Abstract:
The experiment was conducted in the Agronomy Field, Sher-e-Bangla
Agricultural University (SAU), Dhaka-1207 during the period of November 17,
2016 to March 290, 2017 to Growth and yield performance of selected wheat
genotypes at variable irrigation management as influenced by different
varieties and different irrigated and non irrigated condition. In this experiment,
the treatment consisted of three varieties viz. V
ii
1
= BARI Gom 26, V
= BARI
Gom 28, V
3
= BARI Gom 30, and four different irrigations condition viz. I
=
No Irrigation throughout the growing season, I
= One irrigation (Irrigate at
CRI stage), I
2
1
= Two irrigation (Irrigate at CRI and grain filling), I
= Three
irrigation (irrigate at CRI, booting and grain filling stages). The experiment
was laid out in two factors Randomized Complete Block Design (RCBD) with
three replications. The collected data were statistically analyzed for evaluation
of the treatment effect. Results showed that a significant variation among the
treatments in respect majority of the observed parameters. Results showed
significant variation in almost every parameter of treatments. The highest Plant
height, number of effective tillers hill

, spike length number of grain spike
was obtained from BARI Gom-30. The highest grain weight hectare
(1.37
ton) was found from wheat variety BARI Gom-30. All parameter of wheat
showed statistically significant variation due to amount of irrigation. The
maximum value of growth, yield contributing characters, seed yield was observed
with three irrigation (irrigate at CRI, booting and grain filling stages). The
interaction between different levels of variety and irrigation was significantly
influenced on almost all growth and yield contributing characters, seed yield. The
highest grain yield (1.93 t ha
-1
) was obtained from BARI Gom-30 with three
irrigation (irrigate at CRI, booting and grain filling stages). The optimum
growth and higher yield of wheat cv. BARI Gom-30 could be obtained by
applying three irrigations at irrigate at CRI, booting and grain filling stages.
