Effects of irrigated cover crop cultivation period on common bean and soybean yield
Abstract Cover crop inclusion is essential for improving soil management in tropical no till systems; however, the optimal duration of irrigated off‐season cultivation remains uncertain. This 3‐year field study evaluated nine cover crop species or mixtures and four cultivation periods (60, 75, 90, and 105 days) on biomass production, soil chemical ...

Abstract Establishing forage in loblolly pine (Pinus taeda L.) plantations has the potential to increase grazing acreage for cattle farms in the Mid‐South, but appropriate species selection still requires investigation. The objective was to evaluate forage mass, accumulation, and nutritive value of four perennial forage species, novel‐endophyte tall ...

Numbers of weed seedbank in maize field crop [PDF]
A large seed production and the efficient propagation ensure the survival of weeds. After spreading most of the seed reaches the soil, and therefore weed seedbank are the main source of weed.

Corn tolerance and weed control with amicarbazone and metribuzin applied preemergence
Abstract Since the late 1950s, atrazine has been a cornerstone of corn (Zea mays L.) weed control, but decades of use have raised concerns about groundwater contamination and enhanced biodegradation. Therefore, amicarbazone and metribuzin were evaluated as alternatives to preemergence use of atrazine in corn.

Cover crop and termination date effects on wheat forage biomass, nutrient content, and profitability
Abstract Cover crops are being encouraged due to benefits to soil health and ecosystem services, but they could negatively affect subsequent forage production and system profitability in regions with limited water availability. The objectives of this study were to determine the effects of cover crop treatment and termination date on wheat (Triticum ...
