design of experiments

the planning of an experiment so that the results will provide evidence to support, refute or modify the particular hypothesis which is being tested. For example, any experiment which involves sampling should be planned in such a way that the results are sufficient to allow proper statistical testing.

The experiment was conducted in a 2x2x4 factorial design in a completely randomized design. Two levels of the varieties and enzyme were considered.
The experiment was carried out in a 6 x 3 factorial scheme, with six isolates of the fungus and three different culture media, in a completely randomized design with 5 replicates per treatment.
Each treatment was conditioned in collective plastic pots, using a completely randomized design, ten seedlings per pot, sphagnum substrate, and daily watering, and percentage survival was evaluated after 75d.
Total treatments were 56, laid out in completely randomized design. The purpose of the second experiment was to see how storage for 6 and 12 months at 4 and 15AdegC affects the clusters germination of AR79, primed for 48 h with -1.0 MPa KNO3 and PEG 6000.

Twelve dairy cows of same parity, stage of lactation, milk production level and body weight (285-360 kg) were randomly allotted to four treatments (T0, T1, T2 and T3) in such a way that each group had three animals under Completely Randomized Design. The animals received 250, 350 and 450 g of bypass fat supplementation in T1, T2 and T3 whilst animals in T0 served as control group.
The experiment was arranged in a completely randomized design that was factorial (4x2), with four drying air temperatures (75, 90, 105, and 120[degrees]C) and two initial moisture contents for the soybean grains (19 and 25% w.b.).
The study was executed in a net-house under natural conditions following completely randomized design. There were six treatments (0, 50, 100, 150, 200 and 250 kg K2O ha-1 ), each repeated thrice.
Temperatures were treated as different experiments and 7 heat exposure times were considered as treatments, which were arranged in a completely randomized design with five replications.
The experiment was a completely randomized design with 4 treatments and 10 replicates (each cup representing a replicate).
The experiment was laid down in completely randomized design with 5 replications each consisting of 7 treatments (including control).
Completely randomized design (CRD) with four replications was used.
