The need for bananas in Bali far exceeds the production. To obtain optimal production according to their genetic potential, the development of banana cultivation should be preceded by a land suitability evaluation study. This study aims to evaluate the land suitability based on agroecological parameters such as rainfall, altitude, dry month, slope, and considering current land use. The results showed that 257.467 ha or 46.16% of the area of Bali Province has the potential to be planted with bananas. Buleleng Regency has the widest area for the development of banana plants, followed by Karangasem, Tabanan, Jembrana and Bangli. Denpasar town has the smallest suitable area. Based on the observed agroclimate parameters, slope is the most severe limiting factor in banana cultivation, while rainfall, altitude, and dry months are not significant limiting factors. Recommended land use for the development of banana plants is garden, grass, rain-fed rice field, scrub, bare land, and moor.

This study aims to: (1) to know the suitability of the land for the development of several fruit horticultural commodities in the Sub-district of South Kuta, (2) determine the suitability of land in agroecosystem and its limiting factors, (3) provide ecommendations for land management in the study area. The study used a field survey method with the determination of observation samples carried out in a stratified purposive sampling with land units as the strata. Land quality/characteristics as a determinant of land suitability observed include: annual mean temperature, water availability; rooting media; availability of oxygen; nutrient retention, CEC, BS, pH, and organic matter; nutrients available; erosion; flood hazard; land preparation. Land suitability assessment is done by matching the land quality with the growing requirements for the plants evaluated. The results showed that the actual land suitability for food crops of fruit horticulture (citrus, mango, starfruit, banana, sapodilla, grape, klengkeng, papaya, grain guava, guava, jackfruit, soursop, avocado, srikaya, breadfruit and pineapple) belonged according to conditional marginal suitable (S3), until not appropriate (N) with the quality of the land as a limiting factor are: rooting media (effective depth of soil); land preparation (surface rocks and rock outcrops); erosion hazard; and nutrient availability (especially N-total and P-available). The assumption is that some land quality/characteristics that are as limiting factors can be improved, then the suitability of the potential land is quite suitable (S2) to marginal suitable (S3) with the quality/characteristics of the land as a limiting are: availability of water (long dry months), rooting media (effective depth), land preparation (surface rocks, rock outcrops), and nutrient retention (rather high soil pH). Increased land productivity in the study area can be done by improving land management by providing inputs such as: the addition of sufficient organic material, adition of fertilizer containing elements of N (ZA), and fertilizer containing elements of Potasium (SP36), taking conservation measures in the form of making terraces on sloping lands.

The study on The Role of Organic Matter on Improvement of The Properties of Kusamba Beach Sand Soil, Dawan Sub-District, Klungkung Regency, Bali For Watermelon (Citrullus lanatus Tunb) Cultivation was conducted in the green house of Agriculture Faculty, Udayana University, Bali. The aim of this study was to determine the role of organic matter in the soil properties of beach sand (Entisol type) to increase crop productivity of watermelon. The research used pot experiment with completely randomized design (CRD) method. The treatments used was organic fertilizer of waste cattle with base fertilizer (N, P, K). The dosage of organic fertilizer were: P0 (20% of the weight of soil); P1 (40%); P2 (60%), and P3 (80%). Each treatment was repeated three times, so in total were 12 pots treatment. Organic matter can decrease bulk density, soil permeability, and increase the total porosity of the soil. It was also able to increase total nitrogen, availability P in soil, dry weight of crop and the weight of the fruit at harvest. The highest bulk density was at P0 and the lowest was at P3 or decreased by 23.17%. The soil porosity increased by 7.98%, while the soil permeability decreased by 26.29%. The highest of total Nitrogen and P availability at treatment P3 which increased by 100% and 135.33% repectively when compared with P0. The dry weight of crop and weight of fruit at harvest increased of 48.81% and 97.70% when compared with treatment of P0.

Evaluation of land suitability to increase the productivity of degraded lands in the Unda watershed aims: providing a database of land suitability for land use planning in support of sustainable agricultural development, providing spatial information, and recommendations in accordance with the land use plan of inhibiting factors that exist. Identification of characteristic land quality evaluation survey carried out by the method of land with exploration area of research followed by soil sampling at some sample of land units. Land suitability classification using the criteria of the Technical Guidelines for Evaluation of Land For Agricultural Commodities of Soil Research Institute (2003) is by matching between the haracteristics of the land with the requirements of growing plants was evaluated. Types of agricultural crops that are evaluated include plantation crops and food crops hotikultura fruits. Suitability actual land (land suitability based on survey data) are mostly classified as unsuitable (N), and marginally suitable (S3). Qualities/characteristics as the land that is the main limiting factor, among others: quality of land erosion, slope, water availability, temperature, rooting media (soil texture and coarse material). Sustainable land use planning can be recommended with agroforestry, accompanied by vegetative conservation measures because it is cheaper and easier to be carried out by farmers. Recommended cultivation effort is a combination of timber plants with horticultural crops of fruits with the provisions of at least 40% must be enclosed timber. Plant timber that can be developed between the other plants that are not too heavy canopy.

Forage is one of the supporting factors in planning animal production. Climate condition is one factor which influence forage production. This research attempted to map the class suitability of climate for seven forage species in Bali province and to analysis the level of vulnerability toward climate changes by using Geography Information System (GIS). The results showed that four from seven species observed have class suitability with climate S1. Rain climate factor was the important factor which was influence the climate unsuitability of forage in Bali province. The effect of climate change, such as La Nina 1998 caused positive and negative impacts towards the distribution of class suitability of climate at that year. The incident of La Nina caused the reduction of area of class suitability of S1, S2, and N climate, meanwhile increase the area of class suitability of S3 climate. On the other hand, some location of climate suitability class also changed due to climate change.
