Magnetic treatment has remained a controversial process for antiscale treatment of industrial and domestic water treatment over the past many years. Hence a study was initiated to evaluate the magnetic treatment of irrigation water on growth and yield parameters of cow pea and brinjal using pot and field experiments. Also, the impact of magnetic treatment on water properties and soil moisture were also evaluated. Under pot experiment, the treatments tried are normal water, hard water 150 and 300 ppm, saline water 500, 1000 and 2000 ppm of both control and magnetic treated solutions, respectively. Two permanent magnets with the strength of 1800–2000 G was used. The results showed that magnetic treatment of irrigation water types led to an improvement in crop growth and yield parameters of cow pea. Magnetic treatments tend to reduce electrical conductivity, total dissolved solids and salinity levels of all solutions except normal irrigation water, whereas a definite trend of increase in pH was noticed for all the treatments. Soil moisture study results showed that the differences in soil moisture for days 1–3 after irrigation with magnetized irrigation water were lesser than those for the control solutions. Irrigation with magnetized irrigation water caused higher soil moisture compared with the control for different solution of saline and hard water respectively. In the field experiment with brinjal also the magnetic treatment of normal and saline water improved the yield by 25.8 and 17.0% over control. Scanning electron microscope image analysis results confirmed that under magnetic treated hard water, there was variation in the crystal structure of calcium carbonate. The length of these crystals is more when compared to control solutions. These results indicated the beneficial effect of magnetically treated irrigation water on growth and yield of crops, the properties of water and confirmed the possibility of using low quality water for agriculture.

Food security challenge in India can be addressed to a considerable extent by improving the performance of irrigation systems. Two minor irrigation schemes in the Kozhikode district of Kerala in South India, namely, Kanniparamba and Vellannur, were assessed for their performance in terms of technical and social components. Water availability constraint in crop growth does not exist, as denoted by the high Relative Water Supply values. Irrigation delivery service in Vellannur is better, compared to Kanniparamba, when their relative irrigation supply values are taken into account. The canal system in Vellannur scheme also shows better maintenance, and hence, conveys water more effectively to the farms. Opportunity for saving water exists in the schemes through careful operation of the system and planning the water delivery by considering effective rainfall and crop water requirements. The relevance of initiating farmer participatory activities for management/distribution of the required quantity of water for crops to enable farmers to change from the practice of excess water use and for better water management is evident. This can be achieved by introducing suitable measures to institutionalize farmers’ participation under the minor irrigation schemes, which do not presently exist under the minor irrigation sector in Kerala State of India.
