This study aims to see a picture of empathy by integrating biological, sociological and psychological by using a delayed broadcast application which is intended to help Guidance and Counseling students to increase empathy and communication skills through a biopsychosocial approach to identify counselee problems. The implementation study uses a formative evaluation framework to see the counselor's communication with the counselee through three stages; 1) evaluation, consisting of a conceptual review; 2) technical, both formal and informal by the lecturer; 3) evaluation of Guidance and Counseling students who are involved in surveys and observations. The findings of this study indicate that bio-psycho-social video delays can improve counseling communication techniques (empathy) for prospective counselors. The results of this study can be used as a reference for lecturers and prospective counselors in providing learning about the counseling process so as to improve the quality of prospective counselors, especially in increasing empathy which is one of the counselor's character competencies.

Abstract Field trials were conducted in 2016 and 2017 at the Southwest Purdue Agricultural Center in Vincennes, IN to determine the tolerance of plasticulture-grown ‘Fascination’ triploid watermelon to flumioxazin. Treatments were applied after plastic was laid, but one day prior to transplanting and consisted of row middle applications of clomazone (210 g ai ha−1) plus ethafluralin (672 g ai ha−1), flumioxazin (107 g ai ha−1), and flumioxazin (88 g ha−1) plus pyroxasulfone (112 g ai ha−1), a broadcast application of flumioxazin (107 g ha−1), and a non-treated check. Compared to the non-treated check, the broadcast application of flumioxazin reduced watermelon vine length and normalized difference vegetation index (NDVI) values. All other herbicide treatments had vine length and NDVI values similar to the non-treated check. At 25/26 d after transplanting (DAP), weedy ground cover in row middles of the non-treated check was 39% and 14% in 2016 and 2017, respectively. Weedy ground cover in herbicide-containing treatments was significantly less, ≤7% and ≤5% in 2016 and 2017, respectively. Marketable watermelon yield of the non-treated check was 77,931 kg and 11,115 fruits ha−1. The broadcast application of flumioxazin resulted in reduced marketable yield (64,894 kg ha−1) and fewer fruit (9,550 ha−1).

This research concerns the impact of the live broadcast application use in online learning during the Covid-19 Pandemic. This study aims to determine the impact of the live broadcast application in online learning during the Covid-19 pandemic. The problem essence in this study is the processes, constraints, and variations in applying the live broadcast application to online learning during the Covid-19 pandemic. This study applied a qualitative study type. The participants in this study were students of the Indonesian Language and Literature department in the Faculty of Languages and Literature, Universitas Negeri Makassar, Indonesia, in 2019-2020. This study found that the learning media used in the teaching and learning process for a regular meeting during the Covid-19 pandemic as live broadcast application were Zoom, Google Meet, and Streamyard. However, students also experienced that some lecturers only used live broadcast for online examination regarding evaluating the students’ assignment progress submitted to Google Classroom. Students also reported that lecturers use live broadcast applications to teach and other applications, such as Google Classroom and LMS. This study also found out the constraints experienced by students regarding the learning process during the Covid-19 pandemic. This study revealed that the students experienced some constraints in the learning process during the Covid-19 pandemic, such as a large amount of data or quotas in use, the inadequate time provided by media of live broadcast, which is up to about forty minutes. Also, unsupportive signals always make weak audio sounds and sometimes close the application, making it difficult for students to comprehend the materials. Therefore, this study recommends that the lecturers maximize the teaching and learning process to anticipate time, place, and internet data packages as students’ constraints by recording the live broadcast in the form of YouTube live streaming.

Ensuring sustainable agricultural production technologies is becoming increasingly important in the face of the observed climate change and need to reduce the harmful environmental impact of agriculture. The aim of the study is a comparative assessment of the deep fertilizer placement method with surface broadcast application of fertilizers as regards overall sustainability. To reach this goal, based on the results of field experiments and expert opinions, the values of sustainability indicators (economic, environmental and social aspects) were determined. The AHP (analytical hierarchy process) method was applied to comparative assessment. The conducted analysis showed that economic, environmental and overall sustainability assessment are conditioned by productivity achieved. In the first year of the experiment, when the yield increase was not achieved, in terms of sustainability criteria considered, the surface broadcast application of fertilizers was determined to be preferred as compared to the deep fertilizer placement method. On the other hand, in the second year of research with yield increase, the practice with the deep application of mineral fertilizers resulted in a better performance than surface broadcast fertilization, while showing a similar overall performance in the case of natural fertilizers.

The common bean (Phaseolus vulgaris L.) requires nitrogen (N) during its vegetative and reproductive stages. A single application of a blend of polymer-sulfur coated urea (PSCU) and conventional urea (U) treated with NBPT (N-(n-butyl) thiophosphoric triamide) can meet that demand. Broadcast application could improve yield than other N management practices. This research evaluated two blends (70%PSCU + 30%U and 30%PSCU + 70%U) and three N fertilization managements (incorporated, broadcast, and split application) on soil ammonia volatilization (AV) and N mineral content (NM); plant N uptake (NU) and 15N recovery from U (NUR); and yield (GY). Irrigated field experiments were conducted in 2018 and 2019 in Rhodic Eutrustox soil. The N application rate was 90 kg ha−1. AV reached 12% (30%PSCU + 70%U, broadcast application) and 14% of the applied N (split application at the third trifoliate leaf unfolded stage (V4)). The incorporated application resulted in higher NM in the vegetative and reproductive stages than the other management practices. Broadcast application resulted in higher NU than split application at physiological maturity. Split application resulted in higher NUR (grain) and GY than broadcast application. There was a positive correlation between NUR (grain) and GY in all N fertilization management treatments. The NUR values reached 48% (30%PSCU + 70%U) and 18% (70%PSCU + 30%U). Split N application using these blends can improve NUR in grain and GY compared to broadcast application in Rhodic Eutrustox soil. This information can help farmers improve the fertilization management practices used with these blends, and thereby avoid economic losses and environmental pollution.

The effects of the dose and application method of limestone - broadcast or in furrow - and of agricultural gypsum on soil fertility, the control of clubroot, and cauliflower development in mountain farming areas were evaluated. Initially, four doses of broadcast limestone (0.0, 1.0, 2.0, and 4.0 Mg ha-1) and two cauliflower cultivars (Sharon and Piracicaba Precoce) were analyzed. A second experiment evaluated limestone (4.0 Mg ha-1) application treatments: broadcast and in furrow, broadcast limestone + gypsum (3.0 + 1.0 Mg ha-1), and broadcast gypsum (1.0 Mg ha-1). Soil fertility was improved, and significant increases were observed in the total and healthy root volume with increasing doses of limestone. With 4.0 Mg ha-1, a 58 and 85% increase in yield was observed in Sharon and Piracicaba, respectively, compared to the control. Treatments with limestone and limestone + gypsum, regardless of the application method, elevated pH (≥ 10%), base saturation (V%) (≥ 37%), and calcium (Ca) contents (≥ 100%), and reduced the levels of aluminum ions (Al3+) (≥ 60%) and clubroot severity (≥ 64%) and favored biomass accumulation (≥ 27%) and yield (≥ 9.2%). The application of limestone in the furrow yielded results similar to the broadcast application.

Polymer coated urea (PCU) have the potential to increase nitrogen (N) use efficiency (NUE) by the release of N following crop demand while reducing losses by volatilization, leaching and denitrification. However, the NUE of PCU is still unclear especially in systems of corn-palisadegrass intercropping. Broadcast application of urea result in ammonia volatilization losses, new technologies must be adopted in order to allow broadcast application of urea. The aim of this research was to evaluate NUE from PCU in the corn-palisadegrass intercropping system and the viability of the broadcast application using PCU. Two field trials were carried out in a 4 × 2 factorial design including fertilization treatments and application forms. Fertilization treatments were: Conventional Urea topdressing (CUT); Conventional Urea at corn planting (CUP); PCU applied at planting to release in 30 days (PCU30); PCU mixture applied at planting to release in 30 and 60 days (PCU30+60); and application forms: broadcast placement and in furrow. 15N-urea was used for the determination of NUE. The corn yield and palisadegrass above-ground biomass were not affected by the fertilization treatments or application forms. PCU did not increase N uptake and the NUE by corn or palisadegrass in relation to urea. The N uptake from fertilizer by palisadegrass intercropped with corn is less than 1% of all N uptake on the intercropping system and at most 2% of the N fertilizer applied. The slow release urea does not enable the broadcast application and its efficiency depended upon the same climatic conditions as those of the conventional urea.

Brazil southern region edaphoclimatic conditions allow farmers to grow perennial winter legumes. However, at summer, a seasonality occurs in the production of these species allowing the grown of annual crops such as corn. In this way, interference between white clover (Trifolium repens L.) living mulch and corn crop (Zea mays L.) was studied using a clover sward established after one and two growing season in relation to the usual system of corn grown over black oat straw aiming to study the relationships occurring in this intercrop, such as white clover herbicide suppression, competition and its nitrogen effects on corn yield as well as its potential to became perennial after corn harvest. White clover suppression management was established in the main plots and corn nitrogen fertilization (0, 60, 120, 180 kg ha-1) was performed in the subplots (4.2 × 8 m) in a randomized block design with four replications. White clover suppression managements were: (i) partial suppression achieved by mowing the plots at the corn seeding day; (ii) partial suppression achieved by mowing plus chemically broadcast application of 2.4-D; (iii) partial suppression achieved by a chemically broadcast application of glyphosate. Corn grain yields ranged from 3.0 to 12.2 Mg ha-1. Nitrogen input and herbicide management are important elements to reduce white clover competition and increase corn yield. It is possible to manage white clover as living mulch in corn with its full recovery after corn harvest without replanting. Clover with 1 cycle is easier suppressed than perennial clover sward and can be handled in intercropping with corn without affecting grain yield, with ability to resume growth in the next growing season.
