Abstract

Rice is one of the important plants being a staple food for almost the whole Indonesians. Upland (Gogo) rice can be increased by extensification using coastal sandy land. The upland cultivation techniques on the sandy land need an appropriate method to obtain high growth and production. This study aims to examine the effect of tillage on sandy land toward the three upland rice (Oryza sativa L.) varieties to rice growth and production. This study was conducted using a 3 x 3 split-plot experiment with a Randomized Block Design (RBD) consisting of 4 groups. The tillage methods as the main plot are J1: without tillage, J2: partially tillage, J3: fully tillage. The rice varieties as the subplots are P1: inpago, P2: inpago 10, P3: inpago 12. The observation parameters are plant height, number of tillers, the age of panicles appear, number of panicles, plant wet weight, plant dry weight, net assimilation rate, number of grains per panicle, grains production, the weight of 1000 seeds, harvest index, and the percentage of the filled grains. The result of the study shows that the tillage method has a real and significant effect (P<0, 05) on Upland rice growth and production. The inpago 8 variety without tillage was able to produce the highest dry weight and 1000 seeds. The highest grain production was in the partially tillage method. The inpago 10 variety in the partial tillage method was able to produce the highest number of grains per panicle, grains production, 1000 seeds weight and harvest index.  However, in the partial tillage method, inpago 12 variety was able to produce the highest grains per panicle, grains production, 1000 seeds weight and harvest index while without tillage method produced the highest dry weight and the highest filled grains percentage.

Abstract

The germination phase of sugarcane is a pivotal stage crucial for successful cultivation. Seeds derived from six to eight-month-old gardens, obtained from protrusions of sugarcane stems, are employed. These seeds exhibit characteristics of dormant buds, contributing to their suitability for germination. A single sugarcane stem typically harbors a minimum of 13 buds, and the selection of seeds with 2-8 eyes per spike is customary among farmers. However, excessive bud usage may lead to abnormal seed growth, underscoring the importance of careful selection. The study employs the rase cage test system, dividing the sugarcane stem into upper, middle, and bottom sections to determine the optimal bud quantity in each treatment. The research investigates the response of different parts of sugarcane bud chip stems to varying concentrations of coconut water growth regulator during germination. Utilizing a factorial randomized block design, the study comprises 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%). 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 exhibits the fastest and most efficient shoot emergence, with an average of 5.1 days, outperforming other treatments. These findings underscore the importance of careful selection and treatment in 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

Cucumber (Cucumis sativus L.) is one type of vegetable from the cucurbitaceae family that has been grown by farmers in Indonesia. The research was conducted for 4 months from September 23 to December 13, 2022 in one of the experimental fields owned by PT Aditya Sentana Agro. The purpose of this study was to determine whether the 2 candidate varieties CI-88 and CI-87 of kyuri cucumber tested would show significant differences in characters from 3 comparison varieties F1 MK 01, F1 MK 02, F1 MK 03 and to determine whether the results obtained from the 2 candidate varieties CI-88 and CI-87 of kyuri cucumber to be used as varieties and produced. This study consisted of 2 genotypes of hybrid variety candidates CI-88 and CI-87 and 3 comparison varieties namely F1 MK 01, F1 MK 02 and F1 MK 03 which were used as treatments. The three comparison varieties were used because they were in high demand in the market so that they had a high selling value and had a good response from farmers. Qualitative characteristics observed were stem shape, leaf shape, flower color, fruit shape, fruit skin color, fruit flesh color, and fruit taste test. The results of observations of qualitative character traits are presented in the form of tables and picture documentation. The results of quantitative characterization observations include stem diameter, fruit weight per plant, fruit weight per fruit, fruit diameter, fruit length, number of fruits per plant, leaf width, leaf length, age from flowering and age from harvest. The results of the two candidate varieties tested have the opportunity to be developed and registered as new varieties because the results obtained are comparable to the comparator varieties already on the market..

Abstract

Strawberries (Fragaria sp.) are a popular fruit and have high co mmercial value worldwide. Strawberry production continues to increase, but challenges related to temperature and environment affect fruit growth and quality. Temperature is a major factor in strawberry growth. Increased temperature can also affect fruit size, weight, and color, as well as sweetness. This study used a literature search method to analyze the impact of temperature and environment on strawberry growth. To overcome these challenges, the use of greenhouses is one of the appropriate techniques for climate engineering. Greenhouses create suitable temperature conditions and protect plants from adverse climatic conditions and can maintain optimal temperatures for strawberries. Nonetheless, it is necessary to consider the use of shading techniques in greenhouses. Relative humidity also plays an important role, and dehumidification techniques, such as dehumidification ventilation, are required to maintain optimal internal conditions.
