ABSTRACT
The present investigation entitled “Studies on the Effect of Seed Pelleting and Integrated Nutrient
Management in Bell Pepper (Capsicum annuum L.) was carried out in the laboratory and khaltoo experimental
farm of Department of Seed Science and Technology, Dr YS Parmar University of Horticulture and Forestry,
Nauni, Solan HP during Kharif season for two consective years (2016-17 and 2017-18). The present research
programme was carried out in two phases. In first experiment the seeds of bell pepper cv. Solan Bharpur were
pelleted with NPK (19: 19: 19), Multiplex, Potassium dihydro orthophosphate (KH2PO4), Zinc sulphate
(ZnSO4), Boric acid (H3BO3), Magnesium sulphate (MgSO4), Copper sulphate (CuSO4), NPK (19: 19: 19) +
Multiplex, NPK (19: 19: 19) + KH2PO4 , NPK (19: 19: 19) + ZnSO4 , NPK (19: 19: 19) + (H3BO3), NPK (19:
19: 19) MgSO4, NPK (19: 19: 19) + CuSO4, Wood ash, Control (unpelleted seed). NPK and multiplex were used
@ 5 gm/kg seed, all other micronutrients were used @ 300 mg/ kg of seed and wood ash was used @ 3000 g/kg
of seed and tested for seed germination and vigour under laboratory and nursery conditions. It was found that
seed pelleted with zinc sulphate produced best results for characters like germination, seedling length, seedling
dry weight, seedling vigour index-L and seedling vigour index-M under laboratory and nursery conditions,
whereas maximum speed of germination was recorded in unpelleted seeds under nursery conditions. Three best
pelleting treatments i.e. Zinc sulphate, dihydro orthophosphate and Boric acid were shortlisted from experiment1
for further field studies. The second experiment was carried out under open field conditions in two sets
seperately, set-1 for fresh market fruit crop and set-2 for seed crop. Three best pelleting treatments (as recorded
in experiment-1) alongwith unpelleted control combined with six INM treatments i.e. recommended dose of
NPK (100:75:75 kg/ha), Azotobacter (2.5 kg/ha) + PSB (2.5 kg/ha) + KSB (2.5 kg/ha), Azotobacter + PSB +
KSB + 90% recommended dose of NPK, Azotobacter + PSB + KSB + 80 % recommended dose of NPK,
Azotobacter + PSB + KSB + 70% recommended dose of NPK and Azotobacter + PSB + KSB + 60 %
recommended dose of NPK. Biofertilizers were applied as seedling dip at transplanting and soil application. In
the set- I (fresh market crop), seeds pelleted with zinc sulphate + application of Azotobacter + PSB + KSB + 80
% recommended dose of NPK produced maximum values for characters like plant height, harvesting duration,
fruit weight, fruit length, fruit width, number of fruits/plant, fruit yield/plant, fruit yield/plot, fruit yield/ha,
whereas, same treatment produced minimum values for days to 50 % flowering and days to fruit harvesting. In
the set- II (seed crop), again the seed pelleted with zinc sulphate + application of Azotobacter + PSB + KSB +
80 % recommended dose of NPK produced maximum values for characters like ripe fruit weight, ripe fruit
length, ripe fruit width, number of ripe fruits/plant, ripe fruit yield/plant, number of seed/fruit, seed yield /plant,
seed yield/plot, seed yield/ha, 1000 seed weight, germination, seedling length, seedling dry weight, seed vigour
index-Length, seed vigour index-Mass, whereas, same treatment produced minimum days to fruit harvesting.
Seeds pelleted with potassium dihydro orthophosphate + application of Azotobacter (2.5 kg/ha) + PSB
(2.5 kg/ha) + KSB (2.5 kg/ha) + 80 % recommended dose of NPK (P3N4) produced minimum ripe fruit rot
incidence. Therefore, seed pelleting with zinc sulphate @ 300 mg/kg seed + application of Azotobacter + PSB +
KSB as seedling dip at transplanting and soil application + 80 % recommended dose of NPK can be
recommended for getting higher yield of fresh fruits as well as seed crop of bell pepper in Himachal Pradesh.
