Nitrogen plays a crucial role in growth cycling and development, thereby influencing the plant growth and productivity. Understanding the interactions between nitrogen uptake with different irrigation regimes and source of nitrogen fertilizers could provide a valuable insight for optimizing tomato production. Hence, this study aimed to investigate the effect of nitrogen uptake on tomato production under different nitrogen fertilizer and irrigation regimes.
The field experiment was carried out during 2022-2023 in split plot design with two irrigation main plots treatments and five different nitrogen fertilizer subplot treatments. Irrigation treatments consisted of 0.8 and 1.0 IW/CPE ratio and the nitrogen fertilizer treatments comprised of conventional urea, neem coated urea, ammonium sulfate, nano-urea and vermicompost.
A higher nitrogen uptake was observed in the treatment combination of 0.8 and 1.0 IW/CPE ratio with vermicompost and nano-urea fertilizer applied treatments. Additionally, optimal irrigation conditions positively influenced nitrogen uptake and subsequent tomato fruit yield. This finding emphasizes the importance of considering nitrogen uptake when determining nitrogen fertilizer rates and irrigation management strategies for tomato production.
