STANDARDIZATION OF EFFECTIVE MANAGEMENT METHODS FOR MELOIDOGYNE ENTEROLOBII IN HIGH DENSITY PLANTING OF GUAVA ORCHARD
Guava (Psidium guajava) ensures India’s nutritional security by satisfying the dietary needs of people and is cultivated all over the world due to its nutritional and economic importance. In many cases, guava was found susceptible to various pests, diseases, and nematodes. Among them, Root-knot nematode (RKN) is the devastating nematode infesting guava. The guava orchard of MITCAT Farm, Musiri, TN was found to suffer severe yield loss and loss of trees. A study was conducted to find an effective management strategy against RKN in guava at MITCAT guava orchard. Random sampling was carried out in the MITCAT Farm orchard and the nematode was identified as Meloidogyne enterolobii and the infestation was found to be above the Economic Threshold Level (> 2 J2s/g of soil). For the management of this nematode, an in vitro study was carried out using plant extracts and plant extracts with cow urine as it contains antagonistic and nematicidal properties. Among all 11 treatments, Neem + Cow urine showed good efficacy followed by Calotropis + Cow urine which gave minimum egg hatching and maximum juvenile mortality. The best treatment was Neem + Cow urine along with chemical and biocontrol management methods were adopted in field study and standardized the effective management strategies. Six treatments were fixed including the control and healthy control and assessed the initial and final population before and after the treatment. Based on the experimental results, chemical treatment Nimitz showed better performance by reducing half of the nematode population, followed by Velum Prime. The biocontrol agent, Pochonia chlamydosporia, and Neem + Cow urine are on par with each other and exhibited less performance than the chemical nematicide. In conclusion, the application of Nimitz is recommended for the control of M. enterolobii when the infestation is above ETL and is also found to be cost-effective. Whereas either P. chlamydosporia or Neem + Cow urine can be recommended for cases below ETL.
PERCEPTION OF FARMERS REGARDING ODISHA MILLET MISSION IN KORAPUT DISTRICT OF ODISHA
The study was undertaken in Koraput district of Odisha, India in 2022 with the aim to assess the perception of the tribal farmers regarding Odisha Millet Mission (OMM). A purposive sampling method was used to select Koraput district as it is one of the first seven districts where the OMM was implemented. The study utilized a structured interview schedule to collect data from 120 respondents selected through random sampling from two blocks and four villages. The perception of farmers and beneficiaries regarding the Odisha Millet Mission (OMM) was assessed through four tables presenting the frequency and percentage of respondents' perceptions about the objectives, activities, approaches, and promotion of improved agronomic practices of OMM. Overall, farmers and beneficiaries had a positive perception of OMM, with the promotion of household-level consumption and improved availability of quality seeds being the most highly ranked objectives and activities, respectively. These results suggest that OMM is seen as a positive initiative to promote millet cultivation and improve income and food security in Odisha.
Nitrogen driven microbial decomposition of in-situ rice residue impacts the meteorological parameters and productivity of happy seeder sown wheat in sub tropical India
The field experiment was conducted at Punjab Agricultural University, Ludhiana and University Seed Farm, Ladhowal, Punjab during rabi season of 2017-18 and 2018-19 with an aim to increase the pace of in-situ microbial decomposition of rice residues and stubbles using preplant dual sprays of two microbial cultures (Delftia or Aspergillus sp.) on happy seeder sown wheat. The experiment consisted of six nitrogen management techniques (kg/ha) in main plots and three microbial applications + an unsprayed control in sub plots and combinations of these were tested in split plot design with three replications. The meteorological indices viz., grain yield heat use efficiency (GY-HUE) and grain yield helio thermal use efficiency (GY-HTUE) were found to be maximum in N5 where nitrogen (N) was applied @ 150 kg/ha preceded by 3% urea spray on in-situ rice residue after paddy harvest. Maximum GY-HUE and GY-HTUE recorded in Delftia sp. i.e. M3. Minimum canopy temperature, maximum NDVI, 1000-grain weight and grain yield prevailed in N5 and M3 treatments. Treatment N5 produced 93.5% and 75.0% higher grain yield over control i.e. N1 at Ludhiana and 64.9% and 77.2% higher grain yield over N1 at Ladhowal during 1st year and 2nd year, respectively. Microbial culture in promoting rice residue decomposition and appropriate nitrogen application are crucial for wheat crop resilience and productivity in the face of changing climate scenarios.
Infrared thermography as a Potential Non-Invasive Tool for the assessment of skin surface temperature of buffalo heifers supplemented with cumin and molasses during hot dry and hot humid seasons under field conditions
This investigation was carried out in well adopted buffalo breed Murrah over a period of nine months, encompassing three seasons, to demonstrate the effect of cumin and molasses supplementation on thermographic profile of Murrah heifers at different anatomical locations viz., forehead temperature (°C), ear temperature (°C), elbow joint temperature (°C) and flank temperature (°C) during different season. A total of 24 Murrah heifers, maintained at Kathura village of Sonipat district (India) were selected and monitored for the thermal profiling at different anatomical locations of body using infrared thermography at monthly interval during hot dry and hot humid season using an IR camera (ThermaCamTM SC2000;FLIR Systems, Inc., Wilsonville, OR, USA). Thermograms were analysed by ThermaCamTM Researcher 2001 software (FLIR Systems AB, Danderyd, Sweden). Statistical analysis revealed that different supplement and seasons had significant (P<0.05) effect on body surface temperature at different anatomical sites. The magnitude of the increase in the IRT temperature at different anatomical regions of Murrah heifers was lower in the treatment groups compared to control group. The results of the study suggest that cumin and molasses can be used to alleviate heat stress in Murrah heifers.
CHARACTER ASSOCIATION AND PATH ANALYSIS STUDIES IN HIGH YIELDING MUTANTS OF POST RAINY SORGHUM (Sorghum bicolor (L.) Moench
The present investigation was undertaken at Department of Agricultural Botany, Vasantrao Naik Marathwada Krishi Vidyapeeth Parbhani. The experiment was carried out with the objective of estimation of correlation and path analysis. Initially, Parbhani Moti, the popular post rainysorghum variety, had been irradiated with gamma rays and ethyl methane sulphonate and their combinations at department of Agricultural Botany, VNMKV, Parbhani under a collaborative project with BARC, Mumbai. In M4 generation, 60 promising high yielding mutants derived from the above mutagenized population along with four checks were evaluated in eight environments. The pooled correlation revealed that, the grain yield per plant hadsignificant and positive correlation both at genotypic and phenotypic levels withplant height, stem girth, panicle length, panicle breadth, panicle weight, 1000grain weight, fodder yield per plant, biological yield per plant, harvest index. Onthe other hand, grain yield per plant had highly significant and negativecorrelation both at genotypic and phenotypic levels with days to 50 per cent flowering and internodal length. It indicates selection of these characters helps toenhance the yield.11. The grain yield per plant had non significant and positive correlation both at genotypic and phenotypic levels with days to maturity, leaf area, ironcontent, zinc content and non-significant negative correlation at genotypic andphenotypic levels with protein content.12. The path coefficient analysis revealed that, biological yield, and harvestindex at genotypic level while panicle weight, fodder yield and harvest index atphenotypic level exhibited high and positive direct effects on grain yield perplant. Thus, these characters turned-out to be the major components of grain yieldand direct selection for these traits will be rewarding for yield improvement.
