EFFECT OF ZERO TILLAGE AND CORN ( Zea mays L.) REMAINDERS ON GROWTH CHARACTERS OF WHEAT PLANTED LATELY ( Triticum aestivum L.)

Abstract

Tow experiments ( Tillage and zero-Tillage) were carried out during 2013-2014 on land sown with corn in previous season. The treatment of corn remainder which added to plots of each experiment include( 0,3,6 and 9 t.h-1) .Each experiment plots was sown wheat var. Sham-6 by using R.C.B.D with three replicates. The leaf area ,flag leaf area, plant dry wheat after( 30,60 and 90 days) after emergence , absolute growth, net photosynthesis and crop characters growth were studied . Results showed a significant differences among treatments in each experiment and in combined analysis. Locations ( experiments) were significantly differed in all characters studied characters. There was on significant interaction between locations and treatments. Control treatment gave the lowest values in all characters and both experiments ,and values gradually raised until the treatment 6 t.h-1 level. The treatment 6 t.h-1level was surpassed other treatments in both experiments and all characters . Values of all characters were reduced in the level of 9 t.h-1 in comparison with 6 t.h-1 treatment in both experiments and in combined analysis . The location zero tillage was surpassed for all characters .
