Soil residual N is a potential factor threatening the environment, but it also an fertilizer resource. Few studies have evaluated fate of soil under agronomic practice. The objective this study was to investigate distribution and its possible influencing factors with different irrigation regimes. Under three situations created by previous season using 15N labeled urea, we employed lettuce as pl...

In many real-life problems, decision-making is reckoned as a powerful tool to manipulate the data involving imprecise and vague information. To fix mathematical problems containing more generalized datasets, an emerging model called q-rung orthopair fuzzy soft sets offers comprehensive framework for number of multi-attribute (MADM) situations but this not capable deal effectively with having bi...

Among the leafy vegetables, lettuce (Lactuca sativa L.) is most widely grown species in world. Wide ranges of physical properties products are used to assess degree maturity. In this study, different varieties were under an unheated plastic tunnel springtime. We evaluated agronomic varieties, condition plants, and determined bioactive substances. Larger head weight can be achieved by ‘King May’...
