Abstract
A field experiment was conducted at the Demonstration Farm of the Faculty of Agriculture, University of Khartoum during the period November 2003 to July 2005 - study the effect of sowing methods, seeding rates and cutting management on growth, forage and seed yield of alfalfa (Medicago sativa L.). The treatments comprised two sowing methods which were sowing on flat and sowing on ridges and three seeding rates which were 7.1, 14.3 and 21.4 kg/ha and four cutting management which were no cutting, one cut, two cuts and three cuts. Parameters measured were plant density, plant height, forage yield, dry matter production, seed yield component, and final seed production. Results showed that sowing on ridges had a significant effect on plant density, number of racemes per plant and number of flowers per plant, whereas the sowing on flat had a significant effect on fresh weight, dry weight and plant height. Seed rate of 21.4 Kg / ha (S3) had a significant effect on plant density, fresh weight, dry weight, number of seeds per pod in the two seasons and on the thousand seed weight in the second season, while seed rate 14.3 kg/ha (S2) had a significant effect on number of pods per plant in the second season only. Seed rate of 7.1 kg/ha (S1) had a significant effect on number of seeds per pod in the first season, thousand seed weight in the first season, and total seed weight in the two seasons. Result also showed that cutting plants three times (C3) had a significant effect on plant density in the first season and fresh weight in the second season, while cutting once (C1) had a high significant effect on number of flowers per plant in the second season and on number of pods per plant in the first season. No cutting (C0) had a significant effect on number of seeds per pod in the second season and on total seed yield.
