Agronomic Performance of Soybean Genotypes in Lowland Paddy Fields under Zero-tillage Condition

In Indonesia, soybean is mostly cultivated in lowland following the yearly planting pattern of paddy – paddy – soybean under zero-tillage condition. The research aim was to evaluate the agronomic performance of several soybean genotypes in lowland paddy fields under zero-tillage condition. A total of 12 soybean genotypes, including the check varieties of Wilis and Anjasmoro, were evaluated in lowland after rice planting in three locations (Klaten, Pasuruan, and Tabanan). A randomized block design with four replications was used in each location. The soybean yield is a complex character which determined by interrelated agronomic characters. The averages seed yield in Klaten, Pasuruan, and Tabanan were 2.97 t/ha, 3.02 t/ha, and 2.68 t/ha, respectively. Two genotypes produced equal yield with Anjasmoro, i.e. AT12-1062 (3.01 t/ha) and AT12-1037 (3.0 t/ha). Anjasmoro variety had the highest 100 seed weight (15.40 g), and only AT12-1035 showed the equal seed weight. The average days to maturity of 12 genotypes was 83 days. In addition to Anjasmoro variety, soybean genotypes AT12-1062 and AT12-1037 (medium maturity and medium seed size) as the new findings form this study were potential to be developed at lowland paddy fields under zero-tillage condition. The availability of the soybean genotypes adaptive to lowland paddy field under zero tillage condition is important to optimize the soybean productivity as well as the income of farmers in Indonesia.

Abstract. Krisnawati A, Adie MM. 2021. Agronomic performance and pod shattering resistance of soybean genotypes with various pod and seed colors. Biodiversitas 22: 474-481. Climate change impacts agricultural production, including the increase of the yield loss in soybean due to pod shattering. This research aimed to identify the pod shattering resistance and agronomic performance of several soybean genotypes with various pod and seed colors. A total of 100 soybean genotypes were planted in Malang (East Java, Indonesia) during the dry season 2019. The field experiment was laid out in a randomized block design with three replications. The pod shattering resistance was assessed using the oven-dry method. The pod shattering resistance of 97 genotypes were classified into 20 very resistant genotypes, 17 resistant genotypes, 15 moderate genotypes, nine susceptible, and 36 very susceptible genotypes. The pod colors did not affect the pod shattering resistance in soybean. The new findings from this study, i.e., two very resistant genotypes (G42 and G15) which produce high yield and have medium maturity, were suggested to be developed as new cultivars, meanwhile, the other very resistant genotypes can be used in the soybean breeding program to develop shattering resistant cultivar with desirable traits.

ABSTRACT: The Roundup Ready (RR) soybean was developed for weed control with the use of glyphosate. Some herbicide combinations with glyphosate has been used in weed control and some effects of this practice may be undesirable in the agronomic performance of RR soybean. The present study evaluated the agronomic performance of RR2 intact soybean applied with associations between herbicides and glyphosate at post-emergence, in two experiments conducted in two municipalities in the state of Paraná, Palotina and Marechal Cândido Rondon. This experiment consisted of seven treatments in a randomized block design with four replications, totaling 28 plots for each municipality. The cultivar used in both experiments was Monsoy 6210 Intact RR2 IPROTM. The variables analyzed were: phytotoxicity at 3, 7, 14, 21 and 28 days after application, chlorophyll A, B and total chlorophyll, final height, number of pods, 100 seed weight and yield. Data were analyzed by analysis of variance and Tukey’s test at 5%. There were differences between treatments for phytotoxicity in both locations and differences in yield (Palotina) and final height (Marechal Cândido Rondon). From the data it is understood that some associations of certain herbicides such as lactofen, chlorimuron-ethyl in the glyphosate can potentiating effect cause phytotoxicity and even reduction in productivity.

Background: Pod shattering has become the major problem in soybean production. The research aims to identify the pod shattering resistance and to assess the agronomic performances of 50 soybean genotypes and the association among agronomic characters. Methods: The research materials were 50 soybean genotypes which consisted of 47 lines derived from routine crossing programs and three check cultivars. The field experiment was arranged in a randomized block design with two replications. The data were observed for yield and its component traits. The oven-dry method was performed in the laboratory to assess the pod shattering resistance. Result: Variation among genotypes was found in the pod shattering resistance and agronomic characters. The genotype by trait biplot graph showed that pod shattering was negatively correlated with the days to maturity and plant height, but positively correlated with the seed size. Soybean genotypes of Grob/G100H-1-588 and G100H/Mhmr-4-993 were resistant to pod shattering and have a high seed weight per plant. These genotypes were potential for further varietal development or could be used as gene sources in the soybean improvement program for pod shattering resistance.

The research was conducted at three locations of rubber tree plantation in Central and East Lampung where the rubber tree were at age of 3 to 4 years, during dry season of 2011. The materials consisted of 30 soybean genotypes, where 23 lines were shadetolerant, and seven were as check varieties (Pangrango, Burangrang, Malabar, Argomulyo, Grobogan, Ijen, and Tanggamus). Each genotype was planted in plot of 4 m x 2.2 m, plant spacing was 40 cm x 15 cm, two plants /hill. The experiment used a randomized block design, repeated four times. Before planting, dolomite of 1.5 t/ha was applied, and 75 kg Urea / ha + 100 SP36 kg/ha + 100 kg KCl /ha was applied at planting time. Observations were done on flowering date, harvesting date, plant height, number of branches, number of reproductive nodes, number of pods, seed weight per plant and grain yield. The light intensity under the rubber tree canopy was observed every week after the soybean age was 30 days (DAP), at 11:00 to 12:00 pm. The levels of shade made by the rubber tree canopy at three locations were different; at Tulangbalak (East Lampung) and Gunungsari (Central Lampung) ranged between 20% to 40%, at Gunungadi (Central Lampung) between 40% to 60%. Genotypes IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 yielded consistently well in two locations, in East Lampung (1.40 t/ha and 1.43 t/ha), in Central Lampung (1.19 t/ha and 1.18 t/ha). Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 produced the highest average yield out of the three locations, i.e 1.13 t/ha. Genotype IBM22-861-2-22-3-1 and AI26-1114-8-28-1-2 were considered as suitable genotypes for planting under the rubber tree of 3 to 4 years of age.</p>

ABSTRACT The objective of this study was to investigate the effect of interaction between nitrogen topdressing and different application ways (active ingredients) a.i. fluazifop-p-butyl + fomesafen in weed control and agronomic performance of common bean. The experiment was conducted during winter 2003 in Selvíria/MS. The experimental design used was a randomized block design with four replications in a factorial scheme 2x7. The first factor was composed by the absence or presence of nitrogen topdressing, while the second factor consisted of different application ways of fluazifop-p-butyl + fomesafen. The following variables were measured: leaf N content, dry matter of plants, yield components (number of pods plant-1, number of grains plant-1, the average number of grains pod-1 and mass of 100 grains), grain yield, phytotoxicity and weed control percentage. The nitrogen topdressing with 75 kg ha-1provided higher dry matter of plants, higher weed control and higher common bean yield of irrigated winter. In the absence of nitrogen topdressing in the application of urea before or together to fluazifop-p-butyl + fomesafen increased their effectiveness in controlling weeds without interference in the agronomic performance of common bean.

The current investigation was carried out to examine the selection criteria for yield improvement in selected genotypes of Indian mustard. Twenty-four genotypes of Indian mustard were evaluated for seed yield and yield attributing characters with randomized block design with three replications. The analysis of variance showed significant differences among all the 24 genotypes against all the characters. The phenotypic and genotypic coefficient of variation were higher for most of the traits like seed yield per plant, number of secondary branches per plant and number of siliquae per plant. High heritability coupled with high genetic advance in percent of mean was registered for number of siliquae per plant, number of primary and secondary branches per plant, plant height, 1000 seed weight, siliqua length per plant and seed yield per plant suggesting predominant role of additive gene action for expression of these traits. The correlation study revealed that seed yield per plant was positively and significantly correlated with number of primary and secondary branches per plant, number of siliquae per plant, siliqua length per plant and 1000 seed weight at both phenotypic and genotypic level. The traits namely, number of secondary branches per plant recorded as highest positive direct effect followed by number of seeds per siliqua, number of siliquae per plant and plant height. Therefore, they may be carried out further evaluation in multilocational trials, biotic and abiotic stress like environmental conditions to check their stability and adaptability.

ABSTRACT: Conyza spp. is among the main weeds reported worldwide. Due to its aggressiveness, such as high seed production and dispersion, and the growing reports of biotypes resistant to glyphosate, paraquat, and other herbicides, different control practices are required. Thus, this study aimed to evaluate the efficacy of herbicides with sequential application of glufosinate in soybean pre-sowing for control of Conyza spp. with indicative of resistant to paraquat. The study was carried out in the field, at Assis Chateaubriand and Palotina, state of Paraná, Brazil, in the 2018/19 season. The experiments were conducted in a randomized block design with four replications. The treatments consisted in application of glyphosate, 2,4-D, saflufenacil, glufosinate, saflufenacil/imazethapyr, diclosulam, paraquat/diuron, paraquat and imazethapyr/flumioxazin, at different combinations, in soybean pre-sowing. Control of Conyza spp., crop injury to soybean plants and variables related to agronomic performance (plant height and yield) were evaluated. All treatments were selective for soybean, which showed stronger crop injury in the presence of diclosulam herbicide, but this did not compromise soybean agronomic performance. In general, control levels were high for the treatments used. Except for paraquat treatments, in the area with the highest frequency of Conyza spp. with indicative of resistant to paraquat, and imazethapyr/flumioxazin treatment in both areas. These control results emphasized the importance of glufosinate in this management system and showed promising results for saflufenacil/imazethapyr.

Long bean production in Indonesia continues to decline every year, this is due to land conversion and the lack of application of agricultural technology. One of the efforts to increase long bean production is by multiplying quality seeds using organic materials as nutrients needed by plants. This study aims to determine the response of the growth and production of long bean seeds to the interaction of strains, varieties with a concentration of liquid organic fertilizer. The research was conducted at the Vegetable Crops Research Institute, Lembang, West Bandung Regency from July 2020 to January 2021. The research method used was an experimental method with a Randomized Block Design (RBD) with a split-plot design consisting of 2 factors: the first factor (main plot) (A) was the variety and strain with 2 levels, a1 (Tavi canton variety) and a2 (pras-1 strain).The second factor (subplot) (B) is concentration of biopras-1 with 5 levels, b1 (0 cc/l-1 water), b2 (1 cc/l-1 water), b3 (2 cc/l-1 water), b4 (3 cc/l-1 water) and b5 (4 cc/l-1 water). The effect of the treatment was analyzed by means of variance and if the f test at 5% level was significantly different, then to find out the best treatment was continued with the DMRT (Duncan Multiple Range Test) at the 5% level. The results showed that there was an interaction between varieties, lines with various concentrations of biopras-1 liquid organic fertilizer on dry seed weight per plant, dry seed weight per plot, and 1000 seeds weight. Treatment of pras-1 lines with the concentration of liquid organic fertilizer biopras-1 4 cc / l of water was able to give the best results on dry seed weight per plant (35.31 gr), dry seed weight per plot (1.298.20 gr or 2.16 Ton/ha-1) and the weight of 1000 seeds (153.10 gr).
