EFFECT OF PRECISION LAND LEVELING, PLANTING METHOD AND BIOFERTILIZER APPLICATION ON RICE GRAIN YIELD IN SANDY SOILS
This study was carried out at Kalabsho Region, El-Dakhlia Governorate, during 2006 summer season to find out the effect of precision land leveling and planting method on rice grain yield under biofertilizer application in the sandy soils. The experiment was established and designed statistically as a split split plots with three replicates. The main plots were located for the precision land leveling treatment levels of 0, 0.01, 0.02 and 0.03% slope, comparing with the traditional leveling, the sub plots were devoted for the rice planting methods of manual broadcasting, manual transplanting and mechanical drilling and the sub sub plots were involved the biofertilizer treatment using the Blue green Algae, comparing with the bereaved of biofertilizer. The obtained results could be summarized as follows:
1. The laser control equipment achieved the higher field capacity of 30.45 m3/h at 2.65 km/h forward speed and 0.03% leveling slope, while, the traditional scraper achieved the higher field capacity of 17.68 m3/h at 2.56 km/h forward speed.
2. Applying the precision land leveling under the biofertilization conditions achieve lower values of soil bulk density and soil penetration resistance than the traditional leveling by about 7 and 2 %, respectively.
3. Applying the precision land leveling under the biofertilization conditions achieved higher concentration of the available soil N, P and K than the traditional leveling by about 6, 20 and 8%, respectively.
4. Applying the precision land leveling of 0.02% slope and adobting the mechanical drilling under the biofertilization conditions achieved the higher rice grain yield of 4.18 ton/fed.
Finally, it is recommended to apply the precision land leveling and adobt the mechanical drilling under the biofertilization conditions to achieve higher rice grain yield in the sandy soils.
