PERANAN LIMBAH PERTANIAN DAN TINGKAT PEMUPUKAN NPK TERHADAP PERTUMBUHAN DAN HASIL BAWANG MERAH (Allium ascalonicum L.) DI LAHAN PASANG SURUT TIPE LUAPAN D.

Increasing national food production needs to be done by applying production technology through the use of organic fertilizers. Soil fertility can be restored by adding fertilizer. The use of various types of agricultural waste can be used to make organic fertilizer, namely rice straw, banana weevil, water hyacinth, coconut fiber. This organic fertilizer is applied to the soil in solid form on shallot plants grown on tidal soil type D overflow, in Sukajadi village, kec. . Talang Kelapa Banyuasin Regency. The purpose of the study was to obtain a dose of agricultural waste organic fertilizer that could reduce the use of inorganic NPK fertilizers in tidal land, and it was hoped that it would be very useful for users as an applicative technology that was economically profitable and technologically easy to apply, for the government to overcome the problem of fertilizer scarcity and for the community. especially farmers can increase their production and standard of living. The split plot design used in this research was designed with 9 treatment combinations with 3 replications, 27 plots and 5 sample plants were obtained. The treatment factors are as follows: 1. Main Plot : fertilization rate of Compound NPK Fertilizer (N) N1 = 25% of Recommended Dose, N2 = 50% of Recommended Dose, N3 = 75% of Recommended Dose, 2. Sub-plots : Fertilizer Dose Agricultural waste (L) L1 = 5 tons/ha, L2= 0 tons/ha, L3 = 15 tons/ha. The data obtained were tested statistically using SPSS 26 software program. The variables observed in this research were plant height (cm), tuber weight per plot and tuber weight per clump. The results showed that the application of organic fertilizer from agricultural waste 15 tons/ha with 75% NPK fertilizer resulted in the best growth and yield of shallots at 11.30 tons/ha.
