Response of crop geometry, fertilizer application and genotypes on growth, yield and yield attributes in coriander (Coriandrum sativum L.)

A field experiment was conducted during Rabi 2020-21 and 2021-22 at KVK, Guna.Treatments comprised of three crop geometry viz., 20x10 cm (S1), 22.5x10 cm (S2) and 25x10cm (S3), two fertilizer levels viz., F1 -60:40:40:20 N:P:K:S ha-1, F2- 70:50:50:30 N:P:K:S ha-1 and three genotypes viz., Ajmer Coriander-1 (V1), Pant Haritima (V2) and Kumbhraj as a check (V3). The experiment was laid out in Randomized Block Design (RBD) with factorial concept. Result revealed that application of N:P:K:S 70:50:50:30 (F2) Kg- 1 ha with a row spacing of 25x10 cm (S3) row spacing significantly improved plant height, number of branches/plant, while minimum days to 50% flowering was recorded in 20x10cm (S1), whereas the highest number of umbels/plant, test weight (g), Umbellates Plant-1, seed yield (kg ha-1), straw yield (kg ha-1), biological yield (kg ha-1), harvest index (%) was recorded in 25x10 cm (S3) Highest No. of nodes (11.20, 11.08 and 11.28) at harvest in S3, F2 and V2 and primary branches were recorded (8.86, 8.65 and 8.58) in S3, F2 and V2, respectively for growth parameters whereas, maximum No. of umbels and No. of umbellates (39.26, 38.20, 42.39 and 139.91, 134.66, 140.82) was recorded at harvest in S3, F2 and V2, respectively. Maximum seed yield (13.22, 12.62, 12.80 and 25.77, 24.57, 24.76) was recorded in S3, F2 and V2, respectively (kg ha-1). Pant Haritima (V2) recorded an additional net returns of Rs. 89273 and Rs. 82510 over Kumbhraj (V3) and Ajmer Coriander-1 (V1). Highest B:C ratio was obtained with Pant Haritima (3.36) as compared to Kumbhraj (3.34) and Ajmer Coriander-1 (2.93), respectively.
