Abstract:
Present experiment was carried during 2021-22 at Horticulture Research Block, School of Agriculture Sciences, SGRRU, Dehradun, Uttarakhand to find out the “Efficacy of organic manure and biofertilizer concentration on growth, yield and economics of Coriander (Coriandrum sativum L.) under Dehradun Valley of Uttarakhand”. The experiment was laid out in randomized block design with three replications and ten treatments. The treatments comprised following levels of different organic manures with different concentrations viz. T₁ (Control), T₂ (Vermicompost@ 5t/ha), T₃ (FYM@ 10t/ha), T₄ (Vermiwash @ 50%), T₅ (Cow urine @ 50%), T₆ (Rhizobium @ 500ml/ha), T₇ (VC @ 2.5t/ha + FYM @ 5t/ha), T₈ (VC @ 2.5t/ha + FYM @ 5t/ha + Vermiwash 25%), T₉ (VC @ 2.5t/ha + FYM @ 5t/ha + Vermiwash 25% + Cow urine 25%) and T₁₀ (VC @ 2.5t/ha + FYM @ 5t/ha + Vermiwash @ 25% + Cow urine @ 25% + Rhizobium 250ml/ha). The sowing of coriander cultivar “Italian Hero” was done on 27/11/2021. The first harvesting of leaf was done at 15/01/22 and final harvest at 05/04/2021. Observations on various attributes viz. growth, yield and economics were recorded at 30, 60 DAS and at final harvest. The results revealed that treatment T₁₀ (VC @ 2.5t/ha + FYM @ 5t/ha + Vermiwash @ 25% + Cow urine @ 25% + Rhizobium @250ml/ha) was found to be most effective in terms of growth characters such as number of leaves (11), plant height (16.58cm), leaf Length (2.81cm), fresh weight of per plant (6.55g), fresh weight of leaves (6.07), dry weight of leaves (2.41g), root length (6.95cm), leaf yield g/plot (810g), leaf yield kg/plot (0.810Kg), leaf yield t/ha (8.1 t/ha ) and T₉ (VC @ 2.5t/ha + FYM
