“…The lowest average grain yield at Mochełek (3.95 t ha −1 ) was associated with the lowest amounts of nitrogen (80 kgha −1 ) and phosphorus fertilization (17 kgha −1 every year), and the highest average grain yield at Sobiejuchy (8.08 tha −1 ) with additional potassium. The latter observation supports findings of Snyder and Mascagni (1998) and Sweeney et al (2000), who recorded increased yield in winter wheat in response to increased potassium fertilization.…”

Sharp eyespot caused by Rhizoctonia cerealis was assessed in four winter wheat crops surveyed at four locations in north-central Poland in [2006][2007][2008][2009]. At the four locations symptoms developed on 41.9-67.7 % of shoots of all plants (average of 4 years) and on 49-73.5 % of shoots of diseased plants (average of 4 years). Slight (category 1) disease was most frequent, occurring on 24.4-41.3 % of shoots (range 14.8-51.3 %); moderate (category 2) disease was less frequent, occurring on 16.9-25.5 % of shoots (range 8.9-32.4 %); severe (category 3) disease was least frequent, occurring on 3.2-7.1 % (range 0-22.0 %) of shoots. Sharp eyespot affected wheat growth and yield, and grain quality. Disease, especially in the severe category, was associated with significant decreases in plant and ear dry weights, number of grains per ear, grain dry weight per ear and thousand-grain weight, and with increases in grain protein and wet gluten contents, Hagberg falling number and sedimentation value. There was an association between occurrence of sharp eyespot in stems and colonization of grain by fungi. Alternaria alternata and E. nigrum were the most common species.

“…A more diverse weed community can, in turn, harbour and support a more abundant predator community. Disease control benefited from increased phosphorus availability in the soil (lower water quality regulation, [44]) and this relationship might be stronger when the likelihood of disease incidence increases (higher crop density under fertilized conditions). Moreover, increased plant quality (higher soil phosphorous availability) might indirectly improve parasitoid fitness through improved aphid performance [45].…”

Soil management shapes ecosystem service provision and trade-offs in agricultural landscapes

Agroecosystems are principally managed to maximize food provisioning even if they receive a large array of supporting and regulating ecosystem services (ESs). Hence, comprehensive studies investigating the effects of local management and landscape composition on the provision of and trade-offs between multiple ESs are urgently needed. We explored the effects of conservation tillage, nitrogen fertilization and landscape composition on six ESs (crop production, disease control, soil fertility, water quality regulation, weed and pest control) in winter cereals. Conservation tillage enhanced soil fertility and pest control, decreased water quality regulation and weed control, without affecting crop production and disease control. Fertilization only influenced crop production by increasing grain yield. Landscape intensification reduced the provision of disease and pest control. We also found tillage and landscape composition to interactively affect water quality regulation and weed control. Under N fertilization, conventional tillage resulted in more trade-offs between ESs than conservation tillage. Our results demonstrate that soil management and landscape composition affect the provision of several ESs and that soil management potentially shapes the trade-offs between them.

“…Mondal et al (2001) also found a negative correlation between potassium content in soybean and sesame with disease incidence and a positive correlation between their respective yield. According to Sweeney et al (2000) the positive impact on yield could also be attributed to the effect of chloride supplied with KCl Fertilizer. During present investigation also excess dose, of potassium reduced the disease severity and increase the phenol contents which is supported by the findings of all workers cited earlier.…”

: Application of potassium either as recommended, deficient or excess dose, enhanced the level of phenolic contents, increased incubation period and thereby decreased the sheath blight severity. Application of nitrogen and phosphorous, either as recommended, deficient or excess dose resulted in reduction of phenolic content, shorter incubation period and thereby increasing the sheath blight severity. Recommended sulphur application, enhanced the phenolic contents, increased incubation period and thereby decreased the sheath blight severity. Recommended zinc application resulted in enhancement of phenolic contents, longer incubation period and thereby decreasing the sheath blight severity. Excess application of zinc, reduced the phenolic contents and incubation period but the severity of sheath blight was also lowered down. Recommended iron application (1.5 kg./ha) enhanced the phenolic contents and incubation period with a decreased level of sheath blight severity. Deficient and excess doses of iron also showed the similar trend of effect on phenolics, incubation period and sheath blight severity.
