“…The distribution of available boron was very low only ( Figure 11). The very deficient status of available boron was also reported by Khadka et al (2016Khadka et al ( , 2017Khadka et al ( , 2018 during their study in the different sites of Nepal. The intense cultivation of crops without application of boron containing fertilizer might be the cause of deficient status of available boron in the field.…”

“…During crop growth they do not think about how much element present in the soil, and how much amount should have to apply. In most of the sites of Nepal, soil organic matter is in extremely critical as well very acidic due to unmanaged farming (Khadka et al, 2016(Khadka et al, , 2017(Khadka et al, , 2018. The soil fertility evaluation is the most basic decision making tool in order to efficient plan of a particular land use system (Havlin et al, 2010).…”

Knowledge about the soil fertility status and mapping their spatial distribution play a crucial role for sustainable planning of particular area. Thus, a study was conducted to assess the soil fertility status of the Agricultural Research Station, Bijayanagar, Jumla, Nepal. The farm is situated at the latitude 29.273656°N and longitude 82.180967°E as well altitude 2370masl. The total 18 samples were collected randomly at a depth of 0-20 cm by using soil sampling auger. A GPS device was used for determination of geographical position of soil sampling points. The collected samples were analyzed following standard analytical methods in the laboratory of Soil Science Division, Khumaltar. The Arc-GIS 10.1 software was used for the soil fertility distribution mapping. The observed data revealed the structure was sub-angular blocky, whereas colour were dark grayish brown and very dark brown. The sand, silt and clay content were ranged 27-47%, 33.10-61.10% and 11.90-23.90%, respectively and categorized loam and silt loam in texture. The soil pH was moderately acidic to moderately alkaline (5.45-7.66) and very low in available boron (0.01-0.28 mg/kg) and sulphur (0.59-6.23 mg/kg). Moreover, very low to very high available iron (15.90-300.50 mg/kg), very low to high available manganese (1.46-12.88) and low to high organic matter (2.07-6.53%). Similarly, medium to high total nitrogen (0.14-0.23%), available potassium (40-255 mg/kg) and zinc (1.12-8.26 mg/kg). Correspondingly, high available calcium (1632-2880 mg/kg) and magnesium (98-456 mg/kg), and very high available phosphorus (64.2-257.2 mg/kg) and copper (2.58-12.16 mg/kg). The determined soil test data can be used for sustainable soil management as well as developing future research strategy in the farm.

“…The site is located in the central piedmont of Nepal at 120 m above mean sea level at 27°21′N and 84°53′E. The soil is with pH 5.67, i.e., moderately acidic (Bhurer, 2013;Khadka et al, 2018).The soil is an Inceptisol formed on Himalayan residuum. The area has a subtropical climate highly influenced by the southwestern monsoon.…”

In order to reach an optimum and sustainable production, growers must know the fertilizing nutrient sources and their application rates. The present study aimed to determine the effect of different organic and inorganic source of fertilizers on growth and performance of rice. A field experiment was conducted at Regional Agriculture Research Station, Parwanipur, Bara, Nepal during summer season of 2013. Rice variety ‘Hardinath 1’ was used in these experiments. Treatments included a combination of organic and inorganic nutrients at eight rates (control, recommended dose of NPK, ½ NPK+FYM 10 t ha-1, ½ NPK+20 cm crop residue, ½ NPK+Chicken manure 10 t ha-1, ½ NPK+Vermicompost 10 t ha-1, FYM 10 t ha-1 and FYM 20 t ha-1).The experiments were laid out in Randomized Complete Block Design with four replications. Treatments produced significant results for plant height, number of tillers per square meter, panicle length and grain yield but thousands grains weight was insignificant. Result showed that application of half of recommended N: P2O5: K2O from the inorganic fertilizer sources along with soil incorporation of 20 cm crop residue produced significantly higher value for plant height, number of tillers per square meter, panicle length and Grain yield. Treatments did not produce significant effect on after harvest soil properties: pH, organic matter, nitrogen, phosphorus and potassium content.

“…From 1971 to 2014, the average minimum and maximum temperature of 18.4 and 30.5°C with an average annual rainfall of 1692.3 mm were recorded for this site (DHM 2017). Khadka et al (2018) found that the soil at the Simara site was moderately acidic in pH (5.67 ± 0.09), low in organic matter (0.74 ± 0.04%), and available Sulfur (0.8 ± 0.1 ppm). The sand, silt, and clay contents were 24.41 ± 0.59%, 54.57 ± 0.44%, and 21.03 ± 0.32%, respectively and categorized as silt loam and loam in texture.…”

This study examines the seasonal and diurnal variations of carbon dioxide and energy fluxes over three land cover types of Nepal by using the eddy covariance method from March to November 2016. The surface energy balance closures were moderate with the values of about 56%, 61%, and 64% closure at Kirtipur, Simara, and Tarahara sites respectively. The monthly average values of net radiation flux and latent heat flux peaked in August at Kirtipur and Tarahara sites whereas in June at the Simara site respectively. The maximum monthly average measured sensible heat flux was 37 W m −2 , 43.6 W m −2 , and 36.3 W m −2 in April for all the sites whereas soil heat flux was 5.1 W m −2 and 2.9 W m −2 in April for Kirtipur and Simara sites and 6.2 W m −2 in June for the Tarahara site. The magnitude of diurnal peak of net ecosystem CO 2 exchange (NEE) reached up to 11.04 μmol m −2 s −1 at Kirtipur, 15.04 μmol m −2 s −1 at Simara, and 10.44 μmol m −2 s −1 at Tarahara sites respectively. Among the three study sites, the ecosystem at the Kirtipur site was a good carbon source; the ecosystems at Simara and Tarahara sites were low and good carbon sink in the growing season. In addition, all three different land cover ecosystem were carbon source when accounted for the measurement period.
