Description Not Available
We assessed the improvement potential of pressmud – a sugar industry waste – on
soil properties, physiological adaptation and yield-related traits in a rice–wheat rotation
in sodicity-affected Ghaghar basin of Haryana, India. Large-scale (0.2–0.4 ha)
participatory trials comprising two treatments, with ( +PM) and without (–PM) pressmud,
were conducted on 125 farmers' fields covering non-sodic (NS), slightly sodic
(SS) and moderately sodic (MS) soils. Pressmud application (10 Mg ha−1) led to appreciable
reductions in soil pH (1.6–3.6%) and exchangeable sodium percentage (ESP;
10.4–20.1%) with concomitant improvements in plant physiological and yield-related
traits across different soil alkali classes, albeit to a greater extent in SS and MS soils
than in NS soils. Compared to prevailing farmers' practices (–PM), transformative
improvements in mean leaf relative water content (RWC) (4 and 7%), membrane
injury (MII) (−12 and −14%), photosynthetic rate (Pn) (21 and 25%), stomatal conductance
(gS) (26 and 21%), transpiration rate (E) (38 and 22%), proline (P) (−19 and
−20%) and Na +/K + accumulation in shoot (NaK_S) (−24 and −22%) and root (NaK_R)
(−23 and −27%) were observed in both rice and wheat grown under PM ameliorated
soils. On an average, rice and wheat yields were increased by 15.8 and 14.6% in SS
and 18.9 and 16.7% in MS soils, respectively, with pressmud application. Principal
Component Analysis (PCA) showed significant correlations among highly weighted
variables including physiological and yield-related traits to influence the rice–wheat
productivity with PM addition in SS and MS soils. Sustained use of this organic waste
in agricultural lands seems to be an affordable solution for overcoming sodicityinduced
land degradation, and achieving developmental goals of environmental and
livelihood security.
