Subject:
Solanum tuberosum; climate; crop yield; denitrification; greenhouse gas emissions; humidity; microbial activity; nitrogen; nitrogen fertilizers; nitrous oxide; pellets; potatoes; shrimp shells; temperature
Abstract:
... In organic plant production, nitrogen (N) availability is often a growth-limiting factor. Under such conditions, off-farm waste-derived nutrient resources may be an alternative to meet the N demand. In this study, we described a production method for a shrimp shell (SS) pellet product and evaluated the N fertiliser effect and N recovery efficiency (NRE) in a controlled climate pot experiment with ...

Abstract:
... The corn-grass intercropping system began to be used in the dry season, as it provides increased straw production for the no-tillage system. However, corn and grass are plants demanding in nitrogen. The corn cultivated in the dry season is called out-of-season corn in Brazil. The objective of this study was to evaluate the productivity and nutrients concentrations of out-of-season corn and Congo-g ...

NPK fertilizers; Trifolium pratense; barley; crop rotation; crop yield; eutrophication; fertilizer application; field experimentation; forage grasses; harvest date; humus; meteorological parameters; nutrients; organic fertilizers; phosphorus; potassium; potatoes; rye; soil; surface water; winter; Estonia
Abstract:
... Soil is an element of crop cultivation that demands consistent fertilisation to compensate for the nutrients that are removed by the harvest. Changes in soil because of prolonged fertilisation can only be estimated by long-term field trials. Experiments in long-term field trial site Kuusiku (since 1965) include crop rotation of potato, late harvest barley, early harvest barley undersown with forag ...

Subject:
Triticum; biomass; genotype; growing season; hydroponics; nitrogen; nutrient use efficiency; phenotype; screening; soil; soil quality; wheat
Abstract:
... Nitrogen uptake being part of nitrogen use efficiency (NUE) is largely decided by root traits. Root traits variability has hardly been explored by breeders mainly because of difficulties in scoring. The hydroponic system requiring lesser space for precise phenotyping of large numbers of genotypes independently of the growing season can be a suitable alternative. However, the effectiveness of hydro ...

Abstract:
... Our objectives were to investigate whether AP affects the soil bacterial community composition and diversity in high-level available phosphorus (AP) soils. The bacterial community was analysed through high-throughput sequencing using the Illumina MiSeq platform. Fifteen soils, including barren land, cropland and greenhouse soils which were sandy loam Fluvisols, were selected from different fields ...

Abstract:
... Regardless of variable environmental conditions and changing pathogen populations, the Estonian potato cultivar (cv.) Ando has shown elevated field resistance to Phytophthora infestans for over 40 years. One of cv. Ando’s parents, the Latvian cultivar Agra, is considered a cultivar of medium to low resistance, the other parent, line 382-48, has a well-known source of resistance, Solanum demissum, ...

Abstract:
... Growing bananas in monoculture leads to less diversity of soil microbial community, the accumulation of soil-borne pathogens and soil degradation in field. In this study, the population of Fusarium oxysporum f.sp. cubense tropical race 4 (Foc TR4) in untreated soil and treated soil with bio-organic fertiliser and anaerobic soil disinfestations (ASD) was first time monitored in a banana field in so ...
