Abstract

A lab experiment was conducted under natural conditions in Higher and Moderate Institute of Agricultural Technology Labs, Algheran, Libya to study storage period, package, type and their interactions effects on germination, seedling characters, infestation percent, and biochemical components of Sidi Almasry barley grains. Split-plot in completely randomized design in three replications was used. The most important results could be summarized as follows:
Increasing storage period up to six months decreased 1000-grains weight, falling number, seedling and radical length, however grain-moisture, protein, fat and ash contents and infestation percentage with Fusarium were significantly increased.
On the other hand, high density polyethylene bags significantly decreased 1000-grain weight (39.47%), germination percent (83.66%), seedling and radical length (6.09 and 7.99 cm), falling number (384.50) and grain protein content (11.97 %), however, this type of package increased grain moisture content (12.47%) and Fusarium infestation percent (8.47%).
Interaction between the two factors indicated that barley grains stored for six months in high density polyethylene significantly decreased 1000-grain weight, germination percent, falling number and increased Fusarium infestation percent, grain moisture and protein contents. Conversely, storage barley grains in jute bags for six months can alleviate the adverse effects on warehouse and other studied package types.
