Journal Title: IMPACT : International Journal of Research in Applied, Natural and Social Sciences ( IMPACT : IJRANSS ) - Year 2017, Vol 5, Issue 11
Abstract
A field experiment was conducted at Udaipur (Rajasthan), to find out the effective weed and nutrient management practice, in coriander. Amongst eight weed species identified, only Chenopodium murale L, Spergula arvensis L. and Melilotus indica was found, the most dominate. Two HW at 30 and 45 days after sowing and pendimethalin 1.0 kg/ha + HW at 45 DAS were found superior over rest of the treatments with respect to control of density of all weeds and coriander seed yield. For the control of Spergula arvensis population, Two HW at 30 and 45 days after sowing stands the best practice of weed management, in coriander. Application of metribuzin 0.30 kg/ ha at pre-emergence was found least effective, in the control of various weeds and improving coriander seed yield, compared to other treatments under test. Nutrient management involving N+P+K+S application, though enhanced density of all weeds, as compared to N+P and N+P+K application, but the difference was found statistically non significant. The balanced fertilization, significantly increased the seed yield of coriander with the maximum peak at 60 kg N+ 30 kg P + 30 kg K + 30kg S/ha.
