1. Selection and recommend of quinoa (Chenopodium quinoa) genotypes based on the yield genotypic adaptability and stability
ABSTRACT The present study aimed to select and recommend quinoa genotypes based on the yield genotypic adaptability and stability, by the method of the Harmonic mean of relative performance of genotypic values. Five experiments were conducted during the crop seasons of 2014 and 2015 in two locations in the Western region of Paraná State, Brazil. This study

2. Modelo Penman-FAO ajustado para a estimativa da necessidade hídrica do feijão no Cerrado.
ABSTRACT: Bean crop producers from the Brazilian Cerrado region have only one technology adjusted for irrigation management which consist in the measurement of soil-water tension through the use of tensiometers. Although this methodology has high potential of use, it has not been widely adopted by the producers due to problems in instrumentation maintenance.

3. Sugarcane crop efficiency in two growing seasons in São Paulo State, Brazil.
A conceptual framework for crop production efficiency was derived using thermodynamic efficiency concept, in order to generate a tool for performance evaluation of agricultural systems and to quantify the interference of determining factors on this performance. In Thermodynamics, efficiency is the ratio between the output and input of energy. To establish th

4. Performance of the AquaCrop model for the wheat crop in the subtropical zone in Southern Brazil
Resumo: O objetivo deste trabalho foi calibrar e validar o modelo AquaCrop para a cultura de trigo (Triticum aestivum) na região dos Campos Gerais, no Sul do Brasil. Foram avaliadas cinco cultivares nas safras de 2007 a 2017. Os dados de entrada no AquaCrop - referentes a clima, cultura, solo e manejo do solo -, coletados em campo, foram obtidos do banco de

6. Doses of caffeine on the development and performance of pepper crops under greenhouse
A number of experiments on plant organs demonstrated that caffeine acts as a growth stimulator. In this study we aimed to determine the influence of caffeine on development of pepper crops under stress in the autumn-winter cycle, as peppers stop growing and developing in November and January. The experiments were conducted to determine how caffeine applied t

7. PERFORMANCE OF CORN SOWING IN FERTILIZATION SYSTEM AND INTERCROPPING
ABSTRACT The performance of the tractor-seeder can be influenced by factors related to the seeder, as loads and crop. The aim of the present study was to evaluate the performance of tractor-seeder at sowing in the corn crop in function of the fertilizer systems (at presowing and at sowing) and those intercropping of crops (corn + bean-Stizolobium deeringianu

9. Efficiency of the predatory mite Phytoseiulus macropilis (Banks) (Acari: Phytoseiidae) in the control of Tetranychus urticae Koch (Acari: Tetranychidae) in tomato crop / Eficiência do ácaro predador Phytoseiulus macropilis (Banks) (Acari:Phytoseiidae) no controle de Tetranychus urticae (Koch) (Acari: Tetranychidae) em tomateiro
Tomato (Solanum esculentum Dunal) is the most important industrialized vegetable crop in the world and the second in terms of cultivated area. This crop presents serious phytosanitary problems during its entire cycle and, among the main pests of the tomato plants, Tetranychus uticae Koch is considered one of the most important phytophagous mite in the whole

10. Performance of super hybrid rice cultivars grown under no-tillage and direct seeding
Good progress has been made in the super hybrid rice (Oryza sativa L.) breeding in China. However, rice yield not only depends on the genetic characteristics but also on the agronomic practices. No-tillage and direct seeding (NTDS) is a simplified cultivation technology that greatly simplifies both land preparation and crop establishment. Aiming to determine

11. Agronomic performance and genetic dissimilarity of second-harvest soybean cultivars using REML/BLUP and Gower’s algorithm
ABSTRACT The cultivation of second-harvest with soybean crop after first-harvest with maize crop has become an alternative to aggregate income to farmers in the South region of Brazil. However, there is little information about this cropping system in this region. The aims of this study were to: (i) evaluate the agronomic performance of soybean (Glycine max

12. Diagnosis of the Nutritional Status of Garlic Crops
ABSTRACT Univariate methods for diagnosing nutritional status such as the sufficiency range and the critical level for garlic crops are very susceptible to the effects of dilution and accumulation of nutrients. Therefore, this study aimed to establish bivariate and multivariate norms for this crop using the Diagnosis and Recommendation Integrated System (DRI
