Title: APPLICATIONS OF BIOFERTILIZER, AMELIORANT, NPK FERTILIZER ON NTOTAL, AVAILABLE P, GROWTH AND YIELD OF CORN PLANT IN INCEPTISOLS |
Abstract: Biofertilizer is a single or consortia of microorganisms added into carrier and applied as a means
to improve crop yield. This experiment aimeds to the interaction between N and P biofertilizer,
ameliorant, compound NPK fertilizer application towards soil total-N, Available-P, and Bisi-2
corn yield grown on Pasir Banteng Inceptisols. This experiment was conducted in the
experimental field in Pasir Banteng, Tanjungsari, Sumedang District, Randomized Block Design
(RDB) experimental design consisted of various biofertilizer with ameliorant, combinations with
4 levels. The first factors were : a0: (control), a1:1.2 kg ha-1 N biofertilizer + 1.2 kg ha-1 P
biofertilizer, a2:2000 kg ha-1 of ameliorant, a3:1.2 kg ha-1 N biofertilizer + 1.2 kg ha-1 P
biofertilizer + 2000 kg ha-1 of ameliorant. The second factor was NPK dose with four levels
(f1:100%, f2:80%, f3:60%, f4:40%). The total combination were 16 treatments combination and
each combination was repeated three times. The results showed biofertilizer, ameliorant, with
NPK fertilizer were increase plant height, N-Total soilcontent, cob weight without husk, and
corn kernel weight per plant. The use of biofertilizers and ameliorant on corn grown in Pasir
Banteng Inceptisols not been able to reduce the dose of NPK fertilizer is used. |
