ABSTRACT No-till planting and the use of organomineral fertilizers are crop management practices that increase soil organic matter, thereby mitigating leaching cycling a considerable amount nutrients, with potential to improve yield. This study aimed assess agronomic performance cabbage grown under no-till system, using different cover crops phosphorus sources. A randomized block design was use...

Optimum plant stand density and uniformity is vital in order to maximize corn (Zea mays L.) yield potential. Assessment of can occur shortly after seedlings begin emerge, allowing for timely replant decisions. The conventional methods evaluating an early rely on manual measurement visual observation, which are time consuming, subjective because the small sampling areas used, unable capture fiel...

Incorporation of forest slash during stand establishment is proposed as ameans of increasing soil carbon and nutrient stocks. If effective, the increased soil carbon and nutrient status may result in increased aboveground tree growth. Eight years after study installation, the impact of forest slash incorporation into the soil on soil carbon and nutrient stocks, foliar nutrients and loblolly pin...

Conservation practices such as no-till and cover crops have been shown to on- off-farm benefits. However, when benefits of a practice do not go the provider, underinvestment may occur. Farmland rental arrangements where tenants reap conservation investments are commonly cited barrier adoption in agriculture result lower rates on rented land than owner-operated fields. This issue is especially i...

Black oat (Avena strigosa) is a cover crop with great potential for weed suppression and erosion control while conserving soil moisture. Little known about the of black enhancing food web structure ecosystem services in tropical Oxisols. Two-year field trials were conducted Hawaii to compare three pre-plant treatments: (1) (BO) as followed by no-till practice (previously managed cash rotation c...

The paper presents comparison of three soil tillage systems in maize, winter wheat and soybean growing on anthropogenic Albic Luvisol in north-west Slavonia, Croatia, during 1996-1999. Tillage systems and implements were: 1. conventional system (CT)-plough, disc-harrow and combined implement, 2. conservation system (RT)-chisel plough and multitiller, 3. no-till system (NT). The aim of testing w...

Environ.Entomol.21(2):264-268(1992) ABSTRACT Soybean, Glycine max (L.) Merr., resistance to insects has been shown to vary with planting date and leaf age. This study determined effects soybean genotype, planting date, and leaf age had on feeding behavior of com earworm, Helicoverpa zea (Boddie). Soybean genotypes 'Cobb' (susceptible) and 'GatIR81-296' (resistant) were planted early (29May) and...

Should I switch from conventional till to no-till wheat production? This is one of the most common questions asked by Oklahoma farmers, but it is also one of the most difficult to answer. There are several considerations when making this decision, and there is certainly no one-size-fits-all program for converting from conventional till to no-till wheat production. A few factors to be considered...
