Nutrient content of Alfalfa (Medicago sativa L.) regrowth i in different fertilizers and lighting

This research was conducted to study the effect of fertilizer types and photoperiod on the nutrient content of regrowth I on alfalfa (Medicago sativa L.). The variables measured were nutrient content i.e dry matter (DM), organic matter (OM), crude protein (CP), and crude fat (CF). The research applied statistical analysis Completely Randomized Design (CRD) factorial pattern 5x3 and t-test. If it resulted in a significant effect, it was continued with Duncan's multiple range test (DMRT). The first factor was types of fertilizer consisted of P0=control, P1=green fertilizer and dolomite, P2=manure, green fertilizer and dolomite, P3=dolomite, and P4=green fertilizer® and dolomite. The second factor was the photoperiod consisted of C0=12 h, C1=16 h, and C3=20 h. The results showed that the fertilizer types treatments were significantly affected (P<0,05) regrowth I DM, and regrowth I CF. While photoperiod treatment were significantly affected (P<0,05) regrowth I DM, regrowth I OM, and regrowth I CF. The interaction between the types of fertilizer and photoperiod treatment was significantly affected (P<0,05) regrowth I DM and CF. Based on research results, it can be concluded that the types of green fertilizer from PIAT and dolomite to produce the nutrient content regrowth I was the highest, resulting in 22,18 DM, 29,32 CP, 9,38 CF respectively. The nutrient content of regrowth I that produce the highest results of photoperiod was 12 h = 28,80 CP, 16 h = 20,92 DM, 20 h = 89,38 OM, 9,16 CF.
