“…Like known inorganic sources, the K in these organic compounds is primarily available for plant absorption. Repeated applications of significant amounts of manure can cause K accumulation in the soil, contributing to the plant's excessive K consumption (Mikkelsen, 2007;Turaev et al, 2023).…”

Potassium (K) is a crucial element required for the healthy growth of plants, as it activates many enzymatic reactions in the plant body. Nowadays, K-deficiency is widespread worldwide. The high cost of potassium fertilization and less awareness about the pros of external nutrition from K fertilizer application are possible reasons for K-deficient soils in Pakistan. Efforts are ongoing to improve the potassium use efficiency (KUE) and bioavailability of K from commercial potassium sources. Therefore, a field experiment commenced to minimize the bioavailable K losses using carbon sequestering fertilizer (CSF) under saline soil conditions (4 dS m -1 ) using wheat as a test crop in Pind Dadan Khan, Punjab, Pakistan. The experiment ran in a three-replication randomized complete block design (RCBD) statistical scheme using four treatments, i.e., T1 = Control; T2 = Filter cake press mud (FCP) as CSF; T3 = Sulphate of potash (SOP); and T4 = SOP + FCP, using two wheat varieties, namely, Faisalabad 2008 (FSD-08) and Chakwal-50. Results implied that SOP application in combination with FCP (T4) performed best treatments with Faisalabad 2008 as the better variety than Chakwal-50 under saline growth environment. Maximum spike length (8.85 cm), the number of grains/spike (45), shoot dry weight (2.75 g), soil K contents (310 ppm), soil C content (1.03%), chlorophyll content (2.18 µmol m -2 ), and H-ATPs (99.5) resulted in Faisalabad 2008 when applied with the combination of SOP and FCP (T4). Thus, the combined application of mineral and organic sources of CSF improved the wheat growth parameters and nutritional status of the soil.

Cotton (Gossypium spp.) is the most important natural fiber source in the world. The genetic potential of cotton can be successfully and efficiently exploited by identifying and solving the complex fundamental problems of systematics, evolution, and phylogeny, based on interspecific hybridization of cotton. This study describes the results of interspecific hybridization of G. herbaceum L. (A1-genome) and G. mustelinum Miers ex Watt (AD4-genome) species, obtaining fertile hybrids through synthetic polyploidization of otherwise sterile triploid forms with colchicine (C22H25NO6) treatment. The fertile F1C hybrids were produced from five different cross combinations: (1) G. herbaceum subsp. frutescens × G. mustelinum; (2) G. herbaceum subsp. pseudoarboreum × G. mustelinum; (3) G. herbaceum subsp. pseudoarboreum f. harga × G. mustelinum; (4) G. herbaceum subsp. africanum × G. mustelinum; (5) G. herbaceum subsp. euherbaceum (variety A-833) × G. mustelinum. Cytogenetic analysis discovered normal conjugation of bivalent chromosomes in addition to univalent, open, and closed ring-shaped quadrivalent chromosomes at the stage of metaphase I in the F1C and F2C hybrids. The setting of hybrid bolls obtained as a result of these crosses ranged from 13.8–92.2%, the fertility of seeds in hybrid bolls from 9.7–16.3%, and the pollen viability rates from 36.6–63.8%. Two transgressive plants with long fiber of 35.1–37.0 mm and one plant with extra-long fiber of 39.1–41.0 mm were identified in the F2C progeny of G. herbaceum subsp. frutescens × G. mustelinum cross. Phylogenetic analysis with 72 SSR markers that detect genomic changes showed that tetraploid hybrids derived from the G. herbaceum × G. mustelinum were closer to the species G. mustelinum. The G. herbaceum subsp. frutescens was closer to the cultivated form, and its subsp. africanum was closer to the wild form. New knowledge of the interspecific hybridization and synthetic polyploidization was developed for understanding the genetic mechanisms of the evolution of tetraploid cotton during speciation. The synthetic polyploids of cotton obtained in this study would provide beneficial genes for developing new cotton varieties of the G. hirsutum species, with high-quality cotton fiber and strong tolerance to biotic or abiotic stress. In particular, the introduction of these polyploids to conventional and molecular breeding can serve as a bridge of transferring valuable genes related to high-quality fiber and stress tolerance from different cotton species to the new cultivars.
