| Abstract | ||
| Afield experiment was carried out in the autumn season of 2018 in a farmer fields in Golddera in Elton Kobri area in the district of Dibs. A factorial experiment with three replicates was applied using a randomized complete block design each replicate included (12) treatment of the Combination between the studied Factors , The first factor was three plant densities(88888, 66666 and 53333) plant.h-1 and the second factor was 1- (NPK fertilizer at 320kg N.h-1, 200kg P.h-1, 200kg K.h-1, 2-NPK+ additive (8)ton.h-1 sheep residue fertilizer,3- NPK+ addition of humic acid at the rate of (16)kg.h-1, 4- and NPK + spray of marine algae extract rate of 3 kg.h-1) Far trait studied The results showed:- (The Leaf Area of the main clover Leaf, No. Of Plant Ear, No. Of Ear Grains, Weight of 300 Grains, Single Plant Yield (gm. plant-1), grain yield kh/h, Harvest Index, Protein Percentage %) 1- The medium density (66666plant.h-1) surpassed significantly in the number of ear. plant-1 (1.9), weight of 300 grain(46.5g), grain yield (135.4) g. plant-1, harvest index (43.5%), grain yield per unit area(9212.9) kg. h-1 . 2- The NPK treatment and addition of the humic acid surpassed significantly in the number of ear .plant-1,grain yield g.plant-1(1.9,134.1)respectively, while the treatment of NPK+ animal fertilizer surpassed significantly in the number of ear.plant-1(1.8), number of grains .Ear -1 reached(493.6) respectively, except of mineral fertilizer NPK which was significant in grain yield(9799.5kg.h-1) only . 3- The interaction between plant density and organic fertilizer was significantly in all studied traits. The best combination was medium density (66666plant.h-1) and the density (66666plant.h-1) and NPK+ addition of humic acid surpassed in number of number of grains. ear-1, weight of 300 grains, plant yield(g), reachd (489.9 grain.ear-1, 47.1g, 151.3 g. plant-1) respectively | ||
