| Popis: | Proper scheduling of irrigation and fertilizer is necessary for better crop production and soil health under the climatic condition of a particular region. We conducted a field experiment to develop proper schedule of irrigation and urea fertilizer applications for cabbage under field condition during 2017. Following four irrigation and urea fertilizer scheduling treatments with three repeats were tested in the study: T1: 5 days, T2: 15 days, T3: 25 days and T4: (15 days no fertilizer). The results showed that the soil density (?d) EC (dS m-1), SAR, ESP and Cl- increased, whereas the soil porosity (?), void ratio (e) and pH decreased significantly with the frequent irrigation and fertilizer scheduling. The macro-nutrients in the soil i.e. nitrogen, phosphorous and potash increased under all treatments, except without fertilization. The nitrogen, phosphorous and potash contents of the soil were found maximum at 25 days irrigation and urea fertilization scheduling compared to 5, 15 and control. The yield of cabbage increased from 6-51% and water productivity increased from 15-55% with 25 days irrigation and urea fertilization scheduling compared to 5, 15 and content. The irrigation and urea fertilizer may be applied to cabbage crop with the schedule of 25 days. |
