Abstract The objective of this work was to evaluate the effect of different compositions of renewable substrates and seasons of the year on the quality of Piptocarpha angustifolia clonal plants. The experiment was carried out in a completely randomized design in a 4x6 factorial arrangement (four seasons x six substrate compositions). The analyzed substrates were: S1, commercial substrate with pine bark and coconut fiber base (CF); S2, carbonized rice husk (CRH); S3, fibrous and grainy CF; S4, 50% CF and 50% CRH; S5, 30% CF and 70% CRH; and S6, 70% CF and 30% CRH. Minicuttings of 8±1 cm were planted in tubes of 110 cm3 and placed in a greenhouse, during the four seasons of the year. The evaluated variables were: survival and number of roots at 70 days; survival and emission of shoots at 100 days; rooting, shoot height, stem diameter, and their ratios; easiness of removal from tubes; aggregation to the substrate; and multiplication rate at 130 days. The highest CRH/CF ratio favored the development of better-quality plants, and S5 was the most adequate substrate. Spring is more favorable to the survival and quality of cuttings, and, together with summer, favors the highest multiplication rates. The S5 substrate has better physical and chemical quality and improves P. angustifolia clonal plants.

The method for determining the appropriate time to harvest banana could affect the shelf life and quality of banana fruits during storage. The objectives of this study were to establish the heat unit as harvesting criteria of banana “Mas Kirana” and to evaluate how heat unit affects fruit shelf life and postharvest maturity characteristics. The research was conducted at PTPN VIII Parakansalak Plantation, Sukabumi, West Java, Indonesia, in November 2017 to February 2018. Laboratory analysis was conducted in Postharvest Laboratory, Department of Agronomy and Horticulture IPB in February to April 2018. The experiment was organized in a completely randomized design with a single factor of eight different flower tagging times after anthesis. Each treatment was replicated five times totaling 40 experimental units. The results showed that the different times of anthesis did not affect fruit size, weight per hand, number of fruits per hand and weight per fruit. Different time of anthesis did not affect respiration rate, fruit shelf life, physical and chemical quality. The minimum heat unit of 650ºC degree days can be used as harvesting criteria for banana “Mas Kirana”. The number of day after anthesis was 39 to 43 with fruit shelf life of 12 to 16 days.

In this study, we evaluated the effects of fertigation with domestic sewage effluent and different substrates on the growth of Caraíba seedlings (Tabebuia aurea Benth). The experiment was accomplished in a greenhouse in Mossoró, RN. Five irrigation solutions (100% of water supply - WS, 100% of domestic sewage effluent – DS and dilutions of 75% DS + 25% WS, 50% DS + 50% WS e 25% DS + 75% WS) were tested and two substrates (75% soil + 25% bovine manure and 75% soil + 25% coconut fiber) using completely randomized design in subdivided plots with three replicates per treatment. Growth and development parameters were measured at 30, 60, 90, and 150 days after cultivation. The variables shoot height, collar diameter, height/diameter ratio, dry matter of root, shoot and total (root and shoot), shoot/root ratio, Dickson quality index, and nutritional evaluation of nitrogen, phosphorus, potassium and calcium were determinate. We verified that the use of domestic sewage increased growth and quality of caraíba seedlings, besides promoting nutrient accumulation in the plants grown in substrate of bovine manure plus soil with 100% application of domestic sewage in the fertigation.

<p class="Abstrak"><span lang="EN-GB">By processing sorghum grains into flour, the use of sorghum grains to support food diversification can be made more varied. The research objective was to determine the physical and chemical properties of sorghum muffins and changes of physical properties of sorghum muffins during storage. The research uses a completely randomized design with two factor, grain soaking duration (hours) and ratio of concentration of whole sorghum flours with gluten flour (%) and consists of nine treatments combination. The result shows that treatment has a significant effect on the power expansion, degree of brightness, fat, and preference for organoleptic properties. The best treatment was 24-hours of soaking, 25% whole sorghum flour, 75% gluten flour that produces expanded power at 138,83%, degree of brightness (L) at 67.03, redness (a) at +4.33, yellowness (b) at +27.37, water content of 12.59%, protein content of 6.95%, fat content of 2.46%, score of color at 3.20, texture score at 3.13, aroma score at 3.16, taste score at 3.24, and for overall acceptance at 3.53 (like). Changes of physical properties of sorghum muffins during storage for 3 days can be explained with the linear equation. For all parameter (weight loss, volume loss, brightness loss), the value of constant a in the equation of sorghum muffin was lower than control muffin that indicated quality loss of sorghum muffins is higher than control muffin. Increasing the concentration of sorghum flour resulted a decrease in the quality of the muffins. The soaking treatment of the seeds in making sorghum flour can maintain the quality of the muffin.</span></p>

               Natural or local yeasts are microorganisms from natural ingredients obtained from fermentation without the need for artificial additives. The objectives of the present study were 1.) to evaluate the physical quality of potato doughnuts produced from the local yeast derived from residue of red fermented palm sap, 2) to obtain the best treatment from the use of local yeast in making doughnuts. In the fermentation process, yeast converts sugar and carbohydrates in the dough into carbon dioxide gas (CO2) and alcohol. Doughnuts are made from wheat flour, but the addition of potato paste can improve the texture so that it is softer and tender due to the interaction between gelatinized starch and gluten but can reduce its swelling power.             The experiment was designed using a completely randomized design (CRD) with three treatments and five replications to produce 15 experimental units. The treatments were a) Control (commercial yeast); b) Wheat flour: potato paste: local yeast; 2:1:1; c) Wheat flour: potato paste: local yeast; 2:1:2 and d) Wheat flour: potato paste: local yeast; 2:1:3. The results showed that the best treatment formula was obtained in the treatment B (wheat flour: potato paste: local yeast; 2:1:1) with 20,6% moisture content,  2,09% protein content and 3,644 color value (very like), 3,800 taste value (very like) and texture/tenderness with a value of 1032,500.

Morphological and Radical Parameters Associated with the Seedlings Quality of Anadenanthera peregrina (L.) Speg.in Different Substrates. In this research, we evaluated the effects of different substrate formulations on the quality of angico-vermelho seedlings (Anadenanthera peregrina (L.) Speg). The tested substrates corresponded to eight different formulations: Bioplant®, Carolina Soil, Coffee husk, Coconut fiber and Vermiculite. In the nursery phase, the following were evaluated: height of the aerial part (H); neck diameter (D); fresh and dry biomass of the aerial parts and radical system; dickson quality index (IQD); number of roots regenerated in tubes; and length of roots regenerated in boxes. In the field phase, the following were evaluated: survival; crown diameter; number of lateral roots; and length of the pivoting root. To produce seedlings, a completely randomized design with eight treatments and four replications was used, and for the evaluation of the root regeneration potential (P.R.R.), six replications were used. In the field, the experimental arrangement consisted of subdivided plots, arranged in randomized blocks with four replications. Seedlings with higher averages for most of the evaluated characteristics were produced in the formulation of substrate containing 50% Bioplant® + 30% coffee husk + 20% coconut fiber. The values related to the IQD were positively related to the substrate formulations containing Bioplant®, coffee husk and coconut fiber, which were also positively associated with P.R.R. The substrate formulations containing Bioplant®, coffee husk and coconut fiber resulted in seedlings with a higher P.R.R., evaluated in boxes. Substrates containing Bioplant®, Carolina Soil, coffee husk and coconut fiberfavored the production of seedlings with a better radical system and, consequently, better in the field.
