“…More PAR interception by different intercropping systems has been reported (Chand, 1997;Ghanbari-Bonjar, 2000;Midmore et al, 1988). High light interception by intercrops caused higher shading and, therefore, lowers soil temperature, which agrees with the finding of Harris and Natarajan (1987) who suggested that the micro climate within the canopy tercropping (I 1 ), within-row intercropping (I 2 ) and mixed intercropping (I 3 ).…”

A field experiment was carried out in Ramhormoz, Iran during the 2008-2009 growing season to investigate the effects of different planting pattern of intercropping on environmental resource consumption and weed biomass. A randomized complete block design (RCBD) with three replications was employed to compare the treatments. Treatments included maize sole crop (M), cow pea sole crop (C), within row intercropping (I 1 ), row intercropping (I 2 ) and mix cropping (I 3 ). The density of intercropping was according to replacement design (one maize replaced by three cow pea plants). The results showed that environmental resource consumption was significantly (P≤0.05) affected by cropping system, where PAR interception, moisture and nutrients uptake were higher in intercropping systems compared to sole crop systems. Regarding to weed control, intercrops were more effective than sole crops and it was related to lower availability of environmental resources for weeds in intercropping systems.

“…Use of different resource pools by the component crops represents the most common example of complementarity. The temporal use of irradiance within intercrops of contrasting development and phenology is a prime example illustrating the more efficient use of naturally available resources by intercrops than by each crop (Midmore et al 1988a).…”

An on-farm experiment was conducted in the dry season of 2012/2013under irrigation at Jigna rural village of Dera District, South Gonder Zone/Ethiopia. The experiment was conducted to assess the biological benefits of intercropping maize with fenugreek, field pea and haricot bean. A field have a total of 7 treatments, namely three intercropping of fenugreek, field pea and haricot bean with maize and their four sole cropping, were laid out in randomized complete block design (RCBD) with three replications. Gross plot size of each treatment was 3m × 2.7m (8.1m 2), but net plot size varied up on the crop types. Spacing between adjacent replications and plots was 1.5m and 1.0m, respectively. Fenugreek, field pea and haricot bean as sole crops were planted at inter-row and intra-row spacing of 20cm × 5cm, 20cm × 5cm and 40cm × 10cm, respectively. In both intercropping and sole cropping maize was planted at 75cm× 30cm inter-and intra-row spacing, while fenugreek, field pea and haricot bean were intercropped in the middle of two maize rows at their recommended intra-spacing. Varieties used for the present study were BH-540 maize hybrid, "Challa" fenugreek, "Burkitu" field pea and "Awash Melkassa" haricot bean. Data of phenological, vegetative growth and, yield related crop parameters were timely collected following their respective standard methods and procedures, and further subjected to analysis of variance (ANOVA) using SAS version 9.2. Whenever the ANOVA result showed significant difference among treatments for a parameter mean separation was further done using Duncan's New Multiple Range Test (DNMRT). Intercropping didn't show any significant effect statistically (p<0.05) on phenological, vegetative growth and yield related parameters of the component crops. However, concerning biomass of fenugreek, field pea and haricot bean, the analysis of variance showed that there has significant difference (p≤0.05) between intercropping and sole cropping. On the contrary, intercropped field pea produced higher pod per plant, plant height and seed per pod than that of sole field pea. Intercropped Haricot bean was also produced slightly higher plant height, seed per pod and thousand grain weights than its sole crops. Therefore, in the present study area during dry season under irrigation, maize intercropping with haricot bean and field pea was more advantageous than their respective sole crops.

“…Differences in vertical arrangement of foliage and canopy architecture of intercrop components, may lead to more PAR (photo-synthetically active radiation) interception by intercropping compared with sole crops (Keating and Carberry 1993). More PAR interception by different intercropping systems has been reported (Chand 1997, Midmore et al 1988. PAR interception seems to play a relatively important role in determining total intercrop productivity.…”

Multiple cropping is an agriculture system long adopted by marginalized small holder farmers especially in hills and mountains. This practice was a meant to enhance farm productivity when farming area is limited. Here, in this paper, a brief review on the benefits of multiple cropping is presented focusing on the practices adopted by marginalized farmers, in general. In multiple cropping, it is generally argued that the practice favors an efficient utilization of resources like air, water, light, space, and nutrients by companion crops in both temporal and spatial dimensions due to their differential growth habits and seasonality. Multiple cropping could be one of the viable alternatives to cope uncertainties and changes, where food and nutritional uncertainty looming large. The ultimate outcome of multiple cropping could be visualized in adverse or harsh environment for increase agriculture production, livelihood and income. Various food products are obtained through multiple cropping. Land equivalent ratio (LER), relative yield total (RYT) and income equivalent ratio (IER) can be increased with mixed/intercropping systems. Multiple cropping helps in getting more than one crop simultaneously, so even if the selling price of one commodity is less, the other might compensate. In the tropics, smallholder farms, which produce over 60% of the food resources of developing nations from intercropping of cereals with many crops mostly legumes, had been the field of much investigation because of synergistic effects of diversifying food production and household cash incomes in these systems. This clearly implies the importance of multiple cropping for small farmers who constitute majority in the developing countries.
