Abstract
Cocoa is the main plantation crop in Indonesia after rubber and oil palm. Indonesia’s cocoa production is the sixth-largest after Ghana and Ivory Coast. Cocoa cultivation spreads to almost all islands in Indonesia. However, the largest is on the island of Sulawesi. West Sulawesi is one of the largest cocoa producers in Indonesia. The decline in cocoa production has continued since 2012. One of the causes of the decline in cocoa production is a decrease in acreage and low productivity of the cocoa plant. The current average cocoa productivity is only 797 kg/ha/year. This productivity is very low compared to the optimum productivity, reaching 2,000-3,000 kg/ha/year. One of the causes of low productivity is uneven land suitability. Cocoa is grown on land with a poor land index. This study aims to study the land index in West Sulawesi to develop land suitability for cocoa plants. His research took place in January-August 2020. The collection of representative points consisted of 30 points spread over four districts in West Sulawesi, namely Polewali Mandar, Majene, Mamuju and Mamasa Regencies. The results showed that there was a strong correlation between land index values and cocoa productivity. Each increase in the land index will increase the productivity of specific cocoa plants for the West Sulawesi Region. The highest Land Suitability Index value (53.56) was obtained on land with cocoa productivity of 2,000 kg/ha/year. The lowest Land Suitability Indexvalue is obtained on land with a 700 kg/ha/year productivity.

Authors: Samai Suarna , Muhidin  
Published: July 2021

Abstract
Efforts to reduce weed control costs, especially in minimum tillage land, can be done by reducing the dose of herbicide per hectare, and the addition of urea fertilizer replaces this reduction. The research was designed using a randomized block design with three replications. The treatments were application of glyphosate 1.44 kg ha−1, 1.80 kg ha−1, and 2.16 kg ha−1 in combination with without urea; urea 5 kg ha−1, 10 kg ha−1 and 15 kg ha−1, and application on minimum tillage, full tillage and control. The results showed that the addition of adjuvants from urea and glyphosate could control weeds, especially in reed weeds in the mixing of herbicide glyphosate 1.44 kg ha−1 + urea 10 kg ha−1, while herbicides 1.44 kg ha−1 + Urea 5 kg ha−1 and glyphosate 1.80 kg ha−1 + Urea 5 kg ha−1 have the same control power effectiveness as glyphosate dose of 2.16 kg−1, urea dose of 5 kg ha−1 the effectiveness is equal to 1.80 kg ha−1 + Urea 15 kg ha−1. The herbicide glyphosate disrupts metabolism in plants, causing abnormal growth or even killing weeds. Mixing does not cause poisoning of the corn crop. The use of herbicide glyphosate 1.44 kg ha−1 + Urea 10 kg ha−1 is better based on plant poisoning and corn production. The optimum dose that can minimize the weed population is 8.650 grams, and the combination of herbicide Glyphosate and Urea is effective in controlling weeds with minimum conditions at 1.158 grams of glyphosate and 1.146 grams of Urea.

AbstractSweet sorghum is one of the superior commodities to increase the production of food and energy. Sweet sorghum seeds produce carbohydrates that can be processed into food ingredients, while the sap from the stems and starch in the seeds can be converted into bioethanol through fermentation processes. Sweet sorghum crops tolerant to drought and stagnant water can produce on marginal land and relatively resistant to pests and diseases. This research aims to determine the interaction between sweet sorghum varieties and kinds of organic fertilizer on the growth and yield of sweet sorghum in dryland. The research method is a factorial experiment using Randomized Completely Block Design (RCBD), which consists of two factors, which is sweet sorghum varieties and manure types. The varieties which were used are Kawali and Numbu. The second treatment used is without manure, chicken manure, goat manure, cow manure, and vermicompost. The total treatment combination is ten units, and each combination is repeated three times. The research variables are plant height, stem diameter, leaf area index, fresh stover weight, dry stover weight, sap content, panicle length, number of seeds per panicle, and production per hectare. Data were analyzed using the F test with a 95% confidence level if there is significantly a difference and then followed by the DMRT method at the 5% level. This research shows that the highest production per hectare is sorghum treatments by chicken manure equal 2.64 ton/ha, and this yield is higher than all other treatments.

Published: July 2021

Abstract
The main problem of mangosteen production is yellow latex in the rind and aril of the mangosteen fruit. The yellow latex occurs from the yellow latex channel’s rupture and contaminates the arils or mangosteen rind. The rupture is thought due to the lack of calcium in the epithelial cell walls of the yellow latex ducts. The present study aimed to determine the effect of calcium in reducing yellow latex in the mangosteen fruit. The study was conducted in Luhur Jaya Village, Lebak Regency of Banten Province. The study used a randomized block design, consisting of 6 treatments and 5 replications with treatment P0=control, P1=dose of calcium/dolomite lime 2 kg/tree, P2=dose of calcium/dolomite lime 3 kg/tree, P3=dose of calcium/dolomite lime 4 kg/tree, P4=dose of calcium/dolomite lime 5 kg/tree, P5=dose of calcium/dolomite lime 6 kg/tree. The calcium was given when the mangosteen plant started to flower. From the results, the application of calcium using dolomite (CaMg(CO3)2) reduced yellow latex contamination in mangosteen rind at doses of 5 kg/tree. All doses of calcium applied (2, 3, 4, 5, and 6 kg/tree) reduced yellow latex contamination in arils. The application of calcium with dolomite (CaMg(CO3)2) did not affect fruit weight and dotted on mangosteen.

Abstract
Today’s agricultural business is faced with various obstacles, and cannot be measured to what extent its competitiveness, while the conception of agricultural development that has competitiveness has not been described more operationally and implementable, so that there is a gap between the ideal conception and the actual field. This study activity aims to analyze the competitiveness of Nutmeg spice farming in terms of domestic resource use in Ternate City. Nutmeg farming in Ternate City has a competitive and comparative advantage, this is indicated by PCR and DRCR values that are smaller than 1 (one). The results of PAM analysis on nutmeg farming have no input transfers because they do not use foreign inputs. The NPCI value for all is below one (<1). The value of NPCI is smaller than one, meaning that domestic prices are lower than world prices, so there can be said to be a subsidy policy from the government. Whereas for nutmeg farming. The transfer value of factors for nutmeg is positive, this indicates that there is an implicit tax or transfer from the nutmeg farmer to domestic factor, so farmers have to pay more than the price of the shadow (social).

AbstractSoutheast Sulawesi, which is located in the southeastern part of Sulawesi island, is one of the upland rice producers in Indonesia, although the cultivation in the area is still not optimal because the upland rice productivity is still considered low. Southeast Sulawesi has an extensive dry land area and local upland rice genotypes have good growth and yield potential. This study aimed to determine the differences in the growth of several local upland rice genotypes of Southeast Sulawesi which were cultivated in Kendari City. This paper is still focused on the vegetative growth of the genotypes tested. This research was carried out in Experiment Field 2, Faculty of Agriculture, Halu Oleo University, which is located in Kambu District, Kendari City, Southeast Sulawesi. The research was conducted using a randomized block design (RBD) consisting of 10 genotypes, namely Wagamba (V1), Wangkariri (V2), Momea (V3), Waburi-buri (V4), Konkep (V5), Bakala (V6), Wakawondu (V7), Tinangge (V8), Loiyo putih (V9) and Bombana (V10). Each treatment was repeated 3 times in order to obtain 30 experimental units. The results showed that potential genotypes that can be developed in Kendari City were Wakawondu genotype based on parameters of the number of tillers, plant height, and number of leaves, Wagamba genotype based on leaf width parameter, and Wangkariri genotype based on the flowering age and number of tiller parameter. Based on the overall performances, especially on the number of tillers (one of the most important parameters), in general Wakawondu is the most recommended genotype for further development.

Published: July 2021

Abstract
In the article, the authors give a brief description of EIS REGION, designed to build predictive models of changes in the parameters of biological resources of territories from environmental factors and anthropogenic impacts. On the example of a large region (the Volga basin), a forecast of changes in primary biological productivity under conditions of global climate warming was carried out using EIS REGION. Some variants of influence on bioproductivity of anthropogenic pollution and the level of economic development of the subjects of the region are considered. The authors that in conditions of climate change with an increasing thermal trend, an increase in the primary biological productivity is predicted for all-natural zones of the Volga basin. In this regard, we specifically forecast that an increase in temperature and a decrease in climate humidity will relatively favourably affect the ecosystems of the taiga zone- a zone of lack of heat and excess moisture. The predicted climate change will be less favourable for the forest-steppe and steppe zones, since an even greater climate aridization is expected here.
