soil compaction reduces growth of secondary roots, soil aeration and water and mineral uptake by plant, and decreases chlorophyll content as well as root yield and sugar content. hence, the effect of soil compaction on sugar beet yield and sugar content farms determined by penetrometer using 40 plots of 100 m2 in 40 sugar beet field of hamedan, asadabad, malayer and bahar at the depth of 0-80 c...

Ultra-narrow row cotton studies were conducted during 1999 at two field sites in northern Florida. One site was naturally infested with Meloidogyne incognita Race 3 and the other with Rotylenchulus reniformis. The fumigant 1,3-dichloropropene (1,3-D) was applied broadcast at rates of 0, 16, 32, 48, 64, 80, and 96 kg ai./ha in replicated plots before planting Delta Pine 655 BRR cotton in 25-cm-w...

shallot (allium altissimum regel.) is a medicinal, industrial and perennial plant that has underground tubers. it is one of the most important allium species in iran, which normally grows in semi-cold to very cold highlands. because of being a wild plant, shallot is encounter with water deficit during its growth season. therefore evaluation of water requirement of shallot is important. in order...

This study was aimed at analyzing the yield, grain quality and weed infestation of spring triticale sown in 3 tillage systems: a) conventional tillage (CT)-shallow ploughing and harrowing after harvest of the previous crop, ploughing in the autumn; b) reduced tillage (RT)-only cultivator after harvest of the previous crop, and c) no-tillage (NT)-only glyphosate (360 g L-1) after harvest of ...

Damage to cotton by Rotylenchulus reniformis below plow depth was evaluated in a sandy clay loam soil at Weslaco, Texas. In December 1999, 14 holes on 51-cm centers were dug 91 cm deep along the planting bed and adjacent furrow and 2 ml of 1,3-dichloropropene was placed 91, 61, and 30 cm deep as each hole was refilled and packed. This technique eliminated 96%, 81%, and 74% of R. reniformis down...
