Sweet corn is a horticultural crop that is widely cultivated and consumed by Indonesian people. Meeting the demand for sweet corn is still reliant on imports; therefore, increasing production by improving soil properties through proper fertilization. Cow manure with a content of N 2.33%, P 0.61%, and K 1.58% is able to add nutrients to the soil. This research aimed to obtain an optimum dose of organic fertilizer for sweet corn growth and yield. The doses of cow manure consisting of 5 levels: control, 10, 20, 30, and 40 tons ha⁻¹ were assigned in the randomized complete block design with 5 replications. Data analysis deployed analysis of variance (Anova) at 5% level, and if there were significant differences, it would be proceeded to Duncan Multiple Range Test 5% and orthogonal polynomial. The results showed that a dose of 20 tons ha⁻¹ was able to increase growth in plant height, stem diameter and number of leaves by 12.92%, 26.29%, and 15.67%, respectively, compared to the control. A dose of 35 tons ha⁻¹ can produce a weight of cob-husk and cob without-husk per plot, respectively, 4.38 kg plot⁻¹ and 2.64 kg plot⁻¹, and a productivity of cob-husk of 5.30 tons ha⁻¹. A dose of 38 tons ha⁻¹ can produce a cob without-husk productivity of 3.29 tons ha⁻¹.

Background: Indigofera tinctoria, commonly known as true indigo, is a plant widely used in the textile industry for its natural indigo dye, which produces a rich blue color for fabrics. I. tinctoria, known for its natural bluish-purple dye, generates 10% dye and 90% waste during extraction, requiring effective waste management. This study aimed to optimize organic fertilizer and mycorrhiza doses from I. tinctoria waste for enhancing soil fertility in arid regions. Methods: The study was conducted from May to December 2020 in Puron Village, Bulu District, Sukoharjo Regency. A factorial Completely Randomized Block Design (CRBD) with 2 factors was employed. The first factor consisted of 5 levels of I. tinctoria organic fertilizer treatments: 0, 100, 200, 300, and 400 g per plant. The second factor included 3 levels of mycorrhiza treatments: 0, 10, and 20 g per plant. Variables observed included mycorrhizal infection on roots, plant growth rate, and yield (fresh leaf and shoot weight of I. tinctoria ). Data analysis utilized ANOVA at a 5% significance level followed by Duncan Multiple Range Test (DMRT). Results: The results indicated that organic fertilizer from natural dye waste at a dosage of 200 g per plant increased the percentage of mycorrhizal-infected roots and boosted shoot weight by 63.27% at 8 weeks after planting (WAP). Mycorrhiza at 10 g per plant increased mycorrhizal infection percentage and enhanced shoot weight by 45.98% at 4 WAP. The combination of I. tinctoria extraction waste organic fertilizer at 200 g per plant and mycorrhizal at 10 g per plant showed interaction, significantly increasing the growth of root nodules of I. tinctoria by 84.04% at 12 WAP. Conclusion: The integration of organic fertilizer derived from indigo dye waste and mycorrhiza presents a promising strategy for enhancing I. tinctoria growth and productivity. Novelty/Originality of this Study: This study is distinctive in its demonstration of the effective use of I. tinctoria extraction waste as an organic fertilizer, aligning with zero-waste principles and contributing to improvements in plant growth and soil fertility. Furthermore, it investigates the synergistic effects of mycorrhizal associations on enhancing nutrient absorption and overall productivity of I. tinctoria , an aspect that has not been thoroughly explored in prior research.

The production of agricultural commodities is affected by the reduction of productive land, whichis due to the land conversion into residential and industrial areas. Maximizing the potential of dry land with biochar and organicfertilizerapplication can potentiallybecome the solution to overcome it. Biochar functions to retain water and hold nutrients, while organic fertilizer can enhance soil fertility. The research aims to analyze the effects of biochar and organic fertilizers application on soybean growth in agroforestry planting areas. This research was conducted at Menggoran Forest Resort, Playen, Gunungkidul, Yogyakarta, from March to June 2022. The experiment was designed in a factorial randomized complete block design (RCBD) with two factors. The First factor was types of biochar (without biochar, rice husk biochar, coconut shell biochar), and the second factor was types of organic fertilizer (without organic fertilizer, chicken manure, cow manure, and goat manure). The observed variables were leaf area index (LAI), specific leaf weight (SLW), leaf area ratio (LAR), specific leaf area (SLA), crop growth rate (CGR), net assimilation rate (NAR), and soil N-total percentage. The data were analyzed using analysis of variance (ANOVA), and if the treatment showed significant differences, Duncan’s Multiple Range Test (DMRT) at a 5% significance level was performed. The results showed no interaction between the type of biochar and the type of organic fertilizer. The application of biochar and organic fertilizers tested did not increase any of the observed growthparameters.The application of organic fertilizer independently has an effect on the percentage of soil N-total, and cow and goat manure application resulted in significantly higher final soil N-total percentages compared to without organic fertilizer treatment.

The use of biological fertilizers on maize is one way to increase crop productivity which refers to sustainable agriculture. This study aims to determine the effect of biological fertilizers on the growth and yield of hybrid maize. The research was conducted from May to September 2019 at the Jumantono Experimental Garden in Sukosari village, Jumantono, Karanganyar. The method used was a factorial Randomized Complete Block Design (RCBD) with one factor, namely the dose of biological fertilizer consisting of 4 levels, 0, 12, 20, and 28 L.ha-1), Liquid biological fertilizers used are biological fertilizers containing Azospirillum sp., Azotobacter sp., and Bacillus sp. The results showed that the 12 L.ha-1 dose of biofertilizer significantly affected plant height, stem diameter, and leaf area index compared to the control (0 L.ha-1). Biofertilizer was able to increase plant height, stem diameter, and leaf area index by 9.3, 13, and 19%, respectively. The optimum dose of biofertilizer on acid soils was 12 L.ha-1 with a seed yield of 3.5 tons.ha-1 or an increase of 23.02% compared to control. This study concludes that the dose of 12 L.ha-1 can be used as a recommendation to farmers for hybrid maize cultivation on acid land.
