Impact of different organic and inorganic sources of nutrients on vegetative growth of marigold (<em>Tagetes erecta</em> L.) under agro-climatic conditions of Ajmer zone

Abstract

The present investigation was conducted at Bhagwant University Ajmer, Rajasthan during the rabi season of years 2019-20 and 2020-21 to find out the combined application of different organic and inorganic sources of nutrients on growth behaviour of Marigold (Tagetes erecta L.) under Agro-climatic conditions of Ajmer Zone. Total ten treatments were used in Randomized Block Design (RBD) and replicated three times. The treatments namely T1- Control, T2- 100% RDF (N:P: K @ 120:80:60 kg/ha), T3-100% RDF + 25% VC, T4- 100% RDF + 25% FYM, T5- 75% RDF + FYM + Biofertilizers, T6- 75% RDF + VC + Biofertilizers, T7- 75% RDF + FYM + VC + Biofertilizers, T8- 50% RDF + FYM + VC + Biofertilizers, T9- 50% RDF + FYM + Biofertilizers and T10- 50% RDF + VC + Biofertilizers. Total 30 treatment combinations were formulated in present experiment. During the experimentation, observations were recorded on various growth characters like plant height, number of primary branches, number of secondary branches, plant spread and stem diameter at various successive stages of growth. Though, the maximum growth and flowering was found in T7- 75% RDF + FYM + VC + Biofertilizers as compared to T8- 50% RDF + FYM + VC + Biofertilizers.
