ABSTRACT
The present investigation entitled “Integrated Nutrient Management Studies in Garlic (Allium
sativum L.)” was conducted during rabi season of 2016-17 at Horticultural Research and Training Station and
KVK, Kandaghat of Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan. Ten
combinations of different organic and inorganic amendments were replicated thrice in the form of ten treatments
in a plot having dimensions of 2.0x2.0m. The experiment was laid out in a randomized block design with three
replications involving a spacing of 20x10cm. The cloves of garlic variety ‘Kandaghat Selection’ were sown on
1st October, 2016. The observations were recorded on plant height (cm), number of leaves per plant, days to
harvest, bulb weight (g), bulb diameter (cm), number of bulbs per kg, weight of 100 peeled and unpeeled cloves
(g), bulb yield per plot (kg) and per hectare (q), number of cloves per bulb, peeling index (%), dry matter
content (%), oleoresin content (%), disease severity (%), NPK content of the soil before start and after
termination of experiment and NPK uptake by the plant, viable count of bacteria present in the soil before start
and after termination of experiment. Benefit to cost ratio (B:C) was higher in T4, however, maximum returns
amounting to Rs 11,76,200 were computed in T9. The results revealed that application of 50% Recommended
FYM (125 q/ha) + 50 % Vermi compost (Equivalent to N content of 50% Recommended FYM) as basal dose at
time of field preparation + Application of Jeevamrut (Fortnight application) + 50% RDF of NPK produced best
results in terms of characters like bulb weight, bulb diameter, number of cloves per bulb, yield per hectare,
weight of 100 peeled cloves, weight of 100 unpeeled cloves, peeling index, oleoresin content, dry matter
content, N content in soil and K uptake by plant, whereas, minimum values for all these characters were
recorded in the absolute control. Application of Vermicompost (Equivalent to N content of Recommended
FYM) as basal dose at the time of field preparation + Application of Jeevamrut (Fortnight application) + 50%
RDF of NPK produced next best results for characters like number of leaves per plant, number of cloves per
bulb, phosphorus content in soil and N and P uptake in plants. No disease was noticed during the course of
studies. It was concluded that Treatment T4{Seed treatment with Beejamrut (overnight) + application of
jeevamrut (fortnight application) + Recommended FYM (250q/ha) as basal dose at the time of field preparation}
which is the most economic treatment, can be recommended to the farmers after verification of results in multi
location trials and thorough testing in the form of OFT in the farmer’s field, while T9 being the best treatment in
terms of yield can also be recommended to the farmers if they reduce the cost of vermi compost by preparing it
themselves at home instead of purchasing from the market and hence, can be recommended for obtaining
maximum yield and returns from garlic crop after repeating the experiment for another two years.
