Study on the Effect of Organic and Inorganic Fertilizer with Biofertilizer on Crop Growth and Yield Attributing Performance of Sprouting Broccoli under Central Uttar Pradesh Condition

Paper ID- AMA-02-09-2023-12565

A field experiment was conducted during the Rabi season 2018–2019 and 2019–2020 at Vegetable Research Farm, Department of Vegetable Science, Chandra Shekhar Azad University of Agriculture and Technology, Kanpur Uttar Pradesh 208002, India. It comprised twelve treatment levels of fertilizer in a randomized block-design with three replications. The growth parameters of the sprouting broccoli crop were significantly affected by the fertilizer treatments. Maximum plants height viz. (28.19 cm, 49.39 cm, and 51.19 cm), number of leaves per plant (9.48, 16.81 and 18.84), length of leaf (9.55 cm, 47.54 cm, and 48.93 cm), the width of a leaf (5.99 cm, 21.61 cm, and 24.09 cm) and maximum plant spread (37.30 cm, 59.78 cm, and 69.13 cm) respectively at 30, 60 days after transplanting and at harvesting stage were observed in treatment (T8):-Vermicompost @ 5 tons/ha + Azotobacter @ 2 kg /hectare and minimum value were under control conditions (T0). Yield and yield contributing characters like days taken to first head initiation (51.15 days), days taken to 50% head initiation (55.16 days), days taken to head maturity (72.11 days), stalk diameter (3.52 cm), stalk length (21.39 cm), head diameter (12.62 cm), head length (7.25 cm), head width (12.89 cm), weight of head with jacket leaves (1283.20 g), weight of head without jacket leaves (510.88 g), (%) loss of head weight (g) stored at room temperature (6.44%), marketable yield (6.21 kg/plot) and head yield (186.99 q/haetc. were highest in treatment (T8): Vermicompost @ 5 tons/ha + Azotobacter@2 kg / hectare.

Influence of Passive and Static Composting Methods on Microbial Profiles of Compost from Caged Layer Manure With Biochar and Coconut Coir Pith Waste as Co-Composting Materials

Paper ID- AMA-01-09-2023-12564

This experiment aimed to assess the microbial changes in composting caged layer manure (CLM) using passive and static aeration, incorporating biochar and coconut coir pith waste (CCP). This study was conducted at the Livestock Farm Complex, Veterinary College and Research Institute, Namakkal, India, across summer and monsoon seasons, compost piles were formulated based on specific C:N ratios. CLM was blended with carbon-rich materials, and samples were collected at start and end of the the composting process. This study revealed significant reductions (P ≤ 0.05) in total bacterial and total Coliform counts at the end of composting period. This environmentally safe approach highlights composting's efficacy in converting organic waste, like CLM, into beneficial organic fertilizer, emphasizing its potential for sustainable waste management.

Stable general and specific combiners and performance of their heterotic combinations across environments in pigeonpea (Cajanus cajan (L). Millsp.)

Paper ID- AMA-31-08-2023-12563

This study was undertaken under varied environments to estimate the general and specific combining ability of different female and male lines in cross combinations for important economic traits and estimate heterosis for developing superior hybrids. The 45 hybrids and their parents were evaluated at four environments: two different planting dates. The obtained data showed, highly significant differences among parents, F1 crosses and parents versus crosses over all environments. An evaluation of general combining ability variance components as estimated from male and/or female across environments were larger than those of specific combining ability for days to 50% flowering, days to maturity, plant height, primary branches/plant and secondary branches/plant indicating the presence of additive gene action. However, opposite results were obtained for pods/plant, seeds/pod, 100 seed weight and seed yield/plant. The line ICPA 2089 and testers ICPL 161, ICPL 88039, ICPAL 88034 and ICPL 81-3 were found desirable general combiners for days to flowering and maturity. While ICPL 20093, ICPL 161, ICPL 20108 and ICPL 20177 best general combiners for seed yield and its component traits. For seed yield, ICPA 2047 × ICPL 20128 and ICPA 2089 × ICPL 20166 were the best specific combinations with higher per se performance values. The cross, ICPA 2047 × ICPL 20128 found to be best specific combiner for flowering and yield traits. The best hybrids based on heterotic values were ICPA 2047 × ICPL 20128 and ICPA 2047 × ICPL 20177. These two hybrids surpassed standard check in their performance for most of the yield and its related traits and after adequate testing across locations, these hybrids can be recommended for commercial exploitation for pigeonpea production.

Evolution of soil organic carbon under different cropping systems in hot arid region, India

Paper ID- AMA-30-08-2023-12561

The study was conducted to evolution of soil organic carbon under different cropping systems in hot arid region, India. SOC ranged from 1.8 to 4.9 g kg-1 with mean value of 3.0 g kg-1. Guar-wheat (3.90 g kg-1) cropping system possessed significantly higher SOC content. pH values of soil ranging from 7.9 to 8.7 with mean value of 8.1. electrical conductivity (EC) value varied from 0.4 to 6.2 dS m-1 with mean value of 0.5 dS m-1. Cation exchange capacity (CEC) in soils of arid egions varied from 2.6 to 6.8 cmol (p+) kg-1 with mean value of 5.0 cmol (p+) kg-1. available nitrogen content varied from 810.6 to 102.3 kg ha-1with mean value of 61.4 kg ha-1 whereas the available phosphorous ranged from 8.5 to 24.8 kg ha-1 with mean value of 17.2 kg ha-1. Wheat based cropping systems ground-wheat (19.50 kg ha-1) and guar-wheat (19.43 kg ha-1) had significantly higher available phosphorous. Guar-wheat cropping systems maintained significantly higher (248.30 kg ha-1) available potassium content. soil organic carbon was significantly positive correlated with cation exchange capacity available nitrogen phosphorus and potassium.

Comparative Evaluation of Epiphytic Yeast for the Management of Fruit Rot of Chilli under Field and Pot Conditions

Paper ID- AMA-30-08-2023-12560

A total of 160 epiphytic yeast strains associated with various genotypes of chilli (Capsicum spp.) cultivated in Meghalaya, India, were isolated and subjected to assessment for their antagonistic potential against a pathogenic strain of Colletotrichum truncatum, causal agent of fruit rot in chilli. Notable variations were observed in the inhibition of mycelial growth of the pathogen through a dual culture assay, with mean inhibition per cent ranging from 31.55% to 64.81%.Four distinct yeast isolates, namely YE12 (identified as Saturnispora sylvae), YE46 (identified as Meyerozyma guilliermondii), YE64 (identified as Rhodotorula paludigena), and YE127 (also identified as Meyerozyma guilliermondii), were chosen for subsequent evaluation in controlled pot experiments as well as under field conditions. Notably, the synergistic application of these efficient yeast isolates exhibited superior outcomes compared to their individual applications. Among all the single and combined treatments, the consortium comprising the four yeast isolates, i.e., YE17+YE46+YE64+YE127, demonstrated the highest reduction in disease incidence, with a substantial decrease of 77.85% in the pot experiment and 64.57% reduction in the field experiment, respectively. Furthermore, the treatment involving the combination of Saturnispora silvae, Meyerozyma guilliermondii, Rhodotorula paludigena, and Meyerozyma guilliermondii exhibited notable improvements in both plant health and yield attributes across both experimental conditions.
