Abstract:
Multiple cropping is defined as the intensification of cropping in time and space leading to
growing two or more crops on the same fieldin a year {Paudel, 2016}.Multiple cropping is not a
new form of agricultural technology, instead is an ancient means ofintensive farming. Multiple
cropping is a farming practice involving two or more crop species or genotypes growing
together and coexisting for a certain period.Multiple cropping has been practiced in many parts
of the world as a way to maximize land productivity in a smallarea in growing season by
improving the intensity of land and labor use for better profit and stabilizing farm income (Joshi
2007).Multiple cropping becomes one unique route to delivering sustainable intensification.Nine
treatments (sole sorghum, sole haricot bean, sole mung bean, sorghum +haricot bean (1:3),
sorghum +mung bean (1:2 row), sorghum +haricot bean (1:5 row), sorghum +mung bean (1:4
row), sorghum +haricot bean (2:3 row) and sorghum +mung bean (2:2 row) were arranged in
Randomized Complete Block Design (RCBD) with three replications.All the data for both
dependent and independent variables were collected from central Gondar agricultural research
institute and West Amhara meteorological service center.The analysis of variance results
indicated that most of yield and yield components of sorghumwith haricot bean and mung bean
were significantly affected by the main effect of haricot bean and mung bean.Analysis of
variance showed that grain yield of sorghum, biomass and 1000 seed weight of sorghum haricot
bean and mung bean was significance difference.Land Equivalent Ratio (LER) was more than
unity in all cases. The highest LER,1.79 was obtained from sorghum with haricot bean (1:3
rows).Potential multiple cropping index the fundamental characteristics of the changes in the
potential multiple cropping system were that the single cropping area decreasing and the triple
cropping area increased. Moreover, the PMCI showed that an increasing trend
