Suppressive effects of maize rhizospheric fungi on Rhizoctonia solani f. sp. sasakii inciting banded leaf and sheath blight

Paper ID- AMA-16-11-2023-12733

We employed the classical microbiological methodology to isolate endophytic fungi inhabiting the rhizosphere of maize (Zea mays L.). Identification of these endophytic fungi was carried out using ribosomal DNA sequencing, aiming to uncover distinct distribution patterns of these organisms that persist asymptomatically within the healthy root tissues of maize plants. The dominant fungal species associated with the roots of the maize hybrid PHM-1 were Aspergillus niger, Aspergillus terreus, Cladosporium cladosporidies, Penicillium oxalicum, and Penicillium raperi. To assess their potential impact, an in vitro assay was conducted to evaluate these isolates against Rhizoctonia solani f. sp. sasakii, the causal agent of banded leaf and sheath blight (BLSB). This disease is particularly prevalent in tropical regions worldwide and poses a significant threat to maize cultivation. Notably, the Aspergillus and Penicillium complexes found in the maize rhizosphere exhibited promising efficacy in inhibiting this soil-borne disease affecting maize plants.

Influence of anther pretreatment on the efficiency of haploid production in marigold (Tagetes erecta L.)

Paper ID- AMA-15-11-2023-12731

Varied types of pretreatments cause stress on microspore bearing anthers which induces change of the development pathway of microspore from gametophytic to sporophytic which in turn leads to the production of haploids. In our experiments different pretreatments were given to anthers of marigold before in vitro culturing of male gametophytes. Flower buds (of size 2-2.5cm) in which a majority of microspores had reached the mid- or late-uninucleate stage were tested with regard to the effect of cold pretreatment at 4°C for 3, 6, 9 and 12 days and starvation in 0.3 M mannitol solution for 2, 4, 6 and 8 days. Chilling at 4°C for 9 days resulted in highest percent of responding anthers (91.5%), highest percent caulogenesis (54.7), highest number of shoot buds per anther (7.2), highest number of regenerants per anther (5.5), lowest number of days taken for callusing (12.25) and lowest number of days taken to shoot bud induction (15.75). while starvation of anthers by using 0.3M mannitol solution for 4 days resulted in highest percent of responding anthers (81.75%), lowest number of days taken for callusing (11.75), highest percent caulogenesis (66.5%), lowest number of days taken to shoot bud induction (15.25), highest number of shoot buds per anther (7.25) and highest number of regenerants per anther (5.75). Among the two pre-treatments evaluated, cold pretreatment showed better results in terms of percent responding anthers while mannitol starvation was found best for percent caulogenesis.

Crop establishment method and weed management practice influences weed prevalences, crop growth and yield of maize in maize-wheat-greengram cropping system

Paper ID- AMA-15-11-2023-12726

Weeds are considered to be a major biotic constraints in crop production. Under conservation agriculture (CA), non-inversion of soil, retention of previous crop residues, and crop diversification alter the weed dynamics. Although, it supports sustainable crop production by enhancing soil health. Long-term adoption of CA may help in establishing perennial weeds. Therefore, a field experiment was carried out to assess the feasibility of crop establishment methods and weed management practices in maize during the rainy season of 2021 and 2022. The experiment was laid out in a split-plot design with three replications. The main plot comprised two crop establishment methods, conventional tillage (CT) and zero tillage (ZT) and four weed management practices [weedy check, recommended herbicide (RH), integrated weed management (IWM), herbicide rotations (HR)] in maize-wheat-greengram cropping system. The results revealed that ZT exhibited lower weed density (89.5 and 72.9 no. m-2, respectively) and biomass (62.6 and 42.9 g m-2, respectively). Among the weed management practices, HR recorded the lowest weed density (43.8 and 29.8 no. m-2, respectively) and weed biomass (34.1 and 19.4 g m-2, respectively). Lower weeds under ZT, encourages plant growth and it became (1.9 and 2.7%, respectively) taller and (22.2 and 18.9%) heavier over CT. Imposition of herbicides in rotation also provided good weed control, thus, obtained taller and heavier plants in both the years. The findings also showed a strong negative linear relationship between weeds and grain yield. Regression analysis between yield attributes and yield showed a positive linear relationship. Growing maize under ZT obtained higher grain and straw yield with 6673 kg ha-1 in 2021 and 5765 kg ha-1 in 2022, while straw yield was 11366 kg ha-1 and 9319 kg ha-1, respectively. Imposition of weed management with rotating herbicides exhibited significantly higher grain yield (7815 and 7031 kg ha-1, respectively) during both the years, however, straw yield was higher in HR (12163 kg ha-1) in the first year, and in the second year it was higher with IWM (10587 kg ha-1). Based on the experimental findings, maize can be grown under ZT with either HR or IWM for effective weed control, better crop growth, and higher yield in maize-wheat-greengram system.

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.

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.
