Peningkatan Produktivitas Padang Penggembalaan Kritis melalui Pertanaman Campuran antara Rumput dan Legum sebagai sumber Biological Nitrogen Fixation(BNF) di Kabupaten Sidenreng Rappang, Sulawesi Selatan

Abstract

-This study aimed to verify the effect of the use of BNF (Biological Nitrogen Fixation) on the productivity of pasture through a combination of grasses and legumes. This study was designed using a completelyrandomized design with pattern factorial (4x3x3) which consists of 4 types of grasses and legumes, 3 replications and 3-level portion of grasses and legumes, namely: (a) K1P0 (80%Eleusine indica + 20%Centrocema pubescens), K1P1 (80% Brachiaria decumbens+ 20%Stylosanthes humilis), K1P2 (80% Pennisetum purpureum cv mott + 20% Pueraria javanica), K1P3 (80% Panicum Maximum + 20% Macroptillum atropurpureum); (b) K2P0 (70% Eleusine indica+ 30%Centrocema pubescens), K2P1 (70% Brachiaria decumbens + 30%Stylosanthes humilis), K2P2 (70% Pennisetum purpureum cv mott + 30% Pueraria javanica), K2P3 (70% Panicum Maximum + 30% Macroptillum atropurpureum); (c) K3P0 (60% Eleusine indica + 40%Centrocema pubescens), K3P1 (60% Brachiaria decumbens + 40%Stylosanthes humilis), K3P2 (60% Pennisetum purpureum cv mott + 40% Pueraria javanica), K3P3 (60% Panicum Maximum + 40% Macroptillum atropurpureum). The results showed that all of the treatment combination of grasses and legumes (BNF) from the components of growth, nitrogen fixation abilityand dry matter production capability as well as fresh give very real influence. However, among the combinations of grasses and legumes are best obtained successively at K3P2 (60% Pennisetum purpureumcv mott+ 40% Pueraria javanica); followed K3P3 (60% Panicum Maximum + 40% Macroptillum atropurpureum); and K3P0 (60% Eleusine indica + 40%Centrocema pubescens)
