| Summary: | Black rice is one of the local cultivars that contain high antioxidants, fiber, <br />
<br />
vitamin E and are good for the health of the human body. However, the <br />
<br />
productivity of black rice is still very low with a long harvest age (4-5 months) <br />
<br />
and a small amount of quality seeds. One way of developing black rice in order to <br />
<br />
increase its growth and productivity is through the provision of growth hormones <br />
<br />
such as auxin (NAA) with the SRI method in the cultivation process. The purpose <br />
<br />
of this study is to determine the effect of NAA concentration differences on the <br />
<br />
growth and yield of black rice var. Cempo Ireng and determine the concentration <br />
<br />
of NAA hormone to increase growth and yield of black rice var. Cempo Ireng <br />
<br />
using SRI method. The study was conducted using a Randomized Block Design <br />
<br />
(RCBD) consisting of 4 treatments and 7 repetitions. The treatments consisted of <br />
<br />
4 concentration levels, namely concentrations of 0 ppm (A), 20 ppm (B), 40 ppm <br />
<br />
(C), and 60 ppm (D). The results of the study shows that it is not significantly <br />
<br />
affected by each treatment both on the parameters of growth and yield of plants. <br />
<br />
However, the treatment concentrations that capable of giving the best results are <br />
<br />
concentration of 20 ppm and 40 ppm. Growth parameters include: plant height, <br />
<br />
number of tillers, and panicle number at concentration of 20 ppm is given 75.81 <br />
<br />
cm, 43 tillers, and 24.71 panicles. Whereas for crop yield parameters (harvest <br />
<br />
index and productivity) the average values in sequantially are 46.67% and 5.055 <br />
<br />
tons / ha / year. The best crop yield parameters for 1000 grains and filled panicles <br />
<br />
per panicle were obtained at a concentration of 40 ppm respectively are 27.96 <br />
<br />
grams and 139.05 filled grains. |
