The experiments was conducted to study the effect of speeds and depth of tillage of using moldboard plow 113 with triple three speed 4.45 , 5.14 and 6.35 km .hr-1, also three tillage depths 10 ,15 and 20 cm , fuel Consumption and, fuel Consumption costs , plant length and nook length .A split – split design for plots design was used with RCBD design for sub plots with three replications, the mean values were compared using last significant different (L.S.D) using (SAS,2001) computer program for statistical analysis .The results showed that the increase in depth of tillage with constant speed caused on increase fuel consumption, fuel consumption cost and nook length, but plant length decrease with the increase of tillage depth .Where the increase in the speed with constant depth decrease, fuel consumption , fuel consumption cost and plant length , while nook length increased with speed increase .the depth with10cm gave minimum fuel consumption , consumption cost and nook length record 25.718 L.ha-1 , 257.188Diner.ha-1 and 6.388cm respectively . While the same depth gave the highest value for nook length and total yield of Indian pea 34.368cm, 642.9kg.ha-1 the first speed 4.45km.hr-1 gave the highest consumption and cost and plant length whish was27.047L.ha-1, 270.47Dinar.hr-1, 31.711cm, while the same speed gave the lowest value wish.
