Abstract
A field experiment was conducted during “kharif” and “rabi” seasons of 2022-23 and 2023-24 at Regional Agricultural Research Station, Nandyal, Acharya N.G. Ranga Agricultural University, Andhra Pradeshusing “split-plot design” with three replications to study the effect of different enriched organic manures and liquid foliar management practices ondry matter production and nutrient uptake by foxtail millet and chickpea. Among the different enriched organic manures, significantly higher dry matter production (3049 and 1576 kg ha-1) and nitrogen (21.6 and 14.3 kg ha-1), phosphorous (8.16 and 8.98 kg ha-1), potassium (23.69 and 26.56 kg ha-1) uptake of foxtail millet and chickpea respectively were obtained with the application of enriched poultry manure with silica (M2) followed by enriched vermicompost with silica (M3). With respect to liquid foliar feeders, higher dry matter production (3034 and 1570 kg ha-1) and nitrogen (21.7 and 14.37 kg ha-1), phosphorous (8.15 and 9.07 kg ha-1), potassium (23.7 and 26.6 kg ha-1) uptake respectively were recorded with foliar application of panchagavya @ 3 % (F3) which is not significantly different with foliar application of compost tea @ 5% (F4) in foxtail millet and chickpea on clayey loam soils of Scarce rainfall Agro-Climatic Zone of Andhra Pradesh. The lowest dry matter production and nutrient uptake were obtained with control treatment in both the crops.
