This study aimed to determine the effects of different types of fertilizers (organic and inorganic fertilizers) on plant growth, yield, and yield components of potatoes grown in the high-altitude plateau of eastern Türkiye in 2017 and 2019. In the experiment, single or combined doses of nitrogen (N; as ammonium sulfate) and phosphorus (P; as triple super phosphate) as inorganic fertilizers and leonardite (L) and vermicompost (V) fertilizers as organic fertilizers were used. In both years, different fertilizer treatments significantly affected plant growth, yield, and yield components. Tuber yield per hill (941.0 g), marketable tuber yield (32.71 t ha−1), total tuber yield (37.84 t ha−1), specific gravity (1. 077 g cm−3), chip productivity (35.9%), starch (13.03%) and protein (11.0%) ratios increased when N fertilizer was used in combination with vermicompost or leonardite. N fertilizer combined with V or L fertilizer increased tuber yield under harsh continental climates, short growth periods, and high altitudes.

It is known that salinity stress, one of the abiotic stress factors, significantly limits the germination, growth, development, and crop yield of plants. Therefore, this study was conducted to evaluate the effects of salinity (control, 50, 100 ve 150 mM) on seed germination and the effect of salicylic acid (control, 0.25, 0.50, 0.75 ve 1.00 mM) on seed germination to improve salt tolerance in cannabis seeds. The physiological characteristics of the plant, such as germination percentage, germination duration, germination index, radicle length, plumule length, wet radicle weight, dry radicle weight, wet plumule weight, and dry plumule weight, were analyzed. Depending on the salinity application dose, it was observed that there was a significant decrease in the germination parameters of cannabis seeds compared to the control. It was observed that salicylic acid treatments under salinity stress positively affected all the characters examined and reduced germination arrest due to increasing concentration levels. Although it is recommended to prepare seeds with 0.5 mM salicylic acid pre-application dose against salt stress of the cannabis plant,it is essential to expand the studies on its transfer to practice. As a result, salicylic acid will provide positive results that can be transferred to practice by increasing the resistance of cannabis plants against salinity, especially in agricultural soils with salt problems, as it will be more sensitive to pests and diseases.
