Abstract

Basil is a spice plant that is widely used as a culinary additive, fragrance, atractan, and anti-bacterial because it produces essential oils, basil oil. This research aimed to identifying the affect of adding rice husk ash on different basil’s cultivars on growth and yield of basil (Ocimum basilicum). This research use 4 x 2 factorial experiment pattern with Completely Randomized Design consisting of 5 replication. The first treatment was various type of basil’s cultivars such as Genovese cultivars (K1) and Dark Opal cultivars (K2). The second treatment was doses of rice husk ash such as control or without giving rice husk ash (M0), 30 g/pot (M1), 35 g/pot (M2), dan 40 g/pot (M3).  The observed parameters were soil bulk density and porosity, plant height, leaves total, roots length, and leaves simplisia. The results showed that the application of husk ash can affect the increase in physical properties of the soil, but has not directly affected the growth parameters and yield of leaf simplisia. Dark Opal cultivars on all growth parameters showed higher yields, but Genovese cultivars showed higher yields or simplisia.

Abstract

This research aims to examine the effect of application bamboo root PGPR and rice straw compost on the physical quality of the soil, growth and production of the corn plant (Zea mays). This research was arranged in split plot design 3 x 4 with 3 replications. The main plot is rice straw compost (K): K1=10 ton/ha, K2=15 ton/ha, K3=20 ton/ha. The subplot is PGPR (P): P0= 0 ml/l (control), P1=10 ml/l, P2=15 ml/l, P3=20 ml/l.  The parameters observed were soil porosity, soil water content, plant height, number of leaf, cob length, cob weight, weight of seed and field. Data were analyzed extensively and continued with Duncan Multiple Range Test (DMRT). The results showed that the treatment of PGPR and rice straw compost increases with the addition of dose. Treatment of PGPR provide a significant response to increase in the porosity, soil water content and number of leaf compared to the control, while the length of cob and weight of seed showed an increase in the addition treatment of a dose compost and PGPR. Treatment of PGPR or rice straw compost has yet to show a response different to the plant height. The interaction treatment significant on the weight of cob and field. The results of the optimal corn crop is achieved at the treatment dose of 15 ton/ha compost straw combined with PGPR dose of 15 ml/l.
