On natural acidic soil, statistically significant relationships between wheat yield and pigment content in leaves were established (for Chl a r = 0.910…0,949; b 0.925…0,967; for carotenoids 2017 0.887;). Nitrogen fertilizer promoted an increase ( - by 38…43%, 16…22%). At phosphorus application, the of chlorophylls increased 44…83%, 20…37%. The mobile arable layer soil is significantly associate...

BACKGROUND A role of energy and various nutrients, including protein, sugar, saturated and unsaturated fats, in colorectal cancer risk has been suggested, but should be better defined. PATIENTS AND METHODS The association between dietary intake of various macronutrients and colorectal cancer risk was analysed using data from a case-control study conducted between 1992 and 2000 in the Swiss Ca...

Over the last 40 years, a growing body of evidence has accumulated regarding the relationships among consumption of dietary fat, carbohydrate, protein, and energy and risk of chronic disease. The fact that diets are usually composed of a variety of foods that include varying amounts of carbohydrate, protein, and various fats imposes some limits on the type of research that can be conducted to a...

BACKGROUND The role of selected macronutrients, fatty acids and cholesterol in the etiology of prostate cancer was analyzed using data from a case-control study carried out in five Italian areas between 1991 and 2002. PATIENTS AND METHODS Cases were 1294 men with incident, histologically confirmed prostate cancer, and admitted to the major teaching and general hospitals of study areas. Contro...

Selenium is an essential element for humans, animals and some species of microorganisms. In higher plants, however, the role of selenium is still unclear. Because selenium enrichment may influence the nutrient balance of plants, a study was done to test the effects of selenite-Se (Na2SeO3⋅5H2O) on selected macronutrients content in maize (Zea mays L. var. saccharata Kcke. cv. Z3ota Kar3owa) see...
