Abstract

The growth of weeds in immature cocoa plants is highly susceptible to competition for water, nutrients, and light, which can disrupt the growth of cocoa plants. Efforts to manage cocoa cultivation include weed control using the chemical herbicide paraquat dichloride, a non-selective contact herbicide. This study aimed to determine the effective dosage of paraquat dichloride for controlling weeds in immature cocoa plants, changes in weed composition, and phytotoxicity on immature cocoa plants following the application of paraquat dichloride. The study was conducted in Talang Sepuh Village, Talang Padang Sub-district, Tanggamus Regency, from March–May 2024. The research employed a Randomized Complete Block Design (RCBD) with six treatments and four replications. Treatments included paraquat dichloride at doses of 414 g/ha, 552 g/ha, 690 g/ha, 828 g/ha, mechanical weeding, and a control group (no weed control). Data variance homogeneity was tested using Bartlett's test, and data additivity was evaluated with Tukey's test. If the assumptions were met, the mean difference was analyzed using the Least Significant Difference (LSD) test at a 5% significance level. The results indicated that paraquat dichloride at doses of 414–828 g/ha effectively controlled total weeds, broadleaf weeds, and dominant weeds (Eleusine indica, Praxelis clematidea, and Synedrella nodiflora). Meanwhile, doses of 552–828 g/ha were effective in controlling grass weeds and dominant weeds (Ottochloa nodosa and Asystasia gangetica). The application of paraquat dichloride did not alter weed composition and did not cause phytotoxic effects on immature cocoa plants..Keywords : Herbicide, Paraquat dichloride, Weed, Immature cocoa.

Abstract

Optimal rice production is very important to meet national food needs amid a decline in harvest area and production yields. This study aims to analyze the influence of rice planting methods and genotype on the growth and yield of rice plants (Oryza sativa L.). The research was conducted on the Lampung State Polytechnic Experimental Land using a factorial Group Random Design (RAK) with two factors: the planting method (legowo row 2:1, planting distance 25x25 cm, and transplanter 2:1) and rice genotype (PTP 01, Inpari 24, Jeliteng, and Pandan Wangi) each method was repeated 3 times. The results of the study show that the interaction of planting methods and rice genotype has a significant effect on the growth and yield of rice plants. The combination of the 2:1 transplanter planting method and the Inpari 24 genotype gave the best results in terms of plant height (101.33 cm), number of saplings (29.33), number of productive saplings (25.00), and yield per hectare (12.48 tons/ha). The 2:1 transplanter planting method and the Inpari 24 genotype can be recommended as the best combination in increasing rice productivity.

Abstract

Groundnut (Arachis hypogaea L) is the most important commodity after soybean which has a strategic role as a national food source as a source of protein and vegetable oil. The use of inorganic fertilizers must be balanced with organic fertilizers that can help improve soil properties damaged by the use of inorganic fertilizers. The goal of this study was to ascertain how NPK dosages and palm oil liquid waste interacted to influence groundnut plant development and yield. The Randomized Group Design (RAK) is the design employed in this study. The first factor is palm oil liquid waste with a dose of L1 = 100, L2 = 200, L3 = 300 ml/plant. While the second factor is NPK with a dose of P0 = 0% (without NPK fertilizer), P1 = 25% (1 gram/plant, P2 = 50% (2 grams/plant), P3 = 100% (4 grams/plant). The parameters observed were plant height, number of leaves, flowering age, number of flowers, number of filled pods, number of empty pods, weight of filled pods, weight of empty pods, wet weight of stover, dry weight of stover, weight of 100 seeds. The best treatment is the combination of 300 ml/plant of palm liquid waste and 50% (2 grams/plant) NPK (L3P3). The best treatment is 50% NPK (2 grams/plant) (P2).

The negative impact for the community is liquid waste, But can utilized for agricultural purpose such as by using liquid waste fertilizer from palm oil mills. Sweet Corn is one of the commodities favored by the people of Indonesia because it tastes good and sweet, and contains many vitamins. However, the productivity of Sweet Corn in Bangka Belitung Islands is decreasing. This study aims to produce optimal Sweet Corn growth, by using from palm oil mills. This study used a split plot Randomized Block Design (RBD) with 3 replications. The main plot is sweet corn variety (V) consist of, V1= Super sweet variety, V2= Bonanza variety, V3= Paragon variety, and the subplot is the interval of application of palm liquid waste (P) consist of, P0= Control, P1= Interval once every 10 days, P2= Interval once every 20 days, P3= Interval once every 30 days. The results of statistical analysis showed that different varieties of sweet corn gave a significant effect on harvest age, cob diameter, cob weight with clobber, cob weight without clobber and yield per plot. Giving different intervals gives a significant effect on stem diameter and cob diameter. Bonanza variety is the best variety in sweet corn growth and production. Once every 10 days is the best interval for sweet corn growth and production. The interaction of paragon variety and interval of 10 days give the best result for the parameter of age of female flowering in sweet corn.   Key words: Interval pemberian, Pupuk organik, Limbah cair kelapa sawit, Jagung manis

Abstract

Rapid population growth and increasing demand for high-quality food drive the need for innovation in the agricultural sector. The main challenge faced is how to enhance production efficiency and the quality of agricultural yields sustainably. Pak choi, one of the fast-growing crops in Indonesia, requires special attention through various innovations to support its optimal growth. One of the key factors in pak choi growth is fertilization. However, the continuous use of synthetic fertilizers can damage soil fertility. As a sustainable alternative, Liquid Organic Fertilizer (LOF) has been developed from recycled green waste, specifically Leucaena leaves and pineapple peels. This study aims to evaluate the effects of LOF application derived from these organic waste materials on pak choi growth. This research was conducted in Sugih Waras Village, Belitang Mulya District, East OKU Regency. The research method used was a Completely Randomized Design (CRD) with 5 treatments and 3 replications. Data were analyzed using ANOVA and further tested with HSD at a 5% significance level. The results showed that the application of LOF had the best effect in the treatment was 45 ml LOF/polybag, with plant height reaching 21 cm, 23 leaves, root length of 15 cm, fresh plant weight of 116 grams, and dry plant weight of 12.1 grams.

Abstract

One of the techniques that can be applied to overcome seed decline is the invigoration technique using organic materials as priming, namely with young coconut water, bean sprout extract, and aloe vera extract. This study aims to determine the effect of the use of young coconut water, bean sprout extract and aloe vera extract on the viability and vigor of expired cayenne pepper seeds. This study was conducted at the Seed Laboratory of the Agrotechnology Department, Bangka Belitung University. This study used a Completely Randomized Design (CRD) treatment. The treatment given was in the form of organic materials used for priming (Z) with 4 levels of treatment, namely (z0) control, (z1) young coconut water with a concentration of 15%, (z2) bean sprout extract with a concentration of 80%, and (z3) aloe vera extract with a concentration of 50%. Soaking expired cayenne pepper seeds is done for 1 hour. The results of this study indicate that expired cayenne pepper seeds soaked in young coconut water with a concentration of 15% (z1) can increase the parameters of maximum growth potential, seed germination rate, vigor index, plumule length, and dry weight of normal seed sprouts which are better than the control although not significant. The treatment of soaking expired cayenne pepper seeds with organic materials had no significant effect, thought to be due to inaccuracy in the soaking dosage, soaking duration, and abscisic acid content in one of the materials used.

Abstract

Yield of green onion has been declining annually in West Kalimantan where land for cultivating green onion is alluvial soil. This study aims to determine the optimal dosage of a combination of areca husk biochar and NPK fertilizer on the growth and yield of green onion plants in alluvial soil. The research was conducted in Sungai Kakap District, Kubu Raya Regency, West Kalimantan Province, from September to November 2024. A non-factorial Randomized Block Design (RBD) comprised six treatments and four replications: b1 = biochar 2 tons.ha⁻¹ + NPK fertilizer 90% (270 kg.ha⁻¹), b2 = biochar 4 tons.ha⁻¹ + NPK fertilizer 80% (240 kg.ha⁻¹), b3 = biochar 6 tons.ha⁻¹ + NPK fertilizer 70% (210 kg.ha⁻¹), b4 = biochar 8 tons.ha⁻¹ + NPK fertilizer 60% (180 kg.ha⁻¹), b5 = biochar 10 tons.ha⁻¹ + NPK fertilizer 50% (150 kg.ha⁻¹), and b6 = biochar 12 tons.ha⁻¹ + NPK fertilizer 40% (120 kg.ha⁻¹). The observed variables included plant height, number of leaves, number of tillers, fresh weight, root volume, and dry weight. Data obtained from observations were analyzed using Analysis of Variance (ANOVA). If significant differences were found, a DMRT test at a 5% significance level was conducted to determine differences among treatments after obtaining the coefficient of variation (KK). The results showed that the treatment of biochar 10 tons.ha⁻¹ + NPK fertilizer 50% (150 kg.ha⁻¹) was the best dosage, significantly affecting plant height, number of leaves, number of tillers, fresh weight, root volume, and dry weight. Further research is recommended using different doses of areca husk biochar and NPK fertilizer, as well as incorporating additional factors, to evaluate their effects on the growth and yield of green onion plants in different soil types.

Abstract

The problem faced by hydroponic farmers in cultivating chili peppers is the lack of an optimal AB Mix nutrient formula that can be synthesized independently using chemical fertilizers readily available in agricultural supply store. This study aims to evaluate the effects of AB Mix nutrient formulation and variety on yield of curly chili peppers (Capsicum annuum L.) in hydroponic system. The experimental design was a Randomized Block Design (RBD) in 2-factor split-plot arrangement with three replications. The main plots consisted of four nutrient formulations. The subplots consisted of plant varieties, which included the Lado Juara F1 variety, the Joker genotype, and Lolay genotype. The result of the study showed that increasin of the concentration of the AB Mix nutrient formulation from N1 to N2 enhanced the number of fruits and the fruit weight per plant, both in the Lado Juara, Joker, and Lolay varieties. However, further increases the concentration of the AB Mix nutrienr formulation from N2 to N3 and N4 decreased the number of fruits and the fruit weight per plant in any of varieties. The use of the Lado Juara variety resulted in higher numbers of fruits and fruit weight per plant compared to the Joker and Lolay genotypes across all AB Mix nutrient formulations with a drip irrigation hydroponic system. Key words: Chili, formulation, hydroponic, nutrition, variety
