Abstract

Hydroponic technology is a solution to overcome the limitations of agricultural land with high production and quality. Macro and micro nutrients are elements that are useful for plant growth and development. Over-absorption of elements that contribute little to crop productivity and quality can be avoided, and fertilizer costs can be minimized by applying elements quantitatively to the nutrient solution supplied to plants. The purpose of this study was to determine the nutritional formula with macro and micro nutrients in red spinach (Amaranthus tricolor L.) with the desired plant size, so that fertilization management can be obtained. The research used several levels of nutrient concentration and circulation of water flow. At 25 hst when red spinach was harvested the nutrient concentration formula that showed the highest yield was 311 mg/l-1 nitrogen, 76 mg/l-1 phosphorus, 349 mg/l-1 potassium, 286 mg/l-1 calcium, 157 mg /l-1 magnesium, 248 mg/l-1 sulfur, 7 mg/l-1 iron, 2.9 mg/l-1 manganese, 0.6 mg/l-1 zinc, 0.6 mg/l-1 boron, 0.1 mg/l-1 copper, 0.06 mg/l-1 molybdenum. This calculation is a proper concentration to be used as a reference for sustainable hydroponic nutrient management. Keywords: nutrient concentration, red spinach, hydroponics, NFT system

Abstract

The germination phase is a crucial stage in the successful cultivation of sugarcane. Seeds obtained from six to eight-month-old gardens, extracted from sugarcane stems' protrusions, are used. These seeds have dormant bud characteristics, making them suitable for germination. Typically, a single sugarcane stem contains at least 13 buds, and farmers usually select seeds with 2-8 eyes per spike. However, excessive use of buds may result in abnormal seed growth, emphasizing the need for careful selection. The study utilizes the rase cage test system, dividing the sugarcane stem into upper, middle, and bottom sections to determine the optimal bud quantity in each treatment. It investigates the response of different parts of sugarcane bud chip stems to varying concentrations of coconut water growth regulator during germination. Employing a factorial randomized block design, the study includes two factors: Bud chip (BA: Upper Stem, BT: Middle Stem, BB: Bottom Stem) and coconut water growth regulator concentration (Z1: 25%, Z2: 50%, Z3: 75%, Z4: 100%). The positive control involves Agrogibb at a concentration of 120 ppm, with all treatments soaked for six hours. Conducted at the Indonesian Sugar Plantation Research Center on January 10, 2023, the study reveals that the BBZ1 treatment significantly affects the observed parameter of shoot emergence, with an average of 8.1 days. Conversely, the BAZ1 treatment shows the fastest and most efficient shoot emergence, with an average of 5.1 days, outperforming other treatments. These findings emphasize the significance of careful selection and treatment during the germination phase for optimal sugarcane productivity.

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

The ridge gourd plant (Luffa acutangula L.), native to India, thrives in Southeast Asian countries, including Indonesia, and holds significant value in traditional medicine. This study, conducted from September to December 2022 on PT Aditya Sentana Agro's experimental land, aimed to identify superior genotypes with high yield potential for ridge gourd production. Employing a Completely Randomized Group Design with one factor (genotype) and three replications, the research focused on qualitative (e.g., stem and leaf characteristics, flower and fruit attributes) and quantitative variables (e.g., leaf width, stem dimensions, flowering and harvest age, fruit dimensions, weight, yield, and storability). Notable findings include variations in fruit skin color as a qualitative trait. In terms of quantitative traits, certain variables such as leaf width, male flowering age, harvest age, fruit diameter, fruit length, and weight per fruit did not exhibit significant differences among genotypes. To enhance ridge gourd production, the study suggests the development of varieties with high yields and early maturation. This could contribute to the plant's adaptability in both highland and lowland environments. The comprehensive evaluation of qualitative and quantitative traits provides valuable insights for selecting the best candidate varieties to improve ridge gourd cultivation and productivity.

Abstract

This study examined the effect of growing media and the combination of PGR concentration and soaking time on root induction in Lipstick Aglaonema (Aglaonema crispum L.). The study aimed to evaluate the interaction between growing media and the combination of PGR concentration and soaking time on root induction in Lipstick Aglaonema, as well as to identify the optimal growing medium that meets export standards for this plant. The experimental design used was a Factorial Randomized Block Design (RBD), where factor 1 was the combination of PGR concentration and soaking time: K1 (water), K2 (Atonik 2 ml/l for 20 minutes), K3 (Rootone-F 200 mg/l for 1 hour), K4 (Prokar PGR 10 ml/l for 15 minutes), K5 (Prokar PGR 10 ml/l for 30 minutes), and K6 (Prokar PGR 10 ml/l for 45 minutes). The second factor was the growing media: M1 (a mix of manure, cocopeat, soil, rice husk, and charcoal), and M2 (a mix of cocopeat and rice husk charcoal). There was an interaction between the growing media and the PGR concentration and soaking time on leaf area and stem diameter parameters. The longer soaking treatments using Prokar PGR for 15 and 30 minutes were more effective for enhancing the growth of Lipstick Aglaonema cuttings in terms of the number of roots and root length. However, the growing media did not significantly affect all observed parameters.

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

     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.
