Preface
Rice plays a unique role in providing food to the majority of the world population. Efforts in the sphere of research and development are being intensively carried out in different parts of the world to increase its area and production per unit area. Such an endeavour is imperative in order to support the ever increasing population. The scenario in food production is changing fast in the country with the advances made in all branches of Agricultural Sciences. However, the science of Agronomy, a specialized subject dealing with all aspects of field crop production, has accelerated the pace of food production, aided by the progress made in understanding the intricate relationships between crop growth and yield, and between crop and its environment of climate, soil, biotic factors and management practices. Here, the post-Independent era has seen a four-fold increase in food production and currently it is over 209 million tones. The ushering of the Green Revolution in the country through introduction of improved high yielding varieties and hybrids particularly of Mexican dwarf wheat hybrid, hybrid sorghum and maize and high yielding varieties of rice derived from parental material from the International Rice Research Institute IRRI , Philippines in early 1960s brought in its wake an array of new techniques in crop production aimed at optimizing plant population, crop geometries, soil fertility management and weed as well as pests and diseases containment. The science of agronomy has made it possible to generate suitable technology for varied agro-climatic regions and integrate the results of other allied sciences, so as to deliver these appropriate innovative and tested practices to the farmers at large. Agriculture has been a mainstay of human being since time immemorial. Agriculture in any form has been practiced in those areas where men have been living permanently. Agricultural development is multidirectional having galloping speed and rapid spread with respect to time and space. Speedy development of agriculture is vital to the progress of our country. For securing maximum crop production, the best use of the available land has to be made and the latest methods of crop husbandry put into practice. But this depends on the availability of scientific information and guidance on all aspects of agriculture in an easily digestible form. Agronomy deals with the principles and practices of crop production and soil management. In its broader sense, it includes crop ecology, crop production, crop nutrition, soil fertility, water management, weed control, seed technology, etc. To be a good Agronomist, one needs to have a sound knowledge of all these agronomic aspects and also some related aspects from other sciences. After introduction of modern varieties of various durations with improved plant types along with improvement of input resources, farmers started using improved cultural practices
in intensive cropping systems with labour-intensive programmes to improve production per unit land, time and input. In the history of research on tropical rice, the development of plant type based high yielding varieties HYV was an important landmark. Their wide adoption coupled with increased use of fertilizer has helped double rice production in Asia. Several countries including India attained self sufficiency in rice and food. For more than five decades, Dr. K. Ramiah made many and varied contribution to contributions to rice research and development. His pioneering research work on rice genetics, his foresight in establishing a standard system of nomenclature and symbols for genes necessary for the development of linkage maps, his example of applying the science of genetics in breeding efforts for the evolution of now time-tested varieties and many more have deservedly earned a special place for him in the field of rice genetics and breeding. His concern for improving rice production in Asia, where rice is the source of food and employment for the poorest of the world, is evident from a variety of research and developmental strategies
