Effect of planting geometry and nutrient management on yield and it’s attributing characters of coriander (Coriandrum sativum L.)
Aarti Tikariha and NK Choubey
A field experiment was conducted at Krishi Vigyan Kendra, Pahanda-A, Durg (C.G.) during the rabi seasons of 2022-23 and 2023-24. The study evaluated the effects of three planting geometries (G1-20 x 15 cm, G2- 30 x 10 cm and G3- 40 x 7.5 cm) and five nutrient management practices on coriander. The nutrient management practices included: N1-100% RDN (80, 60, and 40 kg of N, P2O5, and K2O ha-1), N2-125% RDN, N3-75% RDN + foliar spray of nano urea at 60 and 75 DAS, 100% RDN + foliar spray of nano urea at 60 and 75 DAS, N4 -100% RDN + foliar spray of nano urea at 60 and 75 DAS, and 100% RDN + foliar spray of nano urea at 60 and 75 DAS, N4- 100% RDN + foliar spray of nano urea at 60 and 75 DAS, N5 -100% RDN + foliar spray of water-soluble fertilizer (19:19:19) at 60 and 75 DAS. The experimental design was a split-plot with planting geometry as the main plot and nutrient management as the sub-plot. The results indicated that the 20 x 15 cm planting geometry achieved the highest yield attributes, including the number of umbels plant-1, umbellates umbel-1, seeds umbellate-1, 1000-seed weight, seed yield, stover yield, and economic values (Gross and net returns, and benefit-cost ratio) of coriander. The lowest values were observed with the 40 x 7.5 cm planting geometry. Among nutrient management practices, 100% RDN + foliar spray of water-soluble fertilizer (19:19:19) at 60 and 75 DAS recorded the maximum yield and its attributing characteristics of coriander. Conversely, the lowest values for these characteristics were recorded with 75% RDN + foliar spray of nano urea at 60 and 75 DAS.
