This study investigated the combined effects of drip irrigation and mulches on yield, water-use efficiency and economic return of tomato. The treatments of the study comprised different combinations of three drip irrigation levels (100, 75 and 50% of crop water requirement, ETc) and two mulches (black polyethylene sheet and paddy straw). The yield and yield-contributing characters in the mulched treatments for all levels of irrigation were significantly higher compared to those in the unmulched treatments. The yield of tomato increased with the increasing amount of irrigation water in unmulched treatment. The trend was reversed when drip irrigation...

Chlorine, one of the most abundant elements in nature, undergoes a complex biogeochemical cycle in the environment, involved in the formation of volatile organochlorines (VOCls), which in turn can contribute to environmental problems, contaminate natural ecosystems, and are of public health concern. Several industrial and natural sources of VOCls have already been identified; however, data - particularly on the natural sources - are still scarce. The aim of this study was to investigate the diversity of emission of VOCls from soil and several undergrowth plants collected in temperate spruce forest ecosystem and the effect of salting on the VOCl emission...

In this paper the data measured by application of the MDS NZ2 field rainfall simulator have been used to demonstrate the effect of vegetation cover on surface runoff generation and soil loss. The results of 15 experiments for two crops (oats and wheat) are presented. Canopy cover and the leaf area index are used to describe the vegetation development. Measured soil loss decreased with growing vegetation significantly from the maximum values 74.7 g/min for oats (38.4 g/min for wheat) to 0.4 g/min (1.5 g/min respectively) from the experimental plot of 16 m2. Thus, this work clearly demonstrates the positive effect of canopy development on...

In Northwestern China, the carbon fixing capacity of black locust (Robinia pseudoacacia) has been questioned because of its slow growth following the return of unproductive farmland to forest. To explore the effects of stand age on the carbon sequestration potential of R. pseudoacacia in a semi-arid, ecologically fragile area, parameters related to carbon fixation were investigated in plots of three stand ages (5, 10, and 25 years). Each plot was divided into four subsystems: R. pseudoacacia, understory vegetation, litter, and soil, and the carbon stored capacity of each subsystem was estimated. The organic carbon density...

Phosphorus (P) availability limits crop growth in most of cultivable soils in north-west India. The beneficial rhizosphere microorganisms such as phosphate-solubilising fungi (PSF) were found to increase P availability in soil and improve crop yields. In view of this, field experiments were conducted during 2009-2011 to evaluate the effect of seed inoculation with PSF (Penicillium bilaii) at different rates of fertilizer P on P content in leaves and grain yield of irrigated wheat in India. The soil was low in Olsen P at the Bathinda site and medium at the Ludhiana site. In no-P treatment, PSF significantly increased grain yield by 12.6% over...

The changes of saprotrophic fungi (SF) and symbiotic arbuscular mycorrhizal fungi (AMF) in response to different fertilizers were investigated in a period of 21 years. Denaturing gradient gel electrophoresis profiles showed fungal community structure significantly changed after long-term fertilization. Long-term organic and mineral fertilization significantly increased the SF diversity, whereas mineral fertilization decreased the AMF diversity. SF quantity significantly increased in response to organic fertilizers, whereas the AMF propagules were down-regulated by nutrient-rich fertilization but induced by N, P or K-deficiency. Redundancy analysis...

This paper deals with the efficiency of nitrogen (N) and sulphur (S) fertilization on yields and value of N:S ratio for hybrid ryegrass cultivated in monoculture and in a mix with white clover. The research was carried out from 2011-2013 near Krakow in southern Poland. Plants were evaluated in the context of diversified fertilization with nitrogen at rates of 50 and 100 kg N/ha as well as two sulphur-based fertilizers: Arista siarka and Pro-siarka, used at rates of 5, 10, 15 kg S/ha. Independent research findings have shown a clear synergism between nitrogen and sulphur, namely fertilization with sulphur in the form of Arysta siarka and Pro-siarka...
