Comprehensive evaluation of coriander (Coriandrum sativum) varieties under different organic modules

An experiment was conducted for the evaluation of coriander (Coriandrum sativum L.) varieties under different organic modules for sustainable production during rabi season of 2009-10 to 2012-13 (four years) at ICAR- National Research Center on Seed Spices, Tabiji, Ajmer, Rajasthan. The experiment was laid out in Factorial Randomized Block Design consisting of three organic modules (M1, M2 and M3) and two varieties Ajmer Coriander-1 (ACr-1, V1) and Rajasthan Coriander-41 (RCr-41, V2) with four replications. Findings of this study showed significant differences among the performance of different organic modules tested for two coriander varieties. Organic module M1 [comprising soil application of vermicompost (5 tonnes/ha), foliar spray of garlic extract (5% @ 2.0 kg/ha) + neem oil (2% @ 5 l/ ha, soil application of neem cake (150 kg/ha) and Trichoderma (2.5 kg/ha), seed treatment with Rhizobium (100 ml/kg seed), PSB (100 ml/kg seed) and Trichoderma (10 g/kg seed)] exhibited maximum number of primary branches (8.05/ plant), secondary branches (21.88/ plant), number of umbels (32.22/ plant), number of seeds (8.81/ umbellate) and highest seed yield (1323.90 kg/ha) in coriander crop. Similarly, significant differences were recorded in the performance of coriander varieties under different organic modules and the maximum number of primary branches (7.87/ plant), secondary branches (21.55/ plant), number of umbels (29.20/ plant), number of umbellates (5.81/ plant) and number of seeds (8.40/ umbellate) with earliest flowering (66.05 days after sowing-DAS), and highest seed yield (1296.31 kg/ ha) were recorded in coriander variety ACr-1 than that of variety RCr-41. Cultivation of coriander variety ACr-1 with the application of Module-1 exhibited maximum values for all the growth parameters, yield attributing characters with maximum seed yield. Hence, variety ACr-1 is suggested to grow organically with the application of Module-1 (M1) under semi-arid environmental conditions.
