Abstract

As a result of the increase in global temperature, cowpeas have been predicted to be one of the crops to face more frequent exposures to heat stress. This study investigates the effect of heat stress on stress-tolerant cowpea cultivars (Ifebrown-IF, Danila-DN, and Alokalocal-AK) from seed germination to early vegetative growth. Cultivars were exposed to different temperature regimes (27±3°C, 37±3°C) for 40 days and nights. IF and DN cultivars had early seed germination at both temperature regimes in comparison to the AK cultivar, which had delayed germination at 27±3°C. At the early vegetative growth stage, increased proline content, reduced oxidative stress, relative leaf temperature, stomatal conductance, reduced transpiration rates, and photosynthesis rates shifted each cultivar to the temperature of interest. Both temperature regimes favored DN and AK cultivars, while only 27±3°C supported IF cultivars, with evidence in their chlorophyll content, leaf area (LA), plant height (PH), fresh-shoot weight (FSW), and dry-shoot weight (DSW) in comparison to IF cultivars that had poor growth at 37±3°C. Thus, temperatures of interest are important to ensure tolerance of specific cowpea cultivars from seed germination to early vegetative growth under heat stress.

Abstract

The dairy sector, a fundamental component of the global food ecosystem, has witnessed notable expansion due to technological innovations and shifting consumer preferences. Nonetheless, the management of dairy waste poses a significant challenge, with inadequate treatment resulting in severe environmental repercussions, including aquatic pollution, eutrophication, and ecological deterioration. This research examines the physicochemical characteristics of effluents from two dairies in Varanasi—Parag Industrial Dairy and Ganga Local Dairy. Parameters such as pH, dissolved oxygen, biological oxygen demand (BOD), chemical oxygen demand (COD), hardness, and nutrient concentrations were evaluated using standardized methodologies. The results indicated substantial deviations from prescribed standards, particularly for ammoniacal nitrogen, COD, BOD, as well as oil and grease concentrations, highlighting deficiencies in existing treatment protocols. The findings accentuate the necessity for enhanced effluent management strategies to ensure compliance with environmental regulations and promote sustainability. Additionally, this research underscores the potential applicability of treated effluent for agricultural use, warranting further investigation into optimal dilution ratios and microbial interactions to maintain ecological equilibrium and sustained productivity.
