Compatibility of Streptomyces sp., Metarhizium anisopliae, and Neem Seed Powder against Pigeon Pea Pod Borer Complex

Authors: Agale SV, Gopalakrishnan S, Gupta R, Rangarao GV, Srinivas V and Wani SP

Published: 2018, International Journal of Current Microbiology and Applied Sciences, 7 (2). pp. 390-397. ISSN 2319-7706

Abstract: Biopesticides such as Streptomyces sp. SAI-25, Metarhizium anisopliae and neem seed powder were previously demonstrated to have biocontrol potential against Helicoverpa armigera, the polyphagous insect pest of many crops. In the present investigation, the biopesticides, Streptomyces sp. SAI-25, Metarhizium anisopliae, and neem seed powder, were evaluated for their compatibility so that these can be used as consortia to manage pod borer complex. The results reveal that all the three biopesticides were compatible with each other and hence can be used in consortia to manage H. armigera.

Mass Production of Entomopathogenic Fungi (Metarhizium anisopliae) using Different Grains as a Substrate

Authors:  Agale SV, Gopalakrishnan S, Ambhure KG, Chandravanshi H, Gupta R and Wani SP

Published: 2018, International Journal of Current Microbiology and Applied Sciences, 7 (1). pp. 2227-2232. ISSN 23197692

Abstract: Investigations were carried out towards the “Mass production of entomopathogenic fungi (Metarhizium anisopliae) using different grains as a substrate” at ICRISAT, Patancheru, Hyderabad during 2016-17. For accomplishment of microbial control of insect pests, and successful mass production of the microbial agents in the laboratory, significant availability of the pathogen is a primary requirement in the biocontrol program. Metarhizium anisopliae is an entomopathogenic fungus which is used against a number of insect pests’ management and in very successful biopesticides in integrated pest management practices to reduces the cost of production and minimize the environment and public health hazard. To develop a proficient method for the deployment of this fungus as a bio control agent, various grains and liquid media such as Potato Dextrose Broth and Sabouraud’s Dextrose Broth were screened.

Utilizing Process-Based Modeling to Assess the Impact of Climate Change on Crop Yields and Adaptation Options in the Niger River Basin, West Africa

Authors:  Akumaga U, Tarhule A, Piani C, Traore B and Yusuf A

Published: 2018, Agronomy, 8(2) (11). pp. 1-23. ISSN 2073-4395

Abstract: Climate change is estimated to substantially reduce crop yields in Sub-Saharan West Africa by 2050. Yet, a limited number of studies also suggest that several adaptation measures may mitigate the effects of climate change induced yield loss. In this paper, we used AquaCrop, a process-based model developed by the FAO (The Food and Agriculture Organization, Rome, Italy), to quantify the risk of climate change on several key cereal crops in the Niger Basin. The crops analyzed include maize, millet, and sorghum under rain fed cultivation systems in various agro-ecological zones within the Niger Basin. We also investigated several adaptation strategies, including changes in the sowing dates, soil nutrient status, and cultivar.

Key and Smart Actions to Alleviate Hunger and Poverty Through Irrigation and Drainage

Authors:  Unver O, Wahaj R, Lorenzon E, Mohammadi K, Osias JR, Reinders F, Wani SP, Chuchra J, Lee P and Sangjun IM

Published: 2018, Irrigation and Drainage, 67 (1). pp. 60-71. ISSN 15310353

Abstract: In the pursuit of information to support policies and actions to alleviate hunger and poverty through irrigation and drainage, this paper attempts to provide correlations between water scarcity, communities and poverty. Many reviews have found strong direct and indirect relationships between irrigation and poverty. One of the main goals of the international community is to eliminate hunger and poverty and in this perspective, through the Millennium Development Goals, much progress has been achieved and evidence obtained. Sustainable Development Goals and various other United Nations initiatives intend to move forward this agenda by making it a part of broader development frameworks. In this paper, the important elements of irrigation and drainage that affect the alleviation of hunger and poverty are discussed.

The climate-smart village approach: framework of an integrative strategy for scaling up adaptation options in agriculture

Authors:  Aggarwal PK, Jarvis A, Campbell BM, Zougmore RB, Khatri-Chhetri A, Vermeulen SJ, Loboguerrero AM, Sebastian LS, Kinyangi J, Bonilla-Findji O, Radeny M, Recha J, Martinez-Baron D, Ramirez-Villegas J, Huyer S, Thornton P, Wollenberg E, Hansen J, Alvarez-Toro P, Aguilar-Ariza A, Arango-Londoño D, Patiño-Bravo V, Rivera O, Ouedraogo M and Yen BT

Published: 2018, Ecology and Society, 23 (1) (14). pp. 1-15. ISSN 1708-3087

Abstract: Increasing weather risks threaten agricultural production systems and food security across the world. Maintaining agricultural growth while minimizing climate shocks is crucial to building a resilient food production system and meeting developmental goals in vulnerable countries. Experts have proposed several technological, institutional, and policy interventions to help farmers adapt to current and future weather variability and to mitigate greenhouse gas (GHG) emissions. This paper presents the climate-smart village (CSV) approach as a means of performing agricultural research for development that robustly tests technological and institutional options for dealing with climatic variability and climate change in agriculture using participatory methods. It aims to scale up and scale out the appropriate options and draw out lessons for policy makers from local to global levels.

Proteome analysis of Aspergillus flavus isolate-specific responses to oxidative stress in relationship to aflatoxin production capability

Authors:  Fountain JC, Koh J, Yang L, Pandey MK, Nayak SN, Bajaj P, Zhuang WJ, Chen ZY, Kemerait RC, Lee RD, Chen S, Varshney RK and Guo B

Published: 2018, Scientific Reports, 8 (1) (3430). pp. 1-14. ISSN 2045-2322

Abstract: Aspergillus flavus is an opportunistic pathogen of plants such as maize and peanut under conducive conditions such as drought stress resulting in significant aflatoxin production. Drought-associated oxidative stress also exacerbates aflatoxin production by A. flavus. The objectives of this study were to use proteomics to provide insights into the pathogen responses to H2O2-derived oxidative stress, and to identify potential biomarkers and targets for host resistance breeding.

Mixed-species allometric equations and estimation of aboveground biomass and carbon stocks in restoring degraded landscape in northern Ethiopia

Authors:  Mokria M, Mekuria W, Gebrekirstos A, Aynekulu E, Belay B, Gashaw T and Brauning A

Published: 2018, Environmental Research Letters, 13 (2). pp. 1-15. ISSN 1748-9326

Abstract: Accurate biomass estimation is critical to quantify the changes in biomass and carbon stocks following the restoration of degraded landscapes. However, there is lack of site-specific allometric equations for the estimation of aboveground biomass (AGB), which consequently limits our understanding of the contributions of restoration efforts in mitigating climate change. This study was conducted in northwestern Ethiopia to develop a multi-species allometric equation and investigate the spatial and temporal variation of C-stocks following the restoration of degraded landscapes. We harvested and weighed 84 trees from eleven dominant species from six grazing exclosures and adjacent communal grazing land.

Investigation of gene action for resistance to early leaf spot of groundnut

Authors:  Tembo E, Charlie H and Tembo L

Published: 2018, International Journal of Agriculture, Environment and Bioresearch, 3 (1). pp. 21-29. ISSN 2456-8643

Abstract: Groundnut (Arachis hypogaea L.) is an important global oilseed crop and a major source of protein and vitamins in many rural areas of Africa. In Zambia, the production of groundnut is limited by several factors, among which Early Leaf Spot (ELS) caused by Cercospora arachidicola Hori, is a major destructive disease. Development of resistant varieties to ELS remains the most viable disease management strategy. The objective of this study was to investigate the type of gene action conditioning resistance to C. arachidicola in order to generate information for breeding of ELS resistant groundnut varieties in Zambia. The field work was conducted at Chitedze Research Station in Malawi which is a known hot spot for groundnut foliar diseases.

Expression of Tolerance to Pod Borer, Helicoverpa armigera (Lepidoptera: Noctuidae) in Relation to Biochemical Content of Chickpea Leaves

Authors:  Bangar SS, Bangar HA, Dudhare MS, Gahukar SJ, Wadaskar RM, Akhare AA and Sharma HC

Published: 2018, International Journal of Current Microbiology and Applied Sciences, 6. pp. 223-229. ISSN 2319-7

Abstract: The pod borer (Helicoverpa armigera) is one of the most serious pest of chickpea and plant resistance is an important component for managing this pest. To develop cultivars with resistance to insects, it is important to understand the role of different components associated with resistance to insects. Therefore, in this study we characterized RIL’s (recombinant inbred lines) population for total phenol content leaves and organic acid profiles in the leaf exudates which are associated with tolerance to H. armigera.
