The experiment was conducted to clarify the growth and yield response of two rice cultivars, BR55 and BR43 under salt stress. Six different concentrations of NaCl viz 50, 100, 150, 200, 250 and 300 mM and distilled water (control) were applied on the rice cultivars which were grown under pot culture condition. Growth parameters like plant height, tiller number, leaf number and leaf area were negatively affected by salinity in both cultivars. Salt stress caused a significant reduction in yield in both cultivars of rice. Growth reduction was higher in BR43 than in BR55.The reduction in yield and yield parameters were found to be lower in BR55 than those in BR43. The results obtained in the present study suggest that BR55 showed higher salt tolerance than in BR43. Jahangirnagar University J. Biol. Sci. 7(2): 1-12, 2018 (December)

Abstract The study was conducted to evaluate the growth and yield response of M20 with the application of Nostoc and to determine the ideal combination of inorganic fertilizer and Nostoc. Based on the result of the study, in terms of growth parameters; application of 3 g Nostoc with 1/2 RRIF gave the best response among the treatment in plant height, while application of 3 g Nostoc with 3/4 RRIF was the best treatment when it comes to days to flowering. Furthermore, the application of full RRIF was the best in terms of chlorophyll content. In yield parameters, the application of 3 g Nostoc with 1/4 RRIF gave significance response to grain yield and biomass. While the application of no Nostoc with 1/4 RRIF had the heaviest 1000 grain weight. For the number of tillers per plant (14.7), the application of 3 g Nostoc with 3/4 RRIF gave the best response among the treatments. And for the number of filled grains, rice grown without Nostoc but fertilized only with 1/2 RRIF had the most number of filled grain. Overall, Nostoc treatment did not significantly alter the response of M20 based on all agronomic parameters tested in the study.

The present study was carried out at ICAR -Central Potato Research Station, Gwalior during 2012-13 to assess the effect of dormancy breaking chemicals, their dip duration and microtuber size on growth and yield parameters. The three different size >4-6mm, >6-8mm and >8mm of variety Kufri Sindhuri were given dip treatment with six types of growth regulators/ dormancy breaking chemicals viz 1ppm gibberelic acid, 0.5 ppm gibberllic acid, 1% thiourea, 0.5 % thiourea, 1ppm gibberllic acid + 1% thiourea and 0.5 ppm gibberllic acid + 0.5 % thiourea along with water control for 30 min, 45 min and 60 min. All the treatments exhibited better growth and yield parameters over water control but significantly best at 5% was 0.5 ppm gibberllic acid treatment for growth parameters and 0.5 ppm gibberllic acid + 0.5 % thiourea treatment for yield parameters. All the dip duration 30 min, 45 min and 60 min had not significant at 5% level effect for both growth and yield parameters. The larger sized micro-tuber (>8 mm) showed significantly superior plant emergence, plant height, number of compound leaves per plant, number of stems per plant both at 50 and 75 days after planting followed by 4-8 mm grade and <4 mm grade micro-tubers. Similar trend was observed for all the yield parameters. The overall mean finding indicates that micro-tubers treated with 0.5 ppm gibberllic acid in combination with 0.5 % thiourea gave highest yield (226.0 q/ha tuber), among micro-tuber size of >8mm (295.0 q/ha tuber) and among dip duration 30 min (206.67q/ha) and 45 min (210 q/ha) resulted in significantly higher yield parameters under nucleus seed production in in vivo conditions of central India.

1. Cereal plant density affects yield and growth parameters of fundamental importance. An experiment is described in which growth and development, and yield and yield components of barley grown over a wide range of density were examined.2. Four varieties of barley—Proctor, Plumage-Archer, Domen, and Moore—were grown at densities approximately equivalent to 35, 70, 140 and 280 lb/acre. Density was found not to affect seedling establishment or plant survival, but there was a variety effect on seedling establishment.3. Varietal differences were seen in maximum tiller number, and the percentage of tillers surviving to form ears. These differences were most marked between the six-row variety and two-row varieties. The effect of increasing density was to increase the maximum tiller number, but this was followed by different rates of tiller death until early June, after which there was no further compensation for tiller number. Ear emergence and ear number were affected both by variety and density.

Dry seeds of six faba bean varieties (Sakha 1, Nubaria 2, Nubaria 3, Giza 3, Giza 716 and Giza  843) were irradiated with low doses of gamma rays (20, 40, 60, 80, 100 and 200 Gy). Treated seeds and control seeds were grown for two seasons. Results revealed that doses below 100 Gy increased morphological  growth parameters as well as some yield parameters. The most effective dose varied in different faba bean varieties. Higher doses above 100 Gy were detrimental to plant growth and yield. The variation in ISSR profiling in response to g-irradiation treatments in M2 was detected using seven ISSR primers. The seven primers produced 81 bands including 75 polymorphic bands and 6 unique bands. The unique bands were scored in var. Nubaria 3 by the doses (20, 80 and 100 Gy), var. Giza 3 by the doses (20 and 60 Gy) and var. Nubaria 2 by the dose 200 Gy. The two varieties Nubaria 3 and Nubaria 2 showed higher numbers of polymorphic bands (225, 191) respectively compared to other varieties. Polymorphic information content (PIC) was estimated for each primer and ranged from 0.193 for primer 807 to 0.31 for primer 834 with a mean of 0.259.

A pot experiment was carried out at the Laboratory of Department of Agronomy, Hajee Mohamad Danesh Science and Technology University (HSTU), Bangladesh during 2016 to evaluate the response of maize varieties at germination and seedling growth stages under salt stress. The seeds of the BARI (Bangladesh Agricultural Research Institute) developed four maize varietiesviz.Barnali, Khoi Vutta, Mohor and BARI Maize 5 were placed in plastic pots (each of 25 cm length and 12 cm width) on sand bed irrigated with tap water (control), 100 and 200 mM NaCl salt solutions. It was replicated in thrice with completely randomized design (CRD). Salinity stress significantly affected the germination characters and seedling growth parameters of maize varieties. The germination percentages (GP) and germination rate (GR) reduced significantly with increasing salinity, and the variety Khoi Vutta showed the highest GP and GR followed by Barnali and Mohor showed the lowest GP and GR followed by BARI maize 5. Under high salinity level, seedling growths characteristics like shoot and root lengths, fresh and dry weight of shoot and roots reduced remarkably in the variety Mohor indicating salt susceptible while the minimum reduction of the aforementioned traits was observed in the variety Khoi Vutta demonstrating high salt tolerant variety. The studied varieties can be ranked on the basis of salt tolerance as Khoi Vutta > Barnali > BARI Maize 5 > Mohor from the experiment.

A field experiment was conducted during rabi season of 2019 at farmer’s field in Panruti near Cuddalore district (Tamil Nadu) to study effect of organic manures as INM component on growth, yield and quality of chilli (Capsicum annuum L.) in a randomized block design. The treatments consisted of recommended dose of fertilizers at two levels (160:60:30 and 120:45:22.5 kg NPK ha-1) and organic manures (20 t FYM ha-1, 50 kg Bio ash ha-1, 5 t press mud granules ha-1, 20 kg Sea weed extract granules ha-1 and 5 t neem cake ha-1) and replicated three times. The growth and yield parameters of chilli were significantly influenced due to application of organic manures. Among the treatments, 75% RDF + 20 t FYM + 20 kg Sea weed extract granules + 5 t neem cake ha-1 (T8) exhibited better performances of growth and yield parameters of chilli cv. Indus 13. The maximum values of growth parameters such as plant height, leaves plant-1, branches plant-1, canopy volume, chlorophyll content in the leaves and net photosynthetic rate were observed in this treatment (T8). The yield parameters such as days to first flowering, days to 50% flowering, flowers plant-1, fruit set, fruits plant-1, fruit length, fruit girth, pericarp thickness, pulp seed ratio, single fruit weight, total fruit yield (28.18 t ha-1) and quality parameters like capsaicin content (0.76%) and ascorbic acid content (171.3 mg g-1) were highest in this treatment (T8) suggested this is the best integrated nutrient management combination for chilli. Application of 100% RDF (160 : 30 : 30 kg ha-1) proved inferior in respect of growth and yield of chilli.

Soils fertility declining limits agricultural production in Togo where maize (Zea mays L.) is most cereal cropping and base staple food. Currently, mineral fertilizers are beyond the reach of farmers due to high price and limited availability. This study assessed the response of household urban wastes compost to the growth and yield of maize Ikenne variety. Experiments were performed in rainy season of years 2018 and 2019 at Teaching Research and Demonstration Farm of Agronomy School in University of Lome, Togo. Agronomic trials were set at randomized in complete block design with three replications, where control plots, compost plots at different doses and mineral fertilizers plots constituted the treatments. The growth parameters, including plant height, stem girth, leaf area and number of leaves per plant, were measured at the milky maize stage. The yield parameters, including length and girth of cob, thousand grains weight, grain yield and straw yield, were collected at harvesting. Data were statistically analyzed. The results showed three distinct homogeneous groups of treatments both for growth and yield parameters. Plots treated with compost at 30 t ha-1 and 40 t ha-1 constitute the best group, which differs significantly from the second group formed by plots treated with compost at 10 t ha-1 and 20 t ha-1 and mineral fertilizer plots. Control treatments constitute the last group. Growth and yield parameters values increase with compost dose. Far from being used alone in place of mineral conventional fertilizer, integrated fertilization based on combination of mineral fertilizer and compost of household urban wastes will investigated in maize cropping in southern Togo for optimal compost dose to recommend.

Abstract Purpose Salinity pose severe threat to cultivation as it drastically affects the plant sustainability and yield. The intended aim of current consensus is to assess effects of sodium silicate and salicylic acid on wheat genotypes (slat tolerant and salt sensitive) grown under salt. Methods This experiment was designed to check the effect of silicon on wheat varieties, so four different wheat genotypes named as (Umeed, Rasco, Zarghoon and Shahkaar) were grown in hydroponics under saline and normal environment. Sodium silicate and salicylic acid were applied on all varieties to determine the slat tolerance ability. Plants were harvested at maturity and different physical and chemical aspects were recorded. Results To assess the salt stress on growth and yield of wheat genotypes. Wheat grown in saline conditions with sodium silicate supplementation showed improvement in all growth parameters as compared to the plants grown under salt stress without silicon supplementation. Higher contents of potassium were observed in plants grown under salt stress with silicon supplementation however, potassium concentration was found less in salicylic acid treatment and control under salt stress. Sodium concentration was found higher under salt stress but sodium silicate application reduced Na+ uptake under salt stress. Significance increase in K+ : Na+ ratio in roots enhance the translocation which in turn elevates salt tolerance ability. Among wheat varieties potassium uptake was quite high in Umeed and Rasco as compared to Zarghoon and Shahkar. Conclusion Based on current results it can be deduced that application of sodium silicate on different wheat varieties mitigated Na+ toxicity by elevating K+: Na+ ratio and net translocation rate in salt stressed plants.

The availability of micronutrients in the niche defines the growth and yield parameters of chickpea. The present study was conducted to investigate the effect of different levels of biofertilizer with and without molybdenum on growth and seed yield of chickpea, at Seed Production Block, SGRR University, Dehradun, Uttarakhand. The experiment included seven treatment groups replicated thrice in Randomized Block Design. It was observed that all growth and seed yield parameters varied significantly with the application of different levels of biofertilizers with or without molybdenum. The observed results showed that all the plant growth parameters like plant height (54.67 cm), number of primary branches (5.34/ plant), number of pods per plants (64.00), fresh weight of plant (81.66 g) were maximum with treatment T6 (20 g Rhizobium+25 g PSB +0.3 g molybdenum/kg seeds). The number of nodules per plant (28.00) and 1000 seed weight (142 g) were recorded maximum with the application of treatment T7 (25 g Rhizobium + 30 g PSB + 0.3 g molybdenum per kg of seeds). The seed yield of chickpea was recorded maximum (15.67 q/ha) with the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds (T6). Thus, our findings indicate that, among all other treatments, the application of 20 g Rhizobium along with 25 g PSB and 0.3 g molybdenum per kg of seeds is suitable for higher seed yield of chickpea in Doon valley of Uttarakhand.
