Eight cotton cultivars, with and without aldicarb treatment, were evaluated for their effect on the severity of the root-knot nematode-Fusarium wilt disease complex in cotton. A randomized complete block design with a split-plot arrangement of treatments was used with cotton cultivars as the main plots and nematicide treatments as the subplots. Results in 1994 and 1995 were similar. Yield of lint, boll weight, and wilt and root-gall ratings were different among cultivars and between nematicide treatments both years. Increased lint yield and boll weight, and reduced root-gall and wilt ratings were associated with application of aldicarb. Increased lint percentage was associated with application of aldicarb in 1994, but not in 1995. Fiber micronaire, elongation, uniformity, and strength were different among cultivars, but not between nematicide treatments. Fiber length (UHM; Upper-Half Mean) was different among cultivars and was higher in the aldicarb-treated plots in both years. Numbers of Meloidogyne incognita second stage juveniles and eggs extracted from soil samples were lower in the aldicarb-treated plots in July, but not at harvest, both years. Population densities of M. incognita were not different among cultivars, except the mid-season sample in 1995.

In this study, the effect of a Kenyan strain of Sweetpotato leaf curl virus (SPLCV) and its interactions with Sweetpotato feathery mottle virus (SPFMV) and Sweetpotato chlorotic stunt virus (SPCSV) on root yield was determined. Trials were performed during two seasons using varieties Kakamega and Ejumula and contrasting in their resistance to sweetpotato virus disease in a randomized complete block design with 16 treatments replicated three times. The treatments included plants graft inoculated with SPLCV, SPFMV, and SPCSV alone and in possible dual or triple combinations. Yield and yield-related parameters were evaluated at harvest. The results showed marked differences in the effect of SPLCV infection on the two varieties. Ejumula, which is highly susceptible to SPFMV and SPCSV, suffered no significant yield loss from SPLCV infection, whereas Kakamega, which is moderately resistant to SPFMV and SPCSV, suffered an average of 47% yield loss from SPLCV, despite only mild symptoms occurring in both varieties. These results highlight the variability in yield response to SPLCV between sweetpotato cultivars as well as a lack of correlation of SPLCV-related symptoms with yield reduction. In addition, they underline the lack of correlation between resistance to the RNA viruses SPCSV and SPFMV and the DNA virus SPLCV. [Formula: see text] Copyright © 2020 The Author(s).

Chickpea (Cicer arietinum) is one of the world’s major legume crops and suffers substantial damage from wilt disease caused by Fusarium oxysporum f. sp. ciceri( Padwick) with yield loss over 60 per cent. It is an important soil borne plant pathogen and is difficult to manage by application of chemical pesticides. Moreover, the chemical control is costly and leads to residual effect. A plethora of reports indictes the efforts made to reduce environmental effects and rationalize the use of pesticides and manage the pathogen more effectively through Integration of Disease Management (IDM). Application of soil amendments and specific bio-control agents also incorporated in IDM which has potential to suppress soil-borne pathogens through manipulation of the physicochemical and microbiological environment. Therefore, IDM approach for controlling chickpea Fusarium wilt might be a cost effective and eco-friendly approach.

This research was conducted in Pante Cermin, Padang Tiji Subdistrict, Pidie District. in March to August 2015, with the aim to know the use efficienci of Trichoderma sp on the growth of several types of Banana seedlings (Musa Paracica L.) This research using Randomized Block Design (RAK) factorial pattern with the factors studied is the type of banana and trichoderma dose . Both factors consist of 4 levels: Banana Barangan (J1), Ambon banana (J2), Banana King (J3) and Geupok banana (J4). While the dose of Tricoderma sp is: TO = 0 g / seeds T1 = 15 g / seeds T2 = 30 g / seedlings and T3 = 45 g / seedlings. So there are 16 treatment combinations and repeated 3 times, which resulted in 48 experimental units.To determine the influence of each treatment and its interaction on the growth of banana seedlings, the analysis of variance (Test F) and continued with the test of Beda Nyata Jujur (BNJ) at 5% level.The results showed that the growth of good banana seedlings among 4 species studied was shown by Barangan bananas, but not unlike bananas. However, trichoderma administration until the age of 4 months has not shown the growth and intensity of different attacks. So it should be extended the study period to 6 months. After 6 months of research there has been a difference in growth and intensity of attack, where the intensity of the greatest attack is shown by T0 (without trichoderma). Medium intensity of smallest attack is shown by T3 (Dose trichoderma sp 45 gr / banana seedlings). The type of banana does not affect the growth and intensity of fusarium wilt attack. and the interaction of these two factors had no significant effect on the growth of banana seedlings and the intensity of Fusarium wilt disease.

Chickpea (Cicer arietinum) is one of the world’s major legume crops and suffers substantial damage from wilt disease incited by Fusarium oxysporum f. sp. ciceri (Padwick) with yield loss over 60 per cent. The screening for new resistance chickpea genotypes against this disease is an alternative approach to avoid indiscriminate use of chemical pesticides. In this study 55 chickpea genotypes were screened against Fusarium wilt. Out of 55 chickpea genotypes studied, only one genotype was found to be resistant and 12 were found to be moderately resistance. Nineteen genotypes showed moderately susceptible. However, nineteen and four genotypes showed susceptible and highly susceptible reaction for wilt disease, respectively.

Traditional medicines have been used in both developed and developing countries for a long time, one of which is longevity spinach (Gynura procumbens). Its plants are one type of plant that is used by the community to treat various diseases with their flavonoid content. This plant produces various flavonoids, such as quercetin, which can be optimized by providing shade and increasing nitrogen nutrients by giving biochar and fertilizing. This study aimed to determine the effects of biochar, shade, and fertilizer on the growth and quercetin content of Gynura procumbens plants. This research was arranged in a randomized complete block design (RCBD) with two factors. The first factor was the administration of biochar at four doses, consisting of B0 (without biochar), B10 (biochar 10 tons/ha), B15 (biochar 15 tons/ha), and B20 (biochar 20 tons/ha). Meanwhile, the second factor was the intensity of the shade with three levels of treatment, namely, I0 (without shade), I50 (50%), and I70 (70%). The results showed that the addition of 15 ton/ha of biochar with 70% shade increased the quercetin content by 0.51%.

Influences of nitrogen (N) rate were evaluated on vegetable amaranth. Amaranthus tricolor, grown at uniform populations over two year. The main objective was to determine an optimum level of N fertilization for successful production in middle Georgia. In 1992 and 1993 accession `RRC 241' was planted in randomized complete block design on June 19 and 23, respectively. Four N rates, equally split were evaluated: 0, 45, 90, and 135 kg ha-1. First of the applications were 18 and 13 days post planting for 1992 and 1993, and again when plants were 5 weeks old. Plants were harvested 48 days after planting with green yield, leaf fresh weight. and stem fresh weight collected in both years and leaf area for 1993. In years 1992 and 1993 green yields were 5.3 and 6.5, 10.7 and 9.0. 13.2 and 12.1, and 13.5 and 14.0 Mg ha-1. respectively for the 0, 45, 90, and 135 rates. In both years vegetative components showed significant regression for all treatments. Vegetative response (R2) for green yield in 1992 and 1993 was quadratic (85%) and linear (73%), leaf fresh weight in both years was cubic (63% and 48%), while stem fresh weight response was linear (29%) and cubic (72%). During 1993 leaf area was linear (58%). Non-significance predominantly occurred between the two higher rates for each year and when combined. indicating that 90 kg N ha-1 should provide optimal production of amaranth for the middle Georgia region.

In Southern India, drought stress is a major constraint to chickpea production and yield stability. Drought tolerant index (DTI) that provides a measure of drought based on yield loss under drought condition in comparison to normal condition was used for screening drought-tolerant genotypes. This study was conducted to determine drought tolerant genotypes with high yield in stress and non-stress conditions utilising physiological traits. Thirty chickpea genotypes were tested in a randomized complete block design with three replications under rain fed and irrigated conditions at Regional Agricultural Research Station, Nandyal, Andhra Pradesh, India during rabi, 2018-2019. The analysis of variance carried out for yield and drought tolerant traits revealed highly significant differences among the genotypes for all characters under rain fed as well as irrigated conditions. NBeG 776, NBeG 779, NBeG 868, ICCV 181606, MH 13 and MH 14 are drought tolerant. NBeG 776, NBeG 779 and NBeG 868 are suitable under both rain fed and irrigated conditions with significantly higher yields over their respective means. ICCV 181606, MH 13 and MH 14 are suitable exclusively for rain fed condition with significantly superior yields over the mean.
