    Assessing productivity and profitability of hybrid maize using nutrient expert® model set in Jhapa.
    (Institute of Agriculture and Animal Science (IAAS), Lamjung, 2015-06) Chauhan, Swastika
    Maize is second important food crop in Nepal and its demand is increasing year by year. However, its productivity is constrained by a number of problems out of which site specific nutrition management is the most important one. Therefore, a field experiment was conducted on a farmer’s farm land at two district of Jhapa viz.Dhukurpani and Gauradha using Nutrient Expert® Maize model from 28th November 2014 to 17th May 2015. The research design was Randomized Completely Block Design with 3 treatments and 11 replication. Three treatments are NE (Nutrient Expert recommendation), GR (Government recommendation), and FP (Farmer practices). Significant difference in terms of no. of plant/m2, kernel no. /row, shelling%, test wt. and Yield at 15.5% moisture was found. Heighest yield (11.99 ton ha-1) was obtained from NE field which was followed by GR (8.67ton ha-1) and FP (7.31ton ha-1). NE based practices gives (4.68 ton) more yield and (Rs. 93545.05) more gross revenue than FP andwith comparision to GR it produced (3.32 ton ha-1) more yield and (Rs. 66404.24) more gross revenue. Comparison of Nutrient Expert® (NE) estimated attainable maize yield and gross revenue given by Nutrient Expert® hybrid maize model versus actual maize yield and gross revenue in farmer field trail NE-based fertilizer recommendations proved to be successful in reaching the yield targets estimated by the software. The actual maize yields recorded in farmer fields were higher than the NE estimated attainable yields. NE recommendation was found better over GR and FP. Higher yield and profitability from hybrid maize was obtained from NE based recommendation.

    Effect of pest exclusion net and mulching on okra production at Rampur, Chitwan, Nepal
    (Faculty of Agriculture, Agriculture and Forestry University, 2020-11) Chauhan, Swastika
    This study entitled 'Effect of Pest Exclusion Net and Mulching on Okra Production at Rampur, Chitwan, Nepal' was conducted at Horticulture Farm of Agriculture and Forestry University, Rampur, Chitwan, Nepal from May, 2018 to August, 2018. The experiment was laid out in a randomized complete block design having five treatments namely i) Control (No net + no mulch) ii) Organic mulch (Rice straw mulch) iii) Black plastic mulch iv) Silver plastic mulch v) Pest exclusion net + black plastic mulch. Swastik-2 F1 variety was selected for the study. Recorded data were analyzed using R-software (R version 3.5.3), MS Excel 2016 and Minitab 18. The result revealed that silver plastic mulch and black plastic mulch treatment resulted in significantly higher yield (30.74 and 29.39 mt/ha respectively), leaf number per plant (27.98 and 26.73), branch number per plant (5.1 and 4.8), fruit number per plant (33.65, 29.77) and the lowest days to flowering (38.5 and 39.75 days) while PEN+black plastic mulching treatment resulted in higher stem diameter (25.41 mm), higher plant height (212.93 cm), longest days to flowering (43 days), higher fruit length (18.26 cm), higher fruit diameter (17.34 mm), higher fruit weight (32.80 gm) , the lowest leaf number per plant (15.58), the lowest branch number per plant (3.85), the lowest yield (20.4 mt/ha) and the lowest light intensity (110.32 lux). There was no significant difference in yield between black plastic mulching and silver plastic mulching. Correlation study on yield attributing factors also revealed that yield of okra is positively and significantly correlated with leaf number per plant (0.984), branch number per plant (0.962), fruit number per plant (0.972) and soil temperature (0.899). Similarly, days to flowering was found negatively and significantly correlated with yield (-0.985) of okra. Plant inside PEN+black plastic mulching which received low light intensity had higher vegetative growth but found with low yield. Plant in control and straw mulch treatment were found with both low vegetative growth and yield. The cultivation with silver plastic mulch and black plastic mulch were economically more viable as compared to other treatments. in Chitwan.
