Abstract

The current condition is a lot of the transfer of agricultural land functions into housing and industry. Utilization of marginal land is one of the important solutions to be done. One type of marginal soil is inceptisol, with limiting factors for low soil chemical fertility, especially the element P. The element P can become available for plants with the help of AMF. To reveal the performance of plant growth through the combination of three Jatropha cultivars with the best dose of arbuscular mycorrhizal fungi and cytokinin concentrations on plant photosynthesis results in two different locations. The experiment starts from January 2019 until June 2019 at an altitude of 0-50 meters above sea level (lowlands) and altitudes from 750 to 850 meters above sea level. The combined trial evaluated jatropha cultivar and the best arbuscular mycorrhizal fungi dose and repeated cytokinin concentrations three times. The results of the experimentshowed that there was a significant effect on each treatment and the interaction between the treatments with the best results was the concentration of cytokinin 400 mg L-1 for plant height growth variables, and the concentration of cytokinin 300 mg L-1 for the variable chlorophyll content of leaves, number of leaves, whereas cytokinin concentration 100 mg L-1 for stomatal conduction activity.

Abstract

Low-land rice (Oryza sativa L.) cultivation in saline soils face some constraints include nitrogen availability. Saline-resistant nitrogen fixing bacteria Azotobacter are expected to increase supply nitrogen in saline soils. The objectives of the study were to determine the effect of liquid inoculant concentration of two Azotobacter isolates on early vegetative growth of lowland rice grown in potted saline soil.  The greenhouse trial design was a randomized block design with seven treatments and four replications. The treatments were combination of isolates and Azotobacter liquid inoculant concentrations in single and mixed inoculation. The results showed that all plants experienced chlorosis and stunt due to high Electrical Conductivity. Inoculation of different isolates and concentrations did not influence the growth of lowland rice in soil with high EC at the end of experiment. Therefore, neither isolates nor concentration of Azotobacter could improve retarded-growth of lowland rice in saline soil.

Abstract

Garlic (Allium sativum L.) is one of the important commodities in the horticultural sub-sector which is one of the basic needs of the community that must be fulfilled. However, garlic production in Indonesia has not been able to meet the demands of society's needs. For this reason, an additional area of land for garlic development is aimed at the optimal suitability of environmental physical factors. The use of superior varieties is one of the technologies that play a role in increasing the productivity of garlic. This research was conducted in May - August 2020 in Tarusan and Muaro Aie Bayang Utara, Pesisir Selatan Regency, West Sumatra Province with a randomized block design using Lumbu Hijau, Lumbu Kuning and local varieties of Bukik Sileh Solok as treatment. The results showed that the varieties of Lumbu Kuning and Lumbu Hijau were able to adapt well in Muaro Aie with an altitude of 322 masl compared to Tarusan with an altitude of 4 masl. Both varieties gave a fairly good growth response and yield, although only half of the description of these varieties.
