Abstract
A field experiment was carried out to study the effect of spraying a sea weed extract with different concentration on growth and yield of two wheat cultivars (Barcelona and IPA99). The planets were fertilized with 40Kg N + 40Kg P hectare−1 as basal application. At the jointing stage the nutritional extract was sprayed with the following concentrations (control, 200 ml, 300 ml, 400 ml, 500 ml/100 liter of water). The experiment laid out was in split-plot RCBD. The concentrations occupied the main plots and, the varieties had the sub-plots with three replicates. Results showed that Barcelona variety out yielded IPA cultivar on the over whole studied traits (plant height, leaf number, flag leaf area, plant dry weight, spike length, number of seed/spikes, weight of 100 grain, grain, and straw yield. The concentration 300 ml/100 liter of water gave the highest means. There was no significant difference between control with 200 ml/100 liter of water and 400 ml with 500 ml/100 liter of water in planet height, number of leaves, planer dry weight, spike length, number of seeds/spikes, weight of 100 grain, grain, and straw yield. Barcelona variety gave 5.16 ton of seed yield compared with 4.83 Ton hectare−1 for 1PA cultivar. The interaction between Barcelona and 300 ml/100 liter of water gave the best results.
