Low productivity of chickpea in Bangladesh is obtained due to different disease incidence and seed treatment by fungicides can minimize the disease severity. A laboratory and field experiment was conducted at Regional Agricultural Research Station, Jashore, Bangladesh to evaluate the effect of some seed treating fungicidal groups on germination, soil-borne as well as seed-borne disease incidence and yield contributing characters of chickpea (BARI Chola-10). In laboratory the experiment was conducted in CR design and in field condition the experiment was conducted in RCB design with three replications in both conditions. Five fungicides namely Provax 200 WP (Carboxin +Thiram), Secure 600 WG (Fenamidone + Mancozeb), Rovral 50 WP (Iprodione), Bavistin 50 WP (Carbendazim), Captan 50 WP along with control was maintained as experimental treatment. The fungicidal group treatments showed significant variation among the parameters except days to mature. The highest germination (92%), plumule length (31.22 mm), radicle length (12.26 mm), Vigor index (4015.5), Percent disease reduction over control (84%), plant height (63.67 cm), plants m- 2 (31), pods plant-1 (81), grain yield (2062.7 kg ha-1) and the lowest days to 50 % flowering (65), disease incidence (3.33%) was found when seeds were treated with fungicide Provax 200 WP (Carboxin +Thiram). To reduce the soil-borne as well as seed-borne disease incidence and to increase grain yield of chickpea, seed treatment with provax 200 WP should be followed.

A trial was conducted during 2015-16 to 2017-18 at the Regional Agricultural Research Station (RARS) of Bangladesh Agricultural Research Institute (BARI), Jashore to select some tolerant varieties against wheat blast. Fourteen varieties including eight old varieties (Sonalika, Kanchan, Sourav, Gourab, Shatabdi, Sufi, Bijoy, Prodip) and six newly released varieties (BARI Gom 25, BARI Gom 26, BARI Gom 27, BARI Gom 28, BARI Gom 29 and BARI Gom 30) were evaluated. The experiments were non-replicated and were planted in two sowing dates, at optimum (mid November) and late (mid December) conditions. Three irrigations were applied, at crown root initiation (CRI), heading and grain filling stages. Plants of border rows were inoculated by Magnaporthe oryzae triticum (MoT) spores (104 conidia ml-1) for infection once per week from three weeks after sowing until primary infection was observed. The significantly higher grain yield was observed in 2016-17 (3505 kg ha-1) which was similar to 2017-18 (3448 kg ha-1) and the lowest was in 2015-16 (1680 kg ha-1). The higher grain yield was obtained due to the higher grains spike-1 (45 no.) and 1000 grain weight (36.6 g) and lower blast disease incidence (% blast index 18.1%). In all three years, there was heavy infection of wheat blast in late sowing condition (% blast index 40.7) compared to the optimum sowing condition (% blast index 1.4), resulting in very poor crop yield (1696 kg ha-1). Among the varieties, the variety Gourab produced the highest yield (3395 kg ha-1) which was similar to the newly released variety BARI Gom 28 (3196 kg ha-1) and BARI Gom 30 (3134 kg ha-1). In case of blast disease severity, old varieties were less infested with some exception in Sonalika and Kanchan. On the other hand, BARI Gom 25 and BARI Gom 26 were more susceptible (% blast index 35.3-36.5) to wheat blast compared to BARI Gom 28 and BARI Gom 30 (% blast index 20.2-22.5).

Background: Bio-fortification, the process of integrating nutrients into food crops, provides a sustainable and economic way of increasing the density of micronutrients in important staple crops. Agronomic bio-fortification is the easiest, practicable and fastest way for bio-fortification of pulse grains with Fe, Zn, or other desirable micronutrients. Increasing micronutrient rich foods and improving dietary diversity will substantially reduce micronutrient disorders.Methods: A field experiment was conducted during the post rainy seasons of 2015, 2016 and 2017 at Zonal Agricultural Research Station, Kalaburagi, University of Agricultural Sciences, Raichur (Karnataka) to know the effect of soil and foliar fertilization of Zn and Fe on chickpea genotypes. Two genotypes (Annigeri 1 and JG 11) and six fertilization treatments (Control, 0.5% Zn, 0.1% Fe, Zn + Fe, seed treatment with 2 g Zn kg-1 seeds and soil application of Zn) were tested in medium black soils in split plot design with three replications.Result: The pooled data of three seasons indicated that the genotype JG 11, performed better than Annigeri 1 in terms of seed yield (1309 kgha-1), net returns (₹ 31634ha-1) and B: C ratio (2.52). On biofortification of Zn and Fe, foliar fertilization of Zn @ 0.5% + Fe @ 0.1% at flowering stage recorded significantly higher grain yield (1321 kgha-1), net returns (₹ 31179ha-1) and B: C ratio (2.44) over rest of the treatments. Further, foliar fertilization of Zn + Fe had significant influence on nutrient concentration (Zn and Fe) in chickpea grains. Thus, it could be concluded that combined biofortification of Zn + Fe to chickpea crop could be the viable agronomic intervention for getting higher productivity and nutritional security.

A two-year field experiment was conducted at Regional Agricultural Research Station, Jessore during the rabi seasons of 2002-2003 and 2003-2004 to find out the level of disease incidence under different levels of irrigation and fungicide spray on the bulb yield of onion. Four irrigation levels: no irrigation (I1), irrigation at 10 days interval (I2), 20 days interval (I3), and 30 days interval (14) with 4 spray schedules: no spray (F1), one spray at 40 days after transplanting (DAT) (F2), two sprays each at 40 and 55 DAT (F3) and three sprays each at 40, 55, and 70 DAT (F4) were used. Yield and yield attributes varied significantly (p = 0.05) between sprayed and unsprayed, and irrigated and non-irrigated treatments, respectively. Higher yields were obtained with the higher frequencies of irrigation and spray. Application of fungicide reduced the disease severity significantly, while irrigation had no significant effect on disease infection. But there was a decreasing trend of the disease severity with increasing irrigation frequency. The highest bulb yield of onion (12.45 t/ha) was obtained with a total water use of 245 mm in six applications including an effective rainfall of 16 mm and three sprays. The disease severity between sprayed and unsprayed plots ranged from 1.33 to 3.16 for I1, 1.08 to 2.33 for I2 1.16 to 2.83 for I3, and 1.16 to 3.00 for I4, respectively.

Shallot (Allium cepaL. var.ascalonicum) is the most traditional vegetable crop in Ethiopia. Shallot is susceptible to a number of diseases that reduce yield and quality, among which fusarium basal rot (FBR) caused byFusarium oxysporumf.sp.cepae (Foc)is one of the most important yield limiting factors in Ethiopia. The present study was designed to evaluate the effectiveness ofBrassicacrops for the management of shallot FBR on shallot. The experiments were carried out at Debre Zeit Agricultural Research Center using cabbage (Brassica oleracea), garden cress (Lepidium sativum), Ethiopia mustard (B. carinata), and rapeseed (B. napus). The evaluations were done underin vitroand greenhouse conditions. Underin vitrotest condition it was confirmed that extracts of Ethiopian mustard and rapeseed showed higher inhibition on the growth ofFocpathogen compared to control. Data on seedling emergence, plant height, plant stand, disease incidence, severity, cull bulbs, and bulb weight were collected in greenhouse experiment. The green manure amendments of rapeseed and Ethiopian mustard significantly reduced disease incidence by 21% and 30% and disease severity by 23% and 29%, respectively. However the plant emergency was not significantly different among treatments in greenhouse test. These results indicated that Ethiopian mustard and rapeseed crops have potential as green manure for the management of FBR disease of shallot crop.

Microplot Yield Trial (MPYT) were conducted during the year 2013. Total 20 genotypes were includedin CVT experiment of both years. Although the difference in grain yield due to genotypes was not found significant during the year 2012, NL1144 recorded the highest grain yield (4309 kg/ha) followed by NL 1140 (4295 kg/ha) and NL 1147 (4165 kg/ha) respectively. But in the year2013, NL 1097 produced the highest grain yield (4641 kg/ha) followed by NL 1135 (4383 kg/ha) and NL 1164 (4283 kg/ha) respectively.Statistically, the difference in grain yield due to genotypes was not found significant in the year 2013. Combined analysis over years was alsocarried out. Out of 20, only 10 genotypes were included in the CVT experiment, which were found similar in both years. Genotypes NL 1097(4079 kg/ha), NL 1140 (3814 kg/ha) and NL 1093 (3773 kg/ha) were found high yielding genotypes for river basin agro-environment of farwestern hills. Statistically, effect of year in tested characters was found significant whereas treatment effect was observed non-significant.Similarly, 20 genotypes of wheat were included in AVT of wheat during the year 2012 and 2013. Out of the genotypes included in AVT duringthe year 2012, KISKADEE No.1recorded the highest grain yield (3824 kg/ha) followed by CHEWINK No. 1 (3643 kg/ha) and WK 2120 (3583kg/ha). Statistically all the tested characters except grain yield were found significantly different due to genotypes.

A field experiment was carried out at El-Kod Agricultural Research Station, Abyan Delta, Abyan Governorate during the seasons 2014 and 2015 in soil sandy silt to assess four levels of nitrogen fertilizers (0, 55, 110 and 165 kg N/ha) utilizing urea fertilizer (46% N) on some crop characteristics and efficiency of nitrogen application on two local cultivars of sorghum (Sorghum bicolor L. Moench). Split plot design was applied in four replicates. Fertilizer levels were distributed in main plots whereas, the cultivars in subplots. The results revealed significant differences between cultivars Benny and Saif in all characteristics during the two seasons. Cultivar Benny was significantly superior to cultivar Saif in all crop characteristics, except the length of spike which was significantly superior in Saif cultivar compared to cultivar Benny in both seasons. The increase in nitrogen level led to significant increase in all parameters of crop growth under study in both seasons, where the highest dose of nitrogen (165 kg N/ha) gave highest grain yield (3013 and 3201 kg/ha) in both seasons respectively, while the efficiency of nitrogen utilization declined with increased level of nitrogen application and highest value in nitrogen efficiency (12.78 kg grain/kg N). The interaction between cultivars and nitrogen fertilizer showed significant differences in terms of all studied parameters during both seasons. The cultivar Benny responded to high level of nitrogen (165 kg N/ha) and gave high grain yield (3640 and 3305 kg/ha) in both seasons respectively. The results yielded significant effect for efficiency of nitrogen application on grain yield between the cultivars, the levels of fertilizers and their interaction in the first season whereas, no significant differences were detected in the second season.

A rust fungus was observed on smooth brome grass (Bromus inermis Leyss.) leaves growing in the fields of the University of Wisconsin (UW) Agricultural Research Station at Arlington, WI. The population (WPc-95A) was classified as Puccinia coronata Corda. Reports of P. coronata on B. inermis are rare, so a study of the pathogen host range, alternate host, and morphology of urediniospores and teliospores was undertaken. Fourteen grass species representing 10 genera were inoculated with P. coronata WPc-95A, which was maintained with repeated inoculations on B. inermis cv. PL-BDR1. Seventy-two 30-day-old seedlings of B. inermis were inoculated with urediniospores of the fungus. Infection type, pustule density, and disease incidence were recorded 15 days after inoculation. The same grass cultivars were also inoculated with aecio-spores collected from Rhamnus cathartica L. located on the UW campus. To test for host specificity, urediniospores produced on aeciospore-susceptible grass species were used to reinoculate plants of B. inermis and the host species from which the urediniospores were derived. B. inermis, B. riparius Rehm., Festuca pratensis Huds., and Lolium perenne L. were susceptible to P. coronata WPc-95A. The two Bromus spp. had the highest disease incidence. R. cathartica was found to be an alternate host of P. coronata WPc-95A, as it is for P. coronata isolates found on F. pratensis. However, cross-inoculations with urediniospores from R. cathartica-derived aeciospore infections indicated that only urediniospores of B. inermis origin were capable of infecting B. inermis. Thus, P. coronata WPc-95A appears to belong to a forma speciales previously undescribed in North America.
