| Abstract | ||||
| In Egypt the fertilizer in wheat are generally applied as broadcast before and during seeding. This is wasteful method of fertilizer application as only 15-20% of applied fertilizer is utilize by wheat crop. The present investigation aim to modify seed drill to placement fertilizer at desired depth sub seeds. The modified seed drill provided with fertilizer opener fixed between every two seed furrow opener in order to seed and fertilizer drilling at different depths and covering the seed and fertilizer simultaneously in a single operation. During the field testing, observations such as depth of seed and fertilizer placement, vertical distance between seed and fertilizer, germination capacity, plant emergence and population plant stand seed and fertilizer rates are recorded. The modified seed drill could be used for seeding a variety of crop. Which could result in 40% and 33% saving of Phosphates and Nitrogen fertilizer respectively also increased plant population by 30% and 14% compared with seeding and applied fertilizer by seed drill and seeding by seed drill and broadcast fertilize. | ||||
