Abstract

Lettuce is a vegetable plant whose needs always increase every year according to population growth. Therefore, it is necessary to make efforts to increase the production of lettuce by increasing the number of seeds per planting hole using the DFT hydroponic system. This study aims to determine the effect of the number of seeds per planting hole on the growth and yield of lettuce plants and to determine the number of seeds per planting hole that produces the highest growth and yield of lettuce plants. Implementation This research was conducted from August to September 2021. Located in the Community Food Barn, the Department of Food Security and Fisheries, Banjar Regency. The method used in this study was a completely randomized design (CRD) with treatment S1 (control), S2 (2 seeds per planting hole), S3 (3 seeds per planting hole), and S4 (4 seeds per planting hole). The treatment was repeated 4 times to get 16 experimental unit Based on the results of the research, it can be seen that the number of seeds per planting hole has an effect on the growth and yield of lettuce. The best treatment was found in S4 which had the highest value at an average plant height of 36.25 cm, an increase in plant height at 28 DAP of 11.61 cm, an average number of leaves of 22.06 strands, and an average yield harvest of 153.75 grams. DFT hydroponic cultivation of lettuce resulted in optimal production of 4 seeds per planting hole. Useful research for the efficiency of lettuce production using hydroponics. In addition to production efficiency, it is necessary to consider plant competition to utilize existing resources for optimal growth

Abstract

Chili is one of the most valuable horticultural commodities, yet production is declining year after year. Fruit fly pests, which cause losses of 30-60%, are a stumbling block to growing chili production. Several types of aromatic vegetable extracts were used in this investigation, including clove leaves, babadotan, citronella leaves, and basil leaves, all of which have been found to contain methyl eugenol components. The goals of this study were to find the most efficient form of aromatic vegetable extract for usage as a fruit fly pest attractant and to see how different aromatic vegetable extracts affected the intensity of fruit fly pests.  The treatments were set up in a completely random order and were repeated three times. Planting chilies, creating aromatic vegetable extracts, making traps, deploying traps in the field, estimating the number of trapped fruit fly populations, and finally assessing the results were all part of this study. P1 = clove leaf extract, P2 = babadotan leaf extract, P3 = citronella leaf extract, and P4 = basil leaf extract are the therapies that will be provided. Bactrocera dorsalis was identified as the captured fruit fly species. The clove leaf extract treatment had the most fruit flies captured (35.67), while the babadotan leaf extract had the least (29.76), but none of the treatments were substantially different

Abstract

Water hyacinth is a type of plant that grows in freshwater environments. This plant is an ideal raw material to produce bokashi which increases the availability of soil nutrients. To maximize the function of the water hyacinth bokashi, a growth regulator is used to encourage plant upatake of soil nutrients. This study aimed to examine the single effect and interaction between water hyacinth bokashi (BHW) and plant growth regulators (PGR) on black rice. Data were analyzed with a factorial randomized block design. The first factor is WHB (B) 0 ha-1 and 2 t ha-1, while the second factor is PGR (Z) 0 ppm and 1.5 ppm. The results showed that the best effect of grain weight per hectare was treatment with WHB 2 t ha-1, PGR 1.5 ppm, and their interactions were 10.34 t ha-1; 11.09 t ha-1, and 12.16 t ha-1 harvested dry rice

Abstract

Indonesia is a mega-diversity country with numerous endemic plants distributed throughout its regions. An Indonesias’ island with the unique and the highest endemic plant species due to being located in the Wallace area is Sulawesi Island. Hopea celebica, an endemic species to Sulawesi Island, is currently categorized as endangered by IUCN. Here, we selected the ISSR primers suitable for the genetic study of H. celebica from Luwu and Konawe provenances and investigated their genetic diversity. Ten ISSR primers were employed in primer screening, and fifty H. celebicaindividuals were genetically analyzed for their genetic diversity. The selected ISSR primers for genetic diversity analysis were UBC 810, UBC 813, UBC 814, UBC 820, UBC 822, UBC 823, and UBC 827. The evaluated H. celebica individuals have high genetic diversity, and this information will be beneficial for designing H. celebica breeding and conservation strategies

Abstract

Integrated nutrient management is an alternative for the sustainable and cost-effective management of soil fertility by combined apply of organic with inorganic fertilizer resulting in rising soil fertility and productivity. This study aims (i) to determine the growth and yield respons of mungbean to different level of organic and inorganic fertilizer, and (ii) to measuring the effectiveness of organic fertilizer on mungbean production. The research was conducted at Pasar VI Kwala Mencirim Village, Sei Bingai District, Langkat Regency, North Sumatra in December 2020 to April 2021. This study used a Non-Factorial Randomize Complete Block design consisting of seven treatments and four replications, namely P0 (without fertilizer), P1 (100% dose of NPK fertilizer), P2 (75% dose of NPK fertilizer), P3 (50% dose of organic fertilizer + 75% NPK fertilizer) P4 (100% dose of organic fertilizer + 75% NPK fertilizer), P5 (150% dose of organic fertilizer + 75% NPK fertilizer), and P6 (1 dose of organic fertilizer + 100% NPK fertilizer). Plant height observations were carried out at 4, 6, and 8 weeks after planting and production observations were at harvest. Analysis of varian (ANOVA) was used to determined the effect of fertilizers treatment and followed by Duncan Multiple Range Test (DMRT) at 5% confidence interval for significant differences between treatment on plant growth and production. Organic fertilizer effectiveness was calculating using the Relative Agronomy Effectiveness (RAE). The results showed that organic fertilizer had a significant effect on mungbean growth and yield compared to controls. The highest mungbean production in P6 treatment of 1209 Kg/ha while the control treatment was 512 Kg/ha. Organic fertilizer was effective to increase mungbean production. The highest relative agronomic efficiency (RAE) was 438% in the treatment of organic fertilizer fertilizer at P6 of 100% dose of organic fertilizer +100% NPK fertilizer

Abstract

Ultisols are soil types that are poor in nutrients, one of which is element P, where this nutrient is needed by plants in large quantities. In Ultisols, P nutrients are bound by Al, so the availability of P nutrients for plants is low. Giving organic matter is one way to speed up the process of soil amelioration. Tofu waste is organic waste that contains nutrients and can be used as organic fertilizer that can help improve soil nutrients. Tofu dregs contain organic N, P, K, Ca, Mg, and C, which have the potential to increase soil fertility. This study aims to determine the effect of tofu pulp bokashi application on the dynamics of phosphate in Ultisols soil and to obtain the best dose of tofu pulp bokashi on the availability of phosphate in Ultisols soil. The method used in this study was a 1-factor Completely Randomized Design (CRD) with 6 (six) levels of treatment with 3 (three) replications in order to obtain 18 experimental units. Treatment P0 was without giving bokashi, P1 was P fertilizer 200 kg.ha-1, P2 was bokashi tofu dregs 12 t.ha-1, P3 was bokashi tofu dregs 24 t.ha-1, P4 was bokashi tofu dregs 12 t.ha-1 and fertilizer P 200 kg.ha-1, P5 namely bokashi tofu dregs 24 t.ha-1 + fertilizer P 200 kg.ha-1. The results of this study showed that the administration of tofu dregs bokashi had a significant effect and the best dose was obtained for increasing pH and available P by giving bokashi tofu dregs 24 t.ha-1 and P fertilizer 200 kg.ha-1. The best dose to reduce Al-dd is by giving bokashi tofu dregs 24 t.ha-1 and P fertilizer 200 kg.ha-1
