Abstract:
To ascertain the impact of soil salinity on pigeon pea biochemical parameters, a pot experiment was carried out. The experiment includes five salinity levels (Control, 40, 60, 80 and 100 meq l^-1) and four pigeon pea varieties (V₁: GJP-1, V₂: Vaishali, V3: BDN-2, V₄: AGT-2) in Completely Randomized Design (Factorial) replicated three times. According to biochemical characteristics (proline content) variety V₄ (AGT-2) had the maximum proline accumulation (0.980 mole/g f. wt), which rose with increasing salt levels. Variety V₄ (AGT-2) outperformed the other examined varieties in terms of RWC, chlorophyll a, chlorophyll b, and total chlorophyll content in pigeon pea leaves at 45 DAS. These metrics also declined as the saline level rose. So it can be concluded that variety V₄ (AGT-2) is salt-tolerant due to the highest concentration of proline, RWC, chlorophyll a, chlorophyll b and total chlorophyll content were obtained in it.
