Abstract

This study used a randomized block design Factorial with two factors, namely the differences of some type sour orange (Citrus sp) (J) with 3 levels ie J1 citrus musk (Citrus mitis), J2 lime, J3 (Citrus hystrix). The second factor is the provision of onion extract concentration (B) with 3 traf, namely (B1) onion extract concentration of 25%, (B2) onion extract concentration of 50%, (B3) concentration of garlic extract merah75%. The results showed growth of shoot cuttings of lemon give the best effect against high Parameter shoots, number of leaves, number of shoot and root length. Onion extract with a concentration of 75% effect on age parameters appear shoots, shoot height, leaf number, number of shoot and root length. There is no interaction between several types of sour orange and red onion extract concentration levels on all parameters of observation.Keyword:  Concentration, Extrack Onion ,  Acid Orange

Abstract

The aims og this study was to investigate the response of several varieties and bio-organic fertilizer application on the growth and production of watermelon (Citrullus vulgaris Schard). The design used was a factorial randomized block design (RAK-F) with the two factors studied, namely: Factor watermelon varieties (V) consists of a 3-stage treatment that V1 = Varieties Sun Dragon F1, V2 = Varieties Funggawa, and V3 = Varieties Sire F1. Factors giving bio-organic fertilizer (B) consists of 4 levels ie B0 = Without treatment, B1 = 2 cc / l of water, B2 = 4 cc / l of water, and B3 = 6 cc / l of water. The parameters measured were plant height, days to flowering, number of fruits per plant, number of fruit per plot, weight of fruit per plant, fruit weight per plot.The results showed that administration of watermelon varieties can have real impact on the parameters of plant height 2MST. The best varieties are V2 = Variety funggawa. Organic bio fertilizer application significantly affected the parameters of age start flowering, number of fruits per plant, number of fruit per plot, weight of fruit per plant and fruit weight per plot. Concentration of bio-organic fertilizer is best to B3 = 6 cc / l of water. The interaction between varieties and the provision of bio-organic fertilizer giving real effect on plant height parameters 2 MST.Keywords: response, growth, bio-organic fertilizer, watermelon
