“…The highest biomass water use efficiency was observed from double cropping (maize then bean) (31 kg mm -1 ) followed by relay cropping (19 kg mm -1 ) (Table 8). This is in line with the higher water use efficiency of multiple cropping than mono-cropping due to soil cover by the crop during the vegetative stage (Greenland and Lal, 1977;Siddoway and Barnett, 1976). The least WUE of biomass was obtained from double cropping (maize after bean) (9 kg mm -1 ).…”

Cereal crops especially maize production in Ethiopian Central Rift Valley is affected by biotic and abiotic production. This study was conducted for two seasons (2015-2016) and the best cropping system was identified using Randomized Complete Block Design with three replications. The experiment had six treatments (1) Continuous mono-cropping under conventional practice (CN), (2) continuous mono cropping under conservation agriculture (CA) (3) relay cropping (CA) with double bean planting within a season (maize bean inter-cropping: second round bean planting was conducted after immediate harvesting of the first bean), (4) Double cropping (CA) (maize bean inter cropping after sole lablab), (5) Double cropping (CA) (maize after bean) and (6) Double cropping (CA) (bean after maize). In 2016, the highest maize biomass yield and maximum water use efficiency were obtained from double cropping bean after maize with value of 16050 kg/ha and 31 kg mm -1 , respectively. Maize-bean relay cropping outperformed the sole maize under CA and CN by 182 and 138% for maize grain yield. Water use efficiency of double cropping (maize after bean) and relay cropping was higher than double cropping (bean after maize) by 366 and 197% in 2015 for maize grain yield. For biomass, relay cropping under CA and sole maize under CN had similar water use efficiency of 18 kg mm-1 . The CA practice with diverse crops planted together: double inter-cropping at different time (relay cropping) and double cropping under CA are good options for using the residual soil moisture and to sustainably improve crop productivity.

“…It is increasingly clear, however, that intercropping affords real, intrinsic advantages which may serve not only the isolated subsis tence farmer but the contemporary operator as well. I will not discuss at length the potential auxiliary advantages of intercropping on pest control (Barducci, 1972;Litsinger and Moody, 1976;Altieri et al, 1978), on soil erosion (Siddoway and Barnett, 1976) or on energy use efficiency (Norman, 1974;Heichel, 1976). I will concentrate, rather, on the evi dence for transgressive yielding by bean-maize intercrops and on the physiological bases which support it.…”

Figure kl. Total leaf area index in Type II and Type IV 2kS intercrops and in maize monocrops at 40,000 and at 55,000 plants per hectare * * * Beans and maize are staple food crops in many parts of Latin America, where they are predominantly produced in intercropped systems. It is common 1 y observed that bean yields are reduced by the presence of the maize, although the maize itself is little affected. The objective of my research was to investigate the physiological bases for the depressive influence of the maize on bean yields, in the first experiment, bean growth and yield responses were quantified and compared in monoculture and in association with maize. I hypothesized that maize affected bean growth by competing for resources, in space and over time. These hypotheses were tested in the remaining three seasons.
