Abstract

An investigation entitled “Effect of nitrogen, phosphorus and potassium on growth and yield of Arvi (Colocasia esculenta L.)” was carried out at Horticulture Research Centre of Sardar Vallabhbhai Patel University of Agriculture and Technology, Meerut during 2017-18 in Randomized Block Design (RBD) with three replications. Total ten treatment viz. T1- NPK 60:30:80 kg ha-1,T2 - NPK 60 :60:120 kg ha-1, T3-NPK 60 :90:160 kg ha-1 , T4 - NPK 90:30:80 kg ha-1, T5-NPK 90:60:120 kg ha-1, T6-NPK 90:90:160 kg ha-1, T7-NPK 120:30:80 kg ha-1, T8-NPK 120:60:120 kg ha-1, T9-NPK 120:90:160 kg ha-1 and T10- Control were tried to assess the impact of nitrogen, phosphorous and potassium on growth and yield of colocasia during investigation. Out of these, the treatment with NPK 120:30:80 was found significantly superior in terms of plant height (cm.), plant spread (cm), number of leaves plant-1, number of tillers plant-1, girth of pseudo stem from ground level (cm) , length of leaf (cm), width of leaf (cm), petiole length (cm) and petiole breadth (cm). Similarly, yield and yield attributing parameters i.e., number of corms plant-1 , corm length (cm), corm girth (cm), weight of corm (g), corm yield plant-1 (g), and corm yield (q ha-1) were found significantly superior with the application of NPK 120:30:80 as compared to control and other treatments. Finally, a dose of NPK @ 120:30:80 kg ha-1 gave the highest yield of corm i.e., 289.83 q ha-1, whereas lowest yield of corm i.e., 92.25 q ha-1 was observed under control during the cropping period.
