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

The research was aimed to examine the effect of different concentration of KNO3 and fruit maturitylevel on the seed viability of papaya. This research used Completely Randomized Design (CRD)factorial with two main treatments. The first treatment was fruit maturity level (A0 : 75% dan A1 :100%). The second treatment was concentration of KNO3 (B1 = 0 M ; B2 = 0,05 M ; B3 = 0,1 M ; B4 =0,15 M ; B5 = 0,2 M). Seedling parameters observed were germination rate, seed growth rate, vigourindex, and maximum growth potential. Nursery parameters observed were plant height and leaf area.Data were analyzed with Analysis of Variance (ANOVA) followed by Duncan Multiple Range Test(DMRT) at 5%. The interaction between fruit maturity and KNO3 concentration showed significantly ingermination rate, seed growth rate, vigour index, maximum growth potential and plant height. Leafarea were only affected by KNO3 concentration. This showed that fruit maturity level and KNO3concentration were significantly affects seed viability.

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 increaseP availability. VAM consists of many species, so it is necessary to test the role of VAM species oncherry tomato plant. This study aims to examine the effect of VAM species and phosphate fertilizationto 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= doubleinoculation of G. etunicatum and G. fasciculatum). The results show that mycorrhizae inoculationincreases plant height, fruit number, fruit weight and accelerates flowering age compared to withoutinoculation. BP fertilization increases fruit weight. BP+CMA produces number of fruit equivalent to SP36+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 aim was to estimate the variability value and heritability of quantitative and qualitative character on F4 generation from crossing Fagiola IPB and Super Putih. The observed parameters were plant height, number of leaves, number of branches, the day of flowering, length of young pod, pod color, number of pod, number of seeds, seed weight, weight of one seed, weight of 100 seeds, and sweetness. Data were analized by Analysis of Variance, Genetic Variability, and Heritability. The result showed that only character of seed weight per plant had high genetic variability. The characters of number of leaves, number of branches, length of young pods, number of old pods, number of seeds, weight of seeds, one seed weight, and weight of 100 seeds had high heritability. The day of flowering and sweetness had low heritability. The results of the dendogram analysis showed that group C was recommended for next generations.

Abstract

Ginger (Zingiber officinale Rosc.) is one of the medicinal plants and can be processed into products such as essential oils and starches. Ginger was planted under a tree because it has a good sunlight tolerant plant. Ginger can grow and develop normally, even in low light intensity. Indonesia has a lot of land with shade conditions and potential for ginger production. It can be supported to increase national ginger production. This study aims to assess the growth and development of ginger in Gajah variety, with several genotypes, that are cultivated as intercropping at Jatropha curcas. The study was conducted in Jatropha plantation at 2.144 dap age, which is located at Desa Kedungpenggaron, Kec. Kejayaan, Pasuruan city (117 m above sea level, with coordinates 7 ° 46'18.6 "112 ° 50'25.2"). The study began on October 2017 to March 2018. The study used Gajah variety, with 10 genotypes, consist of Banyuwangi, Sidoarjo, Malang, Bojonegoro, Jombang, Bandung, Purwakarta, Banten, Lampung, Jambi, which were arranged in a Randomized Block Design. The results showed that ginger's growth and development at 14 to 105 dap was not significantly different in all parameters. Based on cluster analysis for 14 quantitative variables, showed that two grouped, specifically 9 genotypes and 1 Lampung's genotype with 31.71% similarity. The similarity of Ginger Gajah, approved by the Banyuwangi and Jombang genotypes, which reached 86.26%
