Effect of Different Drip Irrigation Levels and Cabbage Varieties on Potassium Content and Uptake of Head

An experiment was conducted for two Rabi seasons in the years of 2021 and 2022 on four irrigation levels (60 per cent, 80 per cent, 100 per cent and 120 per cent PE) and four varieties of cabbage (Golden Acre, Pusa Mukta, Pusa Cabbage -1 and Pusa Cabbage Hybrid -81) at College of Agriculture, SKRAU, Bikaner. The experiment was laid out in split plot design with three replications. Results showed that the maximum potassium content in head was obtained under 120 per cent PE of irrigation level (2.03, 2.02 and 2.02 per cent) which was significantly higher over 60 per cent PE irrigation level (1.74, 1.72 and 1.73 per cent) and it was statistically at par with 80 per cent PE and 100 per cent PE irrigation level during the year 2021, 2022 and on pooled mean basis, respectively. The significantly higher uptake of potassium by head (92.21, 93.89 and 93.05 kg ha-1) was recorded under 100 per cent PE level over 60 per cent PE level (62.70, 63.63 and 63.17 kg ha-1) which was statistically at par with 120 per cent PE and 80 per cent PE irrigation levels during 2021, 2022 and on pooled basis, respectively. Among the varieties, significantly higher uptake of potassium by head recorded under Pusa Mukta variety (86.05, 87.40 and 86.72 Kg ha-1) over the Pusa Cabbage Hybrid -81 (71.74, 72.03 and 71.89 Kg ha-1) and it was at par with Golden Acre and Pusa Cabbage -1 were statistically at par with Pusa Mukta variety of cabbage. Potassium content in cabbage head was not significantly affected with different cabbage varieties during both the experimental years.
