The presence of mycotoxins in food has been a burning issue and a threat to food security and safety. The global population has sky-rocked continues to be, which has created a challenge of providing quality food to the consumers. Aflatoxins, prevalent in most of the food crops in Nepal as well have posed a risk to national food security. Moreover, the consumption of food products containing mycotoxins is a cause of several health hazards like cancer, gastrointestinal problems, and neuropsychiatric effects. Mycotoxins not only has affected humans but also animals. Prevention, decontamination, and inhibition of absorption of toxins have been done in order to manage and mitigate the effects of mycotoxins. Recent research on mycotoxins is focused on the development of new methods to detect and analyze masked mycotoxins obtained from various sources. This review shows the contribution of mycotoxin in the global food security issue as well as its deleterious effects in human and animal health.&nbsp;</span></p> <p><span style="font-weight: 400;">Int.

Among several pests, Diamondback moth (<em>Plutella xylostella.</em>L.) is a primary pest causing heavy loss of cabbage field each year in Nepal. Damage is caused by larvae. The trend of extensive and unscientific use of insecticide has resulted a devastating loss in cabbage production (31%-100%) and economic yield (US $4-US$5billion each year) on one hand and challenging the environment on the other hand. Thus integrated pest management practices, including botanical, biological, cultural methods and use of resistant varieties are effective. Annosom (extract of <em>Annona spp.</em>1%) and Neemix (extract of <em>Azadirachta indica, </em>60%w/w) are effective botanical pesticides. <em>Diadegma spp</em>, among various biological control agents, is effective. Two rows of mustard for every twenty-five rows of cabbage is effective trap cropping. Yellow sticky trap is best for DBM monitoring and control. The seasonal irrigation and rain interferes the mating and oviposition and thus control of the pest. Spinosad, Indoxacarb and Emamectin benzoate are mostly used insecticides for the control of this moth. Use of specific resistant varieties like, G 9101 and G 9619 and transgenic lines are effective but in Nepalese context, least adopted by Nepalese farmers.</p> <p>&nbsp;Int. J. Appl. Sci. Biotechnol.

As a result, there is a need for some eco-friendly bio-control agents that help in resolving the previous mentioned problems. The various types of biological control agents such as bacteria and fungi are involved in bio-control activity. Among them, fungal genus <em>Trichoderma </em>plays a major role in controlling the plant diseases. Species of <em>Trichoderma </em>are diverse fungal microbial community known and explored worldwide for their versatilities as biocontrol and growth promoting agents. These fungi reproduce asexually by production of conidia and chlamydospores and in wild habitats by ascospores. <em>Trichoderma</em> species are efficient mycoparasites and prolific producers of secondary metabolites, some of which have clinical importance. However, the ecological or biological significance of this metabolite diversity is sorely lagging behind the chemical significance. Several <em>Trichoderma </em>spp. positively affect plants by stimulating plant growth, and protecting plants from fungal and bacterial pathogens. They are used in biological plant protection as bio-fungicides as well as in bioremediation. A large number of research groups are working on various aspects of <em>Trichoderma</em> viz., diversity, ecology and their applications. The capacity of <em>Trichoderma</em> fungi to produce lytic enzymes is used in animal feed, and wine making and brewery industries. <em>Trichoderma </em>spp. are the most successful bio-control agents as more than 60% of the registered bio-fungicides used in today’s agriculture belongs to <em>Trichoderma </em>-based formulation. The increase in incidence and severity of diseases and emergence of new diseases causes the significant yield losses of different crops in Nepal. But the research and studies on plant diseases are limited.</p> <p>Int. J. Appl. Sci. Biotechnol.

Sinha <p>Copious facts have demonstrated that UV radiation is harmful to cyanobacteria. Sun-screening compounds such as mycosporine-like amino acids (MAAs) protect these organisms from deleterious UV radiation. MAAs absorb UV radiation in the range of 310 to 362 nm. These natural sunscreens obtained from cyanobacteria are excellent alternative to present day synthetic UV filters. In the present study, several cyanobacteria were collected from six historical Kunds of Varanasi, India. MAAs profile of these cyanobacteria was recorded with the help of UV-Vis spectroscopy, High performance liquid chromatography (HPLC) and Fourier transform infrared (FTIR) analysis. Various MAAs were identified as Porphyra-334 (λ<sub>max </sub>= 334 nm), Palythine (λ<sub>max </sub>= 320 nm), Asterina-330 (λ<sub>max </sub>= 330 nm), Mycosporine-glycine (λ<sub>max </sub>=310 nm) and Mycosporine-methylamine-serine (λ<sub>max </sub>=327 nm) having retention times (RT) of 3.62, 1.65, 1.53, 2.55 and 1.51 min, respectively, obtained from different cyanobacteria (<em>Microcystis aeruginosa, Anabaenopsis</em> sp., <em>Merismopedia</em> sp., <em>Aulosira fertilissima, Rivularia</em> sp., <em>Phormidium</em> sp., <em>Nostoc</em> sp. and <em>Stigonema</em> sp.). It is concluded that these MAAs from different historical Kunds may provide protection to the cyanobacteria growing thereof from the adverse effect of harmful UV radiation. MAAs are considered to be potential bioactive compounds that are highly intriguing from biotechnological perspective.</p> <p>Int. J. Appl. Sci. Biotechnol.

Nuruzzaman Md. Shohel Rana Aleya Ferdausi Md. Monjurul Huda Lutful Hassan Shamsun Nahar Begum <p>A field experiment was conducted at subtropical region in Bangladesh to assess the contribution of morphological traits to variability in some NERICA mutant rice lines. The experiment was conducted following RCBD with three replications. Thirty-one NERICA rice genotypes (twenty-eight mutant lines along with three parents) of advanced generations were used. Data were collected on twelve morphological traits. The results of the principal component analysis showed that the first four components account for 80% of total variation giving a clear idea of the structure underlying the variables analyzed. This result was also supported by scree test. Cluster analysis using Ward's method classified the thirty-one genotypes into five distinct groups. The maximum inter-cluster distance was observed between clusters indicating the possibility of high heterosis if individuals from these clusters are cross-bred. The results of PCA were closely in line with those of the cluster analysis. These results can now be used by breeders to develop drought tolerant high yielding rice varieties and new breeding protocols for rice improvement.</p> <p>Int. J. Appl. Sci. Biotechnol.

Ginger field with mulching of Khar and ginger field with mulching of forest litter was identified as two strata to collect soil sample. Thirty soil samples collected from each mulching practices. Simple random sampling procedure was followed to collect soil sample within the strata. Soil fertility parameters such as soil pH, Soil organic carbon, Nitrogen, Phosphorus, Potassium were analyzed for different mulching system. Mulching material significantly effect on Soil pH, Soil organic carbon and soil nitrogen. Soil acidity was found lower with forest litter mulch (5.53) but it was found higher for Khar mulch (5.78). Soil organic carbon was found higher in ginger field with Khar mulch (2.31%) and found lower with forest litter mulch (1.97%). Soil nitrogen level was found higher in ginger field with Khar mulch (0.20%) and found lower with forest litter mulch (0.17%). Soil available phosphorus and Potassium were not found significantly different in both type of mulching system. The result obtained from the study indicates that ginger field with Khar mulch result soil with higher soil organic carbon and Nitrogen. Mulching decision can also be made after testing the soil of respective ginger growing field. Appropriate liming could be done so that it could reduce the soil acidity problems.</p> <p>Int. J. Appl.

The experiment was conducted in Diktel Rupakot Majhuwagadhi Municipality, Khotang, Nepal to assess the soil nutrients dynamics as influenced by different cropping system. Five different cropping systems (Rice – Wheat, Maize – Millet, Maize – Vegetables, Ginger and Cardamom) were selected as treatments and all treatments were replicated for five times for blocking in Randomized Complete Block Design. Soil samples from 0-15 cm depth were collected from each site and evaluated for soil pH, soil organic carbon (SOC), total nitrogen (N), available phosphorus (P), and available potassium (K). All the tested parameters except N were found to be significantly affected by cropping system. Soil in all five cropping systems were found acidic (pH&lt;6.5) in nature with pH ranging from 5.180-6.640. The SOC was recorded highest (3.102%) from Cardamom based system and lowest amount of SOC was observed in Ginger based system. The highest amount of P (32.14 mg/kg) was reported in Maize – Vegetables cropping system and lowest P content (5.72 mg/kg) was recorded from Cardamom based system. P content in Ginger based system (31.51 mg/kg) was statistically at par with that of Rice – Wheat system. The highest K content (306.50 mg/kg) was recorded from Maize – Vegetable cropping system and lowest K content (34.80 mg/kg) was observed in Cardamom based system which is statistically similar to Rice –Wheat (35.70 mg/kg) and Maize –Millet systems (77.20 mg/kg). The result indicated that cropping systems have huge impact on plant nutrient dynamics in soil.</p> <p>Int. J. Appl. Sci. Biotechnol.

In this investigation pollen morphology of <em>Bignonia venusta</em> Ker Gawl. and <em>Jacranda mimisifolia</em> D.Don from the family Bignoniaceae; <em>Brassica compestris </em>L. from Brassicaceae; <em>Cuphea hyssopifolia </em>Kunth. from Lythraceae; <em>Coriandrum sativum </em>L. from Apiaceae; <em>Crepis japonica </em>L<strong>.</strong> and <em>Dichrocephala integrifolia </em>(L f.) kunzte. from Asteraceae; <em>Delphinium ajacis </em>L. from Ranunculaceae; <em>Dianthus barbetus </em>L. from Caryophyllaceae; <em>Euphorbia Milii</em> Des Moul. and<em> Euphorbia pulcherima </em>L. from Euphorbiaceae and <em>Magnolia fuscata</em> from Magnoliaceae were studied. Shape of the pollen grains found to be mostly spheroidal, few circular, one elliptical, one triangular and one elongated in this study. Sculpture of exine wall found to be smooth, echidnae, tected, reticulated and perforated type. Aperture of the pollen grains found to be triporate to pentaporate. The large, medium and small sized pollen grains were observed in present research. The high diversty of sculpture type in pollen grains of angiosperms has been associated to diversity in pollination systems. Smooth pollen grains are linked with wind or water pollination while sculptured pollen grains associated with biotic pollination. The morphology of pollen grain is one of the significant tools in solving some taxonomic problems such as identification, tracing phylogenetic relationship on the family, generic or specific level and in plant systematic and evolution.</p> <p>Int.

The experiment was started in November 2016 in randomized complete block design with different seven treatments of nutrients using Farm yard manure (FYM), Poultry manure (PM) Vermicompost (VC). Available N, P and K status in the soil increased gradually due to the application of inorganic and organic fertilizers. The plots receiving 50 % RDNPK through inorganic fertilizers and remaining 50% RDN through PM registered the highest available N, P and K status in the soil. The highest pH (6.3) content in soil was found in plots treatments with poultry manure and inorganic fertilizers. Potato plots treated with FYM and inorganic fertilizers produced higher SOM content in soil after harvest (2.38%) as compared to control plots (2.09%). The treatments integrated with FYM show less bulk density than the control plot. Organic manures treated plots produce taller plants as compared plots receiving inorganic fertilizers only.
