Abstract Three rice varieties (Goura, Chakhao and Local) were grown during two seasons 2019-2020, aimed to assessment of different levels of spraying of phenylalanine on performance of the grain yield components in different rice varieties. The selected three varieties (sub plots) were grown under the influence of four levels of phenylalanine spraying (main plots), included amino acid treatments occupied the main plates 50, 100 and 150 mg.L-1 as well as the control treatment (spraying distilled water only), the experiment applied in split plots arrangements in RCBD with three replications. The results showed a significant superiority of the Goura genotype selected by giving the highest averages in plant height, total grains number per panicles, 1000 grains weight, grain yield, Biological yield, percentage of harvest index and tillers number plant, that reached to 118.47 cm, 144.25 grains.panicl-1, 23.44 g, 6.70 tons.hectare-1, 12.06 tons.hectare-1,54.82% and 18.40 tillers.plant-1 respectively, while the genotype significantly superior to Local Selected by giving the highest averages in the leaves content of total chlorophyll pigments SPAD, which amounted to 39.13 SPAD. The spraying of the amino acid phenylalanine at a concentration of 50 mg.l-1 was significantly superior by giving the highest averages in the indicators of vegetative growth, yield and its components.

Although,chickpea isnitrogen fixing crop but water scarcity under rain-fed condition reduces its nodulation process severely and nutrients use efficiency too. An experiment was carried out regarding the combined effect of nipping as well as foliar applied fertilizers on yield and yield components of chickpea under rain-fed conditions. Nipping and foliar application of nutrients significantly improved number of pods plant-1, biological yield (kg ha-1), harvest index (%) and final grain yield (kg ha-1). However, non-significant influence was seen in 1000-grain weight and number of grains pod-1. Foliar application of N PK (20:20:20) @2.5 kg ha-1 × nipping was found to be the best interaction among others which significantly increased number of branches plant-1 (11.30), number of pods plant-1(115.36), plant height(59.48cm) and grain yield(2338.9 kg ha-1) as compared to the control treatment. Nipping along with foliar application of NPKcan be practiced in chickpea for higher profitability.

An experiment was conducted in the farmer’s field at the Moddho Jutkhali village, Subornochar, Noakhali, a salinity affected area of Bangladesh to investigate the effect of variety and gypsum fertilizer on the yield of transplant aman rice under salinity condition during July to December, 2017. The experiment was laid out in a two factor split-plot design with three replications consisting of three aman rice varieties viz., Swarna (V1, an indian variety adapted to that locality), BRRI dhan52 (V2) and Binadhan-7 (V3) and three levels of gypsum fertilizer viz., 0, 75 and 150 kg gypsum ha-1. Yield components and yield of transplant aman rice were significantly influenced by variety, level of gypsum and their interactions. Among the varieties, Swarna produced the tallest plant height (126.7 cm), highest number of grains panicle-1 (76.30), weight of 1000 grains (25.80 g), grain yield (5.44 t ha-1), straw yield (7.07 t ha-1), and biological yield (12.51 t ha-1) while Binadhan-7 showed lowest values of these respective parameters but number of total tillers hill-1 (9.99) and number of effective tillers hill-1 (8.94) were maximum in Binadhan-7. Among three gypsum levels, most of the yield contributing characters showed highest values for 150 kg gypsum ha-1 that’s why grain yield was also highest (5.32 t ha-1) for this treatment. On the other hand lowest grain yield (4.92 t ha-1) was found when no gypsum was applied. In case of treatment interaction, highest number of grains panicle-1 (80.23) and highest grain yield (5.69 t ha-1) were produced when Swarna was cultivated with 75 kg gypsum ha-1 while lowest values of grain, straw and biological yields (4.36, 5.11 and 9.47 t ha-1, respectively) were found when Binadhan-7 was cultivated without applying any gypsum. Therefore, it can be concluded that the variety Swarna with 75 kg gypsum ha-1 can be practiced for the cultivation of transplant aman rice in the salinity affected area of Noakhali, Bangladesh to obtain the highest grain yield.

There is conflicting informations regarding the advantages of planting of stock seed (SS) over Extension Seed (ES) classes. An experiment to study the effect of different seedclasses on grain yield and yield components of five rice varieties was carried out at two locations i.e. Sukamandi and Muara Field Station during the wet and dry season of 2009. The treatment consisted of five rice varieties, namely: Ciherang, Mekongga, IR64, Cigeulis and Situ Bagendit, and their respective seed classes: namely breeder seed, foundation seed, stock seed and extension seed. The experiment was arranged in a split plot design with three replications, where rice varieties were as main plots and seed classes as sub plots. Variables to be evaluated consisted of: quality of seed before sowing, plant growth, yield components and grain yield. Performance of the observed variable of each rice variety derived from four different seed-classes in each location and planting season were not significantly different. Differences of seed classes only affected the percentage of seed purity. There was no significant difference on the grain yield and the seed yield obtained from different seed classes of each variety. These results disprove the belief that the higher seed class the higher productivity, which was found to be a wrong perception. Seed certification is designed to maintain the genetic purity of variety and not to increase the productivity.

A pot culture and a field experiment were conducted with cyanobacteria in presence and absence of different levels of urea to evaluate their effects on growth and yield of rice cv. BRRI Dhan 28, 29 and 36 during Boro season of 2007. The treatments were T1 (control), T2 (only cyanobacteria), T3 (recommended doses of urea - 60 kg N/ha), T4 (45% recommended doses of urea + cyanobacteria), T5 (65% recommended doses of urea + cyanobacteria) and T6 (85% recommended doses of urea + cyanobacteria).The maximum values for different growth, yield and yield components (plant height, number of productive tillers/hill, panicle length, number of grains/panicle, 1000-grain weight, and grain, straw and biological yield) were observed in BRRI Dhan 29 under T6 (85% recommended doses of urea + cyanobacteria) and lowest was observed in BRRI Dhan 28 under T1 (neither urea nor cyanobacteria). Uses of cyanobacteria increased the yield of Boro rice varieties and decreased the use of urea by 15-20%.

Grain Number Per Panicle

The genetic basis for three grain yield components of rice, 1000 kernel weight (KW), grain number per panicle (GN), and grain weight per panicle (GWP), was investigated using restriction fragment length polymorphism markers and F4 progeny testing from a cross between rice subspecies japonica (cultivar Lemont from USA) and indica (cv. Teqing from China). Following identification of 19 QTL affecting these traits, we investigated the role of epistasis in genetic control of these phenotypes. Among 63 markers distributed throughout the genome that appeared to be involved in 79 highly significant (P < 0.001) interactions, most (46 or 73%) did not appear to have “main” effects on the relevant traits, but influenced the trait(s) predominantly through interactions. These results indicate that epistasis is an important genetic basis for complex traits such as yield components, especially traits of low heritability such as GN and GWP. The identification of epistatic loci is an important step toward resolution of discrepancies between quantitative trait loci mapping and classical genetic dogma, contributes to better understanding of the persistence of quantitative genetic variation in populations, and impels reconsideration of optimal mapping methodology and marker-assisted breeding strategies for improvement of complex traits.

Abstract The experiment was carried out according to the randomized complete block design (R.C.B.D) and the arrangement of split-split plot with three replications, at the Field Crops Research Station of the Agricultural Research Department - Abu Ghraib during the spring season for the years 2019 and 2020. With the aim of studying the effect of amino acids, planting dates and their effect on some of the yield characteristics and its components for three varieties of maize in the spring season. Planting dates (March 15, March 25 and April 5) occupied the main plots, while amino acids and the control treatment (proline, arginine, and distilled water) occupied the sub-plot, whereas the varieties (Rabi, Baghdad 3 and Fajr 1) occupied the sub-sub-plot, and the most important results were summarized as follows:The two cultivars, Rabi and Fajr-1, achieved a significant increase in most of the yield characteristics and its components for the seasons. The addition of the amino acid proline also led to a significant increase in most of the studied traits (the number of grains in ear, weight of 500 grains, total grain and biological yield, and harvest index), planting dates also have a significant effect on most of the studied traits. The first date (15/3) recorded increase in the number of grains per ear, the weight of 500 grams, and the grain and biological yield. The plants of the Rabi variety when cultivated on March 15 th and sprayed with the amino acid proline achieved the highest average for the grain yield, which reached 7.48 ton. ha-1 for spring 2019.
