ThesisItem Open Access NUTRITIONAL STATUS OF VEGETABLE GROWING AREAS OF MANDI DISTRICT OF HIMACHAL PRADESH(COLLEGE OF HORTICULTURE AND FORESTRY, DR Y S P UHF, NERI, HAMIRPUR, 12-02-20) THAKUR, NISHANT; SHARMA, RAKESHThe present study was undertaken to evaluate nutritional status of vegetable growing areas of Mandi district. Soil and leaf samples were collected from 49 pea growing villages of Gohar and Sundernagar blocks of Mandi district. The collected soil and leaf samples were analyzed for different soil properties such as soil texture, bulk density, pH, electrical conductivity, soil organic carbon and available N, P, K, Ca, Mg, S, Fe, Mn, Cu and Zn nutrient. The leaf samples were analyzed for nutrient such as N, P, K, Ca, Mg, S, Fe, Mn, Cu and Zn. On the basis of soil textural classes, the soils of different pea growing areas varied from silty loam to clay loam and the bulk density is < 1.6 g cm-3, hence the soils are less compact and do not interfere with root growth. The soils were acidic to neutral in soil reaction. The soils are in safe limits of electrical conductivity as the values were less than 0.8 dS m-1. Soil organic carbon status was found to be medium to high in both layers. The available N content was low in surface and sub-surface layers. The available K, Cu and Zn contents were medium to high in availability, whereas P, Ca, Mg, S, Fe and Mn were high in status. The leaf nutrient status indicated that 42.96, 71.85, 11.11 and 11.11 per cent samples were deficient in N, P, S and Cu, while 89.63, 92.59, 87.41 and 88.89 per cent were sufficient in K, Ca, Mg and Cu. However, nutrient status of leaf Fe, Mn and Zn were high in 100, 66.67 and 65.93 per cent samples. Soil organic carbon was significant and positively correlated with N, Fe, Mn and Zn. Available Ca and Mg exhibited significant and positive relationship with their respective leaf nutrient contents. On the basis of coefficient of variation, the soil properties such as the bulk density, pH and exchangeable Ca are least variable. Whereas, available nutrients like N, Ca, Mg, Fe, Mn and leaf N, P, K, Ca, Mg, S and Cu are moderately variable. However, electrical conductivity, OC, available P, K, S, Cu, Zn and leaf Fe, Mn and Zn are highly variable. For moderately and highly variable soil parameters, site specific nutrient management strategies should be developed and popularized for enhancing the productivity of the crop in the region.ThesisItem Open Access STUDIES ON EFFECT OF INTERCROPPING AND MANURIAL PRACTICES ON YIELD AND QUALITY OF BRINJAL (Solanum melongena L.)(UHF,NAUNI, 2022-11) THAKUR, NISHANT; SHARMA, H DEVABSTRACT The present investigation entitled “Studies on effect of intercropping and manurial practices on and quality of brinjal (Solanum melongena L.)” was carried out at Experimental Farm and Quality Analysis Laboratory, Department of Vegetable Science, Dr Yashwant Singh Parmar University of Horticulture and Forestry, (Nauni) Solan (HP) during Kharif 2021. The experiment was conducted on main crop brinjal var. Pusa Purple Long and intercrops maize var. Local Selection and okra var. P-8 which was laid out in Randomized Complete Block Design with three replications, comprising of seven treatments viz. T1: Brinjal intercropped with Maize + FYM, T2: Brinjal intercropped with Maize + FYM + Beejamrit + Ghanjeevamrit + Jeevamrit, T3: Brinjal intercropped with Maize + FYM + RDF, T4: Brinjal intercropped with Okra + FYM, T5: Brinjal intercropped with Okra + FYM + Beejamrit + Ghanjeevamrit + Jeevamrit, T6: Brinjal intercropped with Okra + FYM + RDF and T7 (Control): Brinjal sole crop + FYM + RDF. Analysis of variance showed significant variations for effect of intercropping and manurial practices on most of the parameters studied. Among different treatments, sole brinjal + FYM + RDF (T7) recorded maximum number of fruits per plant (10.15), fruit length (22.43 cm), fruit breadth (3.09 cm), fruit weight (100.84 g), fruit volume (104.66 cc), numbers of leaves per plant (149.00), plant spread (70.71 cm), plant height (72.99 cm), number of branches per plant (4.60), stem girth (5.47 cm), yield of brinjal per plant (1065.67 g) and projected per hectare (276.24 q) which were statistically at par with brinjal intercropped with okra + FYM + RDF (T6). The treatment T6 performed best in yield of intercrops [per plant (322.07 g) & projected per hectare (41.75 q)] and total brinjal and brinjal equivalent yield [per plant (1375.40 g) & projected per hectare (314.75 q)] which was statistically at par with brinjal intercropped with okra + Beejamrit + Ghanjeevamrit + Jeevamrit (T5) which also recorded maximum TSS (6.97 oB), fruit flesh density (0.99 g/cc), ascorbic acid content (15.46 mg/100g) and minimum days to 50% flowering (44.67), fruit borer infestation (10.05%), shoot borer infestation (8.96 %) and fruit borer incidence (9.36%). From the present investigation, it can be concluded that brinjal cv. Pusa Purple Long intercropped with okra and application of recommended doses of manures and fertilizers (100 q/ha FYM + 50 kg N/ha + 60 kg P2O5/ha + 45 kg K2O/ha) gave the highest yield of brinjal (273.00 q/ha) and okra (41.75 q/ha) along with maximum net returns per hectare (` 3,99,955) and B:C ratio (1.74) followed by brinjal intercropped with okra + 100 q/ha FYM + Beejamrit + Ghanjeevamrit + Jeevamrit gave yield of brinjal 245.69 q/ha and okra 41.48 q/ha along with net returns per hectare ` 3,49,505 and B:C ratio 1.55 under mid hill conditions of Himachal Pr
