Growth and Yield Performance of Soybean (Glycine max L. Merril) Varieties Under Rainfed Condition of Nagaland

摘要

The field experiment was conducted during kharif season of 2015, with seven soybean varieties viz., MACS -1614, SL-982, DS - 2705, MAUS - 612, JS - 20-69, RKS -19 and JS- 9752, to study the growth and yield performance of different soybean varieties and also to identify the best soybean variety suitable for the agro-climatic condition of Nagaland. The results revealed that there was a significant difference among all the soybean varieties for all the growth and yield parameters studied. Among the seven soybean varieties, JS- 9752 appeared by and large the most suitable for the agro-climatic conditions of Nagaland. This variety gave significantly higher plant height (61.08 cm), number of leaves per plant (25.35), shoot dry weight (27.90 g plant~(-1)), leaf area index (1.50), crop growth rate (28.78 g m~2 day~(-1)), number of nodules per plant (71.33), pods per plant (62.13), number of seeds per pod (2.25), test weight (145.35 g), grain yield (2.711 ha~(-1)) and stover yield (3.48 t ha ~(-1)) respectively.
