Consequence of foliar application treatments with Npk on productivity of bread wheat [electronic resource]

Includes bibliographic reference

A field experiment was conducted during 2020/2021 winter season in a special field South of Baghdad in the district of Kothi (Jableh) Al-Hamiri region, North of Babil Governorate, to study consequence of some foliar appliance treatments by way of nitrogen, phosphorus in addition to potassium (NPK) on productivity of bread wheat Ibaa-99 cultivar. The experiment was conducted in a Randomized Complete Block Design (RCBD) in three replications. The considered foliar application treatments were as follows; without spraying, spraying with nitrogen at 4000 mg L-1, phosphorous at 2000 mg L-1, potassium at 4000 mg L-1 and the mixture of nitrogen, phosphorous and potassium. Spraying wheat plants with the mixture of nitrogen (4000 mg L-1), phosphorous (2000 mg L-1) and potassium (4000 mg L-1) fertilizers significantly increased growth, yield and its components as compared with other studied foliar application treatments. The second-best foliar application treatment was spraying wheat plants with nitrogen at 4000 mg L-1, go after by spraying plants with K at 4000 mg L-1, then spraying plants with P at 2000 mg L-1and lastly control treatment (without foliar application). It may well be decided that spraying wheat plants with the mixture of nitrogen at 4000 mg L-1, phosphorous at 2000 mg L-1 and potassium at 4000 mg L-1 to improve growth, yield and its components of bread wheat Ibaa-99 cultivar under the environmental conditions of studying area stage under the environmental conditions of studying area.
