Abstract:
A field experiment was carried out during
Rabi season of 2012-13 and 2013-14 at Varanasi to investigate the effects of irrigation schedules and moisture conservation practices on wheat (
Triticum aestivum L.). The treatment combination were three irrigation schedule
viz., no irrigation, one irrigation at CRI and two irrigation at tillering and flowering and six moisture conservation treatments
viz., no hydrogel, 4t/ha mulch, 6 t/ha mulch, 2.5 kg hydrogel ha
-1, 5.0 kg hydrogel ha
-1 and 7.5 kg hydrogel ha
-1 were compared with four irrigation at CRI, tillering, late jointing and milk stage as control. Application of two irrigations at tillering and flowering (I
2) resulted in significant increase in CGR (g/m
2/day), RGR (g/g/day), leaf area index and nutrient uptake by crop than I
0 (no irrigation) and I
1 (one irrigation) treatments during both the years. The maximum CGR (g/m
2/day), RGR (g/g/day), leaf area index and nutrient uptake by crop were recorded with M
6 (7.5 kg hydrogel/ha), which was significantly higher than remaining treatments at all stages but it was at par with M
3 (6 t mulch/ha) and M
5 (5 kg hydrogel/ha) at most of the growth stages among moisture conservation practices.
