Foxtail Millet (Setaria italica L.) Cultivation under Organic Production System

摘要

Foxtail millet is a short-term catch crop which is drought tolerant. The potential yields are yet to be achieved due to its cultivation on marginal soils with less inputs use. The crop grown under organic system by enriching soil with organic manuresseems to be economically viable. Considering these points the experiment was conducted at Main Agricultural Research Station, Raichur, during kharif 2018 to study the effect of agronomic fortification through Zn and Fe enriched organics and foliar nutrition in foxtail millet (Setaria italica L.) cultivation. The design followed was randomized complete block design with three replications. Application of Zn and Fe enriched compost + foliar spray of panchagavya recorded significantly higher nitrogen, phosphorous, potassium, zinc and iron uptake (50.99,10.94,28.68,0.18 and 2.95 kg ha respectively). Similar results were found with soil available nutrients N, P, K and Fe (148.2, 80.3,797.9 and 14.21 kg ha~(-1), respectively) and electrical conductivity. Organic carbon and soil available Zn did not differ significantly but recorded highest values 0.21 d Sm~(-1), 0.64 per cent and 0.64 ppm, respectively.
