Due to increasing popularity and use of agro-chemicals to control pests and diseases on fields, applicators of these pesticides, consumers of agricultural products and other living organisms are exposed to the dangers of these chemicals if not used properly. To mitigate these dangers and general environmental pollutions, farmers need to be trained on the dos and don’ts that ensure safer usage and increased efficacy. Key protection measures like use of right spraying equipment and wearing personal protective equipment such as waterproof apron, rubber gloves, gumboots, and breathing masks should be adhered to. Farmers should be reminded to read and follow properly the product labels provided before handling any chemical. In the case of using pesticide tank mixes, care must be taken to ensure that individual chemicals are miscible and never react to each other. The information on using tank mixes could be found from the product labels, approved and certified agro-dealers or agricultural extension officers. Remaining and or unused pesticide products must be stored safely under cool temperature and locked out of reach of children. Proper disposal of expired chemicals and their containers must be guaranteed.

To determine the effect of Organic-based Fortified Foliar Fertilizer (OFF) on the growth and yield of ‘Lakatan’ banana, this study was conducted at the University of Southeastern Philippines, Tagum – Mabini Campus, Mabini Unit, Mampising, Mabini, Compostela Valley Province, from December 2015 to March 2016.         

The experiment was laid out in Completely Randomized Design (CRD) with six treatments replicated three times. The treatments were: T1- control; T2- Recommended Rate of NPK fertilizer/ha; T3 - ½ RR of NPK/ha; T4 –Organic-based Fortified Foliar fertilizer (OFF) at 100 ml/16 liters of water; T5 - ½ RR of NPK + OFF; and T6 - RR of NPK + OFF.

Results showed that no significant effects were observed in terms of the plant height at 15, 30, 45 days after application (DAA), pseudostem girth at 15, 30, 45 DAA, and number of hands per bunch. However, significant differences were obtained in the number of leaves, number of fingers per bunch, fruit weight (kg) and yield (tons/ha) of ‘Lakatan’ banana.

The highest number of leaves were obtained in T6 – RR of NPK fertilizer/ha + OFF which is comparable to T5 – ½ RR of NPK fertilizer/ha + OFF. T6 – RR of NPK+ OFF also had the highest number of fingers per hand than the rest of the treatments as much as 21% higher than the control. The fruit weight of T6 – RR of NPK+ OFF has 61% higher than untreated and the yield of 37 tons/ha is higher than the national average yield of 9.4 tons/ha in ‘Lakatan’ banana.

Soybean is one of the main food crops in Democratic Republic of Congo (DRC). Its production is ensured mainly by farmers who use seeds of various origins. However, yields obtained with this crop remain low because of seed-borne diseases that also affect the quality of the seeds.

Twenty – two batches of seeds collected in the Democratic Republic of Congo were analyzed. The average values ​​of weight purity recorded ranged from 79 to 100 %, germination rates from 0 % to 86.6 % and seed weight from 71.1 to 152 g. Several phytopathogenic agents have been identified on both certified variety and landraces. The fungus Fusarium solani F.sp Glycine, Aspergillus sp, Rhizoctonia solani, Phomopsis longicola, Xanthomonas axonopodis pv. Glycine and Pseudomonas syringae pv Glycine have been identified.

This work aimed mainly at comparison among non-segregating (P1, P2 and F1) and segregating (F2, BC1 and BC2) generations using genetic parameters for four traits in the cross Eg27 x Fc723 cmsduring 2015 to 2018 in Ras-Sudr station, Desert Research Center (DRC), South Sinai and Private Farm in Kafr El Sheikh Governorate. According to combined analysis of variance, highly significant environments (E) for all studied traits and significant or highly significant genotype (G) and GxE interactions for most traits were observed during six generations. In respect to mean performances, Kafr El-Shiekh location was higher than Ras-Sudr location for most studied traits at six generations. Significant differences among six generation means were found for all studied traits in the two locations. The F2 generation was lower than the P1, P2, F1, BC1 and BC2 generations for most studied traits at the two locations. The cross (Eg27 x Fc723 cms) recorded positive and highly significant heterosis, heterobeltiosis and inbreeding depression for most studied traits under two locations. A high broad sense heritability and genetic advance as percent of mean (GAM%) estimates were observed for root diameter/plant at BC1, root weight/plant at BC2 and T.S.S.% at BC1 and BC2. Generally, the values of the all studied genetic parameters for all studied traits during segregating generations were higher than non-segregating generations. The principal component analysis of the relationship between the six generations revealed that the most appropriate generations for selecting these traits were BC1 and BC2 under the two locations. Backcrossing may be done for 2–5 cycles (BC2 – BC5) at Eg27 parent for improving sugar beet yield in Egypt.

Seed dormancy in wheat (Triticum aestivum L.) is a major problem attributing to yield loss. It is a complex evolutionary trait that temporarily prevents seed germination, thus allowing seedling growth at a favorable season. This experiment was conducted to determine the effect of different pre-treatments on germination. The pre-germination treatments included mechanical scarification, soaking seeds in hot water at 100°C for 5 minutes, cold water for 24 hours and untreated (control). Two hundred seeds were used for each treatment. Seeds treated with cold and hot water commenced germination after 4 days and achieved 84%, 78.5% respectively germination within 10 days which was significantly different (P < 0.05) from other treatments, especially the untreated seeds which had the lowest germination of 30%, and commenced first germination after 10 days. The results showed significant differences (P < 0.05) in germination percentage and germination time. Results obtained in this experiment indicate that the pre-germination treatment of Farasi wheat seeds by using cold and hot water treatments can enhance germination of the seeds by breaking dormancy.
