The effects of drought stress and zeolites on the protein and mineral nutrients of Lathyrus sativus.
The study conducted by Alireza Pirzad and Sevil Mohammadzade, published in the International Journal of Biosciences, investigates the impact of drought stress and the application of zeolites on the protein and mineral nutrient content of Lathyrus sativus (grass pea). The research aimed to assess how varying levels of irrigation and zeolite application affect the leaf nitrogen, phosphorus, potassium, and protein content of the plant.
The experimental design involved two irrigation levels (field capacity and 50% field capacity) and four zeolite application rates (0, 10, 20, and 30 tons/ha). The results indicated that drought stress significantly reduced the leaf nitrogen, phosphorus, potassium, and protein content. Conversely, the application of zeolite mitigated these negative effects, particularly at the highest application rate of 30 tons/ha, which resulted in the highest leaf nitrogen (2.17%), phosphorus (0.2%), and protein yield (0.07 g/plant).
The study highlights the importance of zeolite as a soil amendment that can enhance nutrient uptake and improve plant resilience under drought conditions. The findings suggest that zeolite application can extend irrigation intervals for Lathyrus sativus, making it a viable strategy for improving crop yield in arid regions.
This research paper is significant in the field of agronomy and sustainable agriculture, particularly in addressing the challenges posed by drought stress in crop production. The research contributes to ongoing discussions about improving water use efficiency and nutrient management in agriculture, especially in arid and semi-arid regions where water scarcity is a critical issue. By demonstrating the beneficial effects of zeolite on nutrient retention and plant growth under drought conditions, the study offers practical insights for farmers and agricultural practitioners seeking to enhance crop resilience and yield. The findings can inform future research and agricultural practices aimed at mitigating the impacts of climate change on food security.
