“…The allelochemicals like p-coumaric, p-hydroxybenzoic, vanillic, and syringic acids have been identified from the straw residues (Guenzi and McCalla, 1966). Likewise, in corn continuous sole cropping in monoculture results in decline in its yield due to release of allelochemicals from the decomposing residues Cruse, 1983, 1984;Turco et al, 1990;Crookston et al, 1991). Turco et al (1990) have pointed out that decomposing residues may even alter the microbial composition of the soil which may not be beneficial to the crop.…”

A number of crops exhibit allelopathic interactions that play a significant role in the complex environment of agroecosystems. Several studies have shown that allelopathic crops reduce growth, development and yield of other crops growing simultaneously or subsequently in the fields. Another aspect of interest regarding crop allelopathy is that allelochemicals may exhibit inhibitory effect on the same crop which is commonly called as crop autotoxicity. It is predominantly common in fields where sole cropping under reduced or no-tillage system is practiced. Though any crop part can be allelopathic, including even the pollens, but decomposing crop residues exhibit more influence on other plants. Furthermore, the extent of allelopathy by a crop plant varies with age, part and type of cultivar being used. Nowadays allelopathic crops are being used as an important tool in managing weeds and harmful pests under sustainable pest management programs. In this context several cover/smother and green manure crops with allelopathic

“…The numbers of cultivated bacteria and the diversity indexes such as the Margalef index, Shannon-Wiener index, and Simpson index from R-R-MV rotation were all higher than those of R-R-WF rotation, indicating more diverse endophytic bacteria, although there was no research on the effects of rotation on endophytic bacteria, reports on the influence of rotation on soil microbes have already existed. Turco et al [34] studied the effects of autochthonous bacteria in continuous corn and rotated corn-soybean on the growth of corn, indicating that continuous cropping leaded to increasing numbers of bacteria which suppressed the growth of corn while rotation gave birth to a lower percentage of such bacteria; Peters et al [24] found that rotation enhanced the antibiosis abilities of endophytic and rhizosphere bacteria (endo-and exoroot) against pathogenic fungi; community level physiological profiles indicated that rotation cropping systems tended to have higher overall microbial activity compared to continuous cropping systems [18,36]. According to random amplified polymorphic DNA analysis, rotation cropping of cucumbers showed higher soil microbial activity, microbial biomass, and Shannon-Weaver index than continuous cropping [36].…”

This study focuses on the effects of long-term rice rotated with milk vetch being as green manure on the composition of bacteria in rice roots. The endophytic bacterial communities in rice roots of the rice-rice-milk vetch (R-R-MV) and the rice-rice-winter fallow (R-R-WF) crop rotations with a 28-year research history were investigated using combined culture-dependent and culture-independent methods. It was found that the endophytic bacterial population in rice roots with the green manure was significantly higher than that of without it. There were 169 and 77 strains of endophytic bacteria that were isolated from rice roots of the R-R-MV and the R-R-WF, respectively. The 16S rRNA gene analysis shows that the 77 R-R-WF bacteria belong to 15 species of 14 genera while the other 169 R-R-MV bacteria belong to 21 species of 19 genera, in which Herbaspirillum and Cedecea were two mutually dominant populations and Burkholderia, Pseudomonas, Sphingomonas, and Pantoea accounted for large proportions of the endophytic bacteria in rice roots through R-R-MV rotation. The analysis of 16S rDNA clone libraries showed that the Shannon-Weaver diversity index of endophytic bacteria in R-R-MV approximates that in R-R-WF rotation, whereas the richness indexes of Chao 1 and ACE in R-R-MV rotation system were significantly higher than those in R-R-WF rotation. The diversity of endophytic bacteria was richer in R-R-MV. Both the culture-dependent and the cultureindependent method revealed significant effect of long-term different tillage systems on the microbial community.

“…The effects may be attributed to a larger residual soil N from the former system compared to the latter (Bagayoko et al, 1996). These effects obviously derive from the larger amounts of above-and belowground biomass/residues returned to the plots after harvesting the beans and perhaps also because of changes in microbial activities after legumes (Shipton, 1977;Turco et al, 1990). The same effect is sometimes referred to as allowing subsequent crops to access more P (Johnson et al, 1992;Bainville et al, 2005).…”

A B S T R A C TSoil fertility decline is a major constraint to bean (Phaseolus vulgaris L.) and maize (Zea mays) production in the Central Highlands of Burundi. Nutrient sources, specifically fertilizers, are paramount to increasing the production in the regions. Hence, improving fertilizer use efficiency is considered as a key factor towards sustainable intensification. The use of grain legumes with low harvest indices, such as climbing beans, are assumed to improve soil fertility and fertilizer use efficiency. This study compares the rotational effects of bush and climbing bean varieties on maize and evaluates the profitability of diammonium phosphate (DAP, fertilizer in the bean-maize rotations in 59 smallholder farms of Mutaho district, Gitega Province in Central Burundi. The application of DAP fertilizer significantly increased the grain yields by 14% and 21% for bush and climbing beans, respectively (P < 0.001). Positive effects of bean varieties were large for about 80% of the farmers. Climbing beans in general yielded more than bush beans for about two thirds of the farmers and fertilizer effects were positive. In the bean-maize rotations, the fertilizer induced on average a yield increase of 8% and 22% for maize following bush and climbing beans, respectively. Maize grain yields were significantly (P < 0.001) higher following climbing beans than following bush beans. The value cost ratio (VCR) more than doubled compared with the common practice (bush bean-maize rotation). Variation was substantial, and for approximately 67% of the farmers, DAP application was profitable (VCR > 2 $ $ −1 ) in a climbing bean-maize rotation while 45% of the farmers in a bush bean-maize rotation. Regression tree analysis showed that targeting fertilizer use to soils with higher C and clay content, and ensuring timely planting are the predominant factors to ensure fertilizer response and profitable returns. This study confirms the need for integrated soil fertility management (ISFM), and that a combination of judicious fertilizer use, an improved grain legume (climbing bean) and adjustment to local conditions (targeting to responsive soils) maximizes economic returns of legumecereal rotation systems.
