“…Further, additional gains in grain yield would be expected to result from improved fertilizer management. The use of a correctly balanced supply of nutrients from addition of fertilizers is expected to result in significant increases in grain yield (Fageria 2014b;Nascente et al 2011;Nascente and Lanna 2016). Nitrogen, N, is the nutrient that most limits plant development, biomass and grain production in most crops (Fageria, 2014a).…”

The upland rice farmers in Suriname use local varieties and low level technologies in the field. As a result, the upland rice grain yield is low, at about 1 000 kg ha -1 . Our objective was to evaluate the use of upland rice cultivars from Suriname and Brazil, and the effect of nitrogen, N, phosphorus, P, and potassium, K, fertilizers on cultivation variables. We undertook four field trials in the Victoria Area, in the Brokopondo District, using a randomized block design each with four replications. The most productive rice varieties were BRS Esmeralda (grain yield 2 903 kg ha . Together, these application rates of N, P and K resulted in rice grain yield of about 3 000 kg ha -1 , which is three times greater than the national average for upland rice. We demonstrate that the use of improved rice varieties matched to the local conditions, and application of appropriate fertilizers, are management practices that can result in significant increases in rice grain yield in Suriname.

“…Nitrogen is a structure nutrient and it is expected that its increases provide increases in plant development, yield components and grain yield (Fageria, 2014). Hernandes et al (2010), Fageria et al (2011), Nascente and Lanna (2016) and Fageria (2014) reported that nitrogen fertilization in rice is directly related to increased crop productivity.…”

The use of nitrogen-fixing diazotrophic bacteria such as Azospirillum spp. could be an important alternative to reduce nitrogen fertilization in upland rice field. The objective of this study was to determine the effect of nitrogen application at topdressing and seed inoculation with strains of Azospirillum spp. on the plant biomass, foliar nutrient concentration, yield components, grain yield and nutrient concentration of grains in upland rice under a no-tillage system. The field experiments were conducted for two growing seasons 2015/2016 and 2016/2017 in the Cerrado Region of Brazil. The experimental design was a complete randomized block in a factorial 4x4 scheme with three replications. The treatments consisted of inoculated seeds of rice with peat containing the strains of Azospirillum spp. [Azospirillum brasilense 245, Hernaspirillum seropedicae Z94, commercial Azospirillum brasilense (Ab V5 and Ab V6 strains), and without Azospirillum] with four doses of N (0, 40, 80 and 120 kg ha-1) applied as urea at topdressing. The use of diazotrophic bacteria in high level of soil organic matter did not increase yield components, grain yield and nutrients in the leaves and grains of upland rice. Increasing rates of N increased N, P, K, Ca, Mg, S, Cu and Mn in leaves; N, P, Ca, Cu and Fe in the grains, biomass, panicle per meter, grain per panicle and grain yield of upland rice. In this sense, the rate of 120 kg ha-1 of N provided the highest rice grain yield (4,413 kg ha-1).

“…The MCB and UF showed linear and quadratic patterns (Table 1). The increase of N levels has a significant effect on NH 4 + and NO 3 concentrations in the soil and NRA in the rice (Nascente and Lanna, 2016). The applications of 13.29 tons ha -1 of MCB and 245.35 tons ha -1 of UF increased the NRA content by 35.28%, compared to a single UF application by 300 kg ha -1 (Nurmalasari et al 2020).…”

Background: The main problem in nitrogen fertilization for crop cultivated is the very low efficiency due to the leaching process. The purpose of this study was to the determination of the optimum levels of biochar amendment made from Melaleuca cajuputi biochar (MCB) and urea fertilizer (UF) for nitrogen use efficiency in upland rice under M. cajuputi stands.Methods: The study was conducted during dry season within March to June 2019 in Menggoran Forest Resort, Playen Forest Section, Yogyakarta Forest Management District, Indonesia. The experimental design was laid out in a randomized complete block design factorial with three replications as the response surface methodology (RSM). The treatments consisted of MCB levels (0, 5, 10, 15 tons ha-1) and UF levels (0, 100, 200, 300 kg ha-1) as independent variables. The observation parameters were nitrate reductase activity (NRA), total chlorophyll (TC), leaf photosynthesis rate (LPR), nitrogen loss (NL), nitrogen use efficiency (NUE) and seed yield (SY). The data was analyzed using RSM approach and ridge regression.Result: The optimizing applications of 11.14 tons ha-1 of MCB and 281.13 kg ha-1 of UF resulted in NUE and SY by 2.14 kg grain kg Nfertilizer-1 and 5.83 tons ha-1 or increased by 19.07% and 13.02%, compared to a single application of UF by 300 kg ha-1.
