PENDUGAAN PRODUKTIVITAS PADI SAWAH BERDASARKAN REFLEKTANSI (INDEKS VEGETASI), WARNA DAN KERAPATAN TANAMA

Abstract

Production of paddy in a different place is caused by several factors such as soil type, soil
nutrient content, pests and diseases, climate change and cultivation techniques. Because of
these differences, to find out the productivity of land in a large area needs technology so that
the results are more appropriate. For this reason, this study was conducted with the aim of
estimating land productivity using technology that reflects plant reflectance in several cropping
patterns. , taking a portrait of land appearance and measuring grain productivity to be used as
validation data. The data is processed by linking reflectance (vegetation index), color, plant
density and productivity of paddy rice in the same area. The results show that there is a
relationship between plant density with the productivity of paddy fields (tons/ha) with a
coefficient of determination (R2) that is 0.7. Rice plants in Legowo 2-1 cropping pattern have
more influence on the index increase compared to the Tegel planting pattern. The relationship
between the vegetation index and rice productivity (tons/ha) is weak in SR, NDVI, SAVI, MSAVI,
and IPVI and is strong in RDVI
