During the last era in India, the use of chemical fertilizer has increased tremendously. The excessive use of these chemicals leads to the degradation of soil quality, health, as well as nutritional status. These are also causing a degradation of human health. This experiment was conducted during Mrig Bahar (July to December) during two consecutive years (2019–2020)in a randomized block design with three replications in which six-year-old 42 pomegranate plants were tested with 14 treatments of different organic manures. Findings showed that in the various treatments, the organic combination T13-Jeevamrut 16.08 L plant-1 + Vermicompost 24.79 kg plant-1 had a significant effect on the nutritional status (available nitrogen, available phosphorus, and available potassium) and microbial population (fungi, bacterial, and actinomycetes count). In addition, T13-Jeevamrut 16.08 L plant-1 + Vermicompost 24.79 kg plant-1 found a significant effect on fruit yield characteristics like fruit plant-1 (122.00), fruit yield (17.38 kg plant-1), fruit weight (192.50 g) and fruit quality characteristics such as fruit juice percent (52.92%), and total sugar (11.92%).
:The experiment consisted of 12 treatments combinations comprising 4 nitrogen levels (60, 80, 100 and 120kg ha -1 ) and 3 zinc levels (2.5, 5.0 and 7.5kg ha -1 ). The experiment was laid out in Factorial Randomized Block Design with four replications. The experimental soil was clay loam in texture, slightly alkaline in reaction, medium in available nitrogen (275.0 kg ha -1 ) and phosphorus (20.21kg ha -1 ) and potassium (280.5kg ha -1 ) and low in available zinc (0.49ppm). The crop was shown on 9.7.2011 using variety PEHM-2 with recommended seed rate of 25kg ha -1 . The results revealed that application of N upto 100kg ha -1 recorded significantly higher plant height (50, 75DAS and at harvest), dry matter accumulation and leaf area index at all the growth stages over 60 and 80kg N ha -1 . Likewise, application of N upto 100kg ha -1 was found significantly superior in increasing RGR and NAR between 25 and 50 days compared to 60kg N ha -1 . Application of 100 and 120kg N ha -1 statistically at par were found significantly superior in increasing cob plant -1 , grain cob -1 , grain weight cob -1 , 100 grains weight and shelling per cent over 60 and 80kg N ha -1 . Application of 80 and 100kg N ha -1 significantly increased grain; stover, biological yield and harvest index over 60kg N ha -1 . The per cent increase in grain, stover and biological yields due to 100kg N ha -1 was 39.03, 23.43 and 28.89, respectively compared to 60kg N ha -1 . A significant increase in N, P and Zn content and their uptake was recorded under the application of 80, 100 and 120kg N ha -1 compared to 60kg N ha -1 but 120kg N ha -1 was found statistically at par with 100kg N ha -1 . Protein content in grain and chlorophyll in leaves increased significantly with successive increase in nitrogen doses upto 100kg ha -1 .

:The experiment was laid out in a Factorial Randomized Block Design with twelve treatments and replicated thrice. Results indicate that the seed inoculation with Rhizobium showed some good results increasing numbers of nodules and uptake of nutrients due to inoculation. Significant effects were observed in plants growth attributes due to presence of phosphorus and uptake of phosphorus increased due to presence of sulphur @ 20kg ha -1 ultimately resulting in good yield. However, plant heights (66.00cm), Number of branches plant -1 (4.82), Number of nodules plant -1 (5.83), Number of grains pod -1 (12.56), test weight (51.03g) and grain yield (12.39 q/ha) were found significantly affected by the application of Rhizobium inoculation, application of 45kg phosphorus through DAP and 20kg sulphur through Gypsum ha -1 . Cost benefit ratio was also found (2.22) on higher side.
The importance of fennel is well realized on account of its high remunerative prices, domestic consumption, medicinal value and means to get earn foreign exchange. Despite the economic importance of fennel, disease resistant, locally acceptable and high yielding crop. The present investigation was therefore, carried out to estimate the magnitude and nature of genetic variability in terms of variation, heritability, genetic advance and genetic diversity for different traits like seed yield per plant and yield contributing traits in a set of 50 germplasm with four checks and extent of environmental influence on these traits, form the basis on which a breeder can predict the extent of dependence on phenotypic selection for improvement of traits. The analysis of variance revealed that significant amount of variability was present in germplasm lines for almost all morphological traits studied as days to germination, 50 per cent flowering, king umbel anthesis, number of number of primary branches, number of secondary branches, plant height (cm), diameter of king umbel (cm), number of umbels per plant, number of umbellates per umbel, number of seeds per umbel, at a test-weight (g) and seed yield (g). A wide range of mean for yield and some of its contributing traits indicates good chance for improvement of yield through direct selection or by transferring desired traits. , were found to be superior. The variability of characters was compared on the basis of co-efficient of variation. The genotypic co-efficient of variation (GCV) and phenotypic co-efficient of variation (PCV) were worked out. Higher GCV (genotypic co-efficient of variation) was recorded for number of umbels per plant (15.7), seed yield (12.4) and number of secondary branches per plant (12.3), it expresses the true genetic potential which indicated the presence of high amount of genetic variability for these characters thus, selection may be more effective for these characters because the response to selection is directly proportional to the component of variability, while, number of seeds per umbellate (11.9), king umbel diameter (10.8) and umbellate per umbel showed moderate to high genotypic co-efficient of variation. Whereas primary branches (9.6), test weight (8.1) showed low magnitude of genotypic co-efficient of variation. Higher PCV was recorded for number of umbels per plant (16.7), king umbel diameter (14.3) and number of secondary branches per plant (14.0), while, seed yield (g) (12.5), number of seeds per umbellate (12.1) and number of umbellates per umbel (11.1) showed moderate to high phenotypic co-efficient of variation. Whereas number of primary branches (10.6), test weight (g) (8.9) showed low magnitude of phenotypic co-efficient of variation.
An experiment was carried out during at Horticulture Farm, Rajasthan College of Agriculture, Udaipur, Rajasthan during 2018 (February to May) to work out the most suitable growing media and Indole-3 Butyric Acid concentration for producing the best quality cutting of Pomegranate. The experiment was laid out in a completely randomized design with a total of sixteen treatments replicated thrice. Result showed that the treatment combination (T13) comprising Coco peat : Perlite : Vermiculite with 2000 ppm IBA recorded highest values in terms of length of cutting after survival (81.08 cm), percentage of rooted cuttings (97.78%), survival of rooted cuttings (93.78%), number of roots per cutting (41.50), length of longest roots per cutting (32.03 cm), fresh weight of root (2.25 g), sprouts per cutting (2.59), shoots per cutting (9.87), length of shoots per cutting (32.33 cm), leaves per rooted cuttings (145.40), leaves per longest shoot (29.99), fresh weight of shoot (16.67 g), root to shoot ratio (0.15) and survival percentage after shifting in poly bags (82.22).
