Garlic

https://agri.bot/crop-calendar/garlic

Garlic (Allium sativum) is India's third-largest bulb spice by area after onion and ginger: about 460,000 – 520,000 hectares produce roughly 3.3 – 3.6 million tonnes a year, making India the world's second-largest producer after China. Madhya Pradesh is the clear leader with ~55 – 60% of national production — the Malwa plateau (Ratlam, Mandsaur, Neemuch, Ujjain, Shajapur, Rajgarh) is the single largest garlic cluster in India and the Mandsaur and Neemuch APMC mandis are the national price benchmarks tracked on Agmarknet. Rajasthan (Hadoti belt — Kota, Baran, Jhalawar), Gujarat (Saurashtra), Uttar Pradesh (Ganga-Yamuna doab), Punjab and Odisha together make up most of the rest. India also carries two GI-tagged specialty garlics: Kishtwar garlic (Jammu & Kashmir — a cold-desert, single-clove, pungent hill garlic) and Nabarangpur Kandhamal garlic (Odisha tribal belt — a long-storing white-bulb variety). The nodal ICAR research institute is the Directorate of Onion and Garlic Research (ICAR–DOGR) at Rajgurunagar near Pune, Maharashtra, with the AICRP on Spices network led by ICAR-NRCSS Ajmer coordinating multi-location trials. Garlic is a scheduled spice under the Spices Board of India (Kochi) which handles export promotion, and APEDA Agri Exchange tracks the HS 07032000 shipment data.

Twelve-month operations

Fertilizer schedule

A medium-input bulb crop. ICAR-DOGR Rajgurunagar and AICRP on Spices (NRCSS Ajmer) package of practices recommend approximately 100 kg N + 50 kg P₂O₅ + 50 kg K₂O + 20 kg S per hectare for the irrigated plains rabi crop (increased to 120-60-60 on the Malwa heavy clay-loam blocks of Ratlam / Mandsaur / Neemuch). Apply full P, K and S plus one-third of nitrogen as basal at clove sowing (incorporated 10 – 15 cm deep). Top-dress remaining nitrogen in two splits — one-third at 30 DAS (3 – 4 leaf stage) and one-third at 60 – 70 DAS (bulb initiation). Garlic is highly responsive to sulphur: 20 – 40 kg S/ha from gypsum or elemental sulphur sharply improves pungency (allicin content), bulb weight and the storage life that the Malwa and Hadoti trade depends on. Apply 15 – 20 t/ha of well-rotted FYM at ploughing. Boron (1 kg B/ha as borax) and zinc (25 kg ZnSO₄/ha once in three years) on sandy Malwa / Mandsaur / Neemuch blocks correct hollow-bulb and small-bulb disorders. Avoid heavy nitrogen after 70 DAS: it delays maturity, inflates necks (thick-neck disorder, hard to cure) and reduces storability.

Pest & disease management

Thrips (Thrips tabaci) are the single most damaging insect pest — they rasp leaf tissue, give silvery streaks and are the vector for Iris Yellow Spot Virus (IYSV, which has emerged on Mandsaur / Neemuch and Hadoti blocks since the mid-2010s). Manage with blue sticky traps, need-based fipronil, lambda-cyhalothrin or spinosad sprays rotated across modes of action, and avoid onion-garlic sequential planting on the same block. Stemphylium leaf blight (Stemphylium vesicarium) and purple blotch (Alternaria porri) are the major foliar diseases on dense Malwa blocks — spray mancozeb (0.25%) or hexaconazole + mancozeb combi at 10 – 15 day intervals from 45 DAS onwards. Basal rot / white rot (Sclerotium cepivorum, Fusarium oxysporum f.sp. cepae) is a devastating soil-borne disease on continuous garlic / onion blocks — manage with Trichoderma viride enriched FYM (2 – 4 kg/t FYM), carbendazim clove dip (0.1% for 15 min), 3 – 4 year rotation out of alliums and summer deep ploughing on sick fields. Nematodes (Ditylenchus dipsaci — the stem and bulb nematode) are a quarantine concern on exported planting material. Rodent damage to curing bulbs in heap-cured stores is a storage pest on Malwa and Hadoti blocks.

Irrigation

Garlic needs 10 – 14 light irrigations in total for a plains rabi crop. A pre-sowing irrigation is standard, followed by irrigations every 7 – 10 days for the first two months (shallow root system, high surface-moisture demand) and every 10 – 15 days thereafter. Critical stages: 25 – 30 DAS (sprouting-establishment), 50 – 60 DAS (bulb initiation — water stress here halves bulb size), 90 – 110 DAS (rapid bulb-fill) and 120 – 140 DAS (bulb maturation). Stop irrigation 10 – 15 days before harvest to firm up bulbs and improve cure quality. Avoid heavy flood irrigation or standing water at bulbing stage: this triggers purple blotch, basal rot and splitting / scaling disorders. Drip-fertigation on raised beds (replacing flood on heavy Malwa clay-loams) gives 25 – 35% water savings and 15 – 20% yield gains and is subsidised under MIDH / PMKSY–Per Drop More Crop on commercial Ratlam / Mandsaur / Neemuch and Hadoti blocks. Rainfed Malwa blocks on residual soil moisture give 2 – 4 t/ha of fresh bulbs; irrigated commercial blocks give 8 – 15 t/ha of fresh bulbs or 5 – 10 t/ha of cured bulbs.

Frequently asked questions

Why is the Malwa plateau (Mandsaur, Neemuch, Ratlam) India's dominant garlic belt?

The Malwa plateau in western Madhya Pradesh — centred on Mandsaur, Neemuch, Ratlam, Ujjain, Shajapur and Rajgarh districts — accounts for roughly 55 – 60% of India's garlic production from around 250,000 – 300,000 hectares. The dominance is a combination of agro-climate, soils, water and market infrastructure. The plateau sits at 400 – 600 m elevation with mean rabi (Nov – Mar) temperatures of 10 – 28 °C — close to the agronomic optimum for Allium sativum bulb-initiation (which requires 8 – 20 °C night temperatures and 15 – 24 °C day temperatures through November to January). The deep medium-black Malwa soils (Vertisols and Vertic Inceptisols) have the moisture-retention capacity to support a 140 – 170 day shallow-rooted crop with only 10 – 14 light irrigations, and the pH range (7.0 – 8.0) suits garlic without major amendment. The Narmada and Chambal command-area irrigation plus private tubewells have built out dense bore-well-and-sprinkler infrastructure since the 1990s. The Mandsaur, Neemuch and Ratlam APMC mandis grew into specialised garlic cleaning, sorting, drying-yard and heap-storage ecosystems; Mandsaur alone handles 2 – 4 lakh tonnes of garlic arrival a year and is the national price benchmark on Agmarknet. Finally, the Delhi – Mumbai – Nagpur rail and road corridor through Ratlam connects Malwa garlic to the Azadpur (Delhi), Vashi (Navi Mumbai), Koyambedu (Chennai) and Yashwanthpur (Bengaluru) wholesale markets within 24 – 36 hours, which is why Malwa garlic sets the national spot price.

Which garlic varieties are grown commercially in India, and what does DOGR Rajgurunagar coordinate?

The ICAR Directorate of Onion and Garlic Research (DOGR) at Rajgurunagar near Pune, Maharashtra is India's nodal R&D institute for onion and garlic — it coordinates the AICRP on Allium crops and the varietal pipeline that reaches state horticulture departments and farmers. Commercial Indian garlic varieties fall into three broad groups: (1) short-day, warm-climate, large-bulb white garlics for the plains — the DOGR Bhima series (Bhima Omkar, Bhima Purple), Yamuna Safed series (G-1, G-2, G-3, G-4, G-5, G-50 — the dominant Malwa / Hadoti commercial garlic, released by IARI New Delhi and DOGR), Agrifound Parvati, Agrifound White and Agrifound Shweta (NHRDF Nashik), GG-3 and GG-4 (Gujarat series — Junagadh), and the local Mandsaur / Ratlam / Neemuch desi types; (2) short-day, warm-climate, pink / red / purple garlics — Agrifound Parvati (NHRDF), DOGR Bhima Purple; (3) long-day, cold-climate, specialty hill garlics — the GI-tagged Kishtwar Garlic (Jammu & Kashmir — a cold-desert single-clove / small-clove, intensely pungent variety grown in Padder valley at 1,700 – 2,000 m, with an allicin content 2 – 4× the plains average) and the GI-tagged Nabarangpur Kandhamal Garlic (Odisha — a long-storing tribal-belt white-bulb variety grown by the Bhumia, Paroja and Gond communities). DOGR also runs the National Seed Project (Horticulture) for breeder-and-foundation seed of alliums through state seed corporations, NHRDF Nashik and the Spices Board cluster seed-production programme, and coordinates research on Iris Yellow Spot Virus (IYSV) resistance, thrips IPM, basal-rot management (Fusarium / Sclerotium) and the drip-fertigation package of practices on raised-bed blocks.

What makes Indian garlic distinctive in export markets, and how is the trade regulated?

India exports 40,000 – 90,000 tonnes of fresh and dried garlic a year — a small share of production (China dominates global trade with 70 – 80% of exports) — primarily to Malaysia, Vietnam, Nepal, Bangladesh, Sri Lanka, UAE, Thailand, Oman and the US. Indian garlic competes on three attributes: the Malwa plateau white-bulb grade (medium-to-large bulbs with 10 – 15 cloves per bulb, white papery skin, 6 – 8 month shelf-life after proper curing) is positioned against Chinese Jinxiang garlic in Southeast Asian markets, often at a 10 – 20% price discount; the Hadoti and Saurashtra bold-bulb grades are preferred in the Middle East for whole-garlic processing; and the specialty GI-tagged Kishtwar single-clove garlic commands a 5 – 10× premium in ayurvedic, pharmaceutical and gourmet markets for its high allicin and sulphur-compound content. Garlic is a scheduled spice under the Spices Board of India (Kochi) — commercial exporters must hold a Spices Board exporter registration (CRES) in addition to the DGFT-issued Import Export Code and must comply with Spices Board quality parameters (moisture, mould, pesticide residue MRL) under the Spice House Certificate programme. APEDA Agri Exchange tracks HS 07032000 shipment data. The GI tags of Kishtwar Garlic (registered 2019) and Nabarangpur Kandhamal Garlic (registered 2019) are held by producer co-operatives under the GI Act 1999 and are promoted by APEDA and the respective state horticulture departments for premium-market branding.
