“…On the other hand, for the high stratum, the analysis of variance found no specific differences between the treatments (Figure 3). The results of the relative chlorophyll content coincide with those reported in other experiments with macronutrient deficiencies in Capsicum annuum L. [28] and Coffea arabica L. plants [7].…”

The common fig is an edible fruit which is appreciated for its organoleptic characteristics and high commercial value. Several factors, including mineral nutrition, affect fig production. Macronutrients fulfill specific functions in the metabolism of plants, affecting some functions when they are at low levels. So, in the present investigation, the visual symptoms of nitrogen, phosphorus, potassium, calcium, and magnesium deficiencies were identified and characterized, as well as their effects on vegetative growth and the concentration of minerals in fig tree tissues, using the missing element technique in a controlled hydroponic system. N was the element that most affected vegetative growth, causing smaller stem diameter, leaf area, and dry weight. Treatments without P and K followed. In addition, significant differences were found in the mineral concentration in leaf, stem, and root, with various interactions of antagonism and synergism observed according to the absence of each element.

“…Initial symptoms of N deficiency were observed on the fifth day after the plants received the nutrient solution with N omission, indicating the importance of this macronutrient for the crop. Similar behavior was observed in bell pepper (Capsicum annuum) by Silva et al (2019), who found that the first symptom of deficiency was caused by the absence of nitrogen in the nutrient solution.…”

Aspects related to tomato (Solanum lycopersicum L.) mineral nutrition are important for the production of quality fruits. The cherry tomato (Solanum lycopersicum var. cerasiforme) is an alternative for most producers due to its high market value, greater productivity and good acceptance by consumers. The objective with this study was to evaluate the nutritional status of cherry tomatoes cultivated in nutrient solution under omission of macronutrients. The experiment was conducted in a completely randomized design, with seven treatments: complete nutrient solution and omissions of N, P, K, Ca, Mg and S, with five replicates. Visible symptoms of nutritional deficiency were observed in the following order of omission: at 5, 12 and 20 days after transplantation in plants under omission of N, P and K, respectively. Conversely, there were no visible symptoms of deficiency under omissions of Ca, Mg and S. The sequence of growth limitation, determined based on the shoot dry mass of cherry tomato plants, was: N>P>S>Mg>Ca>K. The omission of a nutrient, besides reducing its content in the leaf tissue, causes imbalance between the other nutrients, influencing the parameters of growth and production, leading to morphological manifestations in cherry tomato.

“…This fact shows that plants need macronutrients, such as N, P, and K, to support their growth. The availability of these macronutrients in sufficient quantities produced plant leaves that grew well so they could carry out photosynthetic activities properly [13] to support plant growth. Bioorganic fertilizers and a mixture of macro and micronutrients provide additional macronutrients for chili plants.…”

The fruit set and yield of cayenne pepper grown during the rainy season (off-season) is relatively lower than during the dry season. This study aimed to assess the effectiveness of some foliar fertilizers in improving the fruit set and yield of cayenne pepper grown off-season on dryland. An experiment was conducted during the rainy season of 2021/2022 on a dryland area of Gumantar, North Lombok, Indonesia. Four foliar fertilizers and one control were tested on two varieties of cayenne pepper. The foliar fertilizers were: bio-organic (Pomi), silicate and boron (X-ZO), micronutrients (Meroke Fitoflex), and a mix of macro and micronutrients (Bayfolan). The two varieties were: hybrid (Dewata 43) and open-pollinated (Sret). The treatments were arranged in a factorial randomized block design with three replications. After five harvests, the results showed no interaction between foliar fertilizer and variety in affecting fruit set and yield. The foliar fertilizers improved the fruit set and yield of cayenne pepper. The most significant improvement was the bio-organic fertilizer with 10.6% and 42.5 % for fruit set and fruit weight per plot, respectively, compared to the control treatment. The hybrid variety yielded 822.5 g plant−1, higher than the open-pollinated ones with 632.3 g plant−1.
