Organocatalytic acetylation of pea starch was systematically optimized using tartaric acid as catalyst. The effect of the degree of substitution with alkanoyl (DSacyl) and tartaryl groups (DStar) on thermal and moisture resistivity, and film-forming properties was investigated. Pea starch with DSacyl from 0.03 to 2.8 was successfully developed at more efficient reaction rates than acetylated maize starch.

The precision "Systematic and quantitative evaluation of rice drought tolerance and construction of high throughput screening platform" identification and evaluation of rice drought resistance always is the key problem for succession of drought resistance study and breeding. We found that grain yield-related traits of rice have ecological effect with soil moisture conditions. Therefore, gradient and quantitative water controlling (GQWC) experiment was carried out in order to study the evaluation system of rice drought tolerance.

The phenomenon of stay-green and root traits are most important in drought tolerance breeding. The present investigation was conducted to identify the drought resistant staygreen genotypes with desirable root traits which are essential to extract moisture from deeper layers of the soil under drought conditions. Seven stay-green genotypes along with three non-staygreen checks were evaluated for root traits in PVP pipes with different soil moisture regimes under Factorial RBD design with two replications.

Drought is a shortfall of water availability sufficient to cause loss in yield. Agricultural drought is a situation where the moisture supply is inadequate to meet the requirement of the crop. To cope with the drought, resistant/tolerant plants initiate defense strategies against water deficit, which are categorized as morphological and physiochemical/biochemical mechanisms. Plant drought tolerance involves changes at whole-plant, tissue, physiological and molecular levels.

The physical and proximate analysis of the fuel used during cooking was determined. The properties viz., moisture content fixed carbon, volatile matter, ash content was determined and the physical properties like bulk densities, resistance to water penetration and the shatter resistance of agro residue briquettes were determined to know the suitability of fuel for cook stove.

The present investigation was assessed using 235 different F2 individuals, their parents and F1 for characters like plant height, moisture, phenol and chlorophyll. These characters are most important for identification of disease effect and characterization for resistance in plants or genotype. Here, in the present study F2 population was developed from the cross between AT-3 (Solanum lycopersicum L) and IIHR-2101 (Solanum habrochaites L.). Then characters which are mentioned above were studied.

ntroduction of new agricultural technology created growing realization of soil physical properties limiting crop production. However, soil physical changes and their impact on crop production are less easily realized because of their exceedingly complex and dynamic nature. Since the nature and arrangement of aggregates in soils could be expected to have a profound influence on pore space, which in turn would govern air and water relations, wide use has been made of aggregate analyses to evaluate spot physical conditions.

Soil-borne diseases result from a reduction of biodiversity of soil organisms. Restoring beneficial organisms that attack, repel, or otherwise antagonize disease-causing pathogens render a soil disease-suppressive. Plants growing in such suppressive soil resist diseases much better than in soils low in biological diversity.

The present study was conducted to know the nutrition composition of pre-treated foxtail millet rice in comparison with raw foxtail millet grains. Different pre-treatments were given to the millet grains in different combination such as roasting; cooking, drying and roasting. Pre-treatment reduced the moisture, protein, fat content of millet grains significantly (p < 0.05). More reduction was observed in cooked, dried and roasted grains and minimum reduction was observed in roasted grains.

Bacteria grow very rapidly under warmth and moisture. Many plant extracts from roots, stem, leaves, flowers, fruits and seeds of diverse species of plants exhibit anti-bacterial properties. These can be used for treating the textiles and the relatively lower incidence of the adverse reaction of these treatments coupled with reduced cost can be exploited as an effective eco-friendly alternative to the synthetic antimicrobial agents for textile applications.

Cowpea, [Vigna unguiculata (L.) Walp.] also known as blackeye pea, southern pea and lobia is one of the most important food legumes in the semi-arid tropics. With an average of 25% protein (on dry weight basis) in its seeds and tender leaves, cowpea is a major source of protein. In storage, Callosobruchus maculatus F. also called cowpea beetle, cowpea weevil or bruchid, is regarded as the most important and common pest of cowpea both in Africa and Asia. All vigna crops except rice bean are susceptible to bruchids.

The wheat varieties HD-2733 and K-307 were found moderately resistant against Sitophilus oryzae in which higher hardness, lower moisture, lesser eggs, progeny and population with longer developmental period and lesser grain weight loss and damaged grain were recorded. Rest wheat varieties found susceptible to Sitophilus oryzae. Hardness having negative association with pest infestation. While moisture showed positive relation. The fecundity and progeny were positive relation with percent weight loss and damaged grain.

Wheat is an important cereal crop grown worldwide primarily for chapati, bread and biscuits. Target specific wheat breeding and quality improvement programs focus on developing genetically superior, high yielding, disease resistant cultivars with desired quality that are adapted to different growth environments. Drought refers to the condition of reduced soil moisture which induces several changes in crops i.e., morphological, biological, physiological and molecular changes. It also causes reduction in crop yield or in some cases cause crop failure.

A new Baby corn hybrid, GAYMH-1 involving two diversified inbred parents was evaluated across the locations all over India during kharif 2015 to kharif 2017. It yielded on an average 14.36 Q/ha baby Corn yield and found 12.6 % superior in yield over the check HM-4 in the Peninsular Zone (PZ). It yielded on an average 22.99 Q/ha baby Corn yield and it is found 18.6 % superior in yield over the check HM-4 in Central West Zone (CWZ).
