“…The observed increase in plant dry biomass, plant tillering, panicle density, number of grains per panicle and grain yield as a response to potassium application support other studies on the positive effects of K application on rice grain yield in the Cerrado region and elsewhere (Zaratin et al 2004;Fageria et al 2011;Fageria 2015). According to Fageria (2015), 17% of the agricultural land area is deficient in potassium in Africa, 21% in Asia and 29% in Latin America.…”

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.

“…Phosphorus accumulated in shoot and roots were estimated by multiplying nutrient concentrations in tissues and the amount of DM accumulated. From the amount of DM and P in plants, the following indexes were calculated: (a) P use efficiency = total DM / total amount of P in plants (Fageria et al, 1997); (b) uptake efficiency = total amount of P in plants / root DM (Swiader et al, 1994); (c) translocation efficiency = (amount of P in shoot / total amount of P in plants) x 100 (Li et al, 1991).…”

SUMMARYHigh rates of phosphate fertilizers are applied to potato (Solanum tuberosum L.), which may cause antagonistic interactions with other nutrients and limit crop yields when over-supplied. The purpose of this study was to evaluate the influence of phosphorus (P) levels in nutrient solution on P use efficiency, nutritional status and dry matter (DM) accumulation and partitioning of potato plants cv. Ágata. The experiment was carried out in a greenhouse, arranged in a completely randomized block design with four replications. Treatments consisted of seven P levels in nutrient solution (0, 2, 4, 8, 16, 31, and 48 mg L -1 ). Plants were harvested after 28 days of growth in nutrient solution, and separated in roots, stems and leaves for evaluations. The treatment effects were analyzed by regression analysis. Phosphorus levels of up to 8 mg L -1 increased the root and shoot DM accumulation, but drastically decreased the root/shoot ratio of potato cv. Ágata. Higher P availability increased P concentration, accumulation and absorption efficiency, but decreased P use efficiency. Higher P levels increased the N, P, Mg, Fe, and Mn concentrations in roots considerably and decreased K, S, Cu, and Zn concentrations. In shoot biomass, N, P, K, and Ca concentrations were significantly increased by P applied in solution, unlike Mg and Cu concentrations. Although higher P levels (> 8 mg L -1 ) in nutrient solution increased P concentration, accumulation and absorption efficiency, the DM accumulation and partitioning of potato cv. Ágata were not affected.Termos de indexação: Solanum tuberosum, dry matter, mineral nutrition, nutrient interaction.(1) Received for publication in November 11, 2011 and approved in July 16, 2012.

“…Phytoavailability of N, K, P, or S often limits low-input agriculture (Fageria et al, 2011 andMueller et al, 2012). Moreover, sorghum is a C4 annual crop which can produce high forage biomass yields per unit of area (Rooney et al, 2007) and uses nitrogen in a more efficient way compared to most C3 crops (Young & Long, 2000).…”

ETEROSIS and combining ability for grain yield and some …….agronomic traits were studied among thirty F1 grain sorghum crosses and their elven parents under three NPK levels during 2014 and 2015 seasons. Significant differences among genotypes were found for all studied traits, indicating wide genetic diversity. The interaction of genotypes with each of years and NPK levels were significant in most studied traits. The analysis of variance for combining ability revealed that the mean square due to entries, parents, parents vs. crosses, crosses, lines, testers, lines × testers turned up significant for all studied characters and suggesting that the experimental materials possessed considerable variability that both general and specific combining ability were involved in the genetic expression of these characters. The female line ICSB610 showed significant and negative general combining ability (GCA) effects for days to 50% heading and panicle length and positive for grain yield and plant height. It may be used to develop high yielding, early flowering, and tall hybrids with short panicles. For specific combining ability (SCA), effects, the crosses ICSA613 × ICSR89028 and ICSA20 × ICSR53 gave positive and highly significant SCA effects which indicated that these crosses can be considered desirable combiners. These crosses had also high grain yield per se and one of the parents with highest GCA effects. The observations on portioning of combining ability variance into additive and dominance variances indicated the role of both additive and dominance gene action. The magnitude of non-additive variance was higher than the additive variance by many folds for all studied traits.
