Effect of different levels of customized fertilizer on soil nutrient availability, yield and economics of onion
A field experiment was conducted to study the effect of different levels of customized fertilizer (CF) on soil nutrient availability, yield and economics of onion. The results revealed that the significantly highest plant height (57.77cm), stem diameter (6.03cm) and bulb diameter (15.13cm) at the time of harvest, fertilizer use efficiency,bulb yield (22.34 t ha-1) and benefit:cost ratio (2.56) of onion were recorded in 100 % recommended dose of NPK through CF in three equal split doses. The significantly highest available nitrogen (213 kg ha-1), phosphorus (14.42 kg ha-1) were recorded in 125 % recommended dose of NPK through CF in two equal split doses and available K (804 kg ha-1) in 100 % recommended dose of NPK through CF in three equal split doses over the rest of the other treatments. The application of 100% recommended dose of fertilizer (100:50:50 N:P2O5:K20 kg ha-1) either two or three splits through CF to onion appears to be improving soil fertility, yield and yield contributing character of onion and getting higher net monetary returns

Impact of different levels of organic and inorganic fertilizers on growth, yield and quality of preseasonal sugarcane ratoon in Inceptisols
A field experiment was conducted at soil test crop response (STCR) correlation project farm of Mahatma Phule Krishi Vidyapeeth, Rahuri Maharashtra.The result showed that individual application of nitrogen (N), phosphorus(P),potassium(K) or organic nutrient sources (Farm yard manure) recorded less value of preseasonal sugarcane ratoon but the integration of both the sources showed significantly improved all the growth, yield and quality parameters of preseasonal sugarcane ratoon. The maximum number of internodes were ranged between 21-30 with mean of 25.42, number of leaves 6-10 with mean of 7.21, length of internodes 12.50-16.80 cm with mean of 14.41 cm, girth of internodes 11.30-13.10 cm with mean of 12.15 cm and height of millable cane 335-385 with mean of 351.75 cm, respectively were found higher with application of residual effect of 30 t ha-1 farm yard manure (FYM). However, the quality traits viz., brix ranged from 18.70 to 22.80 with mean of 19.87, pol per cent ranged from 15.81 to 18.41 per cent with mean of 17.53 per cent and commercial cane sugar (CCS) per cent from 9.39 to 12.09 per cent with mean of 10.76 per cent. The CCS yield was ranged between 9.58-16.30 MT ha-1 with mean value of 14.13 MT ha-1were enhanced considerably with residual 15 and 30 t FYM ha-1 blocks over without FYM. The application of organic and inorganic fertilizers will not only enhance the growth, yield and quality of preseasonal sugarcane ratoon but also conserve agro-ecosystem for sustainable crop production
Soil test crop response based Integrated plant nutrition system for desired yield target of preseasonal sugarcane ratoon on Inceptisols
Studies on Soil Test Crop Response based Integrated Plant Nutrition System (STCR - IPNS) were conducted adopting the Inductive cum Targeted yield model onInceptisols (VerticHaplustepts) in Rahuri, District Ahemadnagar, Maharashtra, India in order to develop fertilizer prescriptions through IPNS for the desired yield targets of preseasonal sugarcane ratoon. The field experiments were carried out with maize as gradient crop for plant cane and after harvest of plant cane, pre-seasonal sugarcane ratoon as test crop. Using the data on yield, initial soil test values on available nitrogen (N), phosphorus (P), potassium (K), doses of fertilizers and farmyard manure (FYM) applied and NPK uptake, the basic parameters viz., nutrient requirement, contribution from soil, fertilizers and FYM were computed. It was found that 1.56 kg N, 0.58 kg P and 1.04 kg K were required for producing one tonnemillable cane of preseasonal ratoon sugarcane. The per cent contributions of N, P and K from soil and FYM for preseasonal sugarcane ratoon were 37.65, 85.88 and 19.82 per cent and 11.83, 10.88 and 12.24 per cent, respectively. Making use of these basic parameters, fertilizer prescription equations were developed for pre-seasonal sugarcane ratoon (var. C0-94012) and an estimate of fertilizer doses formulated for a range of soil test values and desired yield targets under NPK alone and IPNS (NPK plus FYM)

Use Pattern and Information Needs of Young Users of Public Libraries in Karnataka with Special Reference to City Central Library (CCL), Dharwad
In this article an attempt has been made to investigate the use pattern and information needs of young users. For the study 200 questionnaires were distributed to the young users of City Central library, Dharwad, aged between 18-35 years and 196 duly filled questionnaires were received back with the response rate of 98%. In that, 180 (90%) questionnaires were found to be suitable for the analysis. Findings of the study revealed that City Central library plays a vital role in the life of youngsters and they are visiting the library regularly. Library usage and information needs of youngsters are mainly related to employment (81.11%) and education (66.57%). The study concludes with providing some of the important suggestions for overall development of information resources, services and infrastructure facilities of the CCL in order to provide better services to young users

A giant cobia, Rachycentron canadum was landed at Sassoon duck, Mumbai on 18-08-2003 by a gill-netter operated at a distance of 25-30 km south west of Mumbai at the depth of 20-25m.The species is distributed world wide in warm seas except for the eastern pacific regoin. It is pelagic but also found over shallow coral reefs and off rock shores,occasionally enters in estuaries
A concise enantioselective synthesis of (R)-(+)-goniothalamin oxide, a trypanocidal active agent via L-prolinol catalyzed asymmetric epoxidation of cinnamaldehyde
393-398A short and straight-forward enantioselective synthesis of (R)-(+)-goniothalamin oxide 2 has been achieved with an overall yield of 39% and 99% ee. The synthetic approach involves l-prolinol catalyzed asymmetric epoxidation of cinnamaldehyde followed by Lewis acid-mediated diastereoselective allylation of epoxy aldehyde as the key chiral-inducing steps
Relativistic supernovae have shorter-lived central engines or more extended progenitors: the case of SN\,2012ap
Deep late-time X-ray observations of the relativistic, engine-driven, type Ic
SN2012ap allow us to probe the nearby environment of the explosion and reveal
the unique properties of relativistic SNe. We find that on a local scale of
~0.01 pc the environment was shaped directly by the evolution of the progenitor
star with a pre-explosion mass-loss rate <5x10^-6 Msun yr-1 in line with GRBs
and the other relativistic SN2009bb. Like sub-energetic GRBs, SN2012ap is
characterized by a bright radio emission and evidence for mildly relativistic
ejecta. However, its late time (t~20 days) X-ray emission is ~100 times fainter
than the faintest sub-energetic GRB at the same epoch, with no evidence for
late-time central engine activity. These results support theoretical proposals
that link relativistic SNe like 2009bb and 2012ap with the weakest observed
engine-driven explosions, where the jet barely fails to breakout. Furthermore,
our observations demonstrate that the difference between relativistic SNe and
sub-energetic GRBs is intrinsic and not due to line-of-sight effects. This
phenomenology can either be due to an intrinsically shorter-lived engine or to
a more extended progenitor in relativistic SNe.Comment: Version accepted to ApJ. Significantly broadened discussio
