Ipomoea carnea subsp. fistulosa (bush morning glory) is a alien invasive weed species, native of Latin America, spread throughout the fresh water ecosystems of tropic and sub – tropics . I. carnea subsp. fistulosa infestation generally found in undisturbed areas, through release of allelochemical monopolise the natural resource, thus replace the original native species , . Water from fresh water tanks and pond obviously feed to rice crop. Allelopathic effect of I. carnea subsp. fistulosa is not reported on any crop plants. This is the novel work which examine the allelopathic effect of I. carnea subsp. fistulosa aqueous leaf extract on rice. The leaf samples for aqueous extract collected from near by infestation. Here, aqueous leaf extract treatments namely 5, 10, 15, 20 per cent and control (distilled water) employed. Two sets of germination experiments were conducted viz., petri dish method and roll towel method with 25 seeds each. Periodic observations clearly indicates the potential inhibition of leaf aqueous extract of I. carnea subsp. fistulosa on rice crop germination.
The present study sought to determine the effectiveness of growth, yield and quality of strawberries in different container sizes and growing media. The experiment was carried out at Research Farm, Division of Fruit Science, Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main campus, Chatha, during the year 2020-21. Three replicates of each plant were tested using containers of six different sizes, i.e., (24 cm × 24 cm × 14 cm), (25 cm × 21 cm × 12 cm), (20 cm × 20 cm ×10 cm), (37 cm × 23 cm × 9 cm), (35 cm × 18 cm × 14 cm) and (23 cm × 23 cm × 10 cm) in factorial randomized block design. The strawberry plants were planted in containers filled with a growing media of cocopeat, perlite and vermicompost in the following ratios: 1:1:1, 2:1:1, 3:1:1, 4:0:1, 4:1:0, 4:1:1, respectively, and control. At the end of the study, observations on the growth, shoot, leaf, flower, root and biochemical parameters of each plant were recorded. Among all the treatments, the results showed plants raised in PVC pots with a growing media ratio of 3:1:1 (C2T3) had significantly greater height, higher growth, maximum flowering and fruiting. Also, the cost and returns were reported to be higher in polyethylene bags with a growing media ratio of 3:1:1 (C1T3) with a benefit cost ratio of 1:1.70. Thus, it is recommended that for strawberry production in open areas, PVC pots with growing media in a 3:1:1 ratio be used, as this will ensure greater success in plant establishment and provide disease-free, healthy strawberries. It is also indicated that soilless production of containerized strawberries cv. Chandler can be taken as commercial cultivation.
The current investigation aims to study the effects of different IBA concentrations and growing media on karonda cuttings at Research Farm, Faculty of Agriculture, Division of Fruit Science at Sher-e-Kashmir University of Agricultural Sciences and Technology of Jammu, Main Campus, Chatha during the year 2018-19. The treatments consisted combination of three levels of IBA (7000, 8000 and 9000 ppm) with three different concentrations of sucrose (3, 4 and 5% respectively) and also contains the three different types of rooting media viz., soil, sand, FYM (1:1:1), vermiculite (100%) and cocopeat (100 %) which was laid out in a factorial completely randomized design with three replications. The results obtained from the study exhibited that the shortest time to first sprouting i.e. 9.5 DAP, maximum sprouted cuttings i.e. 16.00, the maximum percentage of cuttings that sprouted i.e. 80 percent the longest shoot (8.46 cm), maximum number of shoots per cutting (6.15), longest diameter of shoot (8.31 mm), maximum shoot fresh weight (2.21 g), maximum shoot dry weight (1.16 g), highest leaf number per cutting (16.80), total leaf area (4.26 cm2), maximum leaf fresh weight (0.27 g), maximum leaf dry weight (0.14 g) and maximum leaf chlorophyll content (SPAD value of 75.20) were recorded with combination of 8000 ppm IBA, 4 percent sucrose and vermiculite media. Furthermore, the total number of roots per cutting (13.12), longest root length (8.46 cm), mean root length (11.30 mm), root fresh weight (0.53 g), root dry weight (0.29 g) and survival percentage (43.33) were also found to be highest with 8000 ppm IBA, 4 percent sucrose and vermiculite media. From this study, it is concluded that the combined effect of 8000 ppm IBA, 4 percent sucrose and vermiculite had a great impact on the successful propagation of karonda by cuttings, as it yielded best results in terms of growth and rooting parameters.
Techno oil and Berna star are two plant extracted products which are used as safe pesticides. Tribolium castaneum (Herbst) and Rhyzopertha dominica (F.) are two major stored product insects. The two tested products were evaluated against R. dominica and T. castaneum adults using two bioassays evaluating their repellency and contact effects. Berna star had stronger repellent activity against T. castaneum. In contrast, Techno oil had the greatest repellency against R. dominica. Furthermore in thin film method Berna star had stronger effect against the two tested insects compared to Techno oil at all exposure periods. After 24 h of exposure the two components had no effect on T. castaneum while after 72 h of exposure the mortality was 100% with all concentrations for R. dominica for two tested components. Using mixing with medium method there was no effect on T. castaneum before 7 days for both tested components, while for R. dominica both tested components had toxicity effect for all used concentrations. For R. dominica after one, three and four days of exposure Techno oil had the stronger effect while for T. castaneum Berna star had stronger effect at all exposure periods. Based on LT50 with the highest concentration (40000 mg/kg) Berna star had stronger effect on both tested insects with LT50 of 6.06 and 1.41 h for T. castaneum and R. dominica respectively. Both tested products achieved 100% reduction against the two tested insects.
The main emphasis was given on the effects of the environmental factors viz: light, temperature, water and gaseous exchange parameters on physiology of litchi production. Environmental stresses can cause morpho-anatomical, physiological and biochemical changes in crops, resulting in a strong profit reduction. The interest has shown on the effect of temperature during panicle emergence, flower development and fruit sun burn and cracking. The stress factors like water stress, cold winter are the triggering factors to induce dormancy which promotes flowering. High temperature and low humidity during fruit growth increases sun burn and fruit cracking. Water stress during fruiting is vulnerable with respect to fruit drop. Understanding environmental factors and their interaction with physiological processes is extremely important for economically sustainable litchi production.
