Interactive influences of different environmental conditions viz., ployhouse, shadenethouse and open field conditions and seasons of semi-arid tropics on functional performance of coriander (Coriandrum sativum L.) var. CO (CR)4

Abstract

The experiment is about the influence of season and cultivating environment on the growth and yield of coriander var. CO (CR)4. It was conducted at Institute of Agriculture, Tamil Nadu Agricultural University located at kumulur, trichy district of Tamilnadu. The experimental design was split plot design with 2 factors and three replications. Rabi season (October) recorded significantly maximum values in parameters such as germination percentage (63.36 %), plant height (27.18 cm), number of leaves per plant (36.16), plant height (6.76 g) and yield per hectare (7.29 t/ha) on comparing with kharif crop. Likewise coriander cultivated under polyhouse recorded maximum germination percentage (62.55 %), plant height (26.52 cm), number of branches (4.50), number of leaves per plant (36.40), plant height (7.57 g) and yield per hectare (7.99 t/ha) followed by shadenet house and open field condition. The interaction effect of season and growing condition has more influence especially in polyhouse condition during rabi season. The result of the experiment showed that cultivating coriander under polyhouse during kharif and rabi as well as under shadenet during rabi season will be cost effective and profitable.
