Broccoli is an important cole crop, grown widely
in the North Eastern states of India. The deficiency of soil
moisture in mid-hills is one of the most limiting factors
affecting the production and productivity of the crops. To
evaluate the effect of different mulching materials on soil
environment, productivity and quality aspect of broccoli
(Hybrid Puspa), the experiment was conducted for three
years during 2013–2016. Among the treatments, highest
photosynthetic rate (34.81 mmol m-2 s-1), transpiration
rate (7.86 mmol m-2 s-1), stomatal conductance
(180.08 mmol m-2s-1), low intercellular CO2 concentration
(50.06 ppm), highest chlorophyll a (0.25 g kg-1), b
(0.06 g kg-1) and a/b ratio (4.31) as well as anthocyanin
content (0.62 mg g-1) was recorded from the treatment T3
(Dry weed biomass mulch of Eupatorium and Ambrosia
spp. @1 kg m-2 area). Similarly, treatment T3 was also
found to be superior for the number of leaves, leaf length,
leaf weight, stalk length and weight, head length and
diameter. The highest marketable head yield (22.75 t ha-1)
was in T3 mulch and it was 57% higher over the control.
Poly mulch has shown the higher soil moisture and temperature
throughout growing period. The highest available
nutrients such as soil organic carbon and NPK content were
observed in poly mulch. For quality traits such as dry
matter, total sugar, b-carotene and vitamin-C content, the
control was superior. It was observed that, mulching has
positive effect on the yield as well as quality and available
biomass in this region can be a better alternative for the
resource poor farmers of this region.
