Abstract

The research was conducted at the Experimental Garden of Hasanuddin University (UNHAS) located in Baraya, Makassar, South Sulawesi from March to June 2022. This research was in the form of experiments conducted in soybean plant pots. The media used was soil obtained from post-nickel mining in Sorowako, East Luwu Regency, South Sulawesi. Research in the field is arranged according to a Randomized Block Design (RAK) with 3 replications. The treatment design used a 2-factor factorial design. The first factor is the type of Organic Material or Compost (K) consisting of 4 levels, namely; K0 (without organic matter), K1 (Kirinyuh compost), K2 (gamal compost) and K3 (rice husk compost) and the second factor is Urea (U) fertilization treatment consisting of 4 levels, namely; U0 (without Urea fertilizer), U1 (100 kg ha–1 Urea), U2 (200 kg ha–1 Urea), U3 (300 kg ha–1 Urea). The number of pots used was 4 units per treatment so there were 192 units of observation. The two factors tested resulted in 16 treatment combinations. The results showed that gamal compost (Gliricidia sepium) gave the best effect in increasing plant height, number of soybean leaves and weight of 100 soybean seeds. The results showed that urea dose of 100 kg ha–1 gave the best effect in increasing plant height and number of soybean leaves. The results showed that there was no interaction between the administration of the type of organic matter and the dose of urea

Abstract

Heritability is a measure that describes the magnitude of a genetic influence on a character rather than an environmental factor. The higher the heritability value of a character, the higher the genetic variability. The aim of the study was to know the interaction between the combination of growth regulators and chrysanthemum varieties that gave the best chrysanthemum growth in vitro and analyzed the heritability of various chrysanthemum characters. The research was carried out at the In vitro Laboratory of Agronomy Department, Faculty of Agriculture, Hasanuddin University, Makassar from May to September 2016. The study used a separate plot design in the group. The main plot was a combination of growth regulator consisting of 200 ml Coconut Water, 0.5 ppm BAP + Coconut Water 100 ml, BAP 1 ppm + Coconut Water 100 ml, 2,4-D 0.5 ppm + Coconut Water 200 ml, 2,4-D 0.5 ppm + BAP 0.5 ppm + Coconut Water 100 ml, 2,4-D 0.5 ppm + BAP 1 ppm + Coconut Water 100 ml. The subplots included 8 varieties of chrysanthemum (Fiji Pink, Marimar, Pasopati, Salzieta, Solida Pelangi, Limeron, Arosuka Pelangi, Yellow Tumohon). The basic media used was MS medium. The results showed that adding 200 ml young coconut to the culture media gave the best in-vitro chrysanthemum growth in terms of shoot and root formation, shoot count, root number, and shoot height in all chrysanthemum varieties; as well as all observed characters have high heritability and genetic variability

Abstract

Aluminum (Al 3+) is rhizotoxic ions in the soil (mineral) acid. Al activities increases with increasing soil acidity, below pH 5.5 the solubility of Al 3+ cations will increase. High level of soluble can cause interference with metabolic processes and plant physiology. Cumulatively, the physiology of metabolic disorders and initially looked at the root system. The tip of the root and lateral roots become thickened and hair and roots become lower, causing a decrease in root length and root tissue enlargement thus inhibiting the growth of roots, the absorption of nutrients and water, will further lower the growth, production and productivity of crops. Although Al disrupt metabolism and suppress the growth of the plant, until a certain threshold of adverse effects in Al still be tolerated, depending on the type of plant and the level of activity of Al. Tolerance of crops to Al can be expressed through two mechanisms, namely: external tolerance mechanism and internal tolerance mechanism. The main difference between the two mechanisms is in the area of detoxification Al whether in symplast (internal) or apoplast (exclusion). The ability of plants to be able to adapt to drought stress Al, depends on the ability of plants to produce organic acid in an amount sufficient for eliminating the toxic influence of stress Al. Root exudates of plants capable of producing such an organic acid that plays an important role in adaptation strategies. The high production of organic acids is associated with the formation of specific enzymes, as a response to stress Al. Allegedly the sensitive strain, the synthesis of organic acids is not adequate to chelate Al

Abstract

The purpose of this study was to determine the effect of biofertilizer application based on the types and spraying frequencies on the yield components of maize variety SINHAS 1. The research was conducted in Tarowang Village, Galesong Selatan District, Takalar Regency from August to November 2020. Three types of biofertilizer were used applied in five different frequencies of spraying. The study employed a split plot design with types of biofertilizer as the main plot and application frequencies as the sub plots. The research was repeated 3 times, resulted in a total of 45 experimental units. The maize variety used was SINHAS 1 and observations were made on the yield components of the ear height, wet weight of peeled cobs, ear length and diameter, percentage of seed yield, weight of 1000 seeds at 15% moisture content, and productivity. The results shows that the frequency of biofertilizer application had more dominant effect than the type of biofertilizer. The type of biofertilizer used has relatively the same role in the growth of the yield components of SINHAS 1 corn. Based on the results, it is recommended to apply the biofertilizer in four times in fertilizing the SINHAS 1 maize crop

Abstract

Galoba durian is one of the endemic floras from Maluku. Galoba durian is a species belonging to the Amomum genera Zingiberaceae family. It is also used as a medicinal plant for waist and kidney diseases. Based on the color of the fruit, galoba durian is divided into two nmely red galoba durian and green galoba durian. Distribution of this plant in Ambon can found in a few places such as highland and coastal area. Different locations influence phenotypic of plants, but may not show different genetic characteristic. Genetic diversity can detected by molecular markers. Genetic characterization from galoba durian using RAPD markers has not been done before. This study aimed to analyze genetic diversity from galoba durian using molecular markers RAPD. Samples of plants are used red galoba durian from Hatu and green galoba durian from Hatalae. The result of the first study, characterization of the morphology of the galoba durian, showed that both galoba have almost similar characteristics. Further DNA was tested by qualitative and quantitative. Result shows good qualitative and quantitative of DNA genomic. The second study was amplification by PCR-RAPD. DNA amplifications were performed using 3 primers out of 9 screened random primers. The primers selection was based on hight polymorphism. DNA amplification has 36 bands which were 100% polymorphic. The size of each bands from visualization of agarose was determined by linear regression. Number of band amplified was range from 120 to 1612 bp. Polymorphic band of RAPD showed the highest  genetic diversity. It can be concluded that the two plants of galoba durian are different species

Abstract

Planting material or seed is the most determinant factor for oil palm productivity alongside agro climatological and management considerations. A study was conducted to determine the different varieties of oil palm planted in smallholders’ plantations, the distribution channels for oil palm seeds and all the actors involved in the seed trade sector in Cameroon. This is a bid to secure the supply of only improved planting materials to smallholder farmers. 230 oil palm smallholder plantations were surveyed and individual palms were subjected to varietal determination. The Chi-Square Test (c2) for Fixed Ratio Hypothesis (= 0.05) was used to determine whether the observed ratio deviates significantly from the Mendelian hypothesized genetic segregation ratio. Up to 65% of smallholder farms were found to be planted with poor planting material distributed in the different Mendelian ratios; 100% Dura, 50% Tenera and 50% Dura (1:1), 25% Dura, 50% Tenera and 25% Pisifera (1:2:1). The source of this poor quality planting material for these farms was deduced to come from private nursery entrepreneurs and workers of industrial plantations such as the Cameroon Development Corporation (CDC), Cameroon Palm Oil Company (SOCAPALM), Common Initiative Groups (CIG’s) and Non-Governmental Organisations (NGO’s). Farmers supplied by government services especially the Ministry of Agriculture and Rural Development and some of its specialized development projects all received good quality material. Thus, this is the only means now available which can assure the distribution of seeds good quality seeds

Abstract

High rice consumption necessitates an improvement in rice quality. Rice quality issues can result from pest attacks, unhulled rice transportation, harvesting, and drying. An alternative is to use a drier to enhance the quality of rice. Therefore, research to evaluate the quality of rice dried in a dryer with various drying times is required. The Rice Milling Unit, Harapan Village Unit Cooperative (VUC), Tiroang Sub-District, Pinrang District, located at coordinates 3O48'41"S and 119O42'5E, was the site of this study. This study was set up using a Randomized Block Design (RBD), with the treatment of unhulled rice drying duration, namely drying according to farmers' customs (A0), drying for 10 hours (A1), and drying for 12 hours (A2) using a dryer at an average temperature of 65OC. The results showed that a good percentage of whole grains, broken grains, groats grains, whitewash grains, yellow grains, red grains, unhulled grains, and foreign grains were obtained by drying the grain using a dryer for 12 hours. The novelty of this research is the finding of the right unhulled rice drying time using a dryer
