Abstract:
We evaluated the effects of KCl substitution by NaCl on the growth and nutrient level of upland rice an Ultisol during four months in Panca Budi Experimental Farm, Medan, Indonesia. The study used a two-factor randomized block design with three replications. The first factor is NaCl, consisting of 5 levels. namely: 0 mg NaCl/polybag; 118 mg NaCl/polybag; 235 mg NaCl/polybag; 350 mg NaCl/polybag and 470 mg NaCl/polybag. The second factor is KCl, consisting of 5 levels namely 0 mg KCl/polybag, 150 mg KCl/polybag, 300 mg KCl/polybag, 450 mg KCl/polybag and 600 mg KCl/polybag. The results showed that NaCl significantly increased the nutrient levels of N, P, Na, KCl also significantly increased the nutrients levels of N, P, K. However, NaCl and KCl applications did not increase the growth of upland rice. The effect of KCl substitution by NaCl to 100% (470 mg/polybag) did not decrease the growth and nutrient levels of the plant.
