Corn Response as Affected by Planting Distance from the Center of Strip-Till Fertilized Rows

Abstract

Strip-till has been used at a large scale in east central Kansas as an alternative to earlier planting dates under a no-till system. To determine the effects of planting corn (Zea mays) under previously established strip-tilled fertilized rows, experiments were conducted on an Osage silty clay loam soil in 2006 and 2008 and on a Woodson silt loam soil in 2009, 2010, and 2011 using three different planting distances from the strip-tilled fertilized rows (0, 10, 20, and 38 cm) with a strip-till operation performed between 1 and 73 days before planting. The depth of the strip-till fertilizer application was 13–15 cm below the soil surface. Corn that was planted 10 cm from the fertilized row showed greater early season growth, higher plant population, and grain yield. Planting 20 and 38 cm from the center of the fertilized rows showed none of the benefits that are typically associated with strip-tillage system. Enough time should be allowed between the strip-till operation and planting to reach satisfactory soil conditions (e.g., moist and firm seedbed). Our results suggest that the best location for planting strip-tilled fertilized corn vary depending on soil and climatic conditions as well as the time between fertilizer application with the strip-till operation and planting. With fewer number of days, planting directly on the center of fertilized strip-till resulted in decreased plant population and lower grain yield. However, the greatest yield benefit across different planting conditions was attained when planting within 10 cm of the strip.

Mineral Composition and Baking Value of the Winter Wheat Grain under Varied Environmental and Agronomic Conditions

“…With that technology, the first rate of fertilisers is applied only into rows, localised fertilisation, and not into the entire space of the soil under tillage. Localised fertilisation results in a greater concentration of nutrients in the neighbourhood of plants and their better nutrition [43]. A variable environment and the agronomic treatments did not have a significant effect on the ash content in flour, although Alijošius et al [44] point to a high variation in that trait.…”

Phosphorus Fertilizer Placement and Tillage Affect Soybean Root Growth and Drought Tolerance

“…N o-till system (NT) can provide substantial improvements in physical, chemical, and biological soil characteristics, reducing nutrient loss and soil erosion, as well as increasing soil organic matter and soil water retention Bolliger et al, 2006). However, the low soil disturbance associated with NT can result in higher nutrient concentration near the soil surface (stratifi cation), especially for immobile nutrients such as P (Howard et al, 1999;Adee et al, 2016;da Costa and Crusciol, 2016). Stratifi cation of nutrients can aff ect plant root growth and therefore impact plant response to soil moisture and precipitation conditions.…”

“…On the other hand, band application of P fertilizer can contribute to reduce potential P fixation in Oxisol soils (Balastreire and Coelho, 2000) increasing P availability to the root system (Shen et al, 2011). Furthermore, the combination of P fertilizer placement and some level of tillage such as strip-tillage may provide benefits under some specific production conditions (Adee et al, 2016).…”

Deep Banding Increases Phosphorus Removal by Soybean Grown under No‐Tillage Production Systems

“…Th erefore, P management practices that enhance root system access to the nutrient can play an important role to improving P acquisition , and support yield potentials (Adee et al, 2016).…”
