“…Also agreed with the results of this study, Rezaei-Chianeh et al [32] showed reduction in the yield of faba bean under intercropping system. This experimental result is supported by Teshome et al [34] revealed that the maximum grain yield was obtained from sole cropping of soybean than intercropping in maizesoybean intercropping. Mean grain yield of common bean in the intercrop systems was significantly lower than the sole crop yield of common bean.…”

“…Maize (Zea mays L.) and common bean (Phaseolus vulgaris L.) are important food and cash crops cultivated for subsistence on smallholder farms in many parts of the world, including Sub-Saharan Africa. It is originated in Central America and was introduced to Ethiopia during the 1600s to 1700s [34]. In Ethiopia maize is one of the most important cereal crops grown in the country.…”

Maize is among the most important cereal crops in Ethiopia. Intercropping results in high overall system productivity on a given piece of land due to efficient use of the available plant growth resources. Field experiment was conducted to were to evaluate and select the cropping systems and best performing common bean varieties in intercropping with maize at jejebicho research station for higher productivity and profitability in southern parts of Ethiopia, under Wondo genet Agricultural Research Center at Sankura wereda, Jejebicho research station in 2019/20 cropping season. Three varieties of common bean (Deme, KAT-B1 and Awash-2) and were intercropped with two maize varieties (Limu and Shone). The three common bean varieties and two maize varieties were included as a sole for comparison. Randomized complete block design in factorial with three replications was used. Aboveground biomass, days to tasseling, hundred kernel weight, grain yield and harvest index of maize were significantly affected by varieties of common bean, cropping system was also significantly affected leaf area, leaf index, days to tasseling, days to physiological maturity and grain yield of maize but their interaction effect were non significantly affected. Days to tasseling of maize were delayed (81.50 days) and hastened (74.23 days) by variety Awash-2 and Deme, respectively as compared to KAT-B1. The wider leaf area (910.20cm 2 ) was measured from intercropped maize than sole and the larger leaf area index (3.79) was also recorded from intercropped maize than sole one. Days to tasseling of maize were delayed (80.80 days) at sole cropped of maize. The longer days to physiological maturity (143.84 days) of maize was taken from sole cropping of maize. The highest grain yield (7.60 ton/ha) of maize was taken from Shone intercropped with Awash-2 as compared to varieties. In cropping system, the maximum grain yield (7.12 ton/ha) of maize was obtained from intercropped of it. Plant height, branch number per plant, number of seed per pod, number of pod per plant, days to physiological maturity, aboveground biomass, hundred kernel weight, grain yield and harvest index of common bean. The longest plant (132.13cm) was measured from Deme intercropped with Limu. The highest (5.17) number of branches was counted at Deme intercropped with Limu. The highest number of pods per plant and number of seed per pod (10.92 and 4.63) was counted at Deme intercropped with Limu and Limu with Awash-2 respectively. The highest grain yield (22.38 ton/ha) was obtained when Shone intercropped with Deme. The highest partial land equivalent ratio (LER) of maize and common bean non significantly affected by varieties of both. Monitory advantage index was also non significantly affected. However, the highest value of monetary advantage index (105,359 ETB ha -1 ) was obtained at Shone intercropped with Deme. Therefore, any of the two (Limu or Shone) maize varieties could be recommended for intercropping with Deme of common bean variety.

“…Getachew(2007) also reported that higher harvest index was from intercropped maize with potato than sole cropped maize. In contrary to this, Gutu et al(2015) reported sole maize cropping system gave higher harvest index (0.39) than intercropped maize and soybean (0.37). Plant population: Different authors reported highest HIs obtained at high plant population densities.…”

“…Kerby et al (1990) pointed out that high plant density in cotton resulted more dry matter leaves and stems relative to fruit and thereafter low harvest index (HI). The higher number of HI (38.11%) was obtained from 25% (83, 333 plants /ha) soybean population than 50% and 75% soy bean populations (Gutu et al, 2015). Nutrients: Application of potassium (K) at the highest rate (90 kg ha -1 ) increased Harvest index (0.39) due higher K level was attributed to the more dry matter partitioning into the reproductive parts (ears) of maize (Amanullah et al,2015).…”

Harvest index (HI) is a measure of success in partitioning assimilated photosynthate. An improvement of crop harvest index means an increase in the economic portion of the crops in certain level. HI is a novel trait which contributed significant role in improvement of crop productivity which could solve the problem of food supplies for the rapidly increasing population. The objective of this paper was to review the role and progress of HI in improving crop productivity. Although crop HI influenced by both environmental and genetic factors, the progress improvement of HI and yield through crop management technique and breeding method strategy is an anticipative. In addition, the knowledge of genetic mode of expression of HI provides information for breeder to determine next breeding method.

“…Characteristics, such as number of seeds per pod and 100 seed weight, are mostly influenced by genetic factors [38]. Similarly, Solomon et al [39]; and Teshome et al [40], reported that number of seeds per pod was significantly not different due to the main effects of soybean varieties, plant densities and cropping system. In contrast, Mohammed & Tessema [41], reported significant effect of varieties on number of seeds per pod of soybean varieties regardless of row spacing and interaction of variety and row spacing.…”

Soybean is an important crop in the tropical, hot sub-moist agro-ecological zone of western Ethiopia. However, the yield of the crop is limited due to lack of appropriate plant density for the varieties. Therefore, the experiment was conducted to determine the effect inter row spacing on growth, yield components and yield of soybean varieties during 2016 cropping season in Dale Sedi District, western Ethiopia. Four inter row spacing (30, 40, 50 and 60cm) were evaluated on three soybean varieties (Nyala, Wello and Dhidhessa). The experimental design was randomized complete block design in factorial arrangement with three replications. Highly significant differences were obtained on days to 50% flowering, days to 90% physiological maturity, plant height and hundred grains weight (g) due to the main effect of the variety. Variety Nyala was earlier in attaining flowering (57.12 days), physiological maturity (115.6 days), variey Wello was the longest (84.70cm) and variety Nyala gave higher hundred grain weight (19.91g) than varieties Wello and Dhidhessa. The interaction effect of variety and inter row spacing were highly significant on number of primary branches, on crop stand count percentage at harvest, grain yield and harvest index, number of pods per plant, grain yield and harvest, where the highest numbers of primary branches per plant (4.57) and highest number pods per plant (49.83) were recorded for variety Wello at 60 cm, inter row spacing and the highest crop stand count percentage(99.77), the highest grain yield(3805kgha-1) and the highest harvest index (52.40%) were recorded from variety Nyala at 40 cm, inter row spacing. However, this tentative generalization based one season at one location requires further studies over years and locations to give a valid recommendation.
