Relevant Factors

The suitable management of nitrogen (N) fertilization can increase barley grain yield, since it is the nutrient required in greater quantity. In this sense, the source and timing of nitrogen application are relevant factors. The objective was to evaluate the effects of N sources and splitting on the performance of barley. The experiment was carried out under a clayey Cambisol (550 g kg-1), in Curitibanos, Santa Catarina. Factorial randomized blocks were used: three mineral sources of N: urea (45% N); urea with urease inhibitor-NBPT (45% of N) and nitrate (30% of N), associated with two nitrogen splitting fertilization: i) split of the rate of N in two seasons: beginning of tillering and full tillering and ii) single application at full tillering. 100 kg ha-1 of N were applied. There was no interaction between the factors and there was no effect of treatments for plant height, ear length, grains per ear, ears per m² and mass of a thousand grains. Yield was influenced by the N source, where nitrate exceeded the yield from amidic sources by 16%. The splitting of N in two times did not present advantages over the single application. Urea with NBPT was not viable in relation to readily soluble forms of N, with the highest yield obtained with a nitric source.

Dicyandiamide (DCD) was tested as a nitrification inhibitor with urea in 10 field experiments (ammonium nitrate was included in 2 of them) in 3 years on sites where leaching of nitrogen was a potential problem. The investigations included different rates and times of nitrogen application. At 1 site in 1982 and 2 in 1983 the soil was sampled to 30cm throughout the season. Nitrification of ammonium nitrogen was delayed by DCD (applied as a mixture with urea and supplying 10% ofthe nitrogen in the mixture) by up to 30 days compared with untreated urea and reduced the danger of nitrogen leaching. Early sampling at the 1982 site showed increased uptake of ammonium nitrogen and decreased nitrate nitrogen in wheat plants receiving DCD-treated urea compared with those receiving untreated urea. This confirmed that DCD inhibits nitrification. The only significant (P<0.05) grain yield increase from DCD was a 22% increase from an application of nitrogen at sowing on a particularly highly leaching soil. DCD significantly (P < 0.05, P < 0.01) reduced grain yield (7 and 8%) and vegetative yield (1 3 and 9%) at 2 sites. DCD increased vegetative yield by 16% at 1 site (not the same site as the grain yield increase). In 2 of 3 experiments plant dry matter production (up to 11 weeks after sowing) was significantly (P < 0.05 to P < 0.001) reduced (up to 30%) by DCD application. The final value of the use of DCD will depend on the balance between the benefit in preventing nitrogen losses by leaching at a particular site and the harm caused by suppressing early plant growth.
