Ecology of seed dormancy and germination in Rice flat sedge (Cyperus difformis L)

Paper ID- AMA-10-01-2023-11951

Specific knowledge about seed dormancy, germination and emergence patterns of weed species aids in the development of integrated management strategies. Laboratory studies were conducted to determine the effect of environmental factors on seed germination and seedling emergence of Cyperus difformis (rice flat sedge). The objective of this experiment was to identify an effective method to break the innate dormancy of fresh seeds, in order to achieve uniform germination. For this, various physiological seed dormancy breaking treatments viz.,GA3, KNO3, Thiourea and distilled water were imposed to the seeds with various concentrations of solution and duration of soaking. Untreated dry seeds served as control. The results were revealed that all physiological treatments used in this study improved the germination. Among them, the superior performance was registered by soaking the seeds in the GA3 @ 600 ppm for 12 hrs. With the germination of 92 per cent. Whereas, the control seeds were recorded nil germination.

Evaluation of Antimicrobial activity of the Combination of Dolomite and Turmeric in the ratio 9:1 against the environmental isolates of sensitive and resistant Aeromonas hydrophila.

Paper ID- AMA-10-01-2023-11949

In order to the treat increasing diseases in a milieu of global emergence of antimicrobial resistance, sustainable eco-friendly alternatives are urgently needed. Thus, in-vitro evaluation of the therapeutic feasibility and employability of environmental- friendly compound, a combination of dolomite and ethanolic extract of turmeric in the ratio 9:1, against aquatic environmental isolate (antibiotic resistant and sensitive) of Aeromonas hydrophila was performed. The bacteria were isolated and characterized from fish farms in Ernakulam district, Kerala. The antimicrobial activity of the compound was assessed by the resazurin based broth microdilution to determine minimum inhibitory concentration (MIC). Time-kill kinetics assay performed at varied concentrations of 1xMIC,2xMIC and 4xMIC concentrations. Also, the crystal-violet based biofilm inhibition assay was performed. Exposure study was performed at sub-lethal concentration of 0.5xMIC. MIC of the combination was found to be at 64 µg/ml and 4096 µg/ml against the sensitive and resistant A.hydrophila respectively. Time-kill kinetics assay showed the bacteriostatic effect of the compound. Biofilm inhibition assay confirmed the ability of compound to reduce the biofilm formation propensity of the bacterial community. The exposure study performed at sub-lethal concentration of 0.5xMIC showed no changes in the resistance pattern. The results of the study validate an eco-friendly alternative for antibiotic use in aquaculture.

Biochemical and morphological basis of jassid (Amrasca devastans Dist.) resistance and inheritance in cotton (Gossypium hirsutum L.)

Paper ID- AMA-06-01-2023-11945

Four jassid resistant varieties (lines) were crossed with three high yielding adapted varieties (testers) in a Line x Tester fashion to elucidate morphological (trichome density and gossypol gland density) and biochemical (tannin, total phenols and gossypol content) basis of jassid resistance in cotton. The female parent KC 2 recorded high amount of trichome density, gossypol gland density, tannin, total phenols and gossypol content indicating that the parent KC 2 was highly resistant to jassid. Among the hybrids screened, the hybrids KC 2 x MCU 5, KC 2 x MCU 12, KC2 x MCU 7, SVPR 3 x MCU 5 and Khandwa 2 x MCU 12 were found to be moderately resistant under artificial epiphytotic condition. The correlation between jassid susceptibility grade and trichome density, gossypol gland density and tannin content was negative and significant while far between total phenols and gossypol content with jassid susceptibility grade. The inheritance study indicated that resistance in the parents was due to monogenic dominance or digenic interaction. The morphological and biochemical basis of resistance revealed that the high density of trichomes, total phenols, and gossypol gland density constituted the mechanism of resistance in cotton.

Profitability of intercropping system in elephant foot yam with short duration vegetables

Paper ID- AMA-05-01-2023-11941

Elephant foot yam, “The king of tubers”, is a wider-spaced, long duration crop with immense nutritive and therapeutic values. Its initial growth phase is slower and takes 60 days or more to spread. Thereby its inter-spaces can be utilized to grow short duration vegetables crops. In this regard, field experiments were conducted at Horticultural College and Research Institute, Coimbatore during two different season (2021 and 2022). Here five treatments including mono-cropping of elephant foot yam (CS1) and intercropping of elephant foot yam with cluster bean (CS2), radish (CS3), amaranthus (CS4) and fenugreek (CS5) were taken and replicated four times. The design of the experiments was randomized block design. The intercropping systems in elephant foot yam exhibited higher profit when compared to mono-cropping. The higher gross return of Rs 518950 and Rs. 429750, net return of Rs. 371325 and Rs. 282125 and B:C ratio of 1:2.29 and 1:1.74 was noticed in season I and Season II respectively when cluster bean is inter-cropped in elephant foot yam. Thus, growing cluster bean with elephant foot yam is recommended for higher profitability.

Analysis of the Need for Agricultural Machinery Based on Region and Commodity in Indonesia

Paper ID- AMA-05-01-2023-11940

The objectives of this study are: 1) To assess the potential uses of agricultural machinery, 2) To identify the number and distribution of government machinery aid in Indramayu, and 3) To need analyze of machinery based on a potential commodity. The results of the descriptive analysis revealed that the level of use of agricultural mechanization for rice cultivation in Indonesia in 2018 was an average of 60.5%, where the level of use of agricultural mechanization in 17 provinces in Indonesia had exceeded the national average. The population of the machineries continues to increase where in 2014 the number was only 12,501 units, but in 2020 the number jumped to 365,328 units. Compared to the availability of machineries, there are quite a lot of gaps, namely for tractor as many as 2565 units, thresher 3834 units and combine harvester as many as 1000 units. The policy recommendation are presented.
