The experiment was conducted in the Ecology Field, Arid Forest Research Institute, Jodhpur (Rajasthan), India during 2020-21 to explore the role of insect pollinators in the fruit setting of P. cineraria. For conducting the experiments one of the branches of the selected trees was covered with a mesh bags to exclude floral visitors (pollinator exclusion). The other branch was kept uncovered for the time of the experiment (open pollination). Our findings revealed that the average fruit set under pollinator exclusion (bagged condition) was nil whereas it was 2.02% in open natural pollination. This study confirms previous studies that P. cineraria is a cross–pollinated species. Also, average moisture content was found to be 10.75 % in seeds and 49.21% average carbohydrate content in pods under open pollination, germination percentage was found to be 71.3% and seedling vigour index was 655.2. Present study also calculated the average seed weight, average seed length, average seed breadth, average seed thickness obtained in above experiment.

The present investigation was carried out during 2017 at the Department of Plant Pathology, Dr YS Parmar University of Horticulture and Forestry, Nauni, Solan. The objective of the study was to understand the prevalence of bacterial wilt of tomato as influenced by the edaphic factors. Periodic survey were undertaken during the crop season in major tomato growing regions and incidence of bacterial wilt of tomato ranged from 10.00% to 84.02%. 20 days old tomato seedlings were inoculated with bacterial suspension (3x108 cfu/ml) either through root dip or drenching and kept in green house with temperature 30+2°C. Inoculation of bacterial pathogen R. solanacearum in through seedling root dip in bacterial suspension was found better compared to drench application for development of typical symptoms of bacterial wilt disease. There was 100% disease incidence with seedling root dip method compared to 68.74% disease incidence with drenching of bacterial suspension in soil. Epidemiological studies of R. solanacearum revealed that with the increase in soil moisture from 40% to 90%and soil temperature from 25° to 35°, there was a progressive increase in disease incidence of bacterial wilt in tomato seedlings. Maximum disease incidence was observed at 30–35°C and at 90% soil moisture. However, no disease was observed at 20°C and at 20% and 30% soil moisture. The finding on epidemiology from the present study will be helpful to design effective disease management strategy.

The present investigation was carried out at Experimental Farm of Regional Horticultural Research and Training Station Dhaulakuan, District Sirmour (HP), Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan, Himachal Pradesh, during Kharif season, 2018 to ascertain extent of variability, heritability and genetic advance as percentage of mean for yield and other horticultural traits of 21 chilli genotypes. The experiment was laid out in RCBD with three replications at spacing of 45cm × 45cm. Analysis of variance indicated significant differences among the genotypes for all the traits studied. RACH-132 exhibited the maximum number of fruits per plant (97.27), fruit weight at edible maturity (4.08 g), green fruit yield plant-1 (280.10 g), red fruit yield plant-1 (275.89 g) and fruit diameter (1.23 cm) while, number of seeds and thousand seed weight was maximum in RACH-121 (100.40, 5.12 g). DKC-8 (0.49%) recorded the maximum capsaicin content. The estimates of phenotypic and genotypic coefficients of variation (PCV and GCV) were moderate to high for all characters studied except days to first red maturity. High heritability coupled with high genetic gain was found for characters like green fruit yield plant-1, red fruit yield plant-1 and capsaicin content which indicates that these characters were under the strong influence of additive gene action and hence simple selection based on phenotypic performance of these traits would be effective.

Andrographis paniculata is an important medicinal plant which possesses many medicinal applications. Looking to the importance of plant growth regulators one study was carried out on the influence of foliar spraying treatments in the yield of Kariyatu. Different treatments which includes NAA (50,100 and 200 mg l-1) , GA3 (50,100 and 200 mg l-1) and Paclobutrazol (50,100 and 200 mg l-1) with one as control were considered as foliar application at 30 days after transplanting. Experimental results indicated leaf, shoot and total dry matter increased in all the treatments progressivelly upto harvest but root-shoot ratio decreased with increase crop growth stage that means high proportion of shoot is increases. Leaf area duration was increased progressively up to 75–105 days after transplanting and thereafter declined while crop growth rate was shown increased up to 45–75 days after transplanting then decreased during the 75–105 days after transplanting which means after reproductive stage to maturity phase of growth, crop growth rate decline. The biomass duration was increased with age of the crop till harvest. Significantly positive effect was reported in GA3100 mg l-1 and lowest result was found in control. The translocation process must have been more prominent in the foliar spraying of GA3 100 mg l-1 than rest of the treatments indicates that photosynthesis and translocation efficiency increases by foliar spraying treatments with growth regulators. GA3 100 mg l-1 is efficient in dry matter production and its partitioning in leaves, stem as compared to other treatments.

Practicing wheat-maize cropping system by the farmers of Himachal Pradesh is less economical viable as compared to pulses. Besides this, pulses have high potential of soil improvement through nitrogen fixation. Hence, the experiment was premeditated to evaluate the carbon stock potential and economic profitability of cereals and pulses under Harar and Aonla based agroforestry systems in the low hill zone of Himachal Pradesh. The experiment was conducted with nine treatment combinations with four replications in RBD. Highest biomass (77.80 t ha-1) and carbon stock (38.05 t ha-1) were recorded under maize+Harar. In term of economics, maximum gross returns (80,471.49 ` ha-1) were obtained for maize+Aonla yet, the maximum net returns (42,684.40 ` ha-1) and BC ratio (2.14) were found for mash+Aonla.

Markers are any trait of an organism that can be identified with confidence and relative ease, and can be followed in a mapping population or they can be defined as heritable entities associated with the economically important trait under the control of polygenes. Molecular markers have diverse applications in fruit crop improvement, particularly in the areas of genetic diversity and varietal identification studies, disease diagnostics, hybrid detection, sex differentiation and marker assisted selection. Molecular markers provide new directions to the efforts of plant breeders particularly in gene localization, taxonomy, phylogenetic analysis and also play an important role to decrease the time required for development of new and excellent cultivars. The most interesting application of molecular markers is marker-assisted selection (MAS). Suitable DNA markers should be polymorphic in the nature and should be expressed in all tissues, organs, at various developmental stages. Compared with traditional breeding programs, molecular markers can increase the efficiency and effectiveness of fruit breeding programs.

Groundnut (Arachishypogaea) is an oilseed crop grown in West Bengal, India. These nuts are used as oil crops and grain legume crops. Most of the farmers cultivate the traditional and age-old varieties. As a result, the production and productivity are relatively low when compared with that of the recently cultivated varieties. In West Bengal conditions, TG51 and TAG24 varieties are found suitable for small farmers. The present study was carried out in Purulia district of West Bengal. Total twenty-five (25)demonstrations was carried out in the farmers’ field as per the guidelines of All India Coordinated Research Project (ICAR-AICRP). The demonstrations were carried out duringthe 4 months of kharif season (July-October) in the year 2019. The collected data was tabulated and analyzed on the basis of range, mean and percentage Gaps at different percentage have been observed in different management practices like seed rate, seed treatment, fertilizer management and insecticide application.Farmers were motivated to follow new seed varieties and improved management practices.In demonstration fields, gross return increased by 48.80% and net return increased by 53.79% over the farmers’ fields. There was a 7.24% increase in benefit cost ratio. It is necessary to motivate farmers to adopt new technologies for future cultivation and this, in turn, would help to develop the socio- economic status of the farmers of this area.

Historically, root diseases have been a production-limiting problem for the strawberry industry worldwide. Even though this disease is of great economic importance, the etiology remains unresolved. However, soilborne fungal root pathogens, particularly Pythium and Rhizoctonia spp. have been implicated as major role players. Presence of nematodes in soil and favourable environmental conditions also play significant role in the disease development. Development of integrated disease management strategies is dependent upon a more complete understanding of the etiology, biology and ecology of the disease complex.
