Forage production in saline soil treated with organic fertilizer used as feed for growing goats

摘要

The research was conducted (i) to evaluate the effect of application of organic fertilizer in saline soil on forage production of Panicum maximum and Sesbania grandiflora; and (ii) to evaluate the use  of Panicum maximum and Sesbania grandiflora foliage for growing goats. The study was conducted during the dry season (June – October 2016) in saline soil (EC = 4.1 dS/m) in Kaliori sub-district area, Rembang Regency, Central Java Province, Indonesia. Experiment 1 was to measure production of P. maximum and S. grandiflora at different dosages of organic fertilizer ( 0, 10 tonnes/ha and 20 tonnes/ha) planted solely or inter-planted. Experiment 2 was the use of the forages for growing goats: native grass and Leucaena leucocephala (80 % : 20%) and P. maximum and S. grandiflora (80% : 20% and 60% : 40%). Organic fertilizer (cow dung) application on saline soil increased dry matter production of P. maximum and S. grandiflora planted solely or inter-planted. There were increases in DM intake of 60%, in live weight gain of 100%, and improvements in DM feed conversion of 23%, for combinations of  P. maximum : S. grandiflora (80 : 20) and (60 : 40) compared with Native grass : L. leucocephala (80 : 20).
