Effect of seed size and pod position of clove (Syzigium aromaticum) to seed viability

Cloves are commonly propagated generatively using true seed. One of the factors causing the lack of qualified clove seeds is farmers^ low awareness of using high-quality seeds. Farmers usually do not produce seeds- in particular, they obtain seeds from their trees without exclusively separating trees for making seeds and flowers. The seeds are randomly harvested from all the flowers without considering the pod position and size. This study aimed to evaluate the effect of pod position and size on clove seed viability. The research was conducted at the Glass House of Indonesian Spices and Medicinal Crops Research Institute, Indonesia, from August to December 2018. The study was arranged in a completely randomized design with two factors. The first factor was the seed size: large (≥ 0.9 g) and small (< 0.9 g). The second factor was pod position : (a) the pods exposed to the morning sun, (b) the pods exposed to the afternoon sun, and (c) the pods’ unexposed sun (hidden). The pods originated from selected mother trees from Kayu Aro, West Sumatra. The results showed that seed size ≥ 0.9 g and pods exposed to the morning sun had higher viability, as indicated by the high seed growth rate, vigor, and better plant growth than other treatments.

Building Agricultural Knowledge of Soil-biodegradable Plastic Mulch

The use of polyethylene (PE) mulch causes environmental pollution where incomplete removal leaves fragments susceptible to escape to ecosystems, such as the ocean, where they can cause ecological harm. PE mulch is generally nonrecyclable due to contamination with soil and crop debris after use, leaving growers with few end-of-life options for used PE mulch. Research studies have shown that soil-biodegradable plastic mulch (BDM) is comparable to PE mulch in terms of performance, soil health, and overall economics and is preferred from an environmental perspective, but the adoption of BDM by producers is still low. Previous research has shown that the primary barriers to BDM adoption are insufficient knowledge about BDM, high purchase cost, and unpredictable breakdown of BDM in the soil. The high purchase cost of BDM compared with PE mulch is offset by the costs for PE mulch removal, transport, and disposal fees. This project was conducted to develop BDM training materials, to educate and assess BDM knowledge gained by extension personnel and other agricultural professionals through trainings and webinars, and to educate producers about BDM through hands-on experience. Thirty-six research and extension publication outputs from two previous US Department of Agriculture Specialty Crop Research Initiative BDM projects were reviewed and transcribed into 45 new extension publications that included 11 slide presentations, 5 lecture slides, 10 fact sheets, and 3 videos. All the training materials are posted on a public university website. Professional development trainings were conducted at local, regional, national, and international levels to provide agricultural professionals the current, science-based information on BDM and resources for information. Survey results showed that at a local level, the greatest change of knowledge among participants was observed for “BDM use in organic production” (60%), and the lowest reported change of knowledge was observed for “limitations to PE mulch disposal” (19%). At a regional level, out of 58 participants, 23% to 35% of participants learned “a lot” and 35% to 51% learned “some new information” regarding BDM from the webinar. At the national level, out of 30 participants, 48% responded that they learned “a lot” and another 48% learned “some new information” on BDM from the training. Growers were trained about BDM via field days and on-farm demonstrations where five strawberry (Fragaria ×ananassa) growers volunteered to participate in BDM trials. The participant growers observed no difference in weed control and fruit yield between the PE mulch and the BDM. Growers expressed concerns about slow biodegradation of BDM after soil incorporation, potential impacts on soil biological activity, food safety concerns with BDM fragments and that BDM is not currently permitted for use in organic production.

Detection of bacterial pathogen on corn plants and test the potential of endophytic microbes to controlling stewart wilt disease in vitro

The use of synthetic pesticides to increase maize production sustainably contributes to increasing the development of pathogens and tends to be less effective in environmental conditions that support pathogens. In addition, the emergence of environmental pollution due to the use of chemicals causes the need for environmentally-friendly control technologies. Endophytic microbes are biological agents that can be used to plant disease control that is environmentally friendly and practical in their application. The study aimed to detect pathogenic bacteria that cause wilt and blight in maize and then examine the potential of several endophytic microbial isolates in controlling Stewart wilt pathogens in maize in vitro. The research was carried out from February to July 2021 at the Cereal Crop Research Institute Laboratory in Maros for morphological identification and microbial potential testing, while serological tests were carried out at the Makassar Plant Quarantine Laboratory, South Sulawesi. The study began with detecting pathogenic bacteria serologically using the Enzyme-Linked Immunosorbent Assay (ELISA) method. The results showed that blight symptoms on corn isolated from the experimental garden of IP2TP Bajeng Gowa Regency PS-4 and PS-5 were detected as bacteria Pantoea stewartii subsp. stewartii. The antagonistic test of endophytic bacterial isolates I.A1, II.D1, III.A2, IV.B2, and endophytic fungi isolates AC-1, AC-3, and DC-5 was able to suppress the growth of pathogenic bacteria isolates PS-4 and PS-5 The growth suppression of pathogenic bacteria was observed by forming inhibitory zones of antibiosis compounds. Pathogenic bacteria Pantoea stewartii subsp. stewartii can be controlled using endophytic microbes.

Preplant Application of Allyl Isothiocyanate Controls Weeds and Pathogens in Eastern North Carolina Strawberry (Fragaria ×ananassa cv. Camarosa) with and without Addition of Soil-applied Steam

Allyl isothiocyanate (AITC) is a colorless aliphatic oil that naturally occurs in many plants of the cabbage and mustard family (Brassicaceae). It has antimicrobial activity and is used as pesticide for a variety of applications. However, AITC as a soil disinfectant has exhibited inconsistent weed and pathogen control, mainly because of its higher viscosity and low vapor pressure (5 mmHg at 25 °C). Steam, however, effectively controls soil-borne pathogens if soil temperatures of 65 °C or more are reached for a minimum duration of 30 minutes. We hypothesized that steam applications targeting lower temperatures, when combined with soil-injected AITC, will provide sufficient weed and pathogen control. We further hypothesized that the combination of AITC and steam will lead to higher strawberry yields compared with either of the components on their own. Two strawberry (Fragaria ×ananassa cv. Camarosa) trials were conducted during two consecutive seasons (2020–21 and 2021–22). The trials were conducted at the Central Crops Research Station in Clayton, NC, USA, and the Horticulture Research Station in Castle Hayne, NC, USA. Eight treatments and a nontreated control were established in a randomized complete block design (four replicates each). The treatments were Pic-Clor 60, AITC, AITC followed by 60 minutes of steam injection, AITC followed by 30 minutes of steam injection, AITC followed by 10 minutes of steam injection, 60 minutes of steam injection, 30 minutes of steam injection, and 10 minutes of steam injection. Soilborne pathogen control efficacy was assessed using wet Pythium sp. plating assays. Weed control was assessed through weed seed/tuber germination assays. Our results showed that combining ATIC with steam did not reduce weed or pathogen levels or improve yield when compared with AITC alone or Pic-Clor 60. Moreover, treatment comprising steam alone did not provide sufficient control. However, AITC alone controlled weeds and pathogens as effectively as Pic-Clor 60 during both years and both locations of the study. These results showed that AITC alone could be a potential alternative soil disinfectant for Eastern North Carolina strawberry production.

Transplanting of 24 days and 25 days old seedlings were done on 20th June in 2021 kharif and 23th June in 2022 kharif, respectively, on the same day of dibbling in the main field at 100 cm × 100 cm ,120 cm × 120 cm square geometry and 150 cm × 60 cm. Nutrient management treatments were imposed one week after sowing. Result: Among the planting methods higher nodule number and nitrogenase activity with transplanting compared to dibbling. 120 cm × 120 cm found higher nodule number plant-1 and nitrogenase activity but biological nitrogen fixation was higher with 100 cm × 100 cm ha-1 basis. With respect on nutrient management practices, control performed well in terms of higher nitrogenase activity and biological nitrogen fixation and on par with integrated approach of 100% soil test based NPK + vermicompost + PSB + seed treatment with Rhizobium. So, with transplanting method of establishment, 100 ´ 100 cm square plant geometry and 100% soil test based NPK + vermicompost + PSB + seed treatment with Rhizobium was recommended agronomic practices for hybrid pigeonpea.
