Effect of sulphur application in onion (Allium cepa L.)

An experiment was conducted to study the effect of sulphur application on growth, yield and quality of onion at Horticulture Farm of Institute of Agriculture, Visva-Bharati, Sriniketan. The treatments consisted of six incremental doses of sulphur application (10, 20, 30, 40, 50 and 60 kg ha-1) and no sulphur application (control, 0 kg S ha-1). Treatments were arranged in Randomized Block Design...

Screening of Local and Exotic Onion (allium Cepa L.) Cultivars for Seed Production Potentiality

Onion (Allium cepa L., 2n=16) is a cross-pollinated and biennial short type vegetable and most of the important spice as well as vegetable crops throughout the world. Bulb is the main edible portion of onion plant, which is a modified organ and constituted by the thickened fleshy leaf sheaths and stem plate (Purseglove, 1988). The leading onion producing countries of the world are China, India,...

Diversity and abundance of insect pollinators on Allium cepa L

Field experiment was conducted at CCS Haryana Agricultural University, Hisar during 2009-10 to investigate the diversity and abundance of insect pollinators on Allium cepa L. and correlate their incidence in relation to the abiotic environmental factors. Hymenopterans were found to be the most abundant (60%) followed by Lepidoptera, Diptera and Coleoptera. Variation in abundance was recorded ov...

Estimation of Genetic Diversity in Onion (Allium cepa L.)

The experiment was conducted at the field laboratory of the Department of Genetics and Plant Breeding, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur during November 2008 to March 2009 to estimate the genetic diversity of exotic and local onion. Ten genotypes of onion were evaluated for 16 characters in a randomized complete block design to study the genetic divergence throu...
