Abstract
One of the factors responsible for the low soybean yield in Indonesia is low seed quality. Harvesting at the right time is an appropriate method for obtaining quality soybean seeds. ...Furthermore, harvest age can directly influence the physiological quality of seeds. This research aims to determine the effect of harvest time on the Detap-1 variety soybean seed quality. The experimental design was a randomized block (RBD) with variations in harvest time (R7, R8, R8 + 3, R8 + 6, R8 + 9, R8 + 12 days) as a factor. The observed data were then analyzed with the F test and the DNMRT test at a significance level of 5%. In addition, the variables observed were moisture content at harvest, seed germination and vigour, growth speed, the weight of 100 seeds and weight of seeds per pod. The results showed that the best quality seeds of soybean Detap-1 variety were obtained in the treatment where the harvest was in the R8 + 3-day phase.
Abstract
The availability of NPK compound fertilizer is expected to help farmers to optimally supply the nutrient needs of corn plants. The aim of the study was to determine the efficient dose of NPK ...15-15-6-4 fertilizer and its combination with urea on the growth and yield of corn. The study was conducted in Simbang Village, Simbang District, Maros Regency, South Sulawesi in January - April 2019. The study used a Randomized Complete Block Design (RCBD) with a combination of 7 treatments with four replications, consisting of: (P1) 400 kg NPK 15-15-6-4; (P2) 400 kg NPK 15-15-6-4 + 100 kg urea; (P3) 400 kg NPK 15-15-6-4 + 150 kg urea; (P4) 450 kg NPK 15-15-6-4; (P5) 350 kg NPK 15-15-6-4; (P6) 350 kg NPK 15- 15-6-4+ 150 kg urea; (P7) 150 kg NPK Phonska + 250 kg urea. The results showed that NPK 15-15-6-4 compound fertilizer had a good effect on the growth and yield of corn plants. NPK 15-15-6-4 compound fertilizer at a dose of 450 kg/ha and a dose of 400 kg NPK 15-15-6-4 + 100 kg urea gave the best effect with total yield up to 5.5-5.9 ton/ha.
In this Letter, comprehensive results on π±, K±, KS0, p(p¯) and Λ(Λ¯) production at mid-rapidity (0<yCMS<0.5) in p–Pb collisions at sNN=5.02 TeV, measured by the ALICE detector at the LHC, are ...reported. The transverse momentum distributions exhibit a hardening as a function of event multiplicity, which is stronger for heavier particles. This behavior is similar to what has been observed in pp and Pb–Pb collisions at the LHC. The measured pT distributions are compared to d–Au, Au–Au and Pb–Pb results at lower energy and with predictions based on QCD-inspired and hydrodynamic models.

The production of Ξ− and Ω− baryons and their anti-particles in Pb–Pb collisions at sNN=2.76 TeV has been measured using the ALICE detector. The transverse momentum spectra at mid-rapidity (|y|<0.5) ...for charged Ξ and Ω hyperons have been studied in the range 0.6<pT<8.0 GeV/c and 1.2<pT<7.0 GeV/c, respectively, and in several centrality intervals (from the most central 0–10% to the most peripheral 60–80% collisions). These spectra have been compared with the predictions of recent hydrodynamic models. In particular, the Kraków and EPOS models give a satisfactory description of the data, with the latter covering a wider pT range. Mid-rapidity yields, integrated over pT, have been determined. The hyperon-to-pion ratios are similar to those at RHIC: they rise smoothly with centrality up to 〈Npart〉∼150 and saturate thereafter. The enhancements (yields per participant nucleon relative to those in pp collisions) increase both with the strangeness content of the baryon and with centrality, but are less pronounced than at lower energies.

Angular correlations between unidentified charged trigger particles and various species of charged associated particles (unidentified particles, pions, kaons, protons and antiprotons) are measured by ...the ALICE detector in p–Pb collisions at a nucleon–nucleon centre-of-mass energy of 5.02 TeV in the transverse-momentum range 0.3<pT<4 GeV/c. The correlations expressed as associated yield per trigger particle are obtained in the pseudorapidity range |ηlab|<0.8. Fourier coefficients are extracted from the long-range correlations projected onto the azimuthal angle difference and studied as a function of pT and in intervals of event multiplicity. In high-multiplicity events, the second-order coefficient for protons, v2p, is observed to be smaller than that for pions, v2π, up to about pT=2 GeV/c. To reduce correlations due to jets, the per-trigger yield measured in low-multiplicity events is subtracted from that in high-multiplicity events. A two-ridge structure is obtained for all particle species. The Fourier decomposition of this structure shows that the second-order coefficients for pions and kaons are similar. The v2p is found to be smaller at low pT and larger at higher pT than v2π, with a crossing occurring at about 2 GeV/c. This is qualitatively similar to the elliptic-flow pattern observed in heavy-ion collisions. A mass ordering effect at low transverse momenta is consistent with expectations from hydrodynamic model calculations assuming a collectively expanding system.

We have measured the nuclear transparency of the A(e,e'pi+) process in 2H, 12C, 27Al, 63Cu, and 197Au targets. These measurements were performed at the Jefferson Laboratory over a four momentum ...transfer squared range Q2=1.1 to 4.7 (GeV/c)2. The nuclear transparency was extracted as the super-ratio of (sigmaA/sigmaH) from data to a model of pion-electroproduction from nuclei without pi-N final-state interactions. The Q2 and atomic number dependence of the nuclear transparency both show deviations from traditional nuclear physics expectations and are consistent with calculations that include the quantum chromodynamical phenomenon of color transparency.

This study explored the small stories as a narrative analysis of communication e-waste on social media Instagram. The data of this study is mined from the conversation and interaction between the ...ewasteRJ team with their follower. ewasteRJ is a Non-Governmental Organization focusing on campaigning, collecting, and recycling e-waste. Using a narrative study analyzing a small story created by E-wasteRJ, this study finds 42 posts campaigning e-waste collecting and recycling by introducing an e- waste drop box and drop zone. The result shows that small stories on ewasteRJ account can distinguish the narrative stance-taking and rescripting among ewasteRJ and followers participating in the conversation. The story of e-waste is represented by a content post by ewasteRJ as a narrative stance concerning e-waste handling. Dropbox as a central campaign and education in e-waste handling is present in every post. Finally, the story of e-waste in social media is not only the story of the communicator experience itself and all participants in online conversation, especially when the story circulates through related hashtags. It enables a new communicator.
The main problem with biofertilizer is a short storage life. Carrier materials of biofertilizer include determinants of quality and storage life. This study measured the ability of vermicompost to be ...used as a carrier of biofertilizers from various beneficial microbes. The study used a factorial randomized block design with 2 factors and 3 replications. The first factor was the worm and microbial application technique consisting of 4 treatments: no worm; worm applied one week after applying microbes; microbial and worm applications were applied simultaneously and microbes applied one week after applying worm. The second factor was the type of beneficial microbes consisting of 4 treatments: Azospirillum sp; Azotobacter chroococcum; Trichoderma asperellum G strains and Talaromyces pinophilus. The results obtained that after 3 and 6 weeks incubation the highest population was found at T.pinophilus (59.5-210.5×1010 CFU mL−1) and at A. chroococcum (83.5-190.5×1010 CFU mL−1, respectively. After 1 year storage, the population of A.chroococum in the carrier biovermi decreased to 50 - 90×105 CFU mL−1, T. asperellum 60 - 210 ×106 CFU mL−1 and Azospirillum 75×107 - 32×108 CFU mL−1, while T.pinophilus 60 ×106 - 45×108 CFU mL−1.

In this review, we discuss the relationship between environmental crop management and adaptation to warming climates of legume plants and plant breeding, for drought tolerance. The benefits connected ...to the impact of the expansion of appropriate legumes-based agriculture for arid zones are analyzed. We need to two aims to develop programs of breeding and management guided to drought tolerance. The first one is enhancing productivity. The second one is to improve the drought tolerance by mechanisms of water conservation.
We have measured parity-violating asymmetries in elastic electron-proton scattering over the range of momentum transfers 0.12 < or =Q2 < or =1.0 GeV2. These asymmetries, arising from interference of ...the electromagnetic and neutral weak interactions, are sensitive to strange-quark contributions to the currents of the proton. The measurements were made at Jefferson Laboratory using a toroidal spectrometer to detect the recoiling protons from a liquid hydrogen target. The results indicate nonzero, Q2 dependent, strange-quark contributions and provide new information beyond that obtained in previous experiments.
