“…This region has shallow to moderately shallow depth soils which can be grouped into four categories as red, brown, grey Vertosols, sandier soil types [19]. Most of the soil is of black cotton type which is good for the cultivation of wheat, green gram, soyabean, rice, and groundnut [20]. The land use pattern, highlighting the study locations, is illustrated in Fig.…”

Extensive industrialization, urbanization, and excessive use of chemicals in agricultural practices have caused soil quality depletion and reduced its nutritional value. In this context, the present study aimed to evaluate the effect of vermicompost (VC) on different soil properties such as pH, electrical conductivity, soil organic carbon, soil organic matter, total phosphorus, and bulk density to understand the soil enrichment for different land use patterns i.e., agriculture soil (AS), forest soil (FS) and barren soil (BS). The collected soil samples were mixed with VC in different proportions (1:1, 1:2, 1:3, 1:4, and 1:5) and analyzed in terms of aforementioned parameters. Among the investigated soils, the highest microbial biomass was observed for FS samples and noted in the range of 6 – 8 mg/gm of soil. All the original soils, supplemented samples, and VC were also subjected to plant growth analysis. The soil quality index (SQI) was determined using principal component analysis for selected soil samples and resulted mixtures obtained from soil and various proportions of VC. Among all samples, highest SQI was observed as 0.785 for VC. Overall, the result of the study showed that vermicompost can be a potential substitute of chemical fertilizers, thus improving the soil quality and crop yield.

“…Nutrition in plants is essential to obtaining the desired yield. Plant production requires all essential nutrients to develop all functions that provide a product with known quality (Rajendran et al, 2009). Because each distinct nutrient plays a strategic function in the plant, there is a physiological expression caused by its particular depletion (van Maarschalkerweerd and Husted, 2015).…”

“…In addition, a B deficiency represses root and shoot elongation. The terminal apexes of shoots become necrotic because of inhibited cell division, deforming fruit and flower development; these parameters hamper metabolic communication (Rajendran et al, 2009;Marschner, 2012;Taiz et al, 2017).…”

“…A well-made visual diagnosis of the nutritional state of a given plant should include the mobility and physiology of the nutrient, its spatial distribution and location of the symptoms, along with senescence symptoms of the leaves (Gómez, 2012). Nutrient deficiency symptoms are widely used to determine the nutrient demands of a crop and to clarify nutritional disorders, especially when they are specific for a certain nutrient element (Rajendran et al, 2009). The first study on visual deficiency symptoms of nitrogen (N), phosphorus (P) and potassium (K) in feijoa was published by Buitrago et al (2021).…”

“…Interestingly, neither Ca nor B had a significant reduction in shoot production. Both calcium and magnesium are widely known as cooperative nutrients that have a complementary role (Rajendran et al, 2009). Differences in cell wall chemistry based on Mg and Ca concentrations allow plants to execute distinct stoichiometric equations.…”

Nutrient deficiency symptoms are widely used to determine the nutrient demands of a crop and to clarify nutritional disorders, especially when they are nutrient specific. Until now, a calcium (Ca), magnesium (Mg) and boron (B) deficiency experiment has not been carried out on feijoa, and diagnostic symptoms have not been described. For this reason, 9-months-old ‘Quimba’ feijoa plants were studied using the missing nutrient method. A modified Hoagland and Arnon solution was applied for each treatment, leaving out one element in each treatment. The treatments were: (1) complete fertilization (control); (2) complete fertilization -Ca; (3) complete fertilization -Mg; (4) complete fertilization -B; and (5) without fertilization (negative control). Deficiency symptoms in the plants were described, and photographic records were made. The Ca deficiency was noted early in the shoot tips and later in fully-expanded, young leaves. The Mg-deficiency was observed in older and fully-expanded leaves, mainly as interveinal chlorosis, while the B deficiency generated a variety of symptoms, interveinal and total chlorosis in fully and not fully-expanded leaves and a mosaic of symptoms in adult leaves. For the growth components, the Mg deficiency reduced the number of apical shoots, while the Ca- and Mg-deficiencies reduced the seedling growth rate significantly. For future experiments, the authors suggest an experiment period longer than 102 d to achieve more conclusive results.
