• The term Spice and Condiments applies to natural plant or vegetable products or mixtures in whole or ground form, which are used for imparting flavour, aroma and piquancy to the food items. • Under the act of Parliament, a total of 52 spices are brought under the purview of Spices Board. • However 109 spices are notified in the ISO list. • India is the largest producer, consumer and exporter of spices and spice products in the world and produces more than 50 spices. • The spices production in India is of the order of 5.74 million MT from an area of about 3.07 million ha. • Chilli is the major spice crop occupying about 25.8 percent of area under cultivation and contributing about 22.7 percent of total spices production in the country. • Garlic accounts for 21.9% of production and 8.1% of area Turmeric accounts for 16.9% of production and 6.3% of area. • Rajasthan occupies major area under spices owing to seed spices cultivation in the state followed by Gujarat, Andhra Pradesh, Madhya Pradesh and Karnataka. • Andhra Pradesh, which is the foremost state producing chilli and turmeric in the country, ranks first in terms of production.

High-yielding crop varieties and hybrids with tolerance to pests /diseases and to various farming constraints such as soil and water salinity, soil acidity, drought, flood and such other factors have been developed. Eight cardamom hybrids, NKE 12 × MB 5 (1,499 kg/ha), MB 5 × NKE 19 (1,461 kg/ha), GG × NKE 12 (1,350 kg/ha), RR 1 × CCS 1 (1,245 kg/ha), CCS 1 × RR 1 (1,022 kg/ha), ASH (1,930 kg/ha), NKE 12 × GG (1,746 kg/ha), GG × NKE 19 (1,635 kg/ha), were identified for high yield and resistance to mosaic and rhizome rot diseases. Two unique mutants, AFg-3 and AFg-4, for powdery mildew resistance were isolated in fenugreek. In ajwain, AA 93 has been developed which flowers 40 days earlier compared to other varieties. Thirty- two elite saffron clones were selected and evaluated for fresh and dry weight of pistil, stiga and style length, and weight. CITH 125 (4.5 kg/ha), CITH 123 (4.3 kg/ha), CITH 124 (4.3 kg/ha), CITH 122 (4.0 kg/ha), CITH 12 (4.5 kg/ha), CITH 121 (3.9 kg/ha), CITH 107 (3.8 kg/ha), CITH 120 (3.8 kg/ha) and CITH 104 (3.7 kg/ha), having higher saffron yield were identified.

Cost-effective farming systems for spices cultivation for increasing production and productivity in different agro ecologies have been developed. An organic package for production of black pepper, ginger and turmeric by applying farmyard manure, vermicompost, ash, rock phosphate, Azospirillum sp. and phosphobacteria and Trichoderma sp. and Pseudomonas sp. as biocontrol agents for disease control was developed. Further, a foliar spray of 1% solution of complex fertilizer 19 : 19 : 19 (N : P : K) during spike initiation period (April second week, May first week and May fourth week) during lean cropping season under irrigated condition enhanced black pepper (cv. Panniyur I) yield by 20–25%. Soil application of zinc up to 10 kg/ ha or foliar spraying of ZnSO4 (0.25%) and Borax (0.2%) twice (60 and 90 days after planting) was recommended for higher yield and quality for turmeric in zinc and boron deficient soil. Among all the treatments, sprinkler and drip irrigation methods caused early sprouting; early flowering with increased plant height and more number of leaves and flowers/plant as compared to the control (rainfed). Also, stiga fresh weight, dry weight, length and saffron yield were improved in sprinkler and drip irrigation methods over the control. Raised beds resulted in early sprouting, early flowering with increased plant height and more number of leaves and flowers/plant.

A protocol for SYBR green based real-time RT-PCRfor detection of Piper yellow mottle virus and Cucumber mosaic virus infecting black pepper and Cardamom mosaic virus (CdMV) and Banana bract mosaic virus (BBrMV) infecting cardamom was developed. A native isolate of Phytophthora capsici (Is. No. 98-93) infecting black pepper was completely sequenced using next generation sequencing platform, Illumina-Solexa GA II. The sequence data was assembled by taking Joint Genome Institute’s P. capsici as reference genome. The treatment of black pepper cuttings with Carbendazim + Mancozeb (0.1%) was effective for the management of anthracnose disease in nursery. The black pepper accession, 1114 (Kumbhachola), was tolerant to P. capsici. The accession was earlier found resistant to pollu beetle and drought. A new bacterial wilt disease on small cardamom was recorded in Wayanad, Kerala. The phenotypic and genetic characterization revealed that causative organism is Ralstonia solanacearum (Biovar 3 phylotype 1) and was 100% similar to ginger strain of R. solanacearum. Bacillus amyloliquefaciens (GRB 35) and Serratia marcescens (GRB 68) were promising for enhancing sprouting of rhizomes, growth promotion and reducing the incidence of soft rot and bacterial wilt diseases in ginger in the field.

Recent Initiatives by National Research Centre on Seed Spices, Ajmer Standardization of the drying techniques In fennel five methods of grain drying were employed viz., shade dryer (30°C), sun dryer (35°C to 37°C), solar dryer (40°Cto 42°C), vegetable dryer (50°C) and multipurpose grain dryer (60°C). Fennel grains which were dried under solar dryer, gave maximum test weight (5.17 g), recovery (39.82 %) with lowest moisture content (61.30%) and highest taste marks (9.3) and colour marks (9.2).

Common name, symptoms of damage and management of diseases of major spices and condiments

The term plantation crops refer to those crops which are cultivated on an extensive scale in contiguous area, owned and managed by an individual or a company. There are two groups of plantation crops namely coconut, arecanut, oil palm, cocoa, cashewnut dealt by Ministry of Agriculture and tea, coffee, rubber dealt by the Ministry of Commerce. These are high value commercial crops of greater economic importance and play a vital role in improving Indian economy, especially in view of their export potential, employment generation and poverty alleviation particularly in rural sector.

High-yielding Plantation crops varieties and hybrids with tolerance to pests / diseases and to various farming constraints such as soil and water salinity, soil acidity, drought, flood and such other factors have been developed. Three coconut varieties (IND 045S, IND 048S and IND 058S), two arecanut varieties (VTL 62-Shriwardhan selection and VTL7-Nalbari) and two selections of cocoa (VTLC 1 and VTLC 57) were identified for commercial cultivation. Coconut variety, Kalpa Samrudhi, was recommended for commercial cultivation in Kerala and Asom, and Kalpa Sankara and Kalpasree for coconut root(wilt)- affected tracts in Kerala. Molecular-markers associated with hybridity in coconut, dwarfness and resistance to root (wilt) and yellow leaf diseases were utilized. Homology-basedmodelling of somatic embryogenesis receptor-like kinase (SERK) protein in coconut, development of a computational tool for detection of microsatellites in whole genome sequences, development of algorithm for gene annotation and genome-wide analysis of microsatellites in strains of plant growth promoting (P. fluorescens) are achievements in bioinformatics.

Cost-effective farming systems for plantation crops cultivation for increasing production and productivity in different agro ecologies have been developed. In coconut-based cropping system, elephant-foot yam cv. Gajendra yielded high amount of corm. Guinea grass (var. GGCo 3) produced higher green fodder (89.2 tonnes/ ha/year) under husk application. There was lower specific volume of soil and soil porosity (higher soil compaction), and soil dehydrogenase activity (an index of biological activity) as important abiotic pre-disposing factors in incidence of root wilt disease. Growing Gomphrena globosa as intercrop in root wilt- affected coconut gardens has been shown to be cost-effective and sustainable. In areca-based mixed farming system, total cash inflows and outflows from arecanut + dairy (3–4 milch cows) amounted to ‘4.41 and ‘5.96 lakh, with a net profit of’1.55 lakh. The system productivity of arecanut + cocoa system (3,127 kg/ha) was 30% higher per unit area than arecanut alone (2,405 kg/ha). Integrated nutrient management on four improved arecanut varieties recorded highest chali yield (4.19 kg).

Crop protection research has brought out tangible and effective methods to suppress various pests in major agro-ecosystems. Indigenous knowledge in this regard has been tested and validated for its suitability. Among the 137 Phytophthora isolates collected from bud rot/fruit rot affected coconut gardens in Tamil Nadu, Kerala and Karnataka, four isolates from bud rot affected gardens were identified as P. nicotianae and one as P. capsici. Since, P. nicotianae is found associated with bud rot disease of coconut in three districts representing three states, it is expected that this may emerge as a major pathogen of coconut. Further, placing Trichoderma coir pith cake in the innermost leaf axils of coconut palm in disease endemic areas just before the onset of southwest monsoon (May-end) and thereafter at two months interval was found to be very effective in the management of bud rot disease of coconut.

Technique to collect fresh and hygienic inflorescence sap (Neera) from coconut In the traditional method of collecting sap, the inflorescence to be tapped is connected with an earthen pot/bamboo receptacle for the sap collection. Spadix to be tapped is tied with plastic rope and a small portion is sliced off from the top. The spadix is gently stroked with a mallet in the morning and evening. After a period of 8 to 10 days, sufficient sap starts oozing out from the cut end. A type of clay soil, a gummy material or leaf extract is pasted on the surface and sides of the cut end. Since the sap is highly nutritious, both enzymatic and microbial fermentation takes place. The total sugar reduces progressively and it becomes more acidic and develops a harsh odour and becomes unpalatable. In order to prevent fermentation, lime is coated inside the pot. The above method is not hygienic and attracts lot of insects, ants and contaminates from pollen and dust particles. In order to collect the sap fresh and hygienic, a simple device was developed.

Introduction Medicinal Aromatic Plants (MAPs) play a valuable and important role in economic, social, cultural and ecological aspects of local communities the world over. According to World Health Organization (WHO) “a medicinal plant is plant which, in one or more of its organs, contains substance that can be used for therapeutic purpose, or which are precursors for chemo- pharmaceutical semi-synthesis”. However, a simplest definition of the medicinal plant would be “Medicinal plants are those plants which are used in official and various traditional systems of medicines throughout the world”. Other definition could be “Medicinal plants are plants that provide people with medicines - to prevent disease, maintain health or cure ailments”. In Indian traditions, all the plants in this earth are considered as medicinal [Jivak in Astanga Hriday (Sutra: 9-10)]. Aromatic plants are a special class of plants used for their aroma and flavour. Many of them are exclusively used also for medicinal purposes in aromatherapy as well as in various systems of medicine.

A high-yielding cultivar Vallabh Medha of mandukparni (Centella asiatica) was identified. Fresh herbage yield (12,331 kg/ha) and dry herbage yield (2,113 kg/ ha) of this variety were far more than the local variety (2,050 and 392 kg/ha respectively), besides higher active ingredients. Among mucuna selections, IIHR PS 15 with long duration, IIHR PS 6 with medium duration and IIHR PS 14 with short duration recorded significantly higher yield and high L-dopa yield/ plant. In Coleus, a promising hybrid, Hy 08-53, recorded significantly higher root yield (60.22g) and higher forskolin yield/plant (0.58 g). In ashwagandha, IIHR- WS 3 was found to be the best yielder (11.65 q/ha).

Isabgol (Plantago ovata Forsk.) The crop requires cool and dry climate during the growing season. Sowing of seeds at 4 kg/ha in 0.25-0.50 cm depth during November 20 to December 20 was recommended. In medium black cotton soil of Malwa region, second week of November was reported to be optimum time for sowing. Broadcasting of seeds followed by light sweeping with broom found to give uniform germination. A spacing of 30x 45 cm found to be most ideal to get higher seed yield in Isabgol under Madhya Pradesh situation. Response of chemical fertilisers was found low. However, a fertiliser dose of 25 kg/ha each of N and P2O5 as basal dose and 25 kg/ha N as top dressing at 30-42 DAS was recommended for commercial cultivation in Gujarat while 50 kg/ha N reported to increase the seed yield in Madsaur areas of Madhya Pradesh. At Anand three irrigations viz. first at the time of sowing and subsequently at 30 and 70 days after sowing (DAS) proved to be beneficial. However, four irrigations at sowing, 10,25, and 50 DAS at Mandsaur are recommended. Chemical weed control was found to be economical and a pre-sowing or pre-emergence application of Isoproturone (0.5 kg ai/ha) was recommended for weed control. One spray of Metalaxyl + two sprays of Mancozeb were found significantly superior in controlling downy mildew. In Gujarat, Pearl millet in Kharif and Isabgol in Rabi season are advocated as a suitable crop rotation. Groundnut-Isabgol rotation gave higher economic return followed by Soybean-Isabgol and Pigeon pea-Isabgol rotations in Maharashtra.

Azadiractin (1%) was found effective for the control of Hadda beetle on Ashwagandha. Nineteen arthropods were recorded on isabgol. Among them, 13 were phytophagous species belonging to order Lepidopteran (09), Hemipteran (03) and Homopteran and six predatory species belonging to order Coleoptera (03), Neuroptera (01) and Odanata (02). The sequential occurrence of arthropods revealed the presence of aphid (Aphis gossypii) from second week of January to fourth week of February, whereas Lepidopteran (Helicoverpa armigera, Trichoplusia ni, Thysanoplusia oricalchae, Spliarictia sp. Hyposidra successari and Olene mendosa and true bugs (Graptostethus servus and Spilostethus pandurus) were observed associated during early crop growth stages (i.e. from second week of December). Infestation of aphid was uniformly severe, whereas that of Lepidopterans and true bugs were sporadic and less severe. However, presence of these pest arthropods caused significant reduction in seed yield.
