Abstract: Sugarcane cultivar RB961552 was developed by the Breeding Program of Federal University Alagoas, a member university RIDESA. It selected for being highly productive, responsive to fertigation and high leaf biomass excellent inter-row closure. is resistant brown orange rust moderately scald smut diseases.

The results of experimental studies free-convective heat transfer single-, double- and four-row bundles finned tubes without with an exhaust shaft are presented. It is shown that the inter-tube spacing significantly affects energy efficiency bundle. optimum 61 mm for single-row, about 70 double-row, over bundles. With increase number rows in bundle specific capacity increases, but rate its decr...

Modern agriculture promotes non-inversion, ploughless tillage systems, and simplified plant cultivation methods. Environmentally friendly production technologies must nevertheless guarantee high yields of good quality. In the years 2017/18–2019/20, studies were carried out in which it was assumed that these conditions could be met by strip soil with simultaneous application fertilisers paired-r...

Soil biodiversity is the driving force behind most soil processes. While potentially improving plant productivity and food quality, it can be negatively affected by land use management. Raspberry production part of cultural identity ‘La Comarca Andina’ placed within “Andina Patagonica” world biosphere reserve. In this study we assessed (a) chemical quality (b) microbial in raspberry as manageme...

This paper presents the results of a numerical investigation of the gap influence on the turbine efficiency. The rotor-stator interaction in a 1 2 -stage turbine is simulated by solving the quasithree-dimensional unsteady Euler/Navier-Stokes equations using a parallelized numerical

Several developments and investigations have been done to automate the lateral control of hoes with the aim to achieve higher weeding efficiency and decreased labor costs. The aim of this project was to investigate the accuracy and limitations for a computer controlled hoeing operation based on a GPS system. A conventional hoe and an electro-hydraulic side shift frame was used and attached to a...

In this paper a fuzzy logic navigation controller for an inter-row agricultural robot is developed and evaluated in laboratory settings. The controller receives input from one-dimensional (1D) ranging sensors on the robotic platform, and operated on ten fuzzy rules for basic row-following behavior. The control system was implemented on basic hardware for proof of concept and operated on a commo...
