Abstract:
In our country more than 75% farmer belong to marginal and small category, and “mechanization” for the small farmer is a great challenge. An application of small equipment which can be operated by single person and capable of doing multi operation is the best solution for us. To improve mechanization in the field of spraying and broadcasting, battery operated knapsack sprayer cum fertilizer broadcaster has been developed and are being produced and these are now using in the country. Battery operated knapsack sprayer cum fertilizer broadcaster is used for effective spraying of chemicals and also used as effective broadcasting of granular fertilizer. The parameters like spraying pressure, spray droplets, spray volume, discharge rate, disc rpm swath width, aperture opening position etc. Thus, keeping above discussed matter in view, tests on a battery-operated knapsack sprayer cum fertilizer broadcaster was performed in the laboratory of FMP department, CAET, JAU, Junagadh. For performance evaluation of sprayer, the operating pressure was maintained between 1 to 3.5 kg/cm2. The results were found that average discharge rate was 1658 ml/min, and triangular pattern was obtained as spray distribution pattern. For performing of broadcaster, it was found that at disc rpm 1390-1400 and aperture opening position (1), application rate of 403.25 kg/ha and swath width 5.33 m was achieved. Effective field capacity was 1.19 ha/hr for BOSF broadcaster at a speed of 3.00 km/hr and field efficiency was achieved 74%.
