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.

Abstract

Glutinous rice corn crops in Java show low productivity despite their potential. Agricultural land issues in Indonesia, such as soil fertility and excessive use of inorganic fertilizers, persist. Tithonia diversifolia plants are utilized for composting to address these concerns. Additionally, corn root microorganisms act as biological fertilizer, enhancing plant growth. This study aims to investigate the interaction between Tithonia compost dosage and corn root Rhizobacteria on glutinous corn growth and yield. Conducted in two locations—laboratory for Rhizobacteria isolates and field for composting and planting—the research employed a Divided Plot Design with 36 treatment combinations. Observations included plant height, stem diameter, leaf area, cob count, cob diameter, cob weight, and cob length. Results indicate interaction effects between Rhizobacteria and compost dosage on leaf area growth at 28 days post-planting. Additionally, there's an impact on stem blight intensity at 42 days post-planting. Rhizobacteria dosage didn't significantly affect plant growth or cob yield parameters. However, paitan compost dosage influenced plant height, stem diameter, and cob count, with the best response seen at 14 tons/ha dosage.

Abstract

The Oncidium sphacelatum orchid, commonly propagated vegetatively through pseudobulb separation, presents opportunities for further research into propagation methods and organic fertilizer application. This study, conducted in Batu City, aimed to explore the interaction between vermiwash concentration and shoot number on aeroponically cultivated Orchid sphacelatum Lind cuttings, as well as individual treatment effects. Employing a factorial RKLT design with shoot number (one or two) and vermiwash concentration (100, 200, or 300 ml/L) as factors, the study evaluated plant height, leaf count, stem length, shoot length, root count, and root length as variables. Data analysis involved ANOVA and BNJ tests. Results revealed that cuttings with two shoots and a 200 ml/L vermiwash concentration promoted optimal leaf growth. The number of shoots influenced shoot length, with two shoots demonstrating superior growth compared to single shoot cuttings. Interestingly, vermiwash concentration did not significantly impact shoot growth parameters, indicating that its effects may be limited in this context. This study sheds light on the potential benefits of using vermiwash in orchid cultivation, particularly in enhancing leaf growth when combined with multiple shoot cuttings. However, further investigation is needed to understand the nuanced effects of vermiwash on other growth aspects and its interaction with different propagation methods.Overall, the findings contribute to the optimization of orchid propagation techniques, providing valuable insights for orchid growers seeking to enhance plant growth and productivity sustainably. Further research could delve deeper into the mechanisms underlying the observed effects and explore additional variables to refine cultivation practices for Oncidium sphacelatum orchids.

Abstract

Pakcoy is a viable horticultural plant. High consumer demand, but the national pakcoy production is still low. This study aimed to examine the effect of various compost doses and PGPR doses on the growth and yield of pakcoy plants. This study used a 5x4 factorial RAL with 3 replications. The first factor is compost dosage (K) consisting of K0 = 0 kgN/ha compost, K1 = 138 kgN/ha compost, K2 = 69 kgN/ha compost, and K3 = 138 kgN/ha compost, K4 = 207 kgN/ha compost. The second factor is the PGPR dose (P) consisting of P0 = 0 ml/l water, P1 = 5 ml/l water, P2 = 10 ml/l water, and P3 = 15 ml/l water. The results showed that offering compost as much as 207 kgN/ha increased the growth and yield of pakcoy plants compared to giving 138 kgN/ha of inorganic fertilizer. The increase in the PGPR dose that was applied 2 times at planting and 14 days after planting (DAT) of 200 ml did not significantly increase the growth and yield of pakcoy plants.

Abstract

This study aims to obtain information on changes in the character of individual M2 generation mutant rice, similarities between individuals of the M2 generation mutant and its comparison, and correlation between variables. This research was conducted by observing the vegetative, generative, and potential yields of each individual rice mutant and its comparison. The data obtained were tested by cluster analysis and correlation analysis. The observations showed that almost all the characters of the M2 generation mutant individuals changed except for the qualitative vegetative characters. Cluster analysis based on quantitative vegetative character showed 1 different mutant individual (0% similarity), and 1 other individual with 38.83% similarity compared to other and non-mutant mutants, and commercial varieties. Based on quantitative and production generative characters, there are 2 distinct groups that differ from each other (0% similarity). The similarity range of each distinct group is 21.17-43.56%. The strong to very strong and very significant correlation that occurs in vegetative and generative characters with production is found between the number of tillers and panicles, total grain weight and dry grain weight of 98.7% each; 60.9% and 58.3%; the number of leaves is thus also between the number of panicles, total grain weight and dry grain weight respectively 91.3%; 53.3% and 53.4%; panicles with total grain weight and dry grain weight were 60.1% and 57.6%, respectively.

Abstract

Banana (Musa acuminata Colla) is a tropical fruit with great economic potential and export prospects. According to the Directorate General of Horticulture, Ministry of Agriculture, banana production from 2009 to 2014 fluctuated due to attacks by Plant Destruction Organisms (PDO), particularly Sigatoka disease caused by the fungus Mycosphaerella musciola. This study investigated biological agents like Trichoderma sp. and Gliocladium sp., along with liquid organic fertilizers, to control the disease without synthetic fungicides.The research, conducted at the University of Muhammadiyah Malang, used a split-plot design with two factors: biological pesticides (Tricogreen, Natural Glio, Trico-G) and liquid organic fertilizers (rabbit urine POC, shrimp shell MOL, banana hump MOL). The experiment had nine treatment combinations with three plant samples each. Results showed that biological pesticides significantly reduced Sigatoka disease intensity, with the J3P3 treatment (Trico-G and Banana Hump MOL) achieving the lowest infection rate of 29.55%, reducing disease intensity by 70.45%. Liquid organic fertilizers also improved plant growth, increasing leaf number and leaf area. This indicates that biological agents and organic fertilizers effectively manage Sigatoka disease and promote healthy banana plant growth.
