ABSTRACT

A pot experiment was conducted at the Net house of Department of Agronomy, Bangladesh Agricultural University, Mymensingh to study the effects of rate of flobond and level of irrigation on yield dimensions of wheat cv. BARI GAM-19 (Sourov). The experiment comprised of two factors (a) rate of flobond viz., 0, 0.5, 1.0, 2.0, 4.0 and 8.0 g pot-1 and (b) three level of irrigation viz., control, one irrigation at 18 DAS, two irrigation at 18 and 55 DAS, three irrigation at 18, 55 and 80 DAS. The experiment was laid out in a completely randomized design with three replications. The study explored that the grain yield of wheat (21.38 g pot-1/3.06 t ha-1) was found highest with 2 g flobond pot-1 (332 kg ha-1). Biological yield (8.41 t ha-1) and straw yield (38.14 g pot-1/5.45 t ha-1) were highest with 4 g flobond pot-1 (664 kg ha ha-1). On the other hand, all types of yield and harvest index were lowest with no flobond. Again considering irrigation levels,  the grain yield (23.88 g pot-1/3.41 t ha-1), biological yield (8.26 t ha-1) and harvest index (41.40%) were highest with two irrigations treatment. Only straw yield (34.15 g pot-1/4.88 t ha-1) was highest under three irrigations. All types of yield and harvest index were lowest with no irrigation. Considering interaction effects, the straw yield was higher (5.75 t ha-1) with 4 g flobond pot-1 (664 kg ha-1) with two irrigations and the lowest one (21.50 g pot-1/4.47 t ha-1) was found in no flobond and no irrigation. Harvest index (43.85%) was higher with 2 g flobond pot-1 (332 kg ha-1) with two irrigations. All most all types of yield and other yield characters were lowest in no flobond and no irrigation.

Key words: Wheat yield, flobond, irrigation regimes.
