Kombinasi Dosis Pupuk N, P, K Dengan Frekuensi Pupuk Hayati Untuk Pertumbuhan Dan Hasil Tanaman Kacang Hijau (Vigna Radiata L.)
ABSTRACT
Mungbean plants are one of the most important food crops for the community after soybeans. Generally, farmers use inorganic fertilizers continuously which can have an impact on reducing soil fertility. Efforts can be made to increase the production of mungbean plants, one of which is by applying Bacillus cereus biofertilizer. This research was conducted experimentally using a completely randomized design (CRD) with 5 treatment levels. The treatment levels were repeated four times to obtain 20 experimental units. The treatment consisted of 5 levels, namely N, P, K 100% + without applying biofertilizers; fertilizer N, P, K 75% + 3 times the application of biofertilizers; fertilizer N, P, K 75% + 4 times the application of biofertilizers; 50% N, P, K fertilizer + 3 times application of biofertilizers and 50% N, P, K fertilizer + 4 times application of biofertilizers. Parameters observed were plant height, percentage of effective root nodules, flowering age, harvesting age, number of productive branches, number of seeds per plant, percentage of fruitful pods per plant, the weight of 100 seeds, dry seed weight per plant, and harvest index. The results showed that the combination of 75% N, P, K fertilizer and 4 times the frequency of biofertilizers (10 ml per plant) only affects the harvesting age of mungbean plants.
