AbstractA field experiment was carried out to study the effect of spacing and nitrogen level on growth and yield of maize in Parbat from February to July, 2019. The experiment was laid out in two Factorial Randomized complete Block Design (RCBD) comprising of spacing: 60×15 cm and 60×25 cm and nitrogen: 30, 60, 90 and 120 kg/ha level as treatment with three replications. “Arun-2” variety of maize was planted on clay loam and acidic soil (pH 5.3) having medium in total nitrogen (0.15%), medium in soil available phosphorus (48.1 kg/ha), medium in soil available potassium (218.8 kg/ha) and medium in organic matter content (2.92%). Result shows that yield was significantly increased with increment in N-level up to 90 kg N/ha. The grain yield (5.18 mt/ha) was significantly higher at 90 kg N/ha than at 30 and 60 kg N/ha but at par with 120 kg N/ha. Significant effect on grain yield due to spacing was observed. The grain yield (4.11 mt/ha) obtained at spacing 60×15 cm. Moreover, the highest grain yield showed that highest grain yield (4.33 mt/ha) was obtained under 90 kg N/ha plus 60×15 cm spacing. The result revealed that different spacing and nitrogen level significantly affect the plant height and leaf area index. The plant height and leaf area index were significantly high at close spacing (60×15 cm) and at 120 kg N/ha. Likewise, yield attributing characteristics like cob length, cob diameter, number of kernel/rows, number of kernel row, thousand gran weight were the highest at 90 kg/ha but as par with 120 kg/ha at close spacing (60×15 cm). This study suggested that maize production can be maximized by cultivating “Arun-2” maize fertilizing with 90 kg N/ha and maintaining 60×15 cm spacing.

Because of using sulphur free fertilizer, rice crop facing tremendous sulphur (S) deficiency throughout the world as well as in Bangladesh. However, farmers of Bangladesh often overlook the importance of sulphur fertilization on rice yield. Therefore, the present study was conducted to investigate the influence of different levels of sulphur on growth, yield attributes and uptake of N, P, K and S by grain and straw of BRRI dhan41 rice variety. The experiment was laid out in randomized complete block design with three replication and eight treatments including control. The result of the study revealed that the highest plant height, panicle length, filled grain was found in T1 (50% RFD of S) treatment, while the utmost number of effective tiller and straw yield was recorded in T5 (150% RFD of S) treatment. Interestingly, maximum grain yield as well as uptake of N, P, K and S by grain and straw was significantly higher in T6 (175% RFD of S) treatment. The highest grain yield of T6 treatment might be due to maximum nutrient use efficiency. However, in all cases control treatment (T0) gave the worst result. The present study clearly indicates that higher rates (175% of the recommended dose) of S along with other fertilizers may be recommended for better growth and yield of BRRI dhan41 in Bangladesh soil.

Abstract A field experiment was conducted at the first station of the College of Agriculture/University of Al-Muthanna for the agricultural season 2020-2021, with the aim of studying the effect of treatment with salinity stress and kinetin on the growth and yield of the wheat (Triticum aestivum L.) cultivar of Bohooth 22. The experiment was applied by split plates design using a randomized complete block design (R.C.B.D) with three Replicators of 36 experimental units The main units included levels of irrigation water salinity (2.5, 5, 7.5, 10) ds/m, while the secondary units included levels of kinetin (0, 30, 60 Ppm). The results of the statistical analysis showed a significant difference in the salinity of the high irrigation water in most growth traits such as plant height, flag leaf area, number of tillers plant−1, spike length (cm) and number of days to physiological maturity (day) at a rate of (.5473, 14.912, 3.222, 9.176, 143.67) respectively, and the traits of the yield and its components represented by the number of spikes. m2, number of grains per spike, weight of 1000 grains (gm), grain yield (ton ha−1) and biological yield (ton ha−1) at a rate of (300.06, 35.39, 31.60, 3.52, 9.46) respectively, while soaking the seeds with kinetin led to a significant increase in most of the studied traits. Thus, we conclude that salt stress has a negative role on the growth stages of the vegetative plant, and this leads to the reduction of the yield and its components.
