Book Description
Maize is the third important cereal crop in Pakistan after wheat and paddy. It is cultivated widely in the temperate, tropical and sub-tropical areas in the world. But, its function adversely affected by intense temperature and less humidity environments, gives rise to interfere in efficient pollination and resulted in failure in proper grain synthesis. In Pakistan the average production of maize is less than other maize growing countries of the world. The less production of maize is not because of cultivar but it was because of insufficient supply of water and nutrients, which are basic needs for getting greater production, and our soils and environmental conditions, are not supportive to provide adequate nutrients to crops especially micronutrients. The book in hand is an attempt to alleviate the menace of low production and have encompasses valuable information on various nutrient concentrations of pre and post harvest soil AB-DTPA extractable P and Zn, soil available SO4-S, leaf P concentration, plants density, maize grain yield of variety Jalal. This book can be an asset for the researchers, planner and agriculture students.

Book Description
Plant Analysis: An Interpretation Manual 2nd Edition is an easily accessible compilation of data summarising the range of nutrient concentration limits for crops, pastures, vegetables, fruit trees, vines, ornamentals and forest species. This information is valuable in assessing the effectiveness of fertiliser programs and for monitoring longer term changes in crop nutritional status. New to this edition: *Volume and scope of information accessed from the literature has expanded several-fold. Interpretation criteria for 294 species have been compiled in the tables from more than 1872 published papers. *New chapter on nutrient criteria for forest species. *Includes guidelines for collecting, handling and analysing plant material. An entire chapter is devoted to the identification of nutrient deficiency and toxicity symptoms.

Book Description
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.
