Abstract

This study aimed to determine the effect of a combination of cropping systems and the number of plant seeds on the growth and yield of black rice plants. The research method used a simple randomized block design (RBD) model consisting of 6 treatment combinations with 4 replication, namely: 1) Combination of 25 x 25 tile planting system and one seed (J1B1), 2) Combination of 25 x 25 tile planting system and two seeds (J1B2), 3) Combination of 2:1 legowo cropping system and one seed (J2B1), 4) Combination of 2:1 legowo cropping system and two seeds (J2B1), 5) Combination of 4:1 legowo cropping system and one seed (J3B1), and 6) Combination legowo 4:1 cropping system and two seeds (J3B2). The results showed that the combination treatment of different cropping systems and number of seeds affected the observation of plant height at 4, 6, and 8 week after planting (WAP), as well as the number of tillers at 4, 6, and 8 WAP; number of productive tillers aged 6 and 8 WAP. Meanwhile, the combination treatment of different planting systems and the number of seeds had no effect on plant height at 2 WAP, number of tillers at 2 WAP, and HGW/plant weight. The combination of the 2:1 legowo cropping system with the number of one seed gave the best effect on observing plant height, number of productive tillers, number of panicles, and weight of 100 HGW grains. However, the combination treatment of different cropping systems and the number of seeds resulted in the same or not significantly different dry harvested grain weight (HGW) and milled dry grain weight (DGW).

Abstract

Sustainable agricultural policies encourage agricultural innovations such as the use of bio saccharides as elicitors in plants. Biosaka contains chemical compounds that trigger a positive response in plants. Shallots are a superior commodity whose cultivation practices often do not pay attention to the negative impacts on the environment. Using biosaka as an alternative can support more environmentally friendly shallot farming. This research aims to identify the effect of using a biosaka elicitor on the growth and production of shallots. The research was carried out from July to September in Kab. Subang, West Java with an altitude of 10 m above sea level. The biosaka elicitor treatment was carried out using 3 treatment formulas, namely A: formula 1 (babadotan, kitolod, anting-anting, maman lanang, and pasang bumi), B: formula 2 (jelantir, sembung, patikan kebo, meniran, and sembung rambat), C: formula 3 (babadotan, anting-anting, sembung, jelantir and meniran), D: control (without elicitor), treatment was repeated 6 times. The results of the research show that all weed-based bio saccharide elicitor formulations can increase plant height, number of leaves, and weight of onion bulbs. Selection of appropriate elicitors with appropriate cultivation techniques can produce optimization plant product.
