A BRIEF REVIEW ON THE INFLUENCE OF FLAG LEAF ON CEREALS PRODUCTION

Production in cereal crops is due to some complex physiological and biochemical processes, but is essentially associated with the process of carbohydrate accumulation in the grain filling phase which in turn is attributed to leaf functionalities. A critical stage in the development of wheat plants is the emergence of the final leaf called the flag leaf.  At this point the emphasis of management needs to shift to its protection as the flag leaf is critical for attaining high grain yields. Unlike other leaves in the reproductive phase, flag leaves are the main organ for photosynthesis, providing the main assimilated source for plant growth and spike development and also for sensing environmental conditions conducive to adaptation. This short review aims to analyse some of the most important results from the specialized literature regarding the influence of the flag leaf on cereal production. The main documentation platforms were Google Scholar and Web of Science. The importance of the flag leaf in generating yield in grains is without dispute. Protecting the flag leaf is critical to attaining high yields. The vigil starts as soon as growers are able to recognize when the flag begins to emerge

PRODUCTION PERFORMANCE OF SOME WHEAT VARIETIES IN THE PEDOCLIMATE CONDITIONS FROM SCDA CARACAL

Knowing the particularities of the reaction of the new varieties and hybrids of the crop plants, under different conditions of experimentation is one of the basic activities of the experimental agricultural research and its aim is their judicious choice for cultivation in certain areas. The paper presents the production results obtained from two Romanian varieties of autumn wheat grown under pedoclimatic conditions at SCDA Caracal, under non-irrigation regime, during three years of experimentation. Taking into consideration the variations of the climatic conditions over the years of experimentation, at the same level of fertilization, the productions obtained for the two varieties of wheat recommend their cultivation in the area of the Caracal Plain

FOLIAR FERTILIZATION - AN INTEGRAL PART OF COMPLEX AND INTEGRATED FERTILIZATIONS – A REVIEW

In the context of demographic increase and climate change, the issue of ensuring food security is becoming increasingly important, which is why the use of chemical fertilizers in agriculture is the main means of increasing the quantity and quality of agricultural production. Alongside basic mineral (root) fertilization, which is indispensable, foliar fertilization is a measure of increase both in terms of yields and quality.  Foliar fertilizers provide a surplus of fertilizing elements, especially secondary macroelements and microelements, which allows plants to thrive under optimal conditions and to resist stress factors. Foliar fertilization has become a widespread management tool in directing the nutrition of crop plants, and is often a complementary part of fertilization systems or even seen as an alternative to root fertilization. When applied correctly, foliar fertilization has an interesting potential to manipulate the yield and quality of agricultural production, with low environmental impact and relatively low costs. This review aims to highlight the importance of foliar fertilization for agricultural crops, based on experimental results from the literature, using the platforms Google Scholar and Web of Science for documentation
