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.

A field experiment was carried out during 2020/ 2021 winter season in a private farm at Al-Maamorah district, El-Ghafara, Tripoli, Libya to evaluate four planting dates (1 st and mid November and 1 st and mid December) and four seeding rates (80, 100, 120 and 140 kg ha -1 ) on growth, grain yield, yield attributes and grain protein content of Sidi Almsry durum wheat variety. Randomized complete block design in split plot arrangement in three replications was used, where the four sowing dates were randomly allocated in the main plots and the four seeding rates were randomly distributed within each main plot. Obtained results indicated that planting the studied variety at mid November produced the tallest plants, highest LAI, number of tillers and spikes m -2 , number of grains spike -1 , grain yield, H.I. and heaviest 1000-grain weight. However, 140 kg seeds ha -1 produced the tallest plants, highest LAI, number of tillers and spikes m -2 , lodging percentage and grain protein content. Meanwhile, planting Sidi Almsry variety at mid November with 100 kg seeds ha -1 produced maximum grain yield, H.I and 1000-grain weight, while 140 kg seeds ha -1 at mid November produced the tallest plants and highest LAI, number of tillers and spikes m -2 . The highest grain protein content resulted from sowing at mid December with 140 kg seeds ha -1 .

This experiment was conducted at Grower Farm in Al-Maamorah district, El-Ghafara, Tripoli, Libya, during 2020 summer season to study effect of four maize hybrids (SC 10, SC 176, TC 310 and TC 360)as main plots and three maize plant densities, i.e. 166667, 83333 and 55555 plants/ ha as sub plots in a split plot design with three replicates on silage yield and quality. Results showed that SC 10 had the tallest plants (183.03 and 210.93 cm) and stalk diameters (21.08 and 24.46 mm) at 55 and 90 DAS, leaf/ stem ratio (59.06%), number of ears/ plant (1.21) and total dry forage yield (17.059 t/ ha) at 90 DAS. However, single crosses studied were significantly surpassed in leaf area index, number of leaves/ plant and total dry forage yield at 55 DAS, besides protein yield. The highest plant density (166667 plants/ ha) produced maximum plant height and total dry forage yield at 55 and 90 DAS, maximum L.A.I. at 55 DAS. Conversely, the lowest plant density (55555 plants/ ha) produced thicker stalks and highest plant dry weight at 55 and 90 DAS and highest leaf/ stem ratio, protein yield and number of ears/ plant. Interaction between the two factors studied pointed out that sowing SC 10 at 166667 plants/ ha produced the tallest plants and highest total dry forage yield at 55 and 90 DAS, and LAI at 55 DAS. However, sowing the same hybrid at the lowest plant density showed thicker stalks at 55 and 90 DAS, number of leaves and ears/ plant.
