Aplikasi Pupuk Organik dan Bakteri Pelarut Fosfat untuk Meningkatkan Pertumbuhan Tanaman Tomat dan Aktivitas Mikroba Tanah
The application of organic fertilizer and biofertilizer to increase the growth of tomato and soil microbial activities. The use of organic matter on tomato cultivation is focused toTdecrase thr utilization of chemical subtances for minimizing environmental degradation. An experiment was conducted in Cidawu village, Cibodas, Cianjur (1,250 m asl) to determine the suitable and effective inoculant to increase the growth of tomato plants, and also to stimulate soil microbial activities. The tomato variety used was Gondol. . The organic fertilizers were compost, chicken-dung plus rise husk, and Phosphate Solubilizing Bacteria (PSB), as biofertilizer. The aim of the experiment was to find the suitable and effective inoculant on the tomato and its expected to increase the growth of the plant. A Randomized Block Design with three replications was utilized in experiment. The treatmens consisted of without organic fertilizers or PSB (control)(K), inoculation of PSB (P1), application of compost (P2), application of chicken dung plus rise husk (P3), application of chemical fertilizer (NPK)(P4). The result showed that the application organic fertilizer and PSB increased the growth of tomato plant and also PSB population, acid and alkaline phosphatase activities in the soil after harvesting. The inoculation of PSB resulted in heighest plant height (108.3 cm) compared to control (72.3 cm) and also the highest tomato yield compare to the control treatment (88.2 persen ), and even it was higher than the yield caused by the application of the chemical fertilizer. The highest increase of PSB population and the activities of acid and alkaline phosphatase enzymes in soil after harvesting of the PSB inoculant compared to the other tratments. The application of organic fertilizer and PSB for wide scale cultivation of tomato expectantly play an important role for increasing production, productivity, and quality of tomato to fulfill market demand for the product.
