tailieunhanh - Tractor drawn rotavator - A comparative study

The field experiment was carried out at college farm to evaluate the performance of tractor drawn rotavator. Based on observations, the soil bulk density after tillage treatment by rotavator (T1) was found g/cm3 which was much lower than that after tillage treatment by harrow (T2) g/cm3 and by cultivator (T3) g/cm3 , the soil moisture value was found to be g per 100 g before tillage and g per 100 g after tillage operations which shows soil moisture content did not differ significantly between treatments, the rotavator improved soil tilth which was evaluated by measuring the MMD of soil clods. | 2018 7 4 2373-2380 EXCELLENT PUBLISHERS International Journal of Current Microbiology and Applied Sciences ISSN 2319-7706 Volume 7 Number 04 2018 Journal homepage http Original Research Article https Tractor Drawn Rotavator - A Comparative Study .

Based on observations the soil bulk density after tillage treatment by rotavator T1 was found g cm3 which was much lower than that after tillage treatment by harrow T2 g cm3 and by cultivator T3 g cm3 the soil moisture value was found to be g per 100 g before tillage and g per 100 g after tillage operations which shows soil moisture content did not differ significantly between treatments the rotavator improved soil tilth which was evaluated by measuring the MMD of soil clods. The MMD mean mass diameter of soil clods in tillage treatments by rotavator T1 was mm. MMD was found significantly larger for harrow T2 mm and for cultivator T3 mm the operational time was higher by and in the case of T2 and T3 and the diesel consumption was higher by and in case of T2 and T3. Introduction Rotavators perform well in suitable soil conditions. One rotary tillage operation may be equivalent to several conventional tillage operations as far as the quality of the seedbed is concerned Verma et al. 1980 . Rotary tillers can replace the plow disk and harrow Manesh et al. 2002 . A negative draft produced by the rotary action results in lower power .
