Abstract

This study was conducted from February s / d May at the Institute for Agriculture and Technology (BPTP) East Kalimantan, this study aims to look at the different types of growing medium and the addition of TSP fertilizer in cultivation of oyster mushroom (Pleurotas astreatus) [Jacq FR] Kummer) .This research used Completely Randomized Design (CRD) factorial with two factors, factor 1: type of planting medium consisting of 2 treatment levels, namely (1. Straw Rice, 2. Powder Saws), 2: Type of fertilizer treatments consisting of 1 level namely (1. controls, 2. TSP 0.2%, 3. TSP 0.4%, 4. TSP 0.6%). Each treatment loaded with 5 replicates the data obtained were analyzed with ANOVA and if significant then further tested by using Duncan C DMRT at 95% confidence level, while the relationship between the effect of concentration (treatment) with the observed parameters analyzed with regression Simple linear. Parameters measured were emerging mycelium first time (hst), mycelium meets media (HST) initial appearance of the fruiting bodies (hst), the time of harvest, the number of fruiting bodies, hoods maximum width, stem length fruiting bodies, and the weight of the fruit.Results indicate that the rice straw media with TSP fertilizer as much as 0.6% on average produce mycelium formed fastest time is 3 DAT (Days After Planting, average fruit weight of 103.74 grams.Compared with sawdust medium with fertilizer TSP as much as 0.6% on average produce mycelium formed fastest time is 7 HST average body weight of 105.64 grams of fruit.Conclusions obtained from the results of the study showed that the rice straw media faster than the appearance of mycelium on sawdust media. But for a number of shoots on media more than the media sawdust rice straw.

Abstract

The study aimed to determine the effect of compost and NPK Pelangi compound fertilizer and their interaction on the growth and yield of beans.The study was conducted in February-May 2016. The location of the study was in Linggang Amer Village, Linggang Bigung District, West Kutai Regency. The research design used was a Completely Randomized Design (CRD) in a 4x4 factorial experiment with 3 replications. Factor I: dosage of compost (B), consists of 4 levels, namely: without fertilizer or control (b0), fertilizer dose of 10 tons / ha or 100 g / polybag (b1), fertilizer dose of 20 tons / ha or 200 g / polybag (b2), fertilizer dose of 30 tons / ha or 300 g / polybag (b3). The second factor: the dose of NPK Pelangi (P) compound fertilizer, consists of 4 levels, namely: without fertilizer or control (p0), 1 g / polybag (p1) fertilizer dose, 3 g / polybag (p2) fertilizer dose, 5 fertilizer dose g / polybag (p3).The results showed that compost treatment (B) had no significant effect on the height of plants aged 10 and 30 days after planting, the number of fruit per plant and the weight of fruit per plant. The effect is very significant on plant height aged 20 days after planting and fruit length. The treatment of NPK Pelangi compound fertilizer (P) had no significant effect on plant height aged 20 and 30 days after planting, fruit length, number of fruit per plant and weight of fruit per plant. Significant effect on plant height at 10 days after planting.
