Abstract

Cotton is one of the principal commercial crops in India with 9.5 million ha cultivated area which is largest in the world. India is second largest producer of cotton in the world though the yield is only 300 kg/ha as against the world average of 558 kg/ha, due to poor control of insect pest and dry land farming conditions. During pesticide application most of the pesticide is lost through drift. A major reason for such a pesticide loss is insufficient nozzle pressure, nozzle discharge, nozzle height etc. Hence, it is necessary to determine the optimum discharge rate and pressure so as to reduce the pesticide losses from sprayer. Therefore, the hydraulic boom sprayer was tested using the spray scanner and droplet analyzer in the laboratory for cotton crop to study effect of nozzle discharge rates (0.45, 0.70, 0.90 and 1.35 l/min) and nozzle pressures (275.8, 413.7, 551.6 and 689.5 kPa) on spray uniformity. From the study it was found that nozzle discharge rate of 0.9 l/min and nozzle pressure of 689.5 kPa produced more uniform spray with droplet size of 122.53 to 284.80 μm, droplet density of 17 to 29 drops/cm2 and uniformity coefficient of 0.99 to 1.23.

Abstract

Twin wheel hand hoe is an intercultural tillage implement which is used in arable field and garden. Twin wheel hand hoe has a huge capacity for controlling weed and intercultural preparation. Additionally twin wheel hand hoe has a capacity to aerate the soil. Direct weeding of row crop in puddle soil, alternative to weeding offers the advantage of faster and easier operation with reduce labour and therefore, results into higher work rate. Manual hand weeder developed by researchers are been popularized to address the issue of the timeliness and reducing drudgery in manual operation to proved an alternative to cutting of weed the design and development of blade type cutting mechanism was taken up. The drawings of various components and assemblies of twin wheel hand hoe were prepared utilizing CAD CAM facilities and fabrications of component were done as per the drawing in the researcher work. The field studies were conducted with different thrust on weeder. The variation in weed cutting rate depended on quantity of weeds in the field, thrust on weeder, water holding capacity of soil etc.
