Chaudhary Sarwan Kumar Himachal Pradesh Agriculture University, Palampur

Himachal Pradesh Krishi Vishvavidyalaya (renamed as Chaudhary Sarwan Kumar Himachal Pradesh Krishi Vishvavidyalaya in June, 2001) was established on 1st November, 1978.The College of Agriculture (established in May, 1966) formed the nucleus of the new farm University. It is ICAR accredited and ISO 9001:2015 certified institution. The Indian Council of Agricultural Research has ranked this University at eleventh place among all farm universities of the country. The University has been given the mandate for making provision for imparting education in agriculture and other allied branches of learning, furthering the advancement of learning and prosecution of research and undertaking extension of such sciences, especially to the rural people of Himachal Pradesh. Over the years, this University has contributed significantly in transforming the farm scenario of Himachal Pradesh. It has developed human resources, varieties and technologies and transferred these to farming community enabling the State to receive the “Krishikarman award” of Govt. of India four times in row for food grain production among small states of the country. Today, the State has earned its name for hill agricultural diversification and the farming community has imposed its faith in the University.

    EFFECT OF ROOTSTOCKS AND GRAFTING TECHNIQUES ON HORTICULTURAL TRAITS AND GUMMY STEM BLIGHT IN PARTHENOCARPIC CUCUMBER
    (CSKHPKV, Palampur, 2019-04-24) Anjali; Pardeep Kumar
    Grafting has a potential for higher yield and disease control in the cultivation of cucurbitaceous crops. Considering this aspect the field experiment entitled “Effect of rootstocks and grafting techniques on horticultural traits and gummy stem blight in parthenocarpic cucumber” was undertaken at the Vegetable Research Farm, Department of Vegetable Science and Floriculture, CSK HPKV, Palampur Himachal Pradesh with two objectives- in vitro screening of different rootstocks for gummy stem blight, and to study the effect of rootstocks and grafting techniques on yield and quality attributes in cucumber. The seeds of local varieties of different rootstocks ie. Summer squash, bottle gourd, pumpkin, ash gourd, luffa, cucumber and bitter gourd were procured from the local farmers. The seven cucurbit rootstocks were screened in vitro against the disease gummy stem blight by inoculating fungus Didymella bryoniae. All the rootstocks screened showed resistance to the fungal pathogen Didymella bryoniae. The experiment was laid out in a Randomized Block Design with three replications and data were recorded on various horticultural and quality traits of grafted plants viz. Days to first flowering, Days to first fruit set, Days to first harvest, Number of marketable fruits per plant, Marketable fruit yield per plant (kg), Average fruit weight (g), Marketable fruit yield per square meter (kg/m2), Fruit length (cm), Fruit diameter (cm), Harvest duration (days), Vine length (cm), Internodal length (cm), TSS (ºBrix), Shelf life and Grafting success per cent (%) . Most of the characters under investigation were significantly influenced by the interaction effect of rootstocks and grafting techniques. Treatment RS5GT3 (RS5= Bitter gourd, GT3= Splice grafting) resulted in minimum number of days to first flower (16.17 days), days to first fruit set (24 days) and minimum number of days to first fruit harvest (32.89 days). Treatment RS2GT3 (RS2= Bottle gourd, GT3= Splice grafting) resulted in the highest grafting success per cent (96.67%), maximum number of marketable fruits per plant (16.35), maximum marketable fruit yield per plant (2.53 kg), maximum marketable fruit yield per square meter (12.66 kg/m2) and maximum vine length (350 cm). Treatment RS1GT3 (RS1= Summer squash, GT3= Splice grafting) resulted in the highest average fruit weight (160.06 g) and fruit length (17.25 cm). Minimum internodal length (9.83 cm) was observed in treatment RS6GT2 (RS6= Luffa, GT2= Hole insertion grafting) and highest TSS of (3.60°Brix) was observed in treatment RS4GT2 (RS4= Cucumber, GT2= Hole insertion grafting). The interaction effect of rootstocks and grafting techniques had no significant effect on fruit diameter and harvest duration. Therefore, it is inferred from the study that bottle gourd is best compatible rootstock along with splice grafting technique for securing high yield in parthenocarpic cucumber as well as for resistance against gummy stem blight under protected conditions.

    STUDIES ON THE DISTRIBUTION OF ZINC FORMS IN SOME CULTIVATED SOILS OF OUTER HIMALAYAS
    (CSKHPKV, Palampur, 2017-07) Anjali; Sharma, V.K.
    Understanding the spatial distribution of various forms of zinc (Zn) in soils helps in predicting its short- and long-term availability for sustainable crop production. In the present investigation, 101 surface soil samples, representing major soils (Entisols & Inceptisols) and land use types of cultivated lands in Outer Himalayas of Himachal Pradesh, were collected to study the spatial distribution of Zn forms and their relationship with important soil properties. The soil samples were collected at 0-15 cm depth from cultivated soils under maize-wheat, paddy-wheat, vegetable-based & sugarcane-based cropping sequences and at 0-30 cm depth from orchards of mango, mandarin, guava and litchi and analyzed for important soil properties and Zn forms using standard methods. Sand (%), silt (%), clay (%), textural class, soil pH (1:2.5), electrical conductivity (dS m-1 ), organic carbon (%), cation exchange capacity {cmol(p+) kg-1}, base saturation (%) and calcium carbonate (%) in cultivated soils of Outer Himalayas ranged from 40 to 80, 12 to 45, 6 to 24, loamy sand to sandy clay loam, 6.1 to 7.8 (slightly acid to slightly alkaline), 0.142 to 0.372, 0.305 to 1.525, 4.7 to 13.3, 60 to 77 and 0.05 to 2.20, respectively. Available N, P, K, Ca, Mg, S, Cu, Fe, Mn and Zn in the soils studied were low to medium, low to medium, medium, medium to high, medium to high, low to medium, sufficient, sufficient, sufficient and deficient to sufficient, respectively. Per cent soil samples deficient in N, P, S and Zn were 26, 47, 59 and 39, respectively. Such a spatial variation may be explained in light of pedo-genesis and prevailing nutrient management practices. Water soluble, exchangeable, specifically adsorbed, organically bound, Mn-oxide bound, Al- and Fe-oxide bound, residual and total Zn in soils under different land use types varied from 0.057 to 0.365, 0.171 to 0.575, 0.33 to 3.07, 3.40 to 17.97, 1.30 to 10.82, 4.76 to 32.75, 14.78 to 79.50 and 30.44 to 130.65 mg kg-1 with mean values of 0.167, 0.366, 1.57, 9.31, 5.40, 17.77, 52.96 and 87.53 mg kg-1 , respectively. On an average, water soluble, exchangeable, specifically adsorbed, organically bound, Mn-oxide bound, Al- and Fe-oxide bound and residual Zn constituted about 0.20, 0.45, 1.77, 10.61, 6.02, 19.94 and 61.01 per cent of total Zn, respectively. There were significant and positive correlations between different chemical pools of Zn, indicating the existence of dynamic equilibrium among them. Clay, organic carbon and cation exchange capacity were significantly and positively correlated with each form of Zn; while sand, pH and calcium carbonate were negatively correlated. Silt was significantly and positively correlated while electrical conductivity and base saturation were negatively correlated with most of Zn forms. Such interrelationships indicated that basic soil attributes studied are important factors affecting the distribution of Zn forms in the study area. Among all, per cent clay, organic carbon and cation exchange capacity exhibited better correlations with each form of Zn. Further, soils with lower values of clay, organic carbon and cation exchange capacity contained less amount of soil Zn in each pool as compared to soils higher in those soil arributes. Therefore, former soils require relatively more attention on Zn fertilization as compared to latter ones for sustaining soil productivity.
