Abstract Soybean is one of the most important crops in the world and presents great versatility. This study aims to investigate the effect of the Bradyrhizobium japonicum inoculant at 0, 600 and 1200 mL ha1 on soybean crop, with and without 1 L ha-1 calcium (Ca 41%) + 0.4 L ha-1 boron (B 14%). Plants were grown for 90 days in plastic pots with 3 kg of sand and vermiculite (v/v) autoclaved at 121oC for 1 h. The experiment was conducted in a completely randomized design with five replications in a greenhouse. Soybean yield parameters were evaluated, such as, dry weight of shoot, root and total; plant height, nitrogen in the shoot; number and dry weight of nodules; chlorophyll index in the leaves; number of pods per plant (NPPL); number of grains per pod...

Soil fungal and bacterial biomass determined by epifluorescence microscopy and mycorrhizal spore density in different sugarcane managements
Provedor de dados: 65

Crop productivity and sustainability have often been related to soil organic matter and soil microbial biomass, especially because of their role in soil nutrient cycling. This study aimed at measuring fungal and bacterial biomass by epifluorescence microscopy and arbuscular mycorrhizal fungal (AMF) spore density in sugarcane (Saccharum officinarum L.) fields under different managements. We collected soil samples of sugarcane fields managed with or without burning, with or without mechanized harvest, with or without application of vinasse and from nearby riparian native forest. The soil samples were collected at 10cm depth and storage at 4°C until analysis. Fungal biomass varied from 25 to 37µg C g-1 dry soil and bacterial from 178 to 263µg C g-1 dry soil....
