ABSTRACT The Brazilian Savannah region presents a great potential for the expansion of upland rice crops. However, studies are necessary to identify practices that can improve the crop performance, especially in no-tillage systems. This study aimed to assess the effect of cover crops in association with corn on the development and yield of rice cultivated in rotation and cover fertilized with nitrogen doses. The sprinkler irrigation system was used and the experiment was developed in the 2014/2015 and 2016/2017 harvest years, using a randomized block design, in a 5 × 4 factorial scheme. The treatments consisted of the crop remains combinations of single corn crop, corn + Crotalaria spectabilis, corn + pigeon pea, corn + jack bean and corn + Urochloa ruziziensis, as well as cover nitrogen doses (0 kg ha-1, 40 kg ha-1, 80 kg ha-1 and 120 kg ha-1) in the rice. The cultivation of upland rice in rotation with corn + pigeon pea was favored by the greater soil cover and nitrogen supply via cycling, if compared to the rotation with single corn crop. The intercropped corn + pigeon pea cultivation in the previous summer resulted in a 15 % increase in the yield of rice grains seeded in the rotation, when compared to the single corn crop. The cover nitrogen application positively influenced the grain yield with the maximum estimated doses of 46 kg ha-1 and 105 kg ha-1 of nitrogen, respectively in the 2014/2015 and 2016/2017 harvest years.

This work aimed, to evaluate the structural behavior of Oxisols based on the least limiting water range (LLWR) and establish relations with corn crop. The experiment was carried out in a randomized block design with five treatments and four replications. Soil samples collected at the layer of 0-0.20 m depth in a Haplustox (LVd) and an Eutrustox (LVef) were used. The compaction treatments consisted of T0= no additional compaction; T1 and T2= two and four passes with a 4 t tractor, respectively; T3 and T4 = two and four passes with a 10 t tractor, respectively. The range of LLWR variation in the LVd was the lowest one and varied from 0.01 to 0.04 m3 m-3, whereas in the LVef varied from 0.03 to 0.13 m3 m-3 for the critical soil penetration resistance (PRc) of 2 MPa. It was observed that critical bulk density (BDc) values were 1.76 and 1.40 Mg m-3 in the LVd and the LVef, respectively. The highest frequency of bulk density (BC ≥ BDc) occurred from the T1 to T4 (LVd) and from the T2 to T4, however, a reduction in corn yield was not observed. The determination of the LLWR was efficient and complementary for identifying more favorable or more impeditive conditions to compaction in the LVef for the corn crop development in relation to the LVd.

Biodiversity loss due to increasing anthropogenic activities is one of the biggest threats to humanity. Understanding the impacts of multiple-stressors on ecosystems and biodiversity is therefore an urgent task. Shore ecosystems are especially valuable, as they harbour a high biodiversity and provide important ecosystems services. Until now, experimental approaches addressing multiple-stressor impacts on these ecosystems have been rare and mostly run with a limited number of replicates and under non-natural conditions. Here, an experimental field mesocosm system that allows studying multiple-stressor impacts on rock pool biodiversity is proposed. The ExMarine mesocosm system is composed of 64 experimental rock pool mesocosms in a fully randomised block design, which allows studying multiple-stressor impacts under highly standardised conditions. Water is taken directly from the sea, allowing biota to immigrate and emigrate freely. Water flow into the mesocosms can be regulated and it is possible to simulate disturbance through waves during high tide. The system can help to understand the impacts of multiple stressors on biodiversity, to monitor ecosystem health and to plan measures preventing the further loss of biodiversity.

Keterbatasan lahan potensial menyebabkan perluasan areal pertanian mengarah pada lahan gambut. Kendala pengembangan lahan gambut adalah rendahnya kandungan hara tersedia bagi tanaman. Fosfat (P) merupakan salah satu unsur hara makro yang penting untuk pertumbuhan dan produksi tanaman, disisi lain ketersediaan hara ini pada lahan gambut terbatas karena ikatan asam organik dan sifat yang mudah tercuci. Penelitian untuk menguji pengaruh ameliorasi dan inokulasi mikroba pelarut fosfat terhadap ketersediaan hara P di lahan gambut dilakukan di kebun pembibitan kelapa sawit petani di Riau dari Oktober 2013 - Maret 2014, menggunakan Rancangan Acak Kelompok pola Faktorial dengan 30 kombinasi perlakuan dan 3 kali ulangan. Variabel yang diamati meliputi : tinggi tanaman, lingkar batang, jumlah daun, lebar daun, panjang daun, kandungan hara tanaman, dan bobot biomasa bibit setelah 5 bulan di pembibitan. Hasil penelitian menunjukkan bahwa ameliorasi menggunakan kompos tandan kosong kelapa sawit mampu meningkatkan P tersedia, serapan P oleh batang dan akar, berat brangkasan dan berat kering batang. Sedangkan mikroba pelarut fosfat berpengaruh secara tidak nyata.The limitation of potential land leads agricultural development expansion to the peat soil area. Constrain of the peatland development is the low nutrient content that is required by plant. Phosphate is one of major growth and production limiting nutrient because of the solublelize of the organic acids and immobility The research was conducted from October 2013 – March 2014 at the farmer main nursery in Riau province to test the effect of amelioration and phosphate solubilizing microbe inoculation on P availability on palm oil seedling growth and production at peatland, used Randomized Block Design with 30 treatments and 3 replications. The parameters observed were plant height, leaf number, leaf width, leaf length, stem diameters, nutrient contents, also fresh and dry weight after 5 months at the main nursery. The result showed that palm oil empty fruit bunch compost as ameliorant increased P nutrient avaibility, P uptake, fresh and dry weight, whereas phosphate solubilizing microbe was unsignificant.
