Abstract

The purpose of this research was to analyze the effect of Naftalene Acetic Acid (NAA) and Benzyl Amino Purine (BAP) on growth of potato plantlet (Solanum tuberosum L.). This research used factorial Completely Randomized Design (CRD). The first factor was the concentration levels of NAA (A1 = 0,5 ppm A2 = 1.5 ppm and A3 = 2.5 ppm). The second factor was the concentration levels of BAP (B1 = 1 ppm B2 = 2 ppm and B3 = 3 ppm). Parameter observed were number of nodes, number of branches, number of roots, percentage of life explants, and percentage of damaged explants. Data were analyzed with analysis of variance and continued by Least Significance Different (LSD). The results showed that NAA 0.5 ppm increased the number of nodes, branches, and  roots compared to other treatments. The concentration of BAP 1 ppm increased the number of roots compared to other treatments. The concentration of NAA 0.5 ppm and BAP 1 ppm showed the best percentage of life explants (100 %) and showed the minimum percentage of damaged explants (0 %).

Abstract

One of phosphate (P) fertilizer i.e. SP-36 is expensive and can be obtained by rock phosphate (RP). Rock phosphate combined with Vesicular Arbuscular Mycorrhizal fungus (VAM) could increase Pavailability. VAM consists of many species, so it is necessary to test the role of VAM species on cherry tomato plant. This study aims to examine the effect of VAM species and phosphate fertilization to improve cherry tomato production. The research use a Completely Randomized Design (CRD) which consisted of two factors with three replications. The first factor is the phosphate fertilization (P0= without P fertilizer, P1= SP-36, P2= rock phosphate) and the second factor is VAM species (M0= control without mycorrhizae, M1= Glomus etunicatum, M2= Glomus fasciculatum, M3= double inoculation of G. etunicatum and G. fasciculatum). The results show that mycorrhizae inoculation increases plant height, fruit number, fruit weight and accelerates flowering age compared to without inoculation. BP fertilization increases fruit weight. BP+CMA produces number of fruit equivalent to SP-36+CMA. BP+G. etunicatum treatment significantly increases fruit weight compared to SP-36+G. etunicatum. G. etunicatum inoculation gives the highest fruit weight compared to other inoculation.

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.
