Title : Influence of different trash management practices on soil properties under sugarcane ratoon cultivation

Abstract :

Sugarcane crop is a source of income for the rural people but the residue of sugarcane is burnt by them that cause harmful effects on soil and atmosphere. Apart from this if sugarcane residue is retained on the soil as mulch; it conserves soil moisture, improves the soil properties and inhibits the growth of weeds. Addressing this issue, an experiment was conducted to find out the effect of trash management practices on the physical properties of soil under the sugarcane ratoon cultivation. The result revealed that the application of trash in alternate rows (T5) reduced the soil bulk density from 1.53 to 1.436 Mg cm-3. In first year experiment, water holding capacity show higher mean value with trash chopper (T6) and lower with burning treatment (T8). In infiltration rate observation, maximum was recorded in trash mulching in alternate rows by trash chopper (T6) (4.76 and 10.75 cm hr-1) and lowest in control (T1) i.e. 2.06 cm hr-1 in both years that is 296.11 % and 136.52% increase over the control and T8 burning respectively. The soil temperature and infiltration rate was significantly higher in the T8 and T6 respectively. The second year, significantly higher (24.78 ˚C) mean value of soil temperature was recorded with trash burning (T8) while significantly lower mean value (22.24 ˚C) was observed in (T4) compared to all the other treatments. And the application of trash favors the nutrients recycling and improves the soil health.
