An investigation was undertaken to evaluate the impact of different crop residues on late
jute seed yield and organic matter content of soil. The plant height, number of branch/plant,
number of pod/plant, number of seeds/pod and seed yield/plant were significantly increased
with different crop residues. The performance in seed yield were dry jute leaves (89.30%)
> lentil straw (87.77%) wheat straw (43.28%) > compost (35.35%) > rice straw
(32.740%) > saw-dust (16.91%) over the control. The resources increased the soil organic
matter content in soil by 24.59, 22.92, 26.22, 19.67, 29.51 and 30.33% respectively over
the control indicating the enrichment of soil health. In correlation studies it was observed
that the jute seed yield parameters, the seed yield was highly correlated with plant height,
number of branches/plant and number of pods/plant. |

Six fungicides viz., cupravit, thiovit, dithane M-45, bavistin, rovral and suncozeb
were tested against C. gloeosporioides. Dithane M-45, rovral,
thiovit and suncozeb were the most effective ones. Cupravit and bavistin
were less effective in the inhibition of conidial germination. Ten plant-extracts
considered as fungicides were tested, out of which Tagetes erecta leaf
and Azadirachta indica bark extracts were the most effective in inhibiting
Colletotrichum gloeosporioides after 5-30 minutes of immersion and in
5:1.25 (w/v) concentration. The phytohormone IAA had great effect against the
inhibition (100%) of C. gloeosporioides at 0.005 to 0.006% concentration
for an immersion after 5-30 minutes. Rest of the hormones also had good effects
against C. gloeosporioides. |
