Effect of Tillage and Irrigation Methods on the Productivity, Profitability and Nutrient Uptake of Wheat

Abstract

Tillage and crop establishment method play an important role in the placement of seed at proper depth which ultimately affect germination and crop growth. The selection of suitable crop establishment method for wheat is dependent upon the time of sowing and availability of soil moisture. A field experiment was conducted during Rabi season 2017-18 and 2018-19 to evaluate the effect of tillage and crop establishment methods on productivity, nutrient uptake and profitability of wheat (Triticum aestivum L.). Results revealed that grains, straw and biological yields were significantly higher under treatment T5 (wide bed furrow irrigated) and at par with T2 (furrow irrigated with gated pipe Raised bed) and T8 (zero till flat irrigated by gated pipe Controlled flood irrigation).Total nitrogen, phosphorus and potassium uptake were significantly more in treatment T5 than other treatments. Significantly maximum gross return (97818 ₹ ha-1), was recorded under T5 which was at par with T8 and T2. The maximum net return (61910 ₹ ha-1) and B: C ratio (2.84) were fetched under T8 than all other treatments followed by and T5.
