Abstract

Shallots (Allium ascalonicum L.) are cultivated as a high economic value agricultural business. Cutting the tip of the seed bulb can stimulate, accelerate and synchronize plant growth. In hydroponic cultivation, the volume of planting media is an important component that needs to be considered. This research was conducted at the Greenhouse Hydroponic Farm Lamongan, Lamongan District, Lamongan Regency, East Java. Split plot design (RPT) or split plot design in a Completely Randomized Design (CRD) with the main plot (main plot) the volume of planting media (U) with 3 levels: 10cm (U1), 15cm (U2), 20cm (U3) and sub plots (sub plots) are the size of the cutting of the seed bulbs (P) with 4 levels: not cut (P0), cut 1/4 (P1), cut 1/3 (P2), cut 1/2 (P3). It was found that the treatment of the size of the cutting of the seed bulbs affected the vegetative and generative variables. Meanwhile, the treatment of planting media volume affects generative variables, especially on the number of harvested bulbs per box and the weight of harvested bulbs per box. The most optimal interaction between the combination of the size of cutting seed bulbs and the volume of planting media occurs at the size of cutting seed bulbs of 1/4 part and the volume of planting media of 10 cm, which is able to increase the weight of harvested bulbs per clump.

Abstract

This study aimed to determine the optimal harvest time and packaging type to preserve the quality of Inpari 32 rice seeds during storage. Conducted at the Food and Horticultural Plant Seed Supervision and Certification Unit in East Java from November 2023 to April 2024, the research used a factorial experiment in a completely randomized design (CRD) with three replications. Harvest age treatments were 110, 120, 130, and 140 days after seedling (DAS), while packaging types included plastic sacks, polyethylene (PE) sacks, polypropylene (PP) sacks, and aluminium foil. Data were analyzed using ANOVA and Duncan's Multiple Range Test (DMRT) at a 5% significance level. Results showed that harvesting at 120 DAS with PP sacks yielded the highest starch content, while 140 DAS with aluminium foil resulted in the lowest reducing sugar content. Optimal germination and growth speed were achieved at 130 DAS, which also minimized electrical conductivity. Harvesting at 140 DAS produced the highest 1000-grain weight. Aluminium foil packaging maintained the lowest moisture content and significantly improved germination and growth speed compared to other packaging types. These findings suggest that optimizing harvest age and packaging type can significantly improve seed viability and storage performance.

Abstract

Lettuce is a type of vegetable plant that is consumed by the wide community. Hydroponic lettuce cultivation has become an alternative as land area decreases as a result of land-use conversion. This research aims to determine lettuce growth which is influenced by the type of planting media and nutrient discharge. This study was conducted at the Greenhouse Emak Farm and Hidroponik Wadungasri, Waru District, Sidoarjo Regency, East Java, adopting a Split Plot Design with the main plot of nutrient solution discharge (L) consisting of 3 levels, namely L1 = 1.5 L/min; L2 = 2 L/min; L3 = 2.5 L/min. The subplot is the planting media (M) consisting of 4 types, namely M₁ = rockwool; M₂ = rice husk charcoal; M₃ = cocopeat; M₄ = fern. The observed variables comprised leaf number, leaf area, plant height, stem diameter, total plant biomass, stem and leaf biomass, root biomass, harvest index, and plant age. The results indicated that the combination of fern-based growing media and a nutrient solution flow rate of 1.5 L/min produced the most favorable outcomes for all measured parameters, with the exception of the harvest index. Nutrient flow rate of 1.5 L/min was recommended for hydroponic using fern growing media.

Abstract

Sunflower (Hellianthus annuus L.) has high economic value due to its great potential in industry. High market demand causes the need for intensification in sunflower cultivation to increase production and seed quality. This study aims to determine the right dosage and time of paclobutrazol application in suppressing growth and increasing the yield of sunflower plants. The research was conducted in Dohoagung Village, Balongpanggang District, Gresik Regency from May to September 2024. This research used a Factorial Completely Randomized Design (CRD) with 2 factors, namely dose and application time. The two treatments resulted in 12 combinations, each of which was repeated three times. The results of the analysis of variance were further tested with the 5% HSD test.  The results show that the combination of paclobutrazol dosage of 0.3 g/plant and application time of 4 WAP gives the best results on plant growth (plant height and stem diameter). The single treatment of paclobutrazol dosage of 0.2 g/plant gave the best results on flower diameter, number of seeds, total seed weight and 100 seed weight. A single treatment of paclobutrazol application time at 4 WAP produced the best plant growth and increased flower diameter.
