Effect of tillage system and sowing method on growth and yield of wheat (Triticum astivium L.)‎ for associated weed in dry land

Abstract EN

A field experiment effect of tillage system and sowing method on growth and yield of wheat Triticum astivium L.

for associated weed in the dry land.

was carried out during the agricultural season 2019-2020 in two locations, the first in the Telkaif location (T) district 35 km north of the city center of Mosul, and the second in the Hamdaniya location (H) district 30 km southeast of the city center of Mosul, with different soil texture.

The experiment included two factors.

The first tillage systems: Conventional tillage system (CT) and Zero tillage system (ZT), The second: the Sowing method it includes planting with lines where the space between one line and another is (17, 34, 34×34 cm cross sowing).

The experiment was designed according to a experiment system within (split-plot) using a completely randomized block design(R.

C.

B.

D) and with three replications.

The seeds were sown (variety Tal Afar 3) at a seed rate of 120 kg.

ha-1.

fertilizer was added (NPK 15: 15: 15) 200 kg.

ha-1.

The data were analyzed statistically the mean parameters were compared using the Duncan multi-range test.

The results obtained are summarized as follows: The space (34 cm) and (34 x 34 cm) recored the largest amount of grain yield in both locations, and it was recorded at 427.99 g.

m-2 and 411.15 g.

m-2, respectively, in Al-Hamdaniya, and 474.50 g.

m-2 and 456.03 g.

m-2 for the Tlekif.

The space (34 x 34 cm) was effective in reducing the number and weight of the broadleaf weeds and it was recorded at 113.67 weeds.

m-2 and 113.08 g.

m-2 respectively, in Hamdaniya.
