tailieunhanh - Design, fabrication and evaluation of wheel operated sprayer

Now day’s scarcity of labour is creating problem during agricultural operation because in agriculture more labour is required. Pests and weed problems, in crop production are serious both in rain fed and irrigated farms in Chhattisgarh. Farmers are forced to spray insecticides, pesticides and herbicides frequently using manually operated machines, This becomes time consuming poor in application uniformity, laborious, costly and human fatigue is major concern, these problems can be overcome by using manually wheel operated sprayer The objectives of this research saw to manufacture and evaluate wheel operated sprayer. The sprayer was tested both in laboratory and field for the uniformity of application, discharge rate, field capacity and field efficiency and had achieved an application rate of l/ha, with coefficient of variation (CV %) of among the nozzles discharge rate, effective field capacity of ha/hr., theoretical field capacity of ha/hr. and field efficiency of 56%. Based on the performance result the newly developed sprayer can cover one hectare of land within about an hour with a better spray uniformity. | 2020 9 1 1649-1659 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 9 Number 1 2020 Journal homepage http Original Research Article https Design Fabrication and Evaluation of Wheel Operated Sprayer Shambhu Singh1 Suryakant Sonwani1 Trishala Sahu2 1 FMPE Scholar SVCAET RS IGKV Raipur India 2 FMPE BrSM CAET RS Mungeli IGKV Raipur .
