Research on the growth, development, and yield of some drought-tolerant rice varieties

Abstract

This research used ten rice varieties which were collected in different sources in order to estimate their growth, development, drought tolerance, and yield. The experiment was designed in the randomized complete block (RCB), three replications for each variety. The research targets were implemented in accordance with the rice research regulation. The results showed that the two varieties OM4900 and IR93340 have a short growing time of 92-97 days, good growth and development, the morphological characteristics and quality that were acceptable, the ability of drought tolerance, the rather high yields at 56.00 quintals per hectare in OM4900 and 56.33 quintals per hectare in IR93340.
