This study was conducted to determine the residual effects of chicken manure applications on nutrients in leaves and bulbs of second crop onion that grown after lettuce in greenhouse conditions. In the study, residual effects of chicken manure in 4 different doses (control, 20 t ha-1, 40 t ha-1, 60 t ha-1) and chemical fertilizers applied in the recommended amounts are investigated. Three onion varieties, called Burgaz, Snow white, Champion, were used. In the study, the lowest nutrient uptake was observed in control. However, the highest mineral content in leaves and bulbs were determined in the plots, that on average 40 t ha-1 chicken manure was applied to. In terms of leaf nutrient content, when the varieties were compared to each other, Ca, Mg, and Cu contents were found to be the highest in the Burgaz variety. Phosphorus, Zn, Mn contents were analyzed to be the highest in Snow white while N values determined maximum in Champion. The Champion variety contained higher nutrient values in bulbs.

In this study, it was aimed to determine the effects of different sowing times and different varieties of German chamomilla (Matricaria recutita L.) on agronomic and technological characteristics. The study was conducted in experimental fields of the Department of Field Crops, Faculty of Agriculture in Adnan Menderes University. Two different tetraploid Matricaria recutita L. (Bodegold and Zloty Lan) cultivars were used for this study. Zloty Lan was provided by Germany and Bodegold was provided from Atatürk Central Horticultural Research Institute. The trial was conducted according to a split plot experimental design with 4 block. Factors consist of 5 sowing times as main plots (1 October, 15 October, 1 November, 15 November, 1 December) and 2 genotypes as subplots (Bodegold and Zloty Lan). The effect of sowing times and genotypes was found statistically significant on fresh flower yield. The highest flower yield was found 61.61 kg da-1 . The average values for plant height ranged from 45.43 to 55.20 cm, flower diameter ranged from 25.24 to 27.53 mm, biomass ranged from 130 to 332.3 kg da-1, fresh flower yield ranged from 19.74 to 61.61 kg da-1 , drug herb ranged from 35.5 to 73.5 kg da-1 , drug flower ranged from 7.4 to 13.3 kg da-1 , essential oil content ranged from 0.025% to 0.083% and essential oil yield ranged from 0.020 to 0.090 l da-1. The primary constituents of essential oil have been discovered as bisabolol oxide a and bisabolene oxide.

This study investigated the effects of Potato Golden Cyst Nematode (Globodera rostochiensis) on plant development and tuber yield in naturally infested fields with and without nematicides. The study was arranged in a randomized block design in the Alay district of Niğde province in 2021. In the study 4 varieties (PAE 13-08-07 clone, Ünlenen, Leventbey, Muratbey) developed by Niğde Potato Research Institute and two controls (Desiree and Bettina) were used. 50% emergence time, 50% flowering time, number of stems per plant, plant height, tuber maturation time, number of large tubers in total tuber and tuber yield per hectare were examined in potato varieties. No difference was detected in 50% emergence time, number of stems per plant and 50% flowering time in potato varieties in the nematicide-applied area and the nematode-infested area. Varieties were affected by nematicide application at varying rates in terms of plant height and tuber maturation time. The most significant increase in tuber size and tuber weight was observed as a result of nematicide application in the field infested with Potato Golden Cyst nematode.

This study was conducted to investigate the relationship between the recent increase in the frequency of drought conditions and Root-Crown Rot (Fusarium pseudograminearum, Fusarium culmorum) in rainfed wheat growing areas of Central Anatolia. In 2018, the experiment was established in the greenhouse of Konya Bahri Dağdaş International Agricultural Research Institute using 25 registered wheat varieties in a randomised block split-plot experimental design with 4 replications. Irrigation levels (100% field capacity and 50% field capacity) were designed as main plots, inoculation (+ and -) as subplots and varieties as sub-subplots. In the study, the response of the cultivars to inoculation under artificial drought conditions was evaluated by measuring Crown Score (CR), Lesion Length (LL), Number of Diseased Leaves from outside to inside (NDL) and Plant Height (PH) from five plants in each pot. Statistically, the differences between inoculation, irrigation, NDL and LL were found to be significant at P<0.0001 level, while the differences between varieties were found to be significant at P<0.001 level for the CR parameter. On the other hand, when the interactions were evaluated for the NDL parameter, the differences were found to be significant at P<0.0001 level for all three interactions of cultivar*inoculation, cultivar*irrigation and cultivar*inoculation*irrigation. When the effect of reduced water application intended to be used in resistance breeding was evaluated for 25 different varieties under Fusarium culmorum inoculation, there was an increase in CR from 41,7% (Gerek-79) to 487,5% (Altay-2000), NDL from 7,14% (Kirgiz-95) to 200% (Alpu-2001), LL from -36,84% (Karahan-99) to 283,33% (Altay-2000) and in PH reduction from 12,41% (Seval) to 32,22% (Kirgiz-95). The results showed that drought-stressed plants were already weakened and therefore more easily and severely infected by pathogens. According to these results, it has been determined that it is very important for the region to obtain resistance to drought and crown rot diseases, which have such an obvious relationship, in breeding studies.

Forty seed sample of wheat (Triticum aestivum) were collected from four locations viz. Chitwan, Kaski, Banke and Lalitpur and tested by blotter method at laboratory during 2013 for determining fungal pathogens associated with wheat seeds in Nepal. Eighteen species representing thirteen genera of fungi were recovered from the seed. Alternaria alternata and Bipolaris sorokiniana were predominant in all the varieties/genotypes from all the locations, where B. sorokiniana was strongly pathogenic in wheat crop. Percentage frequency and type of fungi detected varied with variety and locations. Bipolaris sorokiniana was highest (64.40%) in Banke than remaining three locations. Seeds of Chitwan had lowest percentage (5.50%) of seed infection as compared to other locations. Relative abundance of Alternaria alternata (55.10%) was highest as it was the most prevalent component of seed borne mycoflora, followed by Bipolaris sorokiniana (34.69%) and Cladosporium herbarum (7.19%). Differences in quantity of precipitation and relative humidity might be the possible reason for variation in frequency and type of fungi detected in wheat seeds of four locations.
