Phytophthora leaf blight resistance sources in Capsicum annum Leo. and determination of isolate mating type

Paper ID- AMA-26-07-2023-12478

Phytophthora blight and root rot caused by Phytophthora capsici are two independent major disease syndromes in capsicum which cause 40-100 % yield loss in open field conditions and protected structure. The key objective was to develop resistant sources against the P. capsici oomycetes but due to the association of multiple independent pathogens, first we have decided to screen out the lines for blight from locally available isolates in India. Therefore, in the present investigation, we have identified four resistant (0-5%) i.e., AV-143, 116, 132 and 133and one moderately resistant line name AV-144 line (5-10%) from germplasm imported from World Vegetable Centre (AVRDC), Taiwan and two lines CPCT-84 and CPCT-144 from F3segregating population against the P.capsiciisolates collected from Karnataka, South India. The characterized strain of P.capsici was the A1 mating type collected from south India.

Evaluation of Growth Retardant in Hastening the Maturity of Groundnut

Paper ID- AMA-25-07-2023-12477

Groundnut (Arachis hypogaea L.) is a self-pollinated, auto-tetraploid legume crop with 2n=40 chromosomes and belongs to the family Fabaceae. Mepiquat chloride (MC) is an important growth retardant inhibits vegetative growth and accelerates the development of reproductive parts by reducing plant height, thereby decreasing the distance between the source and sink, resulting in better translocation of photosynthetic into developing pods, which is expected to improve groundnut harvest index. Hence the present study, was conducted on SG99 to test the efficacy of growth retardant mepiquat chloride at five concentrations (100,300,500,700 and 900 ppm) keeping check as control. Single foliar spray of mepiquat chloride was given at 40, 60 and 80 DAS. The growth retardant, mepiquat chloride @700ppm significantly reduced days to initiation of flowering, 50%, completion flowering for 4.0 days whereas SPAD value increased by 4.32%. Similarly, Physiological data recorded at 60 and 90 DAS revealed that plant height, root length, root weight was decreased with mepiquat chloride @700 ppm. However, number of branches, nodules number, and nodules weight, dry weight of root, leaves and shoot were more with mepiquat chloride @700 ppm over control. Hence, our results revealed the effective concentration was 700 ppm of the growth retardant.

Influence of Moringa Oleifera Leaf Meal on the Performance of Layer Japanese Quails (Coturnix Coturnix Japonica)

Paper ID- AMA-24-07-2023-12473

The potential influence of Moringa oleifera leaf meal on the performance and cost economics of layer Japanese quails was evaluated in the year 2020-21. A sufficient quantity of crude protein (30.21%) and fiber (8.12%) were found in the M. oleifera leaf meal. Statistical analysis at the end of sixteen weeks experiment revealed that growth characteristics, nutrient utilization, production, and carcass characters exhibited significantly enhanced values in M. oleifera leaf meal-incorporated diets. The liver and kidney function tests exhibited no organ toxicities in the birds following the dietary incorporation of M. oleifera leaf meal. On top of it, M. oleifera leaf meal-incorporated diets showed a reduction in feed cost per kg egg production in the range of Rs. 20.91-56.17. Of various inclusion levels used in the experiment, 2% was found best for all the parameters studied. At last, M. oleifera leaf meal can be recommended in the diet of layer Japanese quails as a safer, eco-friendly, and cost-effective technology.

Optimization of plant density and nutrient level for nutritional quality of guava under high density system of orcharding in subtropical conditions

Paper ID- AMA-24-07-2023-12472

Grafted plantlets of guava were planted at a density of 4444, 5000, 6666 and 10000 plants ha-1 to standardize the optimum population density and nutrient level for nutritional quality of guava under subtropical conditions of northeast India. The experiment was set up at the AAU–Horticulture Research Station, Assam, India with two factors comprising four planting densities and three nutrient levels, and twelve treatment combinations with three replications were imposed on newly planted guava plants. The plants accommodated at lower densities produce superior quality fruits in respect of all chemical constituents throughout both seasons. The fruits of the plant at density 4444 plants ha-1 in winter and 5000 plants ha-1 in rainy season were found to contain the highest amount of TSS (11.63 & 10.73ºB), reducing sugar (4.66 & 4.46%), total sugar (8.27 & 7.85%), ascorbic acid (202.75 & 196.47 mg/100 g) and pectin (1.17% & 1.08%) respectively in the first year and the trend was reversed in the second year and plants under the highest density (10000 plants ha-1) yielded fruits with lowest qualitative traits irrespective of season and year. The nutrient level also had a significant influence on the quality attributes of fruit, an increased trend was observed with increasing level, and the highest nutrient level (70:45:35g NPK plant-1 for the first year and 130:75:65g NPK plant-1 for the second year) demonstrated significant superiority. The winter season crop was superior to rainy season in terms of chemical characteristics of fruit during both years of investigation.

Genetics of immune-competence traits in a complete 3x3 diallel cross of Indian native chicken breeds with CARI-Red

Paper ID- AMA-24-07-2023-12470

Two Indian native chicken papulation, Aseel Peela (AP), Kadaknath (KN) and one exotic papulation, CARI-Red (CR) maintained at ‘Desi fowl’ unit of ICAR - Central Avian Research Institute were utilized for making full 3x3 diallel cross experiment. General immune-competence of birds (Sample size - 30 birds per genetic group) was evaluated as humoral response as well as cell mediated immunity (CMI) response. The humoral response was studied by estimating the RD-HI antibody titres by Haemagglutination inhibition test [1], while CMI response was estimated as food index [2] against the injection of mitogen (PHA-P). Full diallel analyses were done by using two models model A and model B. Higher values of foot index indicated presence of better cell mediated immunity response to PHA-P and higher values of HI titre indicate better humoral immunity against NDV. The analyses of variance for cell mediated immune response and humoral immune response revealed highly significant difference for GCA at 15 wk of ages in male, female and combined sex in case of model A and B which indicates the additive type of genetic variation. Cross KN x AP had higher and positive Heterosis percentage for cell mediated immune response against PHA-P. In case of humoral immune response against NDV cross CR x AP had highest Heterosis percentage than other crosses.
