A 2-year field study was carried out to find out the effect of three macro nutrients NPK on the severity of Alternaria leaf blight and yield of mustard. Nitrogen @ 80, 100, 120, 140, and 160, phosphorus @ 15, 30, and 45, and potassium @ 30, 60, and 90 kg/ha were applied. Among the nutrients, 120-3060 kg NPK/ha was considered as recommended dose on the basis of soil test. Fertilizer dose 120-30-...

This study assesses the effect of long-term (59 years) application of organic and inorganic fertilizers on soil organic matter and enzyme activity. Total organic C, total organic N, hot water soluble C, microbial biomass C and dehydrogenase activity were evaluated in soil from the long-term field experiment in Prague-Ruzyně (Orthic Luvisol, clay loam). Total organic C and N increased significan...

Green manure, used for eco-friendly agriculture, supplies organic matter (OM) and nutrients to soil improves fertility. manuring also has the potential affect physical stability carbon storage. The objective of this study was investigate effect green manure on water-stable aggregates stock in paddy. Soil samples were collected from 3 treatments Chungcheongnam-do Agricultural Research Extension ...

Investigations were carried out to study the effect of organic farming with various sources of organic manures and their combinations on nitrogen use efficiency parameters of ADT 36 rice (Oryza sativa L.). The experiments were laid out in randomized block design (RBD) with fourteen treatments, comprising twelve treatment combinations of organic manures, one treatment with recommended dose of ch...

greater than CO2 (Callander et al., 1995). Therefore, the objective of the present work was to quantify the annual emission of N2O from winter rye, M. ‘Giganteus’ and winter oilseed rape. Furthermore the N2O emission will be related to the estimated net CO2-displacement. The annual emissions of N2O were measured using a closed-chamber technique and were based on results obtained by Jørgensen et...

The use of biochar as a soil amendment has substantial potential to enhance quality and carbon sequestration. However, the responses addition based on microbial residues are not well understood, particularly at aggregate level. Herein, two-year field experiment investigated characteristics distribution in calcareous fluvo-aquic aggregates (SA) Henan Province, China. Four treatments were establi...

The present study was carried out for three successive seasons 2008/2009, 2009/2010 and 2010/2011 on fifteen years old of olive trees cv. Picual to reduce the degree of alternate bearing through fertilization by NPK over than the rates recommended by the Ministry of Agriculture and Lands Reclamation. The obtained results showed that, fertilizing olive trees with 50% over NPK recommended doses i...
