| dc.description.abstract | A field experiment was conducted at the College of Agriculture, Vellayani, during the period June-December 1995, to study the effects of different doses of nitrogen, phosphorus and potassium on the growth, yield and quality of mango-ginger. The treatments consisted of factorial combinations of 3 levels each of nitrogen (15, 30 and 45 kg N ha-1), phosphorus (15, 30 and 45 kg P2O5 ha-1) and potassium (30, 60 and 90 kg K2O ha-l) with absolute control. The experiment was laid out as 33+1 Factorial Randomised Block Design with three replications. Nitrogen (30 kg ha-1) recorded maximum values for most of the characters namely plant height, leaf area index, dry matter production, crop growth rate, bulking rate, top yield, fresh rhizome yield, recovery of dry rhizome, volatile oil. Application of highest dose namely, 45 kg N ha-l resulted in highest number of tillers, number of leaves, utilization index, harvest index, non-volatile ether extract, fibre content and chlorophyll content. Phosphorus (30 kg ha-1) registered higher values for plant height, number of leaves, leaf area index, bulking rate, rhizome spread, fresh rhizome yield and recovery of dry rhizome. Application of 45 kg P205 ha-1 produced maximum sprouting, number of tillers, number of leaves, dry matter production, net assimi- lation rate, top yield, volatile oil, fibre content and chlorophyll fractions. Application of 60 kg K20 ha-1 registered maximum leaf area index, bulking rate, fresh rhizome yield, recovery of dry rhizome, utilization index, harvest index and fibre content. Potassium at 90 kg K20 ha-1 recorded highest plant height, number of tillers, number of leaves and top yield. Lower dose of 30 kg K20 ha-1 produced higher volatile oil, non-volatile ether extract and chlorophyll contents. Significant increase in nutrient uptake was observed with their application at higher levels. Soil nutrient status after the experiment was maximum at higher rates of application of the respective nutrients. Among treatment combinations 30:30:60 kg NPK recorded maximum fresh rhizome yield. This combination also recorded the highest net returns and benefit cost ratio. Thus 30:30:60 kg NPK ha-1 can be recommended as the fertilizer dose for mango-ginger. The physical and economic optimum dose was worked out to be 33:28:62 kg N, P2O5 and K2O ha-1. | en_US |
