- Abstract
The present investigation was conducted at Kafr Al-hamam Agricultural Research Station, Agric. Research Center (ARC) and at the laboratory of the Seed Technology Research Department, Field Crops Research Institute, ARC, Giza, Egypt during the two successive seasons of 2018/2019 and 2019/2020. The study aimed to find out the effects of three last cut dates (15th March, 15th April, and 15th May) and three fertiliser systems (15kgN fad-1 and 15kgN fad-1+ foliar spray of micronutrients) on forage yield, seed yield and its components, seed quality, and economic evaluation of Egyptian clover (Helali cultivar). A randomised complete block split-plot design with three replications was used in each season. The results of combined data from the two seasons of the investigation indicated that delaying the last cut on May 15th significantly increased seasonal fresh and dry forage yields (44.00 and 8.63 tonnes fad.-1) respectively, compared to the other cut dates. While the last cut on April 15th gave the highest value for seed yield and its components, as well as improving most quality traits. The treatments of 15kg N fad.-1+foliar spray of micronutrients showed superiority compared to the other treatments. The interaction between the last cut and the fertiliser system had significant effects on most studied traits of the Egyptian clover crop. It could be concluded that the time of last cut on April 15 is indicated as the optimal time to last cut with applying 15 kg N fad-1. +foliar spray of micronutrient for enhanced seed production and good quality with enough quantity of forage yield and the improvement of maximum income per unit area with Egyptian clover for the dual purpose. In particular, the seed can only be produced as part of the forage yield calculation. Also, noting that high-quality seed enables farmers to obtain crop stands with an economical planting rate, high emergence, vigorous seedling establishment, uniformity in crop stand, uniformity in ripening, faster growth, and high resistance to biotic and abiotic factors.
