Eficiencia de solubilización de fósforo de aislados nativos guatemaltecos de Pseudomonas fluorescens

El fósforo (P) es un elemento esencial en la producción agrícola, pero debido a su compleja dinámica en el suelo, solo una pequeña cantidad es aprovechable para las plantas, ya que la mayoría del P se encuentra en formas insolubles, especialmente, en suelos Andisoles de origen volcánico. Los micro...

Prediction of Land Suitability for Crop Cultivation Using Classification Techniques

Abstract Agriculture, the backbone of every country, has been an emerging field of research, particularly in the recent past. The soil type and environment are critical factors that drive agriculture, especially in terms of crop prediction. To determine which crops grow best in certain types of soil and ...

Economic study of the cultivation of kale, coriander, lettuce, and chives in intercropping

Biosci. j. (Online); 36 (Supplement1), 2020
Intercropping of vegetables in a poorly planned manner may not achieve the expected economic results, as it is an activity that requires a great technical and administrative capacity of the producer. This study aimed to analyze the economic feasibility of intercropping kale with coriander, lettuce, and c...

Canola agronomic performance in three sowing dates in Jataí-GO

Biosci. j. (Online); 36 (Supplement1), 2020
Canola (Brassica napus L. var oleifera) is a potential crop due to the growing world demand for vegetable oil. This work aims to evaluate the performance of five canola hybrids in three sowing dates in Jataí-GO. The experiment was conducted in the year of 2017, in a randomized block design, with subdivi...
