Seed Decay

Incidence of Phomopsis seed decay is frequently high and quality low in seed from early-maturing maturity group III and IV soybean cultivars planted in early to mid-April in the southern United States. Cultivars resistant to this disease have not been available until the recent release of germ plasm lines SS 93-6012 and SS 93-6181. Our objective was to determine the effects of planting dates with these lines and one Phomopsis seed decay-susceptible soybean cultivar, Asgrow 3834, on seed infection by Phomopsis spp. and on yield and the correlation between percentage of Asgrow 3834 infected with Phomopsis spp. and seed quality. Generally, yields averaged over years were significantly greater for mid-April than mid-June plantings, and yields of cultivars were similar within a planting date. Soybean lines SS 93-6012 and SS 93-6181 were highly resistant to Phomopsis seed decay compared with the susceptible cultivar, Asgrow 3834. There was a significant, negative correlation between germination of seed from mid-April plantings of Asgrow 3834 and percentage of these seed infected with Phomopsis spp. Moreover, there were significant correlations between fatty acid composition of Asgrow 3834 seed and the percentage of these seed infected with Phomopsis spp. This altered composition of fatty acids may be responsible for reduced quality of oil derived from seed infected with this fungus. Phomopsis seed decay-resistant soybean lines SS 93-6012 and SS 93-6181 should be useful in breeding programs focused on developing high-yielding cultivars resistant to this disease.

Developmental Responses

Numerous studies have quantified the developmental responses of wheat to vernalization, but its response compared to a weedy relative, jointed goatgrass, remains relatively unknown. Six paired jointed goatgrass collections gathered from Washington and Oregon fields, and winter and spring wheat, were grown in field studies to quantify yield and germination in response to vernalization. Monthly planting dates initiated in October and concluded in March were used to vary the vernalization durations for plants sown at three Oregon locations (Corvallis, Moro, and Pendleton) over two growing seasons. Minimum vernalization requirements to produce reproductive spikes were similar among plants of six jointed goatgrass collections. Jointed goatgrass collections grown at Corvallis required a minimum of 89 and 78 vernalization days (January 17, 2003 and January 22, 2004 sowing, respectively) to produce reproductive spikes, and plants grown at Moro required 60 vernalization days (March 3 and February 23) in both years, and 48 and 44 vernalization days (March 3 and February 24) were required by plants to produce spikes at Pendleton. Jointed goatgrass spikelet and winter wheat seed yield were positively influenced by vernalization days, experiment location, and year. The strength of the interactions among these main effects differed among jointed goatgrass collections and winter wheat. The effects of vernalization on jointed goatgrass yields and seed quality were more pronounced at Pendleton, OR, a location where jointed goatgrass has adapted, compared to Corvallis, OR, where it has not adapted. The minimum vernalization days required to produce germinable seed differed among jointed goatgrass collections, winter and spring wheat. There was not a selection of spring-adapted jointed goatgrass populations in the populations tested. Yet if spring temperatures are cool, minimum conditions for vernalization may be satisfied, and the benefits of planting spring crops to control jointed goatgrass would be reduced.

The Abundance and Diversity of Thrips (Thysanoptera: Thripidae) on Chili (Capsicum annuum L.) and Cayenne (Capsicum frutescens L.) in Bogor. This research aimed to study the abundance and diversity of thrips on chili pepper and cayenne pepper plants. Observation of thrips was conducted on chili pepper and cayenne pepper in fourteen sites in four different locations in Bogor that are: Dramaga, Cibungbulang, Tenjolaya, and Cisarua. Thrips were collected from leaves and flowers from 10 plant samples that had been selected randomly. The thrips were identified and the number of thrips were calculated. The abundance of adults, nymphs, and total of thrips on the flowers of chili pepper was 0.39, 0.01, and 0.40 thrips/flower respectively. Meanwhile, the abundance of adults, nymphs, and total of thrips on the flowers of cayenne pepper was 0.36, 0.02, and 0.38 thrips/flower respectively. The abundance of adults, nymphs, and total of thrips on the leaves of chili pepper was 0.68, 0.12, and 0.81 thrips/twiq respectively. Meanwhile, the abundance of adults, nymphs, and total of thrips on the leaves of cayenne pepper was 0.47, 0.14, and 0.61 thrips/twiq respectively. Four species of thrips were found infesting flowers of chili pepper and cayenne pepper i. e. Thrips parvispinus, T. hawaiiensis, Scirtothrips dorsalis, and Haplothrips gowdeyi.  Species of T. parvispinus, T. hawaiiensis, S. dorsalis belong to suborder of Terebrantia family Thripidae, meanwhile H. gowdeyi belongs to suborder Tubulifera family Phlaeothripidae. T. parvispinus is the most dominant species found infesting flowers and leaves of the chilli pepper and cayenne pepper were 71% and 56 %.

Weather Damage

To demonstrate a model to simulate the risk of weather damage of mungbean, application studies were undertaken using 27 years of climatic data collected at Katherine, Northern Territory, Australia. In terms of the risk of weather damage, the transition from high risk to low risk occurred after mid-February but before 20 March. High quality seed could be expected in 70% of seasons for a crop that matured after 20 March. For planting dates prior to 25 January, the chance of producing premium quality seed was enhanced to 40–70% of seasons by sowing a cultivar that matured 2 weeks later and by harvesting promptly (4 days after maturity). There was no benefit from later maturity or harvest promptness where sowing was made after 25 January, because maturity occurred after the wet season was complete. In contrast, yield was optimised at early January sowing dates. Calculating gross margins by combining yield and weather damage simulations identified an optimum sowing date between the optimum for yield and seed quality. It was shown that later maturity combined with photoperiod sensitivity increased the sowing window from 10 to 29 days compared with a short duration variety that was insensitive to photoperiod. The relative merits of modelling and field experimentation in assessing the cropping potential for mungbean in a new region are discussed. The need to be able to simulate the yield of the second flush of flowers was acknowledged as a future research requirement.

Abstract The effect of irrigation and/or Ca (calcium) application on yield, grade and seed quality was studied using Florigiant peanuts planted on three dates. Calcium application resulted in a small, but consistent, yield increase at all planting dates. Irrigation resulted in a large yield response on early planted peanuts and no response on late planted ones. Grade, specifically sound mature kernel percentage, was improved by both Ca and irrigation treatments but the effects were only slightly additive. Similar interaction effects were noted as these treatments increased the germination percentage of the seed produced and decreased the percentage of kernels with the form of damage termed dark plumule. Both treatments also decreased the amount of watery hypocotyl damage and increased the Ca concentration in the seed. Germination was 89 to 94% when the seed Ca level was greater than 420 ppm, but fell linearly to 52% when the seed Ca decreased from 420 to 200 ppm.

       Cayenne pepper is a horticultural crop, which is attracted by consumers. In Kotawaringun Barat Regency in the last 3 (three) years of chilli, production continues to increase, but it is not yet known whether the cultivation is technical, price or economically.  The purpose of this research is to know the level of elasticity of production factors to the production of chilli pepper and know the level of technical efficiency, price, and economic farming chilli pepper in West Kotawarwant district.  The research was conducted in Kotawaringin Barat District in December 2019 to February 2020. The number of samples used is 100 farmers respondent, with simple random sampling method. Data used by primary data and secondary data.  Methods of data analysis using descriptive analysis, analysis of the Cobb-Douglass production function and analysis of technical efficiency, price/allocative, and economic. The results showed that the value of elasticity of the land area (0.501), seedlings (-0.201), fertilizer (0.112) and labour (0.386). The amount of elasticity 0.798 less than one indicates that chilli pepper farming is on a business scale (Decreasing return to scale), which contains the meaning of farming chilli pepper is not in the condition of a constant scale result.  The value of technical efficiency (0.199), the value of the efficiency of the price/Alokatif (0.0031), the value of economic efficiency (0.0022), the third value of efficiency less than 1, meaning farming chilli pepper inefficient so that the need to reduce the use of production factors.
