A field experiment was conducted during Kharif 2012 and 2013 at AEEC, Lingsugur, UAS, Raichur. Nine treatments were laid out in randomised design with three replications. Among different sources of nutrients, foliar spray of Panchagavya (5 %) at flower initiation recorded significantly higher grain yield of greengram compared to other treatments however, it was at par with foliar of spray of 19:19:19 (1%) in both year and as well in pooled analysis. The significantly lower grain yield was recorded in control plot in both the years.

The varied dosages of Chlorantraniliprole 35%WG in comparison with different insecticides were tested along with untreated check using randomized block design with three replications. Significant differences were noticed among the treatments. Among the different insecticides evaluated. Drenching the sets immediately after planting in furrow with Chloranthriniliprole 35%WG @ 88 gai/ha and Chloranthriniliprole 35%WG @ 75 gai/ha, were proved superior by recording lowest average per cent dead hearts by early shoot borer and average per cent Internode borer damage whereas untreated control recorded highest pest infestation and also recorded the B:C ratio of 3.26, 3.18 and 2.16 respectively.

Semen characteristics of 97,112 ejaculates from 399 adult bulls of 2 exotic breeds, 2 indigenous breeds and crossbred sub-populations with 50% and 75% of exotic inheritance, and of 3,293 ejaculates from 292 test bulls were analysed. The traits considered were: ejaculate volume, sperm concentration, total number of sperms, initial and post-thaw motility, and a theoretical number of doses produced from each given ejaculate. The objective was to measure the semen production potential of different genetic groups of cattle breeds, to identify factors affecting semen production and quality traits, and to assess the correlation between semen characteristics measure on test and adult bulls. A linear mixed model was used to evaluate the effect of different fixed and random effects. For adult bulls, the first ejaculate of a bull on a particular day and longer collection intervals lead to better characteristics for all the parameters but short collection interval with two ejaculate on particular day lead to a larger number of total semen doses produced without hampering semen quality. Repeatability estimates for semen traits were found to be low to moderate. Low to moderate and negative bull correlation was observed between concentration and volume in all the breed groups while the correlations of bull effects of the two motility traits were comparatively large. The moderate to high correlation for all semen traits between their testing and when they are adult highlights the importance of andrology evaluation in predicting future semen production of AI bulls in order to discard the less productive bulls.
