Response of Six Begonia Species to Fertilizer Concentration and Substrate pH

Growth and Photosynthetic Response of Pot-in-pot-grown Conifers to Substrate and Controlled-release Fertilizer

Container production of landscape conifers, including pot-in-pot (PIP) production, is increasing relative to field production in the northern United States. Because much of the research on PIP has been performed in the southern United States, this study focused on characterizing the growth and physiological response of PIP-grown conifers to fertilizer and substrate to improve production for gro...

Variation in the response of barley cultivars to nirrogen fertilizer

Collection and Concentration of Urine to Produce a Mineral Fertilizer

This study focuses on the development of a method which makes it possible to remove a maximum amount of water from urine whilst keeping nutrient losses as low as possible. With this goal in mind, three different urine drying systems, so-called as batch, circulation and continuous systems, were designed and assessed in Can Tho University. Their operations are based upon the principle of solar di...

Response of Marigold Flower Yield and Yield Components to Water Deficit Stress and Nitrogen Fertilizer

In order to study the effect of water deficit stress and different nitrogen levels on flower yield, yield components and water use efficiency of Calendula officinalis L., an experiment was conducted as split plot based on randomized complete block design with three replications, at research field of Islamic Azad University, Birjand branch in 2009. In this experiment, irrigation treatments (irri...

Response of Emmer and Durum Wheats to Different Levels of Nitrogen Fertilizer

Emmer tetraploid hulled wheats are considered as the ancestor of modern wheat and have considerable potential for durum wheat improvement, especially in terms of grain protein content. To investigate the response of emmer and durum wheats to different levels of nitrogen fertilizer, eight durum and four emmer genotypes were evaluated in the field during 2017 cropping season. The experiment was c...
