Other claims from this paper (12)
- Intervention effect Irrigation at 65% AVSMD did not significantly decrease crop growth rate, relative water content or osmotic potential of maize.
- Intervention effect Irrigation at 65% AVSMD did not significantly decrease ear length, ear diameter or rows per ear of maize.
- Intervention effect Irrigation at 65% AVSMD did not significantly decrease kernels per row, 100-kernel weight or grain yield of maize.
- Intervention effect Irrigation at 50% decreased crop water productivity of maize by 9.93% across the two seasons compared with irrigation at 80% AVSMD.
- Intervention effect Irrigation at 80% of AVSMD increased drought sensitivity, the drought susceptibility index and crop water productivity in both seasons.
- Intervention effect Irrigation at 65% of AVSMD reduced WCU by 19.34 to 20.30% relative to irrigation at 50% (control) in both seasons.
- Intervention effect Irrigation at 65% of AVSMD improved crop water productivity by 15.42 to 14.37% relative to irrigation at 50% (control).
- Intervention effect Sowing maize on beds 140 cm apart with hills 25 cm apart (24000 plants per feddan) gave the highest chlorophyll content, dry matter and leaf area index in the two seasons.
- Intervention effect The same sowing pattern gave the highest crop growth rate, relative water content and ear height in the two seasons.
- Intervention effect The same sowing pattern gave the highest ear length, 100-kernel weight and grain yield in the two seasons.
- Intervention effect The bed sowing treatment decreased the drought sensitivity and drought susceptibility indices.
- Recommendation The authors recommend sowing maize on beds 140 cm apart with hills 25 cm apart plus irrigation at 65% AVSMD, which decreased WCU and improved CWP.
