Available in PDF, EPUB and Kindle. Book excerpt: The relationships between zinc, iron, and phosphorus in sweet corn were investigated under field and greenhouse conditions. The soils used in this study (both acid and calcareous) were low in available zinc and phosphorus. The experiments received standard, uniform rates of nitrogen potassium, magnesium, and sulphur. Corn was used as an indicator crop in all experiments. Plant samples from the field experiments consisted of whole plants collected at six weeks and index leaves collected at silking stage, while the middle three leaves were collected at eight weeks from the greenhouse experiment. The plants that showed visual zinc deficiency symptoms contained very high iron contents and responded to applied zinc. When either phosphorus or soil acidity was limiting growth, no response was obtained from applied zinc and the iron levels were low. Applications of phosphorus and lime both apparently induced a zinc deficiency and a high iron uptake by the plant. Under these conditions marked growth responses to applied zinc were obtained and sharp reductions in iron contents of the plants were noted. These results are contradictory to those reported by other workers for the effect of phosphorus and lime on the uptake of iron; normally, these two materials reduce the uptake of iron by the plant. This was actually the case when zinc was adequate but the reverse was true when a zinc deficiency existed. To explain these results, the hypothesis was advanced that one characteristic of a zinc-deficient plant is a high iron content. Although the actual lime and phosphorus effect is probably a reduction of iron uptake, their effect on creating a zinc deficiency and the associated high iron content was most likely the over-riding factor.

Available in PDF, EPUB and Kindle. Book excerpt: Sulphur (S) plays a pivotal role in various plant growth and development processes being a constituent of sulphur-containing amino acids, cysteine and methionine, and other metabolites viz., glutathione and phytochelatins, co-factor of enzymes which contribute to stress repair and amelioration of heavy metal toxicity. Besides, a number of S-containing components are biologically active and, thus, a source for use as medicinal value. The basic global issue before the agricultural scientist and world community is to evolve cultivars and develop methodologies for efficient use of inputs to enhance agricultural productivity. This is particularly true of the developing countries which are going to see maximum rise in population with changing food demands and declining availability of land. Amongst the inputs, nutrients play a crucial role. The major requirement is for N, P and K followed by several micro-nutrients. In this context reports of world-wide S deficiency in the agricultural systems are relevant. The reasons are many. Broadly speaking reduction inS emission, use of S-free N, P and K fertilizers and higher biomass production contributed the maximum. Despite the need for sulphur as an essential plant nutrient and the substantial returns expected from its use, very little attention has been given to fill the gap between supply and demand of S.

Download or read book The Ecophysiology of Plant Phosphorus Interactions written by Philip J. White and published by Springer Science & Business Media. This book was released on 2008-06-03 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phosphorus (P) is an essential macronutrient for plant growth. It is as phosphate that plants take up P from the soil solution. Since little phosphate is available to plants in most soils, plants have evolved a range of mechanisms to acquire and use P efficiently – including the development of symbiotic relationships that help them access sources of phosphorus beyond the plant’s own range. At the same time, in agricultural systems, applications of inorganic phosphate fertilizers aimed at overcoming phosphate limitation are unsustainable and can cause pollution. This latest volume in Springer’s Plant Ecophysiology series takes an in-depth look at these diverse plant-phosphorus interactions in natural and agricultural environments, presenting a series of critical reviews on the current status of research. In particular, the book presents a wealth of information on the genetic and phenotypic variation in natural plant ecosystems adapted to low P availability, which could be of particular relevance to developing new crop varieties with enhanced abilities to grow under P-limiting conditions. The book provides a valuable reference material for graduates and research scientists working in the field of plant-phosphorus interactions, as well as for those working in plant breeding and sustainable agricultural development.
