Response of Seed and Oil Yields and Phosphorus Agronomic Efficiency of Soybean to Simultaneous Placement of Nitrogen with Phosphorus under Drought Stress
In order to study yield, yield components and agronomic efficiency of phosphorus in soybean affected by simultaneous placement of nitrogen with phosphorus, an experiment was carried out under moisture stress conditions, at Agricultural Research Station of Bu Ali Sina University, Hamedan, Iran in 2017 in a factorial split plot based on randomized complete block design with three replications. Th...
متن کاملEvidence of genetic tolerance to low availability of phosphorus in the soil among genotypes of Coffea canephora.
The expansion of agriculture to new areas in order to increase the competitiveness of coffee producing countries has resulted in cultivation expanding into regions with lower natural fertility. This scenario has created the need to differentiate genotypes of Conilon coffee based on their tolerance to low levels of nutrients in the soil, especially phosphorus, which imposes high limitations on c...
متن کاملAdaptability and stability of conilon coffee in areas of high altitude.
In view of the predicted models of global climate change and differences in prices and production costs, there is increased interest in Coffea canephora cultivation in areas of high altitude. However, this species is sensitive to low temperatures, where genotypes vary regarding adaptation/tolerance mechanisms, demonstrating genotype x environment interaction. The aim of this study was to evalua...
متن کاملResponse of Young Citrus Trees on Selected Rootstocks to Nitrogen, Phosphorus, and Potassium Fertilization
The majority of the citriculture in Brazil is located in the state of São Paulo, with a total production area of 700,000 ha. Trees are grafted mostly on ‘Rangpur’ lime (RL; Citrus limonia Osbeck) rootstock. Despite its good horticultural performance, use of other rootstocks has increased with the search for disease-tolerant varieties to improve grove productivity and longevity. Furthermore, the...
متن کاملChanges in Olsen Phosphorus Concentration and Its Response to Phosphorus Balance in Black Soils under Different Long-Term Fertilization Patterns
The Olsen phosphorus (P) concentration of a soil is a key index that can be used to evaluate the P supply capacity of the soil and to estimate the optimal P fertilization rate. A study of the relationship between the soil Olsen P concentration and the P balance (P input minus P output) and their variations among different fertilization patterns will help to provide useful information for proper...
