Growth and production of three rice varieties (Oryza sativa L.) in saline stress condition following halopriming and hydropriming treatment

Abstract

Abstract Research to study the growth and production of three rice varieties treated with halopriming and hydropriming in saline stress condition has been carried out. This study aimed to determine the growth of three rice varieties on salinity stress by applying seed priming technology using halopriming agents. The research was conducted at the Laboratory of Plant Breeding and Seed Sciences, Department of Agronomy, Faculty of Agriculture and on the Rice Research and Demonstration Field Universitas Hasanuddin, Makassar. This study employed a split plot design with varieties as the main plot and halopriming agent as subplot; each repeated three times. The results show that the Membramo variety compared to Banyuasin and Inpari 7 varieties, showed the best results on length of panicle (23.16 cm), number of grain per panicle (140.88 grains), and weight of 100 seeds (3.94 g), production per plant (10.42 g) and production per hectare (3.45 tons ha−1). The use of NaCl as halopriming agent showed the best effect on the number of grain per panicle (131.31 grains). Whereas table salt used as halopriming agent resulted in the best effect on the production per plant (10.27 grams).
