EFFECT OF QUALITY PARAMETERS OF DESI COTTON AS INFLUENCED BY DIFFERENT NUTRIENT SOURCESV.V. Patil, A.V. Solanke, R.V. Mahajan, S.P. Wagh and N.D. GajbeAbstract A field investigation on âNutrient management for organic cotton (Gossypium arboreum L.) productionâ was carried out at All India Coordinated Research Project, Cotton Improvement Project, Research Farm, Mahatma Phule Krishi Vidyapeeth, Rahuri, Dist. Ahmednagar, Maharashtra (India) during kharif season of 2017 and 2018. The experiment was carried on the same site and same randomization of treatments during both the years. After these two year cycles, the quality parameters viz., ginning (%), micronaire value (mg inch-1), UHML (mm), bundle strength (g tex-1), uniformity index (%), elongation (%) were not much affected due to different organic and inorganic nutrient sources except the lint index. Significantly higher values of lint index were recorded with application of fertilizer through inorganic (80:40:40 N, P and K kg ha-1) to cotton. Among the organic nutrient sources, application of FYM based on P equivalent recorded maximum values of lint index followed by seed treatment with (Azotobactor+ PSB) + soil application of Azotobacter + PSB) and foliar application of PPFM (1% spray at 45 and 65 DAS) + neem cake 250 kg ha-1 + raising of sunnhemp between two rows (1:1) and incorporation in soil at flowering stage during both the years. |
