This study aimed to determine the effect of arbuscular mycorrhizal fungi (AMF) and phosphate (P) fertilizer on the nutrient content, phosphate uptake and in vitro digestibility of alfalfa (Medicago sativa L.).The research was conducted at green house of Forage and Pastures Science Laboratory, Faculty of Animal Science Universitas Gadjah Mada. The experiment was arranged in Completely Randomized Design using 3x4 factorial patterns with four replications. The first factor was dosage of phosphate fertilizer SP 36 (0, 60, and 120 kg/ha). Second factor was the dosage of AMF (0, 0.8, 1.6, and 2.4kg/ha). The variable measured was nutrient contents (crude protein, dry matter, and organic matter), total P uptake and dry matter and organic matter in vitro digestibility. The results showed that the interaction of AMF and P fertilizer had no significant effect on crude protein and total P uptake, but highly significant effect on the parameters of dry matter, organic matter and dry matter and organic matter in vitro digestibility.

Azolla pinnata contains a high nutritional value with a high protein content of 25%, so it can be used as an alternative to animal feed. The low production of Azolla is caused by the suboptimal use of fertilizers. This study aims were to determine the type of manure (composted manure from poultry, goats, and rabbit) which was the most optimal in producing Azolla. Azolla pinnata was planted at 5050×10 cm (W×L×H) soil pools coated with plastic sheets. To maintain the acidity of the media, 10% (2 kg) of sludge fields was added to each pond. Water and animal waste compost (5 g/L) were added to each pond as a treatment. The treatments were: paddy mud (K0), paddy mud + poultry composts (K1), paddy mud + compost rabbit manure (K2) and paddy mud + compost goat manure (K3). Each treatment was repeated 5 times. Measurements made were pH of the media, area of cover, yield (g weight of dry matter) and crude protein content of Azolla. Harvesting was done every 14 days. The results showed that the Azolla dry matter production of K1, K2 and K3 treatments were greater (p<0.01) than K0 (20.80, 18.20, and 19.00 vs. 10.40 g/2,500 cm 2 ; respectively). Among the compost treatments, the crude protein content of K1 and K2 were higher than K0 and K3 (25.34 and 26.25 vs. 13.11 and 22.96%, respectively; p<0.01). Fertilizing with rabbit or poultry compost was the best in improving Azolla production and crude protein content.

The aimed of the research conducted to determine the effect of composition on the quality of forage pellet. This study used fresh Legetan (Synedrella nodiflora) for major material of forage pellets, while rice bran was additional feed ingredients. There was two (2) variation of forage pellet consisting of A (80% Legetan + 20% rice bran) and B (90% Legetan + 10% rice bran). These materials were formulated based on dry matter (DM). The mixture of ingredient were conducted in the form asfed, and then pelletized and dried (under sunlight
