Hence, this study analyzed cell wall changes in two mealy (Orin and Akane) and three non-mealy (Kiou, Kitaro, Fuji) apple cultivars during ripening. The fruits were harvested for each cultivar at optimum maturity and stored at 20°C for 20 days. The flesh firmness of ‘Kitaro’ and ‘Fuji’ fruit did not change strikingly over the 20 days, whereas that of the other three cultivars, especially ‘Akane’ and ‘Orin’, gradually decreased during ripening. Between the two cultivars with a mealy texture, ‘Akane’ fruit produced extremely low levels of ethylene, whereas ‘Orin’ fruit produced high levels. The water-soluble polyuronide (WSP) contents of ‘Kiou’ and ‘Fuji’ fruit did not change clearly. In contrast, the WSP contents of the other three cultivars, especially ‘Akane’ and ‘Orin’, increased during ripening. In ‘Kiou’, ‘Kitaro’, and ‘Fuji’ fruit, the molecular-mass distributions of WSPs did not change during ripening. Conversely, the molecular-mass distribution of WSPs in ‘Akane’ and ‘Orin’ fruit exhibited downshifts during ripening. These results indicate that solubilization and depolymerization of pectic polyuronides occur during ripening in mealy ‘Akane’ and ‘Orin’ fruit, and that ethylene may not be involved in these changes.","PeriodicalId":13282,"journal":{"name":"Ilmu Pertanian (Agricultural Science)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46703970","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}

Three application rates of the serum were adopted, consisting of 3 mL (3,000 L.ha-1), 5 mL (5,000 L.ha-1), and 0 ml (0 L.ha-1), and represented as treatment. Amaranthus hybridus was transplanted into pots containing 2 kg of 2 mm sieved air-dried soil. Each treatment was replicated seven times to give a total of 21 pots that were laid out in a Completely Randomized Design (CRD). The treatments were applied twice a week starting from the 2nd week after transplanting. The plant growth indices measured were number of leaves, plant height and plant biomass. The results showed that serum positively influenced the number of leaves and plant biomass (4.333 kg to 4.830 kg) compared to the control (3.901 kg). However, the highest value of the plant biomass was found in the 3 mL (3,000 L.ha-1) treated pots, while the microbial colonies of bacteria in soil after serum application were sustained when compared with the control but at a reduced population for Bacillus subtilis. The application of LB. serum slightly improved the soil total organic carbon (320.0 g.kg-1 to 352.0 g.kg-1) and nitrogen (3.102 g.kg-1 to 3.325 g.kg-1) as against, 64.00 g.kg-1, and 0.639 g.kg-1 in the control respectively.

This study aimed to compare the types of P fertilizers of nano guano, nano phosphate rock, and SP-36 with various doses of P2O5 and determine the most effective type. This research was arranged in a completely randomized design (CRD) with two factors. The first factor is the type of fertilizer, consisting of nano guano, nano phosphate rock, and SP-36. The second factor is the dose of P2O5 with four treatment levels, namely 0 kg.ha-1, 50 kg.ha-1, 100 kg.ha-1, and 150 kg.ha-1. The results showed that nano phosphate rock was the most effective fertilizer for maize in Inceptisol.

The disadvantages and advantages of Ca in plants can affect morphology and anatomy in plants. This research aimed to identify the effect of Ca on the anatomical performance of the roots of cocoa plants and determine the optimal dose of Ca for the anatomical characteristics of the roots of cocoa plant. The research was conducted at the cocoa plantation owned by PT. Pagilaran at North Segayung Production Unit, Tulis Subdistrict, Batang Regency, Central Java, in October 2019 – February 2021. The observation of root anatomy was carried out by making preparations, and the plant roots were taken destructively and sliced transversely. The field experiment was arranged using a single factor randomized complete block design. The treatments consisted of without fertilizer application and calcium fertilization at a dose of 100 g/tree/year, 200 g/tree/year, 300 g/tree/year, and 400 g/tree/year. The cocoa clone used was clone RCC 71. The results showed that an increase in the dose of CaCl2 fertilizer up to 400 g/tree/year was generally followed by an increase in the size of the xylem and phloem diameters, the thickness of the cork layer, the thickness of secondary cortex, and the diameter of the stele. The quadratic effect of the dose of CaCl2 fertilizer was observed only on the thickness of the root cambium tissues. Thus, it is necessary to conduct further research to determine the optimal dose of Ca fertilizer for the anatomical characteristics of cocoa roots.","PeriodicalId":13282,"journal":{"name":"Ilmu Pertanian (Agricultural Science)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45786646","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 use of terraces on steep slopes is considered effective in preventing erosion. However, this does not increase agricultural productivity significantly. Therefore, this study aimed to analyze the performance of maize on land with and without terraces as affected by the addition of goat manure and NPK. A field experiment was arranged in a randomized complete block design, consisting of 12 experimental plots that were made on a hill with a slope of 79 % with three replications. Plant tissue samples were analyzed for assessing N, P, and K content. However, soil samples were measured for N, P, K, SOC, pH H2O, EC, CEC, and soil texture. Data were analyzed using analysis of variance and continued with a Post-Hoc test (DMRT at α= 5%). The application of manure and NPK fertilizers significantly improved EC, SOC, N, and P in soil, also N and P content in plant tissues. Goat manure played a role in improving soil properties, while NPK fertilizers played a role in supplying nutrient availability directly to plants. The best performance of maize was on land without terraces and cover crops (sweet potato). Competition for nutrients between maize and sweet potato occurred on land with terraces so that the performance of maize tended to be lower. Soil management on land with terraces needs to consider nutrient management and selection of cover crops so that both can increase maize productivity.","PeriodicalId":13282,"journal":{"name":"Ilmu Pertanian (Agricultural Science)","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47756516","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}
