ThesisItem Open Access EFFECT OF DIFFERENT FERTILIZER LEVELS ON PRODUCTIVITY AND PROFITABILITY OF LITTLE MILLET (Panicum sumatrense Roth ex Roem. & Schult)(University of Agricultural & Horticultural Sciences, Shivamogga, 2017-07-14) DIVYASHREE, U; D.r DINESHKUMAR, M; Dr. SRIDHARA. SA field experiment was conducted during 2016-17 at Agronomy field unit, UAHS, Shivamoggga. The experiment was laid out in Randomized Complete Block Design with twelve treatments replicated thrice. The soil of the experimental site was acidic in reaction, low in available nitrogen, high in available phosphorus and medium in available potassium status. The test variety was Hiriyur local. The treatments comprised of combinations of three levels of nitrogen (10, 20 and 30 kg N ha-1), two levels of phosphorus (10 and 20 kg P ha-1), and two levels of potassium (0 and 10 kg K ha-1). Among the different combinations of NPK fertilizers tested, application of 30 kg nitrogen and 20 kg phosphorus with or without 10 kg K ha-1 performed better. However, 30:20:10 kg NPK ha-1 recorded significantly taller plants (71.27 cm), higher number of leaves (40.87 plant-1), number of tillers (10.87 plant-1), leaf area (514.59 cm2 plant-1), total dry matter accumulation (24.25 g plant-1), number of productive tillers plant-1 (9.4), panicle length (13.43 cm), number of grains panicle-1 (592), test weight (3.39 g), grain yield (1580 kg ha-1) and straw yield (1603 kg ha-1). Higher total uptake of Nitrogen (35.48 kg ha-1), Phosphorus (13.23 kg ha-1), Potassium (25.01 kg ha-1) was also recorded in the same treatment. The agronomic nutrient use efficiency of N, P and K was found higher in the treatment supplied with 30:20:10 kg NPK ha-1 (4.37, 7.31 and 8.09 kg grain kg-1 nutrient applied respectively) and recovery efficiencies were also found higher. Higher gross returns (` 87,015), cost of cultivation (` 47,118), net returns (` 39,897), B : C (1.85) was recorded in the treatment supplied with 30:20:10 kg NPK ha-1 and found better for light soils.
