The total seasonal water use during the crop growth period in wheat varied from 209.4 to
505.5mm (Fig 1) from 2015-16 to 2018-19. Water use efficiency (WUE) varied from 6.88 to
14.80 kg ha -1 mm -1 in the IP and 5.62 to 12.13 kg ha -1 mm -1 in FP (Table 1). IP has greatly
improved the yields that enhanced the WUE of wheat as compared to FP plots, though the
crop water use was the same under both conditions (Dhakal, 2021).
Seasonal water use from 2015-16 to 2018-19 in NICRA village
The harvest index was recorded in the range of 60.78 to 62.26 % with the highest recorded
during 2018-19. The application of the IP also improved the additional net returns over the
FP which was observed in the range of Rs. 3420/- to Rs. 8250/-. The IBCR was obtained in
the range of 1.19 to 2.70 from 2015-16 to 2018-19 with IP over the FP.
Conclusion
IP enhanced the yields and water use efficiency of wheat as compared to FP. The locationspecific
crop management is required to bridge the technological gap. Awareness and
motivation among farmers to adoption of improved agricultural production technologies will
result in better yields which will enhance the WUE in wheat with the same amount of
seasonal water use in both IP and FP. IP can also greatly improve the livelihood and
profitability of the farming community of the NICRA villages of Kullu district.
