Abstract

Corn is one of the most important food commodities consumed by most people in various parts of the country. There is a real interaction between spacing varieties on the observed characters. There are one or more production chatacters that have a significant correlation with production. This research will be carried out at the Experimental Garden of the Bajeng Cereal Research Institute, Bajeng District, Gowa Regency, South Sulawesi, with a coordinate point of 5o18'21.5 "LS, 119o28'38.6" BT. The research was conducted from August to November 2020. This study used a separate plot experimental design. The main plot is a planting system legowo (S) which consists of 3 planting systems, namely the spacing of 75 x 20 cm = 66,667 pop / ha (J1), Legowo (50 + 100) x 20 cm = 66,667 population / ha (J2), and Legowo (50 + 100) x 18 cm = 74,074 population / ha (J3). Meanwhile, the subplots were maize varieties (V), namely NASA 29 (V1), Bisi 2 (V2), and Sinhas 1 (V3). From the research results, it can be concluded that the spacing has no effect on the character of the observation. the variety has a very significant effect on the observed character, except for rod diameter. As for the correlation, the observed characters that had an effect on production were ear length and weight of 1000 seeds

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

Productivity of superior genotypes often did not satisfyingly achieve its genetic yield potential. Interaction between genetics and environmental factors more likely to driven the final yield of the varieties. The concept of balanced fertilization is carried out by referring to the creation of a balance of macro-nutrients in the soil so that plants can produce optimally. The research was conducted in a form of experimental study at Tarowang village, Takalar Regency during growing season of 2021 from May to September 2021. A split plot design was used with fertilization package as the main plot and superior varieties as subplots. Three fertilization packages combined inorganic and organic fertilizer were used, namely fertilization package consisted of N: P: K with ratio of 225:100:75, fertilizer package that consisted of N: P: K ratio of 200:100:50 + KNO3 25 kg + Biotani 5cc L-1, and fertilizer package that consisted of N: P: K with a ratio of 200:100:50 + KNO3 25 kg + Ecofarming 5cc L-1. Six superior varieties used were Nasa 29, JH-37, Bisi 2, Bisi 18, SINHAS 1 and NK7328. Based on the level of both factors, 18 treatment combinations were obtained and repeated three times. Responses of maize varieties to fertilization packages, consisted of different combination and dosage of NPK fertilizers, KNO3 and organic fertilizers, were varied between varieties. The treatment of fertilization package of N: P: K = 225:100:75 with Bisi 2 variety gave the highest maize productivity, namely 12.39ton ha-1

Abstract

This research was conducted at the Hasanuddin University experimental farm, Moncongloe District, Maros Regency, South Sulawesi with two main objectives: (1) to determine the effect of acidic dry soil stress on genetic diversity and heritability values ​​of agronomic traits of corn plants and (2) to characterize candidate hybrids tolerant to acidic dry soil stress based on the production response of corn genotypes .Method: this study used 88 genotypes with a randomized block design adopted as an experimental design. The parameters in this study were: soil chemical properties, observation of plant characteristics, and analysis of stress tolerance index. Based on the results of this study, it can be concluded that: (1) dry acidic soil stress has an effect on the phenotype and low to moderate values ​​on the heritability of plants with the characters of 10 cob weight, cob length, and productivity having relatively higher values ​​than other characters. (2) Genotypes G62 and G86 occupy the intersection between high yields under optimum conditions (Yp), high yields on acid soils (Ys), and high STI values. Both genotypes are capable of maintaining high yields, namely 8.8–9.0 t ha⁻¹ at optimum conditions and 7.5 t ha⁻1 on acid soils. These characteristics reflect the ideal profile in breeding corn tolerant to acid soils.
