An attempt has been made to explore the possibilities of commercially important by value addition underutilized fruits of Andaman and Nicobar. The Andaman and Nicobar Island have a wide variety and diversity of tropical underutilized fruit tree species especially belonging to family Anacardiaceae, Pandanaceae, Myrtaceae, Anonaceae and Combretiaceae. Many of the species belonging to these families can withstand in adverse climatic and edaphic conditions, so could be used for growing in wasteland. These fruits are rich in vitamins, calcium and minerals and have high medicinal properties in comparison to other tropical fruits. These fruits could be processed for making value added products like Jams, jellies, syrup, chutney and pickle. The continuous overexploitation of forest resources resulting in many species has become rare and few endangered, so conservation measures for these species is urgently required.Keywords

Due to typical tropical climate and congenial ago-climatic conditions of the zone, a large number of fruits, vegetables, orchids, spices and medicinal and aromatic plants are found growing in one or other parts of these countries. Among the fruits, the important ones are: Soursop (Anona muricata), Mangosteen - Garcinia mangostana (one of the finest and tastiest tropical fruit of the world), Durian (Durio zibethinus), Avocado (Persea americana), Tamarind (Tamarindus indica), Rambutan (Nephelium lappaceum), Breadfruit (Artocarpus altilis), Bael (Aegle marmelos), Jack fruit (Artocarpus heterophyllus), loquat (Eriobotrya japonica), Sapota (Achras zapota) etc. Similarly, the vegetables include Curry leaf (Murraya koenigii), Drumstick (Moringa oleifera), Yam (Dioscorea alata), Taro (Colocasia antiquorum), Sweet potato (Ipomoea batatus), Bamboo (Bambusa vulgaris), Tapoica (Manihot esculenta), Chekkurmani (Sauropus andogynus) and a number of other leafy vegetables, which are growing throughout the year. The region is rich in a vast diversity of orchids, which are growing as epiphyte and terrestrial. The important orchids, which are available in this region and can be exploited, are Cymbidium aloifolium, Dendrobium formosum, Cattleya sp., Eria andamanica, Pholidota imbricata, Rhynchostylis etusa, Vanilla andamanica etc. In the world market, the essential oils play an important role. Some of the plants like Geranium (Pelargonium graveolens), Jasmine (Jasminum grandiflorum), Vanilla (Vanilla planifolia), Patchouli (Pogostemon patchouli) etc. can be grown successfully as intercrop between the arecanut or coconut plantations. These horticultural crops will help to overcome the problem of food and nutritional security with conserving the soil in Andaman and Nicobar islands.Keywords

The present experiment was carried out at Sam Higginbottom Institute of Agricutlure, Technology and Sciences, Deemed University, Allahabad, U.P to study the effect of different sources and levels of nitrogen on physico-chemical characteristics of papaya cv. COORG HONEY DEW. The experiment was laid out in a Randomized Block Design with seven treatments consisting of nitrogen (T1=150g, T2=250g and T3=350g per plant per year as urea), nitrogen (T4=150g, T5= 250g and T6= 350g per plant per year as ammonium sulphate) and T0=control (no application of fertilizers), each treatment was replicated four times. The maximum length of fruits (26.57 cm), width of fruits (47.65 cm), specific gravity (0.88) was noted under treatment T2 followed by treatment T6. The maximum total soluble solids (13.5 %) were noted under the treatment T4 followed by treatment T5 and treatment T1. The total sugar (12.5%) and titrable acidity (0.15%) was recorded maximum with the treatment T1 followed by treatment T4. The maximum ascorbic acid content (50mg/100g) was noted under treatment T1 followed by treatment T6. The maximum pH (5.6) of papaya fruit juice was recorded under treatment T1 followed by treatment T0.Keywords

The Neyveli field is well known for Tertiary lignite deposits in India. The reflectance of organic constituents (humioite macerals) has been measured to find out organic maturation level (rank) of the main lignite seam lying either at same time level or at different time levels in space. The deposits are of sub-bituminous C stage (ASTM) with the mean refectance (Ro max. in oil) range from 0.34 to 0.42% (average 0.39%). Evidences from rank study indicate that the quality of lignite deteriorates towards southern part of the field.Keywords

Pre-harvest application of calcium chloride (0.5, 1.0, and 1.5 %) and gibberellic acid(10, 20 and 30 ppm) at 80% blooming, fruit-set and at 15 days before harvest were carried out on 5-year old trees of apricot cv. Harcot. All the treatments significantly reduced physiological loss in fruit weight, fruit diameter and spoilage percentage during storage. However, CaCl2 @ 1.5% was found to be most effective in minimizing weight loss in fruits during storage compared to Control. Fruits quality (TSS, titrable acidity, TSS/TA, ascorbic acid, total sugar, etc.) was also found to be better (even at 8 days of storage at ambient condition with this treatment) compared to Control. Hence, it can be concluded that pre-harvest foliar application in apricot cv. Harcot with CaCl2 @ 1.5% at three stages, i.e., 80% blooming, at fruit-set and 15 days before harvest, enhances shelf-life of the fruit from 3-5 days storage to 8 days storage, and can maintain good fruit quality under ambient storage-condition for up to 8 days.Keywords

The present investigation was conducted to determine heterosis in 6 lines and 4 tester crosses of bitter gourd, where the six lines used were MC-84 (L1), S-17 (L2), JMC-21 (L3), NDBT-15(L4), VRBT-94 (L5) and Gy-1 (L6) and the four testers were VRBT-6-9 (T1), JMC-22 (T2), VRBT-89 (T3) and MC-56 (T4). Most of the crosses failed to manifest significant heterosis for many of the horticultural traits but traits, like vine length and fruit length showed positive significant heterosis, while, days to first appearance of female flower manifested negative significant heterosis in several crosses. Two crosses, namely, MC-84 x VRBT-6-9 and MC-84 x JMC-22 were identified to have potential in terms of yield, whereas two more crosses viz., S-17 x VRBT-6-9 and S-17 x JMC-22 were found superior in terms of powdery mildew resistance.Keywords

The variance analysis for 17 plant characters showed significant differences. Maximum vine length was recorded in IC-85635A. Significantly higher number of primary branches per vine and internodal length were observed in IC-85639. Maximum number of nodes was observed in JMC-4. Significantly minimum number of days for first appearance of male flower and maximum fruit length, fruit width, yield per vine, yield per plot, yield/ha were recorded in MC-84. Highest number of fruits per vine was recorded in GY-I and minimum powdery mildew infestation was observed in JMC-22.Keywords

Studies were carried out to find out association between different characters and magnitude of association of different characters with gross fruit yield (kg/plant) in ten cultivars of pomegranate (Punica granatum L.) including one local check. Data revealed that genotypic correlation coefficients were higher than their corresponding phenotypic ones for most of the characters, implying an inherent relationship among them. Fruit weight, fruit diameter, fruit volume, juice content, fruit set and number of fruits/plant exhibited highly significant positive correlation. Among the characters studied, number of fruits/plant, fruit weight, fruit volume and fruit set recorded maximum positive direct effect towards gross fruit yield (kg/plant) at both the levels. This study revealed that both the number of fruits/plant and fruit weight could form a selection criterion for yield improvement in pomegranate.Keywords
