Interactive Effect of potential biocontrol agents and organic amendments on lentil wilt pathogen incited by Fusarium oxysporum f. sp. lentis and its management
Lentil (Lens culinaris Medik), is widely grown pulse crop. Lentil crop might be attacked by several seed and soil borne diseases. In vitro bio-efficacy of different antagonists and organic amendments on mycelial growth of Fusarium oxysporum f. sp. lentis by using seven Trichoderma spp. (T. harzianum, T. viride, T. hamatum, T. asperellum, T. virens, T. koningii, T. atroviride) and seven OAs (vermicompost, FYM, mustard cake, goat cake, mungbean chickpea, cluster bean). In vivo estimation of microflora propagules density, growth, phenological, physiological (chlorophyll and carotenoid contents) biomass parameters and qualitative, yield contributing characters. Under in vitro, the highest mycelial growth inhibition (68.52%) was found with T. harzianum, and among OAs maximum mycelium inhibition was recorded with vermicompost (63.34%). In vivo study, T harzianum + vermicompost effectively reduces microflora propagules (23, 42, 45, 40×105cfu/g soil) at the different intervals (planting, 1, 2, 3, 3.5 months) than the other treatments. This combination enhances percent germination (96.67), phenological and biomass parameters like plant height (47.23 cm), pods/plant (60.42), seeds/plant and yield of seed/plant (4.45 g), fresh and dry weight of shoot & root (33.98, 2.89 and 6.97, 0.79 g) and reduces the disease incidence (14.88 %). Physiological pigments viz; chlorophyll (3.75 mg/ml) and carotenoids (0.71 mg/ml) also recorded maximum in T harzianum + vermicompost combination. The qualitative parameters like plant height (44.67 cm), root nodule (95.00), and yield contributing characters like pods/plant (59.00), seeds/plant (100.00), yield (430.00 kg/h) found maximum in this combination.
Design Optimization of a Coconut Climbing Mechanism
A coconut climber was subjected to Finite Element Analysis (FEA) to have an optimized design. Using density-based topology optimization, the coconut climber was redesigned to improve its strength properties and reduce its overall weight. The proposed alternative design has a minimum yielding factor of safety of 5.70 and a weight reduction of at least 30.93%. Aluminum and carbon fiber were also proposed as alternatives to steel. Using these alternatives, the weight of the new design can be further reduced to at least 75.47% (for aluminum) and 84.06% (for carbon fiber) without compromising its strength properties. The numerical results revealed that the proposed design enhanced the overall functional attributes of the climber. It is recommended that other topologies and materials should be explored to further improve the design of the coconut climber.
Utilization of water stressed conditions: Commercial bio-molecules from agricultural crop and their scope for boosting income of water stress areas
The world has approximately 90 per cent of its area under rainfed conditions and the dry spells are the characteristics feature of this area which push crop towards water stress. Climate change scenarios predict extended periods of drought and this has emphasized that now we look towards the possibility of positive utilization water stress. However, no one review till date has published that focused on ways of positive utilization of water stress. This review focuses on such intensity and time of occurrence of stress in which a crop is benefited. The crop facing water stress have several changes at morphological and biochemical levels, and these changes not always be deleterious for crop. Fortunately, earlier literature showed that there are many positive effect associated with water stress. For instant trans-generational effects (parent crop during grain formation imposed to water stress and the seeds obtained from them have potential to withstand drought), increase in secondary metabolites, thereby potentially increasing plant defenses and the concentrations of compounds involved in plant quality, particularly taste and health benefits, increase in oil, fiber and protein content etc. Moreover, water stressed produced secondary metabolites has high marketing values (i.e. commercial bio-molecules). However, these positive effects are highly dependent on the degree and time of occurrence of water stress. This review also discusses degree and time of occurrence of water stress with corresponds to positive effects.
Performance of Lentil (Lens Culinaris) Varieties under Rice-Lentil Cropping System in Eastern Part of India
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
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.
