Performance of Jobs tears lines (Coix lacryma-jobi) under foot hill condition of Nagaland

Abstract

An exploration and collection of jobstear germplasm was conducted in different district of Nagaland and a total of 10 accessions were collected, evaluated and conserved for documentation. The samples were in the form of jobster seeds with varying color and size. Keeping these in view, a field experiment was carried out during the pre- kharif season of 2015 to assess the best suitable high yielding line of jobstear to encourage and arouse the farmer’s interest in its commercial cultivation under the food hill condition of Nagaland. Experiment was laid out in completely randomized block design and replicated thrice. A total of 10 jobstear germplasm viz. JBN-1, JBN-2, JBN-3, JBN-4, JBN-5, JBN-6, JBN-7, JBN-8, JBN-9 and JBN-10 were collected from the farmers’ field across the different district viz. Jalukie, Kohima, Wokha, Zunheboto and Longleng of Nagaland was evaluated over here in terms of higher production potential under the rainfed condition. Results revealed that significant variations were observed in growth and yield attributes of jobstear lines. Among the tested lines of jobstear, JBN-10 line recorded the significantly higher yield attributes which led to higher grain yield as compared to other lines.
