    Abstract Curative medicine and curative surgery are no doubt of interest to every body. However, a host of diseases in the area of ear, nose & throat are curable, on the other hand, a number of them are only controllable, not curable. Several amongst them are preventable as such or their complications and sequelae can be prevented or minimised. It is high time that more awareness is created towards better understanding of the preventive aspect of Otorhinolaryngology practice. The time & energy spent on managing complications & sequelae can be easily saved and easily utilized in a better way in improving expertise to cure the diseases through more research & interaction.

    Abstract A field experiment was conducted during the rainy (kharif) season of 2015 at Varanasi, Uttar Pradesh, to assess the effect of phenophase-based nitrogen and zinc scheduling on yield, and zinc content of direct-seeded rice (Oryza sativa L.). The experiment was laid out in a factorial randomized block design with 3 replications, having 3 nitrogen levels (N₀, 0 kg N/ha; N₁, 120 kg N/ha (50% at sowing + 25% at G + 25% at G₂₁); N₂, 160 kg N/ha (50% at sowing + 25% at G₂₁+ 25% at G₃₂) and 5 zinc scheduling (Zn₀, 0 kg Zn/ha; Zn, 5₁ kg Zn/ha basal + 0.3% ZnSO₄. H₂O spray at G₄₅ and G₆₁; Zn, 10 kg Zn/ha basal + 0.3% ZnSO₄. H₂O spray at G₄₅ and G 61; Zn₃,5 kg Zn/ha basal + 0.3% ZnSO₄. 2H₂O spray at G ₅₁+ G₇₃; Zn, 10 kg Zn/ha at basal + 0.3% ZnSO₄. 2H₂O spray at G₅₁ + G₇₃). Significantly highest effective tillers, panicle length, grains/panicle, panicle weight, 1,000–grain weight, grain and biological yields were recorded with independent application of N₂ and Zn₂ over the others, however the highest zinc content and uptake in grain recorded with N₂ and Zn₄ treatments. Nitrogen levels and Zn scheduling also positively interacted and recorded the highest grain yield with N₂ × Zn₂, however the highest grain N and Zn content were recorded with N₂ × Zn₄.

    Abstract An experiment was conducted during the rainy season of 2015 at South Campus, Banaras Hindu University, Mirzapur, Uttar Pradesh, to study the effect of 3 agri-horticultural systems, viz. guava (Psidium guajava L.), custard apple (Annona squamosa L.) and open field, and 4 weed-management practices (pendimethalin 750g a.i/ha + hand-weeding (30 DAS); imazethapyr 75g a.i/ha (PoE) + intercultivation (IC) (45 DAS); quizalafop ethyl 40 g a.i/ha (PoE) + IC (45 DAS); and weedy check) on sesame (Sesamum indicum L.). Guava agri-horti system recorded higher plant height, biomass, capsule count and seed yield and also recorded less infestation of total weeds; whereas open field recorded the highest weed infestation. Pendimethalin recorded the highest weed-control efficiency (94.9% on density basis and 92.6% on biomass basis) at 40 DAS but reverse results observed after intercultivation as quizalofop-ethyl recorded significantly the lowest infestation of weed and recorded the highest plant biomass, capsule content, test weight and seed yield of sesame. In our study, guava proved a compatible agri-horti system for introduction of sesame and quizalofop ethyl 40 g a.i/ha (PoE) + IC (45 DAS) treatment as best for management of weeds and enhancing productivity.

    Abstract A key requirement in the field of ultrafast vibrational spectroscopy is to efficiently generate intense tunable narrowband picosecond laser pulses synchronized to a broadband femtosecond laser source. Current nonlinear methods for picosecond pulse generation suffer from complexities in both experimental implementation and pulse frequency tunability. We present here a straightforward method for spectral bandwidth compression that produces frequency tunable picosecond pulses with efficient power conversion. Broadband femtosecond laser pulses are compressed to narrowband picosecond pulses using frequency domain sum-frequency generation of spatially chirped pulses, achieving spectral bandwidths of <20 cm

    Abstract A field experiment was conducted during the rainy (kharif) season of 2014 at Varanasi, Uttar Pradesh, to study the effect of nitrogen levels and zinc application on yield and zinc content of direct-seeded (Oryza sativa L.) rice (DSR). Among the different nitrogen levels, the application of 150 kg N/ha recorded the highest yield attributes, viz. effective tillers at harvesting (77 running/m), panicle length (24.75 cm), grains/panicle (205), test weight (22.47 g) and panicle weight (2.4 g), which resulted in the highest grain (4.34 t/ha) and biological yield (10.08 t/ha). Among different zinc schedules; the application of 0.3% ZnSO₄.H₂O spray at anthesis recorded the highest yield attributes, viz. effective tillers at harvesting (72 running/m), panicle length (24.11 cm), grains/panicle (202), test weight (21.48 g) and panicle weight (2.73 g), resulting in highest grain (4.36 t/ha) and biological yield (10.27 t/ha). Harvest index was also influenced by nitrogen levels but not by zinc scheduling, although it was found nonsignificant. However, the highest net returns (41.27 × 10³/ha) and benefit: cost ratio (1.04) were recorded with the application of 150 kg N/ha, while in case of zinc scheduling the maximum net returns (43.27 × 10³/ha) and benefit: cost ratio (1.10) were reported with the application of 0.3% ZnSO₄.H₂O spray at anthesis. Combine application of 150 kg N/ha and 0.3% ZnSO₄.H₂O spray at anthesis was found optimum for grain yield (5.58 t/ha) of direct-seeded rice.

    Abstract A field experiment was conducted during the rainy (kharif) season of 2011–12 at Mirzapur, Uttar Pradesh to study the response of pearlmillet [Pennisetum glaucum (L.) R. Br.] to nitrogen and zinc on Zn biofortification in this crop. The field experiment was laid out in a factorial randomized block design, with 3 replications, comprising 4 nitrogen (N) levels (0, 20, 40 and 60 kg N/ha) and 3 levels of zinc (0, 5 and 10 kg Zn/ha) with constant rates of phosphorus and potassium at 40 and 30 kg/ha respectively. Application of 60 kg N/ha and 10 kg Zn/ha resulted in the maximum grain yield, N content and uptake by grain and stover of pearlmillet. Zinc content in grain linearly enhanced with sole application of N and Zn levels up to 20 kg N/ha and 5 kg Zn/ha. Combined application of 5 kg Zn/ha × 20 kg N/ha was found optimum for enhancement of Zn content in grains of pearlmillet. Agronomic nitrogen and zinc efficiency decreased with the increasing nitrogen and zinc levels.

    Abstract The efficacy of thiamethoxam as seed treatment and oxydemeton methyl as a foliar spray on soybean was evaluated against YMV transmitted by whitefly, Bemisia tabaci in different cvs. of soybean during kharif season in relation to weather variables. The peak population of whiteflies reached 5ᵗʰ week after sowing in seven varieties in treated plots. The whiteflies population reduced significantly in all the treated plots up to the maturity stage of the crop. The weather variables except sunshine hours had a positive correlation with whitefly population. The cvs., PK-416 and PK-1042 identified as resistant against YMV with a rating scale of 2–2.33 in untreated plots and about 1.66 in treated plots. The treated cv., Bragg yielded the least of 13.00q/ha whereas, PS-16 yielded maximum of 24.00q/ha.
