ABSTRACT The objective of this work was to evaluate the effect of temperature and substrate on the germination of P. volubilis seeds. Seeds harvested from 25 matrix plants were submitted, in two studies, to conditions of (i) sowing in rolled paper towel at the temperatures of 10, 15, 20, 25, 30, 35, 40, and 45 °C, for the evaluation of germination, first count of germination, germination speed index and mean time for germination, and (ii) sowing in the substrates paper towel, sand, Bioplant®, Bioplant® and micron, superfine, fine, medium and coarse vermiculite. The same evaluations mentioned in the first study were conducted at the temperature of 30 oC, as well as plant growth. The treatment replicates were distributed in a completely randomized block design and the effects of temperature were compared by polynomial regression analysis. The substrates were compared by the Scott-Knott test at 0.05 probability level. The data show that the ideal range of temperature for the germination of P. volubilis is between 25 and 30 °C. The temperature of 20 °C is the minimum for germination and those above 35 °C are lethal to these seeds. The most favorable substrate for P. volubilis seed germination is micron or fine vermiculite.

The success of the corn agro-industry is greatly influenced by fertilizeravailability. A notable effort to support that situation is to increase compost production through the utilization and processing of beef cattle and corn wastes. Thisresearch proposed to produce compost from the utilization of beef cattle and corn wastes by following the Indonesian National Standard (SNI). The composting process was carried out by preparing several materials consisting of beef cattle manure (BCM), wet/dry stover (WS/DS), and EM4 solution. These materials were fermented anaerobically, then checked and stirred every three days.The fermentation was stopped after 40 days. This study used a Randomized Block Design (RBD) consisting of five levels of compost materials treatments, namely P0, P1, P2, P3, and P4, with three replications. The parameters observed were the characteristics of cattle and corn waste, the physical feature of the compost, and the nutrient content of the compost (yield, water content, pH, P2O5, K2O, organic C, total N, and C/N ratio). P2 treatment (BCM:WS:DS:EM4 =1:2:1:1) produced compost with the best characteristics, namely blackish brown color and crumbly with slightly sour aroma. The yield obtained was 32.95%, water content was 10.08%, pH was 5.59, P2O5was 0.50%, K2O 1.26%, organic C was 52.34%, total N was 1.34% and C/N ratio was 39.06. These characteristics are by following under the SNI cheap, practical in manufacture and application in the field, and environmentally friendly.

The objective of this study was to assess the long-term effects of feeding a diet with no mineral phosphorus (P) supplementation on performance and P excretion in high-yielding dairy cows. In exp. 1, 24 primiparous (PP) and 40 multiparous (MP) Holstein cows were allocated to one of two treatments at calving: (1) regular corn silage and alfalfa haylage based milking cow total mixed ration (TMR; 0.42% P diet) or (2) milking cow total mixed ration (TMR) without supplemental mineral P (0.35% P diet) in a completely randomized design. The trial lasted until after two lactations were completed or the cow was culled. In exp. 2, eight MP Holstein cows (108 ± 8.0 d in milk) were used to determine P digestibility and retention in a completely randomized block design. In exp. 1, the 0.35% P diet cows had lower body weight, body condition score and milk urea nitrogen and higher faecal P than the 0.42% P cows. The dry matter intake (DMI) of PP cows on the 0.35% P diet was lower than that of PP cows on the 0.42% P diet. There was no difference in the DMI of MP cows. The P intake of 0.35% P diet PP cows was 30% lower than that of 0.42% P diet PP cows. The P intake of 0.35% P diet MP cows was 20% lower than that of 0.42% P diet MP. The digestibility coefficient of P for the 0.35% P diet was higher than that for the 0.42% P diet. These results suggest that the forages used in the present study contained adequate amounts of P to sustain milk production in high-yielding MP cows. However, for PP cows some mineral P supplementation is recommended especially during early lactation. Key words: Phosphorus, environmental pollution, intensive dairy operations

The okra grows well in hot weather, finding favorable conditions for development in Brazil. We evaluated the production of okra seedlings and productivity. The experiment was conducted in the experimental area of the State University of Mato Grosso do Sul, in Aquidauana. In the seedling phase we tested substrates (100% triturated cassava stems, 75% triturated cassava stems and 25% vermiculite, 50% triturated cassava stems and 50% vermiculite, 25% triturated cassava stems and 75% vermiculite and 100% vermiculite). These substrates were placed in two protected environments (nursery with black screen, 50% of shading, and aluminized screen, 50% of shading). Each environment was considered an experiment conducted in completely randomized design with eight replications. After that we realized joint analysis. In the field, a total of 10 treatments generated from combinations of environments and substrates (2 environments x 5 substrates) were distributed in a randomized block design with four replications. The average proportions of cassava stems and vermiculite may be suitable for okra seedlings. The results of shoot and total dry phytomass indicate that the aluminized screen can be recommended for okra seedlings production when the substrate with a 1:1 ratio is used. Seedlings grown on higher percentages of vermiculite anticipate production, while seedlings produced only in cassava stems tend to slow it down. The aluminized screen tends to increase the yield of okra seedlings. Average proportions of vermiculite and cassava stems for seedling production under aluminized screen, provide more fruits and yield of okra in Aquidauana.

Winged bean (Fabaceae) is a tropical crop that has high nutrient content, and almost all parts of the plant are edible. The research aimed to evaluate the growth and production of winged bean in an intercropping system with tomato. The study was conducted at the Cikabayan Experimental Field of Bogor Agricultural University, Bogor, Indonesia, in a randomized block design with three replications during the rainy season of December 2017 to June 2018. Winged beans were planted in high and low population densities and intercropped with three tomato genotypes, “Tora”, F70030081-12-16-3 and “Apel Belgia”. Monoculture winged bean was assigned as control. Tomatoes were planted between the rows of the winged beans in the intercropping treatment. The results showed that the growth of winged bean in monoculture and intercropping systems was not significantly different. The photosynthetic activity of winged bean at three to five weeks after planting remained high, indicating that the vegetative growth was optimal in both systems. Intercropping increased the winged bean number of pods per plant by 12.66-19.52% compared to monoculture, irrespective of population density. Therefore, winged bean could be considered as suitable to grow in intercropping systems.

Cocoa pod husk is a by-product of cocoa processing which is quite abundant and has not been used optimally. Cacao pod husk can be used more optimally by extracting, its content of polyphenol compounds which can be used as natural antioxidants. The aim of this study were to determine the effect of temperature and maceration time of cocoa pod husk extract as a source of antioxidants and to determine the best type of temperature and maceration time to produce cocoa pod husk extract as a source of antioxidants. This experiment was designed by using factorial randomized block design. The first factor was type of maceration temperature consisting of 30±2°C, 45±2°C and 60±2°C. The second factor was maceration time, which were done for 24, 36 and 48 h. The data were analyzed with analysis of variance and continued with the Tukey test. The results showed that the temperature and time of maceration had a very significant effect on yield, total phenolic and antioxidant capacity of cocoa pod husk extract. Interactions between treatments had a very significant effect on total phenolic and antioxidant capacity but did not significantly affect the yield of cocoa pod husk extract. The best treatment for producing cocoa pod husk extract as a source of antioxidants was using maceration temperature 60±2°C and maceration time for 36 h with yield characteristics 5,28±0,15%, total phenolic at 168.16±0,06 mg GAE/g and capacity antioxidant 130.94±0.84 mg GAEAC/g.
