Introduction:
This is my Biology written project showcasing my Plan and Design lab and also the experiment made taken into practice. This project contains the actual PD lab, the results obtained, a graph showing the growth curve and photographs as proof of the experiment beingtruly practiced.
This written report is based on the topic Plant Growth and as well on the investigation in where plants grow best- black or red soil.

Soil:
Red soil:
Red soil, Any of a group of soils that develop in a warm, temperate, moist climate under deciduous or mixed forests and that have thin organic and organic-mineral layers overlying a yellowish-brown leached layer resting on anilluvial red layer. Red soils generally form from iron-rich sedimentary rock. They are usually poor growing soils, low in nutrients and humus and difficult to cultivate.

Black Soil:
Black soils are black in color and are also known as regur soils. Black soil is ideal for growing cotton and is also known as black cotton soil. It is believed that climatic conditions along with the parent rockmaterial are the important factors for the formation of black soil. The black soils are made up of extremely fine i.e. clayey material. They are well-known for their capacity to hold moisture. In addition, they are rich in soil nutrients, such as calcium carbonate, magnesium, potash and lime. These soils are generally poor in phosphoric contents. They develop deep cracks during hot weather, whichhelps in the proper aeration of the soil. These soils are sticky when wet and difficult to work on unless tilled immediately after the first shower or during the pre-monsoon period.

Plan and design Lab
OBSERVATION: In a vegetable garden the plants planted in black soil grew and developed better
and fasterthat those planted in red soil.
HYPOTHESIS: The okra seed (plant) will grow faster and better in black soil.
TOPIC: PLANT GROWTH
AIM: To plan and design an experiment to investigate if a okra seedling grow best in black soil.
MATERIAL/ APPARATUS: black soil ( 6 buckets)
red soil ( 6 buckets)
okra seed( 20 seeds)
water
bed(4 ft x 3ft)
Variables: Control
1. Amount of soil for each bed
2. Availability of water and sunlight
3. Number and type of seed planted
Manipulated
1. Type of soil( black or red)
Responding
1. Number of leaves of plant
2. Height of pant
3. Development and growth of plant

PROCEDURES:
1. Obtain six buckets of red and six buckets of black soil. As well, 20 okraseeds.
2. Make a bed frame on the ground four feet long by three feet wide (4 ft x 3ft).
3. Place six buckets or red soil on half of the bed and the other six buckets of black soil on the other half
4. Spread evenly the soil in its corresponding half only.
5. Carefully water the black soil with half a bucket of water.
6. Repeat procedure 5 with the red soil.
7. Make fiveholes six inches (6’’) apart from each other on both sides of the bed.
8. In each hole place two okra seeds and gently cover the holes without pressing on the soil hard.
9. After planting the seed, every two days go and collect observations. Report all observations on the seed or plants in the table below.
10. Water the soil two times per day with half a bucket of water for each type...
