Investigation of Morpho-chemical Characteristics and Yield Potential of Five Local Rice Cultivars

Aims: To study morpho-chemical, yield and yield contributing characteristics of five local rice cultivars viz. Red Swarna, Jota pari, Pariza, Sugandhi and ShaitaBoro.

Study Design: The experiment was laid out in Randomized Complete Block Design with three replications.

Place and Duration of Study: A field experiment was conducted at the farm laboratory of Agricultural Chemistry Department, Hajee Mohammad Danesh Science and Technology University, Dinajpur, Bangladesh during the period from February to May, 2014.

Methodology: The total experimental area was divided into 3 blocks. Each block was then subdivided into 5 plots. The plot unit area was 2 m x 2 m. The replications were separated from one another by one meter border. The border between the individual plot was 0.5 m. All the intercultural operations were done as when necessary. Data on different characteristics were collected at different growth stages.

Results: Results revealed that morphological, physiological; yield and yield attributes were significantly different among the cultivars studied. The Sugandhi produced higher number of grains per panicle and bolder grains which resulted higher grain yield. Further, Sugandhi showed superiority in yield contributing characteristics: total tillers number, filled grain per panicle over other local cultivars and it also produced higher grain yield (4.86 t per ha).

Conclusion: It is revealed that Sugandhi had the higher yielding ability than those of other local cultivars.
