Abstract

This study aims to determine the response of green bean cultivars to the application of biochar compost and the effect of biochar compost dosage on the growth and yield of green beans and the best dosage of biochar compost on the growth and yield of green beans, yellow beans and black beans. This study used a 4 × 3 factorial randomized block design that was repeated 3 times. The first factor is the dosage of biochar compost for cow manure which consists of 4 levels, namely control 0 t/ha, 10 t/ha, 15 t/ha, 20 t/ha the second factor is the type of green beans consisting of local green beans Timor Fore Belu, beans Black and yellow beans, which were repeated 3 times so that there were 36 treatment units. The parameters observed in this study are environmental parameters, growth parameters and yield parameters. The results showed that there was no interaction between the biochar compost dosage treatment with the type of bean on all observational parameters except for the observation parameters of plant height 21 days, root length 35 days, total root nodules 50 days, and number of pods per plant. Compost biochar affects the growth and yield of green beans. Types of green beans affect the growth and yield of plants. The best dose for the type of green bean speckle is 20 t/ha, yellow is 15 t/ha, black is 15 t/ha.

Abstract

In Indonesia, Capsicum frutescens L. is an important horticultural commodity, seen from the area of production and its value as well as its large enough role to meet domestic needs as an export commodity and the food industry. However, chili production in Indonesia is still very low. One of the efforts that can be done is to carry out plant breeding using colchicine. Colchicine is one of the reagents for mutations that cause polyploidy, ie organisms have three or more sets of polyploid chromosomes in their cells. The purpose of this study was to determine the effect of colchicine concentration on the phenotype performance of local Capsicum frutescens L. from the island of Timor and to get the concentration that gave the best results on the phenotype performance of local Capsicum frutescens L. from the island of Timor. The research design used was a completely randomized design, with 3 treatments and 6 replications. The treatments consisted of control: plants without colchicine, colchicine concentration of 5 ppm, and colchicine concentration of 10 ppm. The results showed that colchicine treatment showed a significant effect on the observed parameters of the stem diameter of 14 DAS and 28 DAS, and canopy area 14 DAS. Treatment 5 ppm colchicine concentration resulted in optimum growth and yield.

Abstract

This study aims to determine the response of plants through the application of natural phytohormones and to obtain the optimal concentration and frequency of the domestication of local cayenne pepper plants on the island of Timor. This study used a factorial Completely Randomized Design (CRD) consisting of two treatment factors. The first factor is the dose of organic ZPT (D) which consists of 3 levels, namely D0 control, D1 = 20 ml/water, D2 = 30 ml/water. The second factor is the application time of ZPT (B) which consists of three levels, namely B1 = 1 week, B2 = 2 weeks, B3 = 3 weeks. The results showed that there was no interaction between the time of application of phytohormones and the dose of phytohormones for all observed parameters. However, the best environmental parameters were given by a treatment dose of 90 ml/L with an application time of 2 weeks. The best growth parameters were given by treatment 90 ml/L with a time of application of 2 weeks on plant height parameters, treatment without the best phytohormone measurements on the parameters of stem diameter, weight of seeds per plant, weight of 100 seeds, fruit weight, number of fruits per plant, while the treatment without dose The phytohormone (control) produced higher yield characters than the 45 ml/L and 90 ml/L dose of phytohormone treatment. Treatment of the 45 ml/L dose is the best phytohormone measurement that provides the best fruit length per plant and fruit diameter for the cultivation of local cayenne pepper on the island of Timor.

Abstract

One strategy to increase the production and quality of shallots is to encourage the use of planting material through seeds known as true shallot seed (TSS). The purpose of this study is to increase the production of TSS seeds and improve the quality of TSS onion seed from Miomaffo Barat subdistrict. This research used the Randomized Block Design factorial. The first factor was an application of gibberellin (GA3), consisted of three treatments i.e without GA3 (control) applications, GA3 100 ppm applications and GA3 200 ppm applications. The second factor was vernalization treatment at 10 oC temperature with three treatments i.e without vernalization (control), vernalization for 2 weeks and vernalization for 4 weeks. The results showed that the highest number of capsule peracel was found in vernaliazation treatment 2 and 4 weeks that is 60.67 and 59.00. The highest number of sealed pest capsules was found in 2 and 4 weeks vernalization treatment, 42.75 and 54.83. The highest number of seeds was found in 4 weeks' vernalization treatment with the value is 108.14. The number of seed showed that no significantly difference on the all of treatment. The highest of a maximum growth potential was found in 4 weeks of vernalization treatment 70%, germination on 4 week vernalization treatment, 50%, vigor index on 4 week vernalization treatment, 46.00%.
