The cluster demonstration of dragon fruit at Muthi & Durtlang Village of Aizawl District has demonstrated under PKVY Programme in the year 2019. A total of 30 farmers were demonstrated for that KVK has provided altogether 1000 nos. of cutting from 2-3 years old strong and dark green healthy (damage free & pest free) and 300 nos. RCC pole 100 mm concrete post with the height of 2 m of selected beneficiaries. Each plant was fed 15-20 kg with organic inputs well decomposed FYM or poultry manure, coir compost and vermicompost along with bio-fertilizers and recommended dose of fertilizer: (500: 300:250 NPK and 100 each of Azotobacter, Phosphate Solubilizing and Potash Solubilizing Bacteria were applied to each plant g/plant/year.) Applied in three doses just before flowering (in April), fruit developing stage (July -August) and after harvesting time (in December).The results revealed that there were significant differences in term of vine length (196.26cm), vine thickness (19.03cm), number of vines per plant (5.98) over the farmers practices which was vine length (182.23cm), vine thickness (17.95cm), number of vines per plant (5.14) The results revealed that there were significant differences over farmer practices as influenced by technology demonstration treatment in both the demonstration year. The demonstrated technologies recorded average yield of 8.043 tone/ha which was 18.50 percent higher than the obtained with farmer’s practices of 6.787 tone/ha. The demonstrated field gave higher mean gross return (`USD 12763.70 /ha) and mean net returns (`USD 12155.91 /ha) with average benefit cost ratio of 1.14 compared to benefit cost ratio of 1.04 over farmer practices. The findings demonstrated that by implementing suggested technology, broccoli yield and economics can be improved.

In the present study NRCS model is applied with a velocity factor estimation technique that relies on length and slope characteristics of a watershed. As given by Kirpich formula and velocity relationship characteristics flow velocity for a watershed can be estimated directly by using length and slope values. The model is applied to derive 1-hr UH for Madhura and Ghagra watersheds located in Barak basin in India. Drainage network for the watersheds and the geomorphologic parameters are estimated using 30m-ASTER DEM. Length and average slope values for the watersheds are estimated using GIS technique. UH peak characteristics values obtained is compared with earlier GIUH results, comparison of the results show that NRCS model when used with velocity factor estimated on the basis of length and slope characteristics give similar results. Incorporation of new velocity parameter estimation technique allows applying NRCS model to watersheds having no landcover data making it more useful for ungauged watersheds.

<p class="emsd"><span lang="EN-GB">A model for evaluating non damaging flow for a set of sub basins in a river system is presented. Linear Programming technique incorporating multiple inflows routing scheme is employed to evaluate upstream flow conditions necessary for satisfying specified downstream flood flow conditions. Non damaging flow for the sub basins are determined by using river system properties. The model is applied to a river system in India having flows from gauged and ungauged sub basins; flow contributions from the ungauged basins are estimated by using unit hydrograph technique. Peak flow studies involving major and minor sub basins indicate relative importance of the basins in the study area. Results obtained in the study depict variations in the non-damaging flow with the flow in the main channel. Model applications show that for flood with peaks exceeding 7566 m³/s regulating intervening basins only may not lead to safe flow at the downstream section(s). The model allows evaluating effectiveness of controlling the intervening basins in a river system; model applications to a real life river system yield results that are useful in adopting flood control measures for the study area.</span></p>

Potentiality of three organic manure namely vermicompost, farmyard manure (FYM) and poultry manure (PM) vis-à-vis, 0 per cent to100 per cent recommended dose of fertilizer-NPK in French bean (Variety: Arka Anoop). Field experiment was conducted in cluster form at Sihphir venghlun village, Aizawl district in Mizoram, NEH Region, India during the year 2015-16. Among the various treatments 75 per cent RDF along with 25 per cent RDF met from vermicompost along with bio-fertilizer (T 2) application produced better result in terms of germination per cent (85.34 %), number of pod per plant (20 number), pod yield per plant (300.05 g) and pod yield (14.00 t/ha). And was found to give more remunerative and advantageous in respect of maximum net return (Rs. 254000.00) and cost: benefit ratio (2.64) when compared to other treatments.
