Aplikasi Beberapa Dosis Kompos Tkks Yang Diperkaya Trichodherma Harzianum Rifai Dan Pupuk Npk Pada Budidaya Bawang Merah
ABSTRACT
Shallot (Allium ascalonicum L.) is a horticultural commodity that is widely consumed by the Indonesian people as a mixture of spices and medicines. Onion production in Riau fluctuates from year to year so it is necessary to develop cultivation techniques by combining the use of organic fertilizers with inorganic fertilizers. The source of organic fertilizer material can be composted empty palm bunches (TKKS) enriched with Trichoderma harzianum Rifai. Inorganic fertilizers that are often used in agricultural cultivation are NPK fertilizers. This study aims to examine the effect of a combination of application of several doses of TKKS compost enriched with T. harzianum Rifai and NPK fertilizer, as well as to obtain a combination of TKKS compost and NPK doses that are better able to increase shallot growth and production. This research is an experimental study using a factorial complete randomized design (CRD) with 2 factors and obtained 8 treatment combinations with 3 replications, resulting in 24 experimental units. Each experimental unit consisted of 3 polybags, so this study consisted of 72 polybags. The treatments in this study were K0 = TKKS 0 g/polybag, K1 = TKKS 50 g/polybag, K2 = TKKS 100 g/polybag, K3 = TKKS 150 g/polybag. P1 = 100% NPK 2.5 g/polybag, P2 = 50% NPK 1.25 g/polybag. The results obtained were analyzed statistically and variance analysis using the SAS version 9.1 application. Results that had a significant effect were further tested with the DNMRT test at the 5% level. The combination of TKKS compost enriched with T. harzianum Rifai at a dose of 30 t.ha-1 and NPK fertilizer 250 kg.ha-1 can increase the number of tubers, wet and dry weight of tubers.
