This study aims to determine the concentration of NaCl which can be used as maize resistance limit to salinity and to obtain varieties that are tolerant to salinity. This research was conducted in the form of an experiment with randomized design factorial using two factors in the group. As the first factor is the variety of Arjuna, Sukmaraga, Bhishma, Gumarang, Heroine Yellow, Pacakka, Anoman-1, and LAMURU. The second factor is the concentration of NaCl with 0 g L -1 , 3 g L -1 , 4 g L -1 , and 5 g L -1 . The results showed that the level of resistance of some maize varieties to salinity using NaCl produce varieties that have different resistance levels to high levels of salinity, there are varieties that can withstand the high NaCl concentration and some are only able to survive on a low NaCl concentration. The test results obtained sequentially showed varieties that are resistant to salinity is Pacakka. The concentration of 5 g L-1 NaCl can not be used as a concentration limit for the grouping of maize resistance to salinity.
This study aimed to determine the growth and production of katokkon chili plants (Capsicum chinense Jacq.) in the application of gibberellins and liquid organic fertilizer. This research was conducted at the Experimental Farm of the Faculty of Agriculture, Universitas Hasanuddin, Makassar from May to October 2017. The research was conducted in the form of a two-factors factorial experiment. The first factor was gibberellins consisted of four levels namely 0 ppm, 25 ppm, 50 ppm and 75 ppm, and the second factor was liquid organic fertilizer consisted of three levels of 25 ml L−1, 50 ml L−1 and 75 ml L−1 with three replications. Results of the study show that application of gibberellins on the local chili plant of katokkon interacted with liquid organic fertilizer improved the vegetative growth of the plant. Gibberellin also significantly affected the production parameters of the local chili plant. The fruit weight per plant and per hectare decreased with the increased of gibberellin dosages. No significant effect of the use of liquid organic fertilizer found, however, the treatment of 75 ml L−1 showed better results in several research parameters.
This study aims to determine the growth and production of rice in various planting systems and types of liquid organic fertilizer. The research was conducted in Rijang Panua Village, Kulo District, Sidenreng Rappang Regency from May to August 2016. The research was conducted based on a split plot design with main plot set was planting system consisted of three levels, namely: the tile planting system (20 cm × 20 cm), the legowo planting system 4:1 (40 cm × 20 cm × 20 cm), and 2:1 legowo planting system (40 cm × 20 cm × 20 cm). Subplot was type of liquid organic fertilizer made from three types of raw material, namely Gliricidia tree leaves, banana weevils, and Gliricidia leaves + banana weevil. The results show that there was a significant interaction effect between the two treatments on parameters of plant height, number of grains per panicle, production per plot and production per hectare. The combination of 2:1 legowo planting system and the liquid organic fertilizer made from Gliricidia leaves + banana weevil gave the highest yields on production per hectare (5.55 ton.ha−1). Highest number of productive tillers and an earlier flowering age were observed in the 2:1 legowo planting system (32.26 tillers and 60 days after sowing).
One of the obstacles faced in the expansion of the dragon fruit planting area is limited cutting materials to produce high quality seedlings. This study aimed to study the growth of dragon fruit (Hylocereus costaricensis L.) seedlings from two sources of cuttings at various concentrations of shallots. The research was conducted at the Teaching Farm of the Faculty of Agriculture, Universitas Hasanuddin from November 2018 to February 2019. The trial was set based on Split Plot Design with source of cutting materials as the main plots, consisted of two types of sources ie. apical primary branch and basal primary branch, while concentration of shallots solution as sub plot, consisted of five levels, namely 0, 200, 400, and 600 g.L−1 water, and Rooton-F 10 gL−1 water. The results show that the growth of the dragon fruit seedlings from two different sources of cuttings at various concentrations of shallots did not show significant differences. Sources of cuttings from the basal of the primary branch gave the best results on the number of shoots (2.40 shoots). Application of various concentration of shallot solution resulted in the highest percentage of life cuttings (100%) compared to control (75%). The concentration of shallot solution of 600 g.L−1 water showed the highest results in shoot length (28.33 cm), root length (31.09 cm) and root volume (66.67 mL). The use of Rooton-F as a positive control gave the highest results in root length (31.09 cm) and root volume (66.67 mL).
This study aims to study the adaptability of wheat mutant lines in the lowlands and determine the growth and production of the mutant lines. The research was conducted from September to December 2017 at Teaching Farm, Faculty of Agriculture, Hasanuddin University, Makassar, South Sulawesi Province. The study was carried out in the form of experiments arranged based on Randomized Block Design and further tested using orthogonal contrast. The treatments given were five M5 mutant genotypes and two convergent breeding genotypes. Three wheat varieties Dewata, Munal, and Selayar were used as comparisons. The results showed that the convergent breeding line (CB 145) showed good genetic traits on plant height parameters and the number of empty floret. Dewata, Munal, and Selayar varieties showed more average number of tillers (6.00 tillers) and 100 heavier grain weight (4.07 g) compared to the mutant genotypes. Dewata variety showed good genetic characteristics on panicle length parameter (6.50 cm) and grain weight per panicle (0.34 g). CB 169 genotype showed good genetic characteristics on the parameter number of grain per panicle which only produced the number of seeds per panicle (8.33 seeds).
