Copper (Cu) is an essential micronutrient in plant nutrition, required in small amounts but critical for plant growth, yield, and crop quality. In modern agriculture, copper management is not only about supplying the element itself, but ensuring it remains available for plant uptake under diverse soil conditions. This is why chelated copper fertilizers such as …

1. Introduction Soil salinization is a major abiotic stress limiting agricultural productivity worldwide, particularly in coastal and irrigated regions. Rice as a salt-sensitive crop, is highly vulnerable to elevated salinity levels, especially during seedling and reproductive stages. Salt stress imposes both osmotic stress and ionic toxicity, resulting in impaired physiological metabolism, oxidative damage, and ultimately …

Leaf curling in greenhouse-grown Tomato during the mid-growth stage is a frequent but often misdiagnosed issue. While nutrient deficiencies are commonly suspected, this case study demonstrates that phytotoxicity caused by excessive application of plant growth regulators (PGRs) and foliar inputs can be the primary factor. This study analyzes field symptoms, identifies the root cause, and …

Introduction In modern agriculture, improving flowering, fruit set, and yield quality has become a key focus for growers worldwide. Biostimulants based on seaweed extracts have long been used for their natural hormone content, while 5-Aminolevulinic Acid (5-ALA)is gaining attention for its role in enhancing plant metabolism and photosynthesis. Combining these two components offers a novel …
