The present study reveals that a potent laccases producer Pycnoporus cinnabarinus produces higher quantity of laccases in the Coll et al. Medium (M1 medium) and Potato dextrose broth medium (M4 medium) containing agricultural waste ‘wheat bran’ (1%w/v) after a great comparative study among the five laccases production media namely Coll et al. medium (M1 medium), Olga et al. medium (M2 medium), ...

Abstract Aims The home-field advantage (HFA) hypothesis predicts faster decomposition of plant residues in home soil compared to soils with different plants ( away ), and has been demonstrated forest grassland ecosystems. It remains unclear if this legacy effect applies crop residue arable rotations. Such knowledge could improve our understanding dynamics may allow optimisation amendments syste...

A microplot experiment was conducted in soybean–wheat cropping system at New Delhi during 2010-11 and 2011-12 to study the effect of continuous or cyclic tillage, viz., conventional tillage (CT) and zero-tillage (ZT) and residue management of either soybean (SR) and/or wheat (WR) on yield performance and soil physico-chemical properties. The experiment was laid out in randomized block desi...

This study setout to investigate the effect of wheat residue, tillage, and nitrogen fertilizer management on some agronomic traits of soybean as a split split plot based on randomized complete block design with three replications. The main plots included wheat residue management: collecting and leaving residue and sub plot included tillage (without tillage and conventional tillage), and the sub...

Chlorpyrifos, a widely used organophosphorus insecticide having many urban and agricultural pest control uses, is one of the major pesticides detected in Taiwan fishery products. Whereas previous studies examined, this study explored possible sources of chlorpyrifos residue, particularly in farmed fish. Eight hundred fourteen samples of marketable fish were analyzed for chlorpyrifos residues. O...

Eastern forests of the US are valued both as a carbon sink and a wood resource. The amount of biomass that can be harvested sustainably from this biome for bioenergy without compromising the carbon sink is uncertain. Using past literature and previously validated models, we assessed four scenarios of biomass harvest in the eastern US: partial harvests of mixed hardwood forests, pine plantation ...

Many people consider earthworms to be an indicator of soil quality because they respond to and contribute to healthy soil. For earthworms to be abundant, a field must meet several conditions that are also associated with soil quality and agricultural sustainability: moderate pH, surface residue for food and protection, and soil that is not waterlogged, compacted, droughty, or excessively sandy....

The objective of this study was to determine the drying behavior of 2-phase olive mill waste (2POMW) under isothermal microwave-convection drying conditions. 2POMW samples were dried in a thin layer in a variable-power pilot microwave oven with impinging air, using a feedback controller to maintain sample temperature at one of four levels. Moisture loss and shrinkage of the samples were recorde...

Living and dead plant vegetation on the surface of soils can provide opportunities for regulating pest populations in no-tillage production systems. Cover crops generate substantial quantities of surface vegetation and residue that can be managed to enhance control of pests. Research at the Beltsville Agricultural Research Center has shown that weed germination and emergence is inhibited by hig...
