INTEGRATED INTER-ROW CULTIVATOR UNIT SUIT FOR VEGETABLE CROPS

This research aimed manufactured and evaluate the developed cultivator unit with modified share suit for vegetables crops inter – row cultivation process, field experiments were carried out on tomato crop planting season 2019 under different operating conditions, at three types of shares used in cultivator unit St (shovel share Duck leg share modified share with wings), four inclination angles of soil sliding knife Sa (Sa1=30ᵒ Sa2=35ᵒ Sa3= 40ᵒ Sa4= 45ᵒ) and three depths of press wheel Wd (Wd1= 2 Wd2= 3 and Wd3= 4 cm.). four measurements achieved : weed erasing efficiency (We %) , weed control efficiency (Wc %), percentage of damaged plants (Dp %) and furrow cross-section profiles, all experimental procedures and measurements were assessed after 30 days from tomato transplanting. The results showed that the highest press wheel depth (Wd3 = 4 cm) with soil sliding knife inclined angle (Sa = 45ᵒ) and wing share obtained high erasing efficiency (We=97%) and highest weed control with regular forming furrow profile, on the other hand duck leg share had highest damage plant percentage (Dp = 1.2%).
