Effects of nitrogen application rate on grain yield and grain nitrogen concentration in two maize hybrids with contrasting nitrogen remobilization efficiency
A target in crop production is to simultaneously increase grain yield (GY) and grain nitrogen concentration (GNC). In maize, nitrogen (N) and genotype are two major factors affecting GY and GNC. Both N remobilization from vegetative tissues and post-silking N uptake contribute to grain N, but their relative contributions are genotype specific, and are affected by the N application rate. It is u...


Impact of a woody biochar on properties of a sandy loam soil and spring barley during a two-year field experiment
Biochar is often proposed to increase soil quality and crop yield, while sequestering carbon. Despite the growing number of studies in temperate regions, the claimed positive effects are still unsure for northwestern European soils. Moreover, there is a need to upscale results from lab and pot studies in these soil types to field experiments. The objectives of this study were therefore to inves...
Effect of temperature and precipitation on nitrate leaching from organic cereal cropping systems in Denmark
The effect of variation in seasonal temperature and precipitation on soil water nitrate (NO3 N) concentration and leaching from winter and spring cereals cropping systems was investigated over three consecutive four-year crop rotation cycles from 1997 to 2008 in an organic farming crop rotation experiment in Denmark. Three experimental sites, varying in climate and soil type from coarse sand to...


Assessing nitrate leaching in cropping systems based on integrated weed management using the STICS soil–crop model
Agriculture in Europe and other parts of the world is currently under strong pressure to reduce its reliance on pesticides. Regarding arable crops, strategies based on integrated weed management (IWM) combine several agronomic practices aimed at reducing herbicide use, but these strategies can generate negative collateral effects, such as increased nitrate leaching. An evaluation of nitrate lea...
Effect of depth of fertilizer banded-placement on growth, nutrient uptake and yield of oilseed rape (Brassica napus L.)
A better understanding of crop growth and nutrient uptake responses to the depth of fertilizer banded-placement in the soil is needed if growth and nutrient uptake responses are to be maximized. a two-year field study covering two rape seasons (2010–2011 and 2011–2012) was conducted to examine the effect of banded-placement of N–P–K fertilizer at various depths on growth, nutrient uptak...


Strategic double cropping on Vertisols: A viable rainfed cropping option in the Indian SAT to increase productivity and reduce risk
Our study suggests the possibility for transformational change in the productivity and risk profile of some of India's rainfed cropping systems. In the semi-arid regions of Southern India, farmers traditionally crop sorghum or chickpea on Vertisols during the post-rainy season, keeping the fields fallow during the rainy season. This practice avoids land management problems, but limits the poten...
Using indicators to assess the environmental impacts of wine growing activity: The INDIGO® method
Environmental assessment methods are needed by agronomists working on the enhancement of cropping systems to meet the demand for more sustainable farming practices. A growing number of operational methods based on a set of indicators have been designed, more for arable crops and livestock than for perennial crops like viticulture. Among them, the INDIGO® method, originally developed for arable...

Validity of the pineapple crop model SIMPIÑA across the climatic gradient in Réunion Island
Models used for designing cropping systems and for responding to cropping problems caused by climate variations must generate accurate predictions. Here, we describe the SIMPIÑA model, which simulates the development and growth of the ‘Queen Victoria’ pineapple cultivar and which accounts for stress resulting from nitrogen and water deficiencies. We present the calibration and the validati...
Aquatic hyphomycetes: a potential source of polyunsaturated fatty acids in detritus-based stream food webs
To date, aquatic hyphomycetes have mainly been considered as a source of carbohydrates, mineral elements and proteins for detritivores in detritus-based headwater streams. Yet, consumers are highly dependent on other molecules, such as essential fatty acids, to complete their biological cycle. These molecules might be limiting in detritus-based ecosystems since they are primarily synthesized by...

Biocontrol of gray mold in grapes with the yeast Hanseniaspora uvarum alone and in combination with salicylic acid or sodium bicarbonate
The yeast Hanseniaspora uvarum alone or in combination with salicylic acid or sodium bicarbonate was investigated for control of gray mold, postharvest quality and antioxidant enzymes of grapes. The results indicated that the treatment of H. uvarum suspension of 1×108 CFUmL−1 combined with either 2mmolL−1 SA or 2% SBC resulted in a remarkably improved control of Botrytis cinerea infections...

Effects of 1-methylcyclopropene in combination with chitosan oligosaccharides on post-harvest quality of aprium fruits
Aprium (Prunus armeniaca × salicina L. cv. Xingmei) fruits were treated with 1.0μL/L 1-methylcyclopropene (1-MCP) for 12h at 20°C or dipped for 2min into 0.5% (w/v) chitosan oligosaccharides (COS) solution, or treated with the combination of the both, then stored at 2°C for up to 30 days. Aprium fruits exhibited a typical climacteric pattern in ethylene production and respiration rate. Trea...
Modelling the Effects of Soil Conditions on Olive Productivity in Mediterranean Hilly Areas
The majority of olive (Olea europaea L.) production in Mediterranean environments is characterized by low external inputs and is practiced in hilly areas with shallow soils. This study aimed to study the yield and nutritional status for olive (cv. “Zeiti”) trees in northwestern Syria and establish correlations between yield, on the one hand, and soil/land factors and tree nutrition, on the ...
Effect of Butylated Hydroxytoluene (BHT) on the Cryopreservation of Common Carp (Cyprinus carpio) Spermatozoa
The aim of the present study was to test the effects of butylated hydroxytoluene (BHT) on the cryopreservation of common carp spermatozoa. BHT is widely used in the cryopreservation of the spermatozoa of different animal species and successfully sustains the characteristics of spermatozoa during freezing and thawing, but it has not previously been used with fish. After sampling, common carp spe...
Role of body condition score and body weight in the control of seasonal reproduction in Blanca Andaluza goats
The reproductive activity of 84 female Blanca Andaluza goats was monitored over 17 months to determine the role of body condition score (BCS) and body weight (BW) in its control. Following a 3×2 factorial experimental design, the animals were allocated to three groups: low BCS (≤2.50, n =24), medium BCS (BCS=2.75-3.00, n=31) and high BCS (≥3.25, n =29). The same animals, irrespective of th...
