Proper irrigation and fertilization are essential for achieve high tuber yield and quality in potato production. However, the high cost of these inputs necessitate optimization of their use to improve both water use efficiency and crop productivity. This study aimed to investigate the impact of irrigation and nitrogen fertilization on potato yield, quality and water use efficiency. The research included different drip irrigation treatments (100%, 66%, and 33% of field capacity) and nitrogen levels: 0 (N0), 100 (N1), 200 (N2), 300 (N3), 400 (N4) and 500 (N5) kg N ha−1. The results indicated that potato yield and growth were more sensitive to irrigation treatment than nitrogen levels. Full irrigation with 300 kg N ha−1 produced the highest total tuber yield, while low irrigation treatments resulted in significantly lower yields. In contrast, the 66% field capacity irrigation treatment consistently had the highest water use efficiency in both years of the study. Furthermore, the study showed that the quality characteristics of the tubers were negatively impacted by full irrigation treatments compared to low irrigation. These findings suggest that with appropriate irrigation and nitrogen application, potatoes can be produced with acceptable yields while conserving water and minimizing nitrogen use. This research emphasizes the importance of optimizing inputs to improve water use efficiency and yield productivity while reducing water. As a result, obtaining useful information on crop management for farmers to make informed decisions may be possible by achieving optimal irrigation and nitrogen levels.

“…Increasing irrigation during the growth period rapidly increased the soil moisture, and appropriate soil moisture environment would accelerate crop water metabolism, open leaf stomata through signal transmission, increase crop transpiration, and increase water consumption [52]. Kaur et al [53] revealed that crop ET first rose and then declined with increasing fertilizer application, obtaining the largest value at 150 kg ha −1 nitrogen application. Our study reached similar conclusions.…”

Irrigation, fertilization, and variety are important factors affecting potato production in northwest China. Field experiments (2021 and 2022) were performed to investigate the effects of irrigation and fertilization on the plant growth and soil microbial population of different potato varieties. Three irrigation levels were used, i.e., 100% ETc (W1), 80% ETc (W2), and 60% ETc (W3), with ETc standing for crop evapotranspiration. Three fertilization levels were used (N-P-K), i.e., 240-120-300 kg ha−1 (F1), 180-90-225 kg ha−1 (F2), and 120-60-150 kg ha−1 (F3). Three variety types were used, i.e., Feiurita (V1), Longshu 7 (V2), and Qingshu 9 (V3). These factors significantly influenced tuber yield (TY), net income (NI), and water productivity (WP). TY, NI, WP, total nitrogen accumulation (TNA), and nitrogen use efficiency (NUE) peaked at F2. Fertilization significantly impacted soil bacteria quantity (SBQ), fungi quantity (SFQ), and actinomycetes quantity (SAQ). TY, NI, SBQ, SFQ, and SAQ were highest at W2. Soil microbial population was strongly correlated with TY, NI, WP, TNA, and NUE. Comprehensively, this study suggests that irrigation that is varied from 248 to 266 mm, and fertilization (N-P-K) that is varied from 149.09-74.55-186.36 to 212.73-106.36-265.91 kg ha−1 can promote the potato industry’s sustainable development and provide important references for the optimal field management of potato cultivation in northwest China.

“…This in turn helps in optimizing crop yields with higher drought tolerance [82]. In several studies, soil nitrogen (N) level was positively related to water use efficiency [83][84][85]. Potato cultivation is quite demanding in inorganic nutrients and adequate fertilization is a key factor for maximizing yield and producing tubers of high quality [86].…”

Potato (Solanum tuberosum L.) is the fourth most important food crop in the world with annual production of nearly 300 million tonnes. However, significant amount of the product (20–25%) is compromised to postharvest losses. Significant amount of the product (20–25%) is compromised to postharvest losses, therefore, alleviation of food security problems can be achieved through reduction in postharvest losses. Role of plant growth-promoting (PGP) microbes for the enhancement of potato production has been subject of extensive research. However, their impact on postharvest quality of horticultural crops has largely been unexplored, with limited research conducted on plant–microbe interactions in postharvest crops and their impact on storage stability. Although, microbial control has emerged as one of the most promising alternatives to chemical fungicides in several studies, however, significant research and development are required in development of sustainable microbial bio formulations for effective management of the crops under storage, in keeping with the quality of the produce. Therefore, manipulation of the bacterial microbiome, specially during crop storage, might provide microbial solutions as cleaner and sustainable alternatives to chemicals for plant production along the whole food chain. This chapter would elucidate functional analysis of the dynamics and potential of microbial live formulations for reducing the crop losses due to various diseases and status of the crop
