Abstract

Global warming and climate change are predicted to have a major impact on rice production, necessitating both adaption and mitigation strategies. Among the agricultural crops, rice is highly vulnerable to climatic extremes such as drought, unseasonal rains, flooding, and high temperature stress. However, there is a dearth of short duration varieties which will fit well into the reduced growing period brought about by the changing climatic and rainfall pattern. With this point of view, a study was conducted at the research field of Bangladesh Agricultural Development Corporation (BADC) situated at Subarnachar sub-district under Noakhali district of Chittagong division in Bangladesh during July-November 2018 to sort out some cultivars for their earliness, adaptability, yield and other agronomic traits. Total 11 Kanihati cultivars viz., Kanihati 1, Kanihati 2, Kanihati 3, Kanihati 4, Kanihati 6, Kanihati 7, Kanihati 8, Kanihati 9, Kanihati 10, Kanihati 11 and Kanihati 12 were tested against the standard check BRRI dhan52. Test materials were arranged in a randomized complete block design with three replications in three blocks. Result reveals that Kanihati 9, Kanihati 7, and Kanihati 3 were qualified for further screening and evaluation processes for few more years as they were 20 days earlier having the yield potentials of statistically similar with BRRI dhan52 Res.

Highlights

In Bangladesh, rice (Oryza sativa L.) is life
Crop performance data gathered from the experiment included (1) days to 50% flowering as a measure for maturity duration, (2) plant height, (3) number of productive tillers, (4) length of panicle, (5) number of grains panicle-1, (7) weight of 1000 grains and (8) grain yield
All data were subjected to analysis of variance (ANOVA), and Duncans' Multiple Range Test compared means at P

Summary

INTRODUCTION

In Bangladesh, rice (Oryza sativa L.) is life It is the staple food of the country’s 160 million people, providing more than two-thirds of dietary calories and more than half the protein intake. Since rice crop is said to be one of the major contributing factors to global warming, growing short duration varieties is one way of reducing such emissions. More emphasis must be given on the development and release of short maturity varieties This way, research on evaluation of short duration varieties will go a long way in contributing to the national crop production as well as in reducing the factors affecting the global climate change. In the wake of looming crisis of global warming and food security issues, development of short maturing crops should receive priority and focus. In this study eleven local Kanihati lines were evaluated to test their performance having the shorter life cycle against standard check BRRI dhan[52]
