“…As reported earlier, changes in temperature and rainfall during critical stages resulted in a significant variation in crop yield and sugar recovery in three provinces of Pakistan, ultimately affecting overall production [47]. Jaiswal et al [48] described that K application to sugarcane resulted in a 19% increase in overall plant growth compared with soil without K fertilization. Thus, adequate K supply to sugarcane reduces moisture stress, induces salt tolerance to sugarcane [16,21], and produces higher stalk and cane yields [47,48].…”

The imbalanced use of fertilizers and irrigation water, particularly supplied from groundwater, has adversely affected crop yield and harvest quality in sugarcane (Saccharum officinarum L.). In this experiment, we evaluated the impact of potassium (K) and micronutrients [viz. Zinc (Zn), Iron (Fe), and Boron (B)] application and irrigation water from two sources, viz. canal, and tube well water on sugarcane growth, yield, and cane quality under field trails. Water samples from Mardan (canal water) and Rahim Yar Khan (tube well water) were analyzed for chemical and nutritional attributes. The results revealed that tube well water’s electrical conductivity (EC) was three-fold that of canal water. Based on the EC and total dissolved salts (TDS), 83.33% of the samples were suitable for irrigation, while the sodium adsorption ratio (SAR) indicated only a 4.76% fit and a 35.71% marginal fit compared with canal water. Furthermore, the application of K along with B, Fe, and Zn had led to a significant increase in cane height (12.8%, 9.8%, and 10.6%), cane girth (15.8%, 15.6%, and 11.6%), cane yield (13.7%, 12.3%, and 11.5%), brix contents (14%, 12.2%, and 13%), polarity (15.4%, 1.4%, and 14%), and sugar recovery (7.3%, 5.9%, and 6%) in the tube well irrigation system. For the canal water system, B, Fe, and Zn increased cane height by 15.3%, 13.42%, and 11.6%, cane girth by 13.9%, 9.9%, and 6.5%, cane yield by 42.9%, 43.5%, and 42%, brix content by 10.9%, 7.7%, and 8%, polarity by 33.4%, 28%, and 30%, and sugar recovery by 4.0%, 3.9%, and 2.0%, respectively, compared with sole NPK application. In conclusion, the utilization of tube well water in combination with canal water has shown better results in terms of yield and quality compared with the sole application of canal water. In addition, the combined application of K and B significantly improved sugarcane yields compared with Zn and Fe, even with marginally suitable irrigation water.

“…Among the varieties, RB992506 produced 35% more dry matter than RB92579 (Figure 3B). Several studies observed an increase in sugarcane yield due to the higher amount of K + , in both the field and a greenhouse, as well as different yield increases in the varieties with the same amount of K + applied (UCHÔA et al, 2009;CAVALCANTE et al, 2015;JAISWAL et al, 2021).…”

Biochemical differences in the initial growth of sugarcane varieties cultivated under different potassium doses and water conditions

et al. 2023

Sugarcane varieties have distinct biochemical and productive capacities, which are accentuated under water and nutrient stress conditions. Water stress promotes biochemical changes in plants, such as the overproduction of reactive oxygen species (ROS) that, depending on the concentration, degrade photosynthetic pigments. Current research indicates that K+ plays an important role in increasing yield and tolerance to water stress. This study evaluated the effect of different K+ levels on the initial growth of two sugarcane varieties under two water conditions. The experiment was conducted in a greenhouse using randomized blocks, with four replications, five K+ doses (0; 0.5; 1; 2 and 6 mmol L-1), two sugarcane varieties (RB92579 and RB992506), and two water conditions (hydrated plants and water stress). Data were analyzed in a 5×2×2 factorial scheme. Leaf carbohydrates, photosynthetic pigments, antioxidant enzyme activity (catalase, superoxide dismutase and ascorbate peroxidase) and dry matter production were assessed. K+ doses promoted an increase in plant dry mass. The RB992506 variety had lower APX activity and higher levels of photosynthetic pigments, carbohydrates and dry matter than its RB92579 counterpart. Water conditions and interactions between factors had no effect on the variables studied. RB992506 is a promising variety and more tolerant to water stress due to its superior biochemical and productive traits when compared to RB92579.

Effect of various pre-harvest treatments on shelf life and morphological characteristics of fruits of mango (Mangifera indica L.) var. ‘Amrapali’

The mango is considered as ‘king of fruits’ in India due to its delicious taste and nutritional status. Extension of fruit shelf life is a prime importance for availability of fresh fruit in market for longer duration and distance transportation. India is the largest producer and a prominent exporter of mango in the world.In this context, the study was conducted to evaluate the effect of preharvest spray of different chemicals and plant growth regulators (PGRs) on mango var. ‘Amrapali’ for shelf life and its quality. As ‘Amrapali’ has regular bearer with very good flavor and taste with a late maturing character, selected for shelf life studies. The fruits of mango weresprayed with chemicals viz. CaCl2 1%, CaCl2 2%, Ca(NO3)2 1%, Ca(NO3)2 2%, KNO3 1%, KNO3 2%, GA3 25 mg/l, GA3 50 mg/l, Ethrel 0.1 ml/l and Ethrel 0.2 ml/l prior to harvest. After harvesting, fruits were stored under ambient storage condition. Among all the treatments, GA3 25 mg/l treatment recorded significantly highest fruit length, fruit diameter, fruit volume and fruit weight at harvest and at fully ripe stage. Application of CaCl22% resulted in significantly minimum physiological loss in weight consistently from 2nd day to 16th day of storage besides significantly highest shelf life and quality. Hence, this intervention can contribute in preserving physical and chemical quality attributes for maximum acceptance by consumers.
