Abstract

Fodder trees in agro-forestry system are planted to overcome the effects of the seasonal shortages or to insure against risks of drought and also to deliver benefits such as shelter, soil conservation, timber and fuel wood. An attempt was made to investigate the performance of fodder trees in the presence and absence of crops. The data pertaining to growth parameters and biomass parameters of the four fodder trees from an agro-forestry experiment for six years (1999-2005) was analyzed. Contrast analysis has been performed to study the performance of the different tree species with and without crops. The combined analysis of the tree data over the years was also performed.

Abstract

Mango is a perishable fruit and its ripening period coincides with the summer months under north Indian conditions. It has very short life at ambient temperature and high post-harvest losses. Keeping it in view, an experiment was planned to study the effect of putrescine and LDPE packaging on storage life and quality of mango fruits cv. Langra. Physiologically mature and uniform fruits of mango were treated with putrescine @0.0, 1.0, 2.0 and 3.0 mmolL-1. Treated fruits were air dried in shade and packed individually in perforated LDPE bags before storage at 130 C and 85-90 per cent RH for 4 weeks. Results revealed that fruits treated with putrescine @2.0 mmolL-1 alongwith LDPE packaging retained best quality in terms of high palatability rating, good blend of TSS and acidity and low physiological loss in weight and spoilage percentage

Abstract

SSRs or microsatellites are tandem repeats of 2-8nt units of DNA and are ubiquitous in all genomes studied so far. SSR markers have many advantages over the other marker systems. The first advantage is their high reproducibility, which would be the most important in genetic analysis. The second advantage of the SSR marker system is the polymorphic genetic information contents. The third advantage has to do with the co-dominant nature of SSR polymorphisms. The fourth advantage of the SSR marker system is their abundance and distribution in genomes. A fifth advantage of the SSR marker system is that SSRs are preferentially associated with non-repetitive DNA. This review focuses on some of the reasons for SSR mutations that occur due to replication or repair process which may depend on not only the motif size but also the nucleotide composition of each motif as well as orientation of repeats or position with reference to replication origin. In this review tools for SSRs available are given with their advantages and disadvantages.

Abstract

Mungbean (Vigna radiata L.) (family Fabaceae) is a diploid (2n = 2x = 22) pulse crop, cultivated predominantly in South East Asia. The genus Vigna also contains several major agriculturally important legumes like black gram (V. mungo), rice bean (V. umbellata), moth bean (V. aconitifolia) and adzuki bean (V. angularis). The grains are rich in protein and minerals and hence form important component of human diet. Mung bean is reported to be domesticated in India approx. 4,000-6,000 years ago.

Abstract

The brinjal crop covers largest area and plays an important role in total vegetable production in India. Brinjal crop suffers more from fruit and shoot borer insect pest and disease attack. Due to lack of awareness of farmers, KVK scientists promoted the integrated pest management practices in district for the suppression of pests and diseases. The integrated pest management strategy involving many components was demonstrated through innovative large scale contagious technology demonstration in 20 ha brinjal (local variety) crop area during the year 2014 during Kharif season in Mau district in Uttar Pradesh, India. The various production and protection parameters indicated that adoption of IPDM strategies decreased the cost of production without affecting the yield. The IPDM demonstration, insecticides sprays quantity reduction in brinjal was 100 lit. per hectare, respectively as compared to the local check. Adoption of IPDM technology increased the net income over the local check in brinjal local varieties Rs. 2,57,500/ha. In spite of increase in yield of brinjal, technological gap, extension gap and technology index existed. The improved technology gave higher gross return, net return with higher benefit cost ratio as farmers’ practices.

Abstract

Vulnerability of agriculture to climate change is becoming increasingly apparent in recent years. During 2014 and 2015, India experienced trails of unusually widespread and untimely hailstorm events. The increased frequency of hailstorm events, especially in vulnerable ecosystem of Deccan Plateau region of India demanded appropriate measures to minimize adverse impact on agricultural crops. Therefore some of the post-hail measures including nutritional supplement, plant bio-regulators and canopy management were evaluated in field trials conducted at Maharashtra, India during 2014 and 2015. Amongst these, pruning of the hardy and indeterminate eggplant crop induced effective branches, which produced more flowers and fruits. Nitrogen supplemented with urea drenching and stress alleviating effects of salicylic acid promoted recovery in maize while drenching with humic acid along with spraying of potassium nitrate improved productivity of onion. These studies indicate the potential of technological interventions to cope with extreme events such as hailstorms.

Abstract

Prioritizing and targeting less developed regions is one of the multi-pronged strategies for doubling farmers’ income (DFI) in India. Using an indicator approach, the present study assessed and mapped agro-ecological sub-regions (AESRs) based on ten indicators representing production, infrastructure, information, marketing and income of the farmers. On the basis of the composite index of agriculture development, AESR 9.1 and AESR 1.1 were found to be the most and the least developed regions respectively. Further, the potential districts for each of the less-developed AESRs have been identified for greater prudency in planning. The study concludes that for achieving the target of DFI within the stipulated time-frame, it is imperative to mainstream AESR-based planning in technological development and dissemination. The evidences revealed large and equitable response of the efforts targeted towards less-developed regions.

Abstract

In the present study, seismic and well log information is incorporated with a multi-layer feed-forward neural network (MLFN) to predict porosity in the inter-well region. The aim of this study is to estimate a relationship between porosity and impedance to characterize the reservoir, if any, in the offshore F3 block, the Netherlands. MLFN is used to generate a connection between porosity logs and a set of seismic attributes, which are further used for porosity prediction. Modelbased inversion is employed to produce an acoustic impedance volume, which is a reliable technique for quantitative estimation of reservoir characteristics and acoustic impedance. The model-based inversion results indicate that the acoustic impedance (AI) in the region varies from 2500 to 6200 m/s*g/cm3, which is comparatively low and indicates loose formation. Thereafter, AI along with other attributes estimated from seismic data, is used as an input in MLFN, and porosity is predicted. The technique is first implemented on the traces close to well locations, and the findings are correlated with well log information, and after appropriate matching, the entire seismic segment is inverted for porosity. The results indicate that the porosity varies from 0.07 to 0.40. Further, a relationship between predicted porosity and inverted impedance is derived to represent the connection between these two parameters in the region. Moreover, based on this study, it is concluded that there is no significant reservoir in the region. However, as the analyses are performed for a specific range of data, it is possible that other parts of the area may have a different stratigraphy and possibility of the primary reservoir in the area.

Abstract

This study deals with the factors hindering the adoption of innovations in the arid agro-ecosystems of India. Adoption of agricultural technologies helps increase agricultural output, which can impact poverty levels and environmental degradation. The present study was conducted in Rajasthan, India, to identify the technology adoption of agricultural households and various socio-economic and socio-personal factors affecting the same. Among several coping strategies for climate vulnerability, other than a shift towards rainfed crops, reducing the number of irrigations, deepening existing wells and advancing or delaying irrigation were common in the arid ecosystems. Some important policy measures have been drawn from this study. First, the sustainable development of groundwater resources, particularly in the low-productive eastern region, would go a long way in improving agricultural productivity in the country. Agricultural productivity can also be improved by increasing fertilizer use. Second, it proves cost-reducing technologies and creates awareness of better resource-saving options for better returns. Finally, advisory services and the availability of extension personnel are important in rural development.
