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...
متن کاملEstimation 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...
متن کاملNUTRIENT DIAGNOSIS ( CND ) OF ONION ( Allium cepa L . )
Nutritional constraints often restrict yields of crops in farmers’ fields. Plant nutrient status is currently diagnosed using empirically derived nutrient norms from arbitrarily defined high and low yielding subpopulations above a quantitative yield target. Generic models can assist Compositional Nutrient Diagnosis (CND) in providing a yield cutoff value between high-and lowyielding subpopulati...
متن کاملRisk Evaluation of Industrial Wastewater on Plants Using Onion (allium Cepa L.) Chromosome Aberration Assay
Rapid strides in industrialization coupled with incomplete sewage treatment system have led to indiscriminate discharge of potentially mutagenic wastewater into agricultural lands and water bodies. The response of Onion plant genetic material to the presence of potential cytotoxic and genotoxic substances in the environment was used to evaluate the toxicity of chemical effluent collected from a...
متن کاملIdentification of a glutathione S-transferase inhibitor in onion bulb (Allium cepa L.)
A glutathione S-transferase (GST, EC 2.5.1.18) inhibitor was isolated from the onion bulb by fractionation and purification using Sep-pak Vac C18 column, TLC and HPLC. Five partially purified onion bulb GSTs (GSTa and GSTb as minor GSTs, and GSTc, GSTd and GSTe as dominant GSTs) separated by DEAE column were used to detect the inhibitory substance in onion bulb extract. Among the three fraction...
