The plant produced 24.75 g of fruit given positive energy, while the plant with negative thought energy produced 22.12 g of fruit. The fruit and seed weight increased by 11.88% and 13.63%, respectively, due to positive energy. The number of fruit retentions increased by 23.77% due to positive energy. Anthocyanin content in pericarp was increased by 5.45% in plants given positive energy. Fruit qualities were also significantly affected by psychoenergy. TSS (Brix) was significantly increased by 13.54% in plants given positive energy as compared to negative energy, and titratable acidity was reduced by 25% due to positive energy. Ascorbic acid was also increased by 30% in plant given positive thoughts. Sun burn was reduced by 54.76% and fruit cracking by 63.64% due to energy of thought. Fruit borer...

Combined use of organic manures and biofertilizers (PSB + AZB) registered head yield at par to control (RDF). The result revealed that growth and yield attributing characters were significantly influenced by the application of different nutrient sources. The highest plant height (19.47 cm and 25.22 cm), number of leaves at different stage 20 & 40 DAP (9.9 and 12.38) and plant spread (52.15 cm) were reported under T10. The maximum number of wrapper leaves (40.83), non-wrapper leaves (11.50), stalk length (7.28 cm), overall plant weight (0.790 kg), head diameter (13.52 cm), head weight (0.54 kg), and yield/ha (23.35 t/ha) were recorded under treatment T10 which was at par with T4. Other parameters viz., weight of non-wrapper leaves (164.16g), root length (33.75 cm), maximum root fresh (42.01g) and dry weight (8.7g) and compactness of head (28.00) were recorded highest under the treatment T4. However, highest dry matter content (6.87%) was recorded under T6. The highest head to root ratio were recorded under T10 (14.36) which was at par with T4 and T8. All the growth parameters were significantly poor under biofertilizers (PSB + AZB) inoculated treatment. However, highest harvest index was recorded under T10 (55.05%) which was at par with T4, T7, T8 and T3.

Fourteen genotypes were affected by sun burn with maximum in genotype IC-0615602 (54.48%). Sixteen genotypes were free from sun burn which possessed maximum cuticle thickness ranging from 1.99 mm in IC-0615585 to 1.95 mm in IC-0615595 whereas susceptible genotypes possessed least thickness of cuticle. Tolerant genotypes possessed maximum fruit skin strength, number of leaflet per shoot, densely spaced leaflet, minimum length of rachis and petioles. Fruit Surface Temperature (FST) of susceptible genotypes was higher than that of tolerant genotypes. Fruits located in the south direction were highly affected to sun burn to the tune of 62.45 % whereas north direction showed least (43.46 %). Positively correlation of sun burn was found with FST (0.83), leaflet interval (0.69), petiole length (0.49) and negatively correlation with cuticle thickness (-0.69), spongy layer thickness (-0.79), fruit skin strength (-0.68) and total leaflet (-0.65).

The larval population of P. pulvereaand E. amabilis are absent in month of September 2015, January and February 2016. Mean monthly population (Larvae + Pupae) of P. pulverea and E. amabilis were recorded in August 2015 to February 2016 from the (50) g stored lac samples. P. pulverea was absent in samples of stored lac collected during the month of September 2015, January and February 2016 in all storage structures. The mean (larval + pupal) population of P. pulverea was highest (7.67) in month of November 2015 followed ...

In this review, traditional value, nutritional composition, bioactive compounds and other uses have been focused. Longan fruits are very tasty and its organoleptic qualities are unique because fruit has a succulent, edible and white aril, which has gained popularity. Longan fruits have immense potential in food and pharmaceutical industries. Longan aril, peel and seed extract have anti-glycated, anti-tyrosinase and anticancer properties, and memory enhancing effects which contribute to healthy human health. In China, the entire area of litchi is shifting to longan, which indicates the importance of longan crop and free from production barriers (poor fruit set, fruit drop, sun burn, fruit cracking, insect and pests) in longan cultivation make it popular among the peoples in India. This review will highlight the uses of longan for different purposes.

Shahi. The study revealed that the temperature, flowering stage as well as length of inflorescence were positively correlated with florescence width (0.98) while fruit set was negatively correlated with temperature (-0.863). There was a strong correlation between fruit set and size of the inflorescence. Early-season flowering had higher fruit set (8.56%) as compared to mid (7.58%) and late-season (4.05%) flowering. Fruit set was critically reduced by 50% in late floweringplants resulting in drastic reduction in the total fruit yield. A strong positive correlation (0.84) was found between inflorescence hickness and fruit weight. Fruit and pulp weight were influenced by stage of flowering, as early flowering exhibited highest fruit weight (24.56 g) compared to mid and late flowering ...

Shahi was investigated. The litchi cv. Shahi, planted in square system at 2 × 2, 3 × 3, 4 × 4, 5 × 5, 6 × 6 and 8 × 8 m (control), showed average light interception higher in the upper part of the canopy. Flowering and yield attributes (number of panicles, panicle length, number of flowers and fruit yield/plant) were obtained maximum in wider spaced trees (8x8 m) while fruit yield kg/plant was recorded maximum in 6x6 m in square system of planting. Fruits harvested from 8x8 m trees were superior in fruit quality (fruit length, weight, diameter, total soluble solids, organoleptic score, TSS: Acidity). Biochemical parameters and leaf nutrient content (total phenol, N, P, K and total chlorophyll, total sugar) were recorded maximum in 8x8 m. Hence, 8x8 m planting space can be recommended to the farmers for better yield. Ban...

Coefficients of variation for length and width of panicle, number of primary and secondarydichasia, maximum length of primary and secondary dichasia, maximum and minimum distance between twoprimary dichasia and origin of number of primary dichasia (primary branches on panicle) from same point,filament length, length and diameter of anther, number of fruits/cluster and yield/ plant were more than 20%.The number of secondary dichasia was highly correlated with the length of stigma. Similarly, number of fruitsper cluster and yield, and fruit weight and thickness of pedicle were also correlated. Genotypes were dividedinto two main groups which corresponding to the size of the panicle and yield. Cluster-I contained genotypesof comparatively small panicle with lower yield, while cluster-II is composed of larger panicle with higheryield. From variability analysis, le...
