Study of Nitrogen Fertilizer Concentration and Types of Growth Regulators in Vegetative Growth of Orchid Plants (Dendrobium spp) Abdul Wachid
Nabatia Vol 1 No 1 (2010): June
Publisher : Universitas Muhammadiyah Sidoarjo

This study was conducted to determine the initial growth of orchids from application of various concentrations of nitrogen and various growth regulators. The location is at the experimental study of Agronomy, Faculty of Agriculture, University of Muhammadiyah Sidoarjo at a height of 5 m. The factorial experiment arranged in a randomized block design (RBD) with three replications. The first factor is the concentration of nitrogen fertilizer consists of : without fertilizer N (N0), 0.3 g/l of water (N1), 0.6 g/l of water (N2), and 0.9 g/l of water (N3); the second factor is a growth regulator (PGR) consists of: without PGR (Z0), dekamon Z2 (Z1): ergon (Z2), and gibberellins (Z3). Penenlitian results showed: (i) there is no interaction between dose and concentration of nitrogen fertilizer plant growth regulator on all variables of plant growth, (ii) the concentration of nitrogen effect on all variables were observed, as well as PGR types, except the variable plant height, (iii) combined treatment of nitrogen fertilizer dose (0.6 g/l of water) with gibberelin provide the highest stem diameter (18.33 mm) and the highest number of leaves (7.67 strands) at the age of 105 HST.

The Effect of Various Tricoderma sp. Isolate As TRICHOCOMPOST Fertilizer In Tomato (Lycopersicum esculentum Mill) Growth And Yield Abdul Wachid; Laili Fitrianisyah

The main objective of this investigation was to study the effects of TRICHOCOMPOST treatments on some vegetative growth and yield characters of tomato plants. This experiment was conducted at theyard area of Wates, Kedensari Village, Tanggulangin and Agricultural Research and Experiment Center, Muhammadiyah Sidoarjo University, during Februaryto August 2018. This research used a single factor Randomized Complete Block Design (RCBD) with compost fertilizer without Trichoderma sp. as control, Trichoderma sp. Claket isolate, Trichoderma sp. Jatijejer Isolate, dan Trichoderma sp. Jatirejo isolate as the main factor, 8 treatment levels and repeated 4 times. Then differences in the average value proceed used Honestly Significant Difference (HSD) at 5% level. The obtained results indicated generally that the effects of Trichocompost with Jatirejo isolate (P3) treatments reflected significant differences among the mean values of number of leaves plantand number of branch plant characters. Trichocompost with Jatijejer isolate (P2) reflected significant differences amongroot wet weight, Trichocompost with Jatirejo isolate (P3) reflected insignificant difference on plant characters than P0 treatment, however the treatment has the highhest mean value among the number of flower, the sum of fruit, and plant dry weight.
