Effect of different levels of nitrogen and phosphorus on cowpea [Vigna unguiculata (L.) Walp] under rainfed conditions of Rajasthan
Get PDFAn field experiment was conducted during kharif 2014 and 2015, at Central Sheep and Wool Research Institute, Avikanagar (Rajasthan) to study the effect of nitrogen and phosphorus levels on growth attributes, herbage yield and quality of fodder cowpea [Vigna unguiculata (L.) Walp.]. All growth attributes were significantly (plant height, branches/plant) higher with 30 kg N/ha applied to cowpea. Maximum green fodder, dry matter yield and crude protein content were recorded (178.11 and 36.12 q/ha and 18.07%) with the use of 30 kg N/ha. Besides, Crude protein content was increased greater extent upto 30 kg N/ ha, but the differences between 20 and 30 kg N levelswas found remained at par with each other for protein content in haulm of cowpea. The application of phosphorus upto 60 kg P2O5/ha resulted maximum raised in green fodder and dry matter yield (179.06 and 35.83 q/ha) as compared to other levels. Crude protein content in dry matter was responded well upto 60 kg P2O5 /ha and it was increased by (12.50%) higher over control. The higher net return in terms of gross income (Rs. 28896/ha), net return (Rs. 17044/ha) and benefit: cost ratios (1.69) were realized under 30 kgN/ha. Similarly, 60 kg P2O5 /ha in cowpea gave the additional gross return (Rs. 8100/ha) and net return (Rs. 1769/ha) as compare to without use of phosphorus. Significant interaction of nitrogen and phosphorus levels was noted on green fodder yield
Biotic stress inducible promoters in crop plants- a review
Get PDFPromoter is a DNA sequence that regulates the expression of a particular gene. They are classified on the basis of their function and spatio-temporal expression into constitutive, tissue-specific or development-stage-specific and inducible promoters. Plant genes associated with defence responses are activated by stress-factors and these genes are known to be regulated by promoters or the upstream elements. Promoters induced by abiotic stress factors in plants are fairly well studied compared to biotic stresses. This review presented information generated on promoters and regulatory elements involved in defence gene expression due to insect damage, pathogen and nematode attack to crop plants, mechanism and their utilization in crop improvement through genetic engineering
Traditional phytotherapy used by the rural peoples of Hamirpur District of HP in the treatment of sexually transmitted diseases mainly Gonorrhea and Syphilis
Get PDFIndigenous knowledge about particular floral diversity of an area is necessary for the identification of plants and their traditional uses for the purpose such as for food, fibres, fertilizer, fodder, fuel ritual and medicinal importance. In present paper the emphasis will be given on medicinally importance plants for primary health care. The present paper reveals that there are sixteen plants species which belongs to thirteen families are used for therapeutical or traditional uses as indigenous plants of Hamirpur district for the primary health care or treatment of sexually transmitted diseases
