Abstract/ Executive Summary:

The experiment was done at the Bangladesh Agricultural University Farm, Mymensingh. The investigation was made to evaluate the effect of NPK fertilizers and irrigation on the yield and growth of two fine varieties of tobacco in Bangladesh. Plant characters such as, plant height, plant diameter, leaf length, leaf breadth and leaf thickness were found to be increased significantly for higher doses of NPK fertilizers over control, but the variation was not significant for last two doses of NPK i. e. 100-60-40 and 140-80-60 kg/hectare. Interaction due to irrigation, variety and fertilizers showed significant influences on stem diameter, numbers of leaf per plant and leaf length. Irrigation showed a little effect on leaf length and plant diameter but number of leaves per plant seemed to be varietal characters, but NPK seemed to be the prominent factor influencing on all these plant characters in the interaction Almost all the plant characters were found to be better in the variety Kutsaga-51 and, therefore, out yielded the variety WAF in the experimental conditions.

Objectives:

The present investigation was made to evaluate the effect of NPK fertilizers and irrigation on the yield and growth of two fine varieties of tobacco in Bangladesh

Methodology:

The experiment was done at the Bangladesh Agricultural University Farm, Mymensingh. The soil was sandy loam with PH value of 6.6-6.8 (H₂O, 1: 1:5) Split-plot design was used and each treatment was replicated 4 times. The leaves were harvested by priming method and leaf weight was recorded after 3 days air curing inside a ventilated room, other pertaining data were collected from 10 randomly selected plants. Data Were statistically analyzed and mean differences were adjudged by Duncan's New Multiple Range Test.
