“…Furthermore, the yields of the SV and SVM treatments were no higher than the yields of other treatments. Several studies have shown that soil potassium analyses are not well correlated with sugarcane yields [19,31,32]. In very clayey soils, such as the Nitisol in our study, potassium inputs above 225 kg•ha −1 did not increase yields [32].…”

Sugarcane cultivation is suitable for the exploitation of organic waste products. However, minimum complementary mineral input is necessary for optimal fertilisation. Control mineral fertilisation treatments with mulch (MCM) or without mulch (MC) were compared with two organic waste treatments, a pig slurry with mulch (PSM) and without mulch (PS), and a sugarcane vinasse with mulch (SVM) and without mulch (SV) on a Nitisol in French Reunion Island. The sugarcane yields obtained with the different treatments differed each year. However, no trend was observed and no significant and recurrent effect of the presence of mulch or of the different treatments was identified over the course of the 4 year experiment. Soil pHw and pH KCl measured in the different treatments increased from year 3 in with the treatments including organic waste products (PS, PSM, SV and SVM) but remained constant with the treatments including only mineral fertilisation (MC and MCM). With the exception of PS and PSM, which were significantly higher in year 4, soil organic carbon content was not modified by the treatments. Soil cation exchange capacity increased only slightly with the PS and PSM treatments from year 3 on. The differences in yields and soil properties can be explained by the nature of the organic waste products, the accumulation of nutrients after several applications, and the specific characteristics of the sugarcane crop. The improvement in soil properties from the third year on was not reflected in the yield of sugarcane because it was too weak, and the crop explores a much larger volume of soil.

“…Consequently, K is a crucial element in achieving sustainable ratoon sugarcane production [64], as it activates photosynthesis, protein synthesis, starch production, and protein and sugar translocation [46,65]. The transfer of photosynthates in sugarcane is significantly reduced when K is in deficit [22,27,62]. Sugarcane crops react significantly to K fertilization only in soils with low available K [30].…”

“…Additionally, K aids in the functioning of plant enzymes, acting as a catalyst for the activation of around 60 [19][20][21]. K is also involved in seed germination, transport of photosynthate from leaves to rest plant [22][23][24][25][26], maintaining a balance of cations and anions within plant parts, protein synthesis, photosynthesis, energy transfer [16,27,28], and stress resistance [8,17,18]. K also interacts with other plant nutrients such as N to enhance their use efficiencies and reduce overall cultivation costs of sugarcane cultivation [28][29][30][31][32].…”

Potassium and Water-Deficient Conditions Influence the Growth, Yield and Quality of Ratoon Sugarcane (Saccharum officinarum L.) in a Semi-Arid Agroecosystem

Groundwater and soil potassium deficiencies are present in northern India. Sugarcane is a vital crop in the Indian Punjab; it is grown on approximately 91,000 hectares with an average yield of 80 tonnes ha−1 and a sugar recovery rate of 9.59%. The role of potassium (K) fertilizer under both sufficient and deficient irrigation in ratoon sugarcane crops is not well documented. We conducted a split-plot ratoon cane experiment during 2020–2021 at the Gurdaspur Regional Research Station of Punjab Agricultural University, India, on K-deficient soils. Main treatments were fully irrigated (I1) and water stressed (I0) conditions, with sub-treatments reflecting K fertilizer application rates of 0 (M1), 67 (M2), 133 (M3), and 200 (M4) kg K ha−1. The ratoon sugarcane performance was assessed in terms of growth, productivity, sugar quality and incidence of key insect pests. At harvest, trends in the growth and yield parameters in I1 were improved over the I0 treatment, with cane height (+12.2%), diameter (+3.3%), number of internodes (+5.4%), biomass yield (+7.6%) and cane yield (+5.9%) all higher, although little significant difference was observed between treatments. Ratoon cane yield under irrigation was 57.1 tonnes ha−1; in water-stressed conditions, it was 54.7 tonnes ha−1. In terms of sugarcane quality parameters, measured 12 months after harvesting the initial seed crop, values of Brix (+3.6%), pol (+3.9%), commercial cane sugar percentage (+4.0%) and extractable sugar percentage (+2.8%) were all higher in the irrigated treatments than the water-stressed plot. Irrigated treatments also had a significantly lower incidence of two key insect pests: top borer (Scirpophaga excerptalis) was reduced by 18.5% and stalk borer (Chilo auricilius) by 21.7%. The M3 and M4 treatments resulted in the highest cane yield and lowest incidence of insect pests compared to other K-fertilizer treatments. Economic return on K-fertilizer application increased with increasing fertilizer dosage. Under the potassium-deficient water-stressed conditions of the region of north India, a fertilizer application rate of 133 kg K ha−1 is recommended to improve ratoon sugarcane growth, yield, and quality parameters and economic returns for sugarcane farmers.

“…Therefore, cane need based K fertilization is a must for attaining the improved growth, yield and quality parameters as depicted in Table 12 ( Chatterjee et al 1998). Under the deficit moisture conditions, K-uptake from the soil solution decreased which further reduces the net transpiration rates and cane yields (Filho 1985;Sudama et al 1998;Ghaffar et al 2013;Bhatt et al 2020). Some workers reported no significant changes in yield parameters on applying potash (Lakholive et al 1979;Olalla et al 1986;Ghaffar et al 2013;Bhatt et al 2020), while some reported a significant increase in cane quality as well as growth and yields (Korndorfer 1990;Prasad et al 1996;Nagarajah 2006).…”

Sugarcane is an important cash crop cultivated globally from temperate to tropical regions. Improving cane yield and recovery sustainably is an important research area for improving livelihoods of the cane farmers. Among different approaches sill judicious and integrated use of nutrients as per plant needs holds the special place. Further, applying need based N management through optical gadgets viz. Leaf color chart (LCC), SPAD, Green seeker, integrated nutrient management, fertigation, special focus on for improving the efficiency of different fertilizers through different state of art technologies. For having higher fertilizer use efficiency in sugarcane, some aspects of fertilization especially How much? What type of? When to add? Is it worth? Number of splits? Mode of action? must be considered both for seed or ratoon. Further, soil textural class and climatic conditions on one side while on changing climatic conditions also affected it a lot. Further, inherent fertility status of the soils is also an important factor which affects the fate of applied fertilizers. There is a need to create awareness in between the farmers for not to applying huge quantity of different fertilizers as per their neighboring farmers, rather farmer should be smart enough to adopt different technologies in a smart way for having better benefits and thus livelihoods as the purpose is to fed the canes but not the soil. In the present review an attempt being made to compare the comparative performance of sugarcane with respect to fertilization for finally guiding the sugarcane cultivars. Idea is to enlighten them regarding need based sustainable fertilization with an aim to improve the fertilizer use efficiencies for having improved yield and quality parameters instead of loading the soil with much of fertilizers which further have environmental concerns.
