Influence of different sowing patterns on the productivity and water use efficiency of some lentil cultivar

الملخص EN

A field experiment was conducted during two successive winter seasons of 2018/2019 and 2019/2020 at Giza Experimental Farm of the Agriculture Research Center, Giza, Egypt, to study the effect of different sowing patterns on the productivity and water use efficiency of some lentil cultivar.

Three lentil cultivars i.

e.

Sinai 1, Giza 29 and Giza 51 were planted with different sowing patterns as follows: Broadcast, Drilling(Rows); on ridges Furrow 50 cm, on ridges Furrow 75 cm and on ridges Furrow 100 cm.

The following traits were studied: (1) Growth characters (2) Yield and yield components, (3) Irrigation water use efficiency of lentil cultivars "IWUE ", and (4) Photosynthetic pigment of leaves and total soluble protein content of lentil seeds.

The obtained results could be summarized as follows.

Lentil cv.

"Giza 51" was recorded the highest values of all growth and yield components with all sowing patterns where as Sinai 1 cv.

was recorded the lowest values of all the studied traits in both seasons.

Also, the lowest amount of water consumptive use (WCU) was obtained from sowing method (Ridge-Furrow 75 cm) followed by Ridge-Furrow 50 cm for the three cultivars compared to the traditional planting.

So we recommend cultivation of three lentil cultivars under Ridge-Furrow 75 cm cultivation methods.
