Effect of integrated nutrient management on growth and yield of proso millet (Panicum miliaceum L.)

Abstract

A field experiment was conducted to study the integrated nutrient management in proso millet (Panicum miliaceum L.) on lateritic soil having low to moderate soil fertility status during kharif, 2017. Results in the data revealed that, among the various fertilizer levels, 125 per cent RDF recorded significantly higher values of all the growth parameters and yield attributers viz. plant height hill-1, number of functional leaves hill-1, number of functional tillers hill-1 and dry matter accumulation hill-1 over all other lower fertilizer levels under study. Similarly, significantly higher values of yield attributing characters viz., number of panicles hill-1, length of panicle (cm), weight of panicle (g), number of rachis panicle-1 and test weight (g) were recorded at 125 per cent RDF, which resulted into significantly higher grain and straw yield of proso millet over remaining fertilizer levels under study. Among the organic nutrient sources, application of biofertilizer plus green manure treatment recorded significantly higher growth attributes (mean plant height hill-1, number of functional leaves hill-1, number of functional tillers hill-1 and dry matter accumulation hill‑1) and yield attributes of proso millet over remaining organic sources under study. Grain and straw yield of proso millet crop was also significantly superior in biofertilizer plus green manure treatment.
