Abstract

Utilization of forages grown underneath the plantation crops is widely practices in the region of Southeast Asia and in the Pacific island. Since the plantation crops do not fully utilize all incoming radiation and nutrients, their competition with natural vegetation for nutrients is inevitable. In coconut plantation native forages and natural vegetation cannot survive under heavy grazing due to lack of grazing management practiced by farmers. This will lead to overgrazing and compacting the soil and in some circumstances triggering erosion, changing in botanical composition due to invasive weeds, and disappearance of the planting forages species. This disappearance is also probably due to other factors such as intolerance of those species in the shaded environment. However, this is not the case. Although shade tolerance species are planted, the pasture run-down still occurs. To overcome this problem there are three new approaches. The first one is that defoliation should based on biogeochemical process consideration.  It is should pay attention on the rhizosphere environment to ensure the nutrients uptake by forage, especially grasses is fulfilled.  The second one is that defoliation should ensure the health of the grass subject to cutting. With the climate change phenomenon, where the air CO2 is abundance, following by the increasing of air temperature, the time of defoliation or grazing should be focused on counting the accumulation of heat unit rather than focusing on forage’s age. The third one is that the appropriate grazing systems and stocking rate should take into account, to ensure the plant to have ability to recover after grazing.

Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian pupuk NPK terhadap Potensi Produksi Rumput Brachiaria .humidicola cv. Tully dan Penisetum purpureum cv. Mott. Metode yang digunakan pada penelitian ini adalah model experimental dengan menggunakan Rancangan Acak kelompok (RAK) dengan pola Faktorial. Faktor A jenis rumput : a1 = Rumput B. humidicola cv. Trully ; a2 = Rumput P. purpureum cv. Mott. Faktor B jenis pupuk b1 = Pupuk tunggal N (Urea) ; b2 = Pupuk kombinasi NP (Urea + TSP) ; b3 = pupuk kombinasi NPK (Urea + TSP + KCl). Dosis pupuk yang digunakan Urea= 150 kg/ha, TSP = 75 kg/ha, KCl = 75 kg/ha, sehingga terdapat 6 kombinasi perlakuan dan masing-masing perlakuan diulang sebanyak 4 kali. Jumlah keseluruhan satuan percobaan adalah 24 satuan percobaan. Penelitian ini dilaksanakan di Kebun Percobaan, yang terletak di desa Talawaan Bantik Kecamatan Wori Kabupaten Minahasa Utara Provinsi Sulawesi Utara. Hasil analisis menunjukkan bahwa jenis rumput, jenis pupuk dan interaksi jenis rumput dan jenis pupuk memberikan hasil yang berbeda sangat nyata (P<0.01) terhadap potensi produksi segar, potensi produksi bahan kering dan potensi produksi protein. Potensi produksi segar, potensi bahan kering, dan potensi produksi protein rumput B sangat nyata (P<0,01) lebih tinggi dari rumput A. Potensi produksi segar, produksi bahan kering, produksi protein rumput yang diberikan pupuk NPK sangat nyata lebih tinggi (P<0.01) dari rumput yang diberikan pupuk NP dan N secara tunggal.Pemberian pupuk NPK menghasilkan potensi produksi segar, potensi produksi bahan kering dan potensi produksi protein masing-masing 53,15%, 40,48%, dan 77,26% lebih tinggi dibandingkan pemberian pupuk N secara tunggal. Rumput B yang diberikan pupuk NPK menghasilkan potensi produksi segar, potensi produksi bahan kering dan potensi produksi protein yang paling tinggi.

Abstract

ABSTRACT   The purpose of this study was to calculate the productivity of corn straw, and to measure the quality of corn straw as cattle feed at different altitude conditions, at South Minahasa regency. The research was conducted in May through September 2011, starting from collection of secondary data, primary data, on-site observations, corn straw sampling, and shipment of samples to be analyzed in Ruminant Animal Nutrition Laboratory and Livestock Chemistry, Faculty of Animal Science University of Padjadjaran Bandung. The results of the t-test analysis showed that there was a very significant difference  between the protein, Neutral Detergent Fiber, Acid Detergent Fiber, and the production of corn straw in the lowlands and the highlands. Where in highlands, the production of corn straw and hay protein content was higher than in the lowlands, in lowland area was a reverse. A component of the Acid Detergent Fiber (ADF) and Neutral Detergent Fiber (NDF) was lower in the highlands than in lowlands. Corn straw can also be utilized as an animal feed based on Total Digestible Nutrient (TDN). Total Digestible Nutrient in West Amurang district was 2,204,785 kg (2,204.8 tons), while in Kumelembuai district, its was found only 877,533 kg (877.5 tons). It is concluded in this research that there were differences in the production of corn straw, protein, ADF, and NDF between lowland and upland areas. The protein content and the corn straw production as well as the content of ADF and NDF were higher in highland areas. Keywords : Corn straw, NDF, ADF   ABSTRAK   Tujuan penelitian untuk menghitung produktivitas jerami jagung dan tuntuk mengukur kualitas jerami jagung sebagai pakan ternak sapi pada kondisi ketinggian berbeda di Kabupaten Minahasa Selatan. Penelitian berlangsung sejak bulan Mei sampai dengan September 2011, mulai dari pengambilan data sekunder, data primer, pengamatan di lokasi, pengambilan sampel jerami jagung dan pengiriman sampel untuk dianalisis di Laboratorium Nutrisi Ternak Ruminansia dan Kimia Makanan Ternak Fakultas Peternakan Universitas Padjajaran Bandung. Hasil analisis uji t menunjukkan bahwa terdapat perbedaan yang sangat nyata protein, Neutral Detergent Fiber (NDF), Acid Detergent Fiber (ADF), dan produksi jerami jagung di dataran rendah dan dataran tinggi, di mana di daerah dataran tinggi produksi jerami jagung dan kandungan proteinnya lebih tinggi daripada di dataran rendah, tetapi untuk komponen ADF dan NDF lebih rendah di dataran tinggi daripada di daerah dataran rendah. Jerami jagung juga dapat memberikan kontribusi sebagai pakan ternak dilihat dari Total Digestible Nutrien (TDN) untuk Kecamatan Amurang Barat sebesar 2.204.785 kg (2,204.8 ton) TDN, sedangkan di Kecamatan Kumelembuai adalah sebesar 877.533 kg (877,5 ton) TDN. Hasil penelitian disimpulkan bahwa ada perbedaan produksi jerami jagung, kandungan protein, ADF, dan NDF antara daerah dataran rendah dan daerah dataran tinggi. Kandungan protein dan produksi jerami jagung lebih baik di dataran tinggi, sedangkan dilihat dari kandungan ADF dan NDF masih lebih baik di dataran rendah.

Abstract

RESPONS OF FORAGES COVER CROPS ON LEVEL OF ORGANIC FERTILIZER BOKASHI AND PLANT POPULATION DENSITY. The objectives of this research was to asses the interaction of bokashi levels and plant population density on vegetative growth of sorghum Brown Midrib (BMR) and Leucaena leucocephala legume trees. Level bokashi were LB1 = 0 G; LB2 = 200 G; LB3 = 400 G and LB4 = 800 G pot-1 interact with plant population density of KP1 = 2 plants; KP2 = 4 plants and KPB3 = 6 plants pot-1 of BMR, and for Lamtoro plant density were KP1= 1 plat, KP2= 2 plant, KP3= 3 plant and KP4 = 4 plant pot-1. Treatments were arranged in a 4 x 3 factorial with 3 replications based on a Completely Randomized Design. Variable measured were leaf length of leaf, number of leafes and plant height. The results showed that the interaction of both treatment had significant effect on leaf length (P<0.05), but did not have significant effect (P>0,05) on number of leafs and plant height of BMR. On the otherhand the optimum plant density was 3 plant per pot. Based on this results can be concluded that to get optimal vegetative growth of sorghum BMR needs bokashi fertilizer by 400 G/polybag at density of 2 plants/polybag, but up to 3 plant per pot for lamtoro.Keywords:Bokashi level of chicken manure, plant population density level, growth sorghum, growth.
