One way is by utilizing existing land without having to open new oil palm plantation areas with replanting. This study aimed to analyze the effect of fertilization frequency on different tillage and to get the best fertilization frequency on different tillage on leaf nutrient levels and growth of oil palm plants. This research experimented with a split-plot design (SPD) with a randomized block basic design. The factors tested in this study consisted of the main plot, e.g., tillage (No tillage, 1 time of tillage, 2 times of tillage) and subplots, e.g., the fertilization frequency (D1: 5 times frequency of NPK fertilization D2: 4 times frequency of NPK fertilization D3 : 3 times frequency of NPK fertilization). The two factors were combined, and 12 treatment combinations were obtained. Each treatment combination consisted of 3 groups, totaling 36 experimental units. Each experimental unit consisted of 2 plants, so 72 plants were obtained. The data obtained were analyzed using variance and further tested with the honest significant difference test (BNJ) at the 5% level and advanced test analysis using the Satker application (SAS). This study showed that NPK fertilization with a frequency of 2 times in 2 times tillage increased vegetative plant growth (increased stem circumference). The main plot of tillage two times increased leaf nutrient content (leaf N content) and plant vegetative (plant height gain and stem circumference increase). NPK fertilization with a frequency of 2 times increased plant growth (increased stem circumference).","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127237074","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}

Increasing production yields can also be done by means of fertilization using the right dose. The main function of fertilizer is to provide or add nutrients which are sometimes available in small quantities, or even not available at all in the soil. Organic chicken manure and inorganic phosphate fertilizers contain various types of nutrients and substances needed by plants. For this reason, it is necessary to find the appropriate dose used to obtain optimal growth and yield of eggplant plants. Research Objectives To determine the dose of chicken manure and phosphate fertilizer on the growth and yield of eggplant (Solanum malongena L). To determine the effect of chicken manure doses and phosphate fertilizer doses and the best interaction between chicken manure doses and phosphate fertilizer doses on the growth and yield of eggplant (Solanum malongena L). The experimental design used in this study was a factorial randomized block design (RBD) consisting of two treatment factors, namely:  Factor I: Dosage of chicken manure (A) consisted of 3 levels, namely: A0= Kontrol,   A1= 4 kg/plot (6 ton/ha), A2 = 6 kg/plot (8 ton/ha).  Factor II:  P0=  Kontrol,  P1= 4,5 g/plot,  P2= 9,0 g/plo, P3= 13,5 g/plot. The results showed that the dosage of chicken manure was significantly different for plant height, number of primary branches, number of sample planting fruit, sample planting production and production per plot. The best dose of chicken manure in this study was A2 (6 kg/plot). Phosphate fertilizer dosage treatment was significantly different for plant height, number of primary branches, number of sample planting fruit, sample crop production and production per plot. The best dose of NPK fertilizer in this study was P3 (13.5 g/plot).

Field tests for this study have been conducted at the ATP Ministry of Research and Technology in South Sumatra. The experiment was run across two growing seasons: the dry season (May through September 2011) and the rainy season (January–April 2012). The equal split-split plot design is used for the study's two growing seasons. The central conflict concerns the application of chemical fertilizer at the following rates: P1: 50% standard dose of ATP (200 kg urea, 50 kg SP36, and 25 kg KCl ha-1), and P2: 25% standard dose of ATP (100 kg urea, 25 kg SP36, and 12,5 kg KCl ha-1). Treatment of several biological fertilizer subplots: H0: no biological fertilizer (control); H1: mycorrhiza; H2: bacterial phosphate solvent. The treatment of children plot uses a variety of corn strains with effective nutrient selection outcomes, including strains B41 (G1), L164 (G2), S219 (G3), and variations BISI 816, as the genotype comparison (G4). Three times each was used for each combination of treatments. The results of the two investigations indicate that strain B41 can produce adaptive growth based on the growing season, is more resilient to drought stress, and may be able to produce more at lower doses of chemical fertilizer while being comparatively stable. A combination of chemical fertilizer at the 50% standard dose of ATP and mycorrhizal fertilizer, along with strain B41, has the best impact on the growth and yield of maize on marginal dryland. Mycorrhizae fertilizer at various levels of low doses of chemical fertilizer can increase the growth and yield of maize in two different cropping seasons. All of the examined maize lines generally showed the ability of the bacteria connected to mycorrhizal and phosphate solvents to enhance nutrient absorption","PeriodicalId":296594,"journal":{"name":"JURNAL AGRONOMI TANAMAN TROPIKA (JUATIKA)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125670525","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}

This study aimed to determine the potential of mushroom Baglog waste compost by adding FMA to groundwater spinach growth (Ipomoea reptans Poir). This study used RAK to treat compost, compost+AFM 10g, compost+AFMA 20g, and compost+AFMA 30g. The study results indicate that Baglog waste compost and FMA have not been able to interact well on the parameters of tendril length, wet weight, and dry weight, as shown by the results that are not significantly different from compost treatment without FMA. Even so, compost waste has the potential to be used as fertilizer or media because it already has physical quality conforming to SNI. Adding FMA to mushroom Baglog waste compost is recommended because it can potentially increase plants' growth rate.
