Modeling the Growth and Development of Sorghum and Pearl Millet uri icon

abstract

  • The 1980s have witnessed substantial increases in food production.This has raised expectations that improved systems offarming will be rapidly adopted by small farmers in developingcountries. The agroecological environment of such farms isfragile and the farmers are resource-poor. Therefore, strategiesrecommended for increasing food production must be ecologicallysound and should result in sustainable agriculture.System modeling can greatly expedite the search for improveddevelopment strategies. Recent advances in crop modelinghave made it possible to simulate yields and growth of severalcrops under varied soil and weather conditions with differentmanagement practices. This bulletin describes the frameworkof CERES (Crop Estimation Through Resource and EnvironmentSynthesis) models developed by the International BenchmarkSites Network for Agrotechnology Transfer ( IBSNAT)and The International Crops Research Institute for the Semi-Ar i d Tropics ( ICRISAT) . Recent wor k on the simulation ofnitrogen transformation in soils at the International FertilizerDevelopment Center ( IFDC) is discussed. A section on riskanalyzes the cost-benefit implications of various inputs forincreased crop production. RESCAP?a resource capturemodel developed at ICRISAT Center is presented.This publication is a cogent source book on the current statusof development of CERES and RESCAP models, their dataneeds, outputs, and applications
