Abstract

Tomato production can’t fulfill the consumption needs of tomatoes. One way to fulfill this need is to expand the land by planting tomatoes in the lowlands. However, the limited number of cultivars suitable for planting in the lowlands is an obstacle. Assembling new superior cultivars of tomato plants that have good adaptations in the lowlands is one solution that can be done. The aim of this research was to produce a new tomato strain with superior characters. The research design was using a Completely Randomized Block Design, as a treatment consisting of eight new strains of F6 generation tomato plants, each experimental unit was repeated three times. The variables observed were maximum plant height, number of primary branches per plant, number of fruit bunches per plant, number of fruit per bunch, number of fruit per plant, age of plant beginning to flower, age of fruit starting to form until physiological maturity, fruit diameter, the weight of each fruit, fruit yield per plant, fruit yield per hectare. The data were analyzed for variance, if there was a significant difference between treatments; further tests were carried out with the BNT test at an alpha of 0.05. The results showed that each strain had various quantitative characters. The LA, LA1, and LH strains had a higher potential yield per hectare compared to the other lines. The heritability values in most of the observed quantitative variables have moderate to high values. This shows that the character is more controlled by genetic traits. Keywords: quantitative character, strain, tomato

Abstract

One of the plants favored by all levels of society is cucumber because the fruit is consumed in fresh form, besides that it is also an ingredient in cosmetics, medicines and can be used as industrial raw materials. The type of research land is sandy soil which has problems, namely poor structure, low water absorption and storage capacity. The aim of this study was to examine the effect of interaction between chicken manure and bokashi Kayambang on the growth and yield of cucumber plants on sandy soil. The study was arranged in a factorial manner, using a Randomized Block Design with 2 treatment factors, 3 levels and 3 repetitions. The research stages started from land preparation, nursery, planting, maintenance, fertilization, maintenance and harvesting. Based on the results of the study, it can be concluded that the plants that were given single treatment with bokashi Kayambang had a very significant effect on plant height at 21 and 28 DAP, number of leaves at 14 DAP, fruit length and number of fruit. While the combination treatment of chicken manure with bokashi Kayambang did not occur in all the observed variables. Cucumber fruit production per hectare using chicken manure treatment 2 t ha-1 and bokashi Kayambang 15 t ha-1 resulted in a weight of 2,911, 6 kg -1

Abstract

Peanut production both in Java and outside Java tends to fluctuate. Nuts have a high economic value and are one of the sources of protein in the diet of the Indonesian population. This study aims to determine the application of NPK fertilizer to peanut crop production. The study was conducted in Pangkalan Panji Village, Banyuasin III, in March-June 2021. This study was compiled using a one-factor Randomized Block Design (RAK) with four replications. The factors used consist of six levels, namely N0, N1, N2, N3, N4 and N5. The results showed that the application of NPK fertilizer had no significant effect on plant height and weight of peanut pods, while the parameters of number of pods, number of branches, weight of wet pods and weight of 100 grains showed a significant effect on NPK treatment of 300 kg/ha (50g/plot).

Abstract

At the selection stage in breeding with gamma irradiation mutation induction, seeds from the previous generation are needed to be planted in the field to obtain the next generation of mutants. The seeds before planting have undergone a storage period, during the storage period if the temperature, humidity, and storage conditions are not right it will affect the viability and vigor of the seeds which can reduce the germination of seeds in the field Tests to determine seed vigor can be done by conducting a conductivity test (DHL). The purpose of this study was to determine the conductivity value of each genotype of the third generation mutant and the percentage of germination of black soybean seeds during the storage period. This study used a non-factorial completely randomized design (CRD) with 10 mutant genotypes and 1 control (without irradiation), and each treatment was replicated four times. Observation variables were electrical conductivity/conductivity, germination rate, growth speed, growth synchronously, vigor index, and maximum growth potential. Based on the conductivity/DHL test, genotypes with high Conductivity/DHL values ​​have a low percentage of germination, but the percentage of germination is still above 80% during the storage period, so it is expected that they will still have high germination ability in the field. Keywords: electrical conductivity, black soybean, and conductivity.
