EVALUATION PERFORMANCE OF THREE Pennisetum GENUS GROWN ON PINES FOREST IN LEMBANG, WEST JAVA

Abstract

Pines are the largest tree forests in West of Java so that they are very potential to be developed as an agroforestry system. Forage crop potentially to be cultivated in the agroforestry system. The aim of the research was to study the response of the grasses grown under pines forest. The experiment was conducted at pines forest area arranged in randomized complete block design. The treatments were 3 grasses (Pennisetum purpureum cv. Taiwan, P. purpureum (local) and Pennisetum purpureophoides (king grass). Data collected were productivity, agronomic performance (plant height, tiller), forage production and quality. The result shows that shoot production of Taiwan cultivar was significantly higher than local P. purpureum. It was produced 498.4 g/clump on rainy season and 287.0 g/clump at dry season. At dry season forage production was decreased by 39,9%/ha. Nutrient composition at rainy season, crude fibre of grass was 39.89%; Ca 0.04%; P 0.26%; ash 12.46%; energy 4239.5 kcal/kg and crude protein 8.23%; while at the mid of dry season crude fibre was 38.43%; Ca 0.035%; P 0.26%; ash 11,43%; energy 3943 kcal/kg and crude protein 8.94%. EVALUASI PERFORMAN TIGA JENIS RUMPUT Pennisetum sp DI BAWAH TEGAKAN TANAMAN PINUS DI LEMBANG JAWA BARAT ABSTRAKTanaman pinus di Jawa Barat cukup besar dan sangat potensial untuk pengembangan sistem agroforestry. Tanaman pakan ternak untuk dibudidayakan pada sistem agroforestry sangat potensial. Penelitian ini untuk mempelajari respon rumput gajah di bawah tanaman pinus. Rancangan percobaan acak kelompok dengan perlakuan rumput gajah lokal (Pennisetum purpureum local), rumput raja (P. purpureophoides) dan rumput gajah Taiwan (P. purpureum cv Taiwan) dengan lima ulangan masing-masing ditanam dengan ukuran plot 100 m2. Interval potong delapan minggu dan pengumpulan data meliputi produksi dan kualitas hijauan, performan agronomi (tinggi tanaman, jumlah tunas). Hasil penelitian menunjukkan bahwa produksi tunas rumput gajah Taiwan nyata lebih tinggi daripada rumput gajah lokal. Produksi hijauan per rumpun 498,4 g pada musim hujan dan 287,0 g pada musim kering. Produksi hijauan pada musim kering menurun 39,9%/ha. Kandungan nutrisi pada musim hujan serat kasar adalah 39,89%, Ca 0,04%; P 0,26%, Abu 12,46%; energi 4239,5 kcal/kg dan protein kasar 8,23%. Sedangkan pada pertengahan musim kering serat kasar 38,43%; Ca 0,035%; P 0,26%; abu 11,43%; energy 3943 kcal/kg dan protein kasar 8,94%.Kata kunci: hutan pinus, tanaman pakan ternak, produksi, kualitas

The Effect of Harvest Age on Different Regrowth on Chicory (Cichorium intybus L.) Forage Yield by Intercropped with Pennisetum purpureum cv. Mott

“…This was because dwarf elephant grass had more tillers so that the harvest is at the second regrowth the tillers' growing abilities were greater in comparison to the first regrowth. Sajimin and Purwantari (2019) stated the number of tillers in the dry season Pennisetum purpureum cv. Taiwan as much as 13.8, Pennisetum purpureophoides as much as 9.6 meanwhile Pennisetum cv.…”

Supplementation of Prill Fat Derived from Palm Oil on Nutrient Digestibility and Dairy Cow Performance

“…Dairy cows in Indonesia mostly fed with Napier grass and concentrate which produced by cooperative (Zahera and Permana, 2015). Napier grass is a productive forage (250 ton/ha/year) (Despal et al, 2019) but it has a low quality (55% Total Digestible Nutrient(TDN), 8-12% Crude Protein (CP)) (Riestanti et al, 2020) and is influenced by seasons (Sajimin and Purwantari, 2019). To fulfil the requirement of dairy cattle average production (13.5 L/head/day) that require 60.9% TDN and 12.20% CP (NRC, 2001), dairy farmers often added concentrate.…”
