Abstract
The present investigations were conducted at Student's Instructional Farm A.N.D.U.A. & T. Kumarganj, Ayodhya, during Rabi season, 2020-21 with the title entitled “Screening of chickpea germplasm and evaluation of insecticides against chickpea pod borer (Helicoverpa armigera Hub.)”. Chickpea (Cicer arietinum L.) is one of the most important leguminous crop and is extensively cultivated in dry and rain-fed areas of the world. Bengal gram is a cheap and important source of protein for those people who cannot afford animal protein or who are largely vegetarian. Chickpea is an important Rabi pulse crop of India and has been considered as “king of pulses” . In India, the total area under chickpea is 106 Lha with the production of > 111 Lt. with productivity 1056 kg/ha. MP has contributed a significant 34% of the total gram area and 41% of total gram production in the country.
Out of 30 germplasm screened against H. armigera twenty germplasm ere tolerant viz. NDG 15-9, Vijay, GCP-105, BG-372, NDG 15-5, IPC 2004-52, PDG 84-16, RSG-880, NDG 16-2, NDG 16-1,DCP 92-3, NDG 15-3, NDG 15-8, Vaibhav, NDG 15-7,SAKI 9516, NDG 15-6, PBC-503, L-550 and Pusa 362, ten were moderate tolerant viz. Pant G-186, NDG 98-3, JG-315, Phule G-5, Rajash, JAKI-9218, NDG 15-10, D-19, NDG 16-3, Radhe and remaining 2 germplasm(NDG 15-4, Udai) were susceptible.
Field evaluation of insecticides against gram pod borer (H. armigera) was carried out by using 7 insecticides, Out of them maximum mortality observed in Emamectin benzoate 5%SG (85.83%) followed by Flubendiamide 39.35% SC (74.90%), indoxacarb 14.5% (62.54%), Spinoturum 11.7% (62.54%), Spinosad 45% SC (55.66%), Azadiractin 1% SC (50.18%) and Neem oil (44.33%).
The highest cost: benefit ratio (1:12.31) was obtained from Emamectin benzoate 5%SG @ 220ml/ha.
