Pengujian model simulasi vigor kekuatan tumbuh benih kedelai (Glycine max L. Merril) pada lahan salin

Testing of Simulation Model of Soybean Seed Vigor Growth on Saline Soil ABSTRACT. The purpose of this research are to examine growth capability of 5 soybean varieties and to find out is laboratory seed testing model may be use to simulate the growth capability of soybean planted at soil with salinity problem. It is expected through this research obstacle in quick screening of plant growth at saline soil being solved. This research conducted from April – December 2011 at Seed Laboratory and Experimental Station of Agricultur Faculty of Unsyiah and farmer soil at Blang Krueng village, Aceh Besar. Experimental designs used in this research were Factorial CRD for laboratory and Factorial CRBD for field experiment. There are 5 varieties of soybean (Bener Meriah local seed, Kipas Merah, Kipas Putih, Anjasmoro and Orba) and 2 germination medium/soil (normal and saline) being examine, with 3 replicates, resulting 30 units experiments. Result from field experiments show that there is a significant interaction between soybean varieties and soil salinity level to seed growth capability. At normal soil, differences in varieties did not resulting in differences in seed growth capabilities, otherwise at saline soil. According to seed growth capabilities, at normal soil farmers can used any variety available, depends on production level. But, at saline soil farmers have to use Bener Meriah local seed. Whilst result from laboratory experiment did not show interaction of treatments to germination capability of soybean seed, but each treatment show its significant effect. Normal soil and Bener Meriah local seed are the best at laboratory experiment. The correlation test show that there is no close relationship between germination capability at laboratory and growth capability at field experiment, indicates that the method at laboratory cannot be use as a representative model to seed growth from field experiment
