Effect of planting density and training on plant health and seed quality of bell pepper (Capsicum annuum L.) under protected conditions

A study was conducted at the Department of Seed Science and Technology, Dr. Y. S. Parmar University of Horti-culture and Forestry, Nauni, Solan (H.P.), India during Kharif 2012 to evaluate the effects of the different planting densities and training systems on plant health (powdery mildew severity) and seed quality of bell pepper cv. Solan Bharpur under pro-tected conditions (polyhouse). Experiment was laid out in naturally ventilated polyhouse using three different planting densi-ties (S1 - 45×15 cm, S2 - 45×30 cm and S3 - 45×45 cm) and four training levels (T1 - single shoot, T2 - two shoots, T3 - three shoots and T4 - four shoots)with three replicates. The combination S2T2 (plants spaced at 45x30 cm and trained to two shoots) was found superior over all other treatments in terms of seed yields i.e. per plant and per hectare (18.00 g and 959.87 kg, respectively) and was at par with important quality characters. The treatment combination S3T1 (plant spaced at 45×45 cm and trained to single shoot) resulted in least powdery mildew severity (21.21 %) and performed best for seed qual-ity characters viz. 1000 seed weight, germination percentage, seedling length, seedling dry weight, seedling vigour index-I & II (6.32 g, 95.75%, 10.86 cm, 3.26 mg, 1039.77 and 312.34, respectively) but it gave lower seed yield and thus it is uneconomic. Therefore, planting density 45×30 cm in combination with two shoot training system can be recom-mended for commercial seed production of bell pepper under protected conditions

Effect of seed treatment, soil application and foliar spray of some insecticides on seed quality of bell pepper (Capsicum annuum L.)

Studies were carried out to evaluate the efficacy of some insecticides as seed treatment, soil application and foliar sprays on seed quality characters of bell pepper (Capsicum annuumL.) cultivar Solan Bharpur during Kha-rif season 2013. The treatments comprised of seed application of imidacloprid (Gaucho 600FS) and thiamethox-am (Cruiser 70WS), soil application of neem cake@ 2 q/acre and carbofuran @ 6 kg/acre and foliar sprays of im-idacloprid (Confidor 200 SL), thiamethoxam (Actara 25 WS), indoxacarb14.5 SC @ 0.5ml/l, NSKE (neem seed ker-nel extract) @ 5%, Neem Raj 500ppm @ 2.5ml/l and control. The observations regarding quality parameters record-ed were germination percentage, seedling length, seeding dry weight, seed vigour index-I, seed vigour index-II and electrical conductivity. The results revealed that treatment combination viz., seed treatment and foliar spray with thiamethoxam (S2F2) recorded significantly higher germination percentage (96.33%), seed vigour index-I (934.10), seed vigour index-II (245.02) and minimum electrical conductivity (216.67dSm-1) at 0.05 level of significance. Therefore, seed treatment and foliar spray of thiamethoxam may be recommended for quality seed production of bell pepper

Hypophosphatemic effect of niacin extended release in ischemic kidney disease

Ischemic nephropathy is an emerging cause of end stage renal disease, associated with many co-morbidities especially cardiovascular disease risk and derangement in calcium-phosphorus homeostasis resulting in hyperphosphatemia, influencing bones, a characteristic of advancing chronic kidney disease. The management of elevated serum phosphorus has been a challenge in this patient population with compromised kidney performance, as available phosphorus lowering agents possess many undesirable hazardous secondary effects and/or are very expensive. While niacin in different formulation is known to not only correct dyslipidemia but also reduce phosphorus level, but its clinical use restricted owing to side effects. The objective of present study is to evaluate such effect of niacin extended release (NER) in ischemic nephropathy. The chronic kidney disease patients fulfilling the pre-defined criteria were randomly categorized into two groups of equal size (n=60) and prescribed either atorvastatin 20 mg/day or NER 500 mg/day with the same dose of statin for four months. A control of 50 healthy characters matched was also incorporated for local reference range. Baseline and follow up phosphorus concentration was measured and means were compared using t-test at SPSS version 17 with 0.05 chosen alpha. There was no difference in the baseline levels in both groups while significant (p<0.001) hyperphosphatemia was observed in both units as compared with healthy controls. The administration of atorvastatin alone for four weeks showed an insignificant decrease in phosphorus, whereas, NER significantly reduced phosphorus (p<0.001). The mean percent change from baseline to follow up further endorsed the finding as statin alone brought -13.8 % reduction in phosphorus and NER -47 % from baseline. NER, at its lowest prescribed dose once a day was well tolerated by most of the patients and demonstrated significant goal achievement of phosphorus reduction. It is concluded that NER even at low doses in renal compromised dyslipidemic patients may be a promising approach to prevent the harmful vascular, valvular effects caused by hyperphosphatemia in addition to its principal target of HDL-C elevation

Dissociation of J/ψ\psi and Υ\Upsilon using dissociation energy criteria in N-dimensional space

The analytical exact iteration method (AEIM) have been used widely to calculate N-dimensional radial Schrodinger equation with medium modified form of Cornell potential and is generalized to the finite value of magnetic field (eB) with quasi-particle approach in hot quantum chromodynamics (QCD) medium. In N-dimensional space the energy eigen values have been calculated for any states (n,l). These results have been used to study the properties of quarkonium states (i.e, the binding energy and mass spectra, dissociation temperature and thermodynamical properties in the N-dimensional space). We have determined the binding energy of the ground states of quarkonium with magnetic field and dimensionality number. We have also determined the effects of magnetic field and dimensionality number on mass spectra for ground states of quarkonia. But main result is quite noticeable for the values of dissociation temperature in terms of magnetic field and dimensionality number for ground states of quarkonia after using the criteria of dissociation energy. At last, we have also calculated the thermodynamical properties of QGP (i.e., pressure, energy density and speed of sound) using the parameter eB with ideal equation of states (EoS).Comment: 14 pages, 11 figure

Study of Differential Scattering Cross-section using Yukawa term of medium-modified Cornell potential

In the present work we have studied the Differential Scattering Cross-section for ground states of charmonium and bottomonium in the frame work of the medium modified form of quark-antiquark potential and Born-approximation using the non-relativistic quantum chromo-dynamics approach. To reach this end, quasi-particle (QP) Debye mass depending upon baryonic chemical potential ($\mu$b) and temperature has been employed and hence the variation of Differential Scattering Cross-section with baryonic chemical potential and temperature at fixed value of the scattering angle ($\theta=90^\circ$) has been studied. The variation of Differential Scattering Cross-section with scattering angle $\theta$ (in degree) at fixed temperature and baryonic chemical potential has also been studied. We have also studied the effect of impact parameter and transverse momentum on differential scattering cross-section at $\theta=90^\circ$.Comment: 13 pages, 8 figures (Accepted in advances in High Energy Physics Journal
