Intensive tillage-based production systems coupled with inefficient fertilizer management practices have led to increased costs, sub-optimal productivity, and significant environmental externalities. Conservation agriculture (CA) is being increasingly advocated as a strategy overcome these issues but precision nutrient under the CA-based maize-wheat system rarely studied. Two year’s (2014–2015 ...

-promoters include control of zoonotic pathogens i. Antibiotic growth promoters enhance the efficiency of nutrient resistance in pathogenic bacteria and it has -promoters imposes a selection pressure for bacteria that are resistant to continued use of antimicrobial

The digestibility of amino acids and other nutrients by the pig is an important measure of efficiency when evaluating swine diets or ingredients used in swine diets. Any method of feeding or use of a feed additive that significantly increases the ileal digestibility of amino acids could be used to increase the efficiency of amino acid use by the pig, and decrease waste and nutrient losses from ...

population growth as well as global fresh water shortage problem have necessitated the use of unconventional water resources in agricultural sector, as the largest consumer of fresh water, especially in arid and semi-arid regions. in this study, the effect of four irrigation methods on yield, uptake of water and important nutrients, and the salt accumulation in soil was investigated using a com...

Abstract: The objective of this work was to evaluate phytomass production, nutrient cycling, and efficiency use by single intercropped crop systems, in the second crop, under no-tillage. experiment carried out during 2014 2015 Cerrado biome state Mato Grosso, Brazil, a randomized complete block design, with nine treatments four replicates. In 2014, systems were evaluated at 63, 93, 124, 157 day...
