Response of NPK and organic manures on growth and yield of carrot (lt;emgt;Daucus carota lt;/emgt;L.) CV. Nantes

Abstract

A field study was investigated on the Experimental Unit, Department of Horticulture, Tilak Dhari Post Graduate College, Jaunpur during 2017-18 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. The maximum height of plant (95.14cm) at 40, 60, 80 DAS was observed with the application of 100%NPK (T2) and minimum (79.39cm) was found under control treatment (T1) i.e. without application of fertilizer. The maximum length of leaves (65.39cm) was observed with the application 100%NPK (T2) and minimum (58.01cm) was found under control treatment (T1) i.e. without application of fertilizer. The maximum number of leaves per plant (22.00) was observed with the application of 100%NPK (T2) and minimum (16.33) was found under control treatment (T1) i.e. without application of fertilizers. The maximum fresh weight of leaves per plant (132.15g) was observed with the application of 75%NPK+VC (T4) and minimum (119g) was found under control treatment (T1) i.e. without application of fertilizers. The maximum fresh weight of plant (g) (200.13g) was observed with the application of 100% NPK (T2) and (170.33g) was found under control treatment (T1) i.e. without application of fertilizers. The maximum dry weight of plant (g) (30.24g) was observed with the application of 100%NPK (T2) and minimum (27.13g) was observed under control treatment (T1) i.e. without application of fertilizers. Application of 75%NPK+VC (T4) recorded maximum length of root (28.64 cm) while it was minimum (21.62cm) under the control treatment (T1) i.e. without application of fertilizers. The maximum diameter of root (5.44cm) was recorded with the application of 75%NPK+VC (T4) while it was minimum (3.33 cm)was observed under control treatment (T1) i.e. without application of fertilizers. The maximum fresh weight of root (122.93g) was recorded with the application of 75%NPK+VC (T4) while it was minimum (102.86g)was observed under control treatment (T1) i.e. without application of fertilizers. The maximum dry weight of root (9.65g) was recorded with the application of 75%NPK+VC (T4) while it was minimum (4.94)was observed under control treatment (T1) i.e. without application of fertilizers. Highest root yield) (2.32 kg/plot) was observed with the application of 75%NPK+VC (T4 ) while it was lowest (0.80 kg/plot) was observed under control treatment (T1) i.e. without application of fertilizers. Highest root yield (232.21 q/ha) was observed with the application of 75%NPK+VC (T4) while it was lowest (80 q/ha) was observed under control treatment (T1) i.e. without application of fertilizers.
