Influence of Forage Radish Cover Crop on Growth and Yield of Vegetable Crops in an Intensive Vegetable Cropping System

Paper ID- AMA-07-12-2022-11871

Radish mostly forage radish (Raphanus sativus L.var. longipinnatus) cover crop (CC) being a short-duration crop can be easily incorporated into the vegetable cropping system for sustainable production of vegetable crops. In the present experiment, the incorporation of forage radish CC biomasses before and after the harvest of vegetable crops provided numerous benefits. Vegetative growth and yield attributing parameters in terms of plant height, branch number, average fruit number, average fruit weight, stem diameter etc. of okra, bitter gourd, chilli, dolichos bean, amaranthus and cowpea were found to be higher in CC treatment compared to bare fallow control devoid of CC. Among the different levels of CC used complete ground cover with cent percent CC recorded better in terms of growth and yield attributes compared to 75 and 50 percent surface cover. The yield of vegetable crops in the cropping system was found to be positively influenced by the levels of forage radish CC compared to the non-adoption of CC in the control. The crop duration of the vegetable crops was also enhanced by the use of CC compared to control devoid of CC, and the harvesting duration of vegetable crops was prolonged due to the use of CC. For sustainable vegetable crop production with 200% vegetable cropping intensity in the sandy soil of Gossaigaon, Assam, India forage radish CC (Raphanus sativus var. longipinnatus), syn. Daikon or Japanese radish can be used as CC before sowing spring-summer and summer season vegetable crops.

Pathogenicity and Toxicity of Metarhizium anisopliae (Metchnikoff) Sorokin against Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) under in vitro conditions

Paper ID- AMA-07-12-2022-11870

The Helicoverpa armigera, Hubner (Lepidoptera: Noctuidae), is the most important economic pest. In the larval stage, the pest feeds on tomato fruits and seriously damages the fruits. Therefore, to reduce the overuse of chemical pesticides in tomato crops, microbial control is a key ingredient for sustainable crop production. Most toxic substances produced by microbial pathogens have been identified as peptides, but they are very different in terms of structure, toxicity and specificity. Therefore, the objective of the present investigation was to determine the bioefficacy of the entomopathogenic fungus, 12 Metarhizium anisopliae (Metchnikoff) Sorokin, isolates against 2nd instar larvae of the tomato fruit borer Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) under in vitro conditions. In vitro studies an bioefficacy of 12 Metarhizium anisopliae (Metschnikoff) (Sorokin) isolates (M1, M2, M3, M4, M5, M6, M7, M8, M9, M10, M11 and M12) at four different concentrations of 1x1010, 1x109, 1x108, 1x107 against 2nd instar Helicoverpa armigera (Hubner) larvae revealed that all the strains were pathogenic to the target pest at all spore concentrations. However, among them isolates M3 and M7, were most effective and recorded 95 and 85% larval mortality with LT50 value of 47.82 and 56.75 hours at the lowest spore concentration (1x1010 spores ml-1) and LC50 values of 5.06x105 and 2.29x107 spore ml−1, respectively. The lowest mortality (62.50%) was recorded in isolate M4 at 5 days after inoculation. These findings suggested that the adverse effect of most virulent M. anisopliae isolates M3 and M7 were compatible and most virulent to the target pest and that the simultaneous use may be helpful for managing H. armigera, 2nd instar larvae.

Role of Potash nutrient in the management of Cassava Mosaic Virus Disease caused by Cassava Infecting Geminiviruses (CIGs)

Paper ID- AMA-07-12-2022-11869

Cassava (Manihot esculenta Crantz.) is one of the major tuber crops in tropical and sub-tropical Africa, Asia and Latin America where it is the basic staple crop for 500 million people. The major constraint in cassava production in India and Africa is Cassava mosaic disease (CMD) caused by Cassava infecting geminiviruses (CIGs) belonging to the family of Geminiviridae and Genus Begomovirus which is transmitted by whitefly Bemisia tabaci Genn. A study was carried out to manage the Cassava Mosaic Disease with graded doses of potash nutrient. In this study, least disease incidence (34.33 per cent), least disease severity (1.21), least concentration of Cassava mosaic virus (0.450), maximum plant height of 117.56 cm and maximum cassava tuber yield of 43.00 t/ ha were recorded in the cassava plants applied with 45:90:320 kg of NPK / ha as basal dose and 45:320 kg of NK / ha during split application at 90 DAP as against control (45:90:0 kg of NPK / ha as basal dose and 45:0 kg of NK / ha during split application at 90 DAP) [95 per cent, 4.53,1.947, 58.94 and 20.35t/ha respectively).

IMPROVEMENT OF SILKWORM GROWTH AND COCOON PARAMETERS THROUGH FORTIFICATION OF PROBIOTICS

Paper ID- AMA-07-12-2022-11867

Probiotics are the live microbial food supplements which improves the microbial balance and enhanced rapid cellular growth and development. Commercial probiotics viz., Lactobacillus rhamnosus, Saccharomyces boulardii and Bifidobacterium longum with six different concentrations (0.5, 1.0, 1.5, 2.0, 2.5 and 3.0 %) were used to fortify the mulberry leaves, fed to silkworm and studied its impact on gut population, enzymatic activity and economic parameters. Among the different concentrations, 3 % recorded maximum bacterial population, amylase activity and improved economic parameters in all the probiotics treated CSR 2 larvae. Among the three probiotics, Bifidobacterium longum @ 3 % recorded highest gut population of 3.11 x 107 cfu/ml and 3.56 x 107 cfu/ml in fourth and fifth instar larvae. amylase activity (64.79 mg/g) and economic parameters like cocoon weight (1.52 g), Pupal weight (1.20g), shell weight (0.32 g) cocoon weight and shell ratio (21.05 %) respectively. The present findings of the study strongly suggested that fortification of probiotics to silkworm through mulberry feed enhances gut microbes, enzyme activity thereby economic parameters of silkworm.

Influence of housing system on the production performance of commercial broilers fed with different levels of energy and protein

Paper ID- AMA-07-12-2022-11866

A biological experiment was conducted to optimize the energy and protein requirement for commercial broilers in environmentally controlled housing system. The experiment was conducted by feeding diets with different levels of energy (2850, 2950 and 3050 kcal/kg in pre-starter diet, 2950, 3050 and 3150 kcal/kg in starter diet and 3050, 3150 and 3250 kcal/kg in finisher diet) and protein (21.5, 22.5 and 23.5% in pre-starter diet, 20.5, 21.5 and 22.5% in starter diet and 19, 20 and 21% in finisher diet) to commercial broilers for a period of five weeks to assess the production performance. The biological experiment was carried out with five hundred and seventy six (each 288 in environmentally controlled deep litter house and open sided deep litter house), sex separated, day-old, commercial (Vencobb 400) broiler chicks belonging to single hatch. The chicks were wing banded, weighed and randomly allotted into nine treatment groups with four replicates of eight chicks each and housed in both environmentally controlled and open sided housing systems. All chicks were reared up to 5 weeks under standard managemental conditions. During this experimental period, data on body weight and feed consumption were recorded at weekly interval and mortality was recorded at occurrence. The results of the experiment revealed that the energy and protein content of the diet had significantly influenced the body weight gain, feed consumption and feed conversion ratio in broilers irrespective of the system of housing. The broilers reared in environmentally controlled housing system had comparatively higher body weight (2022.19g Vs 1819.25g) and better feed conversion ratio (1.37 Vs 1.47) than the open sided housing system. The housing systems and feeding plans in this study also had significantly influenced the body weight gain, feed consumption and feed conversion ratio, which are all favourable in environmentally controlled housing system.
