Evaluation of various sources of organic manures on nitrogen use efficiency in rice-rice cropping system
نویسندگان
چکیده
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 chemical fertilizer and the other was absolute control which were replicated three times. The recommended dose of NPK fertilizer was 90: 40: 40 kg ha -1 for Kharif and Rabi rice. The recommended dose of 90 kg N ha -1

Effect of nitrogen supplying sources on nitrogen use efficiency in rice (Oryza sativa L. cv. Shiroudi)
The use of nitrogen fertilizer has a key role in enhancing agricultural productivity worldwide. In order to achieve an effective approach to enhance nitrogen use efficiency in rice, a field experiment was conducted in a randomized complete block design with three replications and 13 treatments on Shiroudi, a high yielding rice cultivar in Rice Research Institute of Iran (Amol) in 2015 and 2016....
متن کاملEffect of Nitrogen Sources for Spikelet Sterility and Yield of Boro Rice Varieties
Rice yield can be increased in many ways such as developing new high yielding varieties or adopting proper agronomic management to the existing varieties. Proper fertilization is an important management practice to increase rice yield. Proper fertilization can markedly increase the yield and improve the quality of rice [1]. Nitrogenous fertilizer has immense effect on rice yield throughout the ...
متن کاملOrganic Manures and Crop Residues as Fertilizer Substitutes: Impact on Nitrous Oxide Emission, Plant Growth and Grain Yield in Pre-Monsoon Rice Cropping System
It has been previously argued that application of organic residues added in soils has a great impact on soil quality, grain productivity as well as greenhouse gas emissions. Substitution of chemical fertilizers has become a common practice in agricultural systems which consequently affect the greenhouse gas emissions from agricultural fields. To observe the effects of organic manures and crop r...

A 3- years (2015, 2016 and 2017) field study was carried out at National Wheat Research Program, Bhirahawa, Rupandehi, Nepal to evaluate the influence of crop residues and nitrogen levels on rice. The experiment was conducted in split plot design with three replications. Main plots were two crop residue levels (with crop residues of 30 cm wheat stubble and without crop residues) and sub plots c...
