“…Akar yang terbentuk dari ruas stolon mengikat tanah dengan rapat sehingga tahan terhadap injakan ternak bahkan di bawah penggembalaan yang berat. Produksi segar rumput S. secundatum di perkebunan sawit pada Tabel tersebut diatas sebanyak 2,16 kg/m2 dengan kandungan bahan kering 28,62% lebih rendah dari yang dilaporkan oleh Hanum et al (2016) berkisar antara 30-43% pada perkebunan sawit umur delapan tahun. Rasio daun/batang sebesar 0,75 pada panen umur 50 hari merupakan hal yang bermanfaat bagi ternak karena daun lebih mudah dikunyah dan dicerna sehingga nutrisi di dalam rumput dapat diserap dan dimanfaatan oleh ternak.…”

The integration of livestock with plantations is one of efforts to support livestock agribusiness. The large potential land area can be used for the development of cattle. However, the low production, nutrient content and digestibility of natural grasses in the plantation are still an obstacle to increase cattle productivity. Therefore, the development of shade tolerant of forages is one of the strategies to improve the quality and production of forages in the plantation area. This paper aims to review the role of Stenotaphrum secundatum as a shade tolerant forage in oil palm plantations in supporting cattle productivity. Biomass production of Stenotaphrum secundatum obtained was relatively high at 42,209 kg DM/ha/yr in oil palm plantations aged 3.5 years, estimated to be able to accommodate cattle of 11.8 AU/ha. With a moderate composition of nutrition, it can improve cattle growth performance with an average body condition score of 3.8. The livestock integration system by developing S. secundatum in the oil palm plantation area has a positive effect because it can reduce fertilizer and weeding costs of 4 million IDR/ha/yr. The average production of fresh fruit bunches (FFB) reaching 19.5 tons/ha/yr. It can be concluded that the role of S. secundatum in oil palm plantations can support cattle productivity and increase palm oil production.

Soybean is useful for tofu, tempe, soy sauce and soy milk. The effective use of fertilizer and organic application can increase soybean productivity. The objective of this research was to study the growth and yield of various soybean varieties on application of phospate fertilizer and organic matter. This research was conducted in North Binjai and Research and Technology Laboratory Agriculture Faculty Universitas Sumatera Utara, Medan on May-September 2016. The method used Randomized Block Design with 3 factors. The first factor is soybean varieties consisting of: (Argomulyo, Dering, Dena, Kaba, Gema, Grobogan and Wilis), fertilization of phosphate (control and 150 kg/ha) and organic material application (control, Blotong 10 ton/ha and POEFBC/Palm Oil Empty Fruit Bunches Compost 10 ton / Ha). The results of this research showed that the seven varieties of soybean had characteristic differences on shoot dry weight, age of flowering, age of harvest, phospate uptake and dry weight of 100 seed. The longest flowering and harvesting age is obtained in Wilis, while the shortest age is Grobogan. The highest uptake of P in Argomulyo with treatment without organic matter and phospate fertilizer. Kaba variety with blotong treatment has the highest dry seed weight.Keywords : Organic Matter, Phosphate Fertilizer, Soybean Varieties

“…Electrical conductivity (EC) was carried out with a multiparameter (Toledo, Seven Excellence) based on methodology proposed by Chi & Wang [15]. Organic matter (OM) was determined by the Walkley & Black method [16], inorganic nitrogen (Ninor) by distillation in micro-Kjeldahl [17] and available phosphorus (Pava) according to Bray and Kurtz method [18]. In addition, atomic absorption spectrometry with an Agilent Technologies 200 Series AA equipment were used for soil samples in order to determine the following elements [19]: sodium (Na), potassium (K), calcium (Ca), magnesium (Mg), Iron (Fe), manganese (Mn), zinc (Zn), copper (Cu).…”

“…In the case of organic matter and electrical conductivity, the reference values were considered those suggested by Masto et al [41] to classify soil as medium saline. In the case of the cation exchange capacity and Ca, the values reported as good for cultivation were taken as it was reported by Hanum et al [17]. Finally, Fe and Zn optimal values were based on those reported in Ortega [42], which are considered as minimal before they cause deficiencies in the crop.…”

The knowledge of the soil quality plays a vital role in the agricultural sector. Despite its importance, there is scarce scientific information concerning this regard. The objective of this research is to develop a methodology to identify and select the most appropriate indicators of Soil Quality Index (SQI) in a region with high agricultural activity. For its conformation, a descriptive statistical analysis and a Pearson correlation matrix were performed and the indicators that showed greater variation were identified using a Principal Components Analysis (PCA). A sensitivity analysis was carried out and the most sensible soil indicators of SQI were identified. This statistical procedure was also used to specify the weights of the indicators in SQI. The variables resulting from the multiparametric statistical analysis were pH, organic matter, sodium, calcium, iron, zinc, cation exchange capacity and electrical conductivity. The robustness of the SQI obtained in this study was demonstrated through simulations carried out by the numerical optimization through simplex method. The Soil Quality Index range obtained (0.54 -0.75) locates Culiacan Valley soils as moderate/high quality.
