Abstract

Objective of this study was to examine and evaluate the role of different rates of salicylic acid (SA) as foliar spray on growth and yield performance of BRRI dhan29. The experiment was conducted at Sher-e-Bangla Agricultural University, Bangladesh from November, 2016 to May, 2017 following a randomized complete block design with five rates of SA in six replications. The results showed that the lower rate of SA (upto 0.75 mM) has a positive effect on rice biomass production including effective tiller per hill, filled grain per panicle, grain yield and straw yield. The highest dry matter production at both maximum tillering and panicle initiation stages was found at SA spray rate of 0.5 mM. The highest number of effective tillers per hill (14.7) as well as the highest filled grain (120.4) and grain yield (8.1 t/ha) were found at SA rate of 0.75 mM. However, the maximum biomass production was obtained at SA rate of 0.25 mM. The minimum grain yield (7.0 t/ha) was observed in the control treatment.

Highlights

The most important food for the people of Bangladesh is rice (Oryza sativa L.) and it is the staple food for more than two billion people of Asia (Hien et al, 2010)
A significant variation was observed in the dry matter production of Bangladesh Rice Research Institute (BRRI) dhan29 due to the foliar application of different doses of salicylic acid (SA) at the maximum tillering (MT) and panicle initiation (PI) stages
The lowest oven dry weight was found in treatment T6 which was statistically similar to T1 and T5 treatments

Summary

Introduction

The most important food for the people of Bangladesh is rice (Oryza sativa L.) and it is the staple food for more than two billion people of Asia (Hien et al, 2010). Asia has the largest growing area with top producing countries including China, India, Thailand, Bangladesh and Vietnam (Xiao et al, 2013). It is the most important source of the food energy for 50% of the Global population (Zhao et al, 2011). Rice is a major cereal consumed by the world population, representing about 30% of world production of grains (Yadav and Jindal, 2008). Rice is grown in more than one hundred countries with a total harvested area of nearly 160 million hectares, producing more than 700 million tons every year (IRRI, 2010). 640 million tons of rice are grown on Asia, representing 90% of global production (IRRI, 2010)
