e0“A field experiment was conducted during 2006–07 at New Delhi to study the performance of 2 Bt cotton (Gossypium hirsutum L.) hybrids”
e1“Increasing IW/CPE ratio from post-monsoon rainfed (0.4 IW/CPE irrigation from sowing to onset of monsoon) to the highest of 0.6 IW/CPE ratio throughout the crop duration increased consumptive use”

Other claims from this paper (15)
- Association The Bt cotton hybrids MRC 6304 and RCH 317 gave similar seed cotton yield, about 2.31 tonnes/ha.
- Association The Bt cotton hybrids MRC 6304 and RCH 317 gave similar net returns, about Rs 30 165/ha.
- Intervention effect Irrigation of cotton at 0.6 IW/CPE ratio recorded taller plants than 0.4 IW/CPE ratio throughout crop duration.
- Intervention effect Irrigation of cotton at 0.6 IW/CPE ratio recorded more boll number (45.4) than 0.4 IW/CPE ratio throughout crop duration.
- Intervention effect Irrigation of cotton at 0.6 IW/CPE ratio recorded higher boll weight (4.34 g) than 0.4 IW/CPE ratio throughout crop duration.
- Intervention effect Irrigation at 0.6 IW/CPE ratio gave higher seed cotton yield (2.55 tonnes/ha) than 0.2 IW/CPE ratio throughout crop duration (2.20 tonnes/ha).
- Intervention effect Irrigation at 0.6 IW/CPE ratio gave higher seed cotton yield (2.55 tonnes/ha) than 0.4 IW/CPE ratio till onset of monsoon (2.05 tonnes/ha).
- Intervention effect Cotton irrigated throughout at 0.6 IW/CPE ratio gave the highest stalk yield, significantly higher than all other irrigation treatments.
- Intervention effect Irrigation at 0.6 IW/CPE ratio fetched an additional net income of Rs 1 500/ha over 0.4 IW/CPE ratio throughout crop duration.
- Intervention effect Irrigation at 0.2 IW/CPE ratio gave higher productivity and income than post-monsoon rainfed crop.
- Association The two Bt cotton hybrids behaved similarly in consumptive use, moisture extraction pattern and water productivity.
- Association Water productivity based on consumptive use and irrigation water applied, and marginal productivity, were highest with the post-monsoon rainfed crop.
- Association Cotton irrigated at 0.4 and 0.6 IW/CPE ratio recorded more water extraction from the top 60 cm.
- Association Crop irrigated throughout at 0.2 IW/CPE extracted more water from deeper soil layers (60–180 cm).
- Association Post-monsoon rainfed crop extracted more water from deeper soil layers (60–180 cm).
