In Malaysia, numerous methods have been subsequently established subjected to water-saving irrigation aiming improve the common conventional system. However, among most preferred method, alternate wetting and drying (AWD) adoption are presently in paddy cultivation yet has very limited information, especially locally. Hence, this study intended propose two treatments, namely continuously floode...
Cytokinins may reflect soil water status and regulate rice (Oryza sativa L.) grain filling. This study investigated the changes in cytokinin levels in rice plants and their relations with grain filling under alternate wetting and drying irrigation. Two 'super' rice cultivars were field grown. Three irrigation regimes, alternate wetting and moderate soil drying (WMD), alternate wetting and sever...
We use a three-dimensional lattice Boltzmann model to investigate the spreading of mesoscale droplets on homogeneous and heterogeneous surfaces. On a homogeneous substrate the base radius of the droplet grows with time as t for a range of viscosities and surface tensions. The time evolutions collapse onto a single curve as a function of a dimensionless time. On a surface comprising of alternate...
A field experiment was conducted at the Bangladesh Agricultural University (BAU) to find out possible effects of alternate wetting and drying irrigation (AWDI) on the yield, water use and water use efficiency (WUE) of Boro rice. The experimental layout was furnitured using split-plot design (SPD) with two modern varieties (MV) of rice viz. BRRIdhan 28 and BRRIdhan 29, which received four irriga...
The sustainability of rice productivity in Bangladesh is likely to face major threat due to water shortage during boro (winter season). The conventional transplanted boro rice requires huge amount of irrigation water due to wastage of various means. It is an imperative task that water saving production technology is needed to replace the conventional system for sustaining boro rice production i...
