Management of white fly, Bemisia tabaci (Gennadius) through seed treatment in moth bean

A seed treatment trial was conducted at research farm of Centre of Excellence for Research on Pulses, S. D. Agricultural University, Sardarkrushinagar. The experiment was conducted for the control of white fly by seed treatment, four insecticides were used for seed treatment with two different doses of each insecticides viz., Bifenthrin 10 EC, Imidacloprid 600FS,Thiomethoxam 35 FS and Fipronil 5%SC, these treatments were found significantly (at 5 %) superior over the control in reducing the white fly population in moth bean. The seed treatment with Thiomethoxam35 FS @5g/kg seeds found minimum white fly, Bemisia tabaci population (0.32 /leaf) followed by Imidacloprid 600FS @ 5 g/kg seeds (white fly 0.39/leaf) and maximum was recorded in control ( 1.06/leaf. Farmers are advised to use seed treatments with Thiomethoxam35 FS @5g/kg seeds or Imidacloprid 600FS @ 5 g/kg seeds before the sowing of moth bean crop for the control of white fly

Genetic variability and character association in fenugreek (Trigonella foenum-graecum L.)

Sixty four genotypes of fenugreek (Trigonella foenum-graecum) were evaluated for geneticvariability, correlation and path coefficient analysis at Jagudan (Gujarat). Phenotypic andgenotypic coefficients of variability were high for grain yield plant-1, number of pods plant-1and number of primary branches plant-1. Moderate heritability estimates along with highgenetic advance as percentage of mean were recorded for number of pods plant-1. Highheritability estimates along with moderate to low genetic advance as percentage of meanwere recorded for days to maturity and plant height. Grain yield was positively correlatedwith number of pods plant-1, number of seeds pod-1 and 1000 seed weight. Results of pathanalysis revealed that number of pods plant-1, days to 50% flowering and test weight hadhighest positive direct effects on grain yield. It was concluded that improvement of seed yieldin fenugreek is possible through selection for number of pods and seed weight throughnumber of grains and length of pods. &nbsp

Study the influence of climate change on Clavigralla gibbosa (Spinola) in pigeonpea

Monitoring and population dynamics of tur pod bug, Clavigralla gibbosa in unprotected pigeonpea crop during kharif seasons from 2011 to 2014 at the Farmers field of Jurdcial area of S.D. Agricultural University, S.K. Nagar, North Gujarat, India. Temperature, rainfall and host-plant species were analyzed with respect to population fluctuation of the tur pod bug. The observations revealed that, the average number of larval population per plant in the season (from 27th to 3rd standard weeks) was 0.97, 0.32, 0.30 and 0.38 larvae per plant during 2011, 2012, 2013 and 2014 respectively. Population of C. gibbosa had significant and negative correlation with maximum temperature (r= -0.73), rainfall (r= -0.29) and relative humidity (r= -0.79, r= -0.58 morning and evening, respectively)

Though, it does not contain petroleum but can be blended with petroleum and diesel or can be used in its pure from. The use of bio-diesel in conventional diesel engines has significance to have pollution free environment since it helps to in substantial reduction of unburnt hydrocarbons, carbon monoxide and particulate matters.Not Availabl

Not AvailableAn experiment was conducted at Indian Institute of Rice Research, Hyderabad, toassess the response of 34 hybrid rice parental lines to 120mM Nacl salt stress at germination stage. All the genotypes significantly responded to salt stress and most of the genotypes showed tolerance to threshold salt level and the results clearly depicted that germination stage is moderately tolerant to salinity. Root and shoot length of all cultivars were significantly affected by salt stress, The genotypes BK49-76, BK36-167, INDAM300-007, AjayaR, FL-478 and DRRH-2 manifested maximum tolerance where as genotypes BCW 56, IR 58025B, APMS6B showed susceptibility on par with IR28 at germination stage. The most of the genotypes were tolerant to salinity at seed germination which is an indicator for raising nursery in salt affected soils.Not Availabl
