Journal Title: International Journal of Agriculture Sciences - Year 2017, Vol 9, Issue 14
Abstract
A field experiment was conducted during Rabi season of 2012-13 and 2013-14 at Horticulture Farm, RCA, Udaipur, involving the assessment of quantitative losses due to insect pests of cabbage. The cabbage variety Golden Acre was sown in 26 plots with each plot measuring 3.6 x 3.6 m2. One set of plots was kept protected from insect infestation by regular application of recommended pesticides and the other set was exposed to natural infestation throughout the crop growth. The insect-pests infestation caused 21.76 and 20.15 per cent reduction in plant height of cabbage during rabi 2012-13 and 2013-14, respectively. The insect-pests infestation also affected the weight of cabbage head per plant with a mean loss of 25.17 and 23.73 per cent during rabi 2012-13 and 2013-14, respectively. On the basis of difference obtained in net yield between protected and unprotected plots, the avoidable quantitative loss was estimated as 32.67 per cent during 2012 and 29.33 per cent during 2013.
