RESUMOA cultura da batata é a que mais exige a utilização de fertilizantes, em relação a todas as outras culturas produzidas no Brasil. Por isso é importante realizar estudos com novas fontes que possam potencializar o balanço entre nutrientes, melhorar a qualidade física do solo, fornecer nutrientes de acordo com as necessidades da planta e reduzir impactos ambientais. Objetivou-se avaliar a eficiência agronômica de fertilizantes organominerais líquidos em batateira, cultivar Asterix. O delineamento utilizado foi o de blocos ao acaso, com quatro tratamentos e seis repetições. Os tratamentos consistiram na aplicação dos organominerais Acorda+Aminosan+Fitofert; Fitofert; Acorda e uma testemunha, onde não houve aplicação de organomineral. Apenas para produtividade de tubérculos da classe Especial, houve diferença entre os tratamentos, em que a aplicação de Acorda demonstrou ser mais favorável, produzindo 39,83 t ha -1 . Quando aplicados os três produtos testados (Acorda+Aminosan+Fitofert), há efeito negativo na produtividade. Embora os tratamentos não diferenciem em relação ao teor de sólidos solúveis, todos estão dentro da faixa ideal, no nível intermediário, para sua utilização na indústria.

Therefore, it is important to conduct studies in, new sources that can enhance the balance between nutrients, improve soil's physical quality, provide nutrients based on the plant's needs and reduce environmental impacts. The objective this study was to evaluate the efficiency of liquid biofertilizer in potato, cultivar Asterix. The design was a randomized blocks, with four treatments and six replications. The treatments consisted in the application of biofertilizers Acorda + Aminosan + Fitofert; Fitofert; Acorda and a witness where there was no application of biofertilizer. Only for special class tuber yield, was difference between treatments, where the application of Acorda was more favorable, producing 39.83 t ha -1 . When the three tested products applied, there is a negative effect on the productivity. Although the treatments did not differ in relation to soluble solids, all are within the ideal range, at the intermediate level, for use in industry.

“…Regarding the doses of K 2 O, there were no significant increases in productivity as a function of the doses used, with the lowest IBN values. Queiroz et al (2014) also did not observe a significant result for yield of potato tubers with the increase of the doses of K used in the fertilization. Therefore, even expecting high productivity, potassium fertilization may be unnecessary when the initial exchangeable K content of the soil is high.…”

The potato culture has the highest relative demand for fertilizers per unit area, around 2.3 to 2.8 t ha -1 . The objective of this study was to evaluate the productivity of a potato Asterix cultivar subjected to different doses of nitrogen, phosphorus, and potassium, and to establish the DRIS index according to productivity results. The experimental design was randomized blocks, with 5 rates and 4 replicates for each nutrient totalizing 20 plots per experiment. The rates of nutrients were: nitrogen (0, 70, 140, 210 and 240 Kg ha -1 ); phosphorus (0, 200, 400, 600 and 800 kg ha -1 ) and potassium (0, 150, 300, 450 and 600 kg ha -1 ). For leaf diagnosis by the DRIS index, 10 complete leaves of the third expanded trifoliate were collected. The DRIS standards calculations were based on populations of high productivity (or reference) and low productivity. Plants whose productivities were greater than 22 t ha -1 represented the groups of reference. It was concluded that productivity was not influenced by the P and K doses studied, with an increase in yield of tubers as a function of the N rates applied, up to the dose of 173 kg ha -1 of N. According to the DRIS index, it is possible to establish the order of limiting nutrients for failure in descending order in areas with high productivity Ca> Mn> P> S> Zn = Cu> K> N> B> Fe> Mg, and the order of limiting nutrients in areas of low productivity Ca> Cu> Mg> P> S> Mn> Zn> K> Fe = B> N. The results showed that productions above 22 t ha -1 need adjustments of the soil fertility managements.

“…Therefore, the establishment of season-specific DRIS norms is suggested to create adequate indices for the nutritional patterns in pastures.

Batista and Batista (2010) studied the effects of nutrient supply on the nutrient contents of various types of forage grass to determine an adequate nutrient supply for the grass.…”

“…DRIS standards have been successfully used to interpret leaf analysis results in different annual and perennial crops, such as pine (Sanchéz-Parada, López-López, Gómez-Guerrero, & Pérez-Suàrez, 2018); rubber (Chacón-Pardo, Camacho-Tamayo, & Bernal, 2018); sugarcane (Mccray, Ji, Powell, Montes, & Perdomo, 2010;Santos, Donha, Araújo, Lavres Júnior, & Camacho, 2013); common bean (Partelli et al, 2014), potato (Queiroz, Luz, Oliveira, & Figueiredo, 2014), rice (Wadt et al, 2013), cotton (Serra et al, 2013;Kurihara, Venegas, Neves, Novais, & Staut, 2013), guava (Souza, Rozane, Amorim, & Natale, 2013), mango (Politi et al, 2013), orange (Dias et al, 2013), apple (Xu, Zhang, Wu, & Wang, 2015), and grape (Teixeira, Tecchio, Moura, Terra, & Pires, 2015). However, no studies on U. brizantha pastures and their nutritional diagnoses based on DRIS norms are available.…”

To diagnose and monitor the nutritional status of commercial crops, reference standards must be established based on chemical analyses of soils and leaf tissues. Therefore, the objective of this study was to establish sufficiency ranges, DRIS standards and leaf nutritional diagnoses for palisade grass pastures in the rainy and dry seasons. Of a total of 105 sampled pastures, the 20 highest-yielding areas were used to establish reference standards. In the other, low-productivity pastures, the nutritional status was diagnosed in both the rainy and dry seasons for nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), sulfur (S), boron (B), copper (Cu), iron (Fe), nickel (Ni), molybdenum (Mo), and zinc (Zn). A productivity of 15 tons ha-1 year-1 was determined as the threshold to separate high-yielding (> 15 tons ha-1 year-1) pastures from low-productivity pastures (< 15 tons ha-1 year-1). Sufficiency ranges and foliar DRIS standards were established for palisade grass pastures in the rainy and dry seasons, which resulted in the recommendation of region- and season-specific sufficiency ranges and DRIS leaf standards. In the rainy season, in more than 50% of the evaluated pastures, nutritional deficiencies in all nutrients except K, B and Zn were observed, while in the dry season, only N, P, Cu, and Mn were deficient.
