“…Soybean is a basic raw material whose processing gives rise to crude oil and meal. The processing of these primary products allows obtaining a series of secondary products, which are used as industrial inputs in several other processing lines, thus enabling a series of use options for soybean (HEIFFIG-DEL AGUILA et al, 2020).…”

The possibility of early soybean fertilization carried out on the predecessor crop has several benefits, mainly operational ones, making the production system more conservationist and balanced. An experiment was carried out at the Anhumas Experimental Station, Luiz de Queiroz College of Agriculture (USP/ESALQ), located in Piracicaba, SP, Brazil, during 2001/2002, 2002/2003, and 2003/2004 agricultural years on a typic Hapludox aiming to evaluate the effects of the early fertilization on soybean yield. The fertilization consisted of applying 90 kg ha−1 of P2O5, 50 kg ha−1 of K2O, and micronutrients (Co, Cu, Fe, Mn, Mo, and Zn). The experiment was conducted in a randomized complete block design with three replications and 12 treatments consisting of different levels of early soybean fertilization carried out on the finger millet crop: T1, no fertilization; T2, conventional soybean fertilization; T3, early 50% K fertilization; T4, early 100% K fertilization; T5, early 50% P fertilization; T6, early 50% P and K fertilization; T7, early 50% P and 100% K fertilization; T8, early 100% P fertilization; T9, early 100% P and 50% K fertilization; T10, early 100% P and K fertilization; T11, early 100% P and K fertilization + micronutrients; and T12, early leaf fertilization with micronutrients. The results showed that the early soybean sowing fertilization with phosphorus and potassium carried out during finger millet sowing does not interfere with the thousand-seed weight and soybean yield.

“…These cultivars are positioned through soybean macroregions in Brazil, called South, Center-South, Southeast, Central-West and North/Northeast. In which, each is subdivided into 20 edaphoclimatic microregions (Aguila et al, 2020). This subdivision aims to group the cultivars according to their characteristics weighted by the peculiarities of the growing environment, based on latitude, temperatures and rainfall, photoperiod and soil classification.…”

This study aimed to assess genetic dissimilarity and based on the qualitative and quantitative characteristics of 52 soybean cultivars grown in the Northwest Region of the state of Rio Grande do Sul. The experiment was conducted at the Center for Research and Agronomic Results of the Missions (CEPRAM). The experimental design used was randomized blocks with treatments arranged in four replications. Soybean qualitative attributes were measured, being the maturity group, flower color, pod color, seed shape, tegument color, anthocyanin pigmentation in the hypocotyl, pubescence color, pubescence density, hilum color, seed brightness and biotechnological event. Together, quantitative attributes were measured in ten plants per experimental unit, such as yield, number of pods per plant, number of grains per plant, grain mass per plant and thousand seed mass. The most productive cultivars were P95R90 IPRO, BMX Raio IPRO, NS 5445 IPRO, P95R30 IPRO, P95Y02 IPRO, TMG 7058 IPRO and DM 5958 IPRO. Yield correlates positively with the number of pods, number of grains, grain mass and thousand seed mass. The dendrogram for the quantitative characteristics and the decision tree showed that the formation of the groups and the grain yield were determined mainly by the grain mass and the thousand seed mass. Among the components of variance and genetic parameters, the variables thousand grain mass, grain mass and yield are influenced by 59%, 32% and 29% respectively by genetic effects.
