Abstract:
The present investigation was carried out to study the effect of integrated weed management on the seed growth parameters of cucumber. The study was conducted at the Department of Vegetable Science, Horticultural College and Research Institute, Coimbatore during 2019-2020. The experiment was laid out in Randomized Block Design. Different combinations of pre and post emergence herbicides were used to control the weed population. A total of eleven treatments were used and were replicated three times. Observations on seed growth parameters viz., germination percentage, speed of germination, seed vigour index I and seed vigour index II were recorded. Among the different treatments, Post emergence application of Quizalofop @ 40g/ha @25DAS with one hand weeding 45 DAS showed better seed growth parameters. The results showed that the treatment T₄ (Post emergence application of Quizalofop @ 40g/ha @25DAS) recorded the highest germination percentage (87), speed of germination (11.1), seed vigour index I (2294.5) and seed vigour index II (1.31).The lowest seed growth parameters were recorded in T₁₁ (weedy check). Hence, it can be concluded that post emergence application of Quizalofop @ 40g/ha @25DAS can be beneficial in controlling the weed population in cucumber.
