A factorial experiment was conducted with a completely randomized design to evaluate the effects of planting date and density on calendula herbs and peppermint. It had 3 replicates and was done in Khosroshahr research farm, Tabriz in 2006. Under studied factors were: 3 planting dates (10 May, 25 May and 10 June) in 4 densities (25, 35, 45, 55) of the plant in square meters. The results of variance a nalysis showed that there was 1% probability significant difference between the effects of planting date and bush density on the leave number, bush height and the bush dry weight. But the mutual effect of the plant date in mentioned traits density was insignificant. Regarding the traits mean comparison, the total maximum dry weight was about the 55 bush density in mm. Also, the bush high density in mm causes the bush growth and its mass reduction. When there is the density grain, the flower number will increase due to bush grain in surface unit. Overall, we can conclude that 10 June planting and 45 bush density in mm is the most suitable items and results in favored production with high essence for these crops.

Moler disease is the primary disease that disturbs the shallot’ cultivation. Hence, it is beneficial to have preventive measures to mitigate the risk and to improve growth. The research objective is to know the effectivity of Trichoderma harzianum suspension as a bio-fungicide and bio-stimulator. The study used seven treatments, i.e., immersion of shallot seeds on negative control (distilled water), positive control (synthetic fungicide+ZPT 1g/liter), T.harzianum suspension with different concentrations of 2 ppm, 4 ppm, 6 ppm, 8 ppm, and 10 ppm, assigned in a Completely Randomized Design (CRD). Treatment that results in a significant level will be continued to the Least Significance Different (LSD) 5% test. The observed variables are the intensity of moler disease and the growth of shallot seeds. Experiment results show the significant difference between treatments. The optimal treatment to reduce the percentage of moler disease intensity is the immersion of shallot seeds in 10 ppm-concentrated T.harzianum suspension, while to improve the shallot growth is in 8 ppm-concentrated T.harzianum suspension. The intensity of moler disease has a negative correlation to the plant’s height and leaf’s diameter but shows no correlation pattern to the number of leaves, wet weight, dry weight, and length of roots.

Background: The beneficial elements availability such as silicon was determined rice growth and yield. Rice requires a different dose of silicon during the growing period. Experiment was aimed to investigate the effect of silicate levels, rice varieties and the interaction of the two on the growth and yields of two local Indonesian varieties of rice. Methods: A completely randomized design of factorial pattern with 4 replications was used in the experiment. Treatments consisted of No added SiO2 (Si-0); added 100 and 200 kg SiO2 ha-1, respectively for Si-100 and Si-200 and two local rice varieties, Pandan wangi (P1) and Mentik susu (P2). Result: The treatment had no significant effect on growth and yield of rice. Addition of 100 and 200 kg SiO2 ha-1 to P1 and P2 did not show a significant difference on the growth and yield of rice compared to control (P0). Plant height and root dry weight at P1 was lower than P2, but the 1,000-grain weight was showed, vice versa. Silicon addition up to 200 kg SiO2 ha-1 may not be recommended to be applied in rice cultivation, especially Pandan wangi and Mentik susu varieties. Improving the two varieties, further research is needed by increasing the silicon doses.
