Therapeutic and nutritive uses of <i>Macrotyloma uniflorum</i> (Lam.) Verdc. (Horsegram), a somewhat neglected plant of the family Fabaceae

Natural Resources for Human Health (2023)

S. N. Sah Supriya Kumari Sharma Afroz Alam Prachi Baliyan

Underutilized legumes are a significant group of crops that have particular importance in subsistence farming and the nutritional security of resource-poor communities in developing countries. Horsegram [<i>Macrotyloma uniflorum</i> (Lam.) Verdc.], a lesser-known neglected legume, is one such crop that is mainly cultivated in Asian and African countries as a dual-purpose crop. This climate-resilient legume is well-known for its drought hardiness and favorable agronomic features that make it suitable for cultivating dry lands under poor soil fertility conditions. It has a nutritional value comparable to other commonly consumed pulses and serves as a cheap source of nutrition for unprivileged rural communities residing in inaccessible areas. In addition, horsegram has excellent therapeutic properties and is traditionally used to cure various conditions such as kidney stones, asthma, bronchitis, leukoderma, urinary discharges, heart diseases, and piles. Furthermore, it possesses anti-diabetic and anti-ulcer activity and can help in the dietary management of obesity due to the presence of beneficial bioactive compounds. This review summarizes the nutritional composition, antinutritional factors, medicinal properties, and the potential for horsegram to be exploited as functional/medicinal food for health benefits.

Design, Fabrication and Testing of Parabolic Dish Solar Concentrator

S. N. Sah Nishant Oli Shishir Chhetri Sagar Gyawali Gambir Shrestha

The Parabolic Dish Solar Concentrator (PDSC) plays a vital role in harnessing solar energy efficiently. Harnessing solar energy effectively is crucial in the quest for sustainable energy solutions, and the Parabolic Dish Solar Concentrator stands out as a promising and simple technology in this regard. The parabolic dish solar concentrator, with a 1.84-meter aperture diameter, 0.342-meter depth, and 0.619-meter focal length, was designed, fabricated, and tested. Using a concentrating reflector, heat from the sun is focused on a receiver. The main objective of the project is to design, fabricate, and test the Parabolic Dish Solar Concentrator. At the focal point, the collected energy is used for heating water and cooking rice, eggs, and potatoes in the receiver. The receiver arrangement is supported by a four-bar mechanism, ensuring that the sun's rays are always directed toward the receiver at different times of the day. On a sunny, cloud-free day, the maximum temperature recorded was 370°C. The water heating thermal efficiency obtained was 24.67%. The cooking time varies due to the intensity of solar radiation and the time of day. It was observed that during mid-day, the cooking time was shorter because of the higher intensity of solar radiation.

Adapting Rice Technologies to Climate Change

Hydro Nepal Journal of Water Energy and Environment (2012)

B.P. Tripathi Ranjit Mahato Ram Baran Yadaw S. N. Sah Bishnu Bilas Adhikari

Rice is prime crop that contributes to food security and provides employment to a large number of populations in Nepal. More than 51% of the area of rice land in Nepal is rain-fed. Over the last few years, however, the country has been experiencing erratic rainfall, with less water available for rice cultivation, as well as temperature rise. There are both submergence (flooding) problems and drought in the main rice growing areas. Hence, there is a need to generate suitable rice technologies under such adverse conditions.The International Rice Research Institute (IRRI) has initiated research in collaboration with the Nepal Agricultural Research Council (NARC) and the Institute of Agriculture and Animal Sciences (IAAS) to develop suitable rice technologies for submergence and drought prone areas of Nepal. Various rice germplasm was brought from IRRI, Philippines, and research was conducted at NARC and IAAS as well as in farmers’ fields following a program of Participatory Varietal Selection (PVS). Water-saving rice technologies as well as other technologies, including indigenous practices, were identified for utilizing less water for rice cultivation. Several varieties of rice under drought prone and under submergence conditions were identified, and have been recommended for cultivation by Nepalese farmers.DOI: http://dx.doi.org/10.3126/hn.v11i1.7209 Hydro Nepal Special Issue: Conference Proceedings 2012 pp.69-72

Evaluation of Quality Protein Maize (QPM) Genotypes under Rainfed Mid Hill Environments of Nepal

Nepal Journal of Science and Technology (1970)

Shesh Raman Upadhyay Dil Bahadur Gurung D. C. Paudel K. B. Koirala S. N. Sah

Maize (Zea mays L.) is the second most important staple food crop after rice and a major food crop of the resource poor people in the hills of Nepal. Prevailing normal maize (non-QPM) is deficient in two essential amino acids, lysine and tryptophan. The majority of hill farm families are suffering from protein malnutrition as their major diet is maize and cannot afford animal protein. QPM contains opaque-2, a single gene mutation that alters the protein composition of the endosperm portion and nearly double the essential amino acids concentrations than the normal maize grain. The biological value of protein in QPM maize is about 80%, that of milk is about 90% and in normal maize (non-QPM) is about 45% only. A series of experiments were conducted in RCB Design during 2004/2005 summer season and superior genotypes selected and promoted from Observation Nurseries to IYT and CVT (Coordinated Varietal Trial) respectively. CVTs were evaluated across mid-hills of Nepal. Based on four environmental mean results in CVT: the genotype S99TLWQ- HG-AB (QPM maize) produced the highest mean grain yield (4899 kg ha-1) followed by Population 44 C10 (4552 kg ha-1) and Manakamana-3 (4436 kg ha-1) respectively. However, most of the tested QPM genotypes were at par with improved check for grain yield production and significantly highest grain yielder than the farmres’ variety (local check). Concluding results revealed that the genotype S99 TLWQ-HG-AB performed very well across the mid hills. Findings of the present study will help to reduce protein malnutrition problem in the hills of Nepal.Key words: GGE-biplot; Genotype x environment interaction; Normal maize; Open pollinated varieties (OPV); Quality protein maize (QPM).DOI: 10.3126/njst.v10i0.2803Nepal Journal of Science and Technology Volume 10, 2009 December Page: 9-14
