Performance Evaluation of Five Boro Rice Cultivars Based on Some Morpho-chemical Characters

Abstract

Aim: To study the performance of five Boro rice cultivars based on some morpho-chemical characters. Design: The experiment was laid out in Randomized Complete Block Design (RCBD) with three replications. Place and Duration of Study: The experiment was carried out at the research filed of the department of Agricultural Chemistry, Hajee Mohammad Danesh Science and Technology University, Dinajpur, during the period of February to May, 2014. Methodology: The morpho-chemical performance of five selected Boro rice cultivars viz. BINA dhan 7, Hybrid SL-8H, Poshusail, Jirasail and Swarna were evaluated. Results: The experimental results elucidate that leaf Proline content as well as mineral content was varied amongst the studied cultivar at pre-flowering stage. Results of the study revealed the morpho-chemical, yield and yield attributes were significantly differ of the studied cultivars. The hybrid cultivars showed short plant height, high tillering ability, much leaf number and higher number of grains panicle-1 which support superior growth characters and yield (8.42 t ha-1). Among the cultivars, hybrid rice cv. SL-8H produced the highest yield and higher chlorophyll-a, phosphorus content. Conclusion: From the present study it may be concluded that Hybrid SL-8H showed the highest yield potential than those of Boro rice cultivars. Therefore, it can be suggested that Hybrid SL-8H might be selected for cultivation in Northwest Bangladesh using modern agronomic practices due to its high yield potential but further study is suggested.
