Effect of Foliar Application of Water Soluble Fertilizer (WSF) on Growth, Yield and Nutrient Uptake in Little Millet

M. JYOSTNA KIRANMAI, R. Narasimhulu, B. H. Chaithanya, E. Venkataramana & S. BALAJI NAYAK · Asian Journal of Soil Science and Plant Nutrition · 2026

A field experiment was conducted during rabi 2021–22 and 2022–23 to evaluate the effect of different levels of the recommended dose of fertilisers (RDF) in combination with foliar application of water-soluble fertilisers on the growth, yield, and economics of rice. The experiment...

Genetic Variability Studies for Morpho-Physiological and Yield-attributing Traits in Foxtail Millet (Setaria italica L. Beauv.)

B. Harsha Vardhan, R. Narasimhulu, M. Shanthi Priya & A. Chandra Sekhar · International Journal of Environment and Climate Change · 2024

Foxtail millet is an underutilized crop which has high nutritional values and wide genetic resources, possessing the ability to tolerate several abiotic stresses efficiently. Those resources must be used in order to improve desired traits, primarily yield attributes. This investi...

Genetic Variability in Groundnut: Decoding Effects on Yield, Disease Resistance and Nut Quality

A. Rupa, B. Rupesh Kumar Reddy, R. Narasimhulu & M. Pradeep · Journal of Advances in Biology & Biotechnology · 2025

Groundnut (Arachis hypogaea L.) is a globally important oilseed and food legume whose productivity and end-use value are shaped by complex interactions among genetic variability, target trait architecture, and highly variable production environments. Despite the crop’s polyploid...

Character Association and Path Coefficient Analysis of Yield and Morpho-physiological Traits in Foxtail Millet (Setaria italica (L.) P. Beauv.)

Uppala Sai Ram, B. Santhosh Kumar Naik, R. Narasimhulu, D. Venkatesh Babu & M. Reddi Sekhar · Journal of Advances in Biology & Biotechnology · 2025

The character association and path coefficient analysis studies were carried out for 18 yield and morpho-physiological traits in 40 foxtail millet (Setaria italica (L.) P. Beauv.) germplasm accessions. The phenotypic and genotypic correlation analyses revealed strong positive ass...
