Performance of Lentil (Lens Culinaris) Varieties under Rice-Lentil Cropping System in Eastern Part of India

Paper ID- AMA-09-02-2022-11113

Lentil is the second major Rabi sown legume after chickpea, which is grown in winter season. The productivity of lentil in India is 730 kg/ha and in Uttar Pradesh is 891 kg/ha. One of the major constraints in cultivation of existing lentil varieties is low productivity and poor management practices. It appears due to non-adoption of recommended high yielding varieties and advance technologies by the farming community in the Eastern Plains of Uttar Pradesh. Frontline demonstrations (FLDs) programme is an effective technology transfer tool for better technology adoption that bridges the yield gaps. The technological extension yield gaps in lentil were carried out for 3 years during 2013-14 to 2015–2016 under an FLD programme in rice-lentil cropping system in hot sub-humid (moist) ecoregion of India, revealing that due to technological extension yield gaps, there was a large yield gap between potential demonstration yields. To replace this anomalous, we had conducted 62 FLDs at farmer fields of various adopted villages by the Krishi Vigyan Kendra (KVK), Deoria under ICAR-Indian Institute of Vegetable Research, Varanasi, Uttar Pradesh. Cultivation practices comprised under FLD viz. improved varieties, irrigation, date of sowing, seed treatment, spacing, balance use of fertilizers, intercultural operations and plant protection measures showed increase in yield of lentil varieties from 10.18-35.57% over local checks. Technology gap was highest in HUL 57 (754 kg/ha) and lowest in L 4147 (520 kg/ha). The analysis of data for extension gap showed that L 4147had the highest gap (290 kg/ha) and Pusa L4076 had the lowest gap (110 kg/ha). Technology index was highest (41.8%) in HUL 57 and lowest (20.8 %) in L4147.The lower the value of the technology index indicates the more feasibly of the technology in Eastern Plains of Uttar Pradesh.

Validation of stable resistance in pearl millet hybrids to ergot disease caused by Claviceps fusiformis

Paper ID- AMA-08-02-2022-11111

Pearl millet (Pennisetum glaucum (L.) R. Br.) is a staple and nutritious food for billions of underprivileged people living in the semi-arid tropical provinces of Africa and Asia, though it is consumed round the globe as nutritious and gluten-free diet. The present investigation was conducted to validate and verify the existed stable resistance to ergot (Claviceps fusiformis) in 30 pearl millet hybrids and composites during Kharif 2020 and 2021. The result showed that thirty hybrids and composites of pearl millet were validated under artificially inoculated field conditions. Among these hybrids and composites, Nirmal- 4915, RHB-177, RHB-173, HHB-67, PH-86M84, Dhanskati, HHB-67 Improved and 86-M-01 were proved highly resistant to ergot disease in Rajasthan. In conclusion, these hybrids and composites can be used for successful cultivation of pearl millet as the most effective, economical and environmentally sustainable.

There is a paucity of information available on the practicality, suitability, and profitability of in vitro raised plants of clonal apple rootstocks as compared to field-multiplied plants through traditional methods. The present investigation was carried out at the Plant Tissue Culture laboratory of the School of Biotechnology (SBT) and the Tissue Culture laboratory of the Advanced Centre for Horticulture Research (ACHR), Udheywalla, SKUAST-Jammu, Main Campus, Chatha. Results indicated that the unit cost for in vitro raised plantlets from explants excised from a 2-3 year-old mother block of clonal apple rootstock MM 106 was estimated to be Rs. 44.56, which included Rs. 41.38 and Rs. 3.18 at the tissue culture production phase and greenhouse production phase, respectively, whereas, in MM 111 clonal rootstock, the unit cost for in vitro raised plantlets was estimated to be Rs. 36.95, which included Rs. 34.29 and Rs. Moreover, as per the general practices in the literature, the estimated production cost of an ex vitro seedling is Rs. 150.

Mechanism and Potential Role of Mycorrhizal Fungi as Biocontrol Agents

Paper ID- AMA-08-02-2022-11107

AM fungi establish a symbiotic relationship with most of the plant root systems, thereby forming a vital part of terrestrial ecosystems. It is unique association that play important role in nutrient exchange, increase the uptake of mineral nutrients from the soil through the external hyphal network (extra-radical hyphae) by solubilizing phosphate, nitrogen and other essential micro nutrients such as Ca, Cu, Mn and Zn. AM (fungi) association also improved soil structure, increase drought tolerance and enhanced beneficial harmone such phytoalexins, cellulose deposition, hydroxyproline-rich glycoproteins, phenolics, peroxidases, chitinases, β-1-3 glucanases and pathogenesis related proteins that leads to resistance against plant pathogens. These fungi have the antagonistic ability against plant pathogens and act as bio-stimulants and bio-protectors that ensure crop production and protection, reducing plant pathogenic population to safeguard sustainable farming without harming the environment. As biocontrol agents, mycorrhiza reduces the incidence and severity of several plant diseases caused by soil borne pathogens and nematode.

Investigation of three lateritic soils mixed with Geopolymer based Kaolin – Rice husk ash as road construction materials.

Paper ID- AMA-07-02-2022-11106

This paper explores the usage of two wastes (Portland cement powder (PCP) and rice husk ash (RHA) for improving the engineering strength of threesubgradelateritic soil gotten from where road failures are prominent in Nigeria. It displays an experimental perception on the stabilization of the soil with RHA+PCP-based geopolymer. In the RHA-PCP based geopolymer, the stabilizers were blended with the lateritic soil in varying quantities ranging from 2 to 10% for RHA-PCP stabilization. Subsequently, the optimum percentage of RHA-PCP was activated with sodium silicate. The results demonstrate improved mechanical with the two stabilizers. Conversely, the stabilization done with RHA at 10% and geopolymer (6% cement plus 6% RHA and 8% PCP) were the optimal. By and large, RHA stabilization behaved better than PCP geopolymer stabilization.
