Abstract

This study was carried out at the Experimental Farm of Environmental Agricultural Sciences Faculty, North Sinai Governorate, Arish University during 2020.  In order to study the response of four alfalfa varieties productivity (New Valley (NV), Siwa-1, Ismailia-1, Ramah1-1) to different planting distances (25, 50, 75 cm) among hills in sandy soil using growth criteria of alfalfa (Medicago sativa L.). Factorial experiment with randomized complete block design with three replicates was used. In the first Cut (1st cut), planting Swia variety by 25 cm among hills recorded the highest plant height (73.05 cm). NV variety recorded the maximum number of branches/plant (20.88). The interaction between varieties and hill planting distances on plant height revealed that the NV variety planted with 75 cm among hills recorded the highest number of branches/plant (23.01) in 1st cut. Varieties showed significant effect on fresh weight. Ramah1 variety recorded the maximum fresh weight (4.17 ton per faddan) in cut1. The interaction between varieties and among hills planting distances on dry yield. Ramah1 variety sown in 25 cm among hills recorded the highest dry weight (2.17 ton per faddan) in 1st cut. The highest plant height was recorded with 25 cm (80.52 cm) in the Fourth cut (4th cut). Ramah1 variety planted in 25 cm among hills recorded the highest plant height (92.22 cm) in 4th Cut. Finally, results concluded that planted Ramah1 variety with on – line distances of 25 cm among hills gave the highest forage productivity in sandy soil.
