Abstract

The study conducted at the Integrated Laboratory of the Faculty of Agriculture and Animal Husbandry, University of Muhammadiyah Malang, aimed to formulate granule and liquid biofertilizers for corn cultivation on dry land in Indonesia, covering 144.47 million hectares. Corn is a crucial agricultural commodity in the country, aligning with the Sustainable Food Self-Sufficiency Policy program. Fertilizers, especially biological ones with plant growth-promoting rhizobacteria (PGPR), play a pivotal role in enhancing both the quality and quantity of corn production. The research utilized a Nested Split Plot Design, considering varying levels of drought stress (100%, 70%, and 40% of field capacity) and bacterial density (control, 10^9, 10^8, and 10^7). Results indicated no significant interaction between granular and liquid fertilizer densities across different field capacities. While the PGPR consortium in both fertilizer types showed limited effectiveness in boosting maize growth and yield, the highest average performance was observed at a density of 10^7. Additionally, certain stress levels did not contribute to increased maize growth and yield, except for the 100% field capacity treatment. It was noted that extreme temperatures, reaching up to 54°C in the plastic house, might have hindered the expected interaction. Plant growth tends to decrease drastically below 15°C or above 40°C, as these temperatures activate physical and chemical processes in plants. The study underscores the importance of considering environmental factors in optimizing biofertilizer effectiveness for sustainable corn cultivation on Indonesian dry land.

Abstract

The study conducted in Cikajang District, Garut Regency, from February 20 to June 15, 2023, aimed to assess the impact of different compositions of organic mulch, derived from water hyacinth and banana stems, combined with a blend of chicken and cow manure on lettuce growth and yield. Employing ANOVA analysis at a 5% significance level, with a DMRT follow-up test, the research involved seven treatments and two controls. The treatments included organic mulch without manure mixture (M1), and organic mulch with 5% (M2), 10% (M3), 15% (M4), 20% (M5), 25% (M6), and 30% (M7) cow and chicken manure. Positive control was Black Silver Plastic Mulch, and negative control was without mulch. The study revealed significant effects of organic mulch treatments on plant height, leaf count, and crop diameter during the initial vegetative growth stage. Specifically, treatment M5, comprising organic mulch from water hyacinth with a 20% mixture of cow and chicken manure, demonstrated a notable increase in net head weight per plot at harvest. This suggests the potential of this particular mulch composition for enhancing lettuce yield. The findings emphasize the practical application of organic mulch, particularly M5, as a beneficial strategy in lettuce cultivation, promoting growth and ultimately increasing harvest yield.

Abstract

In Indonesia, pineapple is one of the horticultural commodities that has the potential to be developed. It is seen that the amount of demand for fresh pineapple from abroad is quite high. Intensification of pineapple land is still lacking where the number of pineapple seedlings planted has only reached 2,500 from ideally 10,000 stems per hectare. Alternative to overcome this problem is by propagating plants in vitro through callus induction which later is thought to potentially have quality and quantity seeds as expected. This study uses a combination of ZPT 2,4-D and cytokines which are expected to grow callus with good quality and relatively faster time.This study uses Factorial Randomized Block Design (RBD). By using the first factor namely 2,4-D concentration and the second factor cytokines (BAP and TDZ). The data can be analyzed for variance and a real honest test (BNJ) level of 5%. Based on the results of the study, it was found that the combination of giving concentrations to 2,4-D and cytokines was not significant for each parameter. The interaction between 2,4-D growth regulators and cytokinins has no significant effect on the induction of pineapple varieties of Smoooth cayenne. The treatment of 2,4-D 0 mg/L - 5 mg/L growth regulators has no significant effect on callus induction in vitro on the Smoooth cayenne varieties. The treatment of cytokinin (Thidiazuron 0.001 mg/L - 0.1 mg/L and BAP 0 mg/L - 4 mg/L) had no significant effect on in vitro callus induction on the Smoooth cayenne varieties.

Abstract

Potatoes (Solanum tuberosum L.) are carbohydrate-rich crops. Low potato productivity in Indonesia stems from farmers' inadequate access to quality seed potatoes. One solution to this issue is enhancing quality seed potato production, achievable through aeroponic systems. Lighting, whether incandescent or LED, can optimize potato mini tuber propagation in aeroponic systems. Research on lighting's effects on potato growth remains incomplete. This study aims to investigate how lighting color and duration affect mini tuber production of Solanum tuberosum L. PPT4 Zebra using aeroponic systems. Conducted in Jurangkuali, Bumiaji sub-district, Batu, the study employed a split plot design. The main plot consisted of lighting colors (WC): light yellow (WK), white (WP), and purple (WU). Subplots were lighting duration (LP) at 3 hours (LP 3) and 5 hours (LP 5), each replicated four times. Each replication comprised 8 samples, with 18 potato plant cuttings per population. Variables included plant height, stem diameter, leaf count, chlorophyll level, root length, tuber count, tuber diameter, budding seed count, and tuber weight. Data were analyzed using F-tests followed by BNJ tests at a 5% significance level. Results indicated no interaction between lighting color and duration. Purple lighting yielded the highest tuber count and weight, while 3-hour lighting duration yielded superior plant height, stem diameter, leaf count, and root length.

Abstract

     Mustard green (Brassica juncea L.) is a leafy vegetable with a subtropical climate, but this plant can adapt well to tropical climates that it suitable to be planted and grow in Indonesia. The formulation of problem in this study is to lessen the use of chemistry fertilizer in fertilization on plants, especially mustard green (Brassica juncea L.). This study aims to review the growth response of mustard green (Brassica juncea L.) because of the dosage of cow compost and mycorrhiza fertilizer dosages. This study used a randomized block design (RBD) arranged in a split plot with 2 factors. The first factor as main block of cow compost dosage consists of three levels, they are 2,5 tons/ha, 5 tons/ha, and 10 tons/ha. The second factor is offspring block, a mycorrhiza dosage consisting of three levels: 1 tablet/plant, 2 tablets/plant, and 3 tablet/plant, each repeated 3 times. Observed variables are plant height, the number of leaves, leaf wide, fresh weight and dried weight of the plant, fresh and dried weight, fresh and dried ratio of root weight, and dried crown weight. The result of this study shows that there is no interaction between giving cow compost and mycorrhiza dosage toward mustard green height, fresh weight and dried weight, fresh and dried ratio of root weight and dried crown weight, but separately dosing cow manure 2.5 ton/ha can increase broad leaf mustard plants at 2 weeks after planting and dosage, as well as mycorrhiza 1 tablet/plants and 2 tablets/plant, has been able to increase leaf area from age 2 weeks after planting.
