A field experiment was undertaken during kharif 2012 to study effect of biofertilizers and foliar application of organic acids on yield, nutrient uptake and microbial activity of soybean at MARS, Dharwad under rainfed condition. The experiment was laid out in RCBD factorial having twenty treatment combinations and replicated thrice. The treatments comprised of four P-Solubilizers (PSB, VAM, PSB + VAM and Control) and five foliar spray of organic acids (Humic acid, Lecithin, Citric acid, Maleic acid and control). The results revealed that higher seed yield of soybean (35.96 q ha-1) was obtained with the treatment combination of dual inoculation of PSB+VAM with foliar spray of 0.1% humic acid at flower initiation and was higher to an extent 22.5 per cent compared to control (27.90 q ha-1). Similar trend was observed on microbial activity and nutrient uptake (N, P2O5 and K2O) of the soybean crop.

Sweet grain sorghum [Sorghum bicolor (L.) Moench] is a neglected crop mainly grown for its sweet grains in the pasty form. Although its taste is the main character of interest, knowledge of protein related content of the grain, especially when linked to its value for infant porridge appears equally important. The objective of this study was to evaluate the status of crude protein content of pasty grains and to determine genetic correlations between morphological and biochemical traits among sweet grain of sorghum genotypes in Burkina Faso. Eight sweet grain sorghum cultivars (BTO2, BZI1, KBZ4, PBO5, PGO3, SBR7, SPI2, STO4) were evaluated through 13 morphological and two biochemical variables. Crude protein content of these genotypes was also compared with the composition of two controls of sweet stalk sorghum (ETS) and ordinary grain sorghum or common sorghum (EBS). The analysis of variance revealed variability within sweet grain sorghum accessions, mainly on the biochemical traits (crude protein and water content) and two morphological traits (peduncle and panicle lengths), which discriminated significantly in the thresholds of 1 and 5%, respectively. In addition, sweet grain sorghum had low crude protein content compared to other types of sorghum, except, two genotypes of sweet grain sorghum (BZI1 and STO4) which recorded higher protein content compared to the common sorghum. An important and negative correlation was noted between sowing-flowering cycle and protein content.

Investigation on yield improvement and development under drought condition using breeding techniques is difficult, due to the association with low heritability of specific traits. Even more, investigation of physiological indicators (stomatal conductance, chlorophyll index, relative water content, chlorophyll fluorescence, canopy temperature, radiation use efficiency, stay-green etc.) is of interest as they are more accessible, with a low cost, therefore these indicators of physiological traits can be used as good criteria in selecting valuable species. In order to evaluate the effects of water stress on grain yield, its components and some physiological traits of grain sorghum genotypes (Sorghum bicolor L.), a field experiment using split plot design with three replications was carried. The main plots included three water stress treatments: normal irrigation as control, halting irrigation at the stage of terminal leaf emergence and halting irrigation at the stage of 50% flowering. The sub-plots included 10 genotypes of sorghum (‘KGS29’, ‘MGS2’, ‘Sepideh’, ‘KGFS27’, ‘MGS5’, ‘KGFS5’, ‘KGFS17’, ‘KGFS13’ and ‘KGFS30’). Results showed that water stress significantly decreased grain yield and its components (1,000 seed weight, number of seed per panicle) and had various effects on physiological traits. The water stress increased canopy temperature and radiation use efficiency, while stomatal conductance, chlorophyll index (SPAD) and stay-green of genotypes were decreased; the maximum efficiency of photosystem II of photosynthesis remained unchanged between the treatments. Genotypes turned out to have significantly different responses to the drought treatments for all the studied traits, indicating the existence of a high variability among them. In general, physiological traits could be used as good indicators in water stress investigations and might provide comprehensive information as compared with morphological traits.

Summary There is a growing interest in the use of natural products for crop production and protection. Humic acid is a well-known bioresource that intensifies soil functions and improves crop productivity. This review article provides a synopsis of the humic acid-plant-nematode association and the prospects for using humic acid as an alternative to chemical control of nematodes. Humic acid is known to have toxic and antagonistic effects against many plant-parasitic nematodes, including Meloidogyne spp., Rotylenchulus reniformis, Radopholus similis and Helicotylenchus multicinctus. The required dose for getting significant nematode control ranges from 0.04 to 2.0% concentration. Delivery methods like soil application or drenching, seedling root dip treatment and foliar spray on leaves are effective for nematode control. Humic acid controls plant-parasitic nematodes through various mechanisms including killing juveniles, inhibiting hatching, reducing nematode infectivity and reproduction, and inducing systemic resistance. Humic acid is compatible with bio-inoculants such as Azospirillum spp., phosphobacterium, Bacillus megaterium, Pseudomonas fluorescens, Trichoderma viride, Glomus spp., Pochonia chlamydosporia, Purpureocillium lilacinum and T. asperellum. These attributes of humic acid show a promising potential for use in nematode control. However, further work on bio-efficacy against a broad spectrum of plant-parasitic nematodes is needed.
