Effect of sowing time and irrigation on growth and yield of different wheat genotypes

A field experiment was carried out in split plot design replicated thrice with main plot treatments comprised of six combinations of two dates of sowings and three irrigation levels whereas the six genotypes were kept in sub plots. The delayed sowing on 25th December in comparison to timely sowing on 20th November reduced the plant height, dry weight and leaf area index. About 50 per cent reduction in the grain yield was recorded. The water stress during reproductive or vegetative phase under restricted irrigation caused significant reduction in growth and yield. The PBW-343 was found to have edge over other genotypes as evident from the maximum plant height, dry weight, leaf area index, seed yield, stalk yield and harvest index.
