Abstract

Sawo is a tropical native fruit from Indonesia, demand fot the fruit of sawo is increasing every year, one of the most effective ways to consumer demand is to vegetatif propagation that is top grafting. Top grafting can be accelerated by the addition of plant growth regulators. The purpose of this research was to know the success of top grafting of sawo plants at various sizes of diameter plant seedling and levels of BAP concentration. The method used was factorial complete randomized design with 2 factor,the first factor was diameter plant seedling (small, medium and big) and the second factor was concentrations of BAP (0, 100 and 200 ppm) with 5 replications. The result showed that diameter plant seedling small and medium gave a significant effect (P<0.05) on time of shoot, number of leaf and long of shoot. The levels of BAP concentration 100 and 200 ppm gave a significant effect on the time of shoot, number of shoot and long of shoot and percentage of success. There is interaction of diameter seedling and concentration of BAP against top grafting of sawo varieties jumbo vietnam.

Abstract

Silica fertilizer is applied to the soil for the purpose of reducing the effects of salinity stress. This research study was conducted to examine the effect of fertilization ratio with different sources of silica to soybean growth and production on saline soil. The methods used was Completely Randomized Factorial Designs 2 x 6 with 3 replications. The first factor was soil salinity levels (A), consists of A1 (±3 dS/m) and A2 (±6 dS/m). The second factor was different silica fertilizer aplications (B) which consists of  B0 (without silica), B1 (100% zeolite), B2 (75% zeolite, 25% liquid silica), B3 (50% zeolite, 50 % liquid silica), B4 (25% zeolite, 75% liquid silica), and B5 (100% liquid silica). Parameters observed in this research were plant height, number of leaves, number of pods, pod weight, number of seed and seed weight. Data was analyzed by analysis of variance followed by Duncan's Multiple Range Test. The result showed that the application of silica fertilizer through soil and leaves (50% zeolite, 50 % liquid silica) improved the growth and yield of soybean on soil with moderately saline (3 dS/m). application of silica fertilizer (50% zeolite, 50 % liquid silica) improved the growth and yield of soybean. The higher soil salinity reduced soybean growth and yield. Moreover, the utilization of silica minimized the decrease in soybean growth and yield.
