Wastewater irrigation for vegetable cultivation is greatly concerned about the presence of toxic metals in irrigated soil and vegetables which causes possible threats to human health. This study aimed to ascertain the accumulation of heavy metals (HMs) in edible parts of vegetables irrigated with different stages of textile dyeing wastewater (TDW). Bio-concentration factor (BCF), Estimated daily intake (EDI), and target hazard quotient (THQ) were computed to estimate human health risks and specu

Reuse of wastewater for vegetable cultivation is becoming popular in order to augment the inadequate irrigation supplies and meet the growing demands of ground water for agriculture and industries production in different regions of the world. This study was investigated to optimize different stages of textile dyeing wastewater (TDW) for irrigation focusing on their effect on growth, yield and physiochemical attributes of tomato, plant nutrient use, heavy metals enrichment and pollution load of t

Carrot is a seasonal perishable tuberous root vegetable which presents a preservation challenge owing to its elevated moisture content. Recently, carrot processing has received more attention because of its many health-promoting qualities and the reduction of postharvest losses in a cost-effective safe way. This study was designed to sort out the effective solar drying technique including pre-treatment that would retain the color and quality characteristics of dehydrated carrot. Carrot slices we

Pointed gourd (<i>Trichosanthes dioica</i> Roxb.) (2n = 2x = 22) is a dioecious cucurbit vegetable and green fruit that is edible after cooking. Consumers prefer to consume seedless or less-seeded fruit because seeds are unpalatable due to their hard coats. Therefore, the cross compatibility between the diploid and induced tetraploid will be helpful for seedless or less-seeded fruit production. Thus, the present study was conducted using mature seeds that were immersed in 0.05%, 0.1%, and 0.5% c

The efficiency of modified atmosphere packaging (MAP) in combination with postharvest treatment on the shelf-life, physiochemical attributes, color, and nutrition of pointed gourd was studied after storing in refrigerated (low temperature, LT) and ambient (room temperature, RT) conditions. Fresh pointed gourd fruits were dipped in NaOCl solution (0.01% w/v) and potassium metabisulphite (KMS) (0.05% w/v), blanched (100°C for 4 min), and then packed in perforated and non-perforated polythene and p

Horticultural crops are highly nutritious and shared lion portion of our daily diet. These items are consumed in different ways according to their nature and processing processes. These days, a crucial concerning issue is arising globally to ensure nutrition security for huge population that leads to focus on production increase, quality improvement, food safety assurance, and processing strategies. Consequently, a large amount of waste generates in the processing industries, household kitchen,

The country bean (<i>Lablab purpureus</i>), is a significant contributor of dietary protein and other essential components in human nutrition. Because of its elevated moisture content, it is susceptible to rapid decay, leading to losses after harvesting. The utilization of solar drying has attracted significant attention as a tactic to minimize nutrient depletion in dried goods and enhance their longevity. This study employed four solar drying techniques, namely long chimney, short chimney, box

Pointed gourd ( Trichosanthes dioica Roxb.) is a dioecious, cucurbit summer vegetable, and green fruit is the main edible part at 15-18 days after pollination. However, consumer preference goes to fruit without seed since seeds are unpalatable to have after cooking due to their hard seed coat. To overcome this problem by parthenocarpy induction, six types of plant growth regulators [2,4-dichlorophenoxyacetic acid (2,4-D); naphthaleneacetic acid (NAA); N-(2-chloro-4 pyridyl)-N-phenylurea (CPPU);

An experiment has been completed on the impact of dying effluents on germination and seedlings of country beans (Lablab niger var. typicus Medikus, Fabaceae). Seven types of dyeing effluents have been taken as treatment variables, and their effects on the germination of country beans at the early growth stage compared The treatment of neutralized effluent water (D5) enhanced the germination percentage remarkably (100%) as well as statistically identical with the result of underground water (D1)

Pointed gourd (Trichosanthes dioica Roxb.) is a dioecious, fruit type cucurbit vegetable originated in India and Bangladesh. Immature fruits at green stage are commonly consumed as a vegetable after cooking. It is extensively cultivated during summer season in tropical and subtropical regions but potential to grow in temperate regions due to its wide range of phenotypic and genotypic variability. The exploitation of these variations might be the basis for subsequent improvement of this crop. The

Tomato is known for its remarkable contents of vitamins, minerals and antioxidants. A pot experiment was performed during the winter-summer transition from December 2022 to April 2023 combining low to high fertilizer rates and plant growth regulators (PGRs). The objective was to decrease the utilization of artificial fertilizers through the application of PGRs. Besides recommended dose (12 g of urea, 10 g of TSP, 5 g of MoP, 3 g of Gypsum, 0.5 g of ZnSO₄, and 0.5 g of Boric acid per p

This study aimed to reveal the effect of silver nitrate on sex modification in dioecious pointed gourd (Trichosanthes dioica Roxb.) originated in South Asia, and to explore the possibility of crossing among female plants. Three concentrations (50, 100, and 200 ppm) of silver nitrate were applied as foliar spray on female vines of three pointed gourd accessions. Application of 50 ppm silver nitrate found as effect to induce maximum proportion of hermaphrodite flowers with expanded duration irresp

Pointed gourd (Trichosanthes dioica Roxb.) is a dioecious cucurbit vegetable and fruit is the main edible part. In this experiment, we elucidated the flowering time temperature variations effect on the flowering habit, fruit yield and pollen germination ability under glasshouse and open field conditions. The highest number of female flowers (32.3), harvested fruits (29.6) and fruit weight (53.3 g) were found in 16–30 June with average day/night temperature 27.1/23.9˚C in the glasshouse cultivati

This study evaluated the exogenous application of PGRs substitute chemical fertilization without compromising the growth and yield of tomato in fluctuated day-night temperature and humidity stressed late winter. Two-factor experiment comprising chemical fertilizers at 100, 110, 90 and 80 % of recommended doses besides control and PGRs of GA3; NAA, 4-CPA and SA @ 50 ppm including control was conducted where treatments were assigned in triplicates. Results revealed no significant variation among t
