Abstract
Two field experiments were performed at Mariut Research Station, Desert Research Center (DRC) during 1993 and 1994 growing seasons to study the effect of three cropping patterns i.e. alfalfa pure stand, buffel grass pure stand and alfalfa/buffel grass mixture; three organic manure rates viz., 10, 20 and 30 m3/fed., in addition to two rates of sulfur i.e. 0.4 and 0.8 ton/fed. on some growth parameters and forage yield. The experiment was arranged in a completely randomized block design with four replications. The results can be summarized as follows:
1. Growing buffel grass with alfalfa decreased plant height and leaf area of buffel grass comparing with sole crop while the reverse was true for alfalfa when mixed with buffel grass. Number of branches/plant for alfalfa were increased by mix cropping than sole cropping. Opposite results were obtained for leaf/stem ratio. Alfalfa-buffel grass mixture had a superiority of fresh or dry yield as well as accumulated yield over that of sole cropping.
2. Increasing organic manure rates from 10 to 30 m3/fed had no significant effect on plant height and leaf/stem ratio of buffel grass, meanwhile leaf area was significantly increased at 2 cuts out of six.
Most of alfalfa growth characters were increased according to increasing manure rates. Moreover, dry yield as well as accumulated yields for buffel grass, alfalfa and their mixture were increased due to increase farmyard manure level.
3. Raising sulfur rates from 0.4 to 0.8 ton/fed had no significant effect on growth parameters of either buffel grass or alfalfa at most cuts taken with few exceptions. In addition, no significant responses were detected for forage yield due to sulfur application.
4. Interaction between the main factors had significant effects on some growth and yield characters at some cuts of both seasons.
