Abstract

Salak Sidimpuan leaf midrib is abundant pruning waste. Salak Sidimpuan leaf midrib can becomposted containing a number of nutrients (carbon, Nitrogen, phosphorus, and potassium) for plantgrowth. To speed up the process of composting of salak leaf midrib can be done by giving a numberof activators. This study aims to see the effect of activator on the level of elements C, N, P and Kcompost of salak Sidimpuan leaf midribs. This study used a one-factor randomized block design with4 levels of treatment of activator, K0 = control, K1 = chopped midribs+cow manure fertilizer, K2 =chopped midribs+EM4, K3 = chopped midribs+cow manure fertilizer+EM4) with three replications.Data were analyzed with ANOVA and continued with DMRT test at 5% level if the F test showed areal effect. The results showed that the K2 with treatment chopped salak Sidimpuan leaf midrib andEM4 activator tended to give the best results in reducing the levels of C-organic and C/N ratio aswell as increasing total Nitrogen, total phosphorus and total potassium after composting comparedto other activator delivery treatments.

Abstract

Maize is important food comodity in indonesia beside rice. In its devolepment,maize does not only  function as food for human, but also asa staple in animal feed industry and other needs, to meet market demand for increased maize production,it is in necessary to improve  cultivation methods with the application of growth regulators,namely by used giberellin and cytokinins.Giberellin is hormone that affects plant growth in the germination and flowering phases while cytokinins play arole in cell elongation. The aim of this study was to evaluate the effect of gibberelin and cytokinins on stem height, leaf lenght  panicle land.This study used a completely randomized design with two factors, the concentration of giberellin and cytokinin 0, 10,20,50 ppm.Based on the data analysis below combiation had a significant effect on the stem height(P2C1).Cytokinin at concentration  of 25 and giberelin  10 ppm  increase the stem height(. The combination cytokynin 50 ppm and giberellin 50 ppm  (P3C3) affect  leaf  lenght and lengt of panicle maize.

Abstract

Tomato plant (Solanum Lycopersicum L.) is one of the horticultural commodities that have the potential to be developed because it has quite high economic value. One of the efforts made to increase the growth of tomato plants is by using organic fertilizers. Organic fertilizer is the best and natural soil repairer than artificial/synthetic. This study aims to determine the response of tomato plant growth to organic fertilizer by observing plant height, the number of leaves, and stem diameter. This study used an experimental method with a randomized block design consisting of 4 treatments, namely compost, manure, and green manure. The results of the observations were analyzed using Analysis of Variance (ANOVA) and statistical data processing was performed using the F test at the level of α = 5%. The results showed that the growth of tomato plants for the highest plant measurement, the highest average number of leaves, and stem diameter were found in the compost (PK) treatment.
