“…Inorganic fertilizers play an important role in high yields of the earth, but nitrogen (N) is one of the nutrients absorbed by maize. Moreover, the cost of nitrogen fertilizer is very high, which will cause great losses to the agricultural environment (da Rocha Dias et al, 2020). Currently, about 50% of the population is dependent on nitrogen fertilizer for food, and 60% of nitrogen is used to produce three major crops: rice, maize, and wheat (Ladha et al, 2005).…”

Agriculture is the backbone of Pakistan's economy, highly depends on food crops. There is a huge gap between the products purchased and the actual products, which suffer from inadequate technology, inadequate resource use, inappropriate use of water and land, and inappropriate pests management studies, it's not just negatively affects production but also reduces production. Most farmers use synthetic chemicals to control pests, but they are often used in vain. In order to illustrate the main gaps and actual results of the main upland crops. The study examines the link between food security and GDP growth in Pakistan, including wheat, rice, sugarcane and maize, and water availability in Pakistan from 1999 to 2018. Periodic data are collected from the Pakistan Economic Survey (various sources). Use conventional miniature methods and refine Dickey-Fuller (ADF) testing to analyze crop data, and use Johansen aggregation testing to interpret results. Our research found that wheat, rice, sugarcane, and maize yields were positively correlated with Pakistan's agricultural GDP, while water supply was negatively correlated with Pakistan's agricultural GDP without significant correlation. Water resources related to climate change and the context of climate change will have a devastating effect on Pakistan's water resources. Therefore, the study suggests that the Pakistani government should provide major agricultural inputs on subsidies formulate policies, and launch new funding programs to develop and improve water availability.

IntroductionApplications of organomineral fertilizer (OMF) are important measures for developing organic agriculture in karst mountain areas. However, the influence of OMF on the structure and function of soil microbial diversity and their relationship with crop yield and quality are still unclear.MethodsBased on soil science, crop science, and high-throughput sequencing methods, we investigated the changes of rhizosphere soil microbial communities of Perilla frutescens under different fertilization measures. Then, the relationship between P. frutescens yield and quality with soil quality was analyzed.ResultsThe results showed that the addition of OMF increased the amount of total carbon and total potassium in soil. OF, especially OMF, improved P. frutescens yield and quality (e.g., panicle number per plant, main panicle length, and unsaturated fatty acid contents). Both OF and OMF treatments significantly increased the enrichment of beneficial microorganism (e.g., Bacillus, Actinomadura, Candidatus_Solibacter, Iamia, Pseudallescheria, and Cladorrhinum). The symbiotic network analysis demonstrated that OMF strengthened the connection among the soil microbial communities, and the community composition became more stable. Redundancy analysis and structural equation modeling showed that the soil pH, available phosphorus, and available potassium were significantly correlated with soil microbial community diversity and P. frutescens yield and quality.DiscussionOur study confirmed that OMF could replace CF or common OF to improve soil fertility, crop yield and quality in karst mountain soils.
