Rice blast is a serious fungal disease of rice (Oryza sativa L.) that threatening global food security. It has been extensively studied due to the importance production and consumption, because its vast distribution destructiveness across world. blast, caused by Pyricularia oryzae Cavara 1892 (A), can infect aboveground tissues plants at any growth stage cause total crop failure. The pathogen produces lesions on leaves (leaf blast), leaf collars (collar culms, culm nodes, panicle neck nodes...
Significance The world has been struggling to find sustainable ways increase crop production satisfy the needs for food, feed, fiber, and industrial uses while reducing negative environmental impacts. This challenge is magnified in countries/regions where availability of farmable land agriculture limited. We developed an integrated cropping system that incorporates key farming tactics. Tested 16 field experiments over 12 consecutive years (2006 2017), increased yields decreasing footprint....
Abstract Better understanding of process controls over nitrous oxide (N 2 O) production in urine-impacted ‘hot spots’ and fertilizer bands is needed to improve mitigation strategies emission models. Following amendment with bovine ( Bos taurus ) urine (Bu) or urea (Ur), we measured inorganic N, pH, N O genes associated nitrification two soils (‘ L ’ ‘ W ’) having similar texture, C C/N ratio. Solution-phase ammonia sl NH 3 was also calculated accounting for non-linear ammonium (NH 4 +...
Corn ( Zea mays L.) grain yield is closely related to plant density and typically maximized in the northern Belt when planting occurs late April. However, spring rainfall events often result wet soil conditions that delay planting. From 2008 2010, experiments were conducted at two locations southern Minnesota determine whether agronomic responses of corn differ with date. Six densities ranging from 38,400 107,900 plants ha −1 evaluated within three dates occurred on 2‐wk intervals beginning...
Cover crops can provide ecological services and improve the resilience of annual cropping systems; however, cover crop use is low in corn ( Zea mays L.)–soybean [ Glycine max (L.) Merr.] rotations upper Midwest due to challenges with establishment. Our objective was compare three planting methods establish (winter rye Secale cereale L. ‘Rymin’], red clover Trifolium pretense ‘Medium’], hairy vetch Vicia villosa Roth], field pennycress Thlaspi arvense ‘MN‐106’], a mixture oat Avena sativa...
Sole biochar addition or microbial inoculation as a soil amendment helps to reduce cadmium (Cd) toxicity in polluted agricultural soils. Yet the synergistic effects of microorganisms and application on Cd absorption plant productivity remain unclear. Therefore, pot experiment was conducted investigate combined effect (Trichoderma harzianum L. Bacillus subtilis L.), (maize straw, cow manure, poultry manure), (0, 10, 30 ppm) physiology growth test how influences nutrient uptake, ameliorates...
Timing and rate of nitrogen (N) fertilizer application can influence maize (Zea mays L.) grain yield, N uptake, use efficiency (NUE) parameters, but results have been inconsistent across the upper Midwest. This study compared single (fall preplant) split applications differing rates for under irrigated conditions on loamy sand at Becker, MN rainfed loam clay soils Lamberton, Waseca, MN, respectively, in 2014 to 2016. Fall preplant were applied recommended 125% (RN) according University...
Nitrogen (N) fertilizers are needed to enhance maize (Zea mays L.) production. Maize plays a major role in the livestock industry, biofuels, and human nutrition. Globally, less than one-half of applied N is recovered by maize. Although application fertilizer can improve yield, excess due low knowledge mechanisms nitrogen use efficiency (NUE) poses serious threats environmental sustainability. Increased consciousness an ever-increasing population necessitate improved utilization strategies...
Sustainable agricultural production is endangered by several ecological factors, such as drought, extreme temperatures, excessive salts, parasitic ailments, and insect pest infestation. These challenging environmental factors may have adverse effects on future agriculture in many countries. In modern agriculture, conventional crop-breeding techniques alone are inadequate for achieving the increasing population’s food demand a sustainable basis. The advancement of molecular genetics related...
The "4R" approach of using the right rate, source, timing, and placement is an accepted framework for increasing crop N use efficiency. However, modifying only one 4R component does not consistently reduce nitrous oxide (NO) emissions. Our objective was to determine if fertilizer applied in three split applications (Sp), by itself or combined with changes source could improve recovery efficiency (NRE) surplus (NS) decrease NO Over two corn ( L.) growing seasons Minnesota, emissions ranged...
Low ambient air temperature limits the growth and selection of crops in cold regions, tolerance is a survival strategy for overwintering plants winters. Studies differences transcriptional levels winter rapeseed (Brassica rapa L.) under stress can improve our understanding transcript-mediated responses. In this study, two varieties, Longyou-7 (cold-tolerant) Lenox (cold-sensitive), were used to reveal morphological, physiological, transcriptome after 24 h stress, at room temperature,...
Modification of N fertilizer application timing within the growing season has potential to reduce soil nitrous oxide (N 2 O) emissions but limited data are available assess its effects. We compared cumulative (cN following urea applied corn ( Zea mays L.) in a single (SA) at planting or three split applications (SpA) over season. For both SA and SpA, granular was broadcast incorporated six rates phase corn–soybean [ Glycine max (L.) Merr.] rotation continuous system two seasons. Daily O flux...
Denitrifying bioreactors can be effective for removing nitrate from agricultural tile drainage; however, questions about cold springtime performance persist. The objective of this study was to improve the removal rate (NRR) denitrifying at warm and temperatures using agriculturally derived media rather than wood chips (WC). Corn (Zea mays L.) cobs (CC), corn stover (CS), barley (Hordeum vulgare straw (BS), WC, CC followed by a compartment WC (CC+WC) were tested in laboratory columns 5 mo...
