Morphological Diversity of Fig (Ficus carica L.) Germplasm in the Northwestern Himalayan Region
The fig (Ficus carica L.) is an underutilized fruit tree with significant medicinal and nutritional value. This study presents the morphological characterization of 42 fig genotypes surveyed from the three districts of Jammu and Kashmir, based on quantitative and qualitative traits evaluated through IPGRI and CIHEAM (2003) descriptors to assess diversity and conservation potential. The study revealed substantial morphological diversity among local fig germplasm with tree height ranging from 2.30 to 5.76 m with maximum in genotype SKJFRa (Sel-14) at 5.76 m, trunk girth from 32.83 to 56.47 cm with the largest in SKJFP (Sel-40) at 56.47 cm, and internodal length from 2.35 to 5.13 cm with the longest in SKJFRa (Sel-14) at 5.13 cm. Tree spread in N-S dimensions ranged from 1.76 to 4.34 m, with the maximum in SKJFRa (Sel-17) at 4.34 m and E-W dimensions from 2.41 to 4.87 m, with the maximum in SKJFRa (Sel-10) at 4.87 m. Qualitative analysis revealed conical terminal buds (92.85%) and pyriform fruits (40.85%) as predominant. Most genotypes (71.42%) showed no abnormal fruit formation, and apical dominance was absent in most genotypes (85.71%). Additionally, ostiole size was predominantly medium, present in 47.61% of the studied genotypes. Ward cluster analysis using Euclidean distance classified the genotypes into five major groups. These findings highlight the region's rich fig diversity, underscoring its value for breeding programs and conservation. The study establishes baseline data for sustainable utilization of this ecologically and economically significant species in Himalayan agroecosystems, emphasizing the need for germplasm documentation and targeted cultivation strategies.
Performance of cauliflower genotypes for different horticultural traits in mid hill conditions of Himachal Pradesh
The present experiment was conducted during 2022 and 2023 at the Regional Horticultural Research and Training Station, Bajaura, Kullu, Himachal Pradesh, to evaluate six cauliflower (Brassica oleracea var. botrytis) genotypes—NS-1358, NS-555, NS-2184, Brahma, NS-1114, and NS-2201—for their morphological, curd quality, and yield contributing traits. The study revealed significant variation among genotypes for all traits, while the genotype × year interaction was non significant, indicating consistent performance across seasons. Among the genotypes, NS-2184 recorded the highest plant vigor, curd size (138.62 cm²), curd compactness (37.99 g/cm³), and yield (195.56 q/ha), making it the most promising candidate for commercial cultivation. In contrast, NS 1114 showed the lowest performance across most parameters. The observed genetic variability highlights the potential for selection and genetic improvement. NS-2184 is recommended for cultivation in mid hill regions and as a valuable parent in breeding programs aimed at enhancing curd quality and yield in cauliflower.
Socio-economic & Psychological Profile of Veterinary Medical Officers (VMOs) in Eastern and Western Plain Zone of Uttar Pradesh
The present study was conducted by research scholar of Department of Veterinary & Animal Husbandry Extension Education, ANDUAT, Kumarganj, and Ayodhya in the western & eastern plain zone of Uttar Pradesh. A part from it, the working Veterinary Medical Officers from 6 selected district (Ayodhya, Ambedkar Nagar, Amethi, Meerut, Baghpat, Hapur) of both divisions (Ayodhya, Meerut) was selected thus a total of 54 working VMOs from Meerut division ,55 working VMOs from Ayodhya division was selected. total 109 veterinary medical officers were selected. The quantitative and qualitative data were collected through interview schedule, discussion, observation and available secondary sources. Majority of veterinary medical officers were population of male number 85.32 per cent in eastern and western Plain Zone of Uttar Pradesh. Majority of respondents belonged to middle age group (79.82%). most (48.63 %) of the VMOs were holding B.V.Sc & A.H. courses. 75.23 per cent of respondents belonged to moderate level of rural experience. 77.06 per cent belonged to the medium level (11-16 years) of experience. 57.8 per cent of respondents belonged to medium range salary. 80.73 per cent of the VMOs perceived medium workload. 79.82 % respondents in medium level of facilities and resources. majority (88.07%) of the VMO shad a high accountability to clientele. More than half portion (66.97%) of VMOs showed a medium level of interaction with organizations. 54.13 per cent VMOs belonged to low level of mass media participation. 59.64 per cent of VMOs belonged to low number of publications. 75.23 percent VMOs belonged to medium level of participation in seminars/conferences. 72.48 percent VMOs belonged to medium level of number of training attends. 53.21 per cent of them had medium of subordinates. (9.17%) of the respondents had less livestock population in their jurisdiction. (58.72%) of the respondents had attended less (35-1150) number of cases monthly.
Effect of Ashwagandha on Somatic and Gonadal Development in Cirrhinus mrigala under Sodic Soil Condition
The current investigation was conducted for a period of 90 days to examine the effect of two different doses of Ashwagandha (2% and 3%) on somatic and gonadal development in Cirrhinus mrigala. A total of 270 fish with mean length-weight of 27.49±3.36 cm and 235.5±60.29 gm were stocked randomly into nine earthen trial ponds and distributed as 30 fish in each pond. Whole experiment was of 3 different treatments, T1 (Control), T2 (2% Ashwagandha added diet) and T3 (3% Ashwagandha added diet) and each treatment was designed with 3 replications. During the experiment values of water quality parameters such as pH, Temperature, Dissolve Oxygen and TDS were found within optimal range. Gonadosomatic Index (GSI) for both male and female in April found maximum in T3 and their values were found 2.04±0.1 and 6.73±0.12 respectively (P<0.05). Values of biological indices of male C. mrigala such as regression coefficient “b” (2.44), condition factor (1.08) and SGR (1.08) was found maximum in T2 while in female C. mrigala, regression coefficient "b" (2.1) and SGR (0.256±0.004)was found maximum in treatment T3. In conclusion, 3% Ashwagandha added diet could be a option for obtaining appropriate somatic and gonadal growth of female while in male 2% Ashwagandha supplemented diet could be appropriate for somatic growth and 3% for gonadal growth.
Influence of organic supplements on growth and yield attributes of brinjal (Solanum melongena L.) cv. Pusa Purple Cluster
To assess the response of various organic nutrient sources in brinjal cultivation, an experiment was conducted at the Organic Block of the Research Farm, Department of Vegetable Science, Dr. Yashwant Singh Parmar University of Horticulture and Forestry, Nauni, Solan (HP). The experiment was laid out using a Randomized Block Design with three replications and eight treatments: T1 – absolute control, T2 – farmyard manure (FYM) @ 10 t/ha, T3 – vermicompost (VC) @ 5 t/ha, T4 – FYM @ 5 t/ha + VC @ 2.5 t/ha, T5 – Beejamrit + Jeevamrit, T6 – FYM @ 10 t/ha + Beejamrit + Jeevamrit, T7 – VC @ 5 t/ha + Beejamrit + Jeevamrit, and T8 – FYM @ 5 t/ha + VC @ 2.5 t/ha + Beejamrit + Jeevamrit. Among the different organic treatments, T7 outperformed others in most of the yield and yield-contributing traits and also showed the lowest incidence of insect pests and diseases. The maximum fruit breadth, fruit weight, and marketable fruit yield were recorded under T7. However, in terms of quality parameters, T8 recorded the highest ascorbic acid content and total soluble solids (TSS), which were statistically at par with T7. Therefore, the application of vermicompost @ 5 t/ha along with Beejamrit (as seed treatment) and Jeevamrit (as soil drench and foliar spray @ 5%) can be recommended for improved growth, higher yield, reduced pest and disease incidence, and sustainable crop production under changing climatic conditions.
