Abstract

This study aims to determine the response of growth and  production  of  shallot  (Allium cepa L.) to the Nitrogen fertilizer and Granule Organic fertilizer. The design used was a Factorial Completely Randomized Design consisting with two (2) treatment factors. The first factor is Nitrogen (N) from Urea which consists of three levels, namely: N1 = 2 g / plot, N2 = 4 g / plot and N3 = 6 g / plot. The second factor of Organic Granule fertilizer consisted of three levels, namely: G1 = 5 kg / plot, G2 = 10 kg / plot, G3 = 15 kg / plot. The results showed that interaction of Nitrogen fertilizer  and Granul Organic fertilizer significantly affected plant height, number of leaves, number of tillers and tubers wet weight per plot, but not significant for the number of flower stalks. The highest growth and production of shallots produced a combination of treatment N3 = 6 g / plot and G3 = 15 kg / plot.

Abstract

Screening of candidate tolerant potato (Solanum tuberosum L.) to drought in vitro from callus was aimed to determine the growth and proline content of potato plants. This research was conducted at the Laboratory of Tissue Culture of Dinas Pertanian of North Sumatra Province, Jl Karya Jasa No 6 Gedung Johor Medan, in May 2012 until May 2013. The initial research was callus formation followed byorganogenesis. Then, was treated by PEG, 1000, 2000 and 3000 ppm. The result indicated that increased concentration of PEG decreased the amount of leaves and number of internodes. The higher the PEG concentration, the higher the proline content of potato in vitro.

Abstract

Preliminary studies in Screening of Potato (Solanum tuberosum L.) as a result of drought stress (in vitro). This study aim was to determine the limits of potato (Solanum tuberosum L.) to drought stress conditions in vitro using PEG. This research was conducted at the Tissue Culture Laboratory Unit / Laboratorium Kultur Jaringan UPT/Balai Benih Induk Hortikultura Dinas Pertanian Propinsi Sumatera Utara, Jl. Karya Jasa No. 6 Gedung Johor Medan in March 2012 to June 2012. The Completely Randomized Design (non factorial) was used with PEG concentrations of five levels, namely: P1 = 10%, P2 = 20%, P3= 30%, P4 = 40% and P5 = 50% with 5 replications. The results showed that increasing the concentration of PEG will reduce the percentage of plantlets survival, reduce plant height, number of roots and number of nodes. Treatment of 50% PEG resulted in the death of potato cuttings due to drought stress.

Abstract

THE EFFECTS OF NAA AND BAP ON Callus OF BANANA (Musa acuminata L) WITH THE ADDITION OF FUSARIUM WILT DISEASE FROM Fusarium oxysporum f.sp.cubense (Foc). This research was conducted on January to June 2016, at Tissue Culture Laboratory of Dinas Tanaman Pangan dan Hortikultura of North Sumatera Province, Jl.Karya Jasa No.6 Gedung Johor, Medan. The purpose of this research is to know the response of banana barangan callus (Musa acuminate L.) to fusarium (Fusarium oxysporum f. Sp.Cubens). The living callus is subsequently subcultured for organogenesis purposes by treatment of NAA and BAP. The research use Completely Random Design with two factors that is NAA and BAP. NAA consists of 3 levels: N1 = 1 ppm, N2 = 1.5 ppm and N3 = 2 ppm. The second factor using BAP consists of 3 levels: BA1 = 1.5 ppm, BA2 = 3 ppm and BA3 = 3.5 ppm. The results showed that the percentage of live callus after fusarium addition was only 33.33%, interaction of NAA and BAP did not significantly affect the percentage of live plantlets and wet weight of banana plantlet. The highest percentage of live plantlet on aged 9 - 13 week after subculture and the highest wet weight of planlet found on N1(1 ppm) each 7.05 % and 3.62 g, while the highest percentage of live plantlets on aged 9 - 13 Week after subculture and the highest wet weight of plantlet found on BA1 (1,5 ppm) each 5.69 % and 3.38 g. The treatment combinations that gave the highest percentage of planlets live and wet weight of planlet were N1BA1 and N1BA2.

Abstract

Background and Objective: The role of phosphorus and nitrogen is very important for the metabolism of oil palm plants in the nursery phase. This study aims to determine the morphophysiological performance of oil palm (Elaeis quineensis Jacq) seedlings in the pre-nursery due to the application of SP-36 fertilizer and urea. Materials and Methods:The research was conducted on Jln. Bunga Ncole Permai, No.30 Medan Tuntungan District with an altitude of ± 20 meters above sea level. This research is done June 2021 to August 2021. The study used a factorial Randomized Block Design with two factors. The first factor is the dose of SP-36 fertilizer with 3 levels of S1 = 5 g/polybag; S2 = 10g/polybag; S3 = 15 g/polybag. The second factor is the dose of urea fertilizer with 3 levels: U1 = 3 g/polybag, U2 = 5 g/polybag and U3 = 7 g/polybag. Results: The results showed that the dose of SP-36 fertilizer had a significant effect on stem diameter at 12 WAP, number of leaves at 8, 10 and 12 WAP, and leaf length at 10 and 12 WAP. The urea dose treatment significantly affected plant height at 6, 8, 10, and 12 WAP, stem diameter at 10 and 12 WAP, number of leaves at 6, 8, 10 and 12 WAP, and leaf length at 8, 10 and 12 WAP. The interaction between the two treatments did not have a significant effect on all ages of observation. Conclusions: the best oil palm seedling growth was found in the treatment of SP-36 S3 fertilizer dosage = 15 g/polybag and urea 7g/polybag.
