- Abstract
Inconsistent rainfall causes frequent crop failure and farmer vagaries in drought prone regions of India, specifically in the semi arid region of Vidharbha. Traditionally this region is known for growing crops in multiple cropping or intercropping system of two crops, of different phenology. But advancement in agriculture, commercialization and specifically varietal improvements in a few crops, have influenced farmers to grow mono-crops with high inputs. Such reduced diversity in cropping, exposes the farming community in this region to high risks and vulnerability. This calls for evolving appropriate cropping system in each region considering the soils and rainfall patterns amongst other influencing factors. Cropping system is the cropping pattern used on a farm and its interaction with farm resources, other farm enterprises and available technology which determines their make up. Understanding cropping system concepts, the different crop combinations and sequential growth of crops, under different agro-climatic region and macro climate, will help us in identifying the appropriate cropping pattern of the region. Analysis of the physical resources for crop production, their relationship with other resources and the means of increasing the economic yield as well as biomass per unit area, time and resources, are of great significance in evolving the optimum cropping pattern. This manuscript discusses the importance of evolving region-specific optimized cropping system and the means of doing so. It also exemplifies one such means of evolving optimal cropping system for Vidharba region using Earth Observation (EO) derived inputs through better understanding of the various resources, their boundary limits, their inter-relationships and relationships with other resources for maximizing the benefits. Crop growth profiles derived from EO, soil productivity and agroclimatic variables are used in this study.
