The provided charts illustrate the monthly weight of fruit produced, the quantity of fertiliser applied, and the volume of rainfall recorded throughout 2013. Overall, fruit production followed a clear upward trend until September, whereas fertiliser usage and rainfall levels fluctuated significantly throughout the year.
Fruit production began at 2.1 tonnes in January, rising steadily to reach a peak of 4.2 tonnes in September. Following this, production dropped sharply, returning to 2.1 tonnes by December. Conversely, fertiliser usage showed a different pattern, peaking at 0.9 tonnes in April before plummeting to near-zero levels between May and June. A secondary, smaller peak in fertiliser application occurred in November at 0.7 tonnes.
Regarding rainfall, the highest levels were recorded in February at 16 mm, followed by a gradual decline to a low of 4 mm between July and September. Rainfall then increased again towards the end of the year, reaching 14 mm in December. There appears to be an inverse relationship between rainfall and fertiliser usage during the mid-year period, as the driest months coincided with the lowest fertiliser application, while the highest fruit yields occurred during the period of lowest rainfall.
