Statistical Analysis of the Effects of Spacing and NPK Fertilizer Application on Growth and Yield of Tomato

Tomatoes are a vegetable crop of high economic significance worldwide, and agronomic practices should be optimized to achieve maximum productivity. A search on Scopus indicates that there are more than 103, 900 articles from 1924 to 2025. This interest incites the development of a bibliometric analysis focused on the use of fertilizers. VOSviewer tool is also used to show the most authors and countries, and the cooperation between institutions. The major trusts of the paper are to determine the effect spacing and influence of varying fertilizer application on tomato growth and yield. Analysis of Variance (ANOVA) was performed on the data at a 5 percent probability level. The findings showed that the spacing and application of NPK fertilizer played a significant role in the growth and yield characteristics. The results of the study have shown that spacing had a significant effect on the growth parameters of the tomato plant, while fertilizer levels strongly affect both tomato growth and yields.
