Abstract
An experiment was conducted in a field at AL-Qurna shire located at 65 km north Al-Basrah province during 2013-2014 winter season in a Silt, loam soil, to study Role of foliar fertilization on growth and yield of wheat (Triticumaestivum L.) planted at different rate of Seed using four foliar levels of 0, 2, 4, and 6 liter ha-1 which were given the following symbols F0, F2, F3, and F4 respectively. Three levels of seeding rates of 100, 120, and 140 kg ha-1 were used which were given the following symbols R1, R2, and R3 respectively. The experiment was conducted using randomized complete block design in a split plot arrangement with four replications. The subplots plots have been allocated for foliar rates whereas the seeding rates have been allocated for main plots. The experiment consists of 12 treatments resulting from the combinations between foliar and seeding rates.
The results shows that F2 foliar level gave the highest number of spikes of 575.75 spikes m-2 , number of seeds per spike of 77.22 seed spike-1, 1000 seed weight of 41.38 g, seed yield of 8.16 ton ha-1, biological yield of 21.5 ton ha-1, percentage of protein of 14.80 %, and crude protein yield of 1.21 ton ha-1. Whereas F1 level gave the heights spike efficiency of 83.57%. While F0 foliar level gave the highest harvest index of 35.49%.
The result also showed that the R3 seeding rates gave the highest number of spikes of 567.81 spike m-2, spike efficiency of 84.33%, seed yield of 7.95 ton ha-1, and biological yield of 21.05 ton ha-1. The R2 seeding rate gave the highest harvest index of 35.34%. Whereas the R1 seeding rate gave the highest number of seeds per spike of 75.62 seed spike-1, 1000 seed weight of 40.17 g, percentage of protein of 13.86 %. and crude peotein yield of 1.05 ton ha-1.
The (F2 x R3) interaction treatment gave the highest number of spikes of 616.75 spike m-2, seed yield of 8.41 ton ha-1, and biological yield of 23.25 ton ha-1. Whilst (F2 x R1) interaction treatment gave the highest 1000 seed weight of 41.88 g number of seeds per spike of 82.02 seed spike-1. While The (F0 x R3) interaction treatment gave the highest spike efficiency of 85.45%. The (F0 x R2) interaction treatment gave the highest harvest index of 36.09 %. The (F2 x R1) interaction treatment gave the highest percentage of protein of 15.42 %. The (F02 x R2) interaction treatment gave the highest crude peotein yield of 1.23 ton ha-1. |
