Technology water and rainfall in doing to reduce soil water deficit in the soil. The technology is bio-pore that formed living things, such as soil fau-na and crop roots. This study uses a single factor randomized block design environment (RBD). The factor studied was the Bio-pore Infiltration Hole (BIH), which is filled with organic matter. The treatment was repeated 4 times, so that 20 experimental units were obtained. The treat-ments consisted of A (without BIH) as a control, B (BIH + Dry leaves), C (BIH + cow dung), D (BIH + chicken manure), and E (LR B + cow manure). Napier grass cropped with a spacing of 50 x 50 cm2 that was observed for variables of crop height, wet weight and dry weight of crops per bun-dle. The ground water content is measured with soil boring, and rainfall is measured with an ombro-meter. The study was conducted in the Experi-mental Garden of the Faculty of Agriculture, Sei Riam Village, Pelaihari Sub-district, Tanah Laut Regency, with a time of 2 months from November to December 2019. Rainfall in November and December was 127.85 mm and 637.8 mm with uneven distribution. The ground water content in treatments BIH + cow dung, BIH + cow dung, BIH + chicken manure, and BIH + cow manure is different from without BIH because it is without or-ganic matter so that its ability to retain water is small and its content is also less. Growth of crop height variable between 187.16 to 191.85 cm, wet weight in the range of 12.1 kg / m2 - a 14.9 kg / m2, and the dry weight in the range of 3.9 kg / m2 - 4.6 kg / m2, so treatments B, C, D, and E gave the best response compared to A which generates crop height about 172.78 cm, 7.3 kg / m2 wet weight and 2.4 kg / m2 dry weight.

Potato (Solanum tuberosum L.) is a tuberous crop from the Solanaceae family which is a source of starch and food to many in Nigeria, however, its production is being hampered in field and storage by bacterial pathogen which causes rot of the stored tubers. To this end, the study aimed at screening potatoes from different stores within Ibadan for the evaluation and diversity of bacteria pathogens responsible for rot in potatoes. Damaged stored potato samples were collected from different locations in Ibadan for studies, these samples were isolated for bacterial pathogen and characterized biochemically and observed under the microscope for identification. Three genera of bacteria were observed to be responsible for potato rot in the study and they include Pectobacterium carotovorum, Pseudomonas syringae and Ralstonia solanacearum. Of all the isolated bacteria, Pectobacterium carotovorum has the highest occurrence with a frequency of 60%, while Pseudomonas syringae has a frequency of 33% and Ralstonia solanacearum has a frequency of 27%. The pathogenicity of the isolates were tested and this revealed that Pectobacterium carotovorum is the most virulent with a severity score of 4.3, while Ralstonia solanacearum follows with a score of 3.3 and a score of 2.7 was recorded for Pseudomonas syringae, while the control had a score of 0. The diversity and differences shown in the isolated bacteria indicated that potato rot is a serious disease which is caused by different bacteria and need an integrated approach for its control from the field of harvesting to the storage house.

Smallholder agriculture of the Asian continent faces a significant challenge of declining soil productivity and an acute shortage of agricultural labor. Reduced tillage and crop residue mulch application is an integrated approach to preserving soil health and addressing the labor crisis to maintain farm sustainability. We undertook this study to evaluate the effect of strip planting and increased residue mulching on mustard and mungbean's productivity and profitability in northern Bangladesh during 2015 and 2016. Mustard cv. BARI Sharisha 14 and mungbean cv. BARI Mungbean 6 was grown following (i) Conventionally Tilled broadcasting method (CT) and (ii) Strip Planted line seeding (SP) with two levels of crop mulch (i) no-mulch and (ii) 50% mulch. The CT was done by a two-wheel tractor with four plowings and cross plowing followed by leveling. In SP, single tillage, seeding, fertigation, and field leveling were done simultaneously by a Versatile Multi-crop Planter machine. Results reveal that mechanized seeding of mustard and mungbean in SP with 50% residue mulching fetched 62% higher profit than broadcasted CT without residue through producing 24% higher seed yield. This practice reduced the land preparation costs by 68%, in association with reducing the labor and fuel requirements by 30%. Hence, it could be concluded that the mechanized seeding of mustard and mungbean with the retention of 50% of crop residue is profitable to the conventionally broadcasted seeding process.

Cucumber (Cucumis sativus L.) is a high nutritious and mineral-rich vegetable, which occupies a prominent place as a salad and vegetable. It is being used in many ways in the daily diet of humans and widely cultivated worldwide. The decrease of agricultural land, adverse environmental conditions and continuous increase of population, the demand of nutritious food is a matter of great concern to the world. Protected cultivation is a very effective tool to solve this problem because in this cultivation the productivity of crops is very high as compared to open field conditions. High value crops successfully grown in protected cultivation, specially vegetables (cucumber, tomato, Capsicum etc.) which are highly susceptible to the numerous pests and pathogens, including phyto-parasitic nematodes (specially root-knot nematode, Meloidogyne spp.). With this view, present trial was taken to estimate the avoidable losses caused by Meloidogyne incognita infecting cucumber in poly-house situated on farmer’s field with the application of phorate at 2 kg a.i. ha-1 over check. Results exhibited that application of chemical treatment significantly reduced number of galls per 5 g roots, egg masses per 5 g roots, eggs & juveniles per egg mass and final nematode population 79.03, 81.10, 30.91 and 56.54%, respectively. Avoidable yield losses were recorded to the tune of 66.84% on cucumber by M. incognita in poly-house.

The yield loss as a result of weed infestation is a major problem in maize fields. Hence, this research meant to examine the impacts of weed chemical control on maize growth and yield. The design of experiment was randomized complete block, and comprised 10 treatments viz., T1 (Control, weedy check), T2 (Weed free), T3 (Atrazine 1.5 kg ha-1 pre-emergence), T4 (Atrazine 750 g ha-1 + Pendimethalin 750 ml ha-1 pre-emergence), T5 (Atrazine 1.5 kg ha-1 followed by 2,4-D amine 0.4 kg ha-1 at 25 days after sowing as Post-emergence), T6 (Halosulfuron 67 g ha-1 at 25 DAS), T7 (Atrazine 1.5 kg ha-1 pre-emergence followed by Halosulfuron 90 g ha-1 25 days after sowing), T8 (Tembotrione 120 g ha-1 Post-emergence at 25 days after sowing), T9 (Pendimethalin 1000 ml ha-1 pre-rise fb Atrazine 750 g ha-1 + 2,4-D amine 0.4 kg ha-1 at 25 days after sowing as Post-emergence) and T10 (Atrazine 1.5 kg ha-1 pre-emergence followed by Tembotrione 120 g ha-1 Post-emergence at 25 days after sowing) with 3 replicates. The results showed that among other treatments, T10 recorded highest number of kernels per row (36.18), number of kernel cob-1 (499.12) and kernel weight cob-1 (136.97 g). A higher plant height (172.19 cm), leaf area (396.6 cm2 plant-1), dry matter accumulation (211.37 g plant-1), kernel yield (6.7 t ha-1) and stover yield (11.6 t ha-1) were found with weed free check plot which is on par with T10 treatment which brought about a higher value of plant height (162.93 cm), dry weight accumulation (205.7 g plant-1), leaf area (384.3 cm2 plant-1), kernel yield (6.5 t ha-1) and stover yield (11.4 t ha-1). In the meantime, T9 treatment reasonably increased kernel yield (6.2 t ha-1) and stover yield (11.0 t ha-1). It shows that application of herbicides as pre-emergence followed by post-emergence, such as T10 treatment could be a good method for weed control in maize fields.

Due to high demand of antibiotics for treatment of increasing bacterial infections there is an urgent need of engineering bacterial strains to get high concentration and meet industrial demands. Different techniques are being used for this purpose: which include over-expression of a gene in its host strain, engineering of different activators and regulators of antibiotic synthesizing gene cluster and expression of antibiotic gene cluster in heterologous host. The emergence of antibiotic resistant pathogens was a huge problem for existing medications and it urges a need or the development of novel antibiotics with high specificity. These can be produced by combinatorial biosynthesis or awakening of silent genes already present in bacteria. These advancements present a bright future of antibiotic production at industrial level.

Indonesia is one of the world's richest nations in terms of its biodiversity. One of the biological resources that has an important role in marine life is macroalgae. As a primary producer, macroalgae play an important role in the coastal environment. Porok Beach is a beach in the Gunungkidul district of Yogyakarta, Java Island, Indonesia. Porok beach is dominated by a rocky substrate, which would be the ideal substrate for macroalgae. The development of coastal areas as a tourism destination is feared to have an impact on macroalgae biodiversity. Comprehensive efforts are required to protect the coastlines of Porok Beach as sources of macroalgae germplasm that will ensure the survival of coastal biodiversity in Gunungkidul. So, it is necessary to study macroalgae diversity in Porok Beach to obtain a preliminary data to conserve. the macroalgae in the area. This study aims to monitor the presence of the macroalgae on Porok Beach. Purposive random sampling was used in the study, which took place on October 17th, 2020. Water temperature and pH are the ecological parameters that are measured. Seaweed specimens were collected only from those that were attached to the substrate (no floating specimens were collected) during low tide and then placed in ziplock plastic bags. Macroalgae species were identified to determine macroalgae species based on taxonomic keys using FAO species identification Guide for Fishery From the results of the study, Porok Beach was home to 17 species of macroalgae, eight of which were classified as Chlorophyta, 3 species are classified as Phaeophyta, and 6 species are classified as Rhodophyta.

Publisher : Future Science

This study was carried out to evaluate the effects of saline intrusion on agricultural activities, thereby proposing adaptation and mitigation measures for local people. Salinity was measured at 15 locations on the main and tributary rivers in Ke Sach district, Soc Trang province, Vietnam from January to September 2020. The method of direct interview with farmers was used to evaluate the knowledge and effects of saline intrusion on agricultural production. Salinity measurement results showed that salinity intrusion occurred and lasted from February to the end of May during the dry season (the Winter-Spring rice crop). During the rainy season (June-September), due to the large amount of water, salinity was only between 0.01 and 0.1‰. However, the research has found significant effects in the Summer-Autumn rice crop due to the accumulation of salinity in the soil from the Winter-Spring rice crop, which reduces the rice yield by 10-30%. The interview results revealed that more than 80% of the farmers were aware of the effects of saline water intrusion. Local authorities also regularly organize seminars to disseminate basic knowledge to the community to minimize the risks and impacts of saltwater intrusion. The proposed temporary solutions include rainwater storage, maintenance of saline prevention sluices, construction of more water regulation canals, financial support, and strengthening of salinity monitoring stations. In order to adapt to the long-term salinity conditions, local authorities need to focus on researching changing cropping patterns, crop structure, using new rice varieties that are able to adapt to drought and salty conditions. Besides, there will be technical assistance, capital for people to adapt well to the saline intrusion situation.

Journal of Agriculture and Applied Biology Vol 2 No 2 (2021): Journal of Agriculture and Applied Biology
Publisher : Future Science

This study aimed to investigate levels of copper in three commonly edible fruits, namely, Lycopersicon esculenta (tomato), Citrullus lanatus (watermelon) and Cucumis sativus (cucumber) traded in Dar es Salaam city. Also, the study scrutinized risk associated with heavy metal intake in the fruits. The fruits were collected from Buguruni Market, one of the biggest markets in the city, and thereafter, were processed, and analyzed to determine copper levels. The average daily intake and human health risk indices were calculated based on the obtained copper levels. The findings revealed that the mean levels and average daily intake in L. esculenta (0.3267 mg kg-1, 0.0279 mg kg-1 person-1) and C. lanatus (0.2523 mg kg-1, 0.0216 mg kg-1 person-1) did not differ considerably (p = 0.05) from each other while the two fruits had significantly higher values than C. sativus (0.1610 mg kg-1, 0.0137 mg kg-1 person-1). The copper levels and average daily intake values were below WHO/FAO and Tanzania Bureau of Standards permissible limits. The human health index (HRI) was in the order: L. esculenta > C. lanatus > C. sativus and all the values were less than unit, suggesting that there is no health risk from consuming the fruits. Concerning copper levels, the study concludes that the fruits are safe for human consumption.
