Available in PDF, EPUB and Kindle. Book excerpt: Effective weed control is one of the most yield-limiting factors in organic corn and soybean production. Additionally, the amount of tillage needed to control weeds in organic practice is often criticized for its negative impacts on soil quality. This research was conducted in central Missouri from 2016-2017 to compare cultivation, flame application, between-row mowing, and hot water spray for in-season weed control in organic corn and soybeans. Between-row mowing and hot water application were paired with notillage and a crimped winter cover crop of cereal rye (Secale cereale L.). When weeds reached 10.2 cm, weed control practices were implemented and repeated as necessary until canopy closure. Grass and broadleaf weed biomass between crop rows was determined at multiple dates throughout the 2016 and 2017 seasons and in-row weed levels were determined at the final collection date for each crop each year. Broadleaf weed biomass at the end of the soybean season in 2016 was lower in the two treatments utilizing no-till and cover crops as primary weed control and hot water and mowing as secondary control. Soybean yield was adversely affected by flaming but not significantly different for the cultivation, mowing and hot water treatments. In 2017, soybean had less between-row grass biomass in the cultivation and flaming treatments than in hot water and mowing, but broadleaf levels were the same in the mowed treatment as the cultivated and flamed treatments. In 2016, grass biomass was lower in the no-till treatments between corn rows and higher in the crop rows than the other two treatments. Weed control treatments led to no significant differences in corn yield in 2016 and higher yields in the no-till treatments in 2017. In-row weed levels were significantly higher in corn in 2017 for the hot water treatment. Hot water at the levels applied in this research was not an effective weed control method. Since the overuse of cultivation can decrease soil organic matter levels and increase soil erosion, alternatives techniques are important to grant farmers the possibility to use their land for a long time. The crimped cover crop used in the no-till treatments limited weed growth in early-season corn and soybean and when coupled with between-row mowing is a potential alternative to cultivation in organic crop production. Flaming is also a potential alternative to cultivation in corn production.
Download or read book Weed Control in No till Organic Soybean in Southern Brazil written by Carlos Armenio Khatounian and published by . This book was released on 2004 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Organic soybean production is a fast growing enterprise in southern Brazil, particularly in the state of Parana where 854 farmers harvested 48,000 metric tons in 2002, 11 times more than in 1997; however, the expansion of organic soybean production is hindered by the difficulty to control weeds, particularly in no-till organic fields. Brachiaria plantaginea is the most deleterious in the region. To facilitate control of this weed in organic no-till systems, seven experiments were conducted and a simulation model was developed. The experiments addressed the suppressive effect of black oat (Avena strigosa) mulch on the emergence of B. plantaginea, and weed seed and biomass production in different crop environments and emergence times. Potential strategies for more effective weed control were examined with the simulation model. Increasing black oat mulch from 0 to 10 Mt/ha reduced the population density of B. plantaginea exponentially. By reducing weed density, increasing mulch quantity increased soybean biomass and yield. Substantial reductions in weed population density required mulch quantities at or above 6 Mt/ha. Increasing mulch also decreased weed seed production exponentially, although weed seed production always remained above 1,000 seeds/m2, which is high enough to support heavy infestation in subsequent crops. In association with maize, the weed caused a loss in crop yield of at least 80% when no weed control was applied. When the crop was kept free of weeds for at least 20 days after planting, crop yield was not affected. Weed seed production in the maize stand decreased exponentially as the weed-free period increased from 0 to 60 days, counted from the crop planting. Without control, the weed produced up to 7,000 seeds/m2. Weed plants that emerged after the 40-day weed-free period produced, at the very most, 50 seeds/m2. Seed production of pure weed stands ranged between 9,000 and 47,000 seeds/m2, and was always greater than weed seed production in adjacent soybean or maize stands. Modeling indicated that alternating seasons of heavy mulch with seasons of low mulch combined with strict weed control may be a more effective strategy than continuous heavy mulch to keep low weed populations.

This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fall herbicide applications have increased in popularity in recent years. Little is known of how fall herbicide applications impact soil conditions, insect populations, and winter and summer annual weed populations. Few studies have directly compared fall herbicide applications to early spring applications. Therefore, field experiments were conducted in both no-till corn and soybean fields from 2004 through 2006 in central, northwest, and northeast Missouri. Herbicide applications were made in the fall and at three spring timings. Two residual and one non-residual herbicide treatment were applied at each of the four timings. Removal of winter annual weeds with the three herbicide treatments led to an increase in soil moisture just after planting, and a decrease in insect populations and feeding well after planting. Measurements of soil temperature indicated that removing winter annual weeds could increase temperatures in the spring. Fall residual herbicide treatments provided the highest level of winter annual weed control, yet provided poor control of summer annual weed species after planting. Residual herbicide applications made at the last spring timing provided the highest level of summer annual weed control, yet provided poor winter annual weed control at planting. Residual herbicide applications made one to two months prior to planting offered the best balance between winter and summer annual weed control. Based on the results of these experiments, no-till corn and soybean producers can obtain maximum weed control and planting conditions by applying a residual herbicide in the early spring rather than the.

Download or read book Integrating Cover Crops in No till Corn and Soybean to Diversify Herbicide Resistant Weed Management in the Mid Atlantic written by Jess Marie Bunchek and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Widespread adoption of genetically-engineered, herbicide-resistant (HR) crops have simplified crop rotation diversity and the use of single-tactic, herbicide-based weed management programs. These practices have resulted in an HR weed epidemic, where glyphosate-resistant weeds are especially problematic. Glyphosate-resistant weeds like horseweed [Conyza canadensis (L.)] and pigweeds (Amaranthus spp.) threaten grower productivity and long-term efficacy of common agronomic herbicides. Thus, integrated weed management (IWM) programs that implement both ecological- and herbicide-based tactics are needed in no-till annual grain systems to (1) manage current HR weeds, (2) reduce HR selection pressure for evolution of resistance to other herbicides, (3) preserve effective herbicide technology, (4) enhance environmental stewardship, (5) safeguard soil conservation gains, and (6) maintain farm profits and productivity. To address these goals, we established three field studies at two sites in the Mid-Atlantic and identified combinations of cover crop and herbicide tactics that achieve effective season-long annual weed management, minimize HR selection pressure, and increase sustainability by reducing herbicide inputs. The first two studies assessed the complementarity of cover crops treatments and herbicide programs in corn and soybean, where integrating a cover crop treatment combined with applying a spring, pre-plant burndown herbicide application as well as a POST-emergent application provided the most effective season-long annual weed control. The third study assessed cover crop treatments and varied management practices, such as planting and termination dates, on HR selection pressure reduction at the time of herbicide applications. While cover crops intercepted a portion of the burndown herbicide application from reaching the soil surface, weeds were effectively controlled by the cover crops before the application, thus reducing the HR selection pressure.
