Effects of vermicompost as an alternative substrate on yield and quality of cauliflower and pepper seedlings

It is wondered whether vermicompost can be an alternative to peat in seedling production. Therefore, this study investigated the effects of different vermicompost rates on the growth, quality characteristics and macro and micro mineral concentrations of pepper and cauliflower seedlings. There were 4 treatments consisting of different mixtures in the study. T1: 70% peat + 27% perlite + 3% vermiculite; T2: 70% vermicompost + 27% perlite + 3% vermiculite; T3: 35% peat + 35% vermicompost + 27% perlite + 3% vermiculite; T4: 100% vermicompost. ‘Sivrillo’ F1 (Capsicum annuum var. longum) pepper and ‘Casper’ F1 (Brassica oleraceae var. botrytis) cauliflower varieties were used as the plant material. Vermicompost mixtures had a significant impact on pepper and cauliflower seedlings. The emergence and growth characteristics of pepper seedlings were similar in T1, T2 and T3 treatments. However, the T3 mixture provided the highest emergence rate and seedling height in cauliflower seedlings. T3 also increased the leaf area both pepper and cauliflower seedlings more than the other treatments. Although T2 medium showed the highest N, K, and Mg contents in pepper seedlings, vermicompost mixtures had the highest P, K, Ca, and Mg concentrations in cauliflower. Vermicompost mixtures had higher microelement contents in cauliflower, whereas similar results were obtained from T2 and T1 treatments in pepper seedlings. In conclusion, it was determined that the 35% peat and 35% vermicompost mixture was appropriate for pepper and cauliflower seedlings in terms of many criteria. Additionally, noteworthy results were obtained when 70% peat was substituted with vermicompost.

Preservation of Postharvest Quality of Fresh-Cut Cauliflower through Exogenous Putrescine, Citric Acid and Salicylic Acid Treatments

Cauliflower is among the perishable vegetables after harvest. In recent years, the popularity of fresh-cut cauliflower has increased among consumers as a minimally processed product. This study was carried out to determine the effects of exogenous putrescine (PUT), citric acid (CA) and salicylic acid (SA) treatments on postharvest quality of fresh-cut cauliflower stored at 4±0.5 °C and 90±5% relative humidity for 21 days. In the study, a total of seven different treatments using two different doses (0.5 and 1.0 mM) of PUT, CA and SA were investigated. To evaluate the quality of fresh-cut cauliflower, the necessary measurements and analyzes were performed at periodic intervals on days 0, 7, 14, and 21 of storage. The results demonstrated that quality properties changed significantly depending on the postharvest treatments and storage durations. With the increase of storage duration, weight loss and ash content increased, while K, Zn and Cu contents decreased. In general, the treatments examined in the study had positive effects on postharvest quality of cauliflower. Among the treatments, especially 1.0 mM PUT was found to be more effective. Compared to the control, 1.0 mM PUT treatment decreased weight loss by 61.32%, though it increased protein content by 14.48% and P content by 21.55%. It was concluded that 1.0 mM PUT treatment can be recommended as an alternative application method to extend the storage life of fresh-cut cauliflower and reduce postharvest quality losses.

Application of Fe2O3-nano fertilizer (Fe2O3-N) along the Azotobacter, FYM, and PSB was shown encouraging growth effects to improve the cropping behavior. Fe2O3 NPs positively enhance the photosynthetic activity and stimulate catalyze enzymatic action in plant leaves that effect the health of the plant and remarkably increase the crop yield.

MODIFIED ATMOSPHERE PACKAGING OF CAULIFLOWER FOR ENHANCING THE EFFECTIVENESS OF COOL BOT COLD STORAGE TO PRESERVE THE POSTHARVEST QUALITY IN NEPAL

In recent years, cool bot storage was introduced to smallholder farmers in Nepal as a low-cost alternative to cold storage. The present study was carried out to evaluate the efficacy of different poly films in perforated modified atmosphere packaging on the postharvest life of cauliflower in cool bot-equipped cold rooms and ambient room conditions in the years 2019 and 2020 in the month of December. The cauliflower curds (hybrid variety White Top) were harvested from commercial vegetable growers at a fully mature stage. The compact and mature curds were harvested in the morning and brought to the National Horticulture Research Centre in Khumaltar. The curds were kept overnight for pre-cooling. Four different poly films (25 μ, 50 μ, 75 μ, and 100 low-density polyethylene with 16 perforations were used during storage in two different storage conditions. The study was conducted in a completely randomized block design. Curds were kept at ambient room conditions (15.5°C, 58% RH) for 10 days and at cool, bot devised, cold storage (11.25°C, 96% RH) for 15 days and analyzed for various postharvest quality parameters every 5 days of storage. The results modified atmosphere packaging i.e.50μ LDPE was found effective in cauliflower stored in ambient room conditions with quality perspective but the packaging didn’t provide additive effects in shelf life and quality of cauliflower in cool bot storage conditions.

Response of Cauliflower (Brassica oleracea var. Botrytis) to Micronutrient Mixture in the Micronutrient Deficient Alfisol

Aim: Though the effect of foliar application of micronutrients is well established, research on the performance of cauliflower with combined application of micronutrients is very meager. Keeping this in view, the research work was proposed to assess the effect of Micronutrient Mixture on the growth, yield, and quality of cauliflower under field conditions.
 Study Design: The field experiment in a randomized block design consisted of 6 treatment combinations with four replications.
 Place and Duration of Study: The experiment was conducted at Farmers Field, Deverayapuram, Thondamuthur, Coimbatore. The field experiment was conducted from March 2023 to May 2023.
 Methodology: The micronutrient mixture specific to cauliflower was developed at various levels based on their requirement to crop, with data obtained from soil testing, literature on nutrient uptake, and micronutrient deficiencies in cauliflower crops. Different rates of micronutrient mixture viz., 15, 20, 25, and 30 kg ha-1 combined with farmyard manure (FYM), were used to enhance fertilizer solubility.
 Results: It was recorded that the application of Micronutrient Mixture @ 30 kg ha-1 increased morphological characters and yield compared to other treatments followed by the Micronutrient Mixture @ 25 kg ha-1. The minimum yield and morphological characters were recorded in the control plot where neither FYM nor Micronutrient Mixture was applied.
 Conclusion: This research depicted that the combined application of a micronutrient mixture @ 30 kg ha-1 incubated with FYM has a positive impact on the growth, yield, and quality of cauliflower in micronutrient-deficient soil under field conditions resulting in improved morphological characters and crop yield. Hence, it may be concluded that an optimum dose of 30kg ha-1 can be recommended for cauliflower in micronutrient-deficient soils to enhance crop productivity.

Physicochemical quality of cauliflower as influenced by cling film wrapping during storage

Compact, medium size, white to creamy cauliflower curds were packed into different packaging techniques like i. without packaging (control); ii. packed in low density polyethylene (LDPE) bag with 1% perforation; iii. wrapped with polyethylene (PE) cling film and iv. newspaper (locally used). Half of each treatment was kept at (6±1°C and 50±5% RH) and the other half was kept at ambient conditions (25±3°C and 60±5% RH). LDPE bag or PE cling film has a great effect to retain firmness and reduce weight loss of cauliflower in both storage conditions. Respiration rate, rot incidence and changes of colour values (lightness and hue angle) was reduced significantly for the cauliflowers packed in LDPE bag or wrapped with PE cling film stored in a refrigerator than that of control (without packaging) and all packaging techniques stored at ambient condition throughout the storage period. Initially, acidity, TSS and ascorbic acid content were 0.26%, 4.7° Brix and 58.7 mg 100g-1, respectively. Ascorbic acid content was reduced severely in the cauliflower stored in ambient conditions than that stored in a refrigerator. Cauliflower wrapped with PE cling film and packed in an LDPE bag (1% perforation) stored in a refrigerator (6±1°C and 50±5% RH) could retain white colour, good sensory quality, firm and fresh curds with minimum loss in weight, texture and disease incidence up to 18 days and 16 days, respectively.

NPK3+PGPR+ OCMResults: The highest curd weight and marketable yield were observed in NPK2+ OCM in 2014 while in NPK1+PGPR+OCM and NPK2+PGPR+OCM in 2015. NPK2+ OCM elevated the curd weight and marketable yield by 300% compared to the control in 2014. NPK1+PGPR+OCM increased the curd weight and marketable yield by 200% compared to the control in 2015. The highest TSS was observed in the control in 2014 whereas NPK1+PGPR+OCM gave the highest value. NPK treatments elevated the NO3 content of cauliflower curds. In 2014 the highest ascorbic acid content was determined in PGPR while the control gave the highest content in 2015. The highest oxalic acid contents were observed in NPK treatments. Furthermore, PGPR and OCM treatments generally reduced the oxalic acid contents of the cauliflower. Conclusion: NPK with OCM and PGPR applications could be advisable for the yield and quality parameters of cauliflower. Furthermore, the PGPRxOCM combination was advisable for efficiently using in organic agricultural production.

Impact of High-Pressure Processing (HPP) on Selected Quality and Nutritional Parameters of Cauliflower (Brassica oleracea var. Botrytis)

In recent years, innovative food processing methods, such as high-pressure processing (HPP) treatment, have been shown to improve food quality. The purpose of this work was to determine the effects of high-pressure processing (HPP; 400 and 600 MPa for 2 or 5 min, 20 °C) of cauliflower. Microbial shelf-life (total aerobic count and spores), texture, color, drip loss, dry matter, antioxidative capacity, total phenolic content, and ascorbic acid were analyzed before and after processing, as well as during storage (4 °C) for up to 42 days. Among the different treatments, HPP at 600 MPa exhibited low microbial counts between days 14 and 28 of storage, while at 400 MPa already had high bacterial counts between days 7 and 14. HPP at both 400 and 600 MPa was the best method to maintain the color during storage. The texture of the cauliflower did not differ from the control during storage for HPP. For all samples, the dry matter content remained stable during storage, with few differences between treatments. The nutritional quality of high-pressure-processed cauliflower at 600 MPa for 2 min remained high until day 28. The overall results of this study demonstrate that HPP has the potential to preserve the quality of cauliflower.

Efficacy of Organic and Inorganic Fertilizers on Growth, Yield and Nutrient Uptake of Cauliflower in Acidic Soil of Bangladesh

Soil acidity is considered as one of the limiting factors in agricultural production because it affects plant growth and development by reducing the availability of essential nutrients. Therefore, a field trial was carried out at the experimental field of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur, Bangladesh from September 2021 to January 2022 to evaluate the effect of various organic and inorganic fertilizers on the growth, yield, and nutritional quality of cauliflower. The experiment was carried out in randomized complete block design with seven treatments viz. Control, Recommended dose of chemical fertilizers (RDF), Poultry Manure (PM) (3 t ha-1) + RDF, Vermicompost (VC) (3 t ha-1) + RDF, Cowdung (CD) (5 t ha-1) + RDF, Rice Husk Biochar (1 t ha-1) + RDF and Household waste compost (3t ha-1) + RDF with three replications. Among different treatments, the highest value for plant height (49.25 cm), number of leaves plant-1 (21.50), curd circumference (39.87cm), curd diameter (18.07 cm), marketable curd weight (777.57g plant-1), marketable curd yield (32.41 t ha-1), N, K, S content (1.92%, 1.87% and 0.33 % respectively) and K and S uptake ( 79.57 kg ha-1 and 13.92 kg ha-1) were recorded from the Household waste compost (3t ha-1) + RDF whose effect was statistically similar to the treatment Poultry Manure (PM) (3 t ha-1) + RDF. The maximum value for curd height (11.10 cm), N uptake (81.81 kg ha-1) and P content and uptake (0.32% and 13.97 kg ha-1 respectively) were recorded from poultry manure along with RDF. Whereas, the minimum value for all growth parameters, yield attributes, nutrient content and uptake were observed from unfertilized control. Therefore, integrated application of organic manures with synthetic chemical fertilizers can be practiced for attaining higher yield and better-quality curds compare to the sole application of inorganic fertilizers in acid soils of Bangladesh.

Effects of Nitrogen on Growth, Yield and Postharvest Quality of Selected Cauliflower (Brassica oleracea) Varieties

Cauliflower (Brassica oleracea var. botrytis L.) is one of the most popular vegetable crops. An experiment was conducted to study the response of late season varieties of cauliflower to different sources of nitrogen on growth, yield and postharvest quality at Rampur, Chitwan, Nepal during October 2018 to March 2019. Four late season varieties of cauliflower viz. NS 106, Snow Moon, Yukon, and Candid Charm and three different sources of nitrogen viz. 100% Nitrogen (N) through Farm yard manure, 50% N through FYM and 50% N through urea, and 100% N through urea. The two-factor experiment was laid in RCBD with three replications and twelve treatment combinations. All the recorded growth, yield and postharvest quality parameters were significantly higher and statistically similar in NS 106 and Yukon and significantly lower in Candid Charm. Similarly, significantly higher plant height, canopy diameter, leaf number, curd height, economic yield and biological yield were recorded in 50% N through FYM and 50% N through urea. Significantly lower plant height, canopy diameter, leaf number, economic yield and biological yield, titrable acidity and significantly higher days to curd maturity, vitamin C and dry matter content of leaf and curd, and TSS content were recorded in 100% N through FYM. Results revealed that for higher and postharvest quality of cauliflower during late season at Rampur, Chitwan Yukon or NS 106 both varieties were superior along with 50% N through FYM and 50% N than those of the other varieties.
