Background: Glomus intraradices fungi and three bio-inoculants (Pseudomonas fluorescens, Trichoderma viride, and Trichoderma harzianum) are known to have certain beneficial effects on germination and seedling growth of several tropical fruit crops. A pot study was conducted to evaluate the effects of arbuscular mycorrhizal (AM) fungi and bio inoculants on seed germination and seedling growth of a papaya cultivar Gujarat Junagadh Papaya-1 at regional horticultural research station (RHRS), ASPEE College of Horticulture and Forestry (ACHF), Navsari Agricultural University, Navsari, Gujarat, India.

Methods: The seeds of papaya were sown in the Monsoon season (June-Aug 2019) in polybags. The seeds of papaya were coated by AM fungi (G. intraradices), three bio inoculants, and their combinations. There were 9 treatments including control treatment.

Results: An application of T. harzianum was found to be the most effective on seed germination and seedling growth by enhancing germination percentage (89%) along with early emergence (6 days) and consolidating all the growth parameters. T. harzanium was also effective on underground plant parts such as tap root length and diameter. The combination of all four bio-inoculants also gave significant results. Results from this study could be helpful for the West Indian fruit growers by enhancing the opportunities to use bioagents for sustaining their farming systems.

Two field experiments were conducted at the village of Khaled Ibn El-waleed, Sahl El-Hossinia Agricultural Research Station, El-Sharkia Governorate, Egypt, during the two summer seasons 2019 and 2020 to estimate the effect of NPK nano-fertilizers, bio-fertilizers and humic acid (in addition to different doses of mineral fertilizers) on soil chemical properties and productivity of soybean in saline soil. The treatments were NPK-chitosan, NPK-Ca, humic acid, biofertilzer and control (mineral NPK only). In the two seasons, the experiment design was a split plot in three replicates.

The results indicated a slight decrease in soil pH, while there was a significant decrease in EC values in all the studied treatments as compared to control. Also, the soil available macronutrients (nitrogen, phosphorous and potassium) and micronutrients (iron, manganese and zinc) were significantly increased after application of the studied treatments as compared to control. Also, there was a significant increase in the content of macro and micronutrients in soybean grains as affected by the studied treatments. This may be attributed to that addition of the used amendments like nano chitosan, humic acid and biofertilizers companied by decomposition of organic materials released acids that reduced soil pH which caused nutrients to be more soluble hence more available for plant uptake. The results indicated also a significant increase in the soybean yield parameters as plant height, weight of seeds and weight of pods in all treatments as compared to control. There was also a significant increase in the soybean content of protein, oil and chlorophyll in all of the investigated treatments as compared to control.

Rice is a reliable dietary source in most of the underdeveloped nations, where the majority of people are deficient in minerals and vitamins. Hence, it is necessary to focus on the development of nutrient rich rice for value addition in order to alleviate malnutrition. Dietary fibre, minerals, carotenoids, flavonoids and polyphenols are abundant in traditional rice cultivars and consumption of these traditional rice cultivars, on the other hand, benefits human health. Now-a-days, traditional rice varieties are gaining importance and it is cultivated by a large number of farmers. These varieties play a major role in the history of crop improvement and seed production. Hence, an experiment has been conducted to analyse the bio chemical properties viz.,a-amylase activity, dehydrogenase activity and total phenol content in sixteen traditional rice varieties viz., Mappillai samba, Kichadi samba, Vellaikavuni, Rajamannar, Sembuli samba, Kattuyanam, Karunkuruvai, Norungan, Poongar, Kuzhiyadichan, Chithiraikar, Paalthondi, Maranel, Salem sanna, Kallurundai kar and Illuppai poo samba which were collected from the gene pool of Department of Plant Genetic Resource, Tamil Nadu Agricultural University, Coimbatore. Among the varieties tested, the maximum a-amylase activity and dehydrogenase activity were recorded by Sembuli samba (4.88 mg maltose min-1), Poongar (3.40 mg maltose min-1), Maranel (3.40 mg maltose min-1) and Maranel (0.609), Salem sanna (0.596), Vellaikavuni (0.562), Karunkuruvai (0.522), respectively. The total phenol content was maximum in Sembuli samba (45.36 mg/100g), Kattuyanam (42.34 mg/100g), Mappillai samba (38.84 mg/100g) and Kallurundai kar (38.24 mg/100g). Among the sixteen traditional varieties, Sembuli samba, Kattuyanam, Mappillai samba and Kallurundai kar have the high secondary metabolites with improved seed quality. The results of this experiment revealed that the above traditional rice varieties have to be conserved its precious genome information due to their superior performance of a-amylase activity and dehydrogenase activity as well as maximum phenol content.

Aims: This research aims at evaluating the effect of salt stress on plant growth, Na+, K+, proline and soluble sugars contents in leaves and roots of local cultivar of African basil in Republic of Benin.

Study Design: The experiment was laid out in a Completely Randomized Design (CRD) having five treatments and three replications.

Place and duration of Study: The experiment was carried out in screening house under natural conditions at the Center of Agricultural Research of Agonkanmey, Commune of Abomey-Calavi, Republic of Benin from January to February, 2020.

Methodology: Five salt concentrations (0, 30, 60, 90 and 120 mM) were used to irrigate three weeks old plants for two weeks. After two weeks, plant growth, sodium (Na) and potassium (K), proline, and soluble sugars contents of leaves and roots were determined.

Results: Salt stress induced a significant reduction (p = .05) in shoot growth from 60 mM NaCl but had no impact on the number of leaves and shoot water content. Root growth was significantly reduced (p = .05) already at 30 mM NaCl. Leaf and roots Na+, proline and soluble sugars contents significantly increased (p = .05) under salt stress whereas K+ content decreased significantly (p = .05) only in root.

Conclusion: Salt stress reduces the growth of African basil plants due mainly to Na+ ion toxicity. The ionic selectivity ratio (K+/Na+) rather than the K+ ion content plays an important role in the response of basil plants to salt stress, while both proline and soluble sugars accumulation may contribute to osmotic adjustment.

A field experiment was conducted at the Crops Research Institute (CRI) at Fumesua – Kumasi from August to December, 2017. The research was to investigate the growth and yield characteristics of sweet potato (Ipomoea batatas L) to the application of organic manure (poultry manure and cow dung) and inorganic fertilizer (NPK, 15-15-15, 300kg/ha) and their combinations. The experiment was a 2x3 factorial with treatments arranged in randomized complete block design (RCBD) with three replicates. The treatments were: sole poultry manure (6t/ha); sole cow dung (8t/ha); sole NPK45-45-45kg/ha; NPK, 22.5-22.5-22.5kg/ha + Poultry manure (PM) (3t/ha); NPK, 22.5-22.5-22.5kg/ha + Cow dung(CD) (4t/ha); NPK, 33.75-33.75-33.75kg/ha + PM (1.5t/ha); NPK, 33.75-33.75-33.75kg/ha + CD (2t/ha); NPK, 7.5-7.5-7.5kg/ha +PM (4.5t/ha); NPK, 7.5-7.5-7.5kg/ha + CD (6t/ha); and no fertilizer amendment (control). Two sweet potato varieties, ‘Apomuden’ and ‘Santom Pona’ were used. The results indicated that on the average, the organic manure and the inorganic fertilizer combinations promoted greater growth than the sole applications and the control.  The greatest marketable root yield (14.8 t/ha) obtained from 7.5-7.5-7.5 NPK + 4.5 t/ha PM. For root dry matter, NPK 22.5-22.5-22.5 + CD (4t/ha); NPK 22.5-22.5-22.5 + PM (3t/ha); and NPK 7.5-7.5-7.5 + CD (6t/ha) produced the greatest responses (32.6%, 31.1%, and 30.9%) respectively. Integrated application of organic manure and inorganic fertilizers is thus recommended for improved sweet potato production.

International Journal of Plant & Soil Science, Page 105-113
DOI: 10.9734/ijpss/2022/v34i1731042

In the current study a total of 191 maize inbred lines were set up in an augmented randomized complete block design to study the genetic variation and interrelationship of different yield contributing parameters. Observations were recorded on a total of nine phenological and ear / kernel related traits. Significant results for ANOVA indicated presence of substantial variation while the first three axes of PCA could explain 75.54% of the variation present. Ear and flowering traits were orthogonal to each other and the highest variation in PC1 could be attributed to total grain weight. This was also reflected in the Agglomerative Hierarchical Clustering which grouped the inbreds into five clusters primarily on the basis of total grain weight which accounted for the highest variation between the clusters. Substantial heritability genetic advance as percentage of mean were observed for total grain weight indicating that selection for grain weight would be fruitful. Association and path coefficient studies after adjustments for multi-collinearity using k constant method (0.05) revealed that total grain weight was highly and positively correlated with ear weight, number of grain kernel rows and seed index. Therefore, simultaneous selection for these traits would be useful. Overall, our studies go on to show presence of sufficient genetic variability in the inbreds under study and hybridization between inbred lines grouped in different clusters have a high chance of producing heterotic hybrids.
