Pengaruh Cekaman Kekeringan terhadap Produktivitas Kedelai (Glyicine max (L.)Merril.) Hasil Radiasi Ultraviolet

Abstract

The effect of drought stress to soybean productivity has been done in Genetic Laboratory, Natural Sciences Faculty and green house at Agriculture Faculty, University of Sumatera Utara, Medan. The experiment design was used complete factorial randomized with 2 factors. The first factor is type of seed: normal seed and seed after ultraviolet radiation 10 watt 10 minutes, the second factor is field capacity: 100, 75, 50, and 25%. The result of the experiment shows that different of water capacity caused significant different to the plant height, number of flower, dry weight seed, and dry weight of plant. The best result obtained in soybean after ultraviolet radiation in highly drought stress that is in 25% field capacity.
