Abstract: An experiment was conducted at the Agronomy Field Laboratory, University of Rajshahi, Bangladesh during the period from November, 2019 to May, 2020 to study the effect of different levels of sulfur and zinc fertilizer on the yield and yield components of Boro rice. The experiment was laid out in a Randomized completely Block Design (RCBD) with three replications. It was consisted of two factors: (i) sulfur levels viz 0 kg ha-1, 6 kg ha-1, 12 kg ha-1 and 18 kg ha-1 and (ii) zinc levels i.e. 0 kg ha-1, 0.5 kg ha-1, 1.5 kg ha-1 and 2.5 kg ha-1. The treatment that contained 18 kg of sulfur per hectare produced the highest plant height, number of grains per panicle, and thousand grains weight, according to the findings of this study. The highest grain and straw yield were found when the field was treated with 18 kg sulfur ha-1. Among the zinc levels, 2.5 kg zinc ha-1 produced the highest plant height, total tillers, effective tillers, grains panicle-1 and yield. After application of 2.5 kg zinc ha-1in the field, the grain and straw yield was showed highest result. So, it could be concluded that the maximum grain yield was gained when the field was fertilized with 18 kg sulfur ha-1 and 2.5 kg zinc ha-1.

Abstract: Chickpea is one of the most importance sources of protein all over the world, yet its productivity is often constrained by poor soil fertility, water scarcity and inefficient nutrients management, particularly in nitrogen management. A field experiment was carried out from November 2021 to December 2022 to find out the response of different chickpea cultivars to foliar application of nitrogen. This research work was organised in RCBD considering three varieties of gram viz. Bengal gram, BARI Chola-5, BARI Chola-9 and four nitrogen treatments were tested: N0 (control, no nitrogen), N1 (full recommended basal dose), N2 (half basal + 1% foliar spray at flower initiation) and N3 (half basal + 2% foliar spray at flower initiation). Only N2 and N3involved foliar application, allowing evaluation of its effect on chickpea growth and yield. This experiment revealed that BARI Chola-9 (V3) produced the highest number of pod (44.33), number of seeds per pod (2.11), 1000 seed weight (196.03g) and seed yield (2.42 t ha-1). On the other hand, foliar application of nitrogen significantly influenced the characters. In case of 2% foliar nitrogen application treatment (1/2 basal dose +1/2foliar spray at pre flowering stage) showed the highest no. of pod (42.26), no. of seed (2.04), 1000 seed wt. (136.41g) and seed yield (1.95 t ha-1). Observing the interaction effect, it was found that maximum pod (45.66), no. of seed (2.33), 1000 seed wt. (197.13g) and seed yield (2.55 t ha-1) were recorded from V3N3. Overall, BARI Chola-9 gave maximum yield when 2% nitrogen foliar spray was applied with basal dose at flowering stage of chickpea.
