Abstract

The Effect of Lateral Branch Trimming Against Results and Quality of LongBean Seeds (Vigna sinensis L.) This study aims to determine the effect of the number of leaves that are left on the lateral branch roasting on the results of young pods of long bean plants. Thistudy uses a randomized block design (RBD). Treatment of the number of leaves lefton lateral branch pruning includes: total lateral pruning, leaving 2 leaves, leaving 4eaves, leaving 6 leaves and leaving 8 leaves on lateral branch pruning. This researchwas repeated 5 times, so as many as 25 experimental units were obtained. Variablesobserved included: main stem length, total number of leaves per plant, total leaf areaper plant, fresh weight and oven dry weight of plant parts above ground, number ofharvest pods per plant, fresh pod weight per plant, weight of oven dried pods perplant and the weight of fresh pods per hectare. The results showed that more leaveswere left on the lateral branch pruning causing the number of leaves, leaf area,weight of the plant part above the ground, and oven dry weight of the plant part onhe ground to increase. Total lateral pruning pruning treatment resulted in the numberof crop harvest pods, fresh pod weight, and oven pod dry weight with the highestaverage value. The total lateral pruning treatment resulted in the highest per hectarefresh pod weight of 25.59 tons.

Abstract

Effect of Seed Storage with Drum and Silo on the Shelf Life of 0, 1, and 2 Years on the Seed Quality of Corn (Zea mays L.) This study aims to determine the effect of seed storage with drum and silo on the shelf life of 0, 1, and 2 years on the seed quality of corn (Zea mays L) varieties sele. This study uses a completely randomized design (CRD) consisting of 6 treatments and 5 replications. The treatment is sixth with a storage drum storage period of 0, 1, and 2 years (DT0, DT1.DT2) and storage silo storage period of 0, 1, and 2 years (ST0, ST1, ST2). The observed variables include moisture content, germination, germination synchrony, seedling dry weight, and the growing strength. The results showed that the seed moisture content decreased with the longer shelf life of both the drum and silo storage. Likewise, other variables, such as germination, simultaneity of germination, seedling dry weight and strength grew. All of these variables are impaired by the longer storage of both the drum and the silo. Storage for one year either in drums or silos are still able to maintain the quality of seed corn above the standard, with over 80% germination.

Abstract

The Influence of Processing Time Delay To Rice (Oryza Sativa L.) Seed Quality of Membramo Variety This research was performed with the purpose to obtain tolerance of processing time delay after appropriate crop so it doesn’t affect the physical and physiological quality of rice (Oryza Sativa L.) seed.This experiment used the Complete Random Design (RAL) by using 8 treatments and 3 repetitions. Therefore, there are 24 experiment units. Research result data were tabulated and analyzed mode investigation according to design that was used, and if the treatment has significant influence then it is proceeded with Duncan’s multiple distance test (5%).Observation was carried out to water content variable during the crop (%), water content during the processing (%), water content during the test (%), the viability test/power of germination (%) and electrical conduction power test (? mhos cm-2 g1).Research results shows that the longer processing time delay the more increase clear water content, the lowest water content at the direct harvest processing and the highest at processing time delay at the seventh day. So thus the longer processing time delay the viability processing will decrease. The processing time delay until 2 days after the crop the rice seed viability is more than 80% (above quality standard, ISTA), the next delay the seed viability is already under standard. The electrical conduction power more increase by the longer seed processing time delay.

Abstract

The Effects of Processing Delays on Storage Ability of Soybean Seed (Glycine max L. Merril) Soybeans are the third important food crop in Indonesia after rice and maize. Proper handling or seed processing will affect the quality of the seeds obtained. Generally soybean seed can be stored for 3-4 months with the correct handling process. Delays in seed processing affect the appearance of seed quality both physical and physiological. Weather factors and facility limitations are the reasons for delaying seed processing after harvest. Soybean seed storage is important because soybean seeds are likely to be stored before the seeds are planted. This study aims to determine the effect of delayed processing that can be tolerated to store ability of soybean seeds. The experimental desain used was Completely Randomized Design (RAL) by a single factor with a processing delay which is consisting of five treatments and five repetitions. The observed variables were moisture content (%), germination (%), vigor saving test (%), growthability test (%), and electrical conductivity test (?mhos cm-1 g1).The results showed that delays of processing time after harvest in soybean seeds can effect the shelf life. The longer the processing time was delayed, the lower the storage ability of the seed. Seeds without delay in processing time can maintain seed viability for eight weeks of storage with the lowest electrical conductivity of 2,47 ? mhos cm-1 g1. Processing one day delays and two day delay after harvest can be tolerated because the seeds produced have a germination greater than 80% and still meet the standard of seed quality.

Abstract

Effect of Harvest Time on the Save of Long Bean Seeds (Vigna sinensis L.). Supervised Long bean plants have indeterminate growth type, ie vegetative growth is still active even though it has entered the generative growth phase. The indeterminate growth type causes the pods to form cook not at the same time. When harvesting long bean pods for quality seed production, it needs to be studied. The seeds before planting must undergo a process of storing both short and long term storage, so the seeds saving power that produced from the time of harvesting different pods also needs to be studied. This study used a completely randomized design (CRD) with three treatments when harvesting pods for seeds, namely physiological pre-cooking, harvesting at physiological ripe, and harvest after physiological cooking. The treatment was repeated nine times. The results showed that the treatment of harvest time had an effect on the shelf life of the beans. Harvest time when physiologically cooked has the longest shelf life compared to harvest time after or before physiological cooking. Seed quality when harvested physiologically during storage obtained the highest compared with the quality of seed yields before and after physiological cooking.

Abstract

ABSTRACT Effectiveness of Technique Extraction Test and Dry Heat Treatment to Seed Health of Chili Pepper (Capsicum frutescens L.). Chili (Capsicum frutescens L.) is one of the horticultural crops of the Solanaceae family that has a high economic value. Seed healty problems is one of the chili pepperproduction constraints. Chili seeds used by farmers mostly contaminated by seed-borne diseases such as viruses. This study aims to determine the effectiveness of seed extraction techniques and Dry Heat Treatment (DHT) in producing healthy red pepper seeds in a seed source trials of healthy plants and diseased plants. The design used in this research is completely randomized design (CRD) with 2 factors. The first factor was the extraction technique which consisted of three levels ie extraction technique using 2% HCl, extraction techniques using quicklime and extraction techniques using water. The second factor was DHT with 2 levels ie DHT and without DHT (NDHT). The results of this research showed that DHT treatment was effective in producing healthy chili pepper seedlings with healtinese 100%, while seed extraction techniques has not been effective to produce healthy red pepper seeds with a percentage of less than 90%. Interaction between extraction techniques and DHT on trial seed originating from sick plants showed real influence. Keywords: chili pepper, extraction techniques, Dry Heat Treatment, healthy seed
