RESPONSE OF SEVEN VARIETIES OF RICE PLANT WITH GIVE STEM BANANA LIQUID ORGANIC FERTILIZERS AND COCONUT FIBER LIQUID ORGANIC FERTILIZERS ON PLANT GROWTH

Abstract

Rice is a staple crop that cannot be replaced by other plants in people's lives in Indonesia. Therefore, efforts are always made to increase rice production in the form of intensification, one of which is by providing organic fertilizer so that the fertilizer given is in accordance with plant needs. Organic fertilizer contains complete nutrients, both macro nutrients and micro nutrients. One of the organic fertilizers that can be given is liquid organic fertilizer (LOF) made from natural ingredients such as coconut fiber and banana stems. The raw materials for making LOF are very easy and cheap to obtain because they are widely available in the community. The aim of this research is to obtain lowland rice varieties that respond to banana stem LOF and coconut fiber LOF in increasing rice plant growth. The design used was a Randomized Block Design (RBD) with 7 variety treatments (Bawaan, Bujang Marantau, Cisokan, Inpari Gemah, IPB3S, IR42, and PB42), each treatment was grouped into 4 groups. The observation data was analyzed using the F test at a 5% real level and if significantly different, it was continued with a further DNMRT test at a 5% real level. The results obtained were the growth of lowland rice plants where the seven varieties responded differently to the provision of coconut fiber LOF and banana stem LOF. These results showed that the Bawaan variety responded more to LOF on plant height (86.45cm) and leaf area index (2.97m2/week), and the IPB3S variety responded more to LOF on the number of tillers (61.8 stems).
