Effect of organic manures and micronutrients on seed production of carrot (Daucus carota L.)

The experiment was conducted during 2021-22 in rabi season. The field study to assess the effects of organic manures and micronutrients on seed production of carrot (Daucus carota L.) cv. Pusa Rudhira was carried out at Horticulture farm, SKNCOA, Jobner, Rajasthan, India. The study revealed that the application of Poultry manure @ 2.5 t/ha significantly increased the plant height (41.95 cm), Number of shoots per plant (12.71), chlorophyll content (1.11 mg/100g), days to 50% umbel initiation (134.50 days) , number of umbels per plant (17.30), number of seed per umbel (1177.35), diameter of umbel (16.71 cm), seed weight per plant (8.43 g), days to seed maturity (185.27 minimum days) and seed yield per hectare (6.24 q/ha). Similarly, the spray of ZnSO4 @ 0.5% to the carrot crop significantly increased the plant height (40.60 cm), number of shoots per plant (12.49), chlorophyll content (1.07 mg/100g), days to 50% umbel initiation (133.51 days), number of umbels per plant (16.30), number of seed per umbel (1175.30), diameter of umbel (16.10 cm), seed weight per plant (8.39 g), days to seed maturity (184.12 days ) and seed yield per hectare (6.21 q/ha)
