MANAGING CROP PRODUCTION OF POME GRANATE CV.WONDERFUL VIA FOLIAR APPLICATION OF ASCORBIC ACID, PROLINE AND GLYCINBETAINE UNDER ENVIROMENTAL STRESSES
ABSTRACT:

Recent studies that subjected number of abiotic stresses simultaneously figured out different effect of their combination on plant performance and production compared to each single stress. The effect of such combinations are naturally exists and already translated to weak act and output of plants. The plants in this investigation field suffered soil salinity which affect soil osmotic pressure subsequently decreases soil water potential and this lead to a physiological drought stress. Additionally, Egypt’s solar recorded 2,000 to 3,000 kWh/m2/year of direct solar radiation which cause increase temperature on leaf surface and soil. The present trail aimed to simulate plant acclimation to environmental stresses by exogenous metabolites like generated by plants under stresses such ascorbic acid (Asc), proline (Pr) and glycinbetaine (GB). Eight treatments including control, 10 mM Asc, 50 mM Pr, 100 mM GB and the combination between them were applied on wonderful pomegranate trees aged four years at end of March, full fruit set and one month later. In ascending order all applications significantly stimulated all parameters under investigation compared to check treatment. The study recommend the combined application of 10 mM Asc plus 50 mM Pr plus 100 mM GB for alleviation negative effects of environmental stresses which may happen to performance and yield of pomegranate trees.

ADOPTION OF CLIMATE SMART AGRICULTURAL PRACTICES AND FARMERS’ WILLINGNESS TO ACCEPT INCENTIVES IN NIGERIA
ABSTRACT:

Climate Smart Agricultural (CSA) practices has been identified as a key element in the successful response to the threats of climate change to sustainable agricultural production and food security in Africa. This study determines the extent of adoption of selected CSA practices and farmers’ willingness to accept incentives for adoption of CSA practices in Nigeria. A multistage sampling procedure was used to select sample of farmers from four states in the North Western geopolitical zone of Nigeria. Data were collected through interview schedule using questionnaire. Descriptive statistics was used to analyze the data. The results showed that adoption of the selected agricultural practices was generally low (<50%). A larger proportion (ranging from 72% to 80%) of respondents indicated their willingness to accept appropriate incentives to shift to the selected CSA practices. The mean financial incentives an average farmer is willing to receive to shift from his/her production system to the specified CSA option, are: N36, 522.00, N85, 715.00, N56, 255.00 per hectare per season for adoption of Agro forestry, CSA with manure and CSA without manure respectively. Sensitization of farmers on the need to adopt climate smart practices towards reduction of adverse effect of climate change should continue. Financial incentives should be introduced to improve farmers’ adoption of CSA practice.

SUSTAINABLE AGRICULTURE AND ENVIRONMENT: HOW THE MODERN POLICY IS PROMOTED IN AZERBAIJAN CONTEXT
ABSTRACT:

Modernization of agriculture is announced as a strategic goal since 2015 in Azerbaijan with the aim of to replace import of important foods (wheat and increase the agriculture export. A trend in rapid population growth and increasing demand for food, changing environment evidently proofs to realize measures for sustainable, economically efficient and environmentally friendly agriculture sector. Current agriculture practices in the country are faced with the land fragmentation, poor irrigation systems, significant water losses, insufficient knowledge of farmers and other observed shortages in agriculture leading to reduction of the overall productivity of irrigated lands and worsening of their farming characteristics. Based on the quantitative analyses on the data the features of agriculture are investigated by assessment of the main influencing factors to sustainability of the current farming system. Examples from international experiences and region countries are reviewed to demonstrate similarity and dependence of the sustainability measures on the local conditions and agriculture practices. The result of this study proves that modern agriculture in the country is possible to be achieved through supporting the integrated and interlinked set of the measures, including consolidation of the small plots, construction of the new generation irrigation systems, strengthening and mobilization of the scientific and institutional capacities enabling realization of the new agricultural policy, education of the stakeholders with the advanced knowledge on the modern agriculture practices and its transfer to the farmers. The outcomes of this study provide well-grounded proposals in the preparation of action plans for the smooth implementation of the declared agricultural development strategies in the country and practical experience for other similar emerging market economies.

LEVERAGING ROLE OF BIOSTIMULANTS ON GROWTH, YIELD AND QUALITY OF TOMATO (Solanum Lycopersicon)
ABSTRACT:

Nowadays the contests confronted by the agriculture sector are huge. Therefore growing agricultural practices entail more fertilizers for higher crop yield.  Presently, to nourish increasing population, extensive requirement for environmental friendly agriculture for the production of healthy and good quality food is in high demand. For a sustainable way of crop production with different organic and botanical fertilizers from natural resources to boost commercially important crop production efforts are under ways. The field experiment was laid out in summer 2017, aimed at evaluating the influence of diverse formulation of natural substances/ biostimulants on crop yield, quality characteristics of fruit and contents of macronutrients in determinate type of tomato (Solanum lycopersicon). Five biostimulant i.e. GB, SM, WK, BM, BS were applied by foliar way along with recommended dose of synthetic fertilizer after transplanting and their performance was recorded during vegetative and reproductive stages. Foliar application of these biostimulants had significant (p<0.05) effects on tested parameters of tomato crop over the control. Application of these biostimulant increased plant height (9.0%), No. of branches plant-1 (55.5%), fruit yield (17.0%) and quality parameters i.e. total carbohydrates (38.0%), soluble proteins (20.0%), Vitamin C (12.0%), TSS contents (39.0%)over control. Therefore it could be concluded   that agricultural biostimulants may be a dynamic approach to boost the yield of tomato and other vegetable crops.

FORMULATION OF AN ORGANIC POTTING MEDIUM ENRICHED WITH Trichoderma SPP. AND THEIR EFFECT ON GROWTH AND DISEASE SUPPRESSION OF Solanum melongena L
ABSTRACT:

Trichoderma spp. are fast growing fungi, widely used as bio-control agents for controlling soil-borne diseases of plants as well as growth promoters. The current study was conducted to investigate the effect of three Trichoderma spp. (T. virens, T. harzianum and T.asperullum) inoculated compost media on growth and disease suppression of Solanum melongena. Selected three Trichoderma spp. were mass produced separately, in 250 g of sawdust as carrier material. They were incorporated in to prepared compost media (1:1:2:2:2 ratio of cow dung, poultry rice husk, Panicum maximum, Tithonia diversifolia and Mikania scandans) at the higher frequency. Effect of Trichoderma spp. amended compost media were evaluated using S. melongena by measuring several growth parameters and disease incidence 60 days after planting in the field of Centre of Excellence for Organic Agriculture, Makandura, Gonawila. The highest mean plant height (75.8±2.25 cm), number of flowers per plant (18±2) and yield (18.5±3.25 ton/ha) was observed the application of compost with Trichoderma amended (T-4) treatment. S.melongena planted without Trichoderma treated in field soil (T-1) showed a significantly lower growth parameters than the others treatments. Trichoderma with compost treated S. melongena showed significantly and decreased disease incidence (12 %) as compared with untreated controls. It can be concluded mixing of compost media with Trichoderma amendment could influence plant growth and the reduction of soil-borne diseases in S. melongena.

SENSITIVITY OF OILSEED RAPE (Brassica napus L.) TO SOIL RESIDUES OF IMAZETHAPYR HERBICIDE
ABSTRACT:

Imazethapyr is one of imidazolinone herbicides that may leave residual activity in the soil for extended periods causing injury and yield reduction of susceptible crops in rotation. An experiment was conducted in order to study the sensitivity of oilseed rape (Brassica napus L.) to imazethapyr soil residues. Experimental type was completely randomized design with three replications. Treatments included Imazethapyr simulated concentrations residuals in soil (0.002, 0.004, 0.008, 0.012, 0.02 and 0.04 mg. kg-1soil). Shoot and root biomass production was measured 30 days after emergence. Oilseed rape responses to imazethapyr residues was fitted with sigmoidal 3 and 4 parametric equations to the root and shoot biomass data as a function of the herbicide residue concentrations and was used to calculate the doses for 50% inhibition of root and shoot growth (ED50). Results showed that the oilseed rape shoot and root dry matter were significantly affected by increasing imazethapyr soil residue (p<0.01). This reduction in root dry matter was severe than shoot dry matter, where root ED50 (0.0019 mg.kg-1soil) was less than shoot dry matter (0.0025 mg.kg-1soil). Considering the high sensitivity of oilseed rape to imazatepara residues, attention is needed to provide oilseed rape cultivation in fields with a history of imazateaper application.
