Abstract

The general objective of the research is to obtain sustainable land recovery technology as aresult of intensive use of artificial chemical fertilizers. The specific purpose of this research is: a). a). Get the optimal dose of biophosphate fertilizer for the growth and yield of several varieties of peanuts, b). Get peanut varieties that have high productivity, c). Look at the interaction between bio-phosphate doses and peanut varieties. The study was conducted at the Lampung State Polytechnic Practice Garden from July to December 2017. The study was a factorial experiment in a randomized block design consisting of 2 factors. As the first factor is the dose of biophosphate fertilizer, namely: P0 = 0 kg/ha, P1 = 50 kg/ha, P2 = 100 kg/ha and P3 = 150 kg/ha. While the second factor is peanut varieties, namely: V1 = Gajah, V2 = Kelinci, and V3 = Takar, so that 12 treatment combinations are obtained. If there is a difference in the middle value, it is followed by a test of honest difference (BNJ) at the level of 5%. Based on the results of the study some conclusions can be drawn; (a) The provision of bio-phosphate treatment at a dose of 50 kg / ha gives the highest plant height compared to other treatments, while the Takar variety has a higher plant height compared to Gajah and Kelinci. (b) The provision of bio-phosphate treatment of 150 kg / ha gave the lowest yield of pods compared to 100 kg / ha and 0 kg / ha of bio-phosphate, while the Takar variety gave a better number of filled pods compared to Gajah and Kelinci. (c) The content of pods per plant gives the same results as the number of filled pods. Keywords : bio-phosphate, peanut, organic.
