Question

working in ghana, emmanuel hanyabui and colleagues compared the impact on pineapple growth of different combinations of soil additives, including npk fertilizer (an inorganic fertilizer containing nitrogen, phosphorus, and potassium), organic compost, and biochar (a carbon - rich material produced from organic waste matter). based on data in the table, pineapple farmers with no access to inorganic soil additives would likely increase the weight and size of their fruits by the greatest amount by using
which choice most effectively uses data from the table to complete the text?
a. biochar and npk fertilizer.
b. biochar and compost
c. biochar alone
d. compost alone

Explanation:

The question asks which soil treatment (without inorganic NPK fertilizer) gives the greatest increase in weight and size. Looking at the data:

• Option A includes NPK (inorganic), which is not allowed as per the question (farmers have no access to inorganic additives).
• For weight: Control (825.9), Biochar (915.7), Compost (864.8), Biochar and compost (979.5). Biochar and compost has a higher weight than Biochar alone and compost alone.
• For length: Control (6.14), Biochar (6.66), Compost (6.15), Biochar and compost (6.76). Biochar and compost has a higher length than Biochar alone and compost alone.
• For diameter: Control (13.63), Biochar (13.63), Compost (13.22), Biochar and compost (13.68). Biochar and compost has a higher diameter than Biochar alone (same as control in diameter for Biochar) and compost alone.

Answer:

B. biochar and compost
