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.

Local Cultivar

More than 250 rice varieties are grown in Indonesia from new superior varieties and local varieties with aromatic, non-aromatic aromas and pigmented rice. Rice quality is one factor that must be considered in addition to high productivity. Generally, the quality of grain and rice quality in Indonesia have met the quality standards set based on SNI 0224-1987/SPI-TAN/01/01/1993 and SNI 6128:2020. Ricequality is determined by several factors such as grain appearance, nutritional value, cooking and eating quality and become one of the foremost considerations for rice buyers. Such information can be utilized as basic data of character of genetic resources on assembling of new superior varieties by rice breeders. Those information can be used as a descriptive information for farmers and rice productivity, high yield, and better rice quality. Good quality local cultivar can be used as parents for the formation of new superior varieties.

Tasting Panel

A 10-12 member tasting panel appraised cooked samples of 26 rice varieties as to appearance, cohesion, tenderness, and flavor; and judged 25 of those varieties for eating quality using a +2, -2 (acceptable-not acceptable) scale. All samples had good cooking characteristics. The eating quality of IR-8 and Chontalpa 59 was questionable. An additional test showed preference for Sunbonnet and Starbonnet. Bluebelle was very close to the significant level of preference. The commercial sample came close to a significant level of preference over Chontalpa 59.

Time Of Application

The timing of nitrogen application in oats improves the efficiency of use of the nutrient, expressing the yield and industrial quality of grains. The objective of the study is to indicate the appropriate timing of nitrogen supply on the yield and industrial quality of oat grains, considering the use of low and high dose of nitrogen at sowing and favorable and unfavorable years for cereal growing in soybean/oat system. The experiment was conducted in the years 2016, 2017 and 2018, in Augusto Pestana, RS, Brazil. The experimental design was a randomized block with four replications in a 2 x 4 factorial, for two doses of nitrogen at sowing (5 and 25 kg ha-1), changing the top dressing dose by the total supplied of 70 kg ha-1, in the expectation grain yield of 4000 kg ha-1, with time of supply at 0, 10, 30 and 60 days after emergence. In an unfavorable and intermediate year for the growing of oats, it is necessary to increase the dose of the nutrient at sowing in order to favor greater amplitude of the time of application in top dressing. In a favorable year, whether low or high, this range of application is guaranteed. Regardless of the reduced and high dose of nitrogen at sowing, the greatest expression of grain and industry yield occurs with the nutrient applied at 30 and 35 days after emergence in an unfavorable year, 35 days in an intermediate year and 40 to 45 days in a favorable year, respectively.
