“…Thus, increasing doses of this nutrient may supply nitrogen to the soil microflora and make more nitrogen available for the rice plants. Gitti et al (2012a) and Stone et al (1999) also observed an increase in rice plant dry mass, in association with higher amounts of applied N doses.…”

“…Thus, studies are needed to determine the appropriate nitrogen dose to improve the fertilization efficiency, especially in no-tillage areas that use cover crops. Silva et al (2016) studied the use of nitrogen fertilizer (0 kg ha -1 , 20 kg ha -1 and 20 + 60 kg ha -1 ) and different cover crops (crotalaria, pigeon pea, mucuna, millet and fallow) with upland rice and found that the rice yield was higher when rice was sown after millet and after the field had lain fallow, situations associated with the highest amounts of applied nitrogen. However, when rice was sown after leguminous cover crops, an increase in rice yield was detected even with an application of only 20 kg ha -1 of N.…”

“…This difference is due to the higher accumulation of N by the corn + jack bean residues (106 kg ha -1 ), which increased the availability of the nutrient, if compared to the single corn crop (60 kg ha -1 ). For the uptake of nitrogen fertilizer and cover crops for upland rice, Silva et al (2016) determined that, with accumulations of 196 kg ha -1 of nitrogen in Crotalaria juncea and 84 kg ha -1 in millet plants, of the total nitrogen content in rice plants sowed in succession with Crotalaria, 74.1 % **, * and ns significant at 1 % and 5 % of probability and not significant, respectively, by the F test. Mean values followed by the same letters are equivalent, based on the Tukey test at 5 % of probability.…”

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.

“…The adoption of cover crops provided 150% more N accumulation than did the fallow treatment. Silva et al (2016), researching the use of N fertilizer and cover crops with upland rice, concluded that the inclusion of legumes (sunn hemp, pigeonpea, and mucuna [Mucuna pruriens (L.) DC.]) resulted in higher grain yield and efficiency of N fertilizer use than millet or fallow treatments.…”

Global rice (Oryza sativa L.) cultivation is expected to increase, especially in upland no‐tillage systems (NTS). The difficulty in producing and maintaining straw in NTS in the Brazilian Cerrado and comparative regions worldwide can be overcome by using cover crops in irrigated areas. The potential of straw accumulation, soil cover maintenance, and nutrient cycling is considered while choosing cover crop species, because these characteristics may interfere with subsequent crop cultivation. This study was conducted to determine whether cover crops could benefit the development, productivity, and industrial quality of upland rice grains irrigated by sprinklers and cultivated in succession. The experiment was conducted in the Cerrado, with a summer rainy season and a dry winter. The treatments consisted of six cover crops (millet [Pennisetum glaucum], sunn hemp [Crotalaria juncea], pigeonpea [Cajanus cajan], millet + sunn hemp, millet + pigeonpea, and fallow) sowed in winter or spring. Compared to fallow, the cover crops cultivated in winter or spring led to increased straw production, accumulation of approximately 150% more nitrogen in straw, and possibly improved rice nutritional value because of the higher N content. Rice plants cultivated after sunn hemp developed a greater dry mass than rice cultivated after the fallow treatment. Grain yield was not influenced by the cover crops. However, sunn hemp cultivation increased the milling yield, head rice yield, and the milled rice productivity (MRP), compared to cultivation following the fallow treatment. Cultivation of sunn hemp before the upland rice crop improved MRP compared to that following the fallow treatment.

“…In Brazil, several researchers have been studying factors that could increase the productivity of upland rice, especially in the Cerrado, a region where rice cultivation can be introduced to integrate the crop rotation system. Among the most studied factors the mineral fertilization with nitrogen (Arf et al, 2005;Cazetta et al, 2008;Hernandes et al, 2010;Gitti et al, 2012;Artigiani et al, 2012;Arf et al, 2015;Silva et al, 2016), phosphorus (Tokura et al, 2007;Garcia et al, 2009;Rotili et al, 2010;Fidelis et al, 2013), potassium (Fageria, 2000;Silva et al, 2002;Zaratin et al, 2004;Barbosa Filho et al, 2006), and nitrogen, phosphorus and potassium (Crusciol et al, 2003;Guimarães and Stone, 2004;Dias et al, 2010;Yamashita et al, 2013;Soares et al, 2015) are evident. However, there are few studies using organic fertilizers on upland rice in Brazil and in the world.…”

Due to the expansion of the slaughterhouses sector, there is huge availability of waste from agricultural products. These waste products may be used as alternative for the production of organic fertilizers. Fertilizer efficiency depends on the type of rice cultivar. Thus, traditional, intermediate and modern plant types may respond differently to the combined use of mineral and organic fertilizers. The objective of this study is to evaluate the effects of different combinations of mineral and organic fertilizers based on slaughterhouse waste on the development, productivity and industrial quality of upland rice cultivars. The soil of the the experimental area was a typical clayey dystroferric Red Latosol and the climate of the region is Aw: humid tropical, rainy in the summer and dry in the winter according to the Koppen classification. The experimental design was randomized blocks arranged in a 3 x 6 factorial design. We evaluated three different types of rice cultivars (Caiapó, traditional type; BRS Primavera, intermediate type; and IAC 202, modern type) and levels of combinations of mineral and organic fertilizers (100% mineral, 80% mineral + 20% organic, 60% mineral + 40% organic, 40% mineral + 60% organic, 20% mineral + 80% organic, 100% organic). The cultivar IAC 202 presented a productive potential higher than the cultivars Caiapó and BRS Primavera. The 60% mineral + 40% organic and 40% mineral + 60% organic fertilizer combinations produced more yield in comparison with the 100% organic fertilizer. The cultivar Caiapó showed the highest grain quality. Organic fertilizer based on slaughterhouse waste can be used for upland rice farming.
