Evaluation of plastic mulches and botanicals and their efficacy on pest and disease incidence in okra var. Arka Anamika
A field experiment was conducted to evaluate the effects of different plastic mulches and botanicals on the incidence of pests and diseases of okra var. Arka Anamika at Uttar Banga Krishi Viswavidyalaya, West Bengal, India, during 2021 and 2022. The experiment included two factors, viz., the first factor- mulches (four levels) and the second factor- botanicals (five levels). The experiment was performed in a factorial randomized complete block design with three replications. The results of the experiment revealed that the treatment comprising silver plastic mulch along with foliar spray of Azadirachta indica leaf extract (5%) (M2B1) was most effective at reducing the incidence of yellow vein mosaic virus (1.82%), cercospora leaf spot (11.39%), whitefly population (30.94%, 43.49% and 57.29% reduction at 30, 45 and 60 DAS), jassid population (30.20%, 41.95% and 52.67% reduction at 30, 45 and 60 DAS) and fruit borer population (2.17) compared to the other treatment combinations. Hence, treatment with M2B1 (silver plastic mulch × 5% foliar spray of Azadirachta indica leaf extract) appears to be an effective eco-friendly approach for reducing pest and disease incidence and can be recommended for the commercial cultivation of okra in terai region of West Bengal.
STUDIES ON COMBINED EFFECTS AND EFFICIENCY OF MICROBIAL BIO-AGENTS WITH BOTANICALS AND CONVENTIONAL FUNGICIDES AGAINST MANGO ANTHRACNOSE (COLLETOTRICHUM GLOEOSPORIOIDES)
The present research study was undertaken to evaluate compatibility and comparative efficacy of different microbial bio-agents with botanicals as well as safer conventional fungicides against anthracnose in mango. Among fungal bio-agents viz. T. harzianum and T. virens observed compatible with azoxystrobin fungicide only, while bacterial bio-agents viz. Bacillus subtilis and P. fluorescens were found compatible with trifloxystrobin + tebuconazole. The present study also describes very effective approach of integrated disease management. However, three consecutive prophylactic spray was done with 10 days of pre-harvest intervals (PHIs) starting with mid of July for consecutive two crop seasons with in vitro most effective combi-biofungicides in which trifloxystrobin + tebuconazole (0.03%) + Bacillus subtilis (5%) was assayed highly efficacious with mean % disease index of 15.1 and 12.0 per cent with mean disease control 77.9 and 80.9 per cent at two different experiment location, respectively. Additionally, dip treatment of mango fruits after harvest in combined treatment consists of combi-biofungicides, trifloxystrobin + tebuconazole (0.03%) + Bacillus subtilis (5%) for the period of 5 minutes proven highly effective with 93.4 % Disease Reduction Index (DRI) which is followed by other combined treatment of trifloxystrobin + tebuconazole (0.03%) + P. fluorescens (5%), difenoconazole (0.012%) + P. fluorescens (5%) and with mean DRI 91.7 and 89.9 per cent, respectively. Overall, this research study underscores the importance of using efficacious combi-biofungicides in integrated manner which could be eco-friendly alternative over synthetic fungicides usage against fruit disease ensuring successful disease management in mango.
Meat quality of commercial broiler chicken as influenced by dietary supplementation of organic acids
A six-week feeding trial was conducted with 240 one-day old commercial broiler chicks to evaluate the effectiveness of replacing antibiotic growth promoters with organic acid salts on the carcass characteristics and meat quality. Treatment diets were supplemented with lincomycin HCl (4.4 ppm), bacitracin methylene disalicylate (BMD; 50 ppm), each two levels (ppm) of calcium propionate (1000, 2000) and coated sodium butyrate (500, 1000) either alone or in combination (1000+500) with control. Upon completion of the feeding trial, six birds from each treatment were slaughtered to study the carcass characteristics and meat quality. A non-significant difference was observed in live weight, blood loss, New York dressed weight, eviscerated yield, ready-to-cook yield, giblet weight and the cut-up parts. Meat quality parameters such as physico-chemical, microbiological (total viable count), proximate composition and sensory qualities also witnessed a non-significant difference among the treatment groups. Water holding capacity was significantly reduced in the groups supplemented with organic acid owing to apparent pH reduction. Organic acid supplementation slightly increased lightness (L*) value and leads to reduction in redness (a*) and yellowness (b*) without impairing the quality of meat. Favourably, organic acid and AGPs supplementation reduces the shear force value (kgf), hardness (kgf), gumminess (N) and chewiness (kgf.mm) than control groups. Based on the results, it can be concluded that salts of organic acids (OAs) could be supplemented as an alternative to antibiotic growth promoters (AGPs) in the commercial broiler diet without affecting the meat quality and sensory quality.
Pistacia lentiscus L. oil from the sub-arid region of Hodna (Algeria): Influence of oil extraction process on phenolic content, scavenging power, antibacterial and antifungal activities
This study aimed to evaluate, for the first time, the phenolic contents, antioxidant, antibacterial, and antifungal properties of the Hodna sub-arid lentisk seed oils obtained through hot (traditional method) and cold extraction techniques. The cold pressing process resulted in a much greater yield (15%) compared to the traditional method (5%). Both Hodna lentisk oils obtained by cold pressing (HLCO) and hot extraction (HLHO) were rich in polyphenols, but the total phenolic content of HLCO (94.54 mg GAE/100 g) was twice that of HLHO (48.02 mg GAE/100 g), making HLCO a richer source of phenolic compounds. HLHO and HLCO showed very high free radical scavenging activity, which were respectively 113.81 and 107.47 mM TE/100 g. Limited inhibitory effects were observed against a panel of five pathogenic bacteria and six fungal strains. The sub-arid origin of P. lentiscus oils, more particularly the cold-extracted one, may be a natural source of promising phenolics compounds that could be incorporated into new products or replace synthetic compounds in the health, food, and cosmetics sectors.
The Impact of Strip Tillage Method Applied in Cotton Cultivation on Plant Emergence Parameters in the Çukurova Region, Ceyhan Plain
Considering the increasing global population and the importance of food security, it is crucial to develop sustainable agricultural production systems that reduce greenhouse gas emissions, are climate-resilient and sensitive, prevent erosion, and conserve soil. This study aims to compare strip tillage, one of the conservation tillage techniques, with conventional tillage in terms of plant emergence parameters and yield in cotton cultivation. The research was conducted between the 2023–2024 on an experimental field located in the Ceyhan Plain of the Çukurova Region. Cotton (Gossypium hirsutum L.) was used as the plant material. The results showed that the highest mean emergence date was observed in the conventional tillage method (12,61 days). In other words, plant emergence occurred in a shorter time (11,88 days) with the strip tillage method compared to conventional tillage. The emergence rate index was higher in the strip-till method (2,09 plants/day m). Regarding the percentage of emergence, the highest value was observed in the strip tillage method (%99,95), while the lowest value was recorded in the conventional tillage method (%91,50). In terms of yield, conventional tillage an average yield of 472,5 kg/da −1, while strip tillage resulted in an average yield of 461 kg/da −1. In conclusion, cotton plants grown using the strip tillage method demonstrated better performance in terms of plant emergence parameters. The strip tillage method, which is sustainable, protective, restorative, environmentally friendly, and economical, should be promoted as an alternative to conventional tillage practices.
