SUMMARYUnder the three levels of submergence (0, 5 and 10 cm. depths), water requirement of rice was maximum at 10 cm. but crop performance was similar to that at 5 cm. With medium and high levels of fertilization the crop had a higher water requirement than under low level, for ‘aus’ and ‘aman’ crops. Compacted soil compared well with puddled soil, but water requirement was appreciably higher with shallow puddling. In the two seasons water requirement, transpiration, evaporation and percolation losses were greater under submergence, and only transpiration was greater under higher levels of fertilization. Transpiration was maximum at flowering stage.

Puddled Soil

A method is described of determining the diffusion coefficient of O2 in undisturbed soil samples. Calculations were made of errors involved when neglecting the storage term, temperature and pressure variations, O2 consumption and resistance of ambient air. The diffusion coefficient (Ds) is a function of air porosity (eg) and soil structure. At values of eg below 0.2, the effect of a puddled soil surface becomes evident. In puddled soils values of Ds at equal eg are far below those in non-puddled soils and the differences increase with decreasing eg. A wet soil crust can severely limit gas exchange by diffusion.

The experiment was conducted at Sher-e-Bangla Agricultural University farm to evaluate the performance of five rapeseed and mustard varieties under two different planting techniques. The planting techniques were as conventional sowing and sowing seeds in puddle soil that assigned to the main plot and five varieties viz. Improved Tori-7, BARI Sarisha -13, BARI Sarisha -15, BARI Sarisha -16 and SAU SR-3 in the sub-plots. Almost all the studied parameters were found statistically similar under two planting techniques except siliqua length that was higher (5.51 cm) in conventional method compared to that of sowing in puddled soil (5.14 cm).  The highest number of siliquae plant-1 (143.67) was obtained from BARI Sarisha -16 that was similar to SAU SR-03 (134.15) and Improved Tori-7 (116.90). The maximum1000-seed weight (4.35 g) was obtained from BARI Sarisha -16 under conventional planting method that was similar to BARI Sarisha -13 irrespective of planting methods. The maximum number of siliqua plant-1 (145.20) was found in BARI Sarisha -16 under conventional planting method that was similar to the same variety in puddle soil (142.13), SAU SR-03 in both the planting method and Improved Tori-7 in conventional method (131.20).  The Improved Tori-7 variety gave the maximum seed yield (2.24 t ha-1) followed by BARI Sarisha -16 (1.96 t ha-1). The highest seed yield was given by the variety BARI Sarisha -16 in conventional planting method (2.39 t ha-1) that was similar to Improved Tori-7 variety irrespective of planting techniques.
