Rhizobial Inoculation and Molybdenum Fertilization in Peanut Crops Grown in a No Tillage System After 20 Years of Pasture

Carlos Alexandre Costa Crusciol, Jayme Ferrari Neto, Tsai Siu Mui, Alan Joseph Franzluebbers, Cláudio Hideo Martins da Costa, Gustavo Spadotti Amaral Castro, [...]


ABSTRACT: Peanut (Arachis hypogea) is an important legume grain consumed by humans and utilized for effective nutrient cycling in a diverse cropping system. Areas that have been cultivated with perennial pasture for decades may have nutritional deficiencies and lack a sufficient population of atmospheric nitrogen-fixing bacteria. Molybdenum is an essential micronutrient that is part of the enzyme nitrogenase contained within symbiotic Bradyrhizobium bacteria, which are responsible for fixing nitrogen in legumes. Our objective was to evaluate the effects of application […]

Macronutrient Uptake and Removal by Upland Rice Cultivars with Different Plant Architecture

Carlos Alexandre Costa Crusciol, Adalton Mazetti Fernandes, Antonio Carlos de Almeida Carmeis, Rita de Cássia Félix Alvarez


ABSTRACT Modern high-yielding rice cultivars possibly take up and remove greater quantities of macronutrients than traditional and intermediate cultivars. This study was carried out with the aim of evaluating the extraction and removal of macronutrients by upland rice cultivars. These information are of utmost importance for the correct fertilizer management. The treatments consisted of three upland rice cultivars (Caiapó, a traditional type; BRS Primavera, an intermediate type; and Maravilha, a modern type). Macronutrient accumulation by rice cultivars up to the […]

Micronutrient and Silicon Uptake and Removal by Upland Rice Cultivars with Different Plant Architecture

Carlos Alexandre Costa Crusciol, Antonio Carlos de Almeida Carmeis, Adalton Mazetti Fernandes, Rita de Cássia Félix Alvarez


ABSTRACT Upland rice cultivars manifest different nutritional demands. A field study was conducted to quantify the extraction, distribution, and removal of micronutrients and silicon by the upland rice cultivars. The experiment was arranged in a randomized complete block-split plot design. Plots consisted of three cultivars (Caiapó – traditional, BRS Primavera – intermediate, and Maravilha – modern) of upland rice. Split-plots consisted of plant samplings, which occurred at 39, 46, 55, 67, 75, 83, 92, 102, 111, 118, and 125 days […]

Autumn Maize Intercropped with Tropical Forages: Crop Residues, Nutrient Cycling, Subsequent Soybean and Soil Quality

Francisco Cézar Belchor Lages Pereira, Luiz Malcolm Mano de Mello, Cristiano Magalhães Pariz, Veridiana Zocoler de Mendonça, Élcio Hiroyoshi Yano, Elka Elice Vasco de Miranda, [...]


ABSTRACT Autumn maize intercropped with tropical forages can raise the amount of crop residues and improve nutrient cycling, favoring subsequent soybean crop. The objective of this study was to evaluate the effect of forms of implementation of intercropping of irrigated autumn maize with tropical forages on yield, decomposition, nutrient accumulation and release, and on the ratio of lignin/total N of forage residues, yield components, and grain yield of subsequent soybean, and on soil physical and chemical properties, under no-tillage in […]

Soil Aggregation, Organic Carbon Concentration, and Soil Bulk Density As Affected by Cover Crop Species in a No-Tillage System

Adriano Stephan Nascente, Yuncong Li, Carlos Alexandre Costa Crusciol


Soil aggregation and the distribution of total organic carbon (TOC) may be affected by soil tillage and cover crops. The objective of this study was to determine the effects of crop rotation with cover crops on soil aggregation, TOC concentration in the soil aggregate fractions, and soil bulk density under a no-tillage system (NTS) and conventional tillage system (CTS, one plowing and two disking). This was a three-year study with cover crop/rice/cover crop/rice rotations in the Brazilian Cerrado. A randomized […]

Effects of surface application of calcium-magnesium silicate and gypsum on soil fertility and sugarcane yield

Carlos Alexandre Costa Crusciol, Rodrigo Foltran, Otavio Bagiotto Rossato, James Mabry McCray, Raffaella Rossetto


Lime application recommendations for amendment of soil acidity in sugarcane were developed with a burnt cane harvesting system in mind. Sugarcane is now harvested in most areas without burning, and lime application for amendment of soil acidity in this system in which the sugarcane crop residue remains on the ground has been carried out without a scientific basis. The aim of this study was to evaluate the changes in soil acidity and stalk and sugar yield with different rates of […]

Nitrogen fertilization (15NH4NO3) of palisadegrass and residual effect on subsequent no-tillage corn

Emerson Borghi, Carlos Alexandre Costa Crusciol, Paulo Cesar Ocheuze Trivelin, Adriano Stephan Nascente, Ciniro Costa, Gustavo Pavan Mateus


Nitrogen is required in large amounts by plants and their dinamics in corn and perennial forages intercropped is little known. This study analyzed the efficiency of nitrogen fertilization (15NH4NO3) applied after corn grain harvest to palisadegrass (Brachiaria brizantha cv. Marandu) in intercrops sown at two times, as well as the N residual effect on the subsequent corn crop. The field experiment was performed in Botucatu, São Paulo State, in southeastern Brazil, on a structured Alfisol under no-tillage. The experiment was […]

Effect of potassium sources and rates on arabica coffee yield, nutrition, and macronutrient export

Mauricio Antonio Cuzato Mancuso, Rogério Peres Soratto, Carlos Alexandre Costa Crusciol, Gustavo Spadotti Amaral Castro


The use of potassium (K) rock powder can be an alternative for K supply of crops. Thus, to reduce K fertilizer imports from abroad, possibilities of extracting this nutrient from Brazilian rocks are being studied. The objective was to evaluate the effect of phonolite rock powder (F2) as K source (Ekosil®) on the air-dried fruit yield, nutrition and macronutrient export of Arabica coffee. The experiment was carried out on a dystroferric Red Latosol (Typic Haplorthox), in Piraju, São Paulo State, […]

Cycling of nutrients and silicon in pigeonpea and pearl millet monoculture and intercropping

Carlos Alexandre Costa Crusciol, Jayme Ferrari Neto, Rogério Peres Soratto, Claudio Hideo Martins da Costa


In a no-tillage system, cover crops must be used that combine shoot dry matter production and nutrient recycling. The aim of this study was to evaluate shoot dry matter production, decomposition rate and macronutrient and silicon release from pigeonpea and pearl millet in monoculture and intercropping systems. A randomized block design was used with a 3 x 6 factorial arrangement, with four replications. The first factor consisted of three cover crops (pigeonpea, pearl millet and intercropping of these cover crops) […]

Upland rice under no-tillage preceded by crops for soil cover and nitrogen fertilization

Edemar Moro, Carlos Alexandre Costa Crusciol, Heitor Cantarella, Adriano Stephan Nascente


The grain yield of upland rice under no-tillage has been unsatisfactory and one reason could be the nitrate/ammonium balance in the soil. Cover crops and nitrogen fertilization can be used to change the nitrate/ammonium relation in the soil and improve conditions for the development of upland rice in the no-tillage (NT) system. The aim was to study the effect of cover crops and nitrogen sources on grain yield of upland rice under no tillage. The study was carried out on […]
