Abstract:
A field experiment was conducted in Instructional Farm of College of Agriculture, Odisha University of Agriculture and Technology, Bhubaneswar during 2016-17, to study the Productivity and resource use efficiency of rice-rice system under different establishment methods. The soil of the experimental site was sandy loam in texture, acidic in reaction (pH 5.2), low in organic carbon (4.1 kg/ha), low in available nitrogen (160 kg/ha), low in available phosphorus (4.5 kg/ha) and medium in potassium (253.3 kg/ha).The experiment was laid out in Randomized Block Design with nine treatment and three replications. Three establishment methods (DSR, NPTR and PTR) were assigned to nine treatments in different combination. Rice varieties Swarna sub 1 and Lalat were grown in kharif and Rabi, respectively for this experiment. The investigation revealed that in kharif, maximum grain yield (4.8 t/ha), straw yield (5.43 t/ha) and harvest index (0.47) was recorded under PTR method of establishment. However in Rabi, maximum grain yield (6.65 t/ha) was recorded under NPTR-PTR method of establishment which was 30.5% higher than DSR-DSR method. Thus NPTR-PTR method of establishment was found to be the best method as far as productivity and resource use efficiency is concerned.
