PERFORMANCE OF AEROBIC METHOD ON FIVE VARIETIES OF BORO RICE (Pages : 1 - 9)

A field experiment was conducted at the Agronomy Field Laboratory of Hajee Mohammad Danesh Science and Technology University, Dinajpur during boro season, 2013 to find out suitable rice varieties for aerobic rice cultivation. The treatments comprised of five varieties viz. BR16, BRRI dhan28, BRRI dhan29, BRRI dhan47 and BRRI dhan55 and two methods of planting (conventional transplanting method and aerobic system of planting). The experiment was laid out in randomized complete block design with four replications. Method of planting had significant effect on most of the yield contributing characters and yield. Yield was higher (5.61 t ha-1) in conventional method than aerobic method (5.30 t ha-1). On the other hand, there were significant differences among the rice varieties. BRRI dhan29 gave the highest grain yield (6.53 t ha-1) followed by BR16 (5.84 t ha-1) and the lowest grain yield was obtained from BRRI dhan28 (4.69 t ha-1). The irrigation cost for boro rice was more or less Tk.14450 ha-1 while the additional income from boro rice was only Tk. 4,650 ha-1. So, Tk. 9800 ha-1 was saved when aerobic method was adopted. Due to the looming water crisis situation boro rice production could be sustained by using the technology that requires very less water like aerobic method.Download
