Other claims from this paper (17)
- Intervention effect Spray of growth regulators along with 100 to 150% of recommended N significantly decreased wheat plant height and ultimately reduced lodging.
- Intervention effect Maximum wheat grain yield (4.40 t/ha) was recorded with 100% N, statistically at par with 100 and 150% N plus growth regulators but significantly higher than the remaining treatments.
- Observation Wheat lodged in plots with N at 125% of recommended, with a lodging score of 5.23.
- Observation Wheat lodged in plots with N at 150% of recommended, with a lodging score of 12.53.
- Intervention effect Growth regulator application gave significantly higher wheat yields only when the crop lodged or at lower N levels.
- Observation Highest net returns of ` 85,114/ha were recorded at 100% N.
- Observation The highest B:C ratio (2.73) was recorded at 100% N.
- Observation The highest energy productivity (256.9 g grain/MJ) was recorded at 100% N.
- Observation The highest energy responsiveness (7.84 MJ/Re) was recorded at 100% N.
- Observation The highest agronomic N-use efficiency (20.5 kg grain/kg N applied) was recorded at 100% N.
- Observation The highest physiological N-use efficiency (38.5 kg grain/kg N uptake) was recorded at 100% N.
- Observation The highest apparent recovery efficiency (66.5% N uptake/kg N applied) was recorded at 100% N.
- Observation The maximum energy ratio (9.46) was obtained with 100% N plus growth regulators.
- Observation The maximum nitrogen harvest index (75.0%) was obtained under 75% N.
- Observation The maximum total N uptake (125.7 kg) was obtained with 150% N plus growth regulators.
- Observation The maximum crude protein yield was obtained with 150% N plus growth regulators.
- Intervention effect The authors conclude that growth retardants (0.2% chlormequat chloride + 0.1% tebuconazole) shortened wheat plants and reduced lodging but did not improve productivity and profitability under restricted irrigation.
