EFFECT OF FERTILIZERS ON THE YIELD, PROTEIN CONTENT AND AMINO ACID COMPOSITION OF WINTER CEREALS

The effect of different fertilizers (nitrogen, phosphorus, potassium) and their combinations on the yield, raw protein content and amino acid composition were studied in field experiments. The levels of treatment were 200 kg/ha for nitrogen, 500-1000 kg/ha for phosphorus and potassium. Winter rye, triticale and wheat cultivar were grown in two subsequent years. Nitrogen fertilization in all cases increased the yield of grains and the raw protein content. The increase reached about 50% in average comparing with control samples grown without adding nitrogen fertilizers. Although there are significant differences between the different cereals studied, it can be generally stated that the increase in protein content is connected with a decrease in the essential to non-essential amino acid ratio. The decrease is higher if only nitrogen fertilizer is used and moderate if a combined treatment with nitrogen, phosphorus and potassium fertilizer is applied

BIOCHEMICAL EVALUATION OF CHICKPEA CAKES AS ADMINISTERED TO ALBINO RATS

Chickpea cakes were prepared according to the procedure of the traditional cake after replacing 0, 25, 50, 75 and 100% of wheat flour by chickpea flour. Ingestion of chickpea cakes did not alter the levels of serum proteins, globulins or albumins. Chickpea cakes had a lowering effect on the serum glucose levels of rats. Serum creatinine and uric acid of different rat groups were within normal limits and did not change in response to chickpea cakes. Chickpea cakes did not affect liver function and had a cholesterol lowering effect either in the rat serum or organs: liver, kidney and heart
