Suggested readings Soil fertility is the key factor in determining the yield and quality of crops. Soil related constraints reduces crop yield and income of the farmers. In recent years, global attention is being given to develop non-conventional crops to increase farm income. Indian Council of Agricultural Research (ICAR) also emphasis for the alternative farming system approach to increase farm income and livelihood. One billion people, mostly in developed countries, rely on the use of medicinal plants to cover all or part of their health care needs. The use of botanical dietary supplements has also increased tremendously over the past few decades. The demand for herbal products are growing rapidly worldwide during last two decades. There is a huge export potential available, one can reap this in international market. There is tremendous potential for the cultivation of medicinal plants in various agro regions of India in view of stable climatic conditions, rainfall, diverse soil types and prevailing cropping systems. Catharanthus roseus L. (G.) Don, belongs to the family Apocynaceae and is a world-wide known anticancer plant used for the treatment of a wide variety of cancers. It can cure diseases like leukemia and diabetes. The plant contains more than 130 phytochemicals, of which two of the most valuable alkaloids are vinblastine and vincristine. About 600 tonnes of Catharanthus roseus roots are exported from India annually to European countries as a raw material for the extraction of alkaloids. The total demand is more than 1000 tonnes of roots annually.…

Hardcover. Zustand: New. Maintenance of soil fertility and productivity is the dire need of present-day farming as the level of soil organic matter is getting depleted due to over use of inorganic fertilizers, lesser use of organic manures, mono cropping, imbalanced fertilizer use etc. The area under multiple nutrients deficiencies are also increasing in recent years. As a result of degradation and depletion of soil fertility, agricultural production in many regions is now failing to show positive response to increasing agricultural inputs. The Bioresource technology as a bio software can solve many constraints of soils and restore the fertility and productivity of crops. To renew the soil productivity, recycling of crop biomass and application of compost is a viable alternative. There is an absolute need to replenish soil by returning its lost share of organic matter which is recognized as a serious threat to sustainability. Huge amounts of bio resources are available in India which could effectively be recycled. Total amount of crop residue in India is estimated at 350 x 106 kg per year. This book offers 10 chapters which comprises potential benefits of various bioresources for the improvement of soil fertility in terms of physico-chemical properties, macro and micro nutrient availability, soil microbes and enzymes, crop growth, yield and plant nutrient uptake.…

Hardcover. Zustand: New. The per capita arable land is declining rapidly due to the demographic pressure, soil degradation, urbanisation and conservation to non-agricultural uses. Exploding population and shrinking arable land and water resources put enormous pressure on the scientists to go in for technologies that can enhance the productivity per unit area. The Indian Soil Scientists in the past have made commendable research relating to inventorisation, Characterization, diagnosis and mapping of different soil but also to quantifying their potentials and developing suitable conservation, reclamation and management techniques for augmenting production. To meet the targeted food production for the next few decades, management of soil resources will be a major challenges for the scientific community. Research is needed in areas of Remote sensing and GIS for land and water use management, reliable estimate of the extend of land degradation, etc. Innovative technologies which can improve soil fertility by means of increasing soil organic matter, micro and secondary nutrient availability and soil resilience. Management of inland and coastal salt affected soils. Advanced research on Integrated Nutrient Management, Alternate land use system involving silvipasture, dryland horticulture and medicinal plants. This book has Seven chapters with contributed papers which will be highly for the scholars, scientists and academicians in the field of soil Science, Agronomy, Horticulture, Botany, Environmental Science, Agricultural Advisors and Research and Development Centers. This book will also be useful for the scholars aspiring for competitive examinations.…
