Effect of Genotypes, Fertilizer Application & Crop Geometry on Growth, Yield and Yield Attributes in Coriander (Coriandrum sativum L.)

Abstract

A field experiment was conducted during rabi 2019-20 & 2020-21 at KNK Horticulture College. Treatments comprised of three crop geometry viz., 20x10 cm (S1), 25x10 cm (S2) and 30x10cm (S3), two fertilizer levels viz., F145:35:35:20 N:P:K:S ha-1, F260:45:45:30 N:P:K:S ha-1 and three genotypes viz., Rcr 41 (V1), Ajmer Coriander ACr-2 (V2) and Pant Haritima as a check (V3). The experiment was laidout in Randomized Block Design (RBD) with factorial concept. Result revealed that application of N:P:K:S 60:45:45:30 (F2) Kg-1 ha with a row spacing of 30x10 cm (S3) 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 30x10 cm(S3) Highest No. of nodes (11.20, 11.08 & 11.28) at harvest in S3, F2and V2and primary branches were recorded (8.86, 8.65 & 8.58) in S3, F2 and V2 respectively for growth parameters whereas, maximum No. of umbels and No. of umbellate (39.26,38.20,42.39&139.91,134.66,140.82 )was recorded at harvest  inS3,F2and V2 respectively. Maximum Seed yield (13.22, 12.62, 12.80 & 25.77, 24.57, 24.76) was recorded in S3, F2and V2 respectively (kg ha-1). Ajmer Coriander ACr-1 (V2) recorded an additional net returns of Rs. 89273 and Rs. 82510 over Pant Haritima (V3) and Rcr 41 (V1). Highest B:C ratio was obtained with Ajmer Coriander ACr-1(3.36) as compared to Pant Haritima (3.34) and Rcr 41 (2.93) respectively.
