Response of Diverse Lettuce Types to Fertilizer Phosphorus

Variation in the response of barley cultivars to nirrogen fertilizer

Diverse types of review studies based on their approach to retrieving and summarizing original findings

 Background: We are living in an era in which different branches of science are growing very rapidly. Therefore, retrieving and summarizing all new valid findings on a specific subject is one of the most important priorities of scientists. The aim of the present article is to categorize different review studies within the health domain based on their approach to retrieving and summarizing ...

The fate of phosphorus fertilizer in Amazon soya bean fields.

Fertilizer-intensive soya bean agriculture has recently expanded in southeastern Amazonia, and whereas intensive fertilizer use in the temperate zone has led to widespread eutrophication of freshwater ecosystems, the effects in tropical systems are less well understood. We examined the fate of fertilizer phosphorus (P) by comparing P forms and budgets across a chronosequence of soya bean fields...

Effect of Phosphorus Fertilizer Rate on Seedcotton Yield and Petiole Phosphorus Concentrations

monly used instruments is a Minolta SPAD (soil plant analysis development) meter. The SPAD meter measures the difference in light absorption at 430 and 750 nm (Wood et al., 1992). The former is the transmittance peak for chlorophyl ‘a’ and ‘b’, and the latter is in the near-infrared region. The instrument converts the difference in light absorption at these two wavelengths into a numerical SPAD...
