Documentation the relative influence of ecological dynamics on species diversity patterns can help us better understand spatial distribution patterns and devise a systematically comprehensive base for carrying out environmental explorations. The current attempt aimed at exploring the distribution patterns, diversity and richness of wild grasses with respect to climatic dynamics in the Gujrat district of Punjab, Pakistan. For this purpose, we applied the randomized sample method and sampled a total of 90 sites across the Gujrat district between 2019 and 2021 to document data on wild grasses and related ecological conditions. After assessment of the significant value index of each grass species with ecological records, we evaluated the data by ordination and cluster analysis. A total of 57 wild grasses from 37 genera were documented from the Gujrat district. The leading genera were Brachiaria, Cenchrus and Setaria, each accounting for 7.02% of all documented species, followed by Aristida and Panicum, each representing 5.76% of the species. Dactyloctenium, Dichanthium, Eragrostis, Polypogon, Poa and Saccharum each accounted for 5.26% of the species, and Digitaria, Pennisetum, Eragrostis, Chrysopogon Poa and Setaria each accounted for 3.51% of the species. Other genera each had a single species. Among all grasses, 75.44% of the species were native and 24.56% species were exotic and introduced to the study area. The leading life forms were therophytes (56.14%), followed by hemicryptophytes (42.11%) and geophytes (1.75%). Microphylls, with a 54.39% share, dominated the leaf size spectra of the wild grasses flora in this research. Other frequent classes included nanophylls (21.05%), macrophylls (19.3%) and leptophylls (5.26%). Flowering phenology of wild grasses showed that mainly species at the flowering phase were recorded during the months of June to August (40.35%) and July to September (19.29%). By applying Ward’s agglomerative clustering method, we classified the ninety transects into four major groups. Ordination analysis showed that different ecological factors had significant (p ≤ 0.002) effects on vegetation relations. The present endeavor provides a basic way to understand the impacts of ecological variables on the structure, diversity, composition and associations of wild grasses, which are helpful to improve the scientific-informed conservation and management measures for the environmental reestablishment of degraded habitat in the studied region.

Extreme heat, droughts, pests, diseases, and short bursts of heavy rain make potato production unsustainable. This unfavorable environment negatively affects potato productivity and yield levels. Within the next few years, conditions will likely deteriorate even more. In potato cultivation, straw mulching has been shown to increase yields by promoting the growth of beneficial bacteria in the soil. Mulching improves soil humidity, decreases transpiration, and cools the soil in dry and hot regions. There is a global decline in potato yields per hectare due to poor nutrient management, moderately humid years, and high disease pressure caused by Phytophthora infestans and Alternaria species. Farmers must take cultivation measures to achieve economic efficiency and adequate yields. A range of practices contributes to better potato yields and productivity, such as the use of appropriate fungicides, planting high-yielding varieties, and increasing row spacing. These practices complicate cultivation and affect profits. Furthermore, inorganic nitrogen in the soil regularly causes acidification, eroding soil fertility. As a result of land preparation, straw residues from rice and maize are collected from the field and destroyed or burned, which depletes nutrients and pollutes the air. Returning these residues to the soil, however, can improve its quality. Integrating rice and maize straw mulching into potato cultivation practices can enhance agricultural sustainability, productivity, and yield. This review will focus on using rice and maize straw mulching in cultivating potatoes. Straw mulching promotes sustainable potato growth, increasing productivity and quality while minimizing reliance on chemical inputs. Such practices can mitigate the need for synthetic fertilizers to enhance sustainable agriculture, ensure long-term growth, improve soil health, increase yields, and promote sustainable agriculture.
