Book Description
Scientific Study from the year 2017 in the subject Agrarian Studies, grade: 1.5, Mar Augusthinose College, course: Biotechnology, language: English, abstract: Black pepper belongs to piperaceae family and is known as "king of species." This piperaceae family contain approximately 2,000 species. Phosphorus is one of the most important micronutrients and they are essential for the biological growth, development of plants and it is the most essential nutrient for plants. Phosphate deficiency is wide spread and phosphate fertilizers universally required in the form of inorganic P fertilizers, only a small portion is utilized by plants and the remaining are in insoluble form and they are solubilised by the microbes present in the soil. Soil, they are rich in micro and macronutrients and sixteen elements or nutrients are essential for plant growth and reproduction. Several soil bacteria, particularly belonging to the genera Pseudomonas and Bacillus posses ability to bring insoluble soil phosphate into soluble forms by secreting acids like formic, lactic and acetic. The rhizosphere soil sample were serially diluted up to 10-4 using sterile distilled water and plated on Pikovskaya's agar medium by pour plate method. The P solubilising isolates was evaluated on agar plates of Pikovaskya growth medium by solubilising the tricalcium phosphate of the medium. After incubation the phosphate solubilising microorganisms were selected based on different colonies. Out of so many bacterial isolates, 8 isolates were selected for the further study to perform qualitative and quantitative analysis. Phosphate solubilising microorganisms are possible to use as bio fertilizer for all crops. Among the isolates some of are almost identical in biochemical test but they have different morphology characters.

Book Description
Black pepper (Piper nigrum) the flowering wine belongs to the family piperaceae, cultivated for its fruit, which is usually dried and used as spice and seasoning. The black pepper high variability was also noticed for yield contributing characters like runner shoot production, holding capacity, adventitious root production, lateral branch habit, spike length, number of spikes per lateral branch, fruit set, dry weight. Pharmacological, toxicological, clinical applications and general uses of pepper are bioavailability enhancement, carminative, anti-cancer, natural antioxidant, black pepper as an anti-Inflammatory drug, cholesterol lowering and Immune enhancer, anti-pyretic, anti-periodic and rubefacient, black pepper Improves digestion and promotes intestinal health, preservation of the flavour content. Four different pepper varieties in Kerala were selected based on a baseline survey. The proximate composition includes estimation of dry matter and moisture content, estimation of crude protein, estimation of crude fibre, estimation of crude ash and insoluble ash, ether extract, determination of dietary fibre, gross energy, analysis of component of different varieties of Piper nigrum were determined. The sample Munthirimunda fruit has high moisture content. The sample Chengannor leaf has high dry matter content. The sample Chenganoor leaf has high crude protein content. The sample Panniyor leaf has high crude fibre content. Ether Extract is high in sample Chenganoor leaf. The sample Munthirimunda leaf has high comparatively high Total Ash content. Gross Energy is high in sample Panniyor fruit. A wide gap in the nutritional properties of Piper nigrum varieties exist in Kerala which could be further explored.

Book Description
Great attention has been paid to reduce the use of conventional chemical fertilizers harming living beings through food chain supplements from the soil environment. Therefore, it is necessary to develop alternative sustainable fertilizers to enhance soil sustainability and agriculture productivity. Biofertilizers are the substance that contains microorganisms (bacteria, algae, and fungi) living or latent cells that can enrich the soil quality with nitrogen, phosphorous, potassium, organic matter, etc. They are a cost-effective, biodegradable, and renewable source of plant nutrients/supplements to improve the soil-health properties. Biofertilizers emerge as an attractive alternative to chemical fertilizers, and as a promising cost-effective technology for eco-friendly agriculture and a sustainable environment that holds microorganisms which enhance the soil nutrients' solubility leading a raise in its fertility, stimulates crop growth and healthy food safety. This book provides in-depth knowledge about history and fundamentals to advances biofertilizers, including latest reviews, challenges, and future perspectives. It covers fabrication approaches, and various types of biofertilizers and their applications in agriculture, environment, forestry and industrial sectors. Also, organic farming, quality control, quality assurance, food safety and case-studies of biofertilizers are briefly discussed. Biofertilizers' physical properties, affecting factors, impact, and industry profiles in the market are well addressed. This book is an essential guide for farmers, agrochemists, environmental engineers, scientists, students, and faculty who would like to understand the science behind the sustainable fertilizers, soil chemistry and agroecology.

Book Description
Phosphorus is an essential and major nutrient for microorganisms and plants. Phosphorus influences plant growth and productivity throughout the world. Also it is an essential component of DNA and RNA in biological systems. Since most of the compounds of phosphorus occurring in nature especially in soils are insoluble, microorganisms, in particular, rhizobacteria play a significant role in the solubilization of these compounds. Hence the present study on phosphate-solubilizing bacteria in the rhizosphere of foxtail millet is essentially concerned with the following aspects: Isolation and enumeration of populations of phosphate-solubilizing bacteria from the rhizosphere and non-rhizosphere soil samples of foxtail millet. Purification and identification of the representative isolates. Estimation of the extent of solubilization by the different isolates of the phosphate-solubilizing bacteria. Seeds of 3 different varieties viz., Chitra, Lepakshi and Prasad were treated with individual inoculation of both bacteria and after 3 days of incubation seeds were sown. Shoot length was observed in respective concentrations i.e., 10-1 to 10-7 dilutions."

Book Description
This book provides a comprehensive description of phosphate solubilizing microorganisms and highlights methods for the use of microphos in different crop production systems. The focus is on understanding both the basic and applied aspects of phosphate solubilizing microorganisms and how phosphorus-deficient soils can be transformed into phosphorus-rich ones by applying phosphate solubilizing microorganisms. The interaction of rhizosphere phosphate solubilizing microorganisms and environmental variables, as well as their importance in the production of crops such as legumes, cereals, vegetables etc. are discussed and considered. The use of cold-tolerant phosphate solubilizing microorganisms to enhance crop productivity in mountainous regions is examined, as are the ecological diversity and biotechnological implications of phosphate solubilizing microorganisms. Lastly, the role of phosphate solubilizing microorganisms in aerobic rice cultivation is highlighted. This volume offers a broad overview of plant disease management using phosphate solubilizing microbes and presents strategies for the management of cultivated crops. It will therefore be of special interest to both academics and professionals working in the fields of microbiology, soil microbiology, biotechnology and agronomy, as well as the plant protection sciences. This timely reference book provides an essential and comprehensive source of material, as it includes recent findings on phosphate solubilizing microorganisms and their role in crop production.
