Vetiver is widespread in saline areas. Only a few studies have reported that they are sufficiently tolerant of salt. The primary mechanism of salt tolerance in vetiver is still not known with certainty. This study aims to determine salinity's effect on early growth of vetiver (Vetiveria zizanioides L.) seedlings. This research was conducted in a greenhouse, Faculty of Agriculture, Universitas Sumatera Utara, Medan. This study used a non-factorial randomized block design (RBD), namely the salinity stress (S) which consisted of 3 levels: EC salinity levels of 0 (distilled water), 4 dsm-1 and 8 dsm-1. The salinity stress treatment showed a significant effect of reducing the growth parameters of plant height, leaf area, chlorophyll a and chlorophyll b. Salinity stress treatment gave significantly better effect in conditions without salinity stress.

Chrysanthemum sp is a plant that has the potential to be developed in Indonesia, apart from being an ornamental flower, it can also be used as a herbal medicine. One of the efforts to develop chrysanthemum can be done in vitro by using organic growth regulators such as shallot extract and indole acetic acid (IAA). The research aims to identify the effect of shallot extract and IAA on the growth of Chrysanthemum sp. The research was conducted at UPT Central Horticulture Seed Center, Medan Johor, in December 2019 - January 2020. The research used a factorial Completely Randomized Design (CRD) with 2 factors, namely the first factor was shallot extract which consisted of 4 levels, namely 0, 35, 70, and 105 g/L water. The second factor was IAA which consisted of 4 levels, namely 0.6, 0.9, 1.2, and 1.5 mg/L water. The results showed that the administration of shallot extract had no significant effect on the growth of chrysanthemum, but the administration of IAA had a significant effect on the number of leaves and plant height with the best concentration at 0.6 mg/L water. The interaction of the two treatments also had no significant effect on the growth of chrysanthemum.

Wheat is the largest cereal food in the world's staple food supply. The expansion of the wheat crop needs to be done through extensification efforts in the lowlands to increase domestic production. The main obstacles faced in the lowlands are the high air temperature and the intensity of sunlight. The research objective was to provide adaptive wheat mutant in the lowlands, especially in North Sumatra. The seeds of 3 varieties of wheat: Dewata, Basribey and G-21 were treated with gamma irradiation with a dose 100, 200, 300, 400, 500, and 600 Gy. Each treatment was repeated three times. The highest percentage of germination and vigor index due to the combination of treatment of wheat varieties with gamma rays was the combination of Dewata and 200 Gy which was significantly different from Basribey and G-21. Gamma irradiation treatment of 100 Gy on the three mutant wheat varieties showed differences in plant height, namely the G-21 variety, followed by Dewata and Basribey. The number of productive tillers showed significant variation between the gamma ray treatments for each mutant wheat genotype and the most productive tillers were at a gamma ray dose of 100 Gy for all wheat genotypes. The 100 Gy gamma ray treatment caused the number of seeds of the Dewata variety to be much higher than that of Basribey and G-21. The mutants obtained with the desired characters are the basic materials in assembling new superior varieties of wheat that are adaptive in the lowlands.

The demand for butternut squash which continues to increase every year makes farmers try to increase their production, one of which is by applying biological and organic fertilizers. This study aims to determine the response of growth and production of butternut squash to the application of mycorrhiza and quail manure. This study used a randomized block design with 2 factors and 3 replications. The first factor was the application of mycorrhiza which consisted of 3 levels, namely: 0, 2.5, and 5 g/plant, while the second factor was quail manure which consisted of 4 levels, namely: 0, 1, 2 and 3 kg/plot. The results showed that the application of mycorrhizae had a significant effect on fruit length and fruit weight. The application of quail manure had a significant effect on increasing fruit weight. The interaction of mycorrhizae and quail manure did not significantly affect all observed parameters. Although it had no significant effect, the application of mycorrhiza and quail fertilizer was proven to increase the growth and production of butternut squash compared to the control (without the application of mycorrhiza and quail manure). The combination of mycorrhizal 2.5 g/plant and quail manure 1 kg/plot could increase butternut squash production.
