“…As a consequence, intercropping removes more nutrients from the soil than corresponding monocrops and this has been observed in the present study and also in previous studies (Xia et al 2013;Yang et al 2013;Zhang and Li 2003). Faba bean/maize intercropping N acquisition enhancement ranged from 9 to 32 % compared with monocultures at different N levels (Li et al 2011b).…”

Background Overyielding (i.e., mixtures of crops yielding higher than expected when compared with monocultures) and increased nutrient acquisition have been found in many intercropping systems. However, there are very few published studies on long-term changes in soil chemical and biological properties in intercropping systems compared to sole cropping. Methods A field experiment was established in 2003 in Gansu province, northwest China. The treatments comprised three intercropping systems (either continuous or rotational wheat/maize, wheat/faba bean, maize/faba bean intercropping), rotational cropping (wheat-maize, wheat-faba bean, faba bean-maize, and wheat-maizefaba bean rotations), and monocropping (sole wheat, faba bean and maize) systems. In 2011 (ninth year of the experiment) and 2012 (tenth year) the yields and some soil chemical and biological properties were examined after all crop species were harvested. ResultsThere was overyielding by 6.6 % and 32.4 % in wheat/maize intercropping in 2011 and 2012, respectively. Faba bean/maize intercropping was enhanced by 34.7 % and 28.6 %, respectively but not wheat/faba bean intercropping. Soil organic matter, total nitrogen, Olsen P, exchangeable K and cation exchange capacity in all intercropping systems did not differ from the monocultures except for soil pH in wheat/maize and faba bean/maize intercropping in 2011 and soil exchangeable K and cation exchange capacity (CEC) in 2012. Soil pH in wheat/maize and faba bean/maize intercropping was significantly reduced by 3.2 % and 1.9 %, respectively. Soil exchangeable K in wheat/ maize, faba bean/maize and wheat/faba bean intercropping declined markedly by 15 %, 21.7 % and 12.1 %, respectively. Soil cation exchange capacity in wheat/maize, faba bean/maize and wheat/faba bean intercropping was notably lower than the corresponding monocultures by 17.5 %, 23.3 % and 18.3 %, respectively. Soil enzyme activities after 9 and 10 years of intercropping differed little from monocultures or rotations.Conclusions The results indicate that intercropping overyielded compared with monocropping or rotational cropping and also maintained the stability of most of the soil chemical and enzyme activities relative to rotations and monocropping in the relatively fertile soil studied.

“…Many studies have found sucrose content to be unaffected by N fertilization Thorburn et al, 2011;Yang et al, 2013), while in some cases a nega- As expected, the efficiency of 15 N recovery was decreased by higher application rates. The main fate of N fertilizer (about 20 to 40 %) applied to sugarcane is to remain in the soil, where the N immobilized by microorganisms resides in the organic fraction and is temporarily unavailable to the crop (Gava et al, 2005;Oliveira et al, 2000).…”

The low effectiveness of nitrogen fertilizer (N) is a substantial concern that threatens global sugarcane production. The aim of the research reported in this paper was to assess the residual effect of N-fertilizer applied at sugarcane planting over four crop seasons in relation to sugarcane crop yield. Toward this end three field experiments were established in the state content at the other, whereas the only residual effect was higher sucrose content in one of the following ratoons. The combined effect was an increase in sugar yield for three of the 11 crop seasons evaluated. Over the crop cycle of a plant cane and three ratoon crops, only 35 % of the applied N was recovered, split 75, 13, 7 and 5 % in the plant cane, first, second and third ratoons, respectively. These findings document the low efficiency of N recovery by sugarcane, which increases the risk that excessive N fertilization will reduce profitability and have an adverse effect on the environment.

Resumo -O objetivo deste trabalho foi avaliar a produção de matéria seca e o controle de plantas daninhas por espécies de leguminosas consorciadas com cana-de-açúcar, em cultivo orgânico. As espécies leguminosas Arachis pintoi, Cajanus cajan, Calopogonium mucunoides, Crotalaria anagyroides, Crotalaria juncea e Stylosanthes 'Campo Grande' foram semeadas em novembro de 2012, nas entrelinhas da cana-de-açúcar. O delineamento experimental em blocos ao acaso foi utilizado com quatro repetições e dois controles -um tratamento capinado e outro sem capinar. A massa de matéria seca das leguminosas foi avaliada aos 142 dias após a semeadura (DAS), e a massa de matéria seca de plantas daninhas, aos 29, 85 e 142 DAS. A massa de matéria seca de plantas daninhas foi inferior à da testemunha em todas as épocas amostradas. A produção de massa de matéria seca das leguminosas no consórcio foi baixa. As espécies Crotalaria juncea, Cajanus cajan e Calopogonium mucunoides produziram massa de matéria seca superior à das espécies Arachis pintoi e Stylosanthes 'Campo Grande'. A produtividade de colmos da cana-de-açúcar não foi afetada pelo consórcio. O consórcio entre cana-de-açúcar orgânica e leguminosas com semeadura tardia, para adubação verde, é eficiente no controle de plantas daninhas.Termos para indexação: Saccharum, açúcar orgânico, adubo verde, manejo cultural, planta de cobertura. Dry matter production and weed control by intercropped legumes with sugarcane in organic croppingAbstract -The objective of this work was to evaluate dry matter production and weed control by intercropped legumes with sugarcane, in organic cropping. The legume species Arachis pintoi, Cajanus cajan, Calopogonium mucunoides, Crotalaria anagyroides, Crotalaria juncea, and Stylosanthes 'Campo Grande' were sown on November 2012 in the inter-rows of sugarcane. A randomized complete block experimental design was used with four replicates and two controls -a weeded treatment and an unweeded one. Legume dry matter was evaluated 142 days after sowing (DAS), and the weed dry matter, at 29, 85, and 142 DAS. Weed dry matter was lower than that of the control in all sampling periods. The production of legume dry matter was low in intercropping. The species Crotalaria juncea, Cajanus cajan, and Calopogonium mucunoides produced higher dry matter than the species Arachis pintoi and Stylosanthes 'Campo Grande'. Stalk yield of sugarcane was not affected by intercropping. The intercropping of organic sugarcane and legumes in late sowing, for green manure, is efficient for weed control.
