Exogenous applied Allium sativum alleviate salinity induced stress in late sown wheat and alfalfa
Journal Title: Scientia Agriculturae - Year 2015, Vol 11, Issue 2
Abstract
Allium sativum potential as medicine in homeopathy and allopathy have significant explored while its allelopathic potential remained unexplored. To investigate its stimulatory/inhibitory effect in late sown wheat and alfalfa crop under salinity stress, two pot experiments were performed under arid land climate in 2014-15. Salt stress was applied after four week of crop emergence, as saline water irrigation with concentrations of 4000 ppm and 6000 ppm along with control of 1000 ppm. To rectify the salt induced stress, exogenous application of garlic extract as foliar spray was used at reproductive stages booting flowering and grain filling. Garlic extract was applied at different concentrations viz., 10%, 20% and 30% of pure garlic extract. A distil water (0% garlic extract) control was also set at each salinity level for both crops. Statistical analysis of the data revealed significant effect of salinity and garlic extract for each crops on growth, yield and root attributes except root length and root number in alfalfa that was non-significant for salinity stress. Interaction of salinity × garlic extract were non-significant for leaf area and root number for both experiments. Maximum concentration of exogenous foliar applied garlic extract reported an improvement of 70-77% in plant height, 47-85% in dry biomass accumulation, 08-26% in leaf attributes and 46-74% in root attributes at severe salinity stress level. Wheat spike length, spikelet per spike and per plant grain weight were also improved by this treatment. Garlic extract at 30% concentration can be adopted as saline water irrigation induced salinity stress regulating treatment in wheat and alfalfa crop.
