Abstract

This study aims to evaluate the growth and production of cassava due to micro fertilizer. The cassava clones used are BW1, Kasetsart, Cimanggu, Purple Kasetsart, BL1, Mulyo and UJ5 (as comparison clones) with the planting space of 1m x 0,5m . This research was conducted on Sukanegara Village, Tanjung Bintang Subdistrict, South Lampung from July 2018 until May 2019. The treatment was arranged by factorial (7 x 2) in a Randomized Block Design (RBD) with two replications. The first factor was seven clones, namely BW1, Kasetsart, Cimanggu, Kasetsart ungu, BL1, Mulyo and UJ5 (as comparison clones). The second factor was 2 levels of micro Zink fertilizer dosage, namely 0 kg ha-1 and 40 kg ha-1. The variables observed were plant height, diameter of root distribution, root number, root weight and starch content. Data were analyzed using SAS 9.0 software application with significant level of 5%. The results showed that the difference in the mean height of the highest plant height, 5.25 cm in BW 1 clone compared with the UJ5 comparison clone. Furthermore, the difference in the middle diameter diameter of the highest sweet potato distribution in BL1 was 7.83 cm. The highest number of cassava is 7 fruits per plant with the weight of sweet potato is 1010 g / tnm. In addition, the results of the measurement of starch levels showed that the Cimanggu clone with the addition of 40 kg Micro Zink ha-1 had the highest starch content of 28,6% compared to UJ5 which had a starch content of 25,7%. In contrast to the treatment of 0 kg Micro Zink ha-1, Mulyo clone has the starch content as 27,9% compared to the UJ5 which is 27,0%. Keywords: cassava, clone, micro nutrient, production
