TAILIEUCHUNG - Study on the mechanized sowing of wheat under water stressed conditions

Sowing is one of the important agricultural operations for raising crops. After harvest of paddy, if there is deficit moisture in the soil at the time of sowing of wheat, the germination gets affected leading to loss of yield. Handling of water treated seeds by seed drill may open a new gate of opportunities for mechanized sowing of wheat under water stressed conditions, which was the prime objective of the study. Water treated swelled seeds was found to have more weight and volume causing the variations in seed rate and also got crushed while passing through flutted rollers of the seed drill. The total seed damage expressed in percentage varied from 12 to 32 for the different levels of water treatments. Therefore, it is recommended not to use water treated seeds for sowing of wheat by flutted roller type seed metering device. It was also found that with an increase in water treatment rate, seed crushing and internal seed damage rate increased and for this friction generated over wetted seed surface could have been the prime reason. Lubricating oils along with water could be used to treat the wheat seeds in further studies. The study may also be carried out with seed drill having inclined plate type metering device to possibly obtain increase in the germination percentage. | Study on the mechanized sowing of wheat under water stressed conditions
