Wheat (Triticum aestivum L.) is one of the most important staple food crops all around the world. It belongs to the family Poaceae. It has high dietary fiber content and is the good source of carbohydrate due to which it has wide cultivation in the entire world. It is the 3 rd most cultivated commercial crop in Nepal. It is most popular among terai region due to suitable climate and irrigation supply. Wheat is generally a winter season crop and its growth and yield highly depends upon various factors where sowing time and irrigation requirements are the major ones. Wheat sown at appropriate time with average water supply and minimum to average temperature contributes to high wheat production. Sowing in time leads the wheat to absorb adequate sunlight and harness it for increasing the production. Similarly ,6-7 irrigation supplied during the growth contributes to higher yield and good grain quality of wheat. With the advancement in technology improved seeds have been introduced in Nepal which are disease resistant. But still water stress resistant wheat varieties have not been introduced and researches are going on. So, sowing on time and providing irrigation is very important for good response of growth parameters and to attain maximum productivity of wheat.

Planting a crop with high productivity and quality while ensuring the continuity of good soil quality and environmental sustainability is important. With the changes of climate and extensive anthropogenic activities, soil had become undesirable for crops planting. However, various measures can be done to improve this such as applying suitable types of fertilizer and soil amendments besides monitoring the quality of soil continuously. Fertilizer application in a way is helpful in providing essential nutrients needed by the plant while soil organic amendment able to improve its quality through biotic and physical changes. In this study, different combination of treatments was applied in two different types of soil to observe its effect on morphological growth of water spinach (Ipomoea aquatica), soil pH, and total organic carbon (TOC) in soil. Field experiment was conducted at Glasshouse Nursery Complex (GNC), International University Malaysia for five weeks. Combination of treatments consist of control (T1), biochar (T2), chicken manure (T3), combination of biochar and chicken manure (T4), and combination of biochar, chicken manure, and NPK fertilizer (T5). Two types of soil that were used in this study which are normal topsoil and oxisols type of soils. Results showed that the T5 were observed to have the highest average of plant grown in both normal top soil and oxisols soil. The pH of both soils treated with biochar and organic manure increased compared to control which reflect a positive effect towards nutrient availability for plant. Total organic carbon content also showed an increased trend with soil amendment and fertilizer applications. Hence, in overall growth of Ipomoea aquatica improved with application of fertilizer and organic amendments.

Intercropping is a farming practice involving two or more crop species, or genotypes, growing together and coexisting for a time. On the fringes of modern intensive agriculture, intercropping is important in many subsistence or low-input/resource-limited agricultural systems. Intercropping in order to improve land use efficiency, take advantage of intercropping facilitation and improve economic benefits. Also, linked with the higher yield, the associated higher amount of cereals-legume by-product is preferred for animal feed or human consumption. The objective of this study is to find out the suitable groundnut – maize intercropping system and increase productivity, economic and nutritional development of charland farmers of Bangladesh. In the experiment, intercropping system such as One row of maize in between two normal rows of groundnut, one row of maize (leaf cutting at the age of 115 days) in between two normal rows of groundnut, which was compared with sole maize, Sole maize (leaf cutting at the age of 115 days) and sole groundnut production. Total yields of maize /groundnut intercropping were higher than that of sole maize and groundnut. Maize /groundnut intercropping is the efficient use of light because of complementary use of space between the maize plants and the groundnut plants. Maize /groundnut intercrop gross return and BCR per hectare were found higher than from sole crop system. The total yield of intercropped crops was greater than sole cropping shown by LER>1. The overall advantage of intercropping ranged from 73 to 86%. The highest land equivalent value of 86% was recorded from paired row maize (leaf cutting at the age of 115 days) in between four normal rows of groundnut sowing arrangements indicated a yield advantage of 86% over sole crop.

The agriculture sector has been facing challenges due to climate change particularly increasing global water scarcity which threatens irrigated low land rice production. Alternate Wetting and drying (AWD) is a water management system where rice fields are not continuously submerged and the fields are allowed to dry intermittently during the rice-growing period. AWD technique is a necessity for modern farming of rice as it is profitable over the continuous flooding irrigation system which prevents the wastage of scarce and vital water resources, irrigation cost and protects the environment from degradation. It also protects human health from diseases like Malaria as there is an absence of continuous flooding for the mosquito to lay eggs. It helps to enhance food security by increasing the production, nutrient content, and minimizing the toxic elements in rice. However, if this technique is not done properly in the field from time to time, we can also get negative impacts. It varies according to soil condition, irrigation timing, environment, etc.

Tuta absoluta (Meyrick), the tomato leaf miner, is one of the most key pests affecting tomato crops in Bangladesh and causes damage up to 90% yield loss, and very difficult to control. An open field research was conducted in the Arboriculture Centre, Bangladesh National Parliament, Sere Bangla Nagar, Dhaka, Bangladesh during December 2017 to April 2018 on the management of tomato leaf miner using ten selected bio-rational insecticide based IPM packages viz. Emamectin benzoate + removal of instead leaf & fruit, spinosad + removal of infested leaf & fruit, abamectin + removal of infested leaf & fruit, emamectin benzoate + abamectin, spinosad + buprofezin, abamectin + buprofezin, emamectin benzoate + lufenuron, buprofezin + removal of infested leaf & fruit, buprofezin + lufenuron and lufenuron + removal of infested leaf & fruit along with an untreated control. The experiment was laid out in Randomized Complete Block Design (BCBD) with three replications of each treatment. The effectiveness of IPM packages was evaluated based on following parameters namely percent leaf and fruit infestation, percent protection of leaf and fruit over control, marketable and infested fruit yield (t/ha), percent increase or decrease of marketable or infested fruit over control. All the IPM packages significantly reduced percent leaf and fruit infestation and significantly increased/decreased the marketable/infested fruit yield, respectively over untreated control at 7 days after spraying (DAS). Of different packages, the best results were observed in case of emamectin benzoate + removal of infested leaf & fruit (84.83% and 86.54% leaf and fruit, respectively protection over control; marketable fruit yield of 46.60 t/ha and 71.67% reduction of infested fruit yield over control) treated plot whereas the lowest protection was obtained from lufenuron + removal of infested leaf & fruit (34.95% and 37.33% leaf and fruit, respectively over control; marketable fruit yield of 26.49 t/ha and 11.36% reduction of infested fruit yield over control) treated plots. Therefore, emamectin benzoate + removal of infested leaf & fruit could be recommended as the IPM packages for the sustainable management of tomato leaf miner, Tuta absoluta.

The study was conducted from February to May, 2019 to assess the status of farm mechanization of Rice cultivation in Ratuwamai municipality Morang, District Nepal. Altogether 80 respondents were selected by using simple random sampling technique from the sampling frame of 400 populations. Pre-tested interview schedule, Focus Group Discussion(FGD) and key informant survey (KIS) were used to collect primary information from the respondents ,while secondary information were collected by reviewing different relevant publications to find out the mechanization activities conducted in rice cultivation, perception of farmers regarding farm mechanization and the constraints and factors affecting adoption of agri- mechanical equipment .The data were processed and analyzed using descriptive and inferential statistics through MS-excel and SPSS .Chi-square test was done to test the significance difference between dependent and independent variables. The result of the study shows majority of the respondent were male, and majority were involved in agriculture as their major occupation. Majority of the respondents were found literate and very few respondents were involved in commercial farming. The study reveals about eighty percent of the respondents were adopter of machineries. During nursery preparation and transplantation no any machineries were employed, during land preparation 86.25 percent respondents have adopted machineries. The harvesting stage was found more mechanized than other stage as 68.75 percent respondents use machines. The use of thresher and combine harvester was found more common during this stage. Chi-square test shows the association between adoption level of machineries with training, subsidies and education level has positive and significant relationship. Regarding perception sixty five percent respondents found mechanical method more beneficial and fifty five percent use unskilled manpower during rice cultivation. Only 22.5 percent respondents had their own machines and majority use machine based on pre-booking. Agriculture knowledge centre (AKS) was found as major source of information on mechanization. Among many constraints during adoption of machinery high land fragmentation was agreed by majority of the respondents. The study revealed that, among the production problems, unavailability of quality seeds and fertilizers in required quantity and time appeared as the most important production problem followed by lack of subsidy on irrigation, disease and pest infestation, lack of technical guidance and labour shortage was appeared as least problem.

Climate change has caused serious effect on agriculture production. The global population is increasing and to meet their demand for fuel, food, and fiber, Farmer should adopt sustainable agriculture practices which provides resilience to climate change and uplifts the farmers’ livelihood. Climate-smart agriculture practices are taken as eco-friendly practices that help to enhance production sustainably with minimum effect on resources and environments. These practices include No-tillage, reduced tillage, Intercropping, integrated pest management, Rainwater harvesting, use of information and communication technology, etc. As women are an integral part of agriculture production and are more vulnerable to climate change, the Gender-responsive approach needs to be addressed which helps to close the gender gap in agriculture. Nepal, as a vulnerable country in terms of climate change, is adopting different programs and policies at the national and local level to tackle climate change. Climate-smart villages(CSV) in Nepal are practicing different CSA practices at the farm level to secure foods and livelihoods.

Black rice is considered as super food due to its various health benefits to the human being. In Bangladesh this rice is cultivated in a very limited area of Chittagong hill tracts and its cultivation technique in plain land ecosystem is still unknown. Therefore, a study was undertaken to evaluate the performance of few black rice cultivars cultivated year-round in plain land environment. The experiment was performed at the Agronomy Field Laboratory of Bangladesh Agricultural University, Mymensingh. The experiment comprised two factors viz. A) three rice cultivars: Kongnam ene, Gelong ni and Gelong se; and B) Twelve date of transplanting starting from 01 July 2018 to 01 June 2019. The experiment was laid out in a split plot design where date of transplanting was distributed in main plots and rice cultivars were allocated in sub plots. It has been found that cultivar Kongnam ene can be cultivated as a short duration variety as it required only 40 days to panicle initiation, 60 days to flowering and 80 days to harvesting after transplanting. All the three cultivars can be cultivated in all the three seasons viz. aus, aman and boro. The cultivar Gelong ni produced significantly highest grain yield (4.0 t/ha) among the cultivars when transplanted in January (boro season).

The cultivar Gelong ni produced significantly highest grain yield (4.0 t/ha) among the cultivars when transplanted in January (boro season).","PeriodicalId":134753,"journal":{"name":"Tropical Agrobiodiversity","volume":"452 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116156537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Marigold species are famous around the world and grown for its different purpose like beautification, to extract pharmaceuticals products, loose flowers, and cut as well. Among the many species of marigold Tagetes erecta L. is one of the famous species grown in Nepal. Pinching in marigold is a process of increase in flower yield through the diversion of energy through breaking apical dominance in plants. Pinching increases the flower yield (96.78 q/ha) compared to non-pinching (68.78 q/ha) (Rathore et al., 2011) in marigold.
万寿菊在世界各地都很有名，种植它有不同的目的，比如美化、提取药品、散花和切割。万寿菊(Tagetes erecta L.)是尼泊尔著名的万寿菊品种之一。万寿菊的捏花是通过打破植株的顶端优势来转移能量以提高花朵产量的过程。与不掐花(68.78 q/ha)相比，掐花增加了万寿菊的花朵产量(96.78 q/ha) (Rathore et al.， 2011)。

This study was carried out at Subarna Agro-Based Initiative’s (SABI) field, Noakhali, Bangladesh during the period of Rabi Season, 2018. The objectives of this study were to evaluate the growth and yield performances of okra in different types of organic fertilizers and to identify the possible fertilizer treatment which enhances both growth and yield of okra [Abelmoschus esculentus (L.) Monech] .BARI Okra-1 was taken for the study. A Randomized Complete Block Design (RCBD) was used and there were 4 treatments namely; Farm Yard Manure (T1), Vermi-Compost (T2), FYM + Vermi-Compost (T3) and Integrated Nutrient Management (T4) were replicated three times. Plant height (cm), number of leaves, total flower, total number of fruits, fruit length (cm) and fruit weight (g) data were taken as parameters on the growth and yield of the plant. Though fruit weight was observed higher for the effect of T3 (72.78 g) but in case of Integrated Nutrient Management (T4) the other characters such as plant height, number of leaves, total flowers, total number of fruits, fruit length were observed higher. The T4 showed a comparatively better result of growth and yield than other treatments. This study clearly indicated that Integrated Nutrient Management which contains the micronutrients with minimum inorganic and organic manure may be a potential source for better growth and high yield in okra.
