Study on comparative performance of natural and organic farming in onion (Allium cepa L.) under south Gujarat region
Research Type
Departmental Research
Experiment Background
Organic cultivation offers one of the most sustainable farming systems with recurring benefits not only in long term soil health but also in providing stability in production by imparting better resistance against various biotic and abiotic stresses. Consumer demand for organically grown vegetables is steadily increasing all over the world for both domestic and export market. This drastic change is due to human concern over health which made him to produce pesticide residue and other harmful chemicals-free crops. The challenges are how to produce these crops in ways that are environmentally friendly and without lowering the yield levels achieved by conventional production systems (Prabhakar et al., 2012). Organic vegetables fetch a premium price of 10 to 50 per cent over conventional products (Sridhar et al., 2014) making it attractive proposition for the selective farmers interested in this. Onion (Allium cepa L.) is one of the important commercial bulbous crops cultivated extensively in India covering an area of 1.203 million hectares with a production of 19.4 million tonnes and productivity of 16.10 tonnes per hectare.
In the present scenario, both the state and central Government is focusing on natural/ organic farming for achieving sustainable productivity, food security as well as food safety. Therefore, it is a need to find out the efficiency of natural and organic farming on crop productivity and soil health in onion crop. Keeping above facts in sight, the present experiment is planned.
