Insights on the Nutritional Profiling of Cantaloupe (Cucumis melo L.) via 1-Naphthalene Acetic Acid.

The nutritional components of cantaloupe, including vitamins, minerals, antioxidants, and dietary fiber, contribute to overall health, improved immunity, hydration, and protection against chronic diseases. This study was conducted to investigate the influence of different concentrations (0 (control), 100, 150, and 200 ppm) of 1-naphthalene acetic acid (1-NAA) on the nutritional components of the cantaloupe (Cucumis melo L. Var. Super White Honey). All the studied treatments were applied twice at the 2nd and 4th leaf stages. The applied concentrations of 1-NAA significantly improved the sex expression and fruit yield attributes. Different nutritional components like proximate contents, minerals, vitamins, selected fatty acids, and amino acids were analyzed. The results showed that the maximum moisture content, proteins, carbohydrates, ash, and energy were recorded with 100 ppm. The higher lipids were recorded during the supplementation of 150 ppm. Significantly greater fibers were recorded using 200 ppm. Regarding minerals, 100 ppm was found to be the best as it increased calcium (Ca), magnesium (Mg), potassium (K), sodium (Na), phosphorous (P), manganese (Mn), copper (Cu), iron (Fe), and zinc (Zn). Vitamins were also found to be the maximum with 100 ppm, including vitamin A, vitamin B, vitamin C, vitamin D, vitamin E, and vitamin K. Total selected fatty acids and amino acids were also found significantly greater in the fruits administered 100 ppm.

Effect of Different Training System on Growth, Yield and Quality of Bottle Guard (Lagenaria siceraria L.) under Prayagraj Agro-Climatic Condition

The present investigation was planned to know the feasibility of training systems of growing vis-a-vis traditional method and their effects on growth, yield and quality traits in bottle gourd [Lagenaria siceraria (Mol.) Standl]. The results revealed that trailing method had significantly higher vine length (495.21 cm), number of nodes/vine (11.55) and chlorophyll content (40.32) at 90 DAS. The reduction in number of days to anthesis to first male flower (55.13 days) and female flower (62.30 days) in trailing as compared to other trailing systems. The fruit development attributes, viz. number of fruits plants-1 (9.47), fruit weight (4119.15 gm) were recorded significantly higher in trailing but significantly less fruit width (64.10m), were recorded in training system. Fruit yield attributes, i.e. the number of total fruit plant-1 (9.47), fruit yield plot-1 (9.84 kg), seed yield ha-1 (246.45 qha-1) was significantly higher in bower training system. The significant increase in germination (97.54%) was recorded in trailing system as compared to traditional system (95.21%). Similarly, seedling length (42.66 cm), and seedling dry weight (6.56 mg) were significantly higher in training systems. B:C ratio (4.60%) were also significantly superior in Inverted “V” trellis. The presence of fungi was lower in trailing than traditional among the infected fruits.

Performance of F1 Crosses of Brinjal (Solanum melongena L.) Landraces for Growth, Flowering and Fruit Yield Attributes

All total 21 F1 crosses of local landraces were evaluated along with seven parents and one check of brinjal by adopting RBD replicated twice at AICRP on Vegetable Crops, OUAT, Bhubaneswar, Odisha. The objective of the experiment was to evaluate the performance of F1 crosses for growth, flowering, fruit yield and yield attributes. Results revealed significant variations among various vegetative characters (plant height : 74.50 cm to 110.90 cm, plant spread (EW): 72.75 cm to 89.55 cm and NS :70.00 cm to 91.25cm, primary branches plant-1: 4.00 to 5.40), flowering parameters (days to 1st flowering:45.60 to 55.00 and 50% flowering: 55.00 to 66.40) and fruit yield attributes (fruit length:11.35 cm to 16.35 cm, fruit breadth :15.35 cm to 25.75 cm, fruit weight:118.40 g to 217.30g and fruits plant-1: 11.80 to 17.70). The F1 cross viz. BBSR-08-2 × Selection from BBSR-145-1(2.09 kg) recorded significantly highest fruit yield plant-1 followed by BBSR-08-2 × BBSR-10-25(1.98 kg) and BBSR-08-2 × BBSR-10-26 (1.91 kg). Thus, on the basis of per se performance, the F1 crosses viz. BBSR-08-2 × Selection from BBSR-145-1, BBSR-08-2 × BBSR-10-25 and BBSR-08-2 × BBSR-10-26 may be recommended for commercial cultivation. The parent Arka Neelanchal Shyama may be used as a parent to develop early variety in brinjal.

Phenotypic diversity for fruit quality traits and bioactive compounds in red-fleshed guava: Insights from multivariate analyses and machine learning algorithms

Precise characterization of genetic resources is critically important for developing high yielding and nutri-rich guava cultivars. This study aimed at delineating phenotypic diversity for fruit yield, quality and bioactive compounds in the newly developed red-fleshed guava selections and hybrids. Analysis of Variance (ANOVA) and the associated effect-size estimates revealed a high degree of phenotypic diversity for most of tree growth and fruit quality traits, minerals and bioactive compounds in the guava accessions analyzed. Principal Component Analysis efficiently discerned key trends in data with first and second Principal Components representing nutritional and bioactive compounds, and fruit yield attributes, respectively. Grouping of guava accessions into separate k-means clusters evinced a fairly high genetic divergence for the traits examined. Correlation and network analyses revealed that total antioxidant activity of fruits was strongly and positively regulated by total phenols (TP), β-carotene (β-car) and flavonoids (Flav). Gradient Boosting and Random Forest regression models also confirmed an overarching influence of TP, β-car and Flav in determining the total antioxidant activity. Our findings are expected to assist the guava breeders in selecting suitable parental combinations for future hybridization programs. The promising guava accessions identified by us meet the fresh consumption and processing standards, and may thus be considered for commercial planting.
