“…There were significant positive relationships between LAI and tuber yield, REN and net return, which can be used to explain that the highest tuber yield, REN and net return under the W1N2 treatment, were due to the LAI being the greatest. A previous study reported similar results, showing a strong correlation between yield and LAI [ 36 ]. Therefore, LAI was the primary reason for the increase in tuber yield, N recovery efficiency and profit, suggesting LAI can be used as one of the important indicators to guide potato breeding for high yield, high efficiency and high profit.…”

Soil-based irrigation and the partial substitution of chemical fertilizers with manure are promising practices to improve water and nitrogen (N) use efficiency. We hypothesize that their combination would simultaneously benefit potato production, tuber quality and profitability. A two-year experiment was conducted in semiarid northern China to investigate the combined effects of three water treatments [rainfed (W0), soil-based irrigation (W1), conventional irrigation (W2)] and three N treatments [no N (N0), chemical N (N1), 25% manure substitution (N2)] on these indicators, and to perform a comprehensive evaluation and correlation analysis. The results showed that water and N treatments separately affected all indicators except vitamin C content. Compared to W2, W1 significantly increased water productivity by 12% and irrigation water use efficiency (IWUE) by 30% due to 10% lower evapotranspiration and 21% lower water use. However, W1 and W2 negatively affected crude protein content. Conversely, this was compensated by the combination with N1 and N2. There were slight differences between N1 and N2 for all indicators on average across water treatments, while under W1, N2 significantly increased leaf area index (LAI) and N recovery efficiency (REN) by 18% and 29.4%, respectively, over N1. Also, comprehensive evaluations showed that W1N2 performed best, with the highest tuber yield, profit and acceptable quality. This can be explained by the increase in LAI, IWUE and REN due to the positive correlations with tuber yield and net return. Consequently, soil-based irrigation combined with 25% manure substitution had complementary effects on tuber quality and synergistic effects on potato productivity and profitability.

“…This study also reveals that the number of bolls on cotton plants is directly affected by the interaction between sowing dates and phosphorus levels (Ahmad et al, 2019;Sun et al, 2022Sun et al, , 2023. Understanding this relationship can help in crop management to encourage more boll formation, which, in turn, can lead to higher cotton yield (Khan et al, 2019;Li et al, 2022;Guo et al, 2023). These findings can guide farmers and agronomists in tailoring their crop management strategies to suit local conditions and resource availability.…”

This study assessed the effects of sowing dates and phosphorus levels on cotton performance in Chato-Msilale village in Chato District, Tanzania. The soil analysis revealed that field exhibited slightly acidic soil with normal electrical conductivity but suffered from severe deficiencies in total nitrogen and organic carbon. The same field presents common issue of low cation exchange capacity, indicating limited nutrient-holding capacity. Furthermore, both fields displayed very low levels of total nitrogen (<0.1%), signaling a nitrogen deficiency. Available phosphorus was rated as medium (16.8 mg kg−1 soil). Trace elements fluctuated and could be managed based on specific crop requirements. The factors at different levels were: (1) sowing dates – (i) 25th November 2022, (ii) 15th December 2022, and (iii) 4th January 2023; and (2) Phosphorus levels – (i) control, (ii) 20 kg P ha−1, (iii) 40 kg P ha−1, and (iv) 60 kg P ha−1. Regarding cotton growth and yield, sowing dates significantly (p < 0.001) influenced plant height, gin turnout, lint yield, number of bolls per plant, and boll weight while phosphorus levels did not exhibit significant effects. Earlier sowing dates resulted in higher yields, albeit with variations in yield components. Interactions showed that growth and yields were only numerically higher in the middle sowing date at higher levels of phosphorus applied. Overall, these insights offer valuable guidance for optimizing cotton cultivation in Chato District, emphasizing the importance of selecting appropriate sowing dates for improved yields.

“…The negligible positive relationship between okra yield and growth parameters such as plant height and number of nodes suggests a different viewpoint to the reports of Echezona et al ( 2010) that taller plants and more nodes give a better chance for more okra pods. Generally, morphological attributes such as leaf area and the number of leaves directly correlate with the plant photosynthetic capacity, which determines the yield (Li et al 2022;Yang et al 2019). Also, stem girth could be a reliable growth indicator since the plant stem is a major sink organ for carbon assimilates from the source leaf (Kanai et al 2011 La cohabitation des adventices avec les cultures ne pose pas toujours des problèmes.…”
