    Response of pearl millet (Pennisetum glaucum L.) to vermicompost, biofertilizers and nitrogen levels
    (CCSHAU, 2017) Manjeet; Parveen Kumar
    The present study entitled “Response of pearl millet (Pennisetum glaucum L.) to vermicompost, biofertilizers and nitrogen levels.” was conducted at Agronomy Research Area, CCSHAU,HISAR during Kharif 2016 with the objective to study the effect of vermicompost, biofertilizers and nitrogen level on growth, yield attributes and yield, nutrient uptake and economics of pearl millet hybrid HHB-223. In the main plot there were manurial treatment viz. control, biomix, vermicompost @ 2.5 t ha-1 and vermicompost @ 2.5 t ha-1 + biomix. In sub plot there was nitrogen levels viz. 70, 80, 90 and 100 per cent RDN so there were a total 16 treatment combination. Different nutrient management practices did not differ significantly in respect of various phenological events viz. emergence, five leaf stage and initiation of the milking while boot stage, 50 per cent flowering and physiological maturity were affected significantly and more days were taken with biomix + vermicompost @ 2.5t ha-1 under different manurial treatments. The growth parameters viz. [plant height (cm), LAI, total number of tillers plant-1, dry matter accumulation (g plant-1) and leaf area plant-1 (cm2)], yield attributing characters [effective tiller plant-1, earhead length (cm), earhead girth (cm), test weight (g)] and grain, stover yield (Mg ha-1) differed significantly among different treatments. Among manurial treatment these character were higher with biomix + vermicompost @ 2.5t ha-1 and with 100 per cent RDN with different nitrogen level. Higher N content and uptake was with biomix + vermicompost @ 2.5 t ha-1 in manurial treatment and 100 per cent RDN with different nitrogen levels. Also, availability of nutrient (N, P and K) after harvest in soil increased with increasing level of nitrogen and was highest in biomox + vermicompost @ 2.5 t ha-1 treatment among manurial treatment. In manurial treatment higher gross return (` 50252) and net returns (` 17532) were recorded with biomix + vermicompost @ 2.5 t ha-1. Gross return, net returns and B:C ratio of pearl millet increased with increasing level of nitrogen and their highest value were recorded with 100 per cent RDN and was ` 48217, ` 21036 and 1.77, respectively but almost comparable with 90 per cent RDN. Hence, for enhancing crop growth characters, yield attributes, yield and monetary returns pearl millet seed should be treated with biomix and fertilized with 90% RDN along with vermicompost application @ 2.5 t ha-1.
