Under greenhouse condition a pot culture investigation was carried out using Inceptisol soil (Typic Haplustept) contaminating with (134)Cs @ 1microCikg(-1) soil to study the transfer factor to Mustard, Gram, Spinach and Wheat crops as influenced by potassium application (0, 27.3, 54.6 and 81.9mgKkg(-1) soil). Potassium application in general improved the biomass, grain yield and also the potassium concentration in all the crops. Irrespective of the crops, (134)Cs transfer factor to straw and grain was highest in control treatment (no K addition) and found to decrease significantly with increase in K application levels. The (134)Cs uptake was highest in Spinach followed by Mustard, Gram and Wheat crops. The weighted transfer factor values (straw plus grain) to Spinach, Mustard, and Gram were observed to be 5.54, 4.38 and 2.20 times higher as compared to Wheat crop.
在温室条件下，使用被1微居里/千克土壤的¹³⁴Cs污染的始成土（典型湿软土）进行盆栽试验，以研究钾施用（0、27.3、54.6和81.9毫克钾/千克土壤）对芥菜、鹰嘴豆、菠菜和小麦作物转移因子的影响。一般来说，施用钾肥提高了所有作物的生物量、籽粒产量以及钾浓度。无论作物种类如何，¹³⁴Cs向秸秆和籽粒的转移因子在对照处理（不施钾）中最高，且随着钾施用量的增加而显著降低。¹³⁴Cs的吸收量在菠菜中最高，其次是芥菜、鹰嘴豆和小麦作物。与小麦作物相比，菠菜、芥菜和鹰嘴豆的加权转移因子值（秸秆加籽粒）分别高出5.54、4.38和2.20倍。
