Abstract/Description: | The green revolution of the late 1960s, responsible for rapid agricultural growth, was largely confined to irrigated areas bypassing the vast rainfed tracts. Nearly half of the cultivated area in India will remain rainfed even after realizing the full irrigation potential. Rainfed areas produce bulk of coarse cereals, pulses, oilseeds and fiber crops. More importantly, rainfed regions provide livelihood to a majority of rural poor and as a result they are often described as hot spots for civic strife. The productivity of crops grown in rainfed areas is considerably lower than the potential and much lower than that of irrigated crops. Enhancing this productivity is therefore important for growth, equity and sustainability in the farm sector. Crop production in rainfed regions is by nature dependent on monsoon behaviour and is therefore highly risky. Rainfed regions are also highly heterogeneous in terms of land terrain, soil productivity, climate and socio-economic conditions, all of which influence the crop productivity. Another important factor that affects crop production is the incidence of pests and diseases. With the poor capacity of the farmers to invest on plant protection measures, the incidence of pests and diseases often leads to significant losses of productivity and income to the farmers. As an insurance against biotic and abiotic stresses, farmers in rainfed regions have diversified their farming systems. Rainfed regions are thus more diversified in cropping systems compared to irrigated areas. Small and marginal farmers in rainfed areas generally grow more crops per unit area as inter and mixed cropping systems (Walker and Ryan, 1990). These systems, meet the diverse family needs and also are less prone to pests and diseases. As the components in the system differ in their growth behaviour and nutrient and water requirements, it helps in risk minimization. Dependence on chemical pesticides has led to the problems such as insect pest resistance, resurgence and escalating cost of cultivation. Considering the ill effects of chemical pesticides and the growing preference for chemical-free food products, efforts are under way to develop and popularize Integrated Pest management (IPM) technologies. Such technologies need to be affordable by the farmers and should fit into the existing farming systems. Research revealed that farmers adopt such components of IPM as intercropping and border crops more readily. In other words, cultural components of IPM need to be emphasized more as they require relatively less external inputs and are more likely to be adopted by the farmers. Crop diversity is a situation wherein different crops are grown simultaneously. Crop-crop, cropborder and crop-weed diversities are different forms of crop diversity (Baliddawa, 1985). Intercropping and mixed cropping systems are more popular forms of crop-crop diversity practiced in rainfed agriculture. These systems provide situations that are less pest-prone compared to the monocultures. The genetic uniformity of monocultures leads to susceptibility to pests (Bhatnagar and Davies, 1979). The factors that contribute to reduced pest populations |
