ABSTRACT Peanuts (Arachis hypogaea L.) have been one of the most profitable crops in the southeastern coastal plains but with increasing cost of production, growers continually seek to lower inputs and enhance overall profitability of their farms. Peanut cultivars with high yield potential and disease resistance along with drought tolerance are therefore obvious choices for sustainable production. Runner-type peanut cultivars were evaluated for pod yield and grade for three yr. Five peanut cultivars were evaluated in 2014 and 2015 and six cultivars in 2016 at the North Florida Research and Education Center, University of Florida, Quincy, FL. Cultivar performance was observed at different planting dates, four in 2014 and three in 2015 and 2016, to evaluate impacts of early, mid, and late planting with and without irrigation. Georgia cultivar GA-12Y consistently yielded greater than the other varieties in all yr of the study. Average pod yield for GA-12Y was 5980 kg/ha for three yr compared to 5140 kg/ha, 4730 kg/ha, 4890 kg/ha for GA-06G, FloRun 107, and TUFRunner 511, respectively. Florida cultivar TUFRunner 297 yielded greater (5300 kg/ha) than the rest of Florida cultivars irrespective of the planting date and had higher proportion of total sound mature kernels (TSMK) compared to GA-12Y in two of the three yr. Planting date had no impact on peanut pod yield in 2014 and 2015. However, peanut yield for all the cultivars was higher at later planting dates in 2016. The advantage of irrigation was not always consistent in all the yr, likely due to high rainfall during the study yr, removing that advantage.

Abstract Peanut (Arachis hypogaea L.) growers must balance complex interactions among cultivars, planting dates, environmental and physiological stresses during the growing season, and weather conditions at harvest when determining when to dig peanut. Ten field experiments were conducted in North Carolina from 1994 through 1996 to determine the influence of digging date on pod yield and gross return of virginia-type peanut. Beginning in mid- to late September, the cultivars NC 9, NC 10C, NCV-11, VA-C 92R, AgraTech (AT) VC-1, and NC 12C were dug on four dates approximately 7 d apart. Considerable variation in pod yield and gross return was noted among cultivars and experiments. Delaying digging increased pod yield and gross return in some but not all experiments. Greater variation in pod yield and gross return was observed for NC 10C than for AT VC-1 when compared across digging dates. Pod yield and gross return for NC9, NC V-11, VA-C 92R, and NC 12C were intermediate between NC 10C and AT VC-1. Of the cultivars evaluated, yield and gross return of AT VC-1 were the most stable over digging dates. These data suggest that growers should evaluate maturity of peanut in individual fields for each cultivar when determining when to dig. These data also suggest that factors other than maturity impact pod yield and gross return.

ABSTRACT Peanut (Arachis hypogaea L.) is an important crop in the Virginia-Carolina (VC) region. Virginia-type cultivars are preferred vs. other peanut types because of the in-shell and gourmet markets that evolved in the VC region around this peanut type. Reduced federal support coupled with increased production costs for the virginia-type peanut vs. other peanut types and recently higher fuel and pesticide prices are good reasons for farmers to consider growing other peanut types than virginia-type in the VC region. Earlier research suggested that runner-type peanut can provide yield, gross value, and economic return similar with virginia-type when grown in the VC region. However, direct comparison of runner and virginia-type cultivars needs to be updated as new cultivars become available. In this study we compared four runner-types with five virginia-type cultivars for plant development, disease incidence, pod yield, pod brightness, grade factors, and gross value in 2009 and 2010. In agreement with earlier findings, the results show that runner-types can provide similar gross returns with virginia-type peanut cultivars when grown in the northern VC region. Florida 07 runner and Bailey virginia-type, currently the most popular cultivars in the VC region, had high yields and gross values in both years. However, Florida 07 and other runners matured later and pods were less bright when compared with the virginia-types. Therefore, growing runners in the northern VC region may be challenging due shorter seasons and reduced pod brightness if peanut is used for in-shell markets.

The release of high-oleic, United States runner and virginia market type peanut (Arachis hypogaea L.) cultivars has been steadily increasing during the past several years. Two planting dates were utilized for disease evaluation and agronomic performance among these newer high-oleic cultivars. The first planting date test was in mid-April to allow for increased incidence of spotted wilt disease caused by Tomato spotted wilt virus (TSWV). The second planting date test was in mid-May to allow for less TSWV and provide more of an optimum time by comparison. Significant differences (P ≤ 0.05) were found within each of the three (3-year) averages among cultivars for TSWV and total disease (TD) incidence, pod yield, and dollar values. Among the virginia-types, Georgia Hi-O/L, Georgia-05E, and Georgia-08V, and runner-types, Georgia-02C and Georgia-09B, consistently had the lowest TSWV and TD incidence and the highest pod yield and dollar values in both the mid-April and mid-May planting date tests. No significant differences were found between the mid-April and the mid-May planting dates when averaged across this 5-year study for TSWV and TD incidence, pod yield, and dollar values. This suggests that the high-level of TSWV-resistance among these newer high-oleic cultivars should have a greater influence than planting dates on agronomic performance.

During 2012, 2015, and 2018 a set of 18 peanut (Arachis hypogaea L.) genotypes (some common and some different) were used to evaluate the effect of planting dates (April, May, and June) on leaf spot disease and pod yield. Within each year, the same genotypes were grown during the three planting dates at the Gibbs Farm near the University of Georgia, Coastal Plain Experiment Station, Tifton, GA using a randomized complete block design with five replications without fungicides or insecticides but with irrigation. Each year, significant differences (P≤0.05) were found among the genotypes within each of these three planting dates for leaf spot disease ratings (0-9 scale) and pod yields. ‘Georganic’ in 2012 and 2015; and GA 132705, ‘Georgia-19HP’, and ‘Georgia-14N’ in 2018 had among the lowest leaf spot ratings. ‘Georgia-12Y’ had the highest average pod yield for each year of the three years. Each year during this study, the April planting date had the lowest, and the June planting date had the highest leaf spot disease ratings. Percent coefficient of variation (CV) was consistently lower at the June planting date which suggest the least variability among the peanut genotypes. In the overall average of genotypes, the April planting date resulted in the highest pod yield and the June planting date had the lowest average pod yield. In summary, April planting dates resulted in the highest pod yields, and the lowest leaf spot ratings across each of the three years.

High Yield Potential

The experiment was conducted at the Agronomy Field Bangladesh Agricultural University, Bangladesh to investigate the effect of planting dates on the performance of high yield potential varies of rice in Boro season. The experiment consisted of five dates of transplanting viz. 10 and 25 December 2015, 10 and 25 January and 10 February 2016: four high yield potential varieties viz. hybrid rice Sonar Bangla-1, Jagoran, BRRI Dhan-29 and BINA Dhan-6. Results indicated that there was a significant effect of date of transplanting on yield of potential varieties of rice in Boro season. It was observed that plant height, panicle length, grain yield, straw yield, number of tillers per hill-1 gradually increased up to 10 January. After 10 January transplanting yield reduced. The highest grain yield 6.41 t ha-1 was observed in hybrid rice Sonar Bangla-1. The result revealed that Sonar Bangla-1 emerged as the best variety in Boro season regarding grain and straw yields among the varieties studied and it should preferably be transplanted between 25 December to 10 January to obtain appreciable better yield.

Abstract Field studies were conducted over a three year period to examine the sensitivity of four peanut (Arachis hypogaea L.) cultivars (Florunner, Sunrunner, Southern runner, and NC 7) to foliar applications of paraquat (1, 1′-dimethyl-4, 4′-bipyridinium ion). Treatments included an untreated control and four herbicide treatments: paraquat applied alone at 0.14 and 0.28 kg/ha, or tank mixed with alachlor [2-chloro-N-(2, 6-diethylphenyl)-N-(methoxymethyl)acetamide] at 4.40 kg/ha. Weeds were hand-removed so that only herbicidal treatments were variables. Paraquat phytotoxicity did not differ between cultivars. No cultivar evaluated was abnormally sensitive nor tolerant to any paraquat-containing treatment. Laboratory studies utilizing radio labelled paraquat revealed that foliar absorption and translocation of paraquat did not vary between peanut cultivars. Yield differences were attributed to differences in yield potential between cultivars.

Moisture Deficit

Two experiments were conducted to determine the growing degree-day (D°) requirements of annual B. campestris and B. napus cultivars, and to evaluate their use in planning crop development strategies to avoid frost and moisture deficit at three locations. In the first experiment, base temperatures and D° requirements were calculated for four phases from planting to grain-filling, on the basis of linear temperature-development rate responses measured in the field at Tamworth, N.S.W. The phenological pattern of each species was predicted for several planting dates at locations representing the north-west slopes, northern tablelands and an intermediate region, by using long-term mean daily temperatures and calculated Do requirements. From these predictions and long-term mean daily rainfall and pan evaporation rates, the available soil moisture depletion was estimated for each planting date. For each location, planting date strategies for both species were evaluated for avoidance of frost and moisture deficit. The predicted optimum planting dates for B. napus and B. campestris were, respectively, 20 June and 5 August for the north-west slopes, 20 August and 1 October for the northern tablelands, and 30 June and 18 August for the intermediate region. In the second experiment, the influence of planting date on the grain yield of B. campestris and B. napus was studied in several seasons at each of the locations studied in the first experiment. The planting date that gave the highest yield varied between species and locations. B. campestris was favoured by later dates than B. napus. For both species these dates were earliest on the north-west slopes and latest on the northern tablelands. Yields of B. napus were higher than those of B. campestris at all locations when each species was planted at a favourable time. Predicted optimum planting dates from experiment 1 are discussed in relation to the field results from experiment 2. _____________________ *Part I, Aust. J. Agric. Res., 29: 693 (1978).

The Impact

The impact of today’s optimal planting dates on sudden death syndrome (SDS) (caused by Fusarium virguliforme) development and soybean yield loss are not yet well understood. Field trials established in Hancock, Wisconsin during 2013 and 2014 investigated interactions between planting date and cultivar on SDS development and soybean yield. In 2013, disease index (DX) levels differed among cultivars, but results showed no difference between the 6 May and 24 May planting dates. Significantly lower DX levels were observed for the 17 June date. Greatest yields were found in the 6 May planting date, and yield losses were 720 (17%), 770 (20%), and 400 kg ha−1 (12%) for the 6 May, 24 May, 17 and June planting dates, respectively. In 2014, cultivars again differed for DX, but results showed highest DX levels in the 5 May planting date, with little disease observed in the 22 May and 11 June dates. Yield losses were 400 (12%) and 270 kg ha−1 (9%) for the 5 May and 22 May dates, respectively, but no difference was found in the 11 June date. Despite the most symptom development, these results suggest early May planting coupled with appropriate cultivar selection provides maximum yield potential and profitability in Wisconsin.

ABSTRACT Peanut (Arachis hypogaea L.) peg strength and associated pod yield and digging loss were documented for nine cultivars and two breeding genotypes across three harvest dates (early, mid, and late season) at two Southwest Georgia locations during 2010 and 2011. Cultivars selected were Georgia Green, Georgia Greener, Georgia-02C, Georgia-06G, Georgia-07W, Georgia-09B, Georgia-10T, Florida-07, Tifguard, and advanced breeding lines EXP27-1516 and TifGP-2. Prior to digging, a minimum of three peanut plants from each plot were selected and excess stems and leaves were removed with scissors leaving individual peanut pegs and pods with about 5-cm of stem. Each peanut pod was placed in a “U” shaped metal bracket attached to an electronic force gauge and the stem was pulled manually until the pod detached. After digging and combining, a tractor-mounted scavenger machine was used to collect pods remaining in the soil. Peg strength was greater at Dawson (6.14 N) compared to Tifton (5.28 N) in 2010 but were similar in 2011 (4.51 and 4.39 N, respectively). Dawson had consistently higher yields (5326 kg/ha) and lower pod loss (562 kg/ha) compared with Tifton (3803 kg/ha and 936 kg/ha, respectively). Peanut cultivars with greater peg strength across locations were Georgia-06G, Florida-07, and Georiga-02C. Cultivar Georiga-06G showed the greatest yield across locations and years. Other cultivars may have had stronger peg strength, greater pod yield, or lower pod loss but none were more consistent than these three cultivars across years, locations, and harvest dates.
