Question

why frequency of irrigation increases

Answer 1

The effects of two irrigation intervals (1- and 3 days) and three application rates (3-, 6-, and 9 mm day−1) on growth and yield of cabbage (Brassica oleracea var. capitata L.) were studied under the relatively warm (23 °C) and humid (63 per cent R.H.) winter conditions of Oman in the Gulf region. The head weight, head diameter and leaf weight increased significantly with increasing application rate from 3 to 6 mm per day, corresponding to maximum soil moisture tensions of more than 100 kPa and less than 80 kPa respectively.
