Effect of SRI methods on the vegetative growth characters of boro hybrid rice cv. Jagoroni

Abstract

An experiment was conducted during January to June, 2003 at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh to study the growth attributes of boro hybrid rice cv. Jagoroni as affected by SRI (System of rice intensification) method and its various modifications. The experiment was laid out in a randomized complete block design with 3 replications. The treatments used in the experiment consisted of 4 soil-water-fertilizer management practices viz. aerated soil condition with NPK fertilizer AS (NPK), aerated soil condition with cowdung AS (C), saturated soil condition with NPK fertilizer SS (NPK), saturated soil condition with cowdung SS (C), and 4 seedling type viz. 16-day-old 1 seedling hill-1(16/1), 16-day-old 3 seedling hill- 1(16/3), 8-day-old 1 seedling hill-1(8/1) and 8-day-old 3 seedling hill-1(8/3). Crop characters studied at vegetative stage of the crop were plant height and number of tillers hill-1. Data revealed that plant height and number of tillers hill-1 studied during vegetative stage varied significantly due to effect of soil-water-fertilizer management practices and seedling (age and number hill-1) treatments. AS (NPK) and 16/1 finally appeared as the best treatments to produce the tallest plant and SS (C) and 8/3 appeared as the worst one. The interaction effect of the treatments appeared to be non-significant in respect of plant height. SS (NPK) and 16/3 produced maximum number of tillers hill-1 while AS (C) and 16/1 produced the minimum one. In case of interaction, SS (NPK) and 16/3 was the best combination and AS (C) and 16/1 was the worst.
