The activity was proposed with the objective of determining the combined application rate of inorganic NPSB and N fertilizer that maximizes the yield and yield components of sweet potato. Sweet Potato variety Naspot-13, was used for the experiment. The experiment was arranged in factorial combination of four level of NPSB (0, 50, 100 and 150 kg ha-1) with four level of N2 (0, 23, 46 and 69 kg ha-1) in RCBD with 3 replications. The analysis of variance showed that the combination of 100 kg ha-...
Abstract: The climate change, water shortage and increasing evapotranspiration highlights the need to introduce water saving technologies for agricultural sustainability and crop production with a minimum input of water, mainly in semi-arid region. This experiment was conducted at Werer, Middle Awash Valley during the dry season of 2017/2018 to investigate the effects of mulching materials and furrow irrigation techniques on maize yield and water productivity under semiarid conditions. Split...
Abstract: The objective of this study was to evaluate the efficacy of the pesticides commonly used by farmers in controlling the Tobacco spider mite Tetranychus evansi Baker & Pritchard. Laboratory and greenhouse experiments were carried out to determine the susceptibility of T. evansi to dicofol, bifenthrin, propargite, lambda-cyhalothrin, dimethoate and profenofos+cypermethrin using the manufacturer’s recommended rates. Ovicidal and adulticidal (contact and residual) assays were done in ...
Early sprouting of yam tuber is a typical problem during storage resulting into weight losses, deterioration, shrinkage and reduction in quality. This work therefore applied vibration technique for the control of physical properties of yam sprouts (Dioscorea spp.) during storage in FUNAAB, Nigeria Environment. The physical properties (length, number, and weight of yam sprout, number of leaves, weight of roots) of the yam sprouts were determined for one hundred and forty white yam tubers....
Barley is one of the popular crops cultivated since ancient time in the world. Barley is one of the main cereal cropsproduced in the World and it is one of the most ancient crops among cereals and has played a significant role in the developmentof agriculture in the world. It is commonly used for food, animal feed and beverage value. The most important factors that reduceyield of barley is poor soil fertility, blanket recommendation of fertilizers, soil acidity (low soil pH), diseases and ins...
Faba bean (Vicia faba L.) is economically an important crop in Ethiopia. The productivity of Faba beanin Ethiopia has been declined due to poor management practices of inappropriate fertilizer rate and Bio fertilizerrates usage. Factorial combination of five rates of Blended fertilizer (0, 60, 121, 180 and 240 kgha-1 NPSZnB) andthree rates of Bio fertilizer (0,500 and 750 gha-1) treatments were laid out in RCBD with three replications. Days to50% flowering, days to 90% physiological maturity,...
ABSTRACT Two experiments were carried out at two locations (Ellkandi and Essuki area) for two consecutive seasons 2013 and 2014, to estimate the genetic variability among 15 sunflower hybrids, characters correlations with seed yield (t/ha) and to determine the genotype x environment interaction as well as to evaluate the stability of performance for the hybrids at the four environments. A randomized complete block design with four replications was used at each environment and data on 11 ...
These studies were conducted in White Nile State on one of the important field pests of tomato, African bollworm Helicoverpa armigera Hubner. The studies included a field survey to determine the presence and distribution of African bollworm in the White Nile State and a laboratory studies to calculate morphmetrics measurement s of insect stages , to study some biological activities of the insect and to evaluate the efficacy of leaves and stem ethanol and aqueous extracts of Lantana c...
ABSTRACT Drought is the major abiotic factor limiting crop production worldwide. Sorghum is one of the most drought tolerant grain crops that have the ability of addressing food insecurity in semi-arid areas. However, it is exposed recurrently to severe forms of drought and therefore, requires improvement to cope with moisture stress. The present investigation was undertaken to improve local sorghum varieties for drought tolerance in Burkina Faso. A participatory Rural Appraisal was cond...
To promote the organic cultivation of vegetable crops the department of agriculture and government of Kerala have been supporting several large and small scale schemes in varying localities in the state. In 2014 the department financially supported The Western India plywoods Ltd under this scheme for an organic vegetable cultivation programme. As part of this scheme studies were undertaken to assess the impact of vermicompost produced from wood waste on growth enhancement and productivity...
This short note is the first report on the use of Deproteinized leaf juice(DPJ) as a component of plant tissue culture medium. DPJ is the fraction of the juice extracted from crops that remains after the precipitation of Leaf Protein Concentrate(LPC). It is rich in non-protein nitrogen, total carbohydrates and some unidentified growth factors. In one of our experiments the shoot tips of cowpea and greenpea cultured on a minimal medium with DPJ, showed in vitro rooting from the cut portions in...
Hydroponics or the soilless cultivation is a popular and fast growing sector of agriculture and it has many advantages over soil-based system. It offers opportunities to provide optimal conditions for plant growth and therefore higher yields can be obtained compared to open field cultivation. In the aggregate system of hydroponics, different substrates are currently being used as support to the root system of plants under soilless cultivation. Substrates can be organic such as peat, pine bark...
Microgreens are edible baby plants with huge potential for leafy vegetable production and many consider this plant-based functional food as the new “Superfood”. Microgreens have many advantages over sprouts and they help to improve the nutritional value of our diet, with their high content of healthy compounds. During the microgreen cultivation, seeding is usually done as a broadcast or in rows and as the seeding density is difficult to recommend, most growers prefer to seed as thickly as...
Primary cultures were established with nodal segments from juvenile shoots of two-year old Paulownia fortuneii trees from a clonal plantation in Andhra Pradesh.A medium containing half-strength MS salts plus BAP(1 mgL) plus sucrose (2%) produced optimum bud break in the nodal explants
ABSTRACT This experiment was conducted at the Teaching and Research Farm of Federal University of Technology Akure, to determine influence of variety, stem age and portion on growth and stem yield of cassava. The experiment was a 3 by 2 by 3 factorial in a Randomized Complete Block Design with three replications. Stems of three different ages (12 months, 9 months and 6 months) of two portions (hard wood and semi-hard wood) from the three varieties (TMEB419, TMEB693 and I011371) were used...
