The Philippine Agricultural Scientist
Cotton plays an important role in increasing productivity in the agricultural sector and related industries in the province of Golestan, Iran. However, the cultivation areas decreased considerably in the last couple of decades due to the high costs of production, water scarcity, and climate change. To encourage sustainable increase in production, crop simulation models are parameterized for each region using observed field data. In this study, the AquaCrop model was calibrated and validated for cotton under different field management scenarios using data from a 3-yr field experiment, which was conducted at the research farm of the National Cotton Research Institute, …

Variety Trial And Fertility Of Fescue Cultivars In Southeast Kansas, Dale Helwig, Bruno Pedreira, Junior Yasuoka
Kansas Agricultural Experiment Station Research Reports
In fall 2021, five varieties of fescue were planted at the K-State Research station outside of Columbus, Kansas. The varieties included two endophyte free (E-) varieties, two novel endophyte (NE) varieties, and one endophyte (E+) variety. The varieties were Atlas (E-), Cajun (E-), Bar Optima (NE), Estancia (NE), and K-31 (E+). Three rates of nitrogen were applied in the spring to each variety; 0, 50, and 100 units and each treatment was replicated three times. Due to the drought, measurements were not taken in 2022 but samples were obtained in 2023. The only stress the plots received was lack of …
Nitrogen And Sulfur Fertilization’S Effect On Soybean Quality And Yield In Kansas, Yuri A. B. Gross, Luiz Felipe A. Almeida, Ignacio Antonio Ciampitti
Nitrogen And Sulfur Fertilization’S Effect On Soybean Quality And Yield In Kansas, Yuri A. B. Gross, Luiz Felipe A. Almeida, Ignacio Antonio Ciampitti
Kansas Agricultural Experiment Station Research Reports
This study evaluates the effects of nitrogen (N) and sulfur (S) fertilization on soybean yield and quality. Over three years (2021-2023), nine site-year studies in Kansas tested five fertilization strategies, including Check (no fertilization), S (30.3 lbs S ac-1), N (26.8 lbs N ac-1), NS (26.8 lbs N ac-1 + 30.3 lbs S ac-1), and Full (30.3 lbs S ac-1 + 299.8 lbs N ac-1). Seed yield was recorded, and the seeds were analyzed for protein content. Weather data was summarized into four growth periods. There were no yield or …
