Influence of Different Weed Control Practices on Growth and Growth Analysis Parameters of Kharif French Bean (phaseolus Vulgaris L.)

A field experiment was carried out at experimental farm of Agronomy section, College of Agriculture, Latur during Kharif 2018 to study the effect of applications of pre emergence and post emergence herbicides on functional leaves, leaf area and growth analysis parameters of kharif French bean (Phaseolus vulgaris L.). The experiment was laid out in a Randomized Block Design with seven treatments and replicated thrice. The significantly maximum no. of functional leaves were observed at 60 DAS with weed free treatment (T6). But which was found at par with application of Pendimethalin 30% EC @ 1.0 kg a.i. ha-1 (PE) + one hoeing at 30 DAS (T3) and application of Quizalofop-p-ethyl 5% EC @ 100 g a.i. ha-1 at 20DAS (POE)+ one hoeing at 30 DAS (T4). Maximum leaf area plant-1 were recorded with the weed free treatment (T6) which was found at par with Quizalofop-p-ethyl 5% EC @ 100 g a.i. ha-1 at 20 DAS + one hoeing at 30DAS (T4). Mean values indicating that weed free treatment (T6) recorded higher values in case of AGR for plant height and AGR for dry matter upto 45 DAS as compared to all other treatments. Maximum value for Leaf area Index recorded with weed free treatment (T6) which was followed by application of Pendimethalin 30% EC @1.0 kg a.i.ha-1(PE) + One hoeing at 30 DAS (T3) and Quizalofop-p-ethyl 5% EC @ 100 g a.i. ha-1 at 20 DAS + one hoeing at 30DAS (T4) upto 45 DAS as compared to other treatments.
