DRIS Evaluation of the Nutritional Status of Crisphead Lettuce
Diagnosis and Recommendation Integrated System (DRIS) norms were derived for crisphead lettuce (Lactuca sativa L.) from field fertility experiments conducted over the past 20 years on mineral and organic soils in Florida. Preliminary testing indicates that DRIS diagnoses generally agree with diagnoses using the sufficiency range approach, with the advantage of predicting the degree of nutrient ...
متن کاملHow to Plant Apple Trees to Reduce Replant Disease in Apple Orchard: A Study on the Phenolic Acid of the Replanted Apple Orchard
Apple replant disease (ARD) is an important problem in the production of apple. The phenolic acid is one of the causes of ARD. How phenolic acid affects the ARD was not well known. In this study, we analyzed the type, concentration and annual dynamic variation of phenolic acid in soil from three replanted apple orchards using an accelerated solvent extraction system with high performance liquid...
متن کاملRice Response to the Time and Rate of Potassium Fertilization
Rice (Oryza sativa L.) requires adequate potassium (K) nutrition for optimal growth, grain yield, and disease resistance. Studies were conducted in 2001 and 2002 at the Pine Tree Branch Experiment Station (PTBS) to characterize K uptake by rice and investigate the effect of both K-fertilizer application rate and time on rice growth, K uptake, and grain yield. Potassium fertilizer was applied at...
متن کاملEvaluation of different strain mice during in vitro fertilization and embryo development in response to superovulation
Background: Mice are the most commonly used animal in reproductive research and following the urgent need for these type of studies and also due to the increased interest in the ethical principle of animal rights, four various inbred and outbred strains of the laboratory mouse were evaluated to select the more efficient one for reproductive research. Materials and methods: 60 female and 16 mal...
