ABSTRACT Cestrum parqui is a perennial plant known for its toxicity in ruminants. This work describes several outbreaks of natural intoxication with C. parqui from different sources, affecting cattle in different production systems, with morbidity rates varying from 2,7% and 25%. Clinical signs included tremors in the hindquarters, recumbency, and death. The liver showed swelling, […]

ABSTRACT The calculation of volume of different oilseed grains through computational models has demonstrated its effectiveness and efficiency. In the present work, the model has been extended to allow calculations of the soybean volume. The model proposes that each grain of the sample is assimilated to a parallelepiped with main axes L (length), W (width) […]

ABSTRACT We conducted four experiments to evaluate the effects of different heights and times of pruning on the growth of Eucalyptus grandis and E. grandis x E. camaldulensis GC INTA 8 in Concordia (Entre Ríos, Argentina). During winter, two experiments were carried out on 20 months old stands and, during spring, two more experiments were […]

ABSTRACT Tomato spotted wilt orthotospovirus (TSWV) causes important economic losses in potato production. The cultivar Innovator is the most widely used variety for potato industrial processing and the second most extensively grown cultivar in Argentina. The objective of this study was to identify the most suitable tissue sample for TSWV detection in potato cv. Innovator […]

ABSTRACT The theoretical framework of Complex Adaptive Systems allows modeling human-environment interactions that are constantly evolving and have implications for sustainability. The aim of this paper is to identify which approach, Malthusian or Boserupian, has served as a reference in contemporary studies on the human-environment relationship. We carried out a systematic review of the scientific […]

Yield prediction is still a major challenge in pear production. Forecasting fruit growth after modeled curves allows predicting both potential yield and quality. This research aimed to fit multilevel no-linear mixed models (NLMM) based on logistic curves to describe pear growth in the Upper valley of Rio Negro and Neuquén, Argentina. The models incorporated several […]
