Response of NPK and Organic Manures on Quality and Commercial Yield of Carrot (Daucus carota l.) cv. Nantes

A field study was conducted on the Experimental Unit, Department of Horticulture, Tilak Dhari Post Graduate College, Jaunpur during rabi season year 2017-18 in to study the response of NPK and organic manures on quality and commercial yield of carrot (Daucus carota L.) cv. Nantes. The seed of carrot were sown in the mid November with a spacing of 30×10 cm. The experiment was laid out in Randomized Block Design with twelve treatments replicated thrice. Among the minimum root forking (5.25%) was recorded in the treatment T5 (75%NPK+PM), while maximum root forking (8.47%) was noted under the treatment T7 (50%NPK+VC). The root cracking percentage lied between 0.67 to 3.46%. The minimum root cracking (0.67%) was recorded under the treatment T9 (25%NPK+FYM). However, the maximum root cracking (3.46%) was observed in the treatment T1 (control). Highest total soluble solid (9.720Brix) was determined with treatment T4 (75%NPK+VC) while lowest total soluble solid (7.340Brix) was found in treatment T1 (control). Statistical analysis revealed that treatment T4 (75%NPK+VC) has increases the maximum ascorbic acid (6.02 mg/100g) while the minimum ascorbic acid (5.02 mg/100g) were found in treatment T1 (control). Maximum yield/plot (2.32 kg) and maximum yield/ha (232.20 qt) was recorded in treatment T4 (75%NPK+VC) while minimum yield/plot (0.80 kg) and minimum yield/ha (0.80) was found in T1 (control). Benefit cost ratio maximum (15.20:1) is found in treatment T4 (75%NPK+VC) and maximum net income (871070) was found in T4 (75%NPK+VC).
