Wheat is one of the most important cereal crop and staple foods in the world. Increase in productivity of wheat by balance nutrient management is one of the most crucial factors. The main objective this study is to assessing the role of micronutrients in improving different components of wheat yield. There are different methods of application such as seed priming, soil application and fortification but foliar application is more beneficial. This is due to response of foliar application has positive and quadrate in nature i.e. the optimum dose of foliar application of zinc for grain yield of wheat was observed as 0.04%. Among treatments of micronutrient alone or combined forms give better results over control. Results have show that micronutrient application substantially improved leaf area index (LAI), leaf area duration, CGR (Crop growth rate), RGR (Relative growth rate), NAR (Net assimilation rate), plant height, spike length, spikelets/spike, grains/spike, test weight, tillers m-2, grain yield, chlorophyll content and biological yield as well as harvest index of wheat. The yield and quality of wheat products improved and boosted by micronutrient applications. Therefore, human and animal health will be protected with the feed of enriched and balanced nutrition of produce as well as it will help in facing the severe global food security.

Field experiment was carried out during the wet season of 2012 at the Teaching and Research Farm of Faculty of Agriculture, Adamawa State University, Mubi (Lat.10° 15II N and Long.13° 16II E, altitude of 696 m above sea level) and a Community based Demonstration Farm in Gombe (Lat.11° 30” N and Long.10° 20” E, altitude of 340 m above sea level). Both locations were situated in the Northern Guinea Savanna agro-ecological zone of Nigeria. The study was carried out to determine the level of correlation between weed parameters, growth and yield attributes of maize as affected by pendimethalin application. Treatments which consisted of six different rates of pendimethalin (1.0, 2.0, 3.0, 4.0, 5.0, 6.0kg a.i.ha-1) + two control checks (weed free and weedy check) were placed in the main plots as main treatment while maize cultivar SAMMAZ 17 was placed in the sub-plots as sub-treatments in a split plot design and replicated three times. Pendimethalin was pre-emergence- applied a day after sowing (DAS). Weed free check plots (control) were kept weed free by regular weeding. Similarly, all agronomic practices were adequately carried out except those under study. Data collected on weed cover score (WCS), weed fresh weight (WFW), weed dry weight (WDW), days to 50% emergence (D50E), crop injury score (CIS), crop vigour score (CVS), establishment count (EC), plant height (PH), leaf area index (LAI), crop growth rate (CGR), relative growth rate (RGR), days to 50% tasseling (D50T), 1000 grain weights (1GWTs) and grain yield (GY) were analyzed using Minitab Version 11 Statistical Software. Results revealed that WCS was significantly higher and strongly correlated with WFW, WDW but was strong and negatively associated with GY of maize in both Mubi and Gombe. D50E, D50T and LAI were positive but contributed weakly to the GY of maize in Mubi. Similarly, D50E, D50T, PH and LAI had same pattern of behavior as the former in Gombe. EC was negative and also contributed weakly to the grain yield of maize in both locations. PH, CVS, CGR, 1GWTs were positive and strongly associated with GY of maize in Mubi. The same trend was also observed for all parameters except PH which though positive it was weakly associated to the final GY of maize in Gombe. Pendimethalin did not posed any significant effect on the post- physico-chemical properties of the soils at the two experimental sites, except in soil-pH, organic carbon, available phosphorus, total nitrogen, magnesium, potassium and sodium in Mubi and available phosphorus, total nitrogen, Calcium, Magnesium and Potassium in Gombe. These soil properties were significantly influenced by rates of soil applied Pendimethalin compared to the control checks.

The experiment was carried out at the research field of the Department of Agronomy of Bangabandhu Sheikh Mujibur Rahman Agricultural University (BSMRAU), Gazipur during December 2016 to April 2017 to investigate the effect of different phosphorus levels (0, 30, 60 and 90 kg P ha-1) on the growth and yield of four selected cowpea genotypes (BARI Felon-1, A-06008, VI046192 and VI034386). The experiment was laid out in a factorial randomized complete block design with three replications. The results indicated that, among the genotype, BARI Felon-1  required minimum days to 1st (96 DAS) and 50% flowering (108 DAS) showing the highest absolute growth rate (0.71 g day-1), crop growth rate (23.69 g m-2 day-1), relative growth rate (0.047 g g-1 day-1), net assimilation rate (1.40 g m-2 day-1), leaf area index (6.68), SPAD value (51.03), seed length (0.71 cm) and breadth (0.54 cm). But the genotype, A-06008 gave the highest grain yield (0.62 t ha-1). Application of phosphorus at 90 kg ha-1 showed the highest leaf area index (6.67), SPAD value (50.98), pod length (14.33 cm), seed length (0.70 cm), seed breadth (0.50 cm) and grain yield (0.34 t ha-1). In terms of growth and yield, the cowpea genotype A-06008 showed the best performance at the phosphorus level of 90 kg ha-1. Bangladesh Agron. J. 2021, 24(1): 25-36

A field experiment was carried out during kharif 2015 at organic farming block of Research Institute on Organic Farming, University of Agricultural Sciences, Bengaluru to study the influence of different levels of jeevamrutha and panchagavya on growth, yield attributes and yield of cowpea in red sandy loam soil. The results revealed that application of jeevamrutha at 1000L ha-1 and panchagavya at 7.5% significantly influenced growth parameters like plant height, number of branches, number of leaves, leaf area and leaf area index. Interaction effect of jeevamrutha and panchagavya was significant in enhancing the grain yield of cowpea besides improvement in yield attributes like number of pods per plant, length of pods, pod weight, number of seeds per pod, seed weight per plant and 100 seed weight. Nodule characteristics – total and effective number of nodules as well fresh and dry weight of nodules was also significantly influenced by jeevamrutha and panchagavya application at different levels and also due to their interaction. Liquid organic formulations – jeevamrutha and panchagavya are effective in producing higher grain yield in cowpea.

An experiment to find out the wheat growth as affected by foliar application of potassium Sulphate (K2SO4) on different growth stages under rainfed conditions was conducted at the Agricultural Research Institute, Dera Ismail Khan, Pakistan. Potassium doses viz. 0, 12, 18, 24, 30 and 60 kg ha-1 were applied in foliar form at tillering, booting and heading stages of wheat. The course of study revealed that foliar application of K2O in booting stage produced maximum leaf area index (LAI), leaf area duration (LAD), crop growth rate (CGR), net photosynthesis rate (NPR) and grain yield, while its application at heading stage produced maximum net assimilation rate (NAR). Among different doses, the application of potassium at the rate of 60 kg ha-1 potassium at the rate of 60 kg ha-1 produced maximum growth and yield and its components during two consecutive cropping seasons of wheat crop while weed density (m-2), relative weed density (%), fresh weed biomass (g m-2) and dry weed biomass (g m-2) influenced non-significantly for both the years. These findings suggest that foliar application of potassium sulphate @ 60 kg ha-1 along with recommended dose of nitrogen (120 kg ha-1) and phosphorus (90 kg ha-1) is the most suitable for successful wheat production under rainfed conditions.

A field experiment was conducted during the summer, 2014 at College of Agriculture, Vellayani, Kerala to evaluate the influence of irrigation levels, nitrogen stress and method of application of fertilizers on growth and yield of yard long bean. The experiment consisted of four levels of irrigation, two levels of nitrogen and two methods of application. The results indicated that daily irrigation at 10 mm depth and recommended dose of nitrogen (30 kg ha-1) recorded superior values for growth parameters viz., functional leaves per plant and leaf area index The major yield attributes like number of pods per plant and pod yield per plant and total pod yield were not influenced by levels of irrigation and nitrogen indicating that irrigation once in three days at 20 mm depth and nitrogen level of 22.5 kg ha-1 is sufficient for yard long bean. Soil and foliar application of nitrogen and potassium recorded superior growth characters, however, the yield was superior when the recommended dose of nutrients were supplied as soil application. Increasing irrigation interval to three days and imparting N stress did not result in any reduction in gross income and net income while, a higher benefit: cost ratio was noted in irrigation at wider intervals. Soil application of nutrients recorded higher gross income, net income and BCR compared to soil + foliar application.

Randomized Block Design

Background: Blackgram [Vigna mungo (L.) Hepper] is one of the most important cultivated legume crops with high nutritive value and agricultural importance. The productivity of blackgram is not adequate to meet the domestic demand of the growing Indian population. Consequently, there is an urgent need for enhancement of productivity through proper agronomic practices. With this background, a research experiment was conducted in a farmer’s field at Pudhupalayam, Coimbatore to investigate the effect of foliar application of PPFM, plant growth regulating compounds and nutrients on growth, yield attributes, yield and economics of irrigated blackgram. Methods: A field experiment was laid out in randomized block design with three replications during 2019 (kharif and rabi) season. The treatments include 100% recommended dose of NPK along with foliar application of diammonium phosphate (DAP), brassinolide (Br), salicylic acid (SA) and pink pigmented facultative methylotrophs (PPFM) with different concentration (1%, 2%, 1 ppm, 2 ppm, 50 ppm, 100 ppm, respectively) in addition to control. PPFM and PGRs were sprayed at 30 and 45 days after the sowing of blackgram. Result: The experiment results of the two seasons study revealed that the application of 100% RDF + PPFM @ 2% recorded higher growth characters viz., plant height (cm), number of branches plant-1, leaf area index and yield attributes viz., number of pods plant-1, number of seeds pod-1, pod weight (g), pod height (cm), 100 seed weight (g) and yield viz., grain yield (kg/ha), straw yield (kg/ha) and harvest index (%). As well as the same treatment recorded higher net return and B:C ratio. Correlation and regression analysis also indicated that the yield attributes had a positive impact on the grain yield with a magnitude of 1.91 and 1.67, respectively. Therefore, application of 100% RDF+2% PPFM spray can be recommended as the best technology to improve the yield and economics of blackgram.

A field study was conducted during the Rabi season of 2009-2010 in the research field of Bangladesh Council of Scientific and Industrial Research (BCSIR), Dhaka. Six levels of GA3, viz. 0, 30, 50, 70, 90 and 110 ppm were sprayed at 18 days after sowing (DAS). GA3 treatments significantly increased plant height than the control plants. GA3 with 30 to 90 ppm significantly increased number of branches and leaves, leaf area, leaf area index (LAI), leaf dry matter and total dry matter at different growth stages. GA3 at 30 to 70 ppm gradually increased crop growth rate (CGR), net assimilation rate (NAR) and relative growth rate (RGR) and declined advanced growth stages. Number of dry pods /plant, number of seeds /pod, 1000 seed weight, fresh fodder, fresh pod, dry seed yield and harvest index also significantly increased. Positive significant correlations were found among growth parameters and as well as yield contributing characters. Asiat. Soc. Bangladesh, Sci. 43(1): 49-60, June 2017
