“…Over the last decade, the design of advanced polymeric structured materials has gained massive attention in the development of sustainable agriculture. [36][37][38][39] Mittal et al 40 highlight the importance of innovative technologies, such as polymerbased nanoformulations, as alternatives to enhance nutrient use efficiency physiological processes, such as germination, hence boosting productivity and food security in the future. In this sense, amine-epoxide nanogels have never been explored for agricultural purposes.…”

“…The uptake of K changes significantly depending on the stage of growth of sunflower, for instance, at the seedling stage, sunflower has weak roots and poor nutrient uptake ability, so an adequate supply of nutrients is essential at this stage of growth (Li et al, 2014). Plants have difficulty absorbing K from calcareous soils due to soil texture, high CaCO 3 , alkaline pH, nutrient interaction, and nutritional imbalances (Wakeel et al, 2017;Taalab et al, 2019;Narayanasamy et al, 2023). Around 20 million hectares of agricultural soils in Pakistan are calcareous and 1/4 th of the Indus plains (Recent, sub-recent, flood plains, estuaries, delta, creeks etc.)…”

“…Calcareous soils present several challenges for K availability and plant uptake due to several issues, including: High levels of CaCO 3 , high pH, high EC levels, antagonistic relationship of K with Na, Ca and Mg, low microbial activity (Sahai, 2004;Taalab et al, 2019;Babar et al, 2022;Wang et al, 2023), fixation by clay minerals, Low cation exchange capacity, presence of carbonates, lack of organic matter, soil texture and the precipitation of K (Ertiftik and Zengin, 2015;Wakeel et al, 2017;Narayanasamy et al, 2023). The increase in soil exchangeable Ca and Mg during the prolonged period is responsible for the decrease in leaf tissue K content and its subsequent uptake (Xie et al, 2020).…”

S unflower is a non-traditional and profit-oriented oil seed crop with the potential to bridge the gap between edible oil imports and domestic production in Pakistan (Hameed and Azeem, 2017;Rana et al., 2022). However, the average sunflower yields in the country during 2021 was 1377 kg ha -1 (GOP, 2021) are far below potential yield 3073-3083 kg ha -1 which has been recorded by research centres and Abstract | Soils of Sindh are highly calcareous, consequently limiting potassium (K) supply to crops including sunflower due to low K activity ratio. The research was conducted to ascertain whether K foliar applications can improve growth, and yield of sunflower in calcareous soil. The sunflower cultivar (HO-1) was tested in field with three foliar K sources (Kfs) (MoP, SoP and NoP) and three foliar K times (Kft) treatments (2% once at leaf development stage (LDS), 2% in two equal splits (1% at LDS and 1% inflorescence emergence stage (IES), and 2% in three equal splits (0.67% at LDS, 0.67% IES and 0.67% flower bud development stage (FS). Three repeats of treatments arranged in randomized complete block design. The Kfs affected growth related parameters, chlorophyll concentration, leaf K concentration, seed yields significantly. Application of NoP and SoP raised the seed yield by 9.09% and 8.66% , respectively, over control. Oil content increased by 15% with NoP and 13% with SoP, over control, respectively. The significant Kft variations were also observed for most of the variables studied for field-grown sunflower plants. Among interaction of Kfs x Kft, seed and oil yields were obtained to be highest in T3 when NoP>SoP>MoP were sprayed with 0.67% spray each at LDS, IES and FS stage. It can be concluded that under the calcareous conditions of Sindh, foliar application of 2% K (2 or 3 equal splits at LDS, IES and FS) through NoP, SoP, and MoP sources increase the growth, seed and oil content of sunflower.

The fixation of K and variation in basic cation ratios limit the concentration of K in the soil solution for plant uptake (Wakeel et al, 2017).…”

“…Besides several other issues (high pH, low N, P and organic matter), the problem of K availability and uptake by plants in calcareous soils has extensively been noticed and reported in the world mainly due to antagonistic relationship with other basic cations i.e., Na + , Ca 2+ and Mg 2+ present in such soils (Ertiftik and Zengin, 2015;Narayanasamy et al, 2023). The majority of the K in plant tissue is absorbed by roots from the soil solution as a monovalent cation, and the rate of absorption is controlled by environmental and plant factors ( Jan and Hussan, 2022).…”

C alcareous soils are soils that contain calcium carbonate (CaCO 3 ) in one or more on their horizons, with concentrations ranging from a few to 95% (Weil and Brady, 2017). High amount of CaCO 3 affect the physicochemical characteristics of soil, reducing crop productivity due to high soil pH, Abstract | The arid and semi-arid climate and geology of Pakistan have caused the formation of calcareous soils on many regions. High calcium amount in soil solution suppresses potassium (K) uptake by plants possibly due to K-fixation and variation in cation ratios. Soils in country are thought to be well supplied with K, little or no K fertilizer is applied to majority of the crops, including sunflower. However, recent studies have shown that the sunflower is becoming more responsive and exhibiting superior growth and yield with the addition of K. To determine the impact of K fertilizer sources on the growth and development of sunflower seedlings on artificially established calcareous soils, we carried out a pot study. The experiment included two K sources, sulphate of potash (SoP), and muriate of potash (MoP), and four different lime content levels (<5, 10, 20 and 30%). The results showed that increasing levels of lime decreased growth parameters viz. shoot height, root length, fresh shoot weight, dry shoot weight, fresh root weight, and dry root weight in sunflower seedlings. Similarly, shoot K content was also decreased by 30.44% at increased lime content level (30%) over control, and chlorophyll concentration in leaves declined with increasing% of lime in comparison with the control. Moreover, when compared to the control, SoP application resulted in greater growth parameters, followed by MoP. Further K treatment also increased in K content in shoots and leaf chlorophyll concentration. The shoot K content was increased by 31.14% with SoP and 13.92% with MoP, and chlorophyll concentration by 24.52% with SoP, and 12.06% with MoP compared with the control. The findings concluded that under calcareous soil conditions, K fertilization either in the form of SoP or MoP could more effectively promote sunflower seedling growth.
