Abstract Biochar application into soil has potential as a means for reducing greenhouse gas emissions and climate mitigation strategy. In this study, we evaluated the impact of two doses biochar (10 20 t.ha −1 ) applied in 2014, combined with three fertilization levels (N0, N1, N2) on carbon dioxide (CO 2 field conditions during growing season (April – October) 2018. The site is located Nitra r...

A recycling of Phosphorus (P) from the human food chain is mandatory to secure future P supply for production. However, many available recycled fertilizers sewage sludge do not have an adequate bioavailability and, thus, are suitable their application in soils with pH >5.5–6.0, unless being combined efficient mobilization measures. The aim study was test ability red clover (Trifolium pratense L...

Biofertilizer is a relatively safer, environmentally friendly and cost-effective approach as an alternative to reduce chemical fertilizer usage. The selection of bacterial strains with multiple beneficial characteristics are important to maximize the effectiveness on the host plant. Due to aforementioned interest, several Plant Growth-Promoting Rhizobacterial (PGPR) and rhizobial strains were i...

A field study was conducted to determine the effect of organic and mineral-based fertilizers on phytochemical contents in the tubers of two cassava varieties. Treatments were arranged in a split plot design with three replicates. The main plot was fertilizer source (vermicompost, empty fruit bunch compost and inorganic fertilizer) and sub-plot was cassava variety (Medan and Sri Pontian). The am...

A n n u a l W h e a t N e w s l e t t e r V o l. 5 4. The 4-year average for the different fertilizer backgrounds indicated that the least total grain damage by cereal bug larvae was in the block with organic-mineral fertilizer, 5.6 %. Damage in the blocks without fertilizer and with only organic fertilizer was 5.9 and 6.0 %, respectively. Total damage was 4.2–4.9 % in seed with a score of 2, w...

The efficient management of nitrogen (N) fertilizer and irrigation is of utmost importance because they are two of the greatest expenses for corn production. This project was conducted to determine if yield and efficiency of fertilizer N in corn could be improved by applying N at later developmental stages through a subsurface drip irrigation (SDI) system. Experiments in 2014 and 2015 compared ...

This paper assesses the origins of and changes to fertilizer policy in Nepal over a period of time. It assesses farmers’ awareness of the recent changes to the subsidy policy and examines their perceptions of the extension services. This paper looks at the environmental implications of the concentrated application of chemical fertilizer, particularly as far as food security is concerned. Questi...

Fertilizer management is one of the easiest and most practical ways combating salt stress. This study was done to evaluate alleviative effects nitrogen phosphorus on growth tolerance salt-affected sorghum. A controlled organized in a randomized block design with three replications conducted, testing rates (N0: 0 kg ha−1, N1: 180 N2: 360 N ha−1) (P0: P2O5 P1: 60 P2: 120 ha−1). Nitrogen applicati...

High N loss and low N use efficiency (NUE), caused by high N fertilizer inputs and inappropriate fertilization patterns, have become important issues in the rice (Oryza sativa L.) growing regions of southern China. Changing current farmer fertilizer practice (FFP, 225 kg ha-1 N as three applications, 40% as basal fertilizer, 30% as tillering fertilizer and 30% as jointing fertilizer) to one-tim...

15N-labeled fertilizer was applied to Sorghum at different rates (0, 100 kg N.ha -1 ) to 1m2 microplots and with two kind of water (well water “WW” and treated wastewater “TWW”) to Sorghum grown in field during 1997 and 1999. Increases in DM production, N uptake and 15 NRF were observed with TWW. About 17% and 36% of the 15Nfertilizer were recovered in the crop with TWW in 1997 and 1999, respec...
