“…Furthermore, the K + ion plays a central role in photosynthesis and exerts control over the opening and closing of stomata, especially in the context of stress conditions [126,127]. Potassium holds a crucial status as a significant macronutrient, bearing substantial roles within plants such as osmoregulation, regulation of membrane potential, cotransport of sugars, stress adaptation, and growth [128]. Its physiological functions encompass pivotal aspects such as the regulation of stomatal behavior, photosynthesis, and water uptake [124].…”

Although chemical fertilization has been excessively used for a high yield of fruit trees, it causes many problems such as nitrate accumulation, soil deterioration, and food safety and quality decline; therefore, the dependency on the usage of biostimulants has become paramount when aiming to reduce the usage of chemical fertilizers, improve the fruit quality, and increase the shelf life of the fruits. The present experiment was conducted during the 2021–2022 seasons to study the effect of the foliar of yeast extract (YE), fulvic acid (FA), moringa leaf extract (MLE), seaweed extract (SWE), and nano-potassium (K NPs) alone or after combining each one of them individually with K NPs on the yield and fruit physical and chemical characteristics of date palm cv. Samani. The results show that the application of 0.2% YE + 0.02% K NPs led to the highest results in yield, bunch weight, fruit weight, flesh weight, fruit content from soluble solids, total and reduced sugars, VC, total chlorophyll, and carotene. Additionally, the results also demonstrate that the application of 0.4% SWE + 0.02% K NPs, 0.4% FA + 0.02% K NPs, and 6% MLE positively affected the previously mentioned measurements compared with the control or the other sprayed treatments.

“…Potassium could be involved in the transportation and accumulation of sugars in fruit [73], and it is important in the regulation the osmotic pressure, preserving the cell membrane's turgidity and its potential protein synthesis [74]. Potassium is one of the vital elements because it is a constituent of the plant structure and has regulatory functions: protein synthesis, carbohydrate metabolism, enzyme activation, stomatal regulation, photosynthesis, increases in abiotic stress tolerance, membrane potential regulation, transport of sugars, stress acclimatization and plant growth [75][76][77]. Under salinity conditions, K + sustains ion homeostasis and controls the osmotic balance [78,79] and manages the stomatal opening under drought conditions and assists plants to acclimate under water stress [80].…”

To study the effect of potassium nitrate, calcium nitrate and kaolin (Aluminum silicate) on pomegranate cv. Wonderful, this study was conducted during 2020–2021 to investigate the possibility of minimizing the percentages of sunburn and fruit cracking and ameliorating the yield and fruit quality of pomegranate during the aforementioned period. Four sprays consisting of potassium nitrate at 1%, 2% and 3%, calcium nitrate at 2%, 3% and 4%, kaolin at 2%, 4% and 6% and water only (control) were sprayed on pomegranate trees during May, July, and August. The results showed that through spraying the fruit at set percentages, fruit yield was greatly increased through the spraying of potassium nitrate, calcium nitrate and kaolin, particularly the application of potassium nitrate at 3% and 4% and kaolin at 6% as opposed to than the other percentages. In addition, the percentages of fruit cracking and sunburn were markedly lessened by the application of calcium nitrate at 4% and 6% and also by kaolin at 6%. Moreover, the fruit content from TSS, total sugars and anthocyanin, was improved through the spraying of potassium nitrate at 2% and 3%, whereas the fruit weight and firmness were improved by the application of calcium nitrate at 4% and kaolin at 6%.

Attempt to increase soybean production while maintaining soil health can be done by utilizing biofertilizers. However, the application of biological fertilizers on Inceptisols which tend to be acidic often go to meet the problems in its effectiveness. So it is necessary to maintain the effectiveness of inoculants through the selection of appropriate carrier materials. The experiment aimed to determine the effect of the application of Phosphate Solubilizing Bacteria (PSB) in carrier materials from agricultural waste (molasses, coconut water, and bran) to increase BPF viability, growth and yield of soybean (Glycine max L.) on Inceptisols in Jatinangor. The experimental design used was a randomized block design (RBD) consisting of a control treatment (without BPF inoculant), BPF without organic matter; BPF combined with three types of organic matter (each: molasses, coconut water, and rice bran and their mixtures). Experimental results showed that coconut water and rice bran could potentially maintain the viability of the BPF population. Coconut water could significantly increase the number and weight of seeds per soybean plant, with an increase in yield of 41.176% and 18.823%, respectively. Coconut water is an organic substance that has the most potential as a stimulant material compared with molasses or bran.ABSTRAK Upaya untuk meningkatkan produksi kedelai sekaligus mempertahankan kesehatan tanah dapat dilakukan dengan memanfaatkan pupuk hayati (biofertilizers). Namun aplikasi pupuk hayati pada Inceptisol yang cenderung masam sering mengalami kendala dalam efektifitasnya. Sehingga perlu upaya untuk menjaga efektifitas inokulan melalui pemilihan bahan pembawa yang tepat. Percobaan ini bertujuan untuk mengetahui pengaruh aplikasi Bakteri Pelarut Fosfat (BPF) dalam bahan pembawa dari limbah pertanian (molase, air kelapa, dan dedak) untuk meningkatkan viabilitas BPF, pertumbuhan dan hasil tanaman kedelai (Glycine max L.) pada Inceptisols di Jatinangor. Percobaan dilakukan di rumah kaca kebun percobaan Fakultas Pertanian Unpad. Rancangan percobaan yang digunakan adalah Rancangan Acak kelompok (RAK) yang terdiri dari perlakuan kontrol (tanpa inokulan BPF), BPF tanpa bahan organik; BPF dikombinasikan dengan tiga jenis bahan organik (masing-masing: molase, air kelapa, dedak padi, dan campurannya). Hasil percobaan menunjukkan bahwa air kelapa dan dedak padi berpotensi dapat mempertahankan viabilitas populasi BPF. Air kelapa dapat meningkatkan jumlah dan bobot biji per tanaman kedelai secara signifikan, dengan peningkatan hasil masing-masing sebesar 41,176% dan 18,823%. Air kelapa merupakan bahan organik yang paling potensial sebagai bahan stimulan dibandingkan molase maupun dedak. Air kelapa mengandung glukosa, fruktosa, dan sukrosa, asam glutamat dan asam aspartat yang dapat berperan dalam memacu aktifitas BPF.
