Canola Response to Nitrogen, Sulfur, Phosphorus, and Potassium Fertilization in Arkansas
Canola (Brassica rapa) is an oilseed crop that is related to broccoli (Brassica oleracea var Italica) and turnip (Brassica campestris var Rapifera). The name ‘canola’ actually stands for ‘Canadian oil, low acid’. Canola’s low erucic acid content differentiates it from rapeseed (Brassica napus) and is sometimes referred to as LEAR or ‘low erucic acid rapeseed.’ Canola seed contains about 40% oil...
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 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 کاملresponse of wheat to seed dressing with humus and foliar potassium fertilization
growing demand for wheat grain with optimal technological parameters results in looking for the possibilities of accurately meeting the plant needs. environmental conditions in the surroundings of germinating grains can be improved by application of humic preparations. qualitative features of grain can be also changed by foliar application of potassium, which is the activator of enzymes catalys...
متن کاملNitrogen, Sulfur, Potassium and Phosphorus Fertilization in Alfalfa When Are They Necessary?
Determining when applications of nitrogen (N), sulfur (S), potassium (K) and phosphorus (P) fertilizer are needed is important to maintain alfalfa yield and quality. The Western U.S. is diverse in terms of climate, soil types, irrigation water need and availability, historical nutrient use and alfalfa production systems. Therefore, few generalizations hold regarding the timing and location of N...
