“…Furthermore, the faba bean plant height increased within the sole plot. This is in agreement with the report of Getachew Agegnehu et al, 2006, which reported sole height of teff were the shortest in the sole plot than the mixtures in a tropical highland environment of Ethiopia.…”

Intercropping is the growing of two (or more) crops together on the same piece of land and often possess an advantage in terms of more yield and less use of plot of land compared to sole cropping. Some crop varieties may not fix environmental nitrogen hence they need application of more chemical fertilizers. Thus, intercropping may be chosen to alleviate a particular limitation of soil nitrogen resources. In this study, effect of intercropping systems of feba bean and wheat on yield of wheat in Ambo area, West Shoa, Ethiopia have been investigated. Experiments were conducted at Guder and Ginchi. The experiment was laid out in a randomized complete block designs (RCBD) with three replications. The treatments were sole wheat, sole faba bean, mix and alternate cropping systems. Results of the investigation showed that the highest wheat yield at Guder was 1420.8 Kg ha-1 and Ginchi was 1185.8 Kg ha-1 was obtained when wheat was intercropped alternatively with faba bean. Similarly, mix intercropped possesses significant wheat yield 1174 Kg ha-1) and 1013.3 Kg ha-1 at Guder and Ginchi sites, respectively. But the lowest yield was obtained from sole wheat at Ginchi (790 Kg ha-1) and Guder (1061 Kg ha-1) sites. At the two sites, the land equivalent ratio (LER>2) signify the tested cropping system approach is very much useful as it increase the yield on mix and alternate intercropped systems than the sole cropping.

“…Achieving sustainable supplies of teff flour for immigrant communities, industries (health and baby food), and local residents requires producing the crop locally rather than obtaining it by the less reliable imports (6). Teff is a potential rotation crop in certain environments where rotational crops (1) and late summer feed are limited (35).…”

Nitrogen and Phosphorus Requirements of Teff Grown Under Dryland Production System

et al. 2012

Nitrogen and phosphorus are key limiting nutrients in teff [Eragrostis tef (Zucc.) Trotter] production. The crop is particularly sensitive to N fertilization, and as a result forage and grain yields are influenced. We conducted four site‐year studies to determine N and P requirement of teff grown under a dryland production system. Studies were located in central Oklahoma. Treatments included nine N and P combinations. Commonly grown varieties ‘Quick‐E’ and ‘Tiffany’ were used in 2009 and 2010, respectively. Experiments were arranged in a randomized complete block design with three replications. Data were subject to statistical analysis using Statistical Analysis Software (SAS). Analysis of variance (ANOVA), orthogonal polynomial or paired contrasts and non‐linear regressions were used to determine the effect of treatments on teff forage and grain yields and quality. Results showed that for central Oklahoma, optimum fertilizer N rate was 67 kg/ha which corresponded with a 1.1 Mg/ha yield goal. Forage crude protein increased with N rate. In addition, N and P influenced some teff mineral and forage quality parameters such as Ca, Fe, acid detergent fiber, and crude protein. Recommendations provided here will serve as a benchmark for N and P fertility guidelines for producers in Oklahoma and semi‐arid regions who want to grow teff in a niche market.

“…In addition, intercropping ensures (i) availability of balanced diet to the farmers/locals, (ii) reduces the risks of crop failure due to adverse effects of pests/climate, (iii) lesser manure inputs and sustainability of soil nitrogen resources, (iv) improved use of scarce resources, (v) least soil erosion by providing continuous cover and (vi) also likely increase yield stability, thus providing improved returns (Willey 1979, Jensen 1996, Anil et al 1998， Dapaah et al 2003, Agegnehu et al 2006a, Langat et al 2006). In Himalaya, major inter crop combinations traditionally practiced include cereals with millets, millets with legumes, and legumes with legumes (Maikhuri et al 1997, Singh et al 1997, Nautiyal et al 2002.…”

Traditional agrodiversity management: A case study of central himalayan village ecosystem

et al. 2011

Environmental, biological, socio-cultural and economic status variation existing in the Central Himalaya have led to the evolution of diverse and unique traditional agroecosystems, crop species and livestock, which facilitate the traditional mountain farming societies to sustain themselves. Indigenous agroecosystems are highly site specific and differ from place to place, as they have evolved along divergent lines. For maintenance of traditional agrodiversity management the farmers of the Central Himalaya have evolved various types of crop rotations in consonance with the varied environmental conditions and agronomic requirements. In irrigated flat lands two crops are harvested in a year with negligible fallow period but in rainfed conditions if a cropping sequence is presumed to be starting after winter fallow phase then four major cropping seasons can be identified namely first kharif season (first crop season), first rabi season (second crop season), second kharif season (third crop season) and second rabi season (fourth crop season). Highest crop diversity is present in kharif season in comparison to rabi season. Traditionally the fields are left fallow after harvest of the second kharif season crop. Important characteristics of agrodiversity management are the use of bullocks for draught power, human energy as labour, crop residues as animal feed and animal waste mixed with forest litter as organic input to restore soil fertility levels. Women provide most of the human labour except for ploughing and threshing grain. The present study deals with assessment of traditional agrodiversity management such as (i) crop diversity, (ii) realized yield under the traditional practices and (iii) assess the differences of realized yields under sole and mixed cropping systems. It indicated that crop rotation is an important feature of the Central Himalayan village ecosystem which helps to continue the diversity of species grown, as are the distribution of crops in the growing period and the management of soil fertility. The cropping diversity existing and the sequences practiced by the traditional farmers seems to have achieved high degree of specialization and thus even when the yield/biomass variations are about 60%, the farmers continue to practice these sequences as they need to maintain diversity and synergistic relationships of crops in addition to manage the food and labour requirements for crop husbandry. Crop yields are generally higher in irrigated systems than rainfed systems and in sole cropping as compared with mixed cropping. However, gross biological and economic yields are higher in mixed cropping than sole cropping systems.
