Abstract

A field experiment was conducted at the Agricultural Experiments and Researches Station, CairoUniversity, Giza, Egypt from 2008 to 2011 to study the influence of cutting treatment before seed production and plant densities on seed yield of two alfalfa genotypes (Laboon and El-wadi El-Gadid). In General, El-wadi El-Gadid surpassed Laboon in seed yield/feddan. Cutting genotypes twice before seed production recorded the highest seed yield and its components. Seed yield was significantly increased with increasing plant density from 8.400 to 134.400 plant/fed. The interaction between harvesting treatment and genotypes was significant for seed yield in 2010 and 2011 years. El-wadi El-Gadid produced the highest seed yield when cut twice. It also recorded the heaviest seed yield under plant density of 134.400 plant/fed. The second order interaction (El-wadi El-Gadid × cutting twice ×134.400 plant/fed) gave the highest seed yield in both years. Highly significant and negative correlation was observed between seed yield and number of pods /plant (-0.32) and seed index (-0.34).
