“…Millet is one of the most cover crop used in the Cerrado region of Brazil. Millet vigorous initial growth can be an important forage to anticipate animal stocking compared to perennial forages, once Millet is prompt to be grazed in 30 days after seeds emergence while the other forages in this study takes at least 45 days after seeds emergence (Machado & Assis, 2010;Andrade et al, 2017). Based on the inherent differences among Millet and perennial forages investigated, lower Millet DM compared to Soybean+P.…”

Soybean is the major crop in the Brazilian Cerrado region. Tocantins state has been increasing soybean production mostly into degraded pasture. However, cover crops such as forages crops are important to implement in regional soybean agricultural systems to increase systems resilience due to climate variability. There is a lack of information regarding to agronomic performance of soybean intercropped with cover crops under no-tillage. The experimental design was randomized complete blocks with four replications in factorial 7 × 2. Seven soybean cultivation systems were tested: 1) soybean intercropped with Urochloa brizantha cv. Marandu; 2) soybean intercropped with Urochloa ruziziensis; 3) soybean intercropped with Panicum maximum cv. Mombaça; 4) soybean intercropped with Panicum infestans cv. Massai; 5) soybean intercropped with Pennisetum americanum; 6) soybean followed by Pennisetum americanum; and 7) soybean and fallow. Two soil acidity and amelioration were tested: 1) with lime and gypsum application; 2) without lime and gypsum application. Soybean grain yield, plant height and number of pods per plant were different. Soybean grain yield were higher with lime ad gypsum application. The highest soybean plants height were observed in the treatments where lime and gypsum were applied, and with soybean intercropped with P. maximun and Millet. Soybean number of pods was positively affected P. infestans intercropped with soybean. There was no significant difference among treatments for mass per 100 seeds. Cover crops showed suitable to increase agronomic performance of soybean.

“…The absence of difference at this initial moment of establishment of the Sm, SMh and SMRh systems was expected, due to procedures of soil tillage and initial conditioning of fertility. Thus, the 'constructed' fertility nullified possible effects of the intensification process, which until then was restricted to the increase in maintenance fertilizer (Figure 2), considering that the ruzigrass oversown in the soybean maturation stage has no interference in the yield of the respective harvest (ANDRADE et al, 2017).…”

“…This intensification involved species diversification and two levels of investment in the maintenance fertilizer (Figure 2). The treatments were formed as follows: System 1 -Soybean monocropping with medium investment in fertilizer (Sm); System 2 -Maize monocropping with medium investment (Mm); System 3 - In the systems with inclusion of ruzigrass, the grass seeds were distributed mixed to the fertilizer in the sowing furrow of maize and broadcast during the reproductive stage of soybean (phenological stage R5.5), according to Andrade et al (2017).…”

This work aimed to evaluate the agronomic responses to the intensification of grain production systems under water restriction in the central region of Minas Gerais State, Brazil. We studied six systems, including soybean and maize monocropping with medium investment in maintenance fertilization, and the annual alternating of these crops in medium or high investment, with inclusion or not of ruzigrass for straw increment. Soybean and maize in monocropping lose yield potential over time compared to their alternating cultivation. Greater fertilization in soil with built fertility does not increase the yield accumulated until the fourth harvest. The intercropping with ruzigrass can hamper maize yield under lower fertilization. The ruzigrass increases the average production of residues for straw formation in the soybean/maize system, approaching 8 ton.ha -1 .year -1 . After four crop seasons, differences in soil chemical attributes are still not evident due to the diversification/intensification of the production system.

“…Strategies must be created to increase the efficiency of P availability in the soil and reduce strong dependence on imported phosphate fertilizers. One noteworthy alternative is reuse of P from livestock residues associated with conservationist systems, such as the integrated crop-livestock (iCL) system, which can further enhance the efficiency of P availability in the soil (Crusciol et al, 2015;Andrade et al, 2017;Prochnow et al, 2018).…”

Use of organic fertilizers in integrated crop-livestock (iCL) systems may affect soil phosphorus fractions. This study aimed to determine phosphorus fractions in the soil under the iCL system after six years of application of organic or mineral fertilizers. The experiment was conducted on a Rhodic Kandiudox (Nitossolo Vermelho Distroférrico) in a randomized block design, using a 5 × 3 + 1 factorial scheme, with four replicates. The treatments consisted of three organic fertilizers (poultry litter, pig slurry, and compost) and two mineral fertilizers (M1, equivalent to pig slurry; and M2, equivalent to poultry litter) in interaction with three application rates, corresponding to 75, 100, and 150 % of the fertilizer recommendation for the crop of interest and a control (with no fertilizer). Soil sampling was performed in the 0.00-0.05, 0.05-0.10, and 0.10-0.20 m layers for determination of the phosphorus fractions. Successive use of organic or mineral fertilizers for six years in the iCL system considerably raises the labile and moderately labile P fractions up to the 0.20 m depth and, with less intensity, raises the non-labile fractions up to the 0.10 m depth. The soil P increase associated with fertilizer input raises soybean and corn yields, and it does not exceed the critical P limit according to local environmental legislation.
