Abstract

Conditions for good seed storage are part of a series of seed production and storage methods that affect the storability and quality of seeds. The use of desiccants can increase the viability and vigor of seeds in storage. This study aims to determine the right type of desiccant for soybean seed storage at various storage times. The research was carried out from February to July 2024 in Rancaekek Kencana Village, Bandung Regency with an altitude of about 700 meters above sea level. The study used a factorial completely randomized design (CRD) with four replications. The first factor is the type of desiccant consisting of three kinds, namely sawdust, activated carbon and silica gel. The second factor is storage time consisting of four levels, namely 4,8,12, and 16 weeks. The results showed that there was an interaction between the type of desiccant and storage time on water content and seed weight after storage. The germination capacity of soybean seeds showed no influence on various types of desiccants (sawdust, activated carbon and silica gel), namely between 87.25% - 94.75%, while the storage time of 8 weeks did not show any difference with the storage time of 4 weeks, which was 92.12%

Abstract

Good environmental conditions and balanced fertilizer are factors that influence the soybean production process to obtain high crop yields. It is hoped that the use of rice straw mulch coupled with regulating the potassium dosage can create a good environment and the availability of sufficient and balanced nutrients for the growth of the Dering-1 cultivar soybean plants so that yields can increase. This research aims to determine the effect of the type of straw mulch and the dose of KCl fertilizer to increase the yield of the Dering-1 cultivar soybean. The research was carried out from August to November 2024 in Rancaekek Kencana Village, Bandung Regency with an altitude of around 700 meters above sea level. From August-October it is still dry, but at the end of October 2024 there will be rain although the intensity is still moderate. The research used a split plot design with three replications. The first factor is the dose of straw mulch consisting of three levels, namely without mulch, 2 tons/ha of rice straw and 4 tons/ha of rice straw. The second factor is the dose of KCl fertilizer consisting of four levels, namely 50 kg/ha KCl, 100 kg/ha KCl, 150 kg/ha KCl and 200 kg/ha KCl. Observations were made on the components of soybean yield and yield. The research results showed that there was an interaction between the dose of rice straw and the dose of KCl fertilizer on the number of pods per plant, seed weight per plant, harvest index and soybean yield per hectare, except for the weight of 100 grains per plant. The best treatment was a treatment dose of 4 tons/ha of rice straw and 150 kg/ha of KCl fertilizer, with a yield of 2.18 tons per hectare of dry beans with a water content of 14 percent.

Abstract

Job's tears is a crop that has a big nutritional value so it needs to be developed, one of the obstacles in Job's tears cultivation is that the seeds have a thick skin that inhibits the germination process. To overcome this, namely by treating different soaking temperatures. This study aims to determine the response of germination and growth of Job's tears plants using several soaking temperatures, this was carried out at the Rancaekek Village Garden, Bandung Regency from June 2025 to October 2025 using a Randomized Block Design (RAK) namely soaking seeds at different temperatures, namely s0 (without soaking), s1 (ordinary water), s2 (temperature 30°C), s3 (temperature 40°C) and s4 (temperature 50°C) with each treatment repeated 5 times. The parameters observed were germination power, growth rate and maximum growth potential while the vegetative growth parameters included crop height, ILD and crop crease weight. The results of the study showed that germination power (66.4%), growth rate (0.98%/day) and maximum growth potential (39.67%) showed that treatment s2 gave an average value that tended to be higher compared to s0, s1, s3, and s4. Treatment s1 tended to have a better effect on observations of plant height 10 WAP (40.75 cm), crop height 12 WAP (70.45 cm), crop height 14 WAP (85.58 cm), plant height 16 WAP (94.27 cm), ILD (4.29) number of leaves (55.1), and dry weight per plant (512 g). With the right seed soaking treatment, germination can be accelerated and the growth of job's tears can be increased
