Abstract/ Executive Summary:

The experiment was conducted at the Horticulture Farm of the Bangladesh Agricultural University, during the period from September, 1977 to April. 1978 with a view to finding out the appropriate time of planting of onion bulb for seed production under the agroclimatic condition of Mymensingh. The bulbs were planted on four different dates which were 13th October, 23rd October, 3rd November and 13th November. Both the yield and the quality of seeds were found to be the highest when the bulbs were planted on 23rd October. The early planting as well as planting on later dates was found to produce seeds inferior in quality and smaller in quantity.

Keywords: Onion Bulbs, Yield and Quality of Seeds

Location: Horticulture Farm of the Bangladesh Agricultural University, Mymensingh.

Start Date: 30-09-1977

End Date: 00-04-1978

Program Area: Crop-Soil-Water Management

Commodity: Onion

Objectives:

To find out the most suitable time of planting of onion bulb for seed production under the agroclimatic condition of Mymensingh.

Methodology:

The study was conducted at the Horticulture Farm of the Bangladesh Agricultural University, Mymensingh during the period from 30th September, 1977 to the middle of April, 1978. The soil of the experimental plot was an alluvial sandy loam and of fairly good inherent fertility. The crop was fertilized with manures and fertilizers as recommended. Irrigation, weeding and other cultural operations were done as and when required. The experiment was laid out in the randomized block design with four replications. The treatments were randomly assigned to the unit plots, each measuring 3.05x1.525m (10' x5'). The daily average maximum and minimum temperature varied from 69.44⁰ to 98.60⁰F and 48.38 to 82.94⁰F respectively and the total rainfall was found to be 41.86 cm during the period of the experiment. The cultivar of onion used in this experiment was Faridpur vatti. The onion bulbs of nearly uniform size were planted on 13th and 23rd October, and 3rd and the 13th November in accordance with single row system of planting allowing spacing of 30.48 cm from row to row and 15.24 cm from bulb to bulb.
