Abstract
The effect of simulated overhead flash flooding for 10 days at an early vegetative stage of rice grown from transplanted seedlings with and without fertilizer N applied to the nursery soil, was studied under intermediate deepwater conditions at Cuttack, India. Application of 100 kg fertilizer N per ha to nursery soil at sowing or in splits improved seedling vigor measured as dry weight and N concentration of the plant tissue at transplanting. The crop raised with healthy and vigorous N-fertilized seedlings was more tolerant to ravages of flooding and showed a better stand with more profuse tillering and less mortality. The grain yield of the semi-tall cultivar Suresh was not affected by N applied to the nursery soil under partial submergence of 70±2 cm water depth. However, the semi-dwarf cultivar Gayatri planted with N-fertilized seedlings established better in the early stages and produced more panicles and a two- to five-time higher grain yield. The beneficial effect of nursery fertilization was less marked under natural flooding conditions (25–40 cm). Transplanting semi-dwarf rice with healthy and vigorous seedlings obtained by fertilizing nursery seed-bed could therefore, be a very productive low-cost technology for farmers growing rice under conditions of intermediate deepwater and flash floods.
