Intervention effect Normal irrigation gave the highest chlorophyll a and b values.
Intervention effect Normal irrigation gave the highest flag leaf area and plant height.
Intervention effect Normal irrigation gave the highest spike length, spikes per square metre and grains per spike.
Intervention effect Normal irrigation gave the highest grain and straw yields.
Intervention effect Normal irrigation and water deficit at heading or ripening did not differ significantly in chlorophyll a in both seasons.
Intervention effect The reported normal irrigation and water deficit treatments did not differ significantly in grain weight per spike, grain yield and plant height in the first season.
Intervention effect Normal irrigation did not differ significantly from heading deficit in grains per spike and spike length or ripening deficit in spike length in the second season.
Intervention effect Combined ascorbic and salicylic acid sprays gave the greatest chlorophyll a value compared with other treatments.
Intervention effect Combined acid sprays gave the greatest plant height, spike length and spikes per square metre.
Intervention effect Combined acid sprays gave the greatest grains per spike, grain weight per spike and grain yield.
Intervention effect Combined acid sprays gave the greatest straw yield in both seasons.
Intervention effect Combined acid sprays followed the same favorable trend for chlorophyll b in the first season and thousand grain weight in the second.
Intervention effect The 200 ppm plus 200 ppm acid combination gave the greatest flag leaf area in both seasons.
