The purpose of this study was to determine the effect of seed rate on the growth and yield attributes of the wheat crop (Triticum aestivum L.) variety Mazar-99 under the agro-climatic conditions of Takhar province, Afghanistan. The experiment was implemented at the research farm of Agriculture Faculty of Takhar University in winter seasons of 2018-2019 with the specific objective of finding out the effect of five seeding rates as the treatment on growth and yield parameters of Mazar-99 variety of wheat. Randomized Complete Block Design (RCBD) was selected as an experiment design with 4 replications and 5 seeding rates viz. 80, 100, 120, 140 and 160 kg/ha made up treatments. Data on growth and yield parameters were collected and analyzed using Analysis of Variance (ANOVA) for Randomized Complete Block Design (RCBD). The result obtained from the current study reveal that all growth and yield characters were remarkably affected by seeding rate and seed rate of 100 kg per hectare of wheat variety Mazar-99 performed better with respect to different growth and yield parameters such as spike length, number of tillers, number of spike at each plant, leaf area, a total of spikelets per spike and stem girth, grain number/spike, the weight of spike, the weight of grain per spike, grain crop yield, straw crop weight, 1000-grain weight, and biological yield. Whereas 80 and 120 kg/ha were the second-best seeding rates after the 100 kg/ha. However, 160 kg/ha seed rate showed only superiority in plant height, but 140 kg/ha did not show any special superiority in any growth and yield characteristic evaluated in Takhar agro-climatic condition. Thus, a seeding rate of 100 kg per hectare could be recommended to the farmers for better wheat production in Takhar agro-climatic situation in North-Eastern Afghanistan.

Significant Area

Wheat is one of the most important cereal crops of the world and is a staple food for about one third of the world’s population. Despite the significant area of wheat production in the country, the mean national yield 1.3 t ha-1 is 24% below than mean yield for Africa and 48% below than global mean yield. A field experiment was carried out at Senegal and Selmamer during 2014 cropping season to determine the effects of sowing methods and seed rate on yield of bread wheat (Triticum aestivum L.). Treatments were two sowing methods namely row planting and broadcasting with six  Seed rate (kg/ha): 125, 150, 175, 200, 225 and 250 kg/ha.The experimental was laid in randomized complete block design (RCBD) with thee replications. The study result depicted that sowing method and seed rate had brought significant effect on the   yield of bread wheat. The maximum grain yield of 3.9 t ha-1 and the minimum 2.7 t ha-1 were obtained from seed rate of 125 kg ha-1 and 200 kg ha-1 respectively. And the maximum grain yield of 3.5 t ha-1 was obtained from row planting and the least 3.13 t ha-1 was recorded from broadcast method; from these output we can conclude that, using of seed rate of 125 kg ha-1 and row planting is advisable for bread wheat production in the Senegal and Senmamer kebeles and their vicinities to increased wheat production and productivity.

ABSTRACT<br /><br />Indonesia is one of the largest wheat importers. Suitable environmental condition for wheat needs to be studied if wheat is going to be widely cultivated in Indonesia. The adaptability of wheat grown in various climates and altitudes is one of the important aspects. The objective of this experiment was to study the quantitative and morphological character of wheat grown in middle land (540 m asl) in Bogor, West Java. The experiment was arranged in randomized complete block design with three replications. Wheat genotypes used were three national varieties (Nias, Selayar, and Dewata), four new improved varieties (Guri 3 Agritan, Guri 4 Agritan, Guri 5 Agritan, and Guri 6 Unand), and one introduced genotype (SBD). Data were collected for several quantitative variables and seventeen morphological characters based on UPOV descriptor. The result showed that wheat growth was restricted in Bogor. Genotype determined plant height, leaf number, ear length, root length, number of spikelet, harvest time, seed weight, number of tillers, and plant biomass. Based on ear length, grain weight, and plant biomass, Guri 3 Agritan had the highest production than the other genotypes.<br /><br />Keywords: diversity, genetic relationship, high temperature, introduced genotype, phylogenetic<br /><br />

A 2-year field experiment was conducted at Panwari village of Agra district (U.P.) during rabi season of 2015-16 and 2016-17 to study the response of wheat (Triticum aestivum L) to different levels of nitrogen and sulphur. Four levels each of nitrogen (0, 40, 80 and 120 kg ha-1) and sulphur (0, 10, 20 and 30 kg ha-1) were evaluated in randomized block design with three replications. The results revealed that the application of 120 kg N ha-1 recorded the significantly highest plant height (92.1 cm) and test weight (40.9 g). The highest yields of grain (5.57t ha -1 ) and straw (6.86t ha-1) were recorded with 120 kg N ha-1 and the grain and straw yield increments were to the extent of 44.6 and 42.6%, respectively. The sulphur level of 30 kg ha-1 recorded the highest grain (5.13t ha-1) and straw (6.36t ha-1) yield being statistically at par with 20 kg S ha-1 but significantly higher than 10 kg S ha-1. The results indicated the superiority of combined use of N and S in improving the productivity of wheat to compared to application of N alone. The content and yield of protein were also increased with N application and maximum values were recorded with 120 kg N ha-1. There was a significant increase in protein content and yield of wheat grain and maximum values were recorded with 30 kg S ha-1. A phenomenal increase in N, P and S uptake by wheat grain and straw was recorded due to increasing levels of N and S up to 120 kg and 30 kg ha-1, respectively. The available N and S reduced in the control plot in post harvest soil over their initial values. The higher values of available N (222.5 kg ha-1) and S (19.4 kg ha-1) were recorded with 120 kg N ha-1 and 30 kg S ha-1, respectively.

An experiment was conducted to study the screening of wheat (Triticum aestivum L.) genotypes for drought tolerance under laboratory condition during2018 at Department of Seed Science and Technology, College of Agriculture, Vijayapura. The experiment was carried out in a factorial Complete Randomized Block Design with seven treatments replicated three times. Twenty six wheat genotypes were screened for drought tolerance using 0, 15, 30, 60 per cent polyethylene ethylene glycol 6000 (PEG6000) and 1, 2, 5 per cent mannitol solutions. Data were recorded on various seedling parameters like germination percentage, root length, shoot length, seedling dry weight and seedling vigour index. The seedling traits showed a decreasing trend in response to increased concentrations of PEG6000 and mannitol. Wheat genotype DBW-110 (98.70 %) and C-306 (92.50 %) were found to be the best genotype for screened based on germination percentage at 15 per cent PEG6000 and 5 per cent mannitol. Wheat genotypes HI-1620 (6.7 cm) and NIAW-3212 (4.5 cm) produced maximum root length, respectively at higher concentrations of PEG6000 and mannitol. The genotype HI-1620 (6.4 cm, @ 15 %; 5.4 cm, @ 5 % mannitol) showed maximum shoot length. The genotype HD-2733, DBW-14, DBW-88 showed highest reduction of seedling parameters observed at increase in osmotic stress condition.
