Pertumbuhan, Kandungan Klorofil dan Serat Kasar pada Defoliasi Pertama Alfalfa (Medicago sativa L ) Akibat Pemupukan Mikorisa

摘要: Research about growth, chlorophyl and fibre content at first defoliation in alfalfa (Medicago sativa L)after giving biofertilizer mycorrhiza have been done.. This research beginning 15 March 2006 – 15agustus on biological garden FPMIPA UNNES Semarang, using plastic polybag, anddesign of complete randomized design, one treatment that is give mycorriza with fiveconcentration Mo ( without mikorizzsa); M1 ½ capcule/plant ;  M2 1 capcule/plant), M3 ofmikorizza 11/2 capcule/plant) M4 2 capcule/plant). Every repeating 5 times. Chlorophyllcontent determined to use method Arnon 1949 Hukmani & Tripathy, 1994); Fibre used bymethod AOC 1970 Sudarmaji, 1984 data analyzed this by computer SPSS-13 program.Result show there are high difference plant , sum dry weight firstdefoliation.
