Role of Fertilizers in Agriculture

Sustainable agriculture is the farmers’ ability for producing food without affecting the environment as well as the surrounding ecosystem. There are a few issues which are connected to agriculture and one of them is the biophysical issue. I is linked with activities like fertilizer usage use of artificial nutrients and crop rotation along with the availability of resources like sunlight, water and wind.
While all these factors are equally important for plant growth, fertilizers are given extra importance, as they are the ones that help plants in the initial stages o growth. Fertilizers are materials of synthetic or natural origin which are applied to the plant tissues or soil for supplying plant nutrients crucial to plant growth. Fertilizers are meant for enhancing plant growth. The objective is met in 2 different ways:
1. Additives for providing nutrients,
2. And fertilizers for enhancing soil’s effectiveness by modifying aeration and water retention.
When it comes to fertilizers, Nitrogen, Potassium and Phosphorus are the 3 main elements or macronutrients. Nitrogen help in leaf growth, whereas potassium aids sturdy stem growth, water movement and promotion of fruiting and flowering. The nutrients needed for healthy growth of plants are classified based on the elements.
Fertilizers are applied to plants both as liquids and solids. Almost ninety percent of fertilizers are used as solids that are typically powdered or granulated. Liquid fertilizers consist of anhydrous ammonia, aqueous ammonium nitrate solutions or urea and so on. Such concentrated products can be diluted using water for forming concentrated liquid fertilizers. Also, liquid fertilizers have advantages like easier coverage and rapid effects. To be successful in agriculture, people need to know the basics of different fertilizers and their usage.

BROWN LEAF SPOT OF RICE

Cochliobolus miyabeanus (formerly known as Helminthosporium oryzae) is a fungus that causes brown spot disease in rice. This disease was the causal agent of the Bengal famine of 1943. Local name: Kandu, Chukke, Roga Period of occurrence: Seedling to maturity Extent of yield loss: 50-90% in extreme cases Mode of transmission/ dissemination: wind Sources of inoculum: Seed, Collateral hosts, Rice straw or Stubble Hosts and symptoms  Brown spot of rice is a plant fungal disease that usually occurs on the host leaves and glume, as well as seedlings, sheaths, stems and grains of adult host plants. Hosts include Oryzae sativa (Asian rice), Leersia (Cutgrass), Zizania (Wild rice), and other species as well such as Echinochloa colona (junglerice) and Zea mays (maize). Cochliobolus miyabeanus may cause a wide range of symptoms. General symptoms occurring on the hosts can be observed on many parts of the plant, including leaves, seeds, stems and inflorescences, along with the pres...

Advantages of Technology in agriculture

                                                                                Advantages of technology in agriculture include expediting crop production rate and crop quantity, which in turn reduces costs of production for farmers and food costs for consumers, and even makes crops more nutritious and livestock bigger and meatier. Technology in agriculture produces benefits for small-scale farms and national farming operations alike. These technologies include using environmentally sound and sustainable farming methods, such as no-till agriculture, and sophisticated equipment, including biotechnology. Biotechnology serves as an evaluative and forecasting tool, helping farmers address issues like poor soil conditions, lower crop output and low nutritional value. Biotechnology lets humans...

How to control maize disease using actellic

How to control  maize disease  using actellic (primophos methyl) 2 percent dust for proper protection against damage. 1. One and half large match-box full of acetilic dust and should be measured. 2. The walls and floor of rumbu or granary must be cleaned thoroughly. 3. About 22.73 kg of threshed grains equivalent of cobs should be spread in the store 4. The dust should be sprinkled evenly over the cobs in store 5.Another layer of cobs should be added to give 22.73kg of threshed grains and this should be repeated until all maize is treated and the store is full 6. Then the store for granary should be tightly closed OLE MOSES OKPAYI MATRIC NUMBER: AEC/15/1384
