Abstract :

Kodo millet (Paspalum scrobiculatum L.) is a climate resilient nutri-cereal, which has tremendous potential to improve food and nutritional security in rain-fed environments. To study the impact of nutrient levels on the growth, yield, economics and stability of pre-released Kodo millet genotypes, a field experiment was conducted at the Zonal Agricultural Research Station (ZARS), University of Agricultural Sciences, Bengaluru, Gandhi Krishi Vigyana Kendra (GKVK), Karnataka during kharif season. This experiment was designed in a Factorial Randomized Complete Block Design with three replications, four fertility levels (control, 75% RDF, 100% RDF and 125% RDF) and three genotypes (KMV 588, TNAU 86 and JK 137). The results indicated that the fertility levels and the genotypes of Kodo millet significantly affected growth, yield and economic data. Increased levels of fertility resulted in better growth, yield attributes, yield, straw yield, and profitability. The genotype TNAU 86 always performed well in terms of productivity and economic returns. Stability analysis using Eberhart and Russell model showed that TNAU 86 had high yield potential, extensive adaptability and stable performance in various fertility environments. The study demonstrated that the use of 125% RDF gave improved productivity and profitability, with the introduction of TNAU 86 as the most promising genotype in the sustainable cultivation of Kodo millet under rain fed conditions.
