Evaluation on management module against leaf hopper complex in Mango crop
Mango (Mangifera indica L) is an important crop grown in different parts of India. Mango hopper is a major pest of mango causing seviere yield losses. As the losses due ot mango hopper could be as high as 65 per cent in the absence of control measures, many insecticides have been recommended world-wide to control the pest. On farm trials were conducted by Krishi Vigyan Kendra, Namakkal to assess the management modules against leaf hopper in mango crop in terms of incidence of shredding of flower buds and flowers damage percentage, destroying the inflorescences and causing fruit drops, curling and drying of infested tissue, development of shooty mold and fruit yield per hectare during Kharif 2020 in Namakkal district. The treatment comprises T1-Spraying of Oil based Metarhizium anisophilae @ 1ml/ litre of water at 3 times per weekly interval + Setting of yellow sticky trap @ 25 nos./ha (IIHR, 2017); T2- Neem oil @ 5ml/litre or Nimbicidine 1500 ppm @ 4ml / litre at 2 times per weekly interval + setting of Yellow sticky Trap @ 25 numbers/ha recommended by (Tamil Nadu Agricultural University, 2016); T3 – (Farmers practice) spraying of Lamdacyclothrin @ 2ml/ litre; Imidachloprid @ 0.5 ml/ litre with wettable sulphur @1 ml /litre and Proponophos @ 1ml /litre + yield win tonic combination of insecticides 3 times per weekly interval packages. The study revealed that mango crop sprayed with oil based Metarhizium anisophilae @ 1ml/ litre of water at three times weekly interval + setting of yellow sticky trap @25 nos./ ha effectively controlled @ 3.4 number of leaf hopper /panicles in a single branch of trees at 15 days after spray; reduced number of young fruit dropped per tree @ 8.6 number; number of number of moths trapped in a single yellow sticky trap is 5.8 numbers; total fruit harvested /tree is 1402 with higher fruit yield of 106 quintal/ hectare as compared to other practices. Whereas the farmers practice of spraying Lamdacyclothrin @ 2ml/ litre; Imidachloprid @ 0.5 ml/ litre with wettable sulphur @1 ml /litre and Proponophos @ 1ml /litre + yield win tonic combination of insecticides at 3 times at weekly interval recorded 5.2 number of leaf hopper /panicles in a single branch of trees at 15 days after spray; number of young fruit dropped per tree @ 11.4 number; total fruit harvested /tree is 1146 with higher fruit yield of 95.2 quintal/ hectare in kharif season.
Jackfruit (Artocarpus heterophyllus) Powder Enhances Tenyi Vo Pig Growth and Profitability
Rising feed costs threaten the sustainability of pig farming in Nagaland, India, where the indigenous Tenyi Vo pig is a vital livelihood source. This study evaluated the effects of jackfruit (Artocarpus heterophyllus) powder supplementation on growth performance and economics in Tenyi Vo pigs. Twenty weaner piglets (60 days old) were assigned to four groups: T1 (control, concentrate feed), T2 (25 g/kg jackfruit powder), T3 (50 g/kg), and T4 (75 g/kg) for nine weeks. Growth parameters included body weight, weight gain, and feed intake; economic metrics included production costs, net profit, and benefit-cost ratio (BCR). The T4 group achieved the highest final body weight (8.80 kg), weekly weight gain (1.16 kg/pig/week), and net profit (Rs. 1910.6/piglet) with a BCR of 1.58 (P<0.05). Feed intake was highest in T3 (10.47 kg total). Jackfruit powder at 75 g/kg significantly enhances growth and profitability, offering a cost-effective feed strategy for smallholder farmers.
Studies on effect of integrated nutrient management on growth and yield attributes of tomato (Solanum lycopersicum L.)
A field experiments were carried out to study the effect of integrated nutrient management on growth and yield attributes of tomato cv. Kashi Aman at Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi, Uttar Pradesh during Rabi season 2020-2021 and 2021-22 in Randomized Block Design with twelve treatments. The treatments were allotted separately at random in all the three replications at distance of 60 × 50 cm. The results revealed that significantly highest growth and yield attributes were recorded with application of treatment T7-75% recommended dose of fertilizer + 25% vermicompost along with biofertilizers (Azospirillum + PSB @ 2.5 kg/ha each). However, maximum plant height at harvest was registered under (100%) recommended dose of fertilizer which was at par with treatment T7- (75%) recommended dose of fertilizer + (25%) vermicompost + biofertilizers inoculation (Azospirillum + PSB @ 2.5 kg/ha each).
Studies on Osmotic Dehydration and Air-Drying Characteristics of Aloe Vera (Aloe Barbadensis) Gel
In this study the effect osmotic dehydration followed by drying on the physicochemical properties of aloe vera (Aloe barbadensis) gel was evaluated. The aloe vera gel cubes were osmotically dehydrated in sucrose of concentration 40-60B at room temperature and at 40C. The osmotically dehydrated aloe vera gel cubes were then air dried and the quality characteristics of the dried gel cubes were studied. The osmotic dehydration kinetics revealed that the logarithmic model represented the mass transfer kinetics of the aloe vera gel cubes both. It was also observed that the increase in sucrose concentration and osmosis temperature increased the solid gain and water loss ratio in aloe vera gel cubes. The air-drying characteristics of the aloe gel cubes revealed that the osmosis time increased the drying rate irrespective of the sucrose concentration and osmosis temperature. Further, the osmosis time, temperature and solute concentration reduced the water activity of the aloe vera gel cubes after air drying. However, the rehydration ratio of osmo-air dried sample decreased significantly with the increase in sucrose concentration, time and temperature.
Development of Chlorine free Extracted Nanocellulose based edible coating for increasing shelf life of banana
This study optimized the extraction process, achieving a yield of 83% cellulose and 76% nanocellulose using 8% sodium hydroxide (NaOH) solution and 90% ascorbic acid. The methodology began with grinding 200–250 g of rice husk into a fine powder and adjusting its moisture content to 35% for efficient processing. The moistened sample is soaked and passed through a food extruder to break down its structure further. Alkali treatment with 8% NaOH at 50°C for 2.5 hours removes lignin and hemicellulose. The material is then washed with distilled water until neutral pH is achieved. Bananas, one of the most widely consumed fruits worldwide, are highly perishable, with a rapid ripening process that leads to significant postharvest losses. Enhancing their shelf life is crucial to reducing food waste, improving marketability, and meeting consumer demands for fresh produce. This study investigates the development of cellulose- and nanocellulose-based edible coatings, incorporating glycerol, Tween 80, katira gum, and distilled water in varying proportions, to evaluate their effectiveness in preserving banana quality during storage. The most effective composition contained 8% nanocellulose, 0.5% katira gum, 5% glycerol, 1% Tween 80, and distilled water. This formulation significantly delayed ripening, maintained firmness, reduced weight loss, and preserved overall quality by forming a uniform, thin layer that minimized moisture loss and reduced respiration rates.
