“…Sebagai tanaman tahunan, jati perlu diusahakan pada tanah yang baik agar dapat diperoleh hasil yang optimal. Pengusahaan suatu komoditas, pada lahan yang tidak memiliki kesesuaian tumbuh pada hakekatnya merupakan pemborosan sumberdaya (Hallam et al 2001; Bell 2013), oleh karena seharusnya sumberdaya tersebut dapat digunakan untuk komoditas yang lebih memberikan hasil yang tinggi (Widiatmaka et al 2014).…”

Teak (Tectona grandis Linn f.) produce one of the most desirable wood in the world. Nowadays, fast growing teak resulting from genetically engineered teak have been available. This study aims to look at the relationship between land characteristics and soil classification with vegetative growth of "Unggul Nusantara" varieties of teak. The study was conducted in Ciampea, Bogor Regency. Soil properties were analyzed from three profiles, while the vegetative growth of teak was measured from 2.5-3 years old teak planted on those land. The diversity of soil properties on the profiles were function of the difference of soil parent material as well as its position on the slopes. Three soil profiles of P-1, P-2, and P-3, lying from upslope to the downslope, were classified respectively as Typic Paleudalf, very fine, mix, active, isohipertermic; Typic Dystrudept, very fine, mix, active, isohipertermic; and Typic Hapludult, very fine, mix, semi-active, isohipertermic. Soil of the three profiles were capable of supporting the growth of teak varieties of "Unggul Nusantara". The best grown plant was found on the profile P-1 in the upslope, followed by the plant on the profile P-3 in the downslope, and then the plants on land above the P-2 in the middle slope. Nevertheless, the quality of the teak harvest produced in the three profiles can be categorized as low category. Soil with lime sediment parent material that has a high pH and base saturation is able to provide better growth for plants teak varieties of "Unggul Nusantara".

“…The method has been used in different areas, e.g., in a study of Imhoff et al (2010) to evaluate soil physical properties, and by Schmidt et al (2000) and Topp et al (2013) to evaluate N 2 O emission from agricultural soils. Widiatmaka et al (2014) used this method to establish sustainability criteria in cashew growing areas in Indonesia, while Shatar and McBratney (2004) used a third-grade polynomial model to identify yield response to soil chemical properties.…”

ABSTRACT:The boundary line is a method frequently used to assess the nutritional status of plants when the relationship between the variables under analysis is influenced by other interacting factors. The objective of this study was to propose and test the boundary line model to estimate the nutrient sufficiency range and nutritional status of irrigated muskmelon. The lower and upper limits of the sufficiency range were calculated as a basis for assessment of the nutritional status of muskmelon. Leaf material was collected from 70 muskmelon crop areas in northern Brazil. The nutrient (N, P, K, Ca, Mg, S, Fe, Zn, Mn, B, and Cu) concentrations in the leaf tissue and the respective fruit yield of each area were measured. The proposed model to estimate the boundary line allowed estimation of the sufficiency range of nutrients for irrigated muskmelon. The main growth-limiting factors of muskmelon due to nutritional deficiency were P > N = K, and those caused by nutrient excess were N > Zn = Cu.

“…On the other hand, the land available for production becomes more and more limited due to the population increase, which will also increase the need for land for various uses (Pilehforooshha et al, 2014;Zhang et al, 2014). One of the implications for agriculture is the necessity of selecting agricultural land that has a high level of suitability for cultivation (Widiatmaka et al, 2014(Widiatmaka et al, , 2015a so that higher production can be achieved in each parcel of land.…”

In Indonesia, Java Island still contributes a large amount of the total number of vegetables produced. In this tropical country, vegetables are produced in two different agro-ecological conditions, which are high altitude and low altitude. The rapidly increasing population growth has caused the centre's production of high altitude vegetables on Java Island to be increasingly pressured by other types of land utilization. This study was conducted in one of the production centres of tropical high altitude vegetable crops in the upper slope area of Mts Gede-Pangrango, West Java, covering an area of 78,290 ha. The research objective was to delineate the suitable land that is available for high altitude vegetables crops. In the first step, land suitability was analysed using multi-criteria decision-making methodology. The criteria used include those grouped within the parameters of land, topography, climate and ease of management; criterion consists of sub-criteria. The criteria were weighted using the Analytical Hierarchy Process, while sub-criteria were scored according to their contributions to land suitability. The weights of the criteria and scores of the sub-criteria were used for delineating land suitability in a geographic information system model. In the second step, the land availability was analysed by taking into account the constraints of forest area status designation and the spatial pattern of official land use plan map. Results of both analyses were used to delineate suitable and available land for tropical high altitude vegetables crops. The results showed that the amount of land that was suitable and available for tropical high altitude vegetables crops was 23.7% of the analysed area. The area of suitable and available land that is actually not used yet is 9% of the area analysed, which could be recommended for the expansion of vegetable crops. Land that is suitable and available, either land that is already used or land that is not yet used, could be designated as priority lands to be protected from the pressure of non-agricultural land utilization in order to maintain the sustainability of vegetable availability.
