Abstract

‘California’ papaya is a newly released papaya cultivar in Indonesia that has a very short shelf-life. Increasing demands in both local and export markets warrant the need for a proper postharvest technology to prolong its shelf-life. This research was conducted to study the effects of fruit coatings (chitosan, KD-112, plastic wrapping), fungicide Prochloraz, and storage temperatures on its fruit shelf-life and quality. Three parallel experiments were conducted with treatments arranged in a completely randomized design of a 2 x 2 x 2 factorial design.  The first factor was chitosan (with and without 1.25% chitosan), or KD-112 (with and without 14% KD-112), or plastic wrapping (with and without one layer plastic wrapping), the second was Prochloraz (with and without 0.67 mL/L Prochloraz), and the third was storage temperature (27-28 and 16-18 ºC). While Prochloraz did not affect fruit variables, cooler temperature and coatings lengthened fruit shelf-life with the best effect shown by plastic wrapping which lengthened fruit shelf-life by 13 days, without affecting fruit qualities. Significant effects of coating and cooler temperature determined their combined effects, with the best effect achieved by applying the three factors that lengthened fruit shelf-life by 11-23 days longer.

Abstract

Plant population is one of key factors in crops yield. The determination of optimum population per area unit needs to be accommodated through the planting space arrangement. This study aimed to know the performance of some soybean genotypes planted with both single and double row planting pattern. The research was conducted in Kendalpayak Experimental Field, Malang from February to May 2017 arranged in split plot experimental design with three replications. The main plot was planting space consisting of single row (40 cm x 15 cm) and double row (60 cm x 20 cm x 15 cm), while the sub-plot was the soybean genotypes consisting of 12 promising lines (Grob/IT-7-7, Grob/Pander-397-6, Grob/IT-17-1, IBK/Argop-276-3, Grob/Pander-395-2, Grob/Pander-428-1, Grob/IT-7-5, Grob/IT-7-2, Grob/IAC-453-7, IBK/ Grob-296-10, Grob/IT-7-3, and Grob/IT-7-1) and 3 cultivars as comparison (Dena 1, Dena 2, and Grobogan). Each experimental unit was set in an area of 10.8 m2. Observation was performed on variables of plant height, number of fertile nodes, number of pods with three seeds, number of pods with two seeds, number of sterile pods, seeds dry weight, pod shells dry weight, weight of 100 seeds, and yields. The results of the research showed that each genotype performed different response to planting space depending on the characteristic of it. Yield obtained from double row planting space was 4.76% higher than that from single row planting space. There were 8 genotypes (Grob/IT-7-7, Grob/Pander-397-6, Dena 1, Grob/IT-7-5, Grob/IT-7-2, Grob/IAC-453-7, Grob/IT-7-3, and Grob/IT-7-1) which were able to produce seeds 2.0 ton/ha, either planted in single row or double row planting space.

Abstract

Melon plants (Cucumis melo L.) are susceptible to disease attacks primarily caused by viruses. One of the viruses often attacking melon plants is Cucumber mosaic virus (CMV). Previous studies have shown that melon callus produced from in vitro culture is detected to have CMV resistance gene (Creb-2). However, the trait of resistance to CMV in that melon (F2) is still segregated. To know the stability of the Creb-2 gene, further research is needed to detect the gene in the differentiated callus. This study aims to  callus induce and callus differentiate melon. Firstly, melon seeds were grown on ¼ MS medium with addition of 2 mg / L 2.4-Dichlorophenoxyacetate and 1 mg / L BAP (Benzyl Amino Purine) to grow callus. Secondly, the callus was differentiated in MS medium with the addition of 2,4-D , BAP and IAA in different doses. 0 mg / L; 0.01 mg / L 2.4-D and 0.1 mg / L BAP, and MS medium with 0.01 mg / L; 0.1 mg / L; 1 mg / L IAA (Iodole Acetic Acid) and 0.1 mg / L BAP. The results showed that callus was successfully differentiated into root and it grew optimally in MS medium with 0.01 mg / L 2.4-D: 0.1 mg / L BAP and 1 mg / L IAA: 0.1 mg / L BAP . Therefore the roots can be used as isolation samples and DNA amplification to detect stability of the Creb-2 gene.

Abstract

The research aims to calculate the water requirement and irrigation interval of maize crop as well as to design water-efficient irrigation application system. The study was conducted on dry land of Palembang city of South Sumatra. The indicator crop used in this study was maize. Daily climate data were taken from Sultan Mahmud Badarudin and Kenten station. The research applied survey method, laboratory analysis, computer simulation and irrigation design. The calculation of water crop deficiency was done using empirical approach by multiplying the potential evapotranspiration value by crop coefficient. Soil water retention characteristic was recorded based on the calculation of the length of water available to plants. Daily rainfall in the field was recorded as water input other than water from irrigation. The combination of soil, climate and plant physiological properties (Agro-pedo-climatic) will result in a water irrigation system in a region. Water balance analysis was developed by the help of computer model (BUDGET model). The result of computer model analysis shows that maize crop in rainy season does not require irrigation. While for the transition period (March-May), irrigation is required for the flowering phase with a total water requirement of 76.5 mm. During dry season (May-July), irrigation is required with water requirement of 198 mm. Irrigation scheduling is set up 9 times with intervals every 7 days at the beginning of growth and 10 days at the middle and end. While the testing under dry climate conditions (El Niño) using rainfall data in 2015 indicates irrigation should be given since March and during planting period (May-August 2015) the irrigation should be applied 12 times with intervals every 5 days at the initial stage and 10 days during vegetative stage.

Abstract

The existence of weeds on sweet corn crops can lead to competition that reduce the yield. The aim of this research was to obtain the optimum crop proportion of corn-peanut plants in suppressing weed growth but not decrease the yield of sweet corn. The experiment was conducted using a single factor field experimental method arranged in a complete randomized block design with 3 blocks as replication. The treatment was the proportion of sweet corn-peanut population consisting of 3 levels, i.e 1:1, 1:2, 1:3, sweet corn monoculture and peanut monoculture as comparison.The results of this research showed that intercropping of sweet corn+peanut with  population proportion of 1:2 can suppress weed growth in on the 9th week (at harvest) without decreasing sweet corn yield.

Abstract

The great eruptions of Mount Merapi in 2010 have drawn a great deal of attention from both national and international media.The month-long eruptions killed more than 200 people, displaced over 100,000 residents, killed over 1,000 livestock and destroyed over 1,000 hectares of productive farming fields. Incidentally, agriculture is one of the livelihood sectors that suffered heavily. Further, it impacted farmers the most as they depend on farming activities as their main source of livelihood. After, the eruption, land management became based on material type and condition of the land.. Principles of land management involve the provision of appropriate environmental needs of plants, the availability of moisture, nutrients, colloidal holding nutrients, and aeration. In short, they entail the technical aspects of recovery after the eruption of plants based on the conditions of the land. Also included are crop diversification (intercropping cultivation, crops rotation, mixed farming, etc) and intensification of yard (horticulture crops, hedge rows); as well as reinforcing of core and source of cattle nutrition, for example gliricedea; fast growing and producing crops are needed but those that need high capital / major costs for planting and care are not required. Furthermore, the concept of post-eruption land arrangements needs to be formulated based on the configuration of the land which is mainly related to local circumstances such as topography, hydrology, meteorology, and natural drainage systems.
