Efficacy of Different Levels of NPK against Anthracnose of King Chilli (Capsicum chinense) Caused by Colletotrichum gloeosporioides (Penz.) and Impact on Their Growth Parameters and Yield in Manipur

A significant disease in Capsicum that reduces crop output is anthracnose. In the current study, the effectiveness of various NPK dosages (N1-120 Kg, N2 -150 Kg, N3-90 Kg, P1-60 Kg, P2-75 Kg, P3-45 Kg, K1-60 Kg, K2-75 Kg, K3-45 Kg) against Colletotrichum gloeosporioides which caused Anthracnose diseases in King chilli and their effects on growth parameters and yield were assessed. The experiment described in Randomized Block Design (RBD) was conducted at KVK Thoubal, Manipur, from October 2021 to April 2022. Results showed that amongst the fertilizers, application of increased doses of P and K exhibited significant management of anthracnose of King chilli with 25.00% and 19.66% disease severity and ‘Control’ (60.00%) revealed high disease severity and reduced yield. The increased level of P and K also produced maximum yield with 11.17 Kg/plot and 9.30 Kg/plot in fresh weight respectively. Thus application with increased level of P and K has paramount importance in combating anthracnose in King chilli which significantly increase in the growth parameters and yield.
