“…Average yields of soybean strips MG III were 6, 13, and 11% lower than those in the monoculture, whereas in MG V yields were 2, 8, and 8% lower than those in the monocultures during C1, C2, and C3, respectively (Figure 4). Results are similar to those obtained by Pendleton et al [35], Lesoing and Francis,[20,21], West and Griffith, [15], Ghaffarzadeh et al [16], and Francis et al [27].…”

Crop growth rates (CGR), radiation interception (IPAR), yields, and their components were determined in two crops monocultures (using one corn and two soybean genotypes) and in intercropped "strips," during three growing seasons. Corn yield in the strips significantly increased in the three seasons (13-16%) as compared to that in the monocultures. This response was due to increased yield in corn plants of the border rows of the strips, which was highly correlated to an increased IPAR, allowing high CGR at critical crop stages. As a result, more dry matter was partitioned to grain and also an increased number of ears per plant were generated. Conversely, yields of soybeans in the strips were 2 to 11% lower than that in the monocultures, with variable significance depending on soybean cultivar and/or year. Grain number per unit area was the yield component most closely associated to yield variation in both crops. We believe that if yield components of this system are more closely identified, more appropriate genotypes will fit into strip intercropping, thus contributing to the spread of this technique and thus to the sustainability of actual massive monocultured agricultural systems.

“…Corn yield increased 13, 13, and 16% when cultivated with MG III soybean strip and 15, 15, and 16% with MG V soybean strip, during C1, C2, and C3, respectively (Figure 4). Results are similar to that obtained in USA [15,16], China [17], and Argentina, [18,19].…”

“…Li et al (1999) noted that interspecies root interactions between intercropped fava bean and maize played an important role in increasing yield and nitrogen and phosphorus acquisition within an intercropping system. Ghaffarzadeh et al (1994) found that strip intercropping led to a 20-24% greater maize yield and a 10-15% lower soybean yield in adjacent border rows in a maize/soybean intercropping system.…”

A 2-year study (2010)(2011) was carried out in order to evaluate the effects of bean and maize intercropping. The experiment tested five different cropping systems: sole cropping of each crop, as well as intercropping of maize/bean with the ratios of 1:3 (M 1 B 3 ), 2:2 (M 2 B 2 ) and 3:1 (M 3 B 1 ), each of which took place in the presence of two weed management systems (no weed control and weed eradication through manual removal), in a factorial experiment based on randomized complete block design using three replicates. Tests of homogeneity of variance for combined data over two years showed that data of both years could be analyzed together. The results showed that the effect of intercropping treatments on all measured traits in maize and bean were significantly different. A minimum land equivalent ratio (LER) for maize (0.78) was obtained for M 3 B 1 under conditions of no weed control, while the highest LER (1.03) was observed in M 3 B 1 under weed-free conditions. The highest (0.99) and lowest (0.70) LER values for beans were recorded for M 1 B 3 under weed-free conditions and M 3 B 1 under conditions of no weed control, respectively. M 1 B 3 under weed-free conditions showed the highest total LER (2.02), while M 3 B 1 under conditions of no weed control showed the lowest (1.48). Results of this study indicated that intercropping bean and maize can be an effective method to increase total productivity, and that the M 1 B 3 system was the best cropping system for high productivity.

“…Ghaffarzadeh et al [57] observed that the potential for stress could be increased when crops compete among themselves. Ghaffarzadeh et al [58] further intimated that competition for resources might develop because of root growth patterns and/or different resource demands, although they acknowledged that there is limited information available about light, water, and nutrient competition in regard to plant position.…”

Conservation Farming and Changing Climate: More Beneficial than Conventional Methods for Degraded Ugandan Soils

Abstract:The extent of land affected by degradation in Uganda ranges from 20% in relatively flat and vegetation-covered areas to 90% in the eastern and southwestern highlands. Land degradation has adversely affected smallholder agro-ecosystems including direct damage and loss of critical ecosystem services such as agricultural land/soil and biodiversity. This study evaluated the extent of bare grounds in Nakasongola, one of the districts in the Cattle Corridor of Uganda and the yield responses of maize (Zea mays) and common bean (Phaseolus vulgaris L.) to different tillage methods in the district. Bare ground was determined by a supervised multi-band satellite image classification using the Maximum Likelihood Classifier (MLC). Field trials on maize and bean grain yield responses to tillage practices used a randomized complete block design with three replications, evaluating conventional farmer practice (CFP); permanent planting basins (PPB); and rip lines, with or without fertilizer in maize and bean rotations. Bare ground coverage in the Nakasongola District was 187 km 2 (11%) of the 1741 km 2 of arable land due to extreme cases of soil compaction. All practices, whether conventional or the newly introduced conservation farming practices in combination with fertilizer increased bean and maize grain yields, albeit with minimal statistical significance in some cases. The newly introduced conservation farming tillage practices increased the bean grain yield relative to conventional practices by 41% in PPBs and 43% in rip lines. In maize, the newly introduced conservation farming tillage practices increased the grain yield by 78% on average, relative to conventional practices. Apparently, conservation farming tillage methods proved beneficial relative to conventional methods on degraded soils, with the short-term benefit of increasing land productivity leading to better harvests and food security.
