Abstract In a two year experiment carried out on the organic research plots of the Institute of Food Security, Environmental Resources and Agricultural Research, Nigeria. Two liquid organic fertilizers (ARATI NAWOZ {2.01% N} and ARATI BAJA {1.01% N}) and control were applied to four sunflower varieties (SAMSUN 1, SAMSUN 2, SAMSUN 3 and SAMSUN 4) during the late cropping season (July – Nov.) of 2016 and 2017 to evaluate their agronomic response. The experiment was laid out in a randomized complete block design using a 4 × 3 factorial arrangement in three replicates. Data were collected on plant height at maturity, head diameter and weight, weight and number of seeds per head, 100 seed weight and seed yield. The varietal effect was significant (P < 0.05) on head diameter and weight, and number and weight of seeds per head, and seed yield in 2016. However, during the markedly dry 2017, the varietal effect was not significant for any trait measured. Foliar application of ARATI NAWOZ significantly (P < 0.05) increased height at maturity, the weight of seeds and head per plant and seed yield relative to the control in both years. Significant Variety × Fertilizer interaction effect was also recorded on the height at maturity, head diameter and weight, and seed yield in 2016. SAMSUN 4 (975.6 kg/ha) produced significantly (P < 0.05) higher seed yield than SAMSUN 1 (789.82 kg/ha) and SAMSUN 2 (778.54 kg/ha) in 2016. The efficacy of the application of both fertilizers was on par for most traits in both years. On average, the application of organic fertilizers resulted in a 15.76 and 69.02% increase in seed yield relative to the control in 2016 and 2017, respectively. ARATI NAWOZ and ARATI BAJA appeared promising for sunflower production in the humid tropics.

This study evaluates the growth performance of lettuce (Lactuca sativa L.) utilizing various fermented products as organic fertilizers. Growth performance is determined through the plant’s weight and leaves and significant differences in growth among various treatments: (a) fish trash, (b) scrap seaweeds, (c) kangkong, and control groups urea (positive) and water (negative) was also determined. Kangkong leaves are fermented for 10 days, fish trash for 14 days and 1 month for seaweeds. Lettuce seeds are sown before transplanting (15 days after germination) into pots and placed in raised beds. Randomized complete block design is utilized in the experiment. Growth performance is measured through the number of leaves 10, 20, and 30 days after transplant and mass of plant upon harvest. After 30 days, the lettuce was harvested. Based on the findings, the soil and fermented products are acidic and the needed organic matter for optimum growth of lettuce are not sufficient as well as some nutrients of the fermented products. Among the organic fertilizers, kangkong at 30 ml performs best in terms of the growth performance of lettuce. Urea performs best in terms of the mass upon harvest. Significant differences exist in the mean number of leaves of lettuce treated with various amounts of organic fertilizers with the plants that receive urea. Lettuce produce more number of leaves and with the highest mass upon harvest when treated with urea compared with organic fertilizers applied after 30 days from transplant.

Low productivity characterizes the production of groundnut among smallholder farmers in Malawi. There is a need to explore options capable of increasing the productivity of the crop sustainably more especially under the changing climate. Against this background, experiments were conducted during the 2016/17 cropping season to investigate the potential to enhance the productivity of groundnut in Malawi through the combined use of inoculants (Graph-Ex and Histick-BASF) and foliar application of nutrients using Allwin fertilizer (legumes). The experiments were established at Bvumbwe and Chitala Agricultural research Stations and were laid in a randomized complete block design (RCBD) replicated four times. Data collected were analyzed in Genstat Discovery Edition 4 and were subjected to analysis of variance (ANOVA) at a 95% level of confidence. Means were separated by the least significant difference (LSD0.05). In general, foliar application of Allwin fertilizer alone particularly when conducted twice at two and four weeks after emergence produced a positive significant (p<0.05) groundnut grain yield response (97.8-170.8%) above the control. The yield increase is attributable to enhanced growth and development of the groundnut through the foliar supply of nutrients. In general, under the changing climate and amidst other constraints foliar feeding of nutrients using Allwin fertilizer alone particularly when conducted twice can increase significantly groundnut productivity in Malawi.

A field experiment was conducted to identify the best adapted and high yielding lentil variety at Shishinda sub-testing site of Bonga Agricultural Research Center during 2012 main cropping season. The experiment was carried out in randomized complete block design with three replications. Eleven improved lentil varieties were used for this study. The varieties included in the study were Teshale, Alemaya, Alemtena, Assano, Gudo, EL-142, R-186, Ada’a, Derso, Chalew and Chekol. The parameters studied in this experiment were days to flowering and maturity, plant height, number of pods plant-1, number of seeds pod-1, thousand seeds weight and grain yield. The analysis of the experiment showed significant (p<0.05) differences among varieties for all studied parameters. The varieties Assano, Alemtena, Derso, EL-142, and Gudo were found to be high yielder with the value of 1.71, 1.59, 1.39, 1.36 and 1.31 ton ha-1, respectively. In addition, farmers were invited to evaluate the performance of the tested varieties under field condition. Eventually, the farmers selected Assano and Alemtena as the most preferred varieties. Therefore, these varieties can be suggested to use for wider production in the study area. The involvement of farmers in variety selection processes may increases the adoption of new variety in the area. Int. J. Agril. Res. Innov. Tech. 9(2): 9-14, December 2019

This study was performed to evaluation of interaction of silicon application and irrigation on agronomic and physiologic traits of safflower at 2018 and 2019. The experiment was conducted as a split plot factorial based on randomized complete block design with 3 replications. The irrigation was main factor (0, 2 and 4 times during growth) and the sub-factor were silicon foliar application (at three levels: 0, 1 and 2 mM) and three safflower cultivars (Goldasht, Padideh and Golmehr). The studied traits were: number of seeds per boll and 1000-grain weight, number and weight of boll, number of lateral branches and branch diameter, plant weight and total plant weight, floret yield, grain yield, chlorophyll a and b, proline and antioxidant enzymes. According to results, treatments had significant effects on studied traits at 5 or 1% statistically level. 2 and 3 times irrigation led to 7 and 24% the increasing of seed yield in compare to control, respectively. It was obtained that 1 and 2mM silicon led to 25 and 15% the increase of seed yield in compare to control. Interaction between treatments showed that the highest seed yield (500g per m2) was observed by Goldasht cultivar under 4-time irrigation and 2mM silicon. Therefore, it can be suggested that Goldasht with 2 mM silicon be used to reduce the effects of dehydration.

Abstract The effects of sowing seasons and chemical, organic and biological fertilizer sources were explored on morphological traits of dragon’s head (Lallemantia iberica Fish.) in a field experiment based on a randomized complete block design in three replications and six treatments. The fertilization treatments included organic fertilizers (vermicompost, manure, and humic acid), biological fertilizer (Thiobacillus mixed with sulfur), chemical fertilizer (macro NPK), and control (no-fertilization). The recorded traits included leaf area index, plant height, number of flower cycles per plant, number of achenes per plant, number of seeds per plant, 1000-seed weight, number of auxiliary branches, plant diameter, and the uptake of nitrogen, potassium, phosphorus, calcium, and sodium. The results showed that the winter sowing outperformed the spring sowing by a wide margin and results obtained for morphological traits were significantly higher than those of the spring sowing. The fertilization of the plants in both sowing seasons, especially in the winter sowing, improved yield and yield components. The uptake of N and K was not influenced by the sowing season and fertilizer type, whereas the uptake of P, Ca, and Na was influenced by these factors but with a slight difference. It can, so, be inferred that the uptake of nutrients in dragon’s heads is less influenced by the environment. Overall results indicated that the improvement of morphological traits in the ecological conditions of Azerbaijan region (Iran) was most notable for winter sowing of dragon’s heads with the use of Thiobacillus and vermicompost fertilizers.

Improved soil fertility is a requirement for enhanced crop production. Combination of inorganic and organic fertilizers improve crop productivity while reduce environmental degradation. An experiment was carried out at Eastern University, Sri Lanka to study the effect of Foliar Application of Banana Pseudostem Sap on Yield of Cowpea (Vigna unguiculata L. Walp.) in sandy regosol. The experiment was laid out in Randomized Complete Block Design having five treatments viz; recommended inorganic fertilizer N, P, K as basal and N as topdressing (T1), N, P, 1⁄2 K as basal with recommended N as topdressing and foliar spray of 1% , 3%, 5% and 7% banana pseudostem sap solution (T2-T5) at 3rd, 5th, 7th and 9th week after planting. The results revealed that significant difference (P<0.05) were noted on number of pods per plant at 1st and 2nd picking. Higher number of pods per plant, maximum pod length and girth were in T2 while low in T1. Sun dried weights of pods and number of seeds per pod were significantly (P<0.05) varied at each picking. Further, cowpea yield at each picking were higher in T2 compared to tested treatments. The present study suggested that, among the tested treatments N, P, 1⁄2 K as basal with recommended N as topdressing and foliar spray of 1% Pseudostem sap solution at 3rd, 5th, 7th and 9th WAP would be the most suitable for cowpea production in sandy regosol.

Lentil crop has largely been affected by global climate changing, particularly, due to rainfall and temperature changing and variability. Hence, the experiment was conducted in Central Highlands of Ethiopia, namely Akaki, Chefe Donsa and Bishoftu Agricultural Research Centre, in the 2009 and 2010 cropping seasons to assess the genotypic variation of lentil for growth and yield performances. Five lentil genotypes viz. 87S-93549 X EL-103-16, 87S-93549 X EL-103-9-1, Alemaya X FLIP 88-41L-02-AK-14, Alemaya X FLIP 88-41L-02-AK-6 were arranged in randomized complete block design with four replications at all locations. The result of study revealed that the genotype 87S-93549 X EL-103-9-1 produced the highest seed yield of 1985.90 and 2500.00 kg ha-1 during 2009 and 2010 cropping seasons, respectively, at Akaki. On the other hand, the genotype Alemaya X FLIP 88-41L-02-AK-14 gave the highest seed yield (4189.1 kg ha-1) at Chefe Donsa in 2009 cropping season. The genotype X FLIP 88-41L-02-AK-14 was found to be the earliest in physiological maturity, accounting 128.75 days, and the genotype 87S-93549 X EL-103-9-1 had yield advantage of 27.6% over the local check at Chefe Donsa in the 2010 cropping season. Generally, all lentil genotypes were performed better at Chefe Donsa, followed by at Akaki and Bishoftu locations during both cropping seasons. Rainfall and temperature conditions have enormous influences on the growth and yields performances of lentil genotypes at all research locations. The study inspires other studies to be conducted on other factors than climate events thwarting the production of lentil crops in the study areas.

Essential Oil Yield

The quantitative yield and essential oil percentage and composition of two important savory species in response to various fertilizers were explored in a field experiment as a factorial study based on a randomized complete block design with three replications in north Lorestan, Iran, in 2017–2019. The first factor was assigned to three mycorrhizal fungi (Funneliformis mosseae, Rhizophagus irregularis, and Glomus fasciculatum), phosphate biofertilizer (Baravar-2), fish manure (800 kg/ha), cattle manure (20 t/ha), vermicompost (5 t/ha), and a control (no fertilization); the second factor was assigned to two savory species, including Satureja khuzestanica and S. rechingeri. The results of the combined analysis of variance for the second and third years showed that the simple effects of fertilizers and species were significant on all recorded traits, except for some constituents of the essential oil. Among the mycorrhizal fungi, R. irregularis and S. khuzestanica outperformed S. rechingeri in all traits, except for essential oil content and yield. The interaction between year and species was significant for all traits. The essential oil content of S. rechingeri in the third year (5.1%) was 18% higher than that of S. rechingeri in the second year (4.3%) and 41% higher than that of S. khuzestanica in the third year (3.6%). According to the results, the foliar application of vermin compost at a rate of 5 t/ha can contribute to the sustainable production of both savory species, improving their growth and essential oil yield.
