Abstract: Crop modeling is being popular in the field of agriculture as a precision tool for resources allocations and their effective utilizations. Two separate field and simulation studies were accomplished in maize and rice that were laid out in the two factor factorial randomized complete block design at Agronomy Farm of Institute of Agriculture and Animal Sciences, Rampur, Chitwan Nepal during spring and rainy season of 2007 and 2008, respectively. CERESmaize and rice models were calibrated using the best performing treatments (7.41 x 10 4 plants /ha for all 3 varieties of maize i.e. Rampur Composite, Upahar and Arun 4 and 160 kg N /ha for Prithivi and Sunaulo Sugandha, and 120 kg N /ha for Masuli varieties of rice). Models were validated using the remaining treatments (6.36, 5.56 and 4.76 x 10 4 plants /ha for all varieties in maize and 40, 80 and 120 kg N /ha for Prithivi and Sunaulo Sugandha and 40, 80 and 160 kg N /ha for Mansuli in rice) to predict growth and productivity of different varieties of maize and rice. Model calibration was done with the determination of genetic coefficients and validation was accomplished with the comparison of observed and simulated values on anthesis days, maturity days, leaf area indices, above ground biomass at maturity, unit weight, and grain yields for both maize and rice. The simulation results on nitrogen dynamics revealed that the nitrification and leaching losses were higher under the conditions of non-flooded maize whereas ammonia volatilization and denitrification losses were higher in the conditions of alternately wetting and drying flooded rice field. The degree and magnitude of N-loss is higher when the N-level is advancing under both field conditions. However, volatilization was almost nil in the non-flooded maize. Results indicated that CERESmaize and rRice models could be applied in simulating the agronomic management options including the efficiency of N-application under the conditions of availability of complete datasets required to run the Cropping System Models (CSM)-CERES-maize and rice models embedded under Decision Support System for Agro Technology Transfer (DSSAT) ver 4.2 in the coming days.

Abstract: A survey was conducted during June-July 2006 in Chitwan to find out the natural infestation of rice root-knot nematode ( Meloidogyne graminicola Golden & Brichfield) in rice nurseries. Thirty nurseries were surveyed and 100 seedlings from each nursery were evaluated. Field survey revealed that M. graminicola was widely distributed in most rice growing areas of Chitwan District. Rice root-knot disease was more prevalent in dry bed condition than wet bed. Most of the farmers grew seedlings in upland (dry) soil and there was more rice root-knot disease and second stage juvenile (J2) population in both nursery soil and seedling root. The galled (diseased) seedlings had significantly shorter roots and shoots. Most of the farmers did not know about the nematode problem and did not follow any management practices to control it in nurseries and/or in the main field. This indicated high risk of multiplication of the nematodes and huge loss in rice production. Thus, it is essential to manage M. graminicola in rice nurseries in order to produce healthy seedlings.

Abstract: These days, we see a tremendous change on business units through implementation of information technology equipment. The recent advances on technology have revolutionized technology and people start creating new ideas based on these advances. In this paper, we present an empirical study to investigate the impact of two internal and external factors on dynamic organizational skills through information technology equipment. The study uses a sample of 52 experts and using a questionnaire, we gather their insight about the proposed study. Structural equation modeling has been implemented and the results confirm that both internal and external factors influence dynamic organizational skills through information technology equipment. The study also uses freedman test to rank the factors and the results show that communication is the most important factor (4.41), followed by process (4.03), knowledge implementation (2.79), decision making (2.54) and human resources (1.22) is the last important factor.

Abstract: Rice ( Oryza sativa) is the main crop of Nepal. Farmers in Nepal mostly use seed from their stock in the form of informal seed systems which is around 92.3% of total seed requirements. In Nepal, formal seed of rice is distributed mostly by public institutions and very nominal amount by private seed dealers. Unavailability of quality seed of preferred variety is the key issue for rice seed systems. This study tries to attempt to address existing rice seed supply systems in Nepal thereby understanding its opportunities and constraints. The study was undertaken by collecting information from various documented sources and primary data from the household survey done at Chitwan and some seed related institutions during 2010/11. Formal and the informal are the two dimensions of the seed system for rice. Farm saved seed and farmers- to- farmers exchange of seed are informal seed system whereas private seed dealers and public institutions’ involvement in the seed sector are formal seed systems. Due to dominant of informal seed systems, there is the low seed replacement rate of 8.7% for rice. Nevertheless, breeder seed is solely produced by different Research Centers of Nepal Agriculture Research Council (NARC), whereas foundation seed is produced by NARC Research Centers and other institutes as well. This amount of source seed does not seem enough to cover rice areas of the country. To tackle problem of seed insufficiency, quality of source seed should be maintained by public institutions aside from creating awareness to farmers by service providers about the importance of producing certified seed by using foundation seed in farmers’ field.

Abstract: Rice-wheat system provides food, income, and employment to over 83 % of the people and contributes to national food security in Nepal. Sustainability of the system is under threat because of increasing cultivation cost and declining soil fertility. On-farm experiments were carried out to determine the effects of tillage and crop establishment methods, crop residue management, and nitrogen levels that affect soil attributes and productivity of the rice-wheat system during 2010- 2011at Bara, Nepal. The treatment consisted of three tillage and crop establishment methods viz. Conventional tillage (CT), Permanent bed planting (PB), and Zero-tillage (ZT); two residue management levels viz. Residue retention and Residue removal; and three nitrogen levels viz. Zero nitrogen, farmer’s dose (80 and 100 kgha-1 N for rice and wheat, respectively), and abundant nitrogen (120 kgha-1 N for both rice and wheat crop). The experiments were laid out in strip-split plot design with three replications. The research results revealed that rice grain yield was significantly higher in the plots receiving N level as applied by farmers that was similar to abundant nitrogen dose. Wheat grain yield was significantly higher with zero tillage compared to permanent bed planting and conventional tillage. Significantly higher wheat grain yield was also obtained due to abundant nitrogen dose than zero dose nitrogen which was similar to farmers’ dose of N as well. There was no significant difference in grain yield of rice and wheat due to residue retention, although, it improved soil moisture. In wheat crop, zero-till planting and increased nitrogen application conserved soil moisture, enhanced soil electrical conductivity and lowered soil temperature. It can be concluded that rice and wheat can be grown successfully with zero tillage and farmer’s nitrogen dose without any yield penalty.

Abstract: Decision support tools for non-destructive estimation of rice crop nitrogen (N) status (e.g., chlorophyll meter [SPAD] or leaf color chart [LCC]) are an established technology for improved N management in irrigated systems, but their value in rainfed environments with frequent abiotic stresses remains untested. Therefore, we studied the effect of drought, salinity, phosphorus (P) deficiency, and sulfur (S) deficiency on leaf N estimates derived from SPAD and LCC measurements in a greenhouse experiment. Linear relations between chlorophyll concentration and leaf N concentration based on dry weight ( ) between SPAD values adjusted for leaf thickness and and between LCC scores adjusted for leaf thickness and could be confirmed for all treatments and varieties used. Leaf spectral reflectance measurements did not show a stress-dependent change in the reflectance pattern, indicating that no specific element of the photosynthetic complex was affected by the stresses and at the stress level applied. We concluded that SPAD and LCC are potentially useful tools for improved N management in moderately unfavorable rice environments. However, calibration for the most common rice varieties in the target region is recommended to increase the precision of the leaf N estimates. 1. Introduction For more than a decade, considerable efforts have been made to develop and establish improved nutrient management options for rice (Oryza sativa L.). The goals were concepts and tools allowing site- and season-specific (i.e., real-time) adaptation of nutrient management recommendations [1]. These efforts resulted in technologies contributing considerably to increased productivity of Asian rice farmers, improved use efficiency of scarce and expensive resources, and reduced detrimental environmental effects [2]. However, these developments are mostly limited to irrigated systems because the improved nutrient management technologies did not target rainfed rice systems. But recent developments show that, because of the increasing availability of input responsive varieties for rainfed lowlands [3], these environments are characterized by the fastest yield growth rates, often enabled by increasing fertilizer use. Therefore, improved fertilizer technologies are also needed for rainfed lowlands in order to increase the productivity of rice farming in these environments to maximize the efficiency of fertilizer use and to minimize negative environmental side effects of such practices. Nitrogen (N) as the most commonly used fertilizer element and the one limiting growth in the majority of

Abstract: The diverse physiographic and hydrological regime has booned Nepal with high potential of water resource projects. But these projects depend highly on hydrological data for which hydrometeorological stations need to be established. Their establishment, because of difficult topographic feature of Nepal and the high cost of installation, operation and maintenance, becomes feasible only for big projects. And thus hydrological data are needed to be predicted for small scale projects. These predictions for a given ungauged river system at particular location are facilitated by empirical methods such as WECS/DHM (Water and Energy Commission Secretariat/ Department of Hydrology and Meteorology) and MIP (Medium Irrigation Project) which have been used since its development without upgrading and checking its reliability. The objective of this study is to compare the anomaly of flow predicted by WECS/DHM and MIP method and determine reliability of minimum flow predicted by the methods. The anomaly of the method is presented by comparing the mean DHM monthly flow with the mean of predicted monthly flow for each of the seven rivers from Central and Western Development Region. Both methods give variable deviation for different periods of time for all the rivers. MIP method gives reliable prediction only if the discharge measurement is done during the dry period (November–April). The reliability of these methods is checked for estimating minimum flow by calculating the percentage of time discharge (minimum predicted flow) will be exceeded. WECS/DHM has given higher reliability for the minimum flow than MIP method. MIP (D) method has given good approximation to the DHM dry period flow than MIP (A). While analyzing the low flow, lower predicted value given by either of these methods when used gives good approximation. In order to improve the accuracy of prediction there is requirement of modification of these Hydrological Analytical tools.
