Precision agriculture is the developing trend of modern agriculture, and the rational utilization of fertilizer is one of the key technologies in the precision agriculture, which needs to fertilize variably according to the crop needs and soil fertility conditions. Thus a fertilizer automated proportioning equipment is developed to Proportion the three fertilizers: Nitrogen fertilizer, Phosphor...

Just after transplanting, the vegetable has difficulty in nutrients uptake. To explore the effect of different fertilization on spring cabbage (Brassica oleracea L. var. capitata) production and fertilizer use efficiencies, this experiment consisting of six treatments was implemented and divided into three groups: 1) no fertilizer (NF) and vegetable planting fertilizer (VPF); 2) conventional fe...

The inherent problems associated with inorganic fertilizer such as scarcity and high cost informed the invention of cocoa pod husk based organic fertilizer. The impact of the fertilizer on cocoa output is hereby investigated in this study. The study was conducted in Cross-River State, Nigeria and purposive random sampling technique was used to select fifty cocoa farmers including the user and n...

Soil physicochemical properties, soil microbial biomass and bacterial community structures in a rice-wheat cropping system subjected to different fertilizer regimes were investigated in two seasons (June and October). All fertilizer regimes increased the soil microbial biomass carbon and nitrogen. Both fertilizer regime and time had a significant effect on soil physicochemical properties and ba...

Rice (Oryza sativa L.) grown on a clay soil in a direct-seeded, delayed-flood system as used in the southern U.S. requires 30 to 60 lb/acre more nitrogen (N) fertilizer to achieve maximal grain yields compared to rice grown on silt loam soils. Seasonal N fertilizer accumulation studies are almost non-existent for rice grown on clay soils. Therefore, a two-year field study was conducted to evalu...

This experiment was aimed to study the effect of interaction herbicides and varieties with different types foliar nutrition in production highest yield for three wheat varieties. A field carried out at College Agricultural Engineering Sciences - University Baghdad / Jadiriyah two seasons, as seeds first season were sown on 13/12/2018 harvested 15/5/2019, second 4/12/2019 10/5/2020. The randomiz...

Abstract In the spring of 2022, researchers from University Mosul’s Faculty Agriculture and Forestry conducted an experiment on a vegetable field. this experiment, we looked at three variables: first, effects two different potato cultivars (Montreal EL-Beida). For second part, soaked potatoes in solution potassium humate with concentration (0, 0.5, 1 g L -1 ). Therefore, had 18 treatments (2 3 ...

Nano cattle bone ash can reduce requirement for SP-36 and increase pod yield. This study aimed to examine the physiological response, growth, yield of edamame soybean in entisol concentration frequency foliar application nano fertilizer.The research was conducted an experimental method which arranged a Randomized Completely Block Design (RCBD) consists factor (0.15, 0.30, 0.45%) (2, 3, 4 times)...
