Conversion of agricultural land into non-agricultural land is one of the major causes of the decline in corn production. Saturated soil culture (SSC) is a cultivation technology that gives continuous irrigation and maintains water depth constantly and makes soil layer in saturated condition. This technology can prevent pyrite oxidation in the tidal swamp. This research aimed to study the effect of temporary fl ooding under saturated soil culture on the growth and productivity of corn. The research was conducted at Karya Bhakti village, Rantau Rasau, Tanjung Jabung Timur, Jambi Province, Indonesia. The experiment used a split plot design with three replications. The main plot is fl ooding condition, consisted of 1) saturated soil condition continuously, from planting until harvesting time (as control), and 2) saturated soil condition from 0 to 10 DAP (Days after Planting) + fl ooding from 11 to 13 DAP + saturated soil condition from 14 to 28 DAP + fl ooding from 29-31 DAP + saturated soil condition from 32 DAP until harvesting time. The subplot is corn variety, “Sukmaraga”, “Bisma”, “Pioneer 27”, and “Bima 20”. “Pioneer 27” had the highest productivity of 9.33 t.ha-1. Corn varieties with moderate tolerance to temporary fl ooding were “Sukmaraga” and “Bisma”, whereas “Pioneer 27” and “Bima 20” are sensitive to fl ooding.","PeriodicalId":33751,"journal":{"name":"Journal of Tropical Crop Science","volume":"45 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79095724","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional breeding of E. elatior is limited by cross incompatibility, poor fruit set and low seed production. In this study irradiation of E. elatior with Gamma ray performed to induce mutation. This study was aimed to increase morphological diversity and to obtain unique morphological characters to increase the aesthetic value of E. elatior as ornamental plants and cut flower. Two genotypes of E. elatior, red and white flowers, were tested. The LD20, LD35, and LD50 were determined following intermittent (split dose) Gamma irradiation with a two-hour gap between each gamma ray shot. Red genotype E. elatior explants were irradiated with dose of 3 + 3 Gy (LD20); 4 + 4 Gy (LD35) and 5 + 5 Gy (LD50); white genotype were irradiated with a dose of 2 + 2 Gy (LD20); 2.8 + 2.8 Gy (LD35) and 3.7 + 3.7 Gy (LD50). Non-irradiated explants were set as control. The results of this study indicated that the increase in dose of gamma ray irradiation changed shoot length and number of leaves in the red genotype per explant as compared to control. Morphological changes occurred in leaf shape at 5 + 5 Gy and 3.7 + 3.7 Gy and formation of variegated leaves at 2.8 + 2.8 Gy and 5 + 5 Gy.

Propagation through plant tissue culture can be an alternative method to produce hybrid melon seedlings in order to fulfill the high demand for uniform seedlings. Our current study was aimed to determine the type of propagation media and the best concentration of picloram for the induction of somatic embryogenesis in melon from young seed explants. The study was expanded to examine the effective concentrations of two of auxins, 2-4 D and NAA, combined with BAP to induce somatic embryogenesis in melon using hypocotyl explants. The experiment was conducted at Plant Tissue Culture Laboratory, Department of Agronomy and Horticulture, Faculty of Agriculture, Bogor Agricultural University. The experiment was arranged in a randomized complete block design with three replications. The first experiment tested three types of planting media (MS, B5, and WPM) and four levels of picloram concentration (0, 0.5, 1.0, 1.5 mg.L-1). The second experiment tested auxin (2,4-D and NAA) concentrations of 0, 1, 2, 3, 4, 5 mg.L-1 and two BAP concentrations, 0 and 1 mg.L-1. The first study showed that no somatic embryos were formed with the media types and picloram concentration tested; the seeds, however, germinated and formed callus. In the second study, there was an interaction between concentration levels of auxin (2,4-D and NAA) and BAP on induction of somatic embryos using hypocotyl explants. Somatic embryo formation can be induced with treatment of 1 mg.L-1 NAA + 0.1 mg.L-1 BAP and 2 mg.L-1 NAA + 0.1 mg.L-1 BAP.

Biomulch is one of the conservation methods that can be used to cover and shield the soil from weeds, prevent soil erosion, and increase the rate of soil infiltration. Arachis pintoi is a perennial, stoloniferous legume crop that has potentials to be used as biomulch. The objective of the research was to study the role of Arachis pintoi in increasing the rate of soil infiltration on a sloping land of oil palm plantation. The research was conducted on the slope land (22.8%) of the Bukit Kemuning Farmer Group, Mersam, Batanghari, Jambi, Indonesia (01036'21\", 102057'11\") from September 2017 to March 2018. The environmental design used in this study was a one-factor randomized block design (RBD) with five ground cover treatments, i.e. natural vegetation, Arachis pintoi, Centrosema pubescens, Pueraria javanica and Calopogonium mucunoides. The results showed that the average growth rate of A. pintoi was 2.47 cm per week, which was lower than the growth of other treatments. The root length of A. pintoi was 50.36 cm at 20 weeks after planting. A. pintoi can be used as biomulch; sloping land planted with A. pintoi had an infiltration rate of 49.30 cm per hour at 20 week after planting, i.e. an increase of 32.47% compared to the infiltration rate with the natural vegetation.Keywords: land cover crop, Centrosema pubescens, Pueraria javanica, Calopogonium mucunoides","PeriodicalId":33751,"journal":{"name":"Journal of Tropical Crop Science","volume":"28 6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80263232","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The closed bottle culture is usually kept in a temperature and light controlled environment which is lower and of different quality from the natural sunlight, resulting in high relative humidity and no air exchange inside the bottles. Explants produced in vitro have malfunctioned stomata, undeveloped cuticles and lower leaf chlorophyll levels, and hyper hydration of the plantlets. Photoautotrophic tissue culture is micro propagation without or with a reduced sugar level in the culture media, so the growth or accumulation of carbohydrates of the explants is dependent fully upon photosynthesis and inorganic nutrient uptake. This method is usually combined with ventilation or CO2 enrichment, and recently, with incorporating porous materials such as vermiculite, gum or paper pulp to the agar media to promote better root system of the explants.

The experiment was arranged in a randomized complete block design (RCBD) with a single factor and three levels of planting system, i.e. conventional ‘Surjan’ system without mulch, one line spray hose with mulch, and two lines spray hose with mulch, with five replications. The result showed that shallots production using of polyethylene mulch and two-line spray hose had higher yields than the conventional method. In addition, this system is more efficient in terms of labor requirement.
