Abstract

One of the problems encountered by coastal sandy land is the high concentration of salt which can cause limited water uptake, and ion poisoning to the plants. Silica is potential nutrient to solve salinity problem in coastal sandy land. The objectives of this experiment are to examine the effect of salinity conditions on the growth and yield of shallots in an Entisol. The study was conducted from August to November 2020 in the screen house of the Faculty of Agriculture and the Laboratory of Agronomy and Horticulture, Faculty of Agriculture, Jenderal Soedirman University. The experimental design used was a factorial randomized block design (RBD) 4 × 3 with three replications. Fertilizer Si consisted of 4 levels i.e. control or 0 g Si/pot; 10 g Si/pot, 20 g Si/pot, and 30 g Si/pot. The salinity (K) comprised 3 levels of dose: control; 2 dS/m/pot, and 4 dS/m/pot. There were 12 treatment combinations with 3 replications (36 experimental units). Each experimental unit was planted with 2 plants. The observed variables were plant height, number of leaves, fresh root weight, dry root weight, number of tillers, root volume, number of bulb, bulb diameter, fresh bulb weight, dry bulb weight. The results showed that the application of natural silica increases the number of leaves, the number of tillers and the number of bulb with an optimal dose of 11 g per plant. The increased level of salt reduced the weight of fresh roots, the number of tillers, the weight of fresh bulb, the weight of dry bulb, the number of bulb, and the diameter of the bulb. The effect of combination of Si fertilizer and salinity condition was found on the number of leaves, dry root weight, root volume and number of tillers.
