ABSTRACT: Background: Taro (Colocasia esculenta) is a vital crop in tropical regions, but its growth is threatened by salinity, which limits productivity through osmotic stress and ion toxicity. This study evaluates the impact of salt stress on the 'Maruja' taro variety to assess its potential tolerance to saline conditions. Materials and Methods: A greenhouse experiment was conducted at the University of the Pacific, Colombia. Taro plantlets were grown in a soil-sand......

Keywords: Salinity stress, osmotic stress, tuber crop, plant physiology, chlorophyll content, electrolyte leakage

ABSTRACT: A field trial was conducted at the National Root Crop Research Institute, Umudike during 2015 and 2016 cropping seasons to evaluate the impact of crop spacing and weed control methods on the emergence pattern and density of Mimosa in cassava fields. The study site was predominately infested with M. invisa Mart. The trial was laid out in split-split plot in randomized complete block design with three replications. The main plot treatments were three crop spacing; 1 m × 0.6 m, 1 m × 0.8 m, and 1 m x 1 m. The sub-plot treatments were two cassava varieties of contrasting morphology (TME 419 and NR 8082) while the sub-sub-plot treatments were four weed control methods......

ABSTRACT: One of the factors influencing the farming of aquatic species is stocking density, which is directly related to organism growth. For this reason, the present study evaluated, via two experimental tests, different stocking densities in Macrobrachium acanthurus cultures undertaken in biofloc systems. The first test evaluated four densities (60, 120, 180, and 240 Ind/m3) for 14 weeks, while the second evaluated two densities (120 and 240 Ind/m3) for an eight-week culture period. The best results for the first test were obtained at densities of 60 Ind/m3, finding weight gain of 0.159±0.002 g, a growth rate of 638.6±11.54 %, a specific growth rate of 2.04±0.01% day-1, and a survival rate of 90.47±4.12 %.......

Keywords: Density, biofloc, production parameters, growth rate.

ABSTRACT: Maize (Zea mays L.) production is influenced by several factors including Nitrogen (N) fertilizer use, planting density, and soil pH. However, the excessive application of N beyond crop requirements by farmers in China has led to low yield limitation, reduced N use efficiency. To better understand these problems, we explored the differences in maize nitrogen management in China, this study uses a two-season field experiment was conducted to test the effect of nitrogen rate on maize growth, yield.......

ABSTRACT: The present study was initiated to quantitatively document their indigenous knowledge on the utilization of most common medicinal plants for livestock treatment respiratory. Since many small scale and resource-poor livestock farmers cannot afford synthetic pharmaceutical drugs, they turn to indigenous knowledge as an alternative key to unlock the power of ethnoveterinary medicinal plants to treat animal diseases. However, there is no ethnoveterinary pharmacopeia and data on ethnoveterinary usage of plants are still sparse. In this study, an ethnobotanical survey......
