This study was aimed at enhancing the production of xylanase from an alkaliphilic Bacillus pumilus VLK-1 in submerged fermentation using wheat bran, a cheap and abundantly available agro-residue, through process optimization and to monitor the effect of temperature shift operation on it. The potential of xylanase in saccharification of wheat straw was also investigated. The results showed that ...

ABSTRACT Strain L324-92 is a novel Bacillus sp. with biological activity against three root diseases of wheat, namely take-all caused by Gaeumannomyces graminis var. tritici, Rhizoctonia root rot caused by Rhizoctonia solani AG8, and Pythium root rot caused mainly by Pythium irregulare and P. ultimum, that exhibits broad-spectrum inhibitory activity and grows at temperatures from 4 to 40 degree...

Herbicide resistance in weeds is a global threat to sustaining food security. In India, herbicide-resistant Phalaris minor was the major problem wheat for more than two decades, but continuous use of metsulfuron-methyl (an ALS inhibitor) control broadleaf has resulted evolution inhibitor-resistant Rumex dentatus L. This review summarizes current scenario herbicide R. dentatus, along with its ec...

Bacterial communities are important not only in the cycling of organic compounds but also in maintaining ecosystems. Specific bacterial groups can be affected as a result of changes in environmental conditions caused by human activities, such as agricultural practices. The aim of this study was to analyze the effects of different forms of tillage and residue management on soil bacterial communi...

Irrigated crops are produced on 645,000 ha in east-central Washington and northcentral Oregon (1). Approximately 70% of this cropland is irrigated with water diverted from rivers, while water for the remaining hectares is pumped from deep wells. Much of the irrigated cropland is found in areas of less than 200 mm annual precipitation, where dryland farming is difficult or impossible. Wind erosi...

The study examines reasons for the burning of crop residue, awareness impact and government approaches to mitigating burning. Data from 180 farmers three districts state Haryana was sought. Rank Based Quotient method used identify reasons. At same time, assessed by direct questioning. concludes that short window time between paddy harvesting showing wheat a primary reason stubble Research also ...

Wheat is grown in an area totalling 31.1 million hectares India. The North-western Indo-Gangetic Plains (IGP) constitutes the major share of and production wheat India known as belt However, sustaining under declining/lower resource-use efficiency existing rice–wheat cropping system has led to considerations about diversifying this with a pigeon pea–wheat (PWS) IGP little or no information avai...

abstract soil microbial activity and biochemical processes are often limited by carbon availability in arid- and semi-arid regions, probably due to the low organic matter content. consequently, return of plant residues to soil is a convenient and effortless practice for increasing microbial activities and biochemical reactions. the primary objective of this study was to evaluate the effect of v...

Sustainable management practices are needed to enhance soil productivity in degraded dryland soils in the northern Great Plains. We examined the effects of two tillage practices [conventional till (CT) and no-till (NT)], five crop rotations [continuous spring wheat (Triticum aestivum L.) (CW), spring wheat-fallow (W-F), spring wheat-lentil (Lens culinaris Medic.) (W-L), spring wheat-spring whea...

Glu-1Ay, one of six genes encoding a high molecular weight glutenin subunit (HMW-GS), is frequently silenced in hexaploid common wheat. Here, an active allele of Glu-1Ay was integrated from wild emmer wheat (Triticum turgidum ssp. dicoccoides) accession D97 into the common wheat (Triticum aestivum) cultivar Chuannong 16 via the repeated self-fertilization of the pentaploid interspecific hybrid,...
