Received: 18-January-2014 ABSTRACT Irrigation is the important factors which determine the productivity of any crop. In this study, the source of irrigation is sewage effluent and observations were recorded on important food crops like pea & pigeon pea. Results showed at higher concentration of effluent there were reduction in growth and yield as compared to diluted conc. (50%) which showed normal growth or without affecting yield, which might be due to lots of organic matter and essential nutrient in sewage effluents. Keywords: Plant Growth, Sewage Irrigation, Crop productivity INTRODUCTION Water scarcity is a severe problem in arid and semiarid regions of the world. Re-use of waste water (sewage effluent) is an appreciable and self controllable source so far irrespective of many impediments and restrictions should be reclaimed. Irrigation with sewage effluent are extensively used throughout world since hundreds of years, also a way of disposal of waste water (domestic waste). Yet it is practiced at a small level in developing countries. In addition to organic nutrient like Nitrogen, phosphorus, it is also having few amounts of heavy metals. Pulses are the most important source of nutrient of vegetarian in India as well other developing countries, wherever increasing population menace made their availability (35 gm per head per day) much lower than recommended (104 gm per head per day by WHO) World Health Organization. Moreover pulses are endowed with capacity to fix atmosphere nitrogen and improve soil fertility. Field pea (Pisum sativinsh) and Pigeon Pea (Cajanus Cajan L.) are the most important pulse crop grown in India both for vegetables and dry seed purpose. Peas have nutritive value and are richer and cheaper source of protein. On an average, it contains 93 calories, 72 per cent moisture 15.9 percent carbohydrates and 20-22% protein in addition to 0.1 g fat, 9.0 mg vitamine, 0.25 mg thiamine, 0.01 mg riboflavin, and 21.5 mg mineral per 100g of edible portion (Bose and Som, 1985). Among winter season pulses, field pea is ranked second after chickpea in India. Pigeon pea on the other hand is an important Kharif legume crop 1 for semi- arid tropics. It ranks first among Kharif pulses and second after gram among all pulse crop with regard to area and production. Irrigation provide moisture, essential nutrients for proper plant growth, so it is an integral part of plant growth regarding source, type as well as frequency of irrigation. 2 The aim of present study is to see the toxicity of sewage if used for irrigation in scarcity of water on Pea and Pigeon pea. In this study we studied all growth parameters in both crops and compared with normal irrigation. MATERIALS AND METHOD In order to observe the effect of sewage on growth and yield of Pea and Pigeon Pea was studied in Arkal and Manak varieties respectively. 30 pots were selected for the experiment, one set of ten pots for control, another for 50% and another for 100% sewage irrigation. Initially for control, irrigation was done with Hoagland nutrient solution and later on with available tap water. Observations were recorded at the regular intervals. BIOLOGICAL YIELD 1.1 Periodic Growth Studies The growth studies were done on 6 randomly selected plants from all pots of a treatment. These plants were tagged for recording of plant height and number of branches per plant. These plants were also utilized for yield attributes studies.
