Growth, yield and essential oil of coriander (Coriandrum sativum L.) variety ACr-2 as influenced by various nutrient levels and crop geometry

Abstract

A field experiment was carried out Rabi season of 2017-18 at research farm of ICAR-NRCSS, Ajmer, Rajasthan to study the growth, yield and essential oil characterization of coriander variety Ajmer Coriander-2 (ACr-2) as influenced by nutrient levels and crop geometry. The experiment was laid out in Factorial Randomized Block Design with four replications. The experiment was comprises three treatment of each crop geometry and nutrient management. Crop geometry G1 (30 cm x 15 cm), G2 (30 cm x 10 cm) and G3 (30 cm x 5 cm) with nutrient levels N, P2O5 and K2O of kg/haF1 (40:20:10), F2 (50:25:15) and F3 (60:30:20). The results revealed that the maximum plant height (91.38 cm), primary branches per plant (10.90) and secondary branches per plant (13.28) were recorded with application of 60:30:20 kg/ha NPK and crop geometry of 30 cm x 10 cm. Similar trends were found in yield attributes like number of umbel per plant (34.09) and number of umbellates per umbel (5.91). Seed yield per hectare (1271.25 kg/ha) and essential oil yield (6.74 kg/ha) was also observed with application of 60:30:20 kg/ha NPK with crop geometry of 30 cm x 10 cm. Based on the results it is concluded that nutritional level of 60:30:20 kg/ha NPK with crop geometry of 30 cm x 10 cm is better for realizing higher seed yields of coriander variety ACr-2.
