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.

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)

The present study was carried out at Central Potato Research Station, Shillong during 2013 and 2014 to assess the growth and yield performance of three grades of in-vitro produced micro-tubers viz. >8 mm, 4-8 mm and <4 mm of two potato (Solanum tuberosum) cultivars namely Kufri Girdhari and Kufri Megha under field planting conditions. The experiment was laid out in a randomised block design with four replications using a common spacing of 50 × 20 cm. The larger grade micro-tubers generally exhibited better physiological growth as well as yield parameters. The larger sized micro-tuber (>8 mm) showed significantly superior plant survival, canopy cover, plant height, number of compound leaves per plant, number of stems per plant and plant vigour followed by 4-8 mm grade and <4 mm grade micro-tubers. Similar trend was observed for all the yield parameters. Among varieties, Kufri Girdhari out performed Kufri Megha in all the growth and yield parameters in all the micro-tuber grades. Thus both micro-tuber size and genotype influenced the field performance. The overall finding indicates that micro-tubers irrespective of the size for both the varieties can produce mini-tubers successfully under direct field conditions in the NEH region which will facilitate quality seed production.

The experiment was aimed at assessing the effect of zinc solubilizing isolates on the available zinc content, growth and yield attributes of paddy. The study was conducted using a randomized block design at the experimental plots of Agricultural Research Station, Dhadesugur. The isolates namely MZSB 6 and MZSB 8 were tested for in vitro solubilization of the zinc and later brought under field condition. 25-day-old paddy seedlings were dipped in lignite based biofertilizer slurry and transplanted according to treatments. Data on growth and yield parameters of paddy were taken at regular intervals of 30 DAT, 60 DAT and 90 DAT and available plant zinc content were estimated using the Inductively Coupled Plasma Mass Spectrometry. Growth and yield parameters of paddy showed a significant increase in the treatment that received combination of MZSB 6, MZSB 8 and 75% recommended dose of fertilizer (RDF) as compared to control and other treatments. Results also showed the highest available zinc of 46.18 mg kg-1 of plant estimated using the ICP-MS. Thus, the results revealed that the combination of both isolates with 75% RDF was found to be efficient in enhancing growth and yield of paddy.

A field experiment was conducted during the dry seasons of 2012 and 2013 in Irrigation Research Station, Talata Mafara, Zamfara State, Latitude 12°34ʹ00ʺ N and Longitude 6°04ʹ00ʺ E 488m above sea level in the Sudan savanna agro-ecological zone. The objective of the research was to test the effect of rice varieties to various levels of nitrogen (N) fertilization under irrigation. The experiment was laid out in a Complete Randomize Block Design (CRBD) using split plot arrangement and was replicated three times. Three rice varieties (Faro 44, 45 and 57) were allocated to the main plot and three nitrogen levels (60, 120 and 180 kg N ha-1) were allocated to the sub plot. The gross and net plot sizes were 5 x 4 and 3 x 3 m respectively. Weeds were controlled using Glyphosate as pre-plant, Butachlor as pre-emergence and Orizo plus as post-emergence herbicides and supplemented with hand pulling at 9 WAS. Fertilizer was applied in two split doses. First half was applied at planting using NPK and the remaining half at 6 WAT using Urea (46 % N). Data collected were analyzed using analysis of variance (ANOVA) and significant means were separated using DMRT at 5 % level of probability. The result of the effect of variety on growth parameters showed that Faro 44 recorded higher days to 50 % anthesis but was significantly (p≤0.05) shorter in height than Faro 57. The effect of the treatment on yield parameters showed that Faro 44 recorded higher thrashing percentage, 1000-grain weight and number of grain panicle-1 significantly (p≤0.05) higher than Faro 45 and 57 in all the seasons. Increasing nitrogen levels from 60 kg N ha-1 significantly increased growth and yield parameters. Application of 180 kg N ha-1 on Faro 44 is hereby recommended for rice growing in the ecological zone.

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2019-2020 and 2020-2021 to investigate the effect of vermiwash on growth, yield and quality of brinjal and to find out suitable foliar dose of vermiwash for optimizing the yield of brinjal. There were five treatments comprising T1= Chemical fertilizer (CF) + foliar spray of distilled water (control), T2 = CF + foliar spray of 10% vermiwash, T3 = CF + foliar spray of 20% vermiwash, T4 = CF + foliar spray of 30% vermiwash and T5= CF + foliar spray of 40% vermiwash. Results revealed that, vermiwash treated brinjal plants showed better growth and yield parameters than the control plants. The highest average brinjal fruit yield (29.99 t ha-1) was found in T3 treatment i.e., foliar spray of 20% concentration of vermiwash and the lowest (26.35 t ha-1) came from control. On the other hand, nutritional quality (moisture content, TSS, β carotene and nutrient content) were seen to be higher in vermiwash treated treatment compared to control treatment. The study suggests that, 20% concentration of vermiwash could be used as effective foliar spray for eco-friendly and higher yield of brinjal.

Background: French bean (Phaseolus vulgaris L.) is an important and widely grown leguminous vegetable. The area under this crop in protected cultivation is increasing due to its high yield and remunerative price. There is scanty of information on pacing and nutrients for fertigation under protected cultivation. Hence the experiment was carried out to determine the effect of spacing and fertigation on growth and yield parameters in French bean under naturally ventilated polyhouse during Kharif 2018 at Zonal Agricultural and Horticultural Research Station, Navile, Shivamogga.Methods: The experiment was laid out in split plot design with three replications. There were 18 treatment combinations comprised of three different spacing treatments and six fertigation treatments. Result: Among all the treatments significantly highest number of primary branches (8.70) and secondary branches (8.50) at 45 days after sowing (DAS), number of pods plant-1 (220.20), pod length (20.66 cm), pod girth (2.95 cm) and pod weight (17.69g) were recorded in the treatment combination with 60 × 75cm with 44:70:53 kg ha-1 + mulching + micronutrient spray. The least number of primary branches (4.27), secondary branches (4.50), number of pods plant-1 (160.33), pod length (15.61cm), pod girth (1.75 cm) and pod weight (13.88g) were observed in the treatment combination with 60 × 45 cm spacing with 33:52.5:39.75 kg of N:P:K kg ha-1. The higher plant height at 45 DAS (480.50 cm) and yield (13.06 t) for 1000 m-2 was found in treatment combination 60 × 45cm with 44:70:53 kg ha-1 + mulching + micronutrient spray (S3T4). It was concluded from the study that, the closer spacing (60 × 45cm) with the combination of 44:70:53 kg ha-1 (N:P:K), mulching and micronutrient spray resulted in higher pod yield (13.06 t) 1000m-2.

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 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.
