Effect of different rates and plant densities on qualitative and quantitative yield of mixed Lucerne-millet forage in an alley cropping system

This experiment was conducted to find the effect of different ratios of plant on the quantitative and qualitative yield - the mixture of alfalfa and millet in the condition of Alley cropping system in two crop seasons of years 1387-1388 and 1388-1389 in experimental field of Agriculture college¡ Karaj Branch¡ located in Mahdasht . In this experiment¡ millet and alfalfa were planted in the method of mixed cropping and with different ratios of seed in the form of mixed cropping and pure culture (solid planting) in between the trees¡ simultaneously. The treatment were: five rate of planting(m1Pure culture of alfalfa¡ m The mixed ratio 75% alfalfa and 25% of millet¡ m3 The ratio 50% : 50% of alfalfa and millet respectively¡ m4 The ratio 25% : 75% of alfalfa and millet¡ m5 Pure culture of millet) and two calculated densities (d1 30 kg alfalfa and 40 kg millet¡ d2 45 kg alfalfa and 60 kg millet).The rate of used seed was calculated for the mentioned ratios: 25%¡ 50% and 75%. The cropping was done in the Spring and in the form of mixed cropping of alfalfa and millet in between the trees. The measured characters included the percentage of: Fresh yield¡ Dry yield¡ Sugars soluble in water¡Ash¡ Cell wall and Protein yield. The results corresponding to the analysis of variance showed that : protein yield of alfalfawas54/17(kg/ha) more than protein yield in millet¡ The percentage of soluble sugar in water of alfalfa was more than millet about (1/84%). Also millet had the highest percentage of total Ash than alfalfa about 1/05%)¡The result obtained from comparing the different ratios of planting showed that the percentage of total Ash in pure culture of millet were highest percentage. The results showed the millet had the most fresh weight and also pure culture of alfalfa had the least fresh weight between the others ratio of planting.
