Doses of the following organic substances were used in the experiment in five repetitions:
Organic mineral fertilizer, NPK fertilizer 02-20-10 + 25 percent chicken manure dose of 600 kg ha-1 at sowing
Organic fertilizer chicken manure dose of 2000 kg/ha at sowing
NPK 02-20-10 fertilizer at a dose of 800 kg/ha
To get more accurate and specific results, the researchers evaluated the following factors:
The height of plants at flowering stage and grain filling
The height of the first pod that grew
Number of produce
Thousand grain weight
The number of pods per plant
The number of seeds per pod
The results showed both the organic-mineral fertilizer and the organic fertilizer chicken manure positively affected plant growth. Moreover, they also helped increase the number of pods per plant, as well as produced pods that have two or three seeds inside.
Produce that grew on organic fertilizers contain zero toxins
Reduces the cost of maintaining the land
Reduces the need for expensive farm inputs
Promotes a safe and healthy environment
Production of organic fertilizers creates employment opportunities for many people
Meanwhile, chicken manure is not the only organic waste you can use as a natural fertilizer. There is often other unused organic materials lying around your farm, or even your home, which can be turned into an organic plant food.
Bone meal -- This is made from scrap bones from slaughterhouses, which are then finely ground to produce fertilizer. Bone meal contains high levels of calcium and has up to 15 percent phosphate. It's mostly used on flowers, bulbs, and fruit trees.
Blood meal -- This type of fertilizer is made from dried animal blood turned into powder. It is rich in nitrogen and is often used to promote green leafy growth.
Shellfish fertilizer -- Shellfish and crabs are crushed and processed to become fertilizer. It is also rich in protein and has a good amount of phosphate, making it ideal to boost flowering.
Seabird guano -- This is made from the accumulated excrement of seabirds. It contains high levels of nitrogen, phosphorous, potassium, and other trace elements. Seabird guano is often used to promote flowering and growth of strong root systems.
Rock phosphate -- This is sourced from finely ground lime-phosphate and has high concentrations of trace micronutrients, as well as over 30 percent phosphate. Farmers use it, given it remains in its original state until the plants absorb its nutrients.
