Published: October 2020

Abstract
Sweet potato is a food commodity that has high economic value and is an alternative staple food because of its energy and nutrition content. This study was in the form of parametric approach by assigning weights to each of the characteristics of both land and climate required for sweet potato plant growth. Climate and land suitability analysis was performed using the square root method. The results of climate suitability analysis showed that there were two periods of sweet potato plant growth, namely in November-March (S2) and March-July (S3) with a limiting factor in relative humidity (RH) and the length of the sun’s irradiation (n/N) which could not be improved. Land suitability analysis in the November-March growing period showed that there are two land suitability classes namely S3 (land units 1,2, 5 and 6) and N (land units 3 and 4). The limiting factors were soil depth, organic carbon and climate (humidity and length of sun exposure). Organic carbon is improvable by adding cover crops, soil depth with a high level of management, while climate such as relative humidity and irradiation are not manageable.

Abstract
A study aimed to evaluate the growth and production of several synthetic maize lines at low nitrogen level was conducted at the Indonesian Cereals Research Institute Experimental Farm in Bajeng District, Gowa Regency, South Sulawesi. The research was carried out from September to December 2018. The study also aimed to determine the nitrogen dose that could be used for selection of synthetic maize genotypes against low nitrogen doses. The study was conducted in the form of an experiment using a Split Plot Design. Five levels of Nitrogen fertilizer were used namely 0, 50, 100, 150, and 200 kg N per hectare. Various genotypes treatment were consisted of 4 synthetic maize genotypes namely Syn 5, Syn 6, Syn 7, Syn 8 and 2 comparative varieties namely Bisma and Lamuru. The results show a significant interaction between the treatment of nitrogen doses and the synthetic maize genotype on the morphological and physiological characters of the maize genotypes. Genotypes gave the best results at nitrogen doses of 100 kg N ha−1 was Syn8 (8.67 tons ha−1) and 50 kg N ha−1 (6.47 tons ha−1). Nitrogen doses of 50 kg N ha−1 and 100 kg N ha−1 can be used for the selection of maize tolerant to low nitrogen condition with productivity of 4.57 tons ha−1 and 8.67 tons ha−1, respectively. There is potential for the Syn8 genotype to be developed for low-nitrogen-tolerant maize varieties due to higher production compared to the comparative variety.

Abstract
A pot trial was conducted to study the effect of seed tuber physiological age on the leaf growth of two potato cultivars. The study was conducted in a controlled stress free environment in a glasshouse at University of Tasmania Horticultural Research Centre. Seed tubers of two cultivars (Atlantic and Russet Burbank) with different physiological ages were used. The trial was set up as a complete randomized block design with four replicates. Some leaf growth characters were observed including the leaf phenology and production. ANOVA on the observed parameters show a significant difference between the physiological ages of the seed tuber used in the leaf growth characters. Higher node or leaf appearance rate was observed in cv. Russet Burbank (39.5 °Cd per leaf) in the plants from older tubers compared to the younger seed tubers (51.2 °Cd per leaf). On the contrary, no significant differences were found for the leaf senescence rate. Seed tuber ages also affected the size of fully expanded leaves in cv. Russet Burbank but not in Atlantic. More branching was found in the plant established from physiologically older seed tubers.

Abstract
Indonesia has a tropical climate with high rainfall. The high rain will affect the state of hydrology until the peak discharge is a flood. Other factors that influence flooding are morphometry, topography, soil type, and land cover conditions. The Kelara watershed in South Sulawesi has been flooded. Then a flood effort in the disaster mitigation disaster watershed is needed in the form of land use planning. So, this study conducted a mapping of watershed morphometry analysis, flood vulnerability areas, and hydrological modeling to obtain debit data using the Geographic Information System method. Based on flood mapping, the land use planning for mitigation will be formulated based on flood vulnerability areas, actual land use, district space patterns, and land suitability. The results showed that the morphometry of the Kelara watershed was not identified as vulnerable to flooding, namely the watershed shape, river density, and river gradient. While the mapping of flood vulnerability areas resulting from overlapping parameters of land cover, slope, elevation, and type of soil, indicates that there are flood vulnerability areas in Kelara watershed. The flood vulnerability areas to float in flat to gentle areas (0-15%) with a height of 0-50 meters above sea level and land that have a low infiltration rate. The peak of January in a maximum discharge of 1.7268 m3 / second Kelara river. Land use planning with the forest area and development of agroforestry patterns. The reduced land use planning of the maximum discharge on the Kelara River by 0.05 m3 / sec. But land use planning has not been optimal in decreasing peak discharge. So, it needs faster effort, namely other technical activities such as dam construction and river normalization.
