Waterlogging stress adversely affects crop growth and yield worldwide. Effect of sodium azide priming on waterlogging stress tolerance of okra plants was investigated. The study was conducted as a field experiment using two weeks old plants grown from 0%, 0.02%, and 0.05% sodium azide (NaN3)-treated seeds. The waterlogging conditions applied were categorized into control, one week, and two weeks. Different growth and reproductive parameters were investigated. Activity and expression of antioxidant enzymes, root anatomy, and soil chemical analysis were also studied. Results showed that sodium azide priming inhibited germination. The germination percentages recorded were 92.50, 85.00, and 65.00 for 0%, 0.02%, and 0.05% NaN3-treated seeds, respectively, nine days after planting. Waterlogging conditions depressed plant height ten weeks after planting. Under waterlogging conditions, NaN3 promoted plant height and number of leaves formed. NaN3 also supported the survival of plants and formation of adventitious roots under waterlogging conditions. Waterlogging conditions negatively affected the redox potential, organic C, N, and P concentrations in the soil but enhanced Soil pH, Fe, Mn, Zn, and SO4. Under waterlogging conditions, NaN3 increased the average number of flower buds, flowers, and fruits produced in comparison to control. Moreover, NaN3 highly stimulated the development of aerenchyma which in turn enhanced the survival of okra plants under waterlogging conditions. NaN3 priming also enhanced the activities and gene expression level of antioxidant enzymes (ascorbate peroxidase, APX; catalase, CAT) under waterlogging conditions. In conclusion, this study demonstrated that NaN3 priming could improve waterlogging stress tolerance in okra.

An experiment was conducted with a local cultivar of garlic to study the effects of planting date and gibberellic acid on the growth and yield of garlic at the field laboratory of the Department of Crop Botany, Bangladesh Agricultural University, Mymensingh during November 2001 to April 2002. Early planting influenced the plant height, leaf number, bulb diameter and total dry matter. With the delay in planting time starting from November 7, the yield was chronologically reduced in later plantings. Significantly the highest bulb yield (2.67 t/ha) was recorded when planting was done on November 7 and lowest yield (0.92 t/ha) was obtained from December 22 planted crop. Bulb yield was higher in control plants than those of GA3 treated plants. The interaction effects of planting date and different concentrations of GA3 differed significantly in respect of plant height, number of leaves, bulb diameter and dry weight of roots, leaves and bulbs and yield of garlic.

To evaluate the effects of integrated nutrient management on growth and yield of BARI tomato-14 and soil fertility, a pot experiment was conducted in the net house of the department of Agricultural Chemistry of Bangladesh Agricultural University, Mymensingh during the period from October 2011 to April 2012. The experiment was laid out in a completely randomized design with 11 treatments and 3 replications. Treatments were control, RDCF100, 75% RDCF, 50% RDCF, 75% RDCF + PM2 t /ha, 75% RDCF + RS3 t /ha, 75% RDCF + PHRD, 50% RDCF + PM3 t /ha, 50% RDCF + RS5 t /ha, 50% RDCF + PHRD, PM3 t /ha + RS5 t /ha + PHRD. Among the treatments applied in combination of PM2 t /ha+ 75% of RDCF excelled in growth trends of morphological characters like plant height, number of branches plant- 1, number of leaves plant-1; available soil P and S. But sole application of RDCF100 recorded higher values for almost all morphological characters namely number of branches plant-1, number of leaves plant-1, fruit diameter, fruit weight plant-1 and yield of tomato following the same trend as seen in combined application of CF and PM. Among the plant hormone applied in combination, RDCF75% + PHRD showed the highest plant height. The more number of leaves plant-1, number of branches plant-1, yield and yield parameters as compared to other treatments were also significantly influenced by application of PH. Combined application of 50% of RDCF+RS5 t /ha increased exchangeable soil K. PM3 t /ha+ RS5 t /ha+ PHRD conserved more organic carbon and total soil N. Results showed that the integrated use of PM, RS along with CF increased the availability of nutrients throughout the growth period by maintaining the long term productivity for sustainable production of tomato.

An experiment was conducted in the Horticulture Farm of Agriculture and Forestry University to demonstrate the effects of different fertilizers on the yield and yield parameters of okra (var. Arka Anamika). The experiment was laid out in Randomized Complete Block Design (RCBD) consisting of seven treatments and three replications. The various treatments used in the experiment were goat manure, sesame cake, mustard cake, synthetic fertilizer (NPK), poultry manure, vermicompost and untreated control. The required dose of nitrogen was fulfilled by the fertilizer itself whereas insufficient amount of phosphorous and potassium was fulfilled by addition of single super phosphate and muriate of potash respectively. The fertilizers were applied on the basis of recommendation given by the Nepal Agriculture Research Council (NARC). The effect of poultry manure on number of open flowers and number of fruits at 40 DAS was found superior. The effect of poultry manure on plant height, number of leaves, plant diameter was found superior at 50 DAS. Goat manure produced the superior result on number of open flowers at 50 DAS. Poultry manure on the number of leaves and plant height produced the significant result at 60 DAS. Synthetic fertilizer responded well to number of fruits at 60 DAS. Sesame cake produced the superior results at 70 DAS on number of buds. Poultry manure responded well to all the parameters and produced the yield of 20 qt/ha with the BC ratio of 1.77. This experiment suggests the farmers to use the poultry manure to get the highest economic return. Vermicompost and mustard cake producing the superior and significant yield in this research are not recommended as they have low BC ratio unless effective measures are encouraged to reduce the cost of this fertilizers.

Background and Objective: Unproductive soil has been a major problem to farmers, recent interest in the use of a stable organic manure (biochar) as soil amendment and poultry manure to increase soil fertility is also increasing. Hence, the experiment was conducted to assess the condition of poultry manure and biochar on the growth and yield of tomato. Materials and Methods: A greenhouse experiment was conducted at the Federal College of Forestry Ibadan, using polyethylene bag with 5 kg soil collected at two (2) soils depths, 0-15 cm and 15-30 cm depth at the botanical garden, Federal College of Forestry Ibadan. The experiment was arranged in a completely randomized design (CRD) with four replicates. The treatments used were poultry manure (5t/ha), biochar (10t/ha), mixture of poultry manure and biochar (1:1) and control (no amendment).The tomato seeds (UC82B) were sourced from NIHORT, Ibadan and raised in a germination basket. Data were collected weekly on plant height, collar diameter and number of leaves, 50% days to flowering and yield of tomato plants from two weeks after transplanting (WAT). Data collected were analyzed statistically using ANOVA while means were separated using LSD (p<0.05) where applicable. Results: In 0-15 cm soil, the growth variables (plant height, number of leaves and collar diameter) increased with various treatments used. The highest tomato height was observed with the application of biochar (10t/ha). All the treatments applied affected the number of tomato leaves at all weeks after transplanting (WAT) with poultry manure 5t/ha having the highest number of leaves at 7WAT, while collar diameter was significantly affected by various treatments from 2 to 5 WAT, with the mixture of P.M + BIO (1:1) recording the highest value and the control plot recorded the least values in all weeks. However, in 15-30 cm soil, there was  significant difference in the number of leaves of tomato among all the amended soil from 5 to 7 WAT, the highest tomato leaves were obtained when the soil was amended with poultry manure (5t/ha) and can be compared with other treatments. Interaction of poultry manure and biochar(1:1) and poultry manure 5 t/ha resulted in highest height of tomato plant from 3-7 WAT as compared to the control that had the least value but were not significantly different from the sole application of  biochar 10t/ha. Interaction of poultry manure + biochar (1:1) and poultry manure (5t/ha) gave the highest tomato flowering and fruits. Conclusion: Based on this result, biochar and poultry manure when added to soil, boosted the mineralization of the soil after amendment.
