“…The results of the present study were in line with the findings of Choudhary et al [50]. The increment in the okra yield might be due to the growth-promoting abilities of the PGPR strains which were enhanced by their application in the form of organic carrier-based formulations [27,51].…”

Crop yields, soil fertility, and soil quality decline due to the overuse of chemical fertilizers and other agrochemicals. The damaging effects of these agrochemicals on the environment can be minimized by integration with eco-friendly approaches, i.e., biofertilizers. These eco-friendly biofertilizers containing plant growth-promoting rhizobacteria, (PGPR) not only solubilize mineral nutrients for crop uptake but also release phytohormones for their growth improvements. The objective of this research is to use these PGPR’s capacity to promote growth in order to increase okra production. For this purpose, different organic carriers were used, i.e., Press mud, Charcoal, Biochar, Peat, and Compost for PGPR’s inoculation. Before being used as a consortium with various carrier materials, the pre-isolated and characterized PGPR strains (AN-35, ZM-27, and ZM-63) were tested for compatibility against one another. The PGPR consortium and carriers were applied in the following treatments, i.e., T0: (control), T1: PGPR, T2: Peat + PGPR, T3: Pressmud+ PGPR, T4: Compost + PGPR, T5: Charcoal + PGPR, and T6: Biochar + PGPR in the present pot and field studies. Under the pot experiment, the results depicted that all treatments showed a significant increase in okra growth, nutrient contents, and yield of okra along with increasing the microbial biomass in the soil but the treatment containing PGPR consortium with peat caused the maximum increase. Similarly, the results of the field experiment also showed a significant increase under all treatments but the maximum increase in nutrient contents, growth attributes, and yield of okra was found under the treatment containing PGPR consortium with peat (T2). Therefore, this study recommends the use of peat and studied the PGPR consortium as a suitable carrier to develop carrier-based biofertilizers for sustainable okra production.

“…Muqtadir et al, (2019) found that, plant height of okra was significantly higher at 80 days after sowing from mixed of cow dung and inorganic fertilizer compared to other treatment. Kumar et al, (2019) reported that, combined application of organic and chemical fertilizers can increases plant height of okra. Hence, integrated nutrient management maintains organic matter in soil and improving nutrient and structural status of soils which influences vegetative growth and reproductive parameters of okra.…”

Integrated use of organic and inorganic fertilizers could improve both growth and yield of okra plant. The present study was carried out to evaluate the effect of organic and inorganic fertilizer on growth and yield parameters of okra (Abelmoschus esculentus L.) at experimental area of Noakhali Science and Technology University, Bangladesh during the period of 18th December, 2018 to 19th March, 2019 (Rabi season). In this experiment, “Arka Anamika” variety of okra was used. The experiment was laid out in Randomized Complete Block Design (RCBD) with four treatments viz. T1= INM (organic and inorganic), T2= Inorganic (NPK), T3= Organic (cowdung), T4= Control and three replications. Data were taken on the growth and yield parameters such as plant height (cm), number of leaves per plant, number of branches per plant, days to first flowering (days), number of fruit per plant, individual fruit weight (gm), fruit length (cm) and fruit diameter (cm). Among all treatments INM (organic and inorganic) was responsible for highest plant height (49.96 cm), maximum number of leaves per plant (22.33) and branches per plant (6.33), accelerated days to first flowering (39 days), increases the number of fruit per plant (14.33), individual fruit weight (24.89 gm), fruit length (15.5 cm) and fruit diameter (1.98 cm). So this study clearly indicated that, among all treatments INM (Organic and inorganic) performed the best and it will be suitable for okra production. Asian Australas. J. Food Saf.

“…Van der Eijk et al reported that the high content of P under cultivated land (maize) than of grass land soils could be due to the continuous application of phosphorus fertilizer applications. Indiscriminate use of inorganic fertilizers leads to nutrient imbalance in soil causing ill effect on soil health and micro flora (Choudhary et al 2015).…”

Soil is key resources upon which the functioning of all biological land use depends, and the most important component of sustainable agriculture with this view the study was conducted to assess physicochemical and biological properties of soil under different land use types in southern transect of Bengaluru. Fifty soil samples were collected from each land use system viz agriculture, horticulture, mulberry and plantation land use. The soil was examined for various physico-chemical and biological properties including sand, silt, clay, soil pH, organic carbon (OC), electrical conductivity (EC), available nitrogen (N), phosphorus (P) and potassium (K), exchangeable calcium (Ca) and magnesium (Mg), sulphur (S), micronutrients (Zn, Fe, Mn, Cu and B) and heavy metals (Cd, Cr, Ni and Pb) and dehydrogenase activity (DHA). The results of the experiment reveled that soil pH varies from strongly acidic (4.23) to strongly alkaline (8.56), low (0.39 dS m-1) to high (0.88 dS m-1 ) EC content. Whereas OC content under different land use systems was in the medium range. The significantly higher soil OC, available N, P2O5 and K2O recorded in agriculture land use. The exchangeable Ca (10.71 c mol (p+) kg-1) and Mg (7.96 c mol (p+) kg-1) recorded significantly higher in agriculture land use. Plantation land use marked significantly higher Fe (12.99 ppm) and Mn (8.51 ppm) contents followed by mulberry (12.16 ppm and 8.23 ppm), Whereas Zn and B were found high in agriculture land use system (0.80 ppm and 0.85 ppm) compare to other land use systems. Heavy metals (Cr, Pb and Ni) were found nonsignificant. Whereas Cd was found significantly different among the land-use system and found high in horticulture land use system (0.049 ppm). Conclusively, land use change affects soil physico-chemical and biological properties.
