Cotton (Gossypium hirsutum L.) is the world's most susceptible agronomic crop to various biotic and abiotic stresses. Potassium (K) is the well-known plant nutrient that enhances stress tolerance of plants. This monograph reports K-induced stress tolerance of cotton genotypes and the positive impacts of adequate K nutrition on their growth, yield and K uptake. Adequate K nutrition increased the growth and yield of cotton genotypes by enhancing their resistance against diseases and insect pest infestations. These results advocate that adequate K nutrition can effectively promote low-pesticide-input, environment-friendly sustainable cotton production.

Henna (Lawsonia inermis L.) is one of the most important and historic medicinal crops. However, very little work has been done across the globe and the scientific community and common readers still require much knowledge on its various aspects. Soil salinity plays havoc with the sustainability of crop production around the globe. A thorough information of the salt-tolerance of important crops like henna help understand their sustainable production under salt-affected soils. This monograph focuses upon the salinity tolerance of henna at early growth stage.

Soil microbes are the part and parcel of low-nutrient-input sustainable agriculture around the globe, especially under various biotic and abiotic stresses. In view of the rapid mining of phosphate reserves and the scorching prices of phosphatic fertilizers, this first-ever study highlights the comparative role of ACC-deaminase, phosphate-solubilizing Pseudomonas fluorescens and mycorrhizal fungus Glomus mosseae in improving the growth and yield of mungbean (Vigna radiata L.) under phosphorus deficiency stress.

Phosphorus (P) is an essential nutrient, required for the normal growth and development of plants. Adequate P nutrition plays very significant role in developing efficient root system of plants, especially under P deficiency stress. This field study reports the beneficial effects of adequate P nutrition and biopriming of mustard seed with ACC-deaminase, phosphate-solubuilizing rhizobacteria (Pseudomonas fluorescens) on mustard root architecture and P accumulation of mustard plants and consequently on mustard yield.

Phosphorus (P) is a non-renewable and precious agriculture input in Pakistan and elsewhere. The rapidly vanishing global P reserves appear to be the greatest threat to modern sustainable agriculture and healthy environment. This specific book offers a practical solution to produce wheat under P-deficient soils by utilizing phosphate solubilizing rhizobacteria in integration with chemical P fertilizer. The book is equally good for the students of Soil Science and Agronomy, research scientists and extension workers around the globe.

Potassium (K) is an important nutrient for sustainable maize production. However, due to high cost of fertilizer K, farmers seldom use K for maize nutrition which results in big yield gaps. Hence, the exploration of alternate sources of K nutrition of maize is highly crucial for sustainable maize production. This study evaluates the efficacy of a novel organic K fertilizer, developed from fruits and vegetables wastes, in enhancing the growth and biomass production of maize.

Potassium (K) nutrition ensures optimum yield and quality of crops. This monograph evaluates the impacts of varying levels of K on the growth, yield and K accumulation of two sunflower hybrids, viz. Hyson-33 and Hyson-39, grown at five different rates of K, i.e. 0 (control), 30 through 120 kg/ha. Across genotypes, K nutrition significantly enhanced biomass yield, number of leaves, stem diameter, head diameter, head length, head weight, achene yield and K accumulation at 120 kg K/ha, as against control. Across K nutrition, Hyson-39 had more biomass yield, number of leaves, stem diameter, head diameter, head length, head weight, and achene yield, as compared to Hyson-33. Contrarily, Hyson-33 accumulated more K than Hyson-39. In crux, adequate K nutrition enhanced the growth and achene yield of both sunflower hybrids even under adequate soil K condition, witnessing the importance of K in sunflower nutrition. Hyson-33 responded K nutrition more strongly, with comparatively lower K accumulation, as compared to Hyson-39. A dose of 120 kg K/ha was found to be the best dose in enhancing most of the growth and yield traits of sunflower hybrids.

The rapid mining of soil potassium (K) is the major yield limiting factor in cotton production in Pakistan and elsewhere. Potassium influences cotton yield and quality due to its versatile roles in the physiology and biochemistry of cotton. Interestingly, cotton requires K as much as nitrogen, during entire growth and development, to offer optimum yield. However, in many parts of the world, K fertilization is a very costly agricultural input. Hence, the farming community, especially in developing countries, seldom include K fertilization in crop production programs. Recent literature on K nutrition of cotton has witnessed that K requirement of cotton varies among genotypes. Modern, insect-resistant, high yielding cotton varieties require more K as against obsolete varieties. This monograph reports the comparative K requirement of Bt and non-Bt cotton genotypes and identifies cotton genotypes for their suitability to fit well under low and high K input sustainable agriculture systems. This book is a dependable compendium for the students, teachers and researchers working in the domains of K nutrition of cotton and nutrient-use-efficient genotypes.

Foliar application of plant nutrients appeared to be the most promising tool in modern plant nutrition management. While foliar application provides a quick relief to the plants under the deficiencies of various nutrients, it also helps maintain/improve growth, yield and quality of crops under nutrient deficiency stresses. This monograph emphasizes the role of foliar application of nitrogen as urea in enhancing the nutrient uptake (nitrogen, phosphorus and potassium), yield and quality of wheat.

Potassium (K) is the most influencing plant nutrient in cotton production due to its positive effects on the yield and fiber quality of cotton. However, due to the scorching prices of K fertilizers, the farmers around the globe seldom include K in cotton nutrition program. A variety of strategies are devised for low-K-input sustainable cotton production, including the identification of K-use-efficient genotypes and the integrated use of inorganic and organic sources of K. This monograph focuses upon K use efficiency of cotton genotypes, in a series of hydroponics, pot and field experiments, and how it is affected by inorganic and organic K fertilizers. Various factors affecting productivity of selected cotton genotypes under K deficiency stress are highlighted. Organic and inorganic K fertilizers are compared for correcting K deficiency in cotton. These studies have implications for agriculture particularly in developing countries where K fertilizers are scarce and expensive. This well written and easy to read book is practically useful for undergraduate and postgraduate students, research workers and extensionists.

Phosphorus is the major yield-limiting nutrient, globally. The recent estimates that world’s P reserves end by 2050 compelled scientists to explore the alternate means of crop phosphorus nutrition. The use of ACC-deaminase rhizobacteria for improved crop yield is now well established. However, no study reports the role of ACC-deaminase rhizobacteria in improving wheat yield based up on their phosphate solubilizing activity. The present book focuses up on the possibility of utilizing phosphate solubilizing ACC-deaminase rhizobacteria for sustainable wheat production under low-phosphorus-input agriculture.
