Abstract

ABSTRAKPenelitian bertujuan untuk memperoleh spesies-spesies gulma potensial sebagai sumber pakan ternak, berdasarkan pada produksi, dominansi, dan nilai nutrisi. Penelitian dilaksanakan di lahan sawah KecamatanSungai Serut, Kota Bengkulu. Dibuat petak sampel berukuran 1 m x 1 m sebanyak lima puluh petak sampel dengan metode jalur transek. Gulma dipanen dengan akarnya, kemudian dicuci, dipilah-pilahkan menurutjenisnya, dihitung jumlah jenis dan jumlah individu untuk setiap jenis, dihitung ditimbang, dianalisis kandungan nutrisinya (bahan kering, Protein kasar, kalsium, posfor) dan kandungan energi. Berdasarkanpenelitian ditemukan 23 spesies gulma, dan lima jenis dominan adalah Gulma X (Ordo Poales), Fymbristilis milliaceae, Lindernia anagalis, Cyperus halpan, Ludwigia perennis, dengan nilai SDR berturut-turut adalah 18,30 %; 11,92 %; 10,82 %; 8,94 %; 7,55%; produksi biomasa 495,96 kg/ha atau 27,87 %; 206,2 kg/ha atau 11,15 %, 127.9kg/ha atau 7,19 % , 94.08 kg/ha atau 5,29 %. Kandungan protein 5,28 %; 6,89 %; 5,97%; 6,01 %; 7,39. Kandungan kalsium : 0,02 %; 0,09 %; 0,13 %; 0,08 %; 0,06 %; kandungan posfor 0,16 %; 0,33%; 0.57%; 0,26 %; 0,296 %. Seluruh gulma dominan menyebar secara berkelompok. Dapat disimpulkan bahwa gulma dominan mempunyai potensi sebagai sumber pakan.Kata kunci : spesies, gulma sawah, dominansi, produksi, nutrisi

Abstract

[EFFECTS OF PALM OIL SLUDGE SUBTITUTION FOR SYNTHETIC N FERTILIZER ON GROWTH AND YIELD OF SWEET CORN]. Palm oil sludge (POS) contains high concentrations of organic nitrogen dan its can serve as an alternative for synthetic nitrogen fertilizer. Objective of this study was to compare the growth and yield of sweet corn as amended with different compositions of synthetic N fertilizer and palm oil sludge. Six compositions, each containing 138 kg N/ha were assigned as the treatment and arranged in a randomized complete block design with three replications. These were 100% synthetic fertilizer, 80% synthetic fertilizer + 20% POS, 60% synthetic fertilizer + 40% POS, 40% synthetic fertilizer + 60% POS, 20% synthetic fertilizer + 80% POS, and 100% POS. The results of this study indicated that the plot amended with 60% synthetic fertilizer + 40% POS produced the highest plant stature (176.4 cm), stem diameter (2.40 cm), leaf area (8712.82 cm2 ), plant fresh weight (375.19 g), plant dry weight (136.68 g), and husked ear length (17.93 cm). However, the highest observed husked ear yield was only about 61.6 % the yield potential of the sweet corn variety.

Abstract

Planting wetland paddy by setting row space could be a method to increase rice production. Legowo system is row planting method where we are able to apply different row types on paddy field. The objective ofthis research was to identify the best row planting type of ?Jajar Legowo? on growth and yield of wetland paddy. Six row plantings, including 2:1 type (means 2 rows are splited by wide space/ legowo), 3:1 type, 4:1 type, 5:1type, 6:1 type, and 7:1 typ, were tested in a Randomized Complete Block Design with 3 replications Results of the experiment revealed that the highest growth and yield as showed by total number of tillers (28), number ofproductive tillers (25), dry-mill rice (66.16 g per plant), and yield difference of dry-mill rice (50.43% per plot) was found at row planting type 2:1. Therefore, row planting type 2:1 can be selected as the best row.

Abstract

Ultisol is one of marginal land type quite extensively presence in Indonesia, including the province of Bengkulu. The use of varieties tolerance to acidity stress is the best manner to utilize of this type of land with relatively low cost and environmentally friendly. The objective of this research was to evaluate theyield potential of six maize hybrids developed to soil acidity tolerance. The experiment was conducted at the Experimental Farm Medan Baru, Kandang Limun Village, Muara Bangkahulu District, Bengkulu City, from August to November 2015. The experiment was arranged in a randomized completely block design with four replications. As the treatment were newly developed maize hybrids, namely CT5, CT8, CT9, CT13, CT14 and CT15. The variables measured were cob length, cob diameter, 100-seed weight and the estimated yield/ha. Qualitative variables supporting to corn yield were the cob position, seed color, seed type and seed row arrangement. The results indicated that the hybrid CT8 showed the highest estimated yield in Ultisol among hybrids evaluated, with the estimation of 6.5 tons per hectare. Qualitatively, theseeds of hybrid CT8 were a horse tooth type, pale yellow color, and stright line arrangement.
