Abstract

Seed priming by soaking in KNO3 has been used to enhance seed performance and crop establishment in tomatoes. However, seeds that are immersed in a solution for a long time may be deprived of oxygen during critical phases of imbibition. Aeration during priming is a solution to solve this problem. Thus, this study aims to determine the effect of aeration and KNO3 in seed priming on the germination of tomato seeds. The seeds used in this study were tomato seeds var. Palupi. This study used seven treatments i.e. non-primed, KNO3 moistened paper, KNO3 soaking, KNO3 aeration, water moistened paper, water soaking, and water aeration. The study was arranged in a completely randomized design (CRD). All data were statistically analyzed using one-way ANOVA and followed by means analysis using Fisher’s LSD (Least Significant Difference) test at P<0.05. The result showed that all priming treatments gave a better performance in FGP (Final Germination Percentage), MGT (Mean Germination Time), and GRI (Germination Rate Index) compared to the non-primed. The best treatments, however, were observed in the aeration method in either KNO3 or water in all parameters observed. KNO3 gave a slightly better performance than water in all parameters, although there was no statistical difference between the two treatments.

Abstract

Organic household waste accounts for a large portion of Indonesia's waste management problems, especially in the Jember Regency. To overcome this, innovations such as the composting bin are viable for home-scale application. However, this innovation is not widely known by the people. The purpose of this extension activity is to introduce the composting bin to the people of the Antirogo village, Jember district. The counseling method was in the form of a demonstration of handmade aerobic compost. This activity was well received by the community where several households have succeeded in assembling their compost bins.

Abstract

The breeding of new high-yielding varieties is one of the solutions to the low productivity of soybeans in Indonesia. Superior genotypes of ‘GHJ-4 (A)’ and ‘GHJ-5 ’ were obtained in the previous study with an average weight of 13 g/100 seeds and a potential yield of 3 tons/ha. The attempt to increase the weight and size of the seeds of ‘GHJ-4’ and ‘GHJ-5’ was continued using the backcrossing method with ‘Ryoko  (>35 g/100 seeds) as a parent donor. F1 plants were obtained with an average weight of 15 g/100 seeds. This study aimed to determine the performance of the F2 generation of backcross in terms of the number of filled pods, the weight of 100 seeds, yield per plant (g), yield per plot (kg), and potential yield per hectare (tons/ha), as well as the heritability value of the genotypes. In this particular study, the F2 seeds from F1 plants were then planted and observed. This study used a non-factorial randomized block design (RBD) with 11 soybean genotypes, each consisting of 3 replications. The results showed that the F2 generations (GHJ-4XRyoko, RyokoXGHJ -5, and GHJ-4XGHJ-5) are considered as prospective new high-yielding varieties with a potential yield of ≥ 3.5 tons/ha, which have successfully restored the trait of ‘Ryoko’ and surpassed the performance of ‘GHJ-4’ and ‘GHJ-5’ as their parents in all parameters. The heritability value of the genotypes tested belongs to the high category, on the parameters of the number of filled pods (96.937 %), yield per plant (98.102 %), the weight of 100 seeds (99.132%), yield per plot (92.605 %) and potential yield per hectare (92.257 %).  For the parameters observed, the back cross yields of harvest age were 72-74 HST, the weight of 100 grains was 17-18 grams and the yield per hectare was around 4 tons/ha. The heritability value shows that the observed traits are inherited from parents on average more than 90% and the selection that will be used is pedigree selection.

Abstract

In Indonesia, the production of baby corn is generally derived from composite varieties because not many varieties have been exclusively bred for baby corn purposes. This study aimed to determine the quantitative and qualitative traits of five local maize varieties to obtain potential parent materials for baby-corn-purposed lines. The research was conducted at the Experimental Field of State Polytechnic Jember using a non-factorial randomized block design with five local maize varieties (‘Kretek Madura’, ‘Bisma’, ‘Provit A1’, ‘Srikandi Kuning’, and ‘Sukmaraga’). The data obtained were analyzed with ANOVA and followed by the Fisher’s Least Significant Difference Test at a 5% error level. The results indicated that all five varieties tested met the standards of Codex for baby corn in terms of diameter, length, and qualitative traits.  In terms of plant height, female flowering, and number of ears, V1 ‘Madura Kretek’ was observed to have the most potential as it had the shortest plant height (173.60 cm), the fastest female flowering (43.64 days), and harvest age (47.67 days), as well as the highest number of ears (2.55). However, this variety showed a lower baby corn weight, which might affect the total yield. It is suggested that the next quest of parent material for the baby-corn-purposed line can be also focused on the weight of the baby corn.
