Intensification, sustainability, optimizing scarce resources, and climate change are among the key issues. Organiz

Designing improved plant types: a breeder’s viewpointver the last 30 years, have extended this traditional approach to encompass considerations of the basic processes of dry matter accumulation and distribution. In some cases this extension has involved a breeding approach based explicitly on the design and selection of model plants or ideotypes. This

Designing improved plant types for the semiarid tropics: agronomists’ viewpointsnt types. In this paper, simulation models of the contrasting crops, sorghum, maize and kenaf, and long-term climatic data were used to assess the value, in terms of both yield and risk, of different plant designs at a semiarid site in northern Australia..The impact of three crop improvement strateg

Simulation in pre-testing of rice genotypes in Tamil Nadus involves considerable time and effort. To reduce time and expense, we sought to employ a crop growth simulation model that explains the interaction of environment and genotype..Field experiments were conducted at Tamil Nadu Rice Research Institute (TNRRI), South India, during the 1990 wet season t

Agro-ecological zoning using crop growth simulation models: characterization of wheat environments oof agricultural potential of a region, planning for regional development and identification of research priorities. Conventional methods employed are overlaying of maps and various statistical techniques. The major quantitative output of these approaches is growing period calculated from rainfall an

An agroclimatic approach to agricultural development in India More than three-fold increase in production has been achieved by commodity-oriented programmes involving major technological breakthrough. This resulted in heavy exploitation of natural resource stock without looking at alternative perspectives. Thus major associated problems like linear flow of na
