“…However, during the establishment year, alfalfa forage yield was positively associated with seeding rate and yield was less consistent in subsequent years because of stand losses (Volence et al, 1987;Boulton et al, 1990). Furthermore, Sarraj (1987) pointed out that the alfalfa plant population was slightly affected by seeding rate.…”

Purpose: A field experiment was conducted at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum at Shambat during the period November 2001 to June 2002 to investigate the effect of seeding rates on growth and forage fresh and dry matter yields of two alfalfa (Medicago sativa L.) cultivars. Design/methodology/approach: The treatments comprised four seeding rates viz; 10, 15, 20 and 25 kg ha-1 and two alfalfa cultivars (the local cultivar Hegazi and the introduced cultivar Siriver). The treatments were randomly assigned in a split plot design with four replicates. Parameters measured: plant density, plant height, leaf-to-stem ratio, leaf area index (LAI) and forage fresh and dry matter yields. Findings: The results illustrated that a seeding rate of 25 kg ha-1 increased plant density, leaf area index and forage dry matter yield. A seeding rate of 15 kg ha-1 increased plant height and was superior over other seeding rates in forage fresh yield, whereas 20 kg ha-1 increased leaf-to-stem ratio. The local cultivar Hegazi tended to be superior over the introduced cultivar Siriver in plant height and forage fresh anddry matter yields. In contrast, the introduced cultivar was superior over the local one in plant density, number of leaves per plant, leaf area index and leaf-to-stem ratio.

Persistence is a critical component of alfalfa (Medicago sativa L.) crop yield. Our objective was to determine the effect of seeding rate on alfalfa persistence, yield, and yield components and how they evolved over time in irrigated areas with long growing seasons. Two alfalfa cultivars were seeded at four seeding rates (10, 20, 30, and 40 kg ha−1), in three consecutive experiments, and evaluated over a 3‐yr period to provide total data for nine location years. Seed rates of 10 kg ha−1 [8.75 kg ha−1 of pure live seed (PLS)] produced total 3‐yr dry matter (DM) yields of between 50.8 and 58.9 Mg ha−1. Seed rates only affected total 3‐yr DM yields in one of the three experiments. The mean number of shoots per m−2 was 488 and this was not affected by seed rates. The effect of seed density on mean shoot weight depended on the experiment. The annual average crude protein (CP) concentration varied from 159 g kg−1 to 224 g kg−1 while the leaf to stem ratio varied from 0.87 to 1.17. The results suggest that CP and leaf to stem ratios (LSR) were either little influenced or not influenced by seed density. The DM yields and yield components indicate that 8.75 kg ha−1 of PLS could be sufficient to ensure adequate DM production. Results also suggest that in a Mediterranean climate in which sprinkler irrigation is applied, there is little justification for high seeding rates under good establishment conditions.
