Abstract

Overcoming the Failure of Fruit-set by Removing Former Flower Stem and Shoot on Salak Gula Pasir Fruit (Salacca zalacca var. Gula Pasir). This research aimed to overcome the failure of fruit-set by removing former flower bunch and shoot on salak gula pasir (Salacca zalacca var. Gula Pasir). This research was a factorial experiment, designed using randomized completely block design with 2 factors. The first factor was removal of former flower bunch, consisted of 2 levels (removed and not removed), and the second factor was removal of shoot, consisted of 2 levels (removed and not removed). Thereby, there were 4 treatments combination and replicated 7 times so that 28 plants was required. The result of the research showed that the greatest percentage of fruit-set (80,15%) was obtained on the shoot removal treatment, whereas the fruit-set of the treatment on which shoot was not removed was 60,34%. On the removal of former flower bunch treatment, there was no significant difference on removal and not removal treatment between the percentages of fruit-set.

Abstract

Applications Remote Sensing and Geographic Information System for Mapping of Superior Commodities in Badung District. Superior commodity is one of the conditions in the development of agricultural areas included in (Regulation of the Minister of Agriculture No. 56 of 2016). As for the development of food crops agriculture is based on land suitability classes found in technical guidelines (Ministry of Agriculture, 2017). The two regulations require that each Province develop a master plan for developing agricultural commodities, which is based on superior commodities and land suitability classes. Quantitative and qualitative methods include: (1) identification and interpretation of land use using satellite imagery, (2) field surveys, (3) re-interpretation of satellite images, (4) Location Quotient (LQ) analysis for competitive superior commodities and Shift Share Analysis (SSA) for comparative advantage, (5) Mapping of superior commodities and land suitability of food crops. The use of paddy fields in Badung Regency is 9069.11 ha, moor (898,797 ha), and mixed gardens (3898,615 ha). Competitive superior commodities (LQ) for: (1) paddy rice, located in Abiansemal, Mengwi, North Kuta and Kuta Districts, (2) corn, peanuts, sweet potatoes and cassava in Petang District, (3) soybeans and green beans in Mengwi District. Comparative superior commodities (SSA) of paddy rice are found in the Districts of Petang and Mengwi. While sweet potatoes in Abiansemal District and cassava in Petang District. Potential agroecosystem suitability classes for food crops and secondary crops in the study area are generally classified as very suitable (S1) except in the Petang District which is quite suitable (S2-t, rc1) with a low temperature limiting factor and a rough texture. Increasing the suitability class of paddy and palawija requires fertilizing and adding organic materials to increase production.

Abstract

Diversity and parasitization of egg parasitoid of Leptocorisa acuta on various rice cropping pattern. Study on parasitoid diversity and their parasitization on various rice cropping pattern was conducted during April - October 2012. Exploration of egg parasitoids was conducted by collecting host eggs from rice field in Lombok Island. Sample of Insect were collected by hand. Two species have been identified, namely Ooencyrtus malayensis and Hadronotus leptocorisae. The result showed that eggs of both parasitoid were distributed in all locations with composition 50%. Generally, three times rice cropping pattern showed higher rate of parasitization (31,45%) compared to two times (22,69%) and once cropping pattern (18,03%). Parasitoid and diversity index were similar in different time, although the tend to increase linearly with the rice growth. The Shannon diversity index H’ between 0,24-0,30. Domination index 0,62-0,51, evenness index (E) 0,35-0,43. The result suggest that parasitoid diversity and parasitization is depend on many factors, including rice cropping pattern.

Abstract

Some Biological Soil Properties of Orange Orchard (Citrus nobilis Tan)under Monoculture and Intercropping System with some Vegetable Cropsin Sekaan Village of Kintamani Districts. Orange fruit is of economically importantcommodity in Bali. The fruits mostly produced in Bangli Regency including KintamaniDistrict under intensified monoculture and intercropping with vegetable crops. Those systemspredicted contribute to variation of soil biological properties as the results of differences inmagnitude of agrochemicals that being used. A research about soil biological properties oforange orchard land was conducted in Sekaan Village of Kintamani on November 2015 -March 2016. The purpose of the study was to differenciate the soil biological propertiesamong the common cropping pattern applied in the study area, namely: monoculture oforange, and either intercropping of orange with cabbage (Brassica oleracea), tomatoes(Solanum lycopersicum), chilli (Capsicum annum L.), or cucumber (Cucumis sativus). Threereplications of rhizosperic soil samples were collected from each planting systems andproceed for selected soil analysis. The measured parameters were soil pH, organic-C, as wellas the respective total population number of soil microorganisms, fungi, Gram (+) and Gram(-) bacteria, and also soil respiration. The results showed that total population number of soilmicroorganisms and total fungi were significantly higher on intercropping compare tomonoculture systems. No significant different of those present among soils that cultivatedwith different vegetable crops. In contrary, no differences were also observed for both soilrespiration value and total number of G (+) and G (-) bacteria among soils differing incropping pattern.

Abstract

Utilization Compost of Durian Shell to Reduce Dose of N Inorganic Fertilizer in Green Cabbage (Brassica junceae) Production. The high public demand for organic products are not comparable with the level of production. One of alternative producing agricultural healthy products is using agricultural waste as organic fertilizer for crop production. Durian shell can be used as an alternative material to make organic fertilizer. The study said that the durian shell can be used into useful organic fertilizer for plants and improving soil chemical properties. Based on this potential, research on the use of organic fertilizer from shell of durian need to performed. The results indicate that the solid organic fertilizer durian shell contains 14.6% C- organic, 1.69% N, 0.16% P2O5, and 1:20% K2O. The research aims to determine the effect of organic fertilizer from shell of durian and test their effectiveness in reducing the dose of inorganic N fertilizer on growth and yield of green cabbage (Brassica junceae). This research was conducted with randomized complete block design at the Experimental Garden Trilogy University, Jakarta. Research in the field include the dosage of organic fertilizer (0, 10, and 20 t / ha) and inorganic N fertilizer (0%, 50%, 75% and 100% of the dose recommendation of 250 kg / ha). The results showed no differences plant growth in all treatments. Fresh wet of shoot in the treatment of 20 tons of organic fertilizer + 50% inorganic fertilizer dose did not differ significantly by treatment with 20 tons of inorganic fertilizer + 100% inorganic fertilizers. This result conclused the application of organic fertilizer durian shell is able to reduce the dosage of inorganic fertilizer up to 50%.

Abstract

Analysis of Relationship Between Crop Density and The Balancing of Both Soil Nitrogenand Phosporus in Verticulture System of Mustard Green (Brassica juncea L) and Kale(Ipomea reptana). The relationship between crops density and the balancing of both soilnitrogen and phosphorus in verticulture system remained to be important issue. A glasshouseexperiment had carried out from October 2014 to March 2015 in order to determine (1) theoptimum population density of both mustard greens (Brassica juncea L) and kale (Ipomeareptana), (2) soil total-N or available-P balance, and (3) the relatiohships between plantspopulations and soil nutrients balance. A split plot experiment under complete block designwas applied to examine the effect of the main plot (crops type i.e. mustard green and kale) andsub plot (crops population i.e 10, 15, 20,25, and 30 crops per planting container 0,12 m2 insize). The results showed that no optimal crops population density had achieved. Themaximum crops population was 30 for both mustard greens and kale. The soil total-N balancewas negative while these was positive for soil available-P balance of P and N negative. Alogarithmic relationships was calculated between soil total-N balance with mustard green,while linier patterns were significant for soil-N balance with kale and available-P balancewith both mustard greens and kale.
