Chaya (Cnidoscolus aconitifolius (Mill.) I.M. Johnst.) is a perennial leafy vegetable. Since the leaf blade is the most crucial component of the Chaya, it should be advantageous to estimate the leaf area non-destructively. This research aimed to (a) develop a beneficial non-destructive model for leaf area estimation, and (b) ascertain the impact of stem cutting diameter when used as planting material on chaya growth rate. The results demonstrated that utilizing the length x width (LW) of the middle lobe as the predictor and the zero intercepts linear regression LA = 1.679 LW with R2=0.947 determination coefficient was the most dependable model for Chaya plant leaf area estimation. The stem diameter, which ranged from 9.9 to 17.3 mm, had affected the shoot length, number of leaves, and canopy area between 5 and 7 weeks after planting (WAP). The variations in growth metrics diminished along with the age of plants. The diameter of the stem cutting used as planting material had no effect on the fresh weight of young edible shoot tip at 11 WAP. On Chaya plants that were cultivated with larger stem cutting diameters, the fresh leaf weight at the branch tips was heavier.

Despite being one of the most important staple food consumed by more than half of the world population, the development of red rice still lacks behind the regular white rice. In Madura, most farmers still use their local landraces with red pericarp. Since most of the growing season is dependent on rainfall, those landraces are expected to provide some useful genes related to drought tolerance. This research aimed to select drought-tolerant accessions candidates of red rice derived from pure lines selection at early stages using PEG 6000. A randomized complete block design was used with two factors and three replications, the first factor was red rice genotype and the second factor was two levels of PEG 6000 concentration (0% and 25%). The results showed that there were different responses in all genotypes used in terms of their responses to PEG 6000 screening. Seedling length, seminal root length, shoot length, seminal root dry weight, and shoot dry weight were reduced by the application of PEG 6000 compared to non-PEG 6000 media. Two genotypes had a better response to PEG 6000 treatment compared to check tolerant (Salumpikit), and these are expected to become a valuable resources for further breeding activities.

Watermelon plants cultivar ‘Kinaree 457’ were grown in plastic house under natural daylight only (control) or with nightly LED supplementary lighting for 6 h (6:00 pm-12:00 pm) or 12 h (6:00 pm-6:00 am) starting from transplanting up to fruit harvest. Plant height, leaf chlorophyll content and fruit yield significantly increased in response to 6 h supplementary LED lighting. Fruit mass, size (length x width) and flesh thickness at 6 h LED treatment were about 2.3 kg, 19.3 ×15.7 cm, and 15.7 cm, respectively, while the fruit of control had 1.7 kg, 16.0 × 14.3 cm, and 13.8 cm, respectively. No significant treatment effect was obtained on peel thickness, flesh color L* and b* values, juice pH and total soluble solids. However, 6 h LED treatment resulted in lower reddening flesh (lower a* values), firmness and higher titratable acidity relative to the control, suggesting the need for improvement in cultural management. Furthermore, multivariate statistics of principal component analysis (PCA) performed on physico-chemical quality revealed the variations among watermelons from lighting and control treatments regardless of lighting hour.
西瓜品种“Kinaree 457”在塑料房中仅在自然光下（对照）或夜间LED补充照明下生长6小时（下午6点至12点）或12小时（早上6点至6点），从移植到果实收获。在补充6小时的LED照明下，株高、叶片叶绿素含量和果实产量显著增加。6 h LED处理的果实质量、大小（长x宽）和果肉厚度分别约为2.3 kg、19.3×15.7 cm和15.7 cm，而对照的果实质量分别为1.7 kg、16.0×14.3 cm和13.8 cm。处理对果皮厚度、肉色L*和b*值、果汁pH值和总可溶性固形物没有显著影响。然而，与对照相比，6小时的LED处理导致较低的果肉变红（较低的a*值）、硬度和较高的可滴定酸度，这表明需要改进培养管理。此外，对理化品质进行的主成分分析（PCA）的多元统计显示，无论光照时间如何，光照处理和对照处理的西瓜之间存在差异。

This study was carried out in an area cultivated with durian in Gua Musang, Kelantan with a soil series of Rengam-Jerangau. The objective of this study was to determine the physicochemical properties of soil cultivated with durian at different elevations and samplings. The soil composite sampling was determined at three elevations (top, middle and bottom elevation) marked using GPS coordinate with two different depths (0-15 cm and 15-30 cm). The United States Department of Agriculture (USDA) of the soil texture is clay with bulk density ranging between 0.98 to 1.11 g/cm3. Significant parameters at alpha value of 95% include total carbon content (0.903% until 1.389%), total sulphur content (0.059% to 0.100%), exchangeable bases calcium, potassium and sodium at 3.520 cmolc/kg to 5.582 cmolc/kg, 0.380 to 0.581 cmolc/kg and 0.101 to 0.155 cmolc/kg respectively. From the significant parameters, only exchangeable potassium was affected by the by both elevation and depth of the sampling while the other parameters were only affected by the elevation. As some of the nutrients had been classified as low, extensive measures need to be done for healthy growth performance.

As an export commodity, rubber is a major contributor to Indonesia's foreign exchange. Regarding the increase in rubber production, a study on combinations of growth regulators and rubber clones has been carried out based on plant growth and anatomical characteristics during the immature plant period. This research is conducted for eighteen months at the KSO Karang Inong plantations, PTPN-I, and PTPN-III, East Aceh District, using five clones. This study adopts a nested design with three factors: clones, Growth Regulators (GRs), and paclobutrazol. The clones used are PB 260, IRR 104, IRR 112, IRR 39, and 105. The GRs combination factor between IAA and Kinetin consists of seven levels and three levels of paclobutrazol. The results show that the rubber clones PB260 and IRR105 give higher stem girth and plant height than the other clones when applied with GRs at six different levels. The most expansive leaf area is found in clone IRR 104 compared to other clones. In addition, paclobutrazol affects plant height. Applying paclobutrazol can reduce plant height for all clones but increases stem girth, skin thickness, number and diameter of latex vessels, and total chlorophyll at 46 months after treatment.

Avocado cv. Cipedak is a superior cultivar that match the preferences of Indonesian consumers. However, it has several weaknesses, such as low edible portion, thin skin, and short fruit shelf life. One effort to improve the character weakness is by mutation breeding using gamma ray irradiation. Induction of mutation by gamma ray irradiation at a dose of 10 Gy was conducted on Cipedak avocado shoots in October 2021 which produced 13 first generation avocado mutants (M1). Observation on leaves morphological characters and DNA analysis were needed to find out the changes level of genetical diversity. The research was conducted in Cukurgondang Research Station and Molecular Laboratory of Indonesian Tropical Fruits Research Institute from January to March 2022. The plant material used involved 13 M1 progenies and cv. Cipedak. The material used were 20 weeks old grafted plants. The observed variables were macro and micromorphological characters as well as DNA-RAPD analysis. The results showed that there were phenotypic and genotypic changes in 13 M1 avocados seedlings. The coefficients of differences on macro and micromorphological characters were up to 33% and 28%, respectively and the coefficient of difference for DNA-RAPD analysis was 74%.

Land and water resources, climate change, and disaster risks significantly affect the agricultural sector. An effective solution for growing crops to improve productivity and optimize the use of resources is through controlled-environment agriculture (CEA). Evapotranspiration (ET) is an important greenhouse crop attribute that can be optimized for optimum plant growth. Light intensity and radiation are significant for controlling ET. To address this challenge, this study successfully determined the properties of optimum artificial light for minimum evapotranspiration rate of head development-stage and harvest-stage lettuce under light-period and dark-period using genetic programming and bio-inspired algorithms namely, grey wolf optimization (GWO), whale optimization algorithm (WOA), dragonfly algorithm (DA), and moth flame optimization (MFO). MFO provided the optimized global solution for the configured models. Results showed that head development-stage lettuce requires higher light intensity with lower visible to infrared radiation ratio (Vis/IR) than harvest-stage lettuce when exposed to light. On the other hand, harvest-stage lettuce requires higher light intensity with lower Vis/IR than head development-stage under dark-period respiration reaction. Findings of this study can be utilized in growing and improving yield crops in controlled-environment agriculture.

Sugar is one of the staple food commodities that has an important role in the Indonesian economy. The high demand for domestic sugar has resulted in the inability of sugar factories to meet the demand for sugar consumption because domestic sugar production is still low. This is due to decreased land area and productivity, low sugar yield rates, and low factory efficiency. This paper describes the improvement of sugarcane cultivation to the process of making sugar to support national consumption. The article uses a systematic review method on the latest sugarcane research and reports the conditions directly on the plantation. The results show that the existing sugarcane supply is still less than the factory's demand, so the factory worked inefficiently. Even though the factory has new machines and technology to produce good quality sugar with a capacity of 4,600 TCD, companies can take a coaching approach to the surrounding community to carry out sugarcane cultivation and provide financial support to the surrounding community. Based on the reality of low production and factory efficiency, the government needs to support the sugarcane cultivation system through farming production systems, improving factory machine capacity and labor for sugarcane estate in the global market era.

Fly ash is the residue of coal combustion that can potentially be an ameliorant. Unfortunately, its use is limited by government regulations that are classified as hazardous and toxic materials. This study examines the effectiveness of fly ash and cow manure as an ameliorant for Ultisols. The experiment was carried out by two factors, i.e., the dose of fly ash, namely 0, 50, 100, and 150 t/ha, and the quantity of cow manure, i.e., 10, 20, and 30 t/ha. The results show that fly ash and cow manure could be ameliorants for low-pH soils such as Ultisols. The suitable dose of fly ash and cow manure as ameliorants in this study are 50 t/ha and 20 t/ha, respectively. Increasing the amount of fly ash caused a decrease in the growth of water spinach, plant height, number of leaves, fresh plant weight, root length, and dry weight of the root. In addition, fly ash increased pH 6.66-7.30, total P 31.74-52.21 mg/100 g, and total K 16.19-25.75 mg/100 g.

Unfortunately, its use is limited by government regulations that are classified as hazardous and toxic materials. This study examines the effectiveness of fly ash and cow manure as an ameliorant for Ultisols. The experiment was carried out by two factors, i.e., the dose of fly ash, namely 0, 50, 100, and 150 t/ha, and the quantity of cow manure, i.e., 10, 20, and 30 t/ha. The results show that fly ash and cow manure could be ameliorants for low-pH soils such as Ultisols. The suitable dose of fly ash and cow manure as ameliorants in this study are 50 t/ha and 20 t/ha, respectively. Increasing the amount of fly ash caused a decrease in the growth of water spinach, plant height, number of leaves, fresh plant weight, root length, and dry weight of the root. In addition, fly ash increased pH 6.66-7.30, total P 31.74-52.21 mg/100 g, and total K 16.19-25.75 mg/100 g.","PeriodicalId":44658,"journal":{"name":"Agrivita","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2023-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45713273","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}

Applying organic fertilizer and intercropping systems are among the techniques for preserving land sustainability in organic vegetable production systems. In organic vegetable production, the use of liquid organic fertilizer has been suggested in addition to the use of solid organic fertilizer. This study evaluates how growth and yields of sweet corn and peanuts grown utilizing row intercropping respond to different vermicomposting dosages. A factorial experiment is arranged using a split-plot design with three replicates. The main plot is vermicomposting dosages; 5, 10, 15, 20, and 25 Mg/ha, and the sub-plot was the applications of liquid organic fertilizer, not fertilized and fertilized with liquid organic fertilizer. Results show that the application of liquid organic fertilizer elevated plant height and leaf area, length, diameter, and weight of husked ears of sweet corn. Vermicomposting increased plant height, husked ear length, husked ear diameter, and husked ear fresh weight of sweet corn. Twenty Mg/ha is the best dosage for producing sweet corn intercropped with peanuts. However, using vermicompost and liquid organic fertilizers did not increase the growth and yields of peanuts. Evaluation of nutrient uptakes by intercropped crops, sweet corn, and peanut, in organic production systems, should be the subject of further study.
