Technical efficiency and yield gap of smallholder wheat producers in Ethiopia: A Stochastic Frontier Analysis
Improving technical efficiency of smallholder farmers is one of the options to increase wheat yield in developing countries. This paper assesses technical efficiency, factors for inefficiency and the yield gap due to technical inefficiency in major wheat producing regions of Ethiopia, where the support to agricultural research for development of strategic crops (SARD-SC) wheat project has been implemented using primary...
Direct shoot regeneration from hypocotyl explants of Heracleum candicans Wall: A vulnerable high value medicinal herb of Kashmir Himalaya
Heracleum candicans belongs to the family Apiaceae, and is categorized as a vulnerable Himalayan medicinal herb. Due to its diverse chemical constituents it is having an increased demand in pharmaceutical industries, especially in international market. This herb is commercially useful as a major source of Xanthotoxin which is widely used to treat leucoderma and to prepare suntan lotions. During the present study direct...
Use of millimeter ruler as an alternative tool in the phenotyping of potential descriptors of soybean
The soybean stands out in the Brazilian agribusiness and part of this success stems from the development of improved cultivars. One of the requirements for the concession of protection to a given cultivar is that it should be distinct from others cultivars. Potential additional descriptors of soybean have been studied. Thus, the aim of this study was to evaluate the performance of the millimeter ruler in the measurement...
Screening for resistance to Striga gesnerioides and estimation of yield loss among Cowpea (Vigna unguiculata (L.) Walp.) progenies in the Upper East Region of Ghana
Parasitic weed Striga gesnerioides (Willd.) is one of the major constraints of cowpea production. Host-plant resistance seems to be efficient and economical in controlling the pest. The objectives of this study were to evaluate recombinant inbred lines developed between IT97K 499-35 (Striga resistant parent,) and Sanzi (susceptible parent), by Single Seed Descent (SSD), for Striga resistance in Northern Ghana. The study...
Cultivation of common bean with the application of biochar of ouricuri (Syagrus coronata (Mart) Becc.) endocarp
Biochar has attracted the attention of the scientific community due to its promising applicability and contribution to the elevation of soil chemical and biological aspects, directly influencing the microbiota, fertility levels and yield of agricultural crops. The objective of this study is to determine the chemical and biological attributes of an acrisol cultivated with beans and submitted to the application of...
Greenhouse gas emissions from an alkaline saline soil amended with urea: A laboratory study
Soil of the former lake Texcoco is nitrogen (N) depleted, so any attempt to vegetate the area will require the application of an N fertilizer. Urea is commonly used as fertilizer, but its application to soil might affect emissions of greenhouse gases (GHG), such as carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4), and the high pH and electrolytic conductivity (EC) in the Texcoco soil might inhibit the...
