Abstract
A field experiment entitled “Site specific nutrient management based on STCR in safflower (Carthamus tinctorius l.)” was conducted during the rabi season of 2017-18 and 2018-19 at Research Farm, Department of Agronomy, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola. Experimental plot was clayey in texture with medium in organic carbon (0.59%), low in nitrogen (194 kg ha-1), medium in phosphorus (26.10kg ha-1),fairly high amount of potash (325 kg ha-1) and slightly alkaline in nature. The soil was medium deep black belonging to Vertisols. The experiment was laid out in factorial randomized block design replicated four times. The factor ‘A’ consisted of three manure application treatments i.e. M0- no manure, M1 - 5 t FYM ha-1 and M2 - greengram residue incorporation. while the factor ‘B’ consisted of five nutrient management treatments viz., F0- control (no fertilizer), F1 - recommended NPK, F2 - SSNM (STCR equation), F3 - SSNM (STCR equation) + (ZnSO4 @ 25 kg ha-1+ S @ 10 kg ha-1)and F4 - SSNM (NPK) (deficient + 25 % rec.; Medium: rec.; high: -25 % rec.) with fifteen treatment combination. Objective of study was to evaluate the manure application, nutrient management treatments and their interaction effect on growth, yield, quality, nutrient uptake and economics of rabi safflower.Crop variety used in the present investigation was AKS-207. This variety has been evolved by AICRP safflower Centre, Dr. P.D.K.V. Akola. This variety has suitable for Vidarbha region of Maharashtra.
