Vellanikkara during 2000-2001 to study the influence of organics and biofertilizers on
yield and quality of black pepper varieties Panniyur 1 and Panniyur 2. The salient
findings are abstracted below:
Vegetative characters except number of leaves per lateral did not show
significant effect of applied organics and biofertilizers. Fresh and dry yields of berries
per vine as well as drying percentage of berries also failed to produce any significant
difference among treatments.
With respect to quality attributes like essential oil, oleoresin and piperine
contents, an integrated nutrient management with biofertilizer + organic + inorganic
combination was found significantly superior.
In general, treatments involving complete orgaruc and biofertilizer +
organic + inorganic combinations exhibited higher values of all soil nutrients except S,
Ca and Zn.
Foliar N, P and K contents recorded higher values with FYM + inorganic
treatments while Ca and S uptake were better with biofertilizer treatments. Uptake of
Mg and micronutrients exhibited no significant treatment differences.
Biofertilizer applied plots registered higher soil microbial population of
fungi, bacteria and actinornycetes.
Significant positive correlations with yield were exhibited by plant height,
canopy spread, number of laterals, number of spikes, spike length and number of
berries per spike in both the varieties.
Higher benefit cost ratio was recorded by control plots in both the varieties.
Excluding control, most economic treatments were T 6 (FYM + 50% Nand 100% P
and K as inorganic) and T9 (all the three biofertilizers + FYM + NPK as inorganic) in
Panniyur 1 (BCR - 2.52) and T, (FYM + biofertilizer + inorganic combination) in
Panniyur 2 (BCR - 3.92).
