Summary

Field experiments showed that soil compaction did not affect wheat yield significantly under rainfed conditions. Weed population was significantly reduced due to soil compaction. Compaction decreased total moisture use and increased water use efficiency. There was better and profitable utilization of stored soil moisture from the compaction treatments as compared to no compaction treatment.

Placement of nitrogen about 10 to 15 cm deep in the soil directly below the seed resulted in significant increase in the yield of wheat crop grown under rainfed conditions. Weed population was not affected due to nitrogen placement. Total moisture use reduced due to nitrogen placement. Under rainfed conditions, deep placement of nitrogen was important for increasing the efficiency of fertilizer as well as water utilization by wheat crop.
