“…The current research revealed that with an increasing number of N and P fertilizer applications, values of specific gravity decreased. The results of the current study correlate with previous reports [ 56 , 57 ]. Our research demonstrates a relationship between potato yield and balanced application of PGPB coated N and P biofertilizers which indicates MFA as an effective approach to enhance potato production, with reduced water pollution.…”

Background Potato serves as a major non-cereal food crop and income source for small-scale growers in Punjab, Pakistan. Unfortunately, improper fertilization practices have led to low crop yields, worsened by challenging environmental conditions and poor groundwater quality in the Cholistan region. To address this, we conducted an experiment to assess the impact of two fertilizer application approaches on potato cv. Barna using plant growth-promoting bacteria (PGPB) coated biofertilizers. The first approach, termed conventional fertilizer application (CFA), involved four split applications of PGPB-coated fertilizers at a rate of 100:75 kg acre–1 (N and P). The second, modified fertilizer application (MFA), employed nine split applications at a rate of 80:40 kg acre–1. Results The MFA approach significantly improved various plant attributes compared to the CFA. This included increased plant height (28%), stem number (45%), leaf count (46%), leaf area index (36%), leaf thickness (three-folds), chlorophyll content (53%), quantum yield of photosystem II (45%), photosynthetically active radiations (56%), electrochromic shift (5.6%), proton flux (24.6%), proton conductivity (71%), linear electron flow (72%), photosynthetic rate (35%), water use efficiency (76%), and substomatal CO2 (two-folds), and lowered non-photochemical quenching (56%), non-regulatory energy dissipation (33%), transpiration rate (59%), and stomatal conductance (70%). Additionally, the MFA approach resulted in higher tuber production per plant (21%), average tuber weight (21.9%), tuber diameter (24.5%), total tuber yield (29.1%), marketable yield (22.7%), seed-grade yield (9%), specific gravity (9.6%), and soluble solids (7.1%). It also reduced undesirable factors like goli and downgrade yields by 57.6% and 98.8%, respectively. Furthermore, plants under the MFA approach exhibited enhanced nitrogen (27.8%) and phosphorus uptake (40.6%), with improved N (26.1%) and P uptake efficiency (43.7%) compared to the CFA approach. Conclusion The use of PGPB-coated N and P fertilizers with a higher number of splits at a lower rate significantly boosts potato production in the alkaline sandy soils of Cholistan.

“…This could be attributed to the enhanced availability of nutrients to the crop which may have resulted in increased photosynthetic efficiency and increased metabolic activities of the plant with an increase in water level and fertilizer rate. Similar findings were obtained by Sriom et al, (2017) reported that vegetative growth increased with increasing fertilizer levels of N. In addition, Ahmed et al, (2009) indicated that the use of ammonium nitrate as a source of N fertilization resulted in a significant increase in all vegetative growth traits, while urea gave the lowest values. In the other hand, Zelalem et al, (2009) reported that N fertilization did not significantly influence the number of stems in potato .…”

In potato cropping systems, nitrogen and water availability are essential factors for production. In this regard, water and nitrogen fertilizers management are considered a challenge in potato production. Therefore, this study aimed to explore the effect of N source and rate in collaboration with different irrigation water levels on the vegetative growth, yield, and quality of potato tubers. To achieve this objective, a pot experiment was conducted during season 2020/2021 at Soil and Water
