Answers
Answer:
a.) no all plants will not grow at the same rate
b.) growth of plant is best in case of manure because these are naturally made. Manures are a rich source of nitrogen as well as other nutrients. Since manure is a waste product, it must be used carefully. Raw manures may be used, but there is odor associated with unbroken down waste, as well as the flies that it attracts
c.) growth in pot c in case of fertilizer will be faster as they are containers of chemical and chemical reacts quickly on soil as per plant growth. Fertilizers are economically very beneficial to farmers. They expedite plant growth and are not very expensive to procure. Fertilizers also increase the yield from a farm. The plants also have a superior appearance i.e. they appear greener and healthier when we use fertilizers. but In real these damages soil leading to its degradation
