Effect of organic and inorganic fertilizers on growth characters of Moringa (Moringa oleifera Lam.) cv. PKM 1.

摘要

An experiment was conducted with M. oleifera, having 21 treatments, involving applications of organic (10 kg farmyard manure (FYM)+250 kg neem [Azadirachta indica] cake (NC)+20 g Azospirillum; FYM+NC+20 g vesicular arbuscular mycorrhizas (VAM); FYM+NC+2% Panchakavya (a plant growth stimulant); 500 g poultry manure (PM)+NC+Azospirillum; PM+NC+VAM; and PM+NC+Panchakavya) and inorganic (recommended dose of NPK (100:100:50 g/pit; 2 splits) and higher dose of NPK (150:150:75 g/pit; 2 splits)) fertilizers. Controls with no organic and inorganic fertilizer applications were included. The organic manures and inorganic fertilizers significantly affected the canopy spread. There was a progressive increase in the spread of the tree from vegetative growth to maturity. The canopy spread was significantly increased (1.82) by the application of PM+NC+Panchakavya at harvesting stage in the main crop. A similar trend was observed for ratoon crop, having 1.88 m canopy spread at harvesting stage. The single treatment of increased level of NPK fertilizer also favourably affected the canopy spread at harvesting stage, i.e. 1.80 m in the main crop and 1.89 in the ratoon crop. The treatment combination of PM+NC+Panchakavya+increased level of NPK was found to be the best, recording the highest canopy spread of 1.93 m in the main crop and 2.04 m in the ratoon crop during harvest stage..
