Effects of Diazinon on Nutrient Availability of Indian Spinach under Different Doses of Rice Hull

Indian spinach (Basella alba) originates from Asia but is now grown in most tropical regions as a leafy vegetable crop. It is usually cooked but can also be used raw in salads. Rice hulls (or rice husks) are the hard protecting coverings of grains of rice. In addition to protecting rice during the growing season, rice hulls can be put to use as building material, fertilizer, insulation material, or fuel. Rice hulls are the coatings of seeds or grains of rice. In medium land, rice even under puddled conditions during the critical period warranted an effective as well as economic weed control practice to prevent reduction in rice yield due to weeds that ranged from 28 to 48% [1]. Diazinon is used in agriculture to control insects on fruit, vegetable, nut and field crops. Evidence shows that intake of fruit and vegetables regularly reduce the risk of cancers, high blood pressure, heart disease, diabetes, stroke, and other chronic diseases. Only cereal production in Bangladesh reduced at 0.20 million tons in 1992 which was nearly 6 million tons in 1950 [2]. Such success was possible due to the use of pesticides for effective protection against pests and diseases along with other modern agricultural attributes. With the intensification of agriculture and increasing usage of pesticides, there is an urgent need to study the side effects of pesticides on various soil properties and on the host plant. Currently sprayed liquid insecticides are being causing deaths of Childs in fruits garden area of Bangladesh [3].
