Influence of molybdenum application on soil nutrient status and uptake by cauliflower (Brassica oleracea var. botrytis L.) in an Acid Alfisol soil

Abstract

A field investigation was carried out to evaluate the impact of molybdenum (Mo) application on the yield and nutrient status of cauliflower in an acid Alfisol. The experiment comprised eleven treatments, replicated thrice in a randomized block design (RBD). The highest marketable yield of 558.8 g plant-1 was recorded in treatment with a recommended dose of NPK + FYM, with an increase of 29.1 percent over control (T1). The same treatment enhanced the uptake of macro-and micronutrients. Mo application positively influenced the curd productivity and soil nutrient status, with the conjoint application (soil plus foliar) out performing other treatments. In conclusion, cauliflower crop grown on Mo deficient soil responds positively to its conjoint application (soil plus foliar). However, the sole foliar application of Mo @0.1% recorded the highest apparent nutrient recovery (ANR) and bioaccumulation factor (BAF), with corresponding values of 2.2% and 41.2, respectively.
