Abstract

A field experiment was conducted to assess the effect of land configuration, irrigation and nitrogen application on the performance of Japanese mint under saline soil conditions at, Faizabad during summer (Zaid) season of 2016-17. Raised bed planting recorded higher herbage (17957 kg/ha) and dry biomass yield (4843 kg/ha), maximum P content (0.36%), and N (78.9 kg/ha), P (17.4 kg/ha) and K (77.4 kg/ha) uptake. However, increase in N (1.65%) and K (1.62%) content and available N (132.8 kg/ha), P (16.3 kg/ha) and K (224.2 kg/ha) in soil were recorded under flat planting. Irrigation at 1.2 IW/CPE ratio significantly enhanced herbage (17117 kg/ha) and dry biomass yield (4828 kg/ha), maximum P content (0.37%) and the uptake of N (78.7 kg/ha), P (17.9 kg/ha) and K (77.1 kg/ha) by crop. Whereas irrigation at 0.8 IW/CPE ratio recorded maximum N (1.65%) and K (1.62%) content and available N (133.9 kg/ha), P (16.6 kg/ha) and K (243.8 kg/ha) in soil. Application of 125% RDN recorded maximum herbage (17124 kg/ha) and dry biomass yield (4804 kg/ha) with highest N (77.8 kg/ha), P (16.3 kg/ha) and K uptake (76.3 kg/ha) and their availability in soil followed by RDN, but the content of N (1.63%), P (0.35%) and K (1.60%) in plant was the highest with 75% RDN. Raised bed planting of Japanese mint irrigating at 1.2 IW/CEP ratio and the application of 160 kg N/ha (RDN) is better for yield, nutrient uptake and available nutrients in saline soil.
