Irrigation and Drainage, EarlyView.ABSTRACT There is limited integrated evaluation of nitrogen (N) and irrigation management strategies for improving maize yield and productivity using crop models. The effects of N and irrigation on maize yield and productivity under centre pivot (CPI) and subsurface drip irrigation (SDI) using the CERES‐Maize model were investigated. N treatments were (

Turning Down Mum's Cooking: The Ethics of Dietary Difference within Families
Journal of Applied Philosophy, EarlyView.ABSTRACT Although food ethicists have called for greater attention to the relational context of eating for over a decade, the context of ‘eating with family’ remains largely ignored. But the family is both a morally specific relational context and one within which many people do most of their eating.

WEED CONTROL EFFECTS ON SOIL CHEMICAL CHARACTERISTICS
Revista Caatinga, 2008 The weed control procedures are known to affect the soil physical attributes and the nutrient amount taken up by weed roots. This work hypothesis is that weed control methods might also affect soil chemical attributes.

Procedures of image analysis for weed recognition in cereals [PDF]
, 2012 An automatic weed recognition system is a prerequisite for site specific weed control when using weed threshold concepts. Segmentation, a preprocessing step, is applied to two- or three-dimensional images. In the following step, methods of graph matching,

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background: Grass–clover and silage maize are key for dairy feed production and frequently occur within the same crop rotations. Fertilizer management in grass–clover may leave residual effects that influence both environmental outcomes and the performance of subsequent maize crops.

Reducing weed infestation in winter wheat by sowing technique
, 2007 Hoeing can improve weed control in cereals but this requires wider row spacing of the crop. A spe-cific band row design may also ensure high crop yield and quality, especially at the conditions of organic farming.

Organic Matter Quality and Microbial Activity in Soils Managed With Brachiaria Succession
Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background Although succession systems and brachiaria improve soil quality, gaps remain in microbial community dynamics, activity, and soil organic matter stocks. Methods The objective was to evaluate the carbon (C) and nitrogen (N) stocks of soil organic matter fractions and their distribution, molecular characterization, enzyme activity ...

Journal of Plant Nutrition and Soil Science, EarlyView.ABSTRACT Background and aim Conservation agriculture (CA) is rapidly gaining traction to promote sustainable crop production, focusing on minimum soil disturbance, permanent soil cover, and strategic crop rotation. Moreover, hydrogel is increasingly being used to improve water retention, including in combination with CA, particularly in water limited ...
