Influence of Different Potassium (K) Application On Seed Glucosinolate Content Of Brassica Under Stress Condition In The Field

Abstract

Field experiments were laid out in randomized complete block design (RCBD) with split plot arrangements at Malakandher Research Farm Khyber Pakhtunkhwa Agricultural University Peshawar Pakistan to study the effect of different levels of irrigation and potassium on seed protein content of Brassica. Four varieties Wester, Rainbow, Oscar and Legend were selected on the basis of their good response to potassium application in water stress conditions. maximum GSL content (49.2 ?mol g-1) was observed in treatments of 100% irrigation while minimum GSL content (16.4 ?mol g-1) was produced by plants where 60% irrigation was applied. potassium showed maximum GSL content (34.7 ?mol g-1) with 60 kg K ha-1 and minimum GSL content (31.0 ?mol g-1) was observed in treatments with 120 K kg ha-1. The data shown in appendix A29 suggested that maximum GSL content (40.7 ?mol g-1) was produced by variety Wester (V1) when applied with 60 kg K ha-1 and minimum GSL content (25.7 ?mol g-1) was given by variety Legend (V4) when treated with 120 kg K ha-. case of interaction between I x K, maximum GSL content (50.7 ?mol g-1) was noted in plants treated with 60 kg K ha-1 and 100% irrigation level while minimum GSL content (14.1 ?mol g-1 ) with 120 kg K ha-1 and 60% irrigation level. Further, the data given in appendix A29 indicated that maximum GSL content (56.5 ?mol g-1) was produced by variety Wester (V1) when treated with 100% irrigation level and 60 kg K ha-1 while minimum GSL content (8.9 ?mol g-1) was also given by variety Wester (V1) at 120 kg K ha-1 and 60% irrigation level.
