The causes, effects and alleviation of micronutrient deficiencies in crops in: Australia, India, China, Turkey, the Near East, Africa, Europe, South America and the United States of America, are covered, and these are representative of most of the different conditions under which crops are grown anywhere in the world. Micronutrient deficiencies in crops occur in many parts of the world, at various scales (from one to millions of hectares), but differences in soil conditions, climate, crop genotypes and management, result in marked variations in their occurrence. These effects could be attributed to higher accumulation of micronutrients and macronutrients in soil and plant, when the mean values were highly significant as indicated by the present study.Publisher: Springer Science & Business MediaĪ deficiency of one or more of the eight plant micronutrients (boron, chlorine, copper, iron, manganese, molybdenum, nickel and zinc) will adversely affect both the yield and quality of crops. The growth and yield characters of rice crop were not improved by irrigation with UWW and TWW however the high concentration of trace metals affected by lowering the growth and yield (number of grains/panicle, weight of 1000 seeds and yield/plant) attributing factors when irrigated by UWW and TWW as compared to GW control. Great changes in soil properties due to irrigation with UWW and TWW were observed. The wastewaters according to FAO system of water quality classification were found suitable for use in leaching and irrigating saline soils especially for short duration crops. Plant height, tiller panicle length, number of tillers per plant, weight of 1000 seeds and yield/ plant were used as indicators. Soil samples were collected from 0 - 60 cm depths were analyzed for pH, EC, nutrient and heavy metals contents. Experimental was in randomized complete block design with 3 treatments with 3 replicates. Treatments included untreated wastewater (UWW) treated wastewater (TWW) and ground water (GW) as control. Effect of irrigation with untreated and treated wastewater from Vidyaranyapuram sewage treatment plant station on growth and yield of rice as also in enrichment and bio accumulation of nutrients and metals in soil and rice plant in Vidyaranyapuram area in the South West of Mysore, Karnataka was selected.
