“…Field experiments with spring wheat in low‐N soil showed that only high moisture stress between tillering and boot stages severely reduced dry matter yield, but increased protein concentration. In contrast, medium or late moisture stress did not influence protein concentration 110. Pot experiments showed that water deficit at grain‐filling stage significantly decreased grain yield and nutrient accumulation in winter wheat.…”

Effects of fertilization and other agronomic measures on nutritional quality of crops

Crops, as the basic source of essential substances and nutrients, do not always contain sufficient amounts of these essential nutrients to meet dietary requirements. In this review paper, we discussed the effects of fertilization and other agronomic measures on the nutritional quality of cereal, oilseed and protein crops, tuber plants and vegetables. Research indicates that application of N, P, K and S fertilizers generally increases crop yield as well as nutritional quality. For example, fertilizer increased protein concentration in cereals and pulses, oil concentration in oilseed crops, starch concentration in tubers, and concentration of essential amino acids and vitamins in vegetables. However, excessive fertilizer application, especially N fertilizer, can result in undesirable changes such as increases in nitrate, titratable acidity and acid to sugar ratio, while decreasing the concentration of vitamin C, soluble sugar, soluble solids, and Mg and Ca in some crops. Other agronomic measures, such as tillage and crop rotation, organic farming, soil moisture management, and crop breeding and genetic engineering can also have a large effect on food crop quality, though the potential benefits of these measures for improving crop quality has not been fully exploited. Research literature on this subject suggests that more information is needed in order to achieve an increase in the concentration of essential microelements, prevent accumulation of toxic levels of elements such as Cu, Mo, Zn, Ni, Se and nitrate, and other dangerous or toxic substances and elements in crops.

Cavenell, C. A., DevrosoN 63 73-90. Manitou spring wheat (Triticum aestivum L.) was grown at combinations of three different day/night temperatures (21112'C, 22llz"C and I7ll2'C), rhree levels of fertilizer N (58, 116 and 174 kg N/ha), and three moisture stresses (nominally -0.03, -1.5 and -4.0 MPa) applied for four durations (viz., no stress throughout, stress from (i) four-tiller (Tg), (ii) boot (Bt), or (iii) flowering (Fl) stages to harvest (Hvst)). Plant and soil samples were analyzed at eight growth stages. Plants grown at 22ll2"C or l'7112'C and given 116 tiges plus qu'a tout autre stade, ce qui laisse soupEonner la migration de produits assimilables en compensation de la baisse de produits photosynth6tis6s par la dernidre feuille. Les pertes dues d la respiration associ6e h la translocation des HNS entre la tige et l'6pi sont plus grandes d22112'C qu'it 17ll2'C; la migration des HNS d2'7 ll2"C est apparemment tres lente.

“…The performance of many quality characteristics depends greatly on environmental conditions, which result in differential expression of grain quality from site to site. In fact, grain protein content, perhaps the most important quality feature for wheat, is known to be influenced by climatic parameters, cultivar, nitrogen fertilizer rate, time of nitrogen application, residual soil nitrogen and available moisture during grain filling (Campbell et al, 1981;Rao et al, 1993;Uhlen et al, 1998;Rharrabti et al, 2001). Vitreousness is mainly affected by nitrogen and water availability, and humid environments reduce the percentage of vitreous grains and increase the incidence of black point (Robinson et al, 1979).…”

Cereals are a group of cultivated plants belonging to the grass family that produces grains rich in starch with specific dough properties. These grains are easily harvested, due to the structure and, if under appropriate storage, the mature seeds preserve its qualities and nutritional value for a long time. The gradual shift to a steady-production based agriculture has been the main driving force behind the domestication of wheat, namely durum wheat. The world durum wheat steady-production, which prevails in the Mediterranean region, is mostly used in the production of pasta, yet the quality definition requires the control of fungal phytopathogens, industrial unit operations and additives applications. This paper reviews some aspects of durum wheat production and industrial processing, further considering phytopathogenic infections and the application of food additives.
