“…It was recorded that maximum acidity was found in the control treatment thereby decreasing the pH and it may be due to decreased cell size and cell division due to lighter turgor pressure and internal auxin content whereas minimum acidity was found in plants treated with potassium and this might be due to the function of potassium in the synthesis of more carbohydrates and their translocation from leaves to fruits and accumulation of sugars which enhanced the pH, making the juice less acidic and increased ascorbic acid with foliar application of potassium might be related with improved sugar metabolism and also due to role of potassium in activating the synthesis of ascorbic acid somewhere between D-Glucose to L-Ascorbate. The results were in line with Heshi et al, (2001), Khayyat et al, (2012), Thirupathi and Ghosh (2015) and Hamouda et al, (2015) in pomegranate, Dalal et al, (2017) and Vijay et al, (2016) in sweet orange cv.

“…Previous studies have shown various effects of different potassium forms on yield, fruit quality and postharvest fruit attributes, with contradictory findings according to methods and number of application, in addition to crop type and phenological stages [15,[22][23][24][25]. Exogenous application of an appropriate K form could allow for a higher yield, better quality and alleviate chilling injury during cold storage of different fruit species [26].…”

This is the first report to study the impacts of potassium sources on apricot fruit yield, quality and storability as a preharvest foliar application. Five sources of potassium (K-humate, K-sulphate, K-nitrate, K-silicate and K-citrate), plus water as a control treatment, were applied individually at 0.2% three times on ‘Canino’ apricot over the 2019 and 2020 seasons. The results showed that all potassium salts, applied foliarly, have potential to improve yield, fruit color, and some fruit physical attributes, such as: weight, size and firmness, as well as a reduced lipid peroxidation, accompanied by a low fruit malondialdehyde content reflected in a high tolerance during storage. The K-nitrate treatment was more effective in the improvement of fruit yield, preharvest quality parameters and keeping fruit postharvest quality characteristics from sharp decline during cold storage. Concerning fruit anatomy, K-nitrate and K-citrate showed thicker cuticle and epidermal parenchyma cell diameters, while the K-silicate induced the highest cell wall thickness. K-nitrate was the most economical, and could be recommended for apricot growers in the Nubaria region of Egypt.

“…Fertila merupakan pupuk yang baru dipasarkan di Indonesia mengandung unsur hara lengkap yaitu 12% N, 6% P2O5, 24% K2O, 2% MgO, 14% SO3, 3% CaO, 0,01% Bo, 0,02% Zn, dan 0,03% Mn. Aplikasi pupuk Fertila yang mengandung unsur hara lengkap dan kandungan kalium yang lebih tinggi merupakan salah satu alternatif untuk meningkatkan ukuran buah jeruk Terigas dan mutu buah yang lain serta hasil panen karena kalium merupakan unsur penting yang mempengaruhi ukuran buah (Ashkevari et al, 2013;Dalal et al, 2017;Koo, 2015;Obreza, 2003;Quaggio et al, 2011;Sutopo & Aji, 2020).…”

Pengujian pupuk Fertila (12-6-24 +2MgO+3CaO+14SO3+unsur mikro) bertujuan untuk mengetahui pengaruh dosis pupuk terhadap kadar N, P, K daun, kadar sari buah, kadar asam dan total padatan terlarut, serta efektivitas pupuk terhadap hasil buah jeruk keprok Terigas. Percobaan ini dilaksanakan di IP2TP Kliran dan Laboratorium Ekofisiologi, Balai Penelitian Tanaman Jeruk dan Buah Subtropika, pada Agustus 2017. Tanaman yang digunakan adalah keprok Terigas yang diokulasi pada batang bawah Japansche Citroen berusia 4 tahun, dengan produksi tahun sebelumnya adalah 20 kg/pohon. Percobaan disusun menggunakan rancangan acak kelompok dengan 6 perlakuan, yaitu kontrol (tanpa pupuk), pupuk rekomendasi (0,60 kg Urea (45% N) + 0,50 kg SP36 (36% P2O5) + 0,10 kg KCl (60% K2O)/pohon), serta pupuk Fertila dengan dosis 1,50, 2,25, 3,00, dan 3,75 kg/pohon. Setiap perlakuan diulang 4 kali. Hasil penelitian menunjukkan bahwa aplikasi pupuk Fertila pada Inceptisol dengan status N tanah rendah, P tersedia dan K dapat ditukar sedang, berpengaruh nyata terhadap kadar N dan K daun jeruk. Fertila pada dosis tertinggi menghasilkan sari buah dengan total padatan terlarut lebih besar dibandingkan dengan pupuk rekomendasi, tetapi tidak berbeda nyata pada kandungan sari buah dan total asam tertitrasi. Kecuali dosis 1,5 kg/pohon (7,5% dari bobot panen sebelumnya), pupuk Fertila menghasilkan efektivitas hasil buah lebih dari 100% dan dosis pupuk optimum yang dianjurkan adalah 3 kg/pohon setahun.
