Response of yield, nitrogen use efficiency and grain protein content of wheat (Triticum aestivum L.) varieties to different nitrogen levels

A field experiment was carried out in order to investigate the response of nitrogen use efficiency and yield of two wheat varieties to different nitrogen levels. The wheat varieties, viz. Bijoy (V1) and Prodip (V2) were tested under 4 levels of nitrogen (N0 = 0 kg N/ha, N1 = 60 kg N/ha, N2 = 120 kg N/ha and N3 = 180 kg N/ha) where wheat varieties assigned in main plot and nitrogen treatments in subplot. Grain yield was increased with increasing rates of nitrogen. Maximum grain yield (3.85 kg/ha) produced by the variety Prodip when N applied @ 180 kg/ha and minimum (1.15 kg/ha) by the variety Bijoy under control treatments. Interactions of two variety and nitrogen levels; N uptake by grain and straw increased with increasing nitrogen levels. Highest N uptake by grain (90.60 kg/ha) and straw (25.53 kg/ha) were observed from the variety Prodip with 180 kg N/ha. Highest (38.66) N use efficiency (NUE) was noticed in Prodip when received 60 kg N/ha. Grain protein (%) also showed maximum value (14.29) when Prodip fertilized with 180 kg N/ha. Between two varieties, Prodip was the best performer with 180 kg N/ha due to maximum nitrogen content and upake in grain and straw, maximum N use efficiency fertilizer recovery percentage and grain protein

Impact of Foliar Application of Zinc and Zinc Oxide Nanoparticles on Growth, Yield, Nutrient Uptake and Quality of Tomato

Appropriate foliar application of zinc (Zn) and zinc oxide nanoparticles (ZnO-NPs) is important for the proper growth and yield of tomato. However, the effects of foliar application of Zn and ZnO-NPs were not well-studied on tomato production. A pot experiment was conducted at glasshouse (8D) conditions under the Faculty of Agriculture, Universiti Putra Malaysia (UPM) to evaluate the effectiveness of Zn and ZnO-NPs on growth, yield, nutrient uptake, and fruit quality of tomatoes and to compare between the Zn nutrient and ZnO-NPs. Treatment combinations were 14 viz. T1 = 0 (control), T2 = 1500 ppm (mg/L) Zn nutrient, T3 = 2000 ppm (mg/L) Zn nutrient, T4 = 2500 ppm (mg/L) Zn nutrient, T5 = 75 ppm ZnO nanoparticle, T6 = 100 ppm ZnO nanoparticle, and T7 = 125 ppm ZnO nanoparticle along with two tomato varieties. The experimental design was a split plot with four replications. Results indicated that foliar application of 100 ppm ZnO-NPs performed best in terms of growth parameters, physiological traits, yield attributes, yield, and quality traits of tomatoes. The same treatment (100 ppm ZnO-NPs) contributed to attain the highest nutrient uptake. Recovery use efficiency of Zn was highest with foliar application of 75 ppm ZnO-NPs. The highest yield increment (200%) over control was from foliar sprayed with 100 ppm ZnO-NPs. Comparing the two varieties, MARDI Tomato-3 (MT3) showed better than MARDI Tomato-1 (MT1). As is appears from the results, foliar application of zinc oxide nanoparticles was more efficient than conventional zinc fertilizer. Therefore, the foliar sprayed with 100 ppm ZnO-NPs can be suggested to improve quantity and quality of tomato in glasshouse soil conditions
