Abstract

Tujuan penelitian adalah untuk mengkaji pemupukan arang aktif urea pada rumput gajah terhadap kecernaan bahan kering (KcBK), kecernaan bahan organik (KcBO) dan produksi VFA. Penelitian menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 ulangan yaitu T1=0% (tanpa arang aktif) dengan urea 1,0 g/tanaman , T2=5 g arang aktif dengan urea 1,0 g/tanaman, T3=10 g arang aktif dengan urea 1,0 g/tanaman dan T4=15 g arang aktif dengan urea 1,0 g/tanaman. Parameter  yang diamati : Kecernaan bahan kering, kecernaan bahan organik, produksi VFA, Produksi NH3. Hasil penelitian menunjukkan bahwa terdapat pengaruh yang nyata (P<0,05) pemupukan arang aktif urea terhadap kecernaan bahan kering, kecernaan bahan organik, produksi VFA dan produksi NH3. Simpulan penelitian yang diperoleh menunjukkan bahwa pemupukan arang aktif urea pada T3 dan T4 menghasilkan kecernaan (bahan kering dan bahan organik) serta fermentabilitas (produksi VFA dan NH3) nutrien rumput gajah secara in vitro yang tertinggi.

Abstract

The high concentration of sodium chloride (NaCl) in saline soils has negative effects on the growth ofmost plants. The experiment was designed to evaluate macro nutrient uptake (Nitrogen, Phosphorus andPotassium) of forage grasses at different NaCl concentrations in growth media. The experiment wasconducted in a greenhouse at Forage Crops Laboratory of Animal Agriculture Faculty, Diponegoro University.Split plot design was used to arrange the experiment. The main plot was forage grasses (Elephant grass(Pennisetum purpureum ) and King grass (Pennisetum hybrida)). The sub plot was NaCl concentrationin growth media (0, 150, and 300 mM). The nitrogen (N), phosphorus (P) and potassium (K) uptake in shootand root of plant were measured. The result indicated increasing NaCl concentration in growth mediasignificantly decreased the N, P and K uptake in root and shoot of the elephant grass and king grass. Thepercentage reduction percentage of N, P and K uptake at 150 mM and 300 mM were high in elephant grassand king grass. It can be concluded that based on nitrogen, phosphorus and potassium uptake, elephantgrass and king grass are not tolerant to strong and very strong saline soil.

Abstract

The research was conducted to evaluate the effect of mulch and mixed cropping grass – legume atsaline soil on growth, forage yield and nutritional quality of guinea grass. Saline soil used in thisresearch was classified into strongly saline soil with low soil fertility. The research was arrranged inrandomized complete block design with 3 blocks. The treatments were : M1 = guinea grassmonoculture, without mulch; M2 = guinea grass monoculture, 3 ton/ha mulch; M3 = guinea grassmonoculture, 6 ton/ha mulch, M4 = mixed cropping grass with Sesbania grandiflora, without mulch;M5 = mixed cropping grass with Sesbania grandiflora, 3 ton/ha mulch; M6 = mixed cropping grass withSesbania grandiflora, 6 ton/ha mulch. Data were analyzed using analysis of variance, then followed byDuncan's Multiple Range Test. The highest soil moisture content was achieved at mixed cropping grasslegumewith 6 ton/ha of mulch. The effect of mulch at saline soil significantly increased plant growth,forage yield and nutritional quality of guinea grass. Application of 3 ton/ha mulch increased plantgrowth, forage yield and nutritional quality of guinea grass. Plant growth, forage yield and nutritionalquality of guinea grass were not affected by monoculture or mixed cropping with Sesbania at saline soil.

Abstract

The objective of this study was to evaluate the effect of manure at saline soil on forage production, quality and livestock carrying capacity of P. maximum and S. grandiflora. The research was conducted on moderately saline soil at Rembang Regency, Central Java Province, Indonesia.Randomized complete block design was used as design experiment. The treatments were different dosage of manure as organic amendment (0, 10 and 20 tonnes/ha). Forage crops were P. maximum and S. grandiflora that planted monoculture or mixed-cropping. Parameters measured were dry matter (DM) production, ash, crude protein, crude fibre, ether extract, total digestible nutrients. P. maximum was cut eight times, S. grandiflora was cut six times during one year. The result showed that the highest total dry matter production of mixed cropping P. maximum and S. grandiflora was available at moderately saline soil with application 20 ton/ha manure. Total production of dry matter, crude protein and total digestible nutrient available at application 20 ton/ha manure were 29131 kg/ha/year; 3722 kg/ha/year and 17718 kg/ha/year, respectively. Carrying capacity based on dry matter, crude protein and total digestible nutrients were 10.8 AU/ha/year; 13.6 AU/ha/year and 11.3 AU/ha/year, respectively. In conclusion, application of 20 ton/ha manure at saline soil increased production, crude protein and carrying capacity.
