March 2021 | Volume 37 | Issue 1 | Page 209 Sarhad Journal of Agriculture Research Article Introduction C hickpea (Cicer arietinum L.) is susceptible to diferent factors (biotic and a-biotic) that infuence the production of the crop. Chickpea blight disease caused by the pathogen, Ascochyta rabiei (Pass) Labr, may result in up to 70% crop losses (Nene, 1984; Malik and Bashir, 1984) when environmental conditions are favorable for the disease. Although plant disease can be controlled by a range of cultural practices (Sattar, 1933; Luthra and Bedi, 1935) and chemo-therapentants (Tripathi et al., 1987; Singh and Singh, 1990), cultivation of resistant cultivars is mainly valuable and cost-efective practices (Nene and Reddy, 1987). Plant resistance to an infectious organism is governed by a lot of biochemical metabolites through which enzyme-catalyzed biochemical reactions (Tenhaken and Barz, 1991) depend on the accessibility of defnite anion; cation, and enzymes (Chen and Strange, 1991). Nutrients Abstract | Adequate nutrition plays a very important role in mitigating disease damage. Nevertheless, no specifc rule exists that how a specifc nutrient can alter the severity of the disease. Normally, plants are stressed by diferent environmental confnes may be weakened and susceptible to disease and these include nutrient scarce plants. Tissue contents of potassium, nitrogen, and phosphorus of above parts of the ground of plant in three cultivars of chickpea (‘C-44’, Bittle-98’ and ‘Pb-91’) after treatment with Bion ® (acibenzolar-S- methyl), salicylic acid (SA), potassium hydroxide (KOH) or plant extracts of neem (A. indica A. Juss.), datura (D. metel L.) and garlic (A. sativum L.) were investigated 7 and 14 days after inoculation with Ascochyta rabiei. Elevated nitrogen (2.95%), potassium (1.05%) and potassium (533.00 ppm) contents in the tissues decreased disease severity (79.3%) in cv. C-44. Tese increases were signifcant (P ≤ 0.05) after 14 days of inoculation with plant pathogen in plants pretreated with chemicals. Tere was no signifcant change in plants treated with the plant extracts except with extracts of A. indica. Chemically increased N, P, and K were highest in cultivar C-44 followed by Pb-91 and Bittle-98. A similar trend was observed with plant extract treated plants, with the greatest efect observed with A. indica extracts. Te results indicate that chemicals reported to induce resistance to pathogens may increase mineral contents which prevent the spread of the pathogen.
