Professional Competence of Extension Personnel in Punjab State
Agriculture is a vital sector of India's economy, contributing 20.2 percent to the country's Gross Value Added. In light of the increasing demand for food products due to ever increasing population, extension personnel need the latest knowledge and skills to educate and train farmers. This study was undertaken with the objective of measuring the professional competence of extension personnel. The sample consists of trainees from various training programmes regarding competency development organized by PAMETI in 2017–2018. 5 trainings were chosen by purposive sampling from the list procured by PAMETI. 24 trainees each from 5 different trainings were selected by random sampling method. Thus, a sample of 120 trainees from PAMETI and PAU Ludhiana was selected for the final data collection. The majority of the trainees possessed high human relations, communication, motivation, and supervising skills, whereas the majority possessed medium technical expertise, planning, leadership, coordination, conflict-management, and organizing skills. It was found that the average competence index is highest for human relations skills, whereas the average competence index is lowest for organizational skills. The majority of the trainees were perceived to lie in the medium category of the overall competence index, followed by the high and low categories.
Nanotechnology for health management in aquaculture
The increase in antimicrobial resistance and the chemical residues in tissues of the cultured fishes from the chemotherapeutants used in aquaculture, has led to the investigation of new alternatives which could be used for treating the diseases of aquaculture system. Several studies were carried out to discover a better health management tool in aquaculture. Nanotechnology which is a field of science and technology which is now being used in many systems. Currently the use of nanotechnology is increasing in many fields such as engineering, agriculture and other food production sectors. The use of nanotechnology in aquaculture is also increasing in the present years. Nanotechnology application in aquaculture serves to be an effective eco-friendly alternative to the antibiotic and chemotherapeutant usage in aquaculture. Nanoparticles can be applied in aquaculture in several ways, through the direct introduction into water or added in through the feed and given to fishes. It is known to enhance the growth, improve the immune status, disease prevention, disease detection and management in the system. The nanotechnology could serve as a possible tool for health management in aquaculture. This article gives a review on the use of nanotechnology in aquaculture.
Ecology of seed dormancy and germination in Rice flat sedge (Cyperus difformis L)
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.
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.)
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.
