Abstract

Bird pepper (Capsicum frutescens L.) is one of the main commodities of horticulture in Indonesia. The process of assembling bird pepper was done by selected from the segregation population. This study aimed to obtain selected plant candidates in the F2 population by index selection on the character of the yield components on bird pepper. The results of this study showed that in population F2-285290 the correlation value showed a very significant significance for all characters on the yield component character while in the population F2-321290 only fruit thickness and fruit stalk length were not significantly correlated. The broad mean heritability value in the high category of the two populations were in fruit weight, fruit length, fruit diameter and fruit stalk length. The results of index selection in the population F2-285290 with a selection intensity 10 percent obtained by selected plants as many as 20 best plants, namely plants no 16, 30, 31, 36, 43, 50, 65, 80, 82, 102, 123, 134, 153, 190, 216, 244, 245, 263, 273 and 290 while in populations F2-321290 selected plants are no. 18, 21, 23, 30, 32, 37, 42, 154, 155, 162, 165, 167, 180, 185, 199, 220, 221, 230, 228 and 229

Abstract

Rubber plants (Hevea brasiliensis) will experience a decrease in production as plant age and the nutrient content in the soil decreases. This study aims to find out the chemical properties of soil on plantations of rubber crops that are converted into palm and coconut crops. The research was conducted from October 2023 to January 2024 at the palm coconut plantation of PTPN III Aek Nabara North Garden in Labuhanbatu district and analyzed in the Land Laboratory of the Faculty of Agriculture of the University of Northern Sumatra. The methods used are observation methods, field sampling, and analysis in the laboratory to obtain quantitative data. Observation parameters include soil pH, C-organic, Total Nitrogen, Available P, Cation Interchange Capacity, and Base Fulness. The results of the survey showed that the level of soil fertility at the site of the research was included in the low category. The main limiting factor that causes the low fertility of the soil is the low content of organic material in the soil. In order to improve the fertility status of the ground at the research site for further planting, it is necessary to make efforts such as irrigation and fertilization, as well as the addition of organic materials, to make the availability of nutrients for plants more affordable

Abstract

This study aims to determine how the interaction occurs between the best concentration of EMS with gibberellin in inducing aglaonema variegata and regeneration of aglaonema Red Majesty in vitro. The research was conducted at the Tissue Culture Laboratory of the Faculty of Agriculture, Hasanuddin University and took place from January to June 2022. The study used the method of Separate Plots Design in a Completely Randomized Design as the environmental design. The results showed that the best mutant genetic diversity and in vitro regeneration at 0.3 percent EMS concentration with 15 ppm gibberellin (variegata), and 45 ppm (chimera) and 0.6 percent EMS concentration with 0 ppm gibberellin (variegata) had different characters compared to the control treatment and other treatments

Abstract

The corn crop cannot be separated from the presence of weeds as crop disturbers. The presence of weeds often causes a decrease in yield and seed quality in corn crops. The yield reduction depends on the type of weed, density, duration of competition, and allelopathic compounds released by weeds. This study aimed to determine the age of the critical period of competition of hybrid varieties of corn plants against weeds, as well as corn grain production due to competition with weeds. The research was conducted in a group randomized design consisting of seven weed control treatments based on corn planting age and repeated three times. Observation parameters consisted of plant height, number of leaves, cob length, cob weight, and cob circumference. The observation results were analyzed followed by Least Significant Different (LSD) at 0.05 percent level. The test results showed that the critical period of competition of corn plants against weeds occurred at the age of 20-45 days after planting. The highest average corn cob weight occurred in the weed control treatment in the third week after planting which was 126.67 gr. There was a compatibility between corn plants and weeds in the form of competition for nutrients and growing space, which affects production

Abstract

The unavailability of high-yielding varieties can cause low production of tomatoes. Excellent variety construction in plant-breeding programs is possible as an effort to solve the tomato cultivation problem. This study aimed to evaluate the yield of several tomato strains from the cross-breeding product of Mawar × Chung. This study was conducted at the experimental garden, Faculty of Agriculture, Hassanuddin University from April to July 2023. From the results, a strain with high productivity level was obtained from the KM 10.10.6 (g6), which produced an average of 1432.64 g and was significantly different from both parent plants. This strain also had high heritability levels of plant height, dichotomic height, number of branches, flowering period, harvesting period, number of fruit bunches, number of fruits, fruit length, fruit diameter, fruit weight and productivity. Moreover, this strain had four characteristics that positively correlated to production, namely plant height, stem diameter, number of branches, and number of fruits

Abstract

Maize is one of the most important food crops after rice. This study aimed to obtain one or more doses of fertilizers that provide high growth and productivity, obtain one or more varieties of maize that have increased productivity, and obtain interactions between doses of fertilizers with maize varieties that deliver high growth and productivity. The research was conducted at the Experimental Farm (KP) of the Bajeng Cereal Crops Research Center, Bajeng District, Gowa Regency, South Sulawesi. At an altitude of 27.2 meters above sea level, with coordinates 5018'21.5 "N, 119028'38.6 "E and an average temperature of 28.50C. The research was conducted from September to December 2022. This study used a separate plot design, fertilizer dose as the main plot consisting of 3 fertilizer doses, namely N:P:K equals 160:120:80 kg N.ha-1, N:P:K equals 200:150:100 kg N.ha-1, and N:P:K equals 240:180:120 kg N.ha-1. The subplots were corn varieties: Sinhas 1, Jakarin, Nasa 29, JH 36, Bisi 18, ADV Joss and Pioner. The fertilizer dose with the highest productivity compared to the other five is N:P:K equals 240:180:120, with an average productivity of 6.66 t.ha-1. The variety that produces the highest productivity compared to the two types is ADV Joss, with an average productivity of 9.28 t.ha-1. The combination of N:P:K fertilization dose equals 160:120:80 with ADV Joss variety gave the highest productivity compared to the combination of fertilization dose and other types with an average productivity of 9.38 t.ha-1. The correlation between productivity and parameters such as plant height, number of leaves, cob weight, cob diameter, cob length, cob length, number of seed rows per cob, seed yield, 1000 seed weight, and NDVI showed a positive interaction.
