Abstract
This study was carried out during 2022/2023 season in Sof Al-Jin Farm in Bani Walid, Libya, to evaluate the effect of NPK and vermicompost on some vegetative growth and yield and yield components and chemical composition of barley cv. "Giza 132". This experiment consisted of seven treatments arranged in a Randomized complete Block Design (RCBD) design with three replicates for each treatment. The treatments were (Control, 100 % NPK RDF, V.C (vermicompost) 15 t/ ha, 100 % NPK RDF + V.C 15 t/ ha, 75 % NPK RDF + V.C 5 t/ ha, 50 % NPK RDF + V.C 7.5 t/ha, 25 % NPK RDF + V.C 10 t/ ha). Results showed that the treatment of 100% RDF+ V.C 15 t/ ha recorded the higher values of all vegetative growth characters, yield and yield components and chemical composition of barley cv. "Giza 132" e.g. plant height, dry matter accumulation (g/m2), spike length, number of spikes/ m2,number of grains/ spike, 1000-grains weights, grains yield (t/ha), biological yield (t/ha), harvest index (%), nitrogen, phosphorus, potassium and protein percentages, followed by V.C 15 t/ ha and 25 % RDF + V.C 10 t/ ha, as compared to control treatment which recorded the lower of plant height, dry matter accumulation (g/m2), spike length, number of spikes/ m2,number of grains/ spike, 1000-grains weights, grains yield (t/ha), biological yield (t/ha), harvest index (%), nitrogen, phosphorus, potassium and protein percentages under experimental condition. In conclusion: The explanation could be that adding a significant amount of vermicompost before planting improved the soil properties, which increased the flag leaf area of plants receiving enough light energy and converting it into dry matter, which increased the weight of grains.
