Introduction
 Asiatic Garden Beetles (Maladera castanea, AGB)
are a common turf and ornamental pest, are
now causing economic damage on field corn
 The larva feed on roots, declining stand height,
and plant population
 Control with seed treatments have been mixed,
and data are lacking on efficacy of other control
mechanisms
 On-farm research trials were established during
the 2014 production season to evaluate three
soil applied insecticides on grain yield.
Objective
 To evaluate soil insecticide efficacy on AGB
larvae and ability to protect against yield loss
 Field length, on farm research plots were
established in 2014 in Fulton County on three
separate farms affected by AGB in the past.
 Trials were a randomized complete block design
with three treatments, replicated four times.
 Treatments were 1) untreated, 2) Lorsban or
Empower and 3) Capture LFR at planting.
 All plots were planted with the same planter
using Pioneer 0636AMX seed at a rate of 33,000-
34,000 seeds per acre.
 AGB larva pressure, harvest moisture, and dry
yield were recorded.
 Data were analyzed using a simple ANOVA
procedure. Factors were considered statistically
significant at α = 0.05

Conclusions
 AGB larvae were easily found in all farms, and could be found
between and within rows
 Yields among farms differed substantially, yet there were no
significant differences in yield
 Despite the AGB pressure and its visible impacts on corn plants,
damage in these trials appeared minimal, perhaps due to
compensation from other, undamaged plants
 Future work will repeat these trials to obtain multiple years of data

The comparative efficiency of organic and synthetic fertilizers were studied on maize and cowpea, two staple Nigerian crops. Chemical fertilizer did not support yield as much as poultry manure (PM) or arbuscular mycorrhizal fungi(AMF), individual or in a combined state. The combination of PM and AMF was the best application expressing yield in form of shoot productivity. Glomus clarum was a good fertilizing candidate in this study

Glyphosate-resistant (GR) soybean was one of the first major applications of genetic engineering in field crops and offered farmers a vital tool in fighting weeds. Weeds are a problem for soybean production in Cuba, so our work aim was the GTS 40-3-2 event introgression into Cuban varieties. Two local cultivars were crossed with transgenic genotypes that carry the event. From F1 to F3 generations, individual plants that produced more than 60 g of seeds per plant were chosen to obtain next generation. Individual lines were selected from F4 generation. F5 and F6 generations of five selected transgenic lines and their relatives were chosen to evaluate seven agronomic traits throughout the summers of 2012 and 2013. A Random Block experimental design was done. First flowering (R1) and maturity (R8) stages of all genotypes were affected by planting date. Plant height of I1B2- 3, I1B4, I36B4 and RP5 lines ranged from 80 to 111 cm. I1B2-2 and I1B2-3 lines would be suitable for mechanized harvesting because they had the insertion of the first pod at 14.63 cm and 13.93 cm respectively. I36B4 line produced the greatest number of pods per plant (127). Transgenic lines produced more than 180 seeds per plant and 100-seed weight ranged from 13.75 g to 17.46 g. Seed yield per plant of transgenic lines and their parents IncaSoy36, CEB2 and CEB4 weren’t statistically different. These results could be a start point for other studies involving larger areas, different planting dates and localities.

Genetic control and heterosis depend directly on genetic divergence among the parents in generating promising hybrids required by plant breeders. The purpose of this study was to determine the relative importance of heterosis, combining abilities, regression and correlation estimates in order to develop hybrid cultivars in maize. The 28 F1 hybrids obtained by partial diallel cross of 8 inbreds in a randomized complete block design were evaluated at the Lower Niger River Basin Authority, Oke-Oyi, Nigeria in three years. General (GCA) and specific combining abilities (SCA) produced significant (P < 0.01) effects for all the characters, while non-additive genetic effects were predominant. The levels of heterosis for grain yield varied widely among crosses, ranging from -16.83 to 9.76%. Positive and significant genotypic and phenotypic correlations among grain yield and some related characters (days to anthesis and silking; plant and ear heights; number of ears plant-1 and 1000 seed weight) showed that each character could be used indirectly to selection of grain yield. These results also indicated that SCA was more effective than heterosis for describing hybrid performance. The regression of actual hybrid characters on the expected hybrid characters, based on parental GCA values, was highly significant. Regression analysis also showed that all the agronomic characters jointly contributed 19.4% to grain yield of maize. The inbreds (Pop 66 SR and 2000 EV DT-Y STRC4) and crosses (Pop 66 SR x, 2000 EV DT-Y STRC4, Pop 66 SR x KU1409 and 9006 x KU1409) featured prominently with respect to better GCA × Year and SCA × Year effects with high heterotic values for maize grain yield and associated characters. These inbreds could serve as donors to obtain early and short statured hybrids with higher yield, while the crosses may be exploited and adapted to the Nigerian Savannas. This study also affirmed that genotypic and phenotypic correlation coefficients as well as combining abilities, heterosis and regression analyses were found to be suitable models for yield improvement in maize breeding.

A study of sorghum tolerance to low P condition was conducted in two experiments : (1) in nutrient solution and (2) in acid soil. The aim of this study was to obtain information on the genetic variability and heritability of agronomic characters that could be used as selection criteria in low P condition and to obtain information on gene action that controlled agronomic characters of sorghum.The plant materials used in this experiment were F2 segregating population derived from the cross between B69 and Numbu. The first experiment was conducted in the green house of Bogor Agricultural University. B69, Numbu and F2 population were grown hidroponically for 14 days. Composition of the nutrient solution used in the experiment followed the method suggested by Ohki with modification of P concentration. P is given in the form of KH2PO4: 0.001 mM. The results showed that shoot dry weight (SDW) and total dry weight (TDW) had high estimate of heritability and moderate genotypic coefficient of variance (GCV), thus these characters can be used for criteria selection for low P tolerance at seedling stage. The significant value of skweness from the distribution shoot dry weight in F2 segregants, indicate the presence of complementary epistasis gene action, whereas normal distribution of total dry weight showed additive gene action. The second experiment was conducted in acid soils of Bogor District Experimental Field Tenjo, Bogor. The results showed that stem diameter, panicle weight and grain yield per plant had high heritability and wide GCV value, indicating these characters can be used as the selection criteria in selecting sorghum genotypes for low P tolerance in acid soil. Based on the skewness values, all of the agronomy characters observed in this study were influenced by additive gene action.

Faba bean (Vicia faba L.) is one of the most important legumes used for food, feed and maintaining ecological balance. However, its productivity has been declining due to various biotic and abiotic factors. Arbuscular Mycorrhizal symbioses have been proved to enhance growth and yield responses of faba bean and other agricultural crops by counteracting these extreme factors. The study was conducted at field and greenhouse to evaluate the performance of faba bean genotypes for mycorrhizal colonization on two Phosphorus fertilizer levels. Randomized Complete Block Design with three replications was used. Analysis of variance indicated that all parameters, except number of mycorrhizal spores and relative mycorrhizal dependency, were highly significantly (p<0.01) varied for genotypes. Genotypes Wayu, Dosha, Didea, Moti and Tumsa for phosphorus fertilized; and Dagim, Gebelcho, Dosha, Tumsa and Wayu for unfertilized trial had performed better. Mycorrhizal colonization performance was higher on unfertilized than on P fertilized trial, at both field and greenhouse. Furthermore, for the genotypes tested at both conditions, the performance of the genotypes was higher at field than at greenhouse. The study also revealed that most of the mycorrhizal association parameters were highly correlated with biomass phosphorus uptake and grain yield of the faba bean genotypes.

Field trial was conducted in 1999 and 2000 at Samaru in the northern Guinea Savanna ecology of Nigeria to assess the reaction of 36 groundnut genotypes to Alectra vogelii (Benth). The research field was naturally infested with Alectra. The trial was laid out in randomized complete block design (RCBD) with three replications. The path coefficient analysis of the yield attributes showed that number of pods plant-1 exhibited the highest percentage yield contribution of 41.46% to kernel yield. This was followed by 100 kernel weight which contributed 13.80%. The highest combined contribution of 6.23% came from 100 kernel weight and haulm yield. The residual contribution was 23, 24%.

Field experiments were conducted to investigate the variations in sixteen maize genotypes in relation to drought tolerance. The experimental set up was subjected to drought stress after five weeks of planting for three weeks before data on morphological and yield characters of maize genotypes were obtained for three cropping years. Plant height and grain yield of Bodija yellow maize were the highest overall. There was a significant difference among genotypes for drought stress resistance and Bodija yellow maize showed the most tolerance, while TZBR Comp 1 – C1 S2 510 genotype was the least. First principal component axis (Prin 1) had the highest contribution to the variation of the morphological, yield and drought tolerance traits. Prin 1 was highly related to the morphological and yield characters more than to the drought resistance. Plant height was negatively and strongly correlated (p<0.01) with stem height, number of leaves, stem girth, leaf length, leaf width and week after planting, but negatively correlated with the drought resistance. Therefore, Bodija yellow maize should be considered as parent material in breeding for the development of drought tolerant traits in maize.

In the substitution of chemical insecticides with potential biopesticides, the efficiency of Lippia multiflora, Plectranthus glandulosus and Callistemon rigidus were evaluated on the improvement of cowpea (Vinia unguiculata) in Dang (Ngaoundere, Cameroon). The experiment was conducted in a completely randomized block design with 5 treatments repeated 4 times each: the negative control, the positive control (Decis), L. multiflora, P. glandulosus and C. rigidus. These different insecticides were sprayed on cowpea plants with 14 days interval starting from the 14th day after sowing. The parameters collected were the diversity of insect pests, the number of pods, and the dry weight of the grains. All of the insecticides used improved cowpea yields. Although less efficient than Decis, most biopesticides significantly (p < 0.001) improved the yield of cowpeas compared to the negative control. This improvement was 260% for C. rigidus, and 120% for P. glandulosus. These results suggest that C. rigidus, P. glandulosus and L. multiflora could be considered as potential substitutes for chemical insecticides in improving cowpea yields.

Hassan Abdi1*, M. Taheri Mazandarani2 1, 2Research Instructor, Department of Seed and Plant Improvement, Agricultural and Natural Resources Research Center, Tehran, Iran ABSTRACT- In order to study drought tolerance indices and identify drought tolerant genotypes in wheat, 40 improved wheat varieties (three digits and thirty-seven new lines) in a randomized complete block design with three replications under normal conditions and drought stress (50% flowering) in 2011-2012 on Agriculture and Natural Resources Research Center of Tehran province were studied. Under normal grain yield and drought tolerance quantitative indicators such as the average productivity, geometric mean productivity, stress tolerance, harmonic mean, sensitivity to stress, stress tolerance index were calculated. 6, 37, 38 and 39 genotype with the highest values of mean productivity, geometric mean, harmonic and stress tolerance index were average. 5, 19 and 40 genotypes maximum of sensitivity to stress and drought tolerance and sensitivity respectively. Biplot analysis showed that genotype vectors in the vicinity of 37.38 and 39 indicators mean productivity, geometric mean productivity, stress tolerance index and harmonic mean as drought tolerant genotypes. Evaluation shows that the studied genotypes 37.38, 39 and 27 were tolerant. Key-words- Bread wheat, Stress tolerance indices

Development of drought tolerant maize cultivars is prerequisite to achieving stable grain yield in drought–prone ecologies of Nigeria’s Guinea savanna. However, success has been limited mainly due to lack of maize genotypes that show clear differences in response to well defined moisture deficit condition. Two sets of drought tolerant (DT) maize germplasm were evaluated under screenhouse and field conditions between 1999 and 2002. In the screenhouse study, performances of the genotypes were compared under well-watered condition and moisture deficit imposed at different growth stages. Under field conditions, the first set comprising 11 accessions along with a check were evaluated for 4 growing seasons while the second set which comprised 3 DT varieties were evaluated along with 2 check varieties using monthly plantings between April and August of 2001 and 2002, respectively. In the first set, post anthesis moisture deficit significantly reduced grain yield by 25 to 73.5% in the open pollinated varieties (OPVs) and by 20 to 64% in the hybrids. Grain yield under field conditions ranged from 2.48 to 3.49, 2.82 to 3.73 and 3.58 to 4.76 tons/ha-1 for 1999, 2000 and 2001 full growing seasons, respectively, and 2.03 to 2.50 tons/ha-1 for 2000 late growing season. In the second set, pre and post anthesis moisture deficits reduced grain yield by 77.6 and 95.8%, respectively, of well watered condition while in the field, grain yields in the genotypes were highest for plantings made in April and July (1.90 - 2.5 t/ha), lowest for August (0.7 -1.8 t/ha) when moisture deficit coincided with reproductive phase. Yield stability exhibited under moisture deficit and on the field by 8522-2, Oba super 2 and AK9943-DMRSR in the first set as well as DT-SR-Y C0 and DT-SR-W C0 in the second set, indicates their suitability either as cultivars per se or as potential source of DT alleles for development of DT maize varieties for Nigeria’s savanna ecologies.
