Influence of Manure And Pgr Cosentration OnGrowth of Pakchoy (Brassica Chinensis)
Full text linkAbstract: The purpose of this research is to determine interaction between composition of growingmedium, PGR concentration to growth, influence of composition of growing medium toward growth andharvest of pakchoy. The present study uses factorial randomized group design consisting of two factorswith three replicates and 2 sample plants. Factor I is growing medium composition of 3 levels whilefactor II is a level 3 PGR concentration. The composition of these factors is factor I: M3 garden soil: 1manure, M2 =2 garden soil: 2 Manure, M3 =1 =1 garden soil:3 manure. Factor II consists of: K= 2ml/liter of water, K2= 4 ml/liter of water, K= 6 ml / liter of water. Results from this study indicate that the combined treatment of manure and PGR concentration has significant effect on observation of plantlength at 28 days of age. However, it does not give real interaction to variables of number of leaves, plantlength, and gross at all ages of observation. The use of manure has significant effect on all observationvariables. The highest average plant length, leaf number, and highest gross were obtained at the treatment of M23(2 garden soil: 2 manure). Treatment of PGR concentration had significant effect on allobservation variables. Average length of plants, number of leaves, and highest gross were obtained at treatment of K2 ml / ltr water
The Effect Of Sawdust And Chaff Media Storage OnCocoa (Theobroma Cacao L.) Seeds Viability
No full textAbstract: The objective of the research is to determine the effect of sawdust and chaff media storage on viabilityof cocoa (Theobroma cacao L.) seeds. Cocoa seeds’ viability need to be maintained duringstorage/shipment to planting destination. The research uses simple group randomized design (RAK)consisting of five (5) treatment with three (3)replicates. Assignment of treatment is carried out inrandomized trial plots. The varieties tested is F1 hybrid varieties obtained from Indonesia Coffee andCocoa Research Center. The parameters observed included percentage (amount) of germination, rate ofgermination, and gross weight of sprouts. The result indicates shows that media storage treatment usingsawdust and chaff provides significant effect on the percentage (number) of seeds germinate, sprout andspeed or rate of gross weight of cocoa seed sprouts. In addition, control treatment (storage without chaffor sawdust) resulted in the highest percentage (number) of germinated seed, while the highest germinationrate and gross weight of sprouts is indicated by treatment of storage with chaff of 100% although notsignificantly different statistically with 50% chaff.Keywords: Cocoa Seed, sawdust and chaff, , RAK
The Influence of Immersion Duration and Organic Growing Organics on Sugar Cane (Saccharum omcinarum L) Growth and Yield
Full text linkAbstract: The purpose of this research is to determine the influence of interaction between organicgrowth regulator concentration and immersion duration time, as well as the influence of each of thesefactors on germination sugarcane (Saccharum officinarum L)cuttings. This study uses a randomizedgroup design (RAK) with two factors, immersion duration (P)in 4 levels of P1 (1 minute), P2 (2 min),P 3 (3minutes), and P4 (4 minutes) and two levels of organic plant growth regulator (K), 4 cc/ liter, and 5cc per liter of water, each treatment is repeated 3 times to obtain 24 treatments. The results revealsthat a)There is a significant interaction effect due to immersion duration and concentrations of organicgrowth regulator to the observed variables: number of roots per plant, root length per plant, gross weightper plant and net weight per plant at the end of the observation b). Each factor of both immersion andconcentration of organic plant growth provide significant influence on all the variables studied. 0). Thehighest value on all the variables observed is achieved by K2P4 treatment with concentration of 5 cc/literand 4 minutes immersion; yet statistically, the optimum value is achieved by treatment K2P3 or influenceof K2 and P3treatment
Application of IBA PGR Concentration On Germination of Sugarcane (Saccharum Officinarum L) Cuttings
Full text linkoai:ojs2.agriscience.scientific-work.org:article/1Abstract: The purpose of this study is to determine the effect of IBA plant growth regulators (IndoleButyric Acid)on germination of sugarcane cuttings (Saccharwn o_mcinarum L). The experimentalmaterials include PSJT 941 variety of sugarcane cuttings, soil and manure as medium with 2: 1ratio. IBA and 50% alcohol is used as treatment. Pest and disease controls used Basudin 60 EC andDithane M-45. This study uses Randomized Block Design (RAK) with three replicates and each replicateconsisted of 2 sample plants. The treatment is as follows: Ko: without treatment, K1: 500 ppm, K2: 1000ppm, K3: 1500 ppm, K4: 2000 ppm. The study reveals that treatment of K4 IBA solution (2000 ppm)hasvery significant effect on variables of germination speed, shoot length, number of leaves and number ofroots, and significantly different at root length. Administration of IBA solution at concentration of 1500ppm accelerated germination time of sugar cane cuttings, occurred on the fourth day(fourth). Administration of IBA solution at 2000 ppm gave the highest result which was not different with1500 ppm concentration on shoot length, leaf number, root length and root number. The higher theconcentration of IBA, the higher the shoot length, the number of leaves, the length of the roots and thenumber of roots of sugar cane produced
The Effect Mnure And Concentration Of Em-4 DoseOn Plant Growth And Yield Of RedSpinach (Alternanthera Amoena Voss)
Full text link1,Sri HidayatiFaculty of AgricultureAgrotechnology Study program1,2,3Merdeka University SurabayaE-mail: [email protected],NurlinaAbstract: The purpose of the study to determine the effect of various doses of manure on the growth andyield of red spinach. Randomized Factorial Experiment is used with three replications. The first factor isthe dose Manure P1 = 5 tons/hectare; P2 = 10 ton/ hectare; P3 =Dose manure 15 t / ha. The second factoris the concentration of EM-4, among others K1 = dose of 5 ml/liter of water/polybag; K2 = dose of 10ml/liter of water/polybag; K3 = dose of 15 ml/liter of water/polybag. Of the two factors 9 combinationtreatments are obtained which was then repeated 3 times. There was no significant interaction at F5% testlevel on all variables studied i.e plant height, leaf number and gross weight per plant at all age ofobservation. There were significant effects of manure dose factor studied, mainly on plant heightvariables, number of leaves and gross weight per plant; and statistically, a better value in all of thesevariables is achieved by treatment P3 manure dose of 15 ton/ha. EM-4 concentration factor hassignificant influence on plant height variables, number of leaves and gross weight per plant; statistically, abetter value in all of these variables are also achieved by treatment of the K3 of 15 ml/liter ofwater/polybag.Keywords: Spinach , Manure, EM-4, RA
