    Phenological study of a fruit tree is important for timely and proper orchard management. This study was carried out in orchard located at Warm Temperate Horticulture Centre (WTHC), Kathmandu, Nepal from January to August, 2020 with the objective to identify the different timing of phenological stages in 18 different varieties of pear. Data on days from swollen bud to bud burst, swollen bud to green cluster, swollen bud to white bud, swollen bud to bloom, swollen bud to petal fall, swollen bud to fruit set, fruit length, and fruit diameter were recorded. The phenological and fruit traits were found highly significant. The shortest flowering period (days from swollen bud to petal fall) was observed in varieties Sinko and Yakumo (13.33 days) and the longest period was found in Pharping local (Green) (35.00 days) followed by Pharping local (Brown) (34.00 days). The longest fruit (58.80 mm) was recorded in Anjou followed by Bartlett (52.90 mm) and Yakumo (49.80 mm). Similarly, the highest fruit diameter (57.60 mm) was recorded in Anjou followed by Yakumo (55.80 mm) and Atago (51.60 mm). On the basis of total variability, pear varieties were grouped into five distinct clusters.  Cluster 2 showed that Anjou had the highest fruit length and fruit diameter. Cluster 5 illustrated that the longest flowering period was observed in the Pharping local (Green) followed by Pharping local (Brown). Based on phenological traits Sinko and Yakumo and based on fruits traits Anjou were found potential varieties for cultivation under warm temperate region of Nepal

    Liquid organic fertilizers can come from feces (animals, humans), agricultural waste, agricultural processing waste, household waste, urban waste, and production waste. Waste in general is a case of environmental pollution which can cause environmental problems and deteriorate health for the community, this is caused by liquid waste obtained from various industrial activities, hospitals, markets, households, especially in food industry waste, because in the process it still leaves elements that can become part of the process water and discharged into the environment. The use of various wastes to become organic fertilizers is an effort to overcome the problem of environmental pollution, with high organic matter, waste can act as an organic source of food by microbial growth. The purpose of this study was to determine the various POC materials from organic waste that would have a better effect on growth and yield in lettuce plants. Based on the results of the study, it can be concluded as follows:There is a significant effect on plant length variables on wet weight per plant with R Square of 0.69884 (69.88%) at 28 days of age observation and number of leaves with R Square of 0 , 7025 (70.25%) at 35 days after transplanting and there was a significant effect of the K3 treatment (POC 12%), plant length and number of leaves on the wet weight per plant which gave a higher value than the K1 and K2 treatments with Adjusted R Square of 0.935293 (93.53%); but statistically not significant difference with treatment K2 (POC 8%) with Adjusted R Square of 0.706472 (70.65%)

    The disaster in Karo District due to the eruption of Mount Sinabung on September 15, 2013 has claimed lives, damage to homes, agricultural land and property. This affected the economic and social conditions of affected farmers, so the government intervened to improve these conditions through a rehabilitation and reconstruction program. The purpose of this study is to compare the economic and social conditions of the community before and after the eruption of Mount Sinabung due to rehabilitation and reconstruction activities and examine community participation in recovery activities. The analytical method uses the non-parametric Wilcoxon Signed Rank Test, with two related samples namely the measurement of conditions before the disaster and after the post-disaster rehabilitation-reconstruction are not mutually free. The results show that the land owned by respondents after the disaster was reduced, but land tenure by respondents increased because they rented land elsewhere. The types and number of livestock have decreased such as buffalos and chickens, but cattle have increased due to the aid in purchasing cattle. Money capital has increased because of the provision of financial assistance from the private sector or government. The number of kiosks and sales turnover increased with the change of the area around the disaster into a tourist destination. Likewise, farm family income has increased with the new arable land in Siosar which is planted with vegetables in addition to the results of coffee on the old land that is ready to harvest. Resilience of respondent faces disaster and willingness to rise from disaster in the category of vulnerable and increasing. Work ethic in the high category increases, but in the medium category it actually decreases. The dependency of aid from the government in the high category increases, but in the low category it decreases

    The area of rainfed lowland rice in Indonesia was 3,292,578 ha or 24% of the total area of rice, but the used is still very small, so that opportunities are still open for the development of rice plants. The main constraints on rainfed lowland are drought stress and inefficient use of nitrogen (N) and phosphorus (P) nutrients. The purpose of this study was to determine the effect of mycorrhizal fungi on the efficient use of nitrogen and phosphorus in rice planted in rainfed lowland. This research was conducted in rainfed lowland in April to July 2019 in the village of Demangan, Sambi, Boyolali, Central Java. The research method was a randomized completely block design. Factor 1: Doses of nitrogen fertilizer (N) 0; 45; 90; 135 kg/ha. Factor 2: phosphorus dose (P) 0; 25; 50; 75 kg/ha. Observations included the number of total tillers, number of productive tillers, panicle number, panicle length, 1000 grain weight, and grain weight per plot. Data Analysis was analysis of variance. If there was a difference between treatments then it was tested further by using Duncan's New Multiple Range Test  at 5% level. To know the relationship of direct and indirect influence, regression and correlation analysis were done. Data were analyzed by computer using SAS for window 9.0 programs. The results showed that the application of VAM could save the use of nitrogen fertilizer and eliminate the use of phosphorus fertilizer

    Improving household well-being by intensifying agricultural production is a major concern of most developing countries. Our main objective is to quantify the contribution of Cameroon Penja pepper production on economic well-being. With the used of multiple correspondence analyses we constructed a well-being indicator using primary data collected among pepper producers and the result is estimated using ordinary least square. The results show that Penja pepper production is significantly corroborating with household economic well-being. The result is explained by industrial pepper production, while climate change, financing difficulties and availability of cultivated land are the main constraints faced by Penja pepper farmers. Decision makers should create policies to regulate the pepper market in terms of exportation of the crop. This is a wise step towards increase household economic well-being

    The aim of this research to improve the productivity of a local variety of chickpea by enriching the soil produced indigenous microorganism (IMO) and reducing the rate of nitrogen fertilizer. The experimental design used in this study was randomized complete block design with three replications. In this research, the soil was enriched with indigenous microorganism with different rates.The treatment combinations were soil with three different rates of IMO (Soil + 0, 2 and 4Tbsp of IMO) .The N fertilizer used in this study was installed in three different rates (0, 30 and 60 ppm NFR) in form of Urea in water) each rate of NFR was measured according to the weight of the soil in the pot. Morphological characters and yield component were determined in this research. The morphological characters included the height of plant, number of branches, days to 50% flowering (days), days to physiological maturity (days) and yield components were:   pods number /plant, seed number/plant, seeds weight/plant (g), hundred seed weight (g) and grain yield (kg/ha). The result illustrated that the main effect of IMO gave maximum plant height, number of branches, number of pods/plant, number of seeds/plant, weight of seeds/plant, hundred seeds weight and grain yield. The combination of IMO and NFR under treatment of (Soil + 4Tbsp IMO) with application of 30 ppm NFR also gave highest value of each of morphological characters and yield components. The result of this study demonstrates that enriching soil with 4Tbsp optimize the rate of N fertilizer to 30 ppm
