Subject: Bibliometric and social network analysis in scientific research on precision agriculture
Keywords: Bibliometrics, precision agriculture, research collaboration, scientific analysis, social network.
Abstract: Precision agriculture (PA) is used to improve agricultural processes. A better understanding of PA as well as the evolution of the research status through the available literature are reported and discussed in this study. The Web of Science (WoS) was used to obtain the research records under study. Indicators of scientific productivity, collaboration between countries and research impact were evaluated through a social network analysis. The keywords included in the publications and subject areas under which the research was published were also evaluated through subject analysis. A total of 2027 articles were analysed from 1994 to 2014. The most productive journals were ‘Computers and Electronics in Agriculture’ (n = 191) and ‘Precision Agriculture’ (n = 110). The
most frequent keywords were management’ (n = 243), ‘yield’ (n = 231), ‘soil’ (n = 198) and ‘variability’ (n = 190). The collaboration network showed the United States occupying a central position, in combination with some leading countries such as Brazil, Germany, People’s Republic
of China, Canada, Australia and Spain. A steady increase in PA research was identified during the last decade, which was even more sharp between 2010 and 2014. The increased importance of PA
research has recently led to the birth of specific journals such as Precision Agriculture. The increasing number of journals that publish articles related to the topics included in the WoS must also be considered. The network analysis identified a number of developed countries in the hotspot of international collaboration.

Subject: Periodic table of elements revisited for accommodating elements of future years
Keywords: Atomic numbers, atomic structure, inner orbitals, periodic table.
Abstract: The periodic table of elements shows only three columns and two separate rows for lanthanides and actinides called lanthanide and actinide series respectively. The newly discovered elements have already occupied the last row and last column of the table, which has the electronic orbital configuration, 7s2 5f14 6d10 7p6
. After the discovery of two more new elements with atomic numbers 119
and 120, the third new element with atomic number 121, will have to be entered in the g-block series, according to the electronic orbital configuration theory, 7s2 5f14 6d10 7p6 8s2 5g1 . Thus, in the present periodic table, such new g-series has to be written separately below the actinide series.
Such a representation of elements would be quite confusing. Therefore, to avoid this and also to ensure the visibility of the ‘concept of inner orbitals liked, f, g, etc.’, a new and expanded form of the periodic table has been designed. This table is expected to accommodate all the new elements
of higher atomic numbers and also give instant information on the electronic orbital structure of an element.

Abstract: Cultivated plants have evolved from their
close wild relatives through thousands of
years of evolution and selection. Crop
wild relatives (CWRs) are taxa closely
related to crop plants and form an important source for incorporation of useful traits like biotic and abiotic stress tolerance, which are critical for food and nutritional security and environmental sustainability. Over 167 crops and about 320 high priority CWRs are believed to have originated in India, which has been designated as the Hindustani Centre of Origin and Diversity by
Vavilov. India is the primary centre of
origin of rice, sugarcane, green gram,

Subject: Biological suppression of coconut black headed caterpillar Opisina arenosella outbreak in East Godavari district of Andhra Pradesh – eco friendly technology
Keywords: Biological control, coconut, Opisina arenosella, outbreak, parasitoid
Abstract: The leaf eating black headed caterpillar Opisina arenosella is a serious pest of coconut palm causing significant yield loss in all the coconut growing tracts of India. During 2015–16, a high infestation of black
headed caterpillar was observed in all the coastal districts of Andhra Pradesh, and an incidence ranging from 42.82% to 62.86% was recorded. From October 2015 to April 2016 inundative releases of about
3,788,000 larval parasitoids Bracon hebetor and Goniozus nephantidis were carried out in pest affected gardens in Allavaram and Uppalaguptam mandals of East Godavari. To study the impact of the parasitoid
releases, 10 leaflets/palm were randomly collected from 10 sample gardens in seven villages of these mandals and the pest population recorded. After three months of parasitoid release, the larval population of
O. arenosella decreased by 34.08–75.88%, pupal population by 33.33–94.52%, and the paralysed larval population recovered was 8.30–26.92%. After six months,
the larval population decreased by 59.65–100%, the pupal population up to 92.77–100% and the paralysed larval population recovery was also high, ranging from 18.68% to 34.61%. The impact of inundative
release of bio agents for suppression of leaf eating caterpillar was prominent, after six months providing impetus to the role of biological control in pest management. The assumed overall economic loss prevented
due to this intervention was 192.6 million rupees.

Keywords: Anabas testudineus, butylated hydroxyanisole, endocrine disruption
Abstract: Fish short-term reproductive assay (FSTRA) is a tier one assay for screening the endocrine disrupting property of a compound. This study analysed the end
points like variations in Gonado–Somatic index (GSI), sperm quality and count, serum hormone levels (FSH, LH, estrogen and testosterone) to study the endocrine
disrupting properties of butylated hydroxyanisole (BHA). A fresh water teleost, Anabas testudineus was used as animal model in this study. LC50 value of BHA was 250 mg/kg body weight in fish. Effects of
four different doses of BHA were studied – 2, 5, 50 and 75 mg/kg body weight. BHA is found toxic at high doses of 250 mg/kg body weight and above. All the four doses of BHA caused significant impact on GSI,
sperm count and quality. Serum hormone assay by ELISA showed significant variations in treated groups compared to control group.

Subject: Bank material characteristics and its impact on river bank erosion, West Tripura district, Tripura, North-East India
Keywords: Bank erosion, bank material, grain size, shear strength, West Tripura district.
Abstract: In West Tripura district, river bank erosion becomes very common during monsoons along the Haora River and the Sonai Gang. Erosion occurs across 45.39 km (96% of the total length) of the Haora River and 20.12 km (90% of the total length) along the Sonai Gang. The main cause of river bank erosion in the district is the nature of bank material with respect to its erodibility factor (resisting force). The objectives of this study were to identify the nature of bank material
of the rivers in West Tripura district and to analyse the shear strength of these materials. Samples were collected from twelve sites at various depths from top
of the river bank up to the water level. Hydrometer test and grain size were also analysed. Uniformity coefficient (Cu) and coefficient of curvature (Cc) were calculated to identify the shear strength of bank soil.
Tests revealed that the bank soils contain more than 90% sand and less percentage of silt and clay. This makes the soil non-cohesive and leads to maximum erosion.

Subject: Ground surface warming in peninsular India: evidence from geothermal records
Keywords: Borehole temperatures, ground temperature history, peninsular India, surface air temperature.
Abstract: Analyses of borehole temperature profiles provide useful information about regional climate change over a few centuries. Data from 146 borehole sites in the crystalline terrain of peninsular India were used to reconstruct surface ground temperature history. Depths of the boreholes ranged from 150 to 1522 m. The temperature profiles were characteristic of heat flow by conduction, being largely unaffected by perturbations due to groundwater flow. The profiles show temperature anomalies in the top few hundred meters that is consistent with changing surface temperature over the past two–three centuries. Analysis of individual profiles for a ramp change in temperature reveals predominant surface ground warming in peninsular India with a mean magnitude of 1.0 ± 0.2°C for 129 ±18 years at 95% confidence level corresponding to onset ca 1860 AD for the change.

Abstract: Peach trees were trained to four systems, viz. Y-shaped, Hedge row, Espalier and V trellis. Irrespective of the training system in upper canopy total PAR increased from January to July and then a decrease
was recorded. However, in lower canopy an inverse trend was recorded. The total radiation intercepted during the year was maximum (59.99%) in Espalier system followed by V trellis (57.76%). Minimum
radiation interception (49.05%) was recorded in trees trained to Hedge row. Upper canopy part of the tree received more PAR which influenced fruit quality in
terms of size, weight, acidity, total sugars, firmness.

Abstract: Studies were undertaken for two consecutive years (kharif 2015 and 2016) at the CSK Himachal Pradesh Krishi Vishvidyalaya, Rice and Wheat Research
Centre, Malan (Himachal Pradesh, India) under field conditions using paddy variety ‘Kasturi Basmati’. Losses in paddy due to rice hispa, Dicladispa armigera (Oliver) were quantified in terms of release density (number of adults per tiller) and phenological stages of crop. Results revealed that both these aspects significantly influenced leaf damage as well as yield of paddy. Early-stage release (20 DAT, days after transplanting) contributed to maximum leaf damage (69.9 PLDI (per cent leaf damage index)) and at the same time exerted a significant negative influence on various yield components, viz. number of tillers, panicles, grains and grain weight (g) for which the respective regression coefficients were 5.82, 5.73, 441.4 and 8.06, respectively (per 4 rice hills).

Abstract: Market economy is mainly characterized by private property. For entrepreneurs, private property allows action according to market realities, opportunities and strategies aimed to succeed. There is no doubt that all
small and medium enterprise (SME) achievements are closely linked to profitability, as SMEs constitute a development engine that fuel country GDP. We examine the profitability implications of providing finance to 1233 Romanian SMEs during 2004–2008 based on financial structure ratios. In addition, we analyse the correlation between various return rates.
We establish a correlation between performance and equilibrium of Romanian SMEs in five economic sectors: pharmaceutical, furniture manufacturers, leather garment, software and textiles.

Keywords: Anthropogenic stressors, bacterial communities, metagenomics, microbial ecology, pollution
Abstract: The microbial communities of mangroves which form important links in elemental cycling and bioremediation have not been elucidated in most parts of the world. Due to urbanization and deforestation mangroves are also under threat. In the present study, high throughput next generation sequencing technology, based on 16S rRNA amplicon analysis using
Illumina platform was employed to unravel the microbial diversity present in different mangrove areas in the west coast of India. It could be seen that in mangroves, Proteobacteria and Bacteroidetes were
most common, followed by taxon such as Firmicutes, Spirochaetes, Chloroflexi and Verrucomicrobia. In proteobacteria group, Gammaproteobacteria, alphaproteobacterial and Deltaproteobacteria were most abundant. Interestingly, bacteria having the capacity
to utilize sulphate were present along with methanogens in all samples, suggesting that anaerobic and sulphur-based metabolic pathways play an important role in these mangrove ecosystems. The differences in
bacterial diversity can be partly attributed to biotic and abiotic factors such as physico-chemical characteristics of the samples, geographical location and
natural and human-induced changes in the locality. The metagenomics analysis of mangrove sediment samples has helped in elucidating the baseline data on bacterial diversity along mangroves in Maharashtra

Subject: Bacillus amyloliquefaciens (VB7) with diverse antimicrobial peptide genes: A potential antagonist for the management of fairy ring spot in carnations
Keywords: Antimicrobial peptide, Bacillus amyloliquefaciens (VB7), Cladosporium echinulatum, fairy ring spot.
Abstract: Fairy ring spot incited by Cladosporium echinulatum is an unexplored yet disastrous disease of carnation. Bacillus myloliquefaciens (VB7) with 10 diverse
antimicrobial peptide genes, effectively reduced fairy ring spot intensity to 6.44 (per cent disease index, PDI) and increased flower yield (196.61 Nos/m2) compared to control (PDI – 60.33; flower yield – 140.70 Nos/m2). Plants treated with tebuconazole (250 EC, emulsifiable concentrate) and alternated with mancozeb (75% WP, wettable powder) were much effective and reduced disease intensity up to 3.46 PDI.
However, flower yield was comparatively lesser to the treatment of B. myloliquefaciens (VB7). Results revealed that B. amyloliquefaciens out-performed fungicides in growth promotion.
