Agricultural experts advise farmers on avoiding yield losses

MULTAN: Agriculture experts have advised farmers not to leave wheat crop water stressed at the stage of formation of crown-like roots to avoid yield losses.

The stage of formation of crown-like roots comes 20-22 days after sowing and lack of water at this stage can cause production losses up to 39%, experts warned in a statement issued by media liaison unit of Punjab agriculture department on Monday.

These roots grow deeper inside soil in search of food and trigger plants’ growth and support subsequent plant structure and fruit formation.

A spokesman from the agriculture department said that wheat crop should get first water 20-22 days after sowing, however, in case of wheat sown on field vacated by paddy, first water be applied some 30-40 days after sowing.

In case farmers have the facility of only one water application, then they should avail it at the time of formation of crown-like roots. Those who failed to apply Nitrogen, Potash and Phosphorous fertilizers at the time of sowing should do so at the time of first water application.
Application of Nitrogen should complete before the fruit formation.

Weaker fertile land should get two bags of DAP or five bags of single super phosphate per acre at the time of first water, however, this quantity should be halved in case of good fertile land. The average fertile land should get one and a half bags of DAP or four bags of single super phosphate per acre.
Phosphorous is an important food ingredient for wheat crop as it increases length of roots, strengthens plant trunk, increases thickness of grain and improve immunity against diseases.

Experts said that proportion of Nitrogen and Phosphorous fertilizers should be 1:1.5, adding that accurate proportion can increase production by five to ten Maunds per acre.

However, application of Nitrogen more than what has been prescribed by experts can be counter productive, the statement concluded.
