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 کاملEvaluation of various sources of organic manures on nitrogen use efficiency in rice-rice cropping system
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...
متن کاملBreeding for high water-use efficiency.
There is a pressing need to improve the water-use efficiency of rain-fed and irrigated crop production. Breeding crop varieties with higher water-use efficiency is seen as providing part of the solution. Three key processes can be exploited in breeding for high water-use efficiency: (i) moving more of the available water through the crop rather than it being wasted as evaporation from the soil ...
متن کاملNitrogen Dynamics and Fertilizer Use Efficiency in Rice Using the Nitrogen-15 Isotope Techniques
Nitrogen-15 ( N)-labeled biogas slurry (digested anaerobic organic residues (DAOR)) and chemical 15 fertilizer (CF) were applied to soil with low fertility cropped with rice. The N dilution method was used to 15 estimate the N uptake and recovery; potted soil was labeled with 1.0 atom % excess [ N] ammonium chloride 15 NH Cl. Certain select soil characteristics were also measured in soil amende...
متن کاملa study of nitrogen use efficiency in two soil organic matter levels for neda rice cultivar
field experiments were conducted at the rice research institute (mazandaran province) using randomized complete block designs in two fields of different levels of organic carbon (low and medium) during two cropping years. the treatments were repeated in three replicates and while seven nitrogen levels (urea-n input) 0, 23, 46, 69, 92, 115 and 138 kg n per ha employed. results indicated that opt...
