Many methods of nutritional diagnosis present discordant reports. It is necessary to study how these diagnoses relate to agricultural productivity and nutrient balance for a more efficient nutritional monitoring of the crops. This study had two objectives: (1) evaluate and compare Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrient Diagnosis (CND) methods for nutritional diagnosis of sugarcane cultivated in the Northeast of Brazil; (2) establish standards, identify and hierarchize nutritional limitations. The database consisted of 183 samples, in which 31 were in areas with high productivity (³ 80 Mg ha-1) and 152 of areas with low productivity (< 80 Mg ha-1). Sugarcane leaves were collected and contents of N, P, K, Ca, Mg, S, Fe, Zn, Cu, Mn and B were determined. The DRIS indexes were calculated by methods DRIS-Beaufils, DRIS-Jones, DRIS-Elwali and Gascho, M-DRIS Beaufils, M-DRIS Jones, and the indexes CND too were calculated. The DRIS-Beaufils, DRIS-Jones, M-DRIS Beaufils and M-DRIS Jones methods tended to agree on the nutritional diagnosis of sugarcane. The nutritional diagnosis of the CND method interpreted by the Potencial Fertilization Response (PFR) was different from the DRIS methods for N and Mn nutrients. The M-DRIS Beaufils and M-DRIS Jones methods showed a higher correlation with nutrient contents. However, there was no significant correlation between agricultural productivity and nutrient balance index mean (NBIm), suggesting that other factors influenced sugarcane production more than nutritional factors. The nutritional diagnosis methods identified excessive fertilization with N and limitations of Ca, Mg, K, S, Mn, Cu, Zn and B in sugarcane in the Northeast of Brazil.

Paratecoma peroba is a native forest species of great economic and ecological interest, currently at risk of extinction from selective and illegal exploitation; however, there are no established parameters for the production of seedlings of this species. The objective of this study was to analyze the growth and nutritional balance of P. peroba seedlings grown in polypropylene tubes of different sizes with variable doses of controlled-release fertilizer (CRF). Three volumes of tubes (120, 180, and 280 cm3), four CRF doses (0, 2.5, 5, and 7.5 kg m-3), and a conventional mineral fertilizer (CF) were tested as indicated in the literature for native forest species: arranged in a completely randomized design in a 3 × 5 factorial scheme, with four replicates composed of 16 seedlings. After 180 days, the percentage of survival, growth variables, indices of the diagnosis and recommendation integrated system, and the average nutrient balance index of the seedlings were analyzed. Based on the total dry matter and the mean nutritional balance index, the combination of a 280 cm³ tube with a 7.5 kg m-3 CRF dose was the most effective in the production of P. peroba seedlings.

Plant nutrition is one of the most important factors for successful cultivation of tomatoes, especially in the greenhouse, and Diagnosis and Recommendation Integrated System (DRIS) is an alternative for fertilizer recommendation. This study aimed to establish DRIS norms for tomato plants growing in greenhouse located at Norte Pioneiro do Paraná region (Paraná State, Brazil). Chemical analysis of nutrients on leaves (N, P, K, Ca, Mg, S, B, Cu, Fe, Mn and Zn) of hybrid tomatoes (Colibri, Pizzadoro, Debora Max and Granadero), and respective yields of 61 growing areas in greenhouses (24.4 ha) were used. Samples were collected during April to December 2010, in five cities. Five levels of tomato yield (6, 7, 8, 9, and 10 kg plant-1) were used for establishing a database with all binary relationships among all the nutrients studied in all samples. The average, standard deviation and variance for each concentration of nutrient were calculated and it was done for relationship among nutrients, also, in each sub-population. We used 55 relationships which showed the highest ratio in the variance between sub-populations. The nutritional content of each nutrient and the nutrient balance index (IBN) of each production level were calculated. The best correlation between IBN and tomato yield was obtained with 8 kg plant-1 of tomato and this value was defined as an index to be used for DRIS. The nutritional diagnosis carried out in crops with yields below 6 kg plant-1 showed relative deficiencies of K and B and relative excess of Mg.

AbstractLow nutrient use efficiency in maize as a result of imbalanced nutrition has been reported to drastically reduce yield. We implemented a nutrient omission experiment to assess the effect of nutrient application on maize yield and nutritional balance. Maize ear leaves were analyzed for nutrients, to identify nutrient balance status using the Diagnostic and Recommendation Integrated System (DRIS) approach. Results indicated that omission of N or P resulted in highly imbalanced DRIS indices respectively, and significantly lower grain yield. A strong inverse relationship between K ear leaf content with DRIS index suggests that K application negatively increases K imbalance in many situations. Imbalances of Mg, Ca and Cu were more associated with higher yielding treatments. A Which-Won-Where result show that nutrient imbalances in the diagnosis were systematically frequent when N was omitted. All the diagnosed nutrients were imbalanced even under the highest yielding NPKZn treatment; indicating further opportunity for yield increase with more balanced nutrition. Balanced nutrition of maize in the maize belt of Nigeria should target application of varying rates of N, P, K, Mg, S and Zn, depending on the soil conditions. But, because of complexities of nutrient interactions during uptake, it is hardly possible to realize a balanced nutrition. However, differentiating the application of antagonistic nutrients into foliar or soil-based methods is recommended for a more balanced maize nutrition.

Greenhouse-grown cut roses are an economically important and intensive horticultural cropping system receiving large water, fertilizer, agrochemicals, and labor inputs. This study was conducted to establish and validate norms for the nutrient diagnosis techniques Diagnosis and Recommendation Integrated System (DRIS) and Compositional Nutrient Diagnosis (CND) for cut roses (Rosa spp. L.) growing on soil beds within greenhouses in the Bogotá Plateau, Colombia. Information used in this study was obtained from a database of plant tissue and soil analyses, including 1914 foliar analyses of different rose cultivars grafted on the rootstock R. × ‘Natal Briar’. Theoretical validation proved that the generated norms are suitable for crop nutrient status diagnosis, allowing for the correlation of nutrient balance indices with crop flower productivities across a range of cultivars and plant ages. Analysis of the results provided by both DRIS and CND procedures indicated that element relations associated with nitrogen, phosphorous, magnesium, manganese, and boron had a higher influence on the nutritional balance and productivity of roses growing under the conditions of the studied region. In addition, it was preliminarily determined that the use of these diagnostic norms could be extended to rose crops growing under other, and different, rootstocks, production and environmental conditions, and management.

The Diagnosis and Recommendation Integrated System (DRIS) was developed to incorporate the importance of nutrient balance into plant analysis. Yield and plant analysis data from five fertilizer trials conducted in the field during 2 years, using `Granex 33' onions (Allium cepa L.), were entered into a data bank. The trials consisting of a N4 × P4 × K4 × S4, a N4 × P4 × K4 × plant density4, two N4 × P4 × K4, and a 4N × 6S factorial were conducted on sandy Ultisols in Georgia. Significant yield responses resulted from the addition of P and N. Leaf samples were analyzed for N, P, K, S, Ca, Mg, Mn, Zn, Cu, and B. Nutrient data were expressed in ratio form, and the population with yields >45 Mg·ha–1 were used to calculate the DRIS norms. The proposed norms for N, P, K, Mg, and Cu were tested using published data from independently conducted field and greenhouse studies. By accurately diagnosing the most limiting nutrients, these norms successfully predicted yield responses to treatment. Preliminary norms for S, Ca, Mn, Zn, and B were determined but not tested.

ABSTRACT The obtaining of a high banana yield requires that nutrients are in adequate quantities and proportions in the plant. Therefore, the use of methods that encompass nutritional balance and equilibrium is required for a good nutritional evaluation. The objective of this work was to model and determine nutritional and non-nutritional limitations of 'Prata-Anã' banana grown in the states of Ceará (CE) and Bahia (BA), Brazil, based on nutritional balance and equilibrium. The study was developed using the databank of leaf nutrient contents and banana yields of two farms of the Sítio Barreiras company, in Missão Velha (CE) and Ponto Novo (BA), Brazil. The parcels with banana yield above the average plus 0.5 standard deviation; and parcels with banana yield below of that limit were defined as low-yield areas and were used for nutritional diagnosis. The databank was divided into four: the first with 253 samples and a reference population with banana yield above 39.81 Mg ha-1 year-1; the second with 553 samples and a low-yield population (Ceará); the third with 147 samples and a reference population with banana yield above 41.69 Mg ha-1 year-1; and the fourth with 334 samples and a low-yield population (Bahia). Yield limitations in the 'Prata-Anã' banana crops due to nutritional causes reached 13.37% in Ceará, and 12.17% in Bahia. Non-nutritional factors, such as climate and biotic factors, limited the banana crop yields by up to 28.23% in Ceará, and 50.49% in Bahia.

The Diagnosis and Recommendation Integrated System (DRIS) allows the interpretation of results of leaf analysis through relationships among nutrients, instead of the absolute and isolated concentration of each one, as it is used by the criterion of sufficiency range. The objective was to evaluate three procedures of calculation of DRIS indices, and to verify the efficiency of DRIS as interpretation method for the results of Brachiaria decumbens (Signal grass). The study was developed with the results of six experiments carried out in a greenhouse at Piracicaba, SP, with nutrient solution. Concentrations of N, P, K, Ca, Mg, S, Cu, Fe, Mn, and Zn were used in the samples of recently expanded leaf laminae of the grass. The validation of the DRIS method used results from an experiment with nitrogen and sulfur rates applied to the same grass from the Mundo Novo farm, Brotas, SP. DRIS indices were calculated according to two criteria to choose the ratio order of nutrients (F value and R value) and three ways to calculate the nutrient functions (methods of Beaufils, Jones, and Elwali & Gascho). Nutritional Balance Index (NBI), calculated according to the generated norms, presented negative and significant correlation coefficients with the productivity in the combinations of methods tested and DRIS methods proposed by Beaufils, Jones and Elwali & Gascho were efficient in detecting concentrations that show nutrients deficiency or excess.

The objectives of this study were to establish DRIS norms for sugarcane crop, to compare mean yield, foliar nutrient contents and variance of nutrient ratios of low- and high-yielding groups and to compare mean values of nutrient ratios selected as the DRIS norms of low- and high-yielding groups. Leaf samples (analyzed for N, P, K, Ca, Mg, S, Cu, Mn and Zn contents) and respective yields were collected in 126 commercial sugarcane fields in Rio de Janeiro State, Brazil and used to establish DRIS norms for sugarcane. Nearly all nutrient ratios selected as DRIS norms (77.8%) showed statistical differences between mean values of the low- and high-yielding groups. These different nutritional balances between the low- and high-yielding groups indicate that the DRIS norms developed in this paper are reliable. The DRIS norms for micronutrients with high S²l /S²h ratio and low coefficient of variation found can provide more security to evaluate the micronutrient status of sugarcane.

Abstract. Ishthifaiyyah SA, Syukur M, Trikoesoemaningtyas, Maharijaya A. 2021. Agro-morphological traits and harvest period assessment of winged bean (Psophocarpus tetragonolobus) genotypes for pods production. Biodiversitas 22: 1069-1075. Winged bean (Psophocarpus tetragonolobus) is an underutilized crop in Indonesia. Winged bean varieties for pods productions not only must have high productivity and nutrient contents, but also have a long harvest period. This research aimed to evaluate agro-morphological traits and harvest period of eighth-generation winged bean genotypes. Twenty genotypes of winged beans were evaluated using randomized complete block design (RCB) with three replications in Bogor, Indonesia. Several qualitative and quantitative traits were evaluated from each genotype. The results showed that there were variations among winged bean genotypes which were based on qualitative traits as well as the color of stem, calyx, corolla, pod, and pod wings. Purple coloration in the calyx of P1 and H3U genotypes was known to correspond with the purple color in stem, corolla, pod, and pod wings. The highest yield among F8 genotypes was found in H2 (6.69 to ha-1), similar to P2. However, the longest harvest period among F8 genotypes was found in H1U-2 (78 days). This study revealed that harvest period had positive correlation with the leaflet size. Based on nutrient content, H3U and L2 were considered as the genotypes with the highest protein and fiber content respectively among F8 genotypes.
