EFFECT OF ORGANIC AMENDMENTS AND CARBENDAZIM ON NODULATION AND CONTROLLING OF FOOT AND ROOT ROT OF LENTIL

Abstract

The present study was conducted for the effect of organic amendments and Carbendazim on nodulation and controlling of foot and root rot of lentil in in- vitro and in-vivo conditions at Sher-e-Bangla Agricultural University, Dhaka, Bangladesh during the period from November 2018 to May 2019. The experiment consists of 8 treatments such as T 0 = Control, T 1 = Poultry manure, T 2 = Cow dung, T 3 =

Spent mushroom compost, T 4 =

Carbendazim 50WP, T 5 = Spent mushroom compost + poultry manure, T 6 =

Spent mushroom compost + cow dung, T 7 = Spent mushroom compost + Carbendazim 50WP. BARI masur 4 variety was used in this experiment. In in-vitro condition, the reduction of mycelium growth was varied from 12.22% to 36.48% and the highest reduction was recorded in T 7 . In field experiment, the lowest disease incidence (10.57%) was recorded in T 7 and the highest disease incidence in control (47.30%). The highest percent reduction of disease incidence over control was found in T 7 (77.65%)

followed by T 6 (75.58%). In all cases of yield contributing characters such as number of nodules/plant, pods/plant, seeds/pod, 1000-seed weight and grain yield increased by the combination of spent mushroom compost with cow dung. Significantly the highest yield (1486.70 kg/ha) was found under the treatment T 6 followed by T 7 (1425.70 kg/ha) and T 5 (1403.80 kg/ha), respectively. Carbendazim alone and in combination of spent mushroom compost with Carbendazim and cow dung were statistically similar in respect of performance against Foot and root rot of lentil.
