PaddyNet An Organized Dataset of Paddy Leaves for a Smart Fertilizer Recommendation System

PaddyNet- the dataset is used to helps of farmers and recommend need based nitrogen fertilizers. The entire data set is collected from the paddy fields in the Aman season by our own developed application with the tremendous help of Bangladesh Agricultural Research Institute (BARI), Jashore, Bangladesh and the office of the Upazila Agriculture officer near Jashore. We have used our application in Nokia 3 (8MP Camera) and Samsung S8 (12MP Camera) devices for collecting data. carefully labeled our total data set corresponding to the LCC level with the help of domain experts. Data validation has been carried out by the two principal scientific officers at Bangladesh Agricultural Research Institute (BARI) Jashore.

The color of the paddy leaf depends on the maturity as well as Nitrogen concentration. However, Nitrogen concentration can determine by analysing only the top most leaves. At first, a total of 560 top most paddy leaf images were taken. The resolution of the images were 500*500 pixels and we used our developed mobile application where each of 2 to 5 LCC level has 158, 162, 124 and 116 number of images respectively. Moreover, We have augmented initially our 560 paddy leaf images to 6000 where each LCC level has1500 paddy leaf images after augmentation and saved in the jpg file format.
