    Efficiency of K and irrigation on nutrient availability and uptake of nutrients in ash gourd
    (Kerala Agricultural University, 1993) Muralidhara Menon, G; Marykutty, K C
    A field experiment was designed to assess the effect of K on available nutrient status of the soil and uptake of nutrients by plants at different irrigation levels. The available nutrient contents of N, K and exchangeable Ca were found to be increased by the application of K while available P and exchangeable Mg content remained unaffected. Available P was more when IW/CPE ratio was 0.50. The uptake of N was significantly influenced by the application of K only at the full vegetative phase. Pand K uptakes were significant both at the full vegetative phase and harvesting stage. The uptake of Ca and Mg decreased as the level of K increased except at the full vegetative phase.
