The field experiment on Influence of Vermicompost and PSB on growth and carboxylation efficiency of custard apple (Annona squamosa L.) cv. Raidurg was carried out at Fruit Research Farm, Department of Fruit Science at College of Horticulture and Forestry, Jhalawar (Rajasthan) during study period from October 2014 to April 2015. The experiment consisted of different doses of Vermicompost (2kg/plant, 4kg/plant and 6kg/plant) along with PSB (25g/plant, 50g/plant and 75g/plant) and its combination. The results revealed positive correlation of photosynthesis with increase in no. of shoots/branch; increase in canopy volume and percentage increase of scion girth under interactive effect of Vermicompost @ 6kg + PSB 75g/plant .The result showed that maximum per cent increase in East-West (18.22%), North-South spread (17.83%), plant height (18.34%), canopy volume (34.50%), leaf length (29.36%) as well as leaf width (25.77%), increased number of shoots (15.78), scion girth (8.28%), rootstock girth (8.51%) and relative water content (73.71%) were recorded under T15 treatment i.e. Vermicompost@ 6kg + PSB 75g/plant. The carboxylation efficiency parameters were also observed maximum in respect of photosynthetic rate(5.60μmol CO2m2s1), photosynthetic active radiation (1608.33mmol m2s1), stomatal conductance (14.67 m mol m2s1), leaf temperature (38.13C), relative humidity (5.84%), internal CO2 concentration (284.67ppm), transpiration rate (1.33 mmol m2s1), and minimum vapour pressure deficit (47.80 mb) were noted under T15 treatment (Vermicompost 6kg + PSB 75g/plant).

The present investigation was carried out to explore the possibility of peach genotypes grafted on peach seedling rootstocks for their phenological traits to elucidate the desirable genetic stuff. Twenty one genotypes including released varieties, land races and introductions were used in this study for assessment of the traits for yielding the better one through procreation. The study was conducted from 2011 to 2013 at orchard of Department of Fruit Science, PAU, Ludhiana, Punjab. A significant variation was recorded between the traits viz., leaf length (LL), leaf breadth (LB) and leaf area (LA) among different peach genotypes. Leaf length was maximum (156.83 mm) in Tropicsweet and minimum in Redhaven (94.83 mm). The flower size (FS) was recorded maximum (44.00 mm) in genotype Shan-i-Punjab whereas the minimum was in genotype Punjab Nectarine (18.50 mm). Leaf length showed highest (r=0.71) correlation with leaf breadth, whereas, leaf breadth was positively and significantly correlated with leaf area , flower disc size, style number but negatively and significantly correlated with number of filaments, filament and style length. Hierarchical cluster analysis obtained by using DAR win 5.0 software allowed the assessment of dissimilarity relationship among the peach genotypes. The boots trap for each of the genotypes for different characters was run for 5000 times which confirmed the authenticity of similarity and dissimilarity among them. UPGMA produced Dendrogram initially have three main clusters, cluster B being the largest having 9 genotypes.

A field trial was conducted during 2014-15 in winter season at Horticultural Research Centre, Chauras Campus, H.N.B Garhwal University, Srinagar (Garhwal), Uttarakhand to study the effect of organic manures on growth, yield and quality of radish cv. Pusa Desi. The experiment consisted of 19 treatments with control, laid out in Randomized Block Design with three replications. The quantitative parameters were recorded at 15 days interval.The maximum plant height (36.13 cm) number of leaves (16.88) at 60 days, leaf length (17.17 cm), total plant height (58.68 cm) and root length (20.04 cm) were recorded with the combined application of organic manures (Vermicompost 50% + Poultry manure 50%). Whereas, the total plant weight (305.04 g), fresh weight of leaves (134.77 g), root weight (197.07 g), root diameter (5.74 cm) and yield/ha (36.42 t/ha) were significantly maximum with with the combined use of (FYM 100% + Vermicompost 100% + Poultry manure 100%). The quality parameters like T.S.S (6.15 B) and Vit.C (18.13 mg/ 100g) were recorded maximum in combined application of FYM 50% + Poultry manure 50% and acidity (0.64) was maximum due to the FYM 100%. The study suggested that the combined application of Vermicompost 50% + Poultry manure 50% or (F.Y.M + Vermicompost + Poultry manure) were highly beneficial for all of the growth, yield and quality parameters.

The sixteen treatments were compared in randomized block design (RBD) with three replications. The seed was sown at spacing of 45 cm x 15 cm on ridges. The seed-pods were picked before shattering through successive pickings as and when required. The studies were concentrated on crop-stand, plant-growth and development traits, crop productivity, seed quality and net profit (`) per hectare. It is inferred from the findings that the seed crop of okra cv. Parbhani Kranti during the spring-summer (Zaid) season should be cultivated in western Uttar Pradesh by applying nitrogen @ 100 kg ha1, phosphorus @ 40 kg ha1 and Azotobacter @ 2 kg ha1.

Effect of fertilizers and micronutrients on hoppers showed that the treatment 1.5 kg N + 1 kg P2 O5 and 1 kg K O 2 along with Cu, Zn, B and S applied was most effective in checking multiplication of hopper population, whereas the treatment with 2 kg N only was least effective as maximum hopper population (20.06 hopper per panicle in 3rd observation) was recorded here. However, in rest of the treatments, hopper population was more or less equal to control. Maximum fruit set (189.75 and 139.25 fruits per 100 panicles) was observed in the treatment where 1.5 kg N, 1.0 kg P2O5 and 1 K2O were used along with Cu, Zn, B and S that was significantly different from control followed by the fruit set in recommended dosage. Minimum fruit set (116.00 and 105.25 per 100 panicles) was recorded in control. Fruit harvested and fruit weight were again highest (110.25 and 21 kg per 100 panicles) where 1.5 kg N, 1.0 kg P2 O5 and 1 kg K2O were used along with Cu, Zn, B and S followed by fruit yield in recommended dosage. Lowest fruit number and fruit weight (100.25 and 16.30 kg per 100 panicles) were observed in treatment where only 2.0 kg N was used

Effect of different number of irrigations on hoppers showed that maximum hopper populations were recorded in nine irrigations where one irrigation each in October, December and February and two irrigations each from April to June were given, whereas hopper population were at par in five irrigations where two irrigations each in April and May and one irrigation in June were given, in two irrigations where one irrigation each in April and May were given and in control where no irrigation was done. The fruit set was significantly different in all treatments as compared to control whereas maximum fruit set (190.42 and 126.42 fruits/panicles) was recorded in five irrigations. Fruits harvested were maximum (108.57 fruits/100 panicles) in five irrigations that were significantly different from control. Weight of fruits per 100 panicles was maximum (18.80 kg) in five irrigations, which were at par with the two irrigations, and nine irrigations, however all these were significantly different from the control where minimum (16.38 kg/100 panicles) fruit weight was recorded.

Western Himalaya is a reservoir of plants that constitutes a large number of economically important species of both pharmaceutical and medicinal importance. Many of these plant species have become rare and endangered and are in the verge of extinction due to over exploitation. One of such plant is Picrorhiza kurroa which is high altitude plant with a large number of therapeutic properties. Therefore, it is extremely important to explore the different methods of propagation and conservation of P. kurroa under in vitro conditions and also in its natural habitat.
