Abstract

The application of Trichoderma viride on loose smut infected seeds (Ustilago segetum var. tritici) or in soil, reduced the smutted tillers up to 17.5 per cent. However, treatment of T. viride alone was not as effective as carboxin seed treatment in the control of loose smut. Maximum reduction was observed in dry seed treatment with antagonist as well as seed treatment plus soil application. The effect of T. viride was more prominent in the seed lot having lower level of loose smut infection. Application of T. viride along with half dose of carboxin was however. found as effective as full recommended dose of carboxin (2.5 g/kg of seed). Soaking of seeds in tap water for 24h also reduced tbe incidence of loose smut by 15.4 per cent.

Abstract

Phylloplanc mycoflora isolated from four wheat varieties viz., Arjun, WL 711, Sunalika and HD 2285 showed no variation among themselves. Out of 19 fungi isolated, three pruvcd to he antagonistic to Neovossia indica (Mitra) Mundkur. In dual culture, Aspergillus Iliger v. TieghenL,Gliocladium virens Miller et al and Tricllmierma viride Pers. ex Fr. hyperparasitized and lysed the colonies of N. indica. Cell-free culture filtrate of these fungi reduced the germination of tcliospors as well as sporidia.

Abstract

Punjab is a prosperous state in India with the highest per capita income' and lifestyles similar to that of industrialized western population. About 70 per cent of Punjab's population reside in villages. Due to the adoption of new technologies, daily activity pattern of rural families has changed from heavy to moderate. This is particularly true of the central plain zone of the state. The agricultural development and adoption of mechanization is affecting their food and nutrient intake. People are ignorant about their dietary requirements and prefer to consume energy dense foods. Improper dietary practices increase the risk of diet related chronic diseases such as cardiovascular diseases, diabetes and hypertension. Diet surveys are carried out to determine the nutrient adequacy of various population groups. Most of the studies available supply information on total food intake while data on individual food and nutrient intake are scanty.

Abstract

Recharging groundwater through rooftop-harvested rainwater has immense potential. In order to manage the instant increase in storm run-off generated from high-intensity rainfall events, a filtration system with high-flow rate is required. Filtration through sand beds is a technique accepted world-wide, but its filtration rate reduces drastically with increase in inflow sediment load. For maintaining the pace in filtration rate through sand bed, a highly efficient, low-cost pre-filtration unit fabricated using cotton mat is recommended. The performances of three- and four-layer cotton mat filters have been evaluated using inflow sediment concentration of 50 and 100 mg/l. Results show that the four-layer cotton mat filter starts delivering sediment-free water much earlier than the three-layer filter, especially at the lower inflow sediment concentration. Moreover, the sediment trapping pattern is influenced by inflow sediment load and the first layer of the cotton mat. Experimental results show that the performance of the cotton mat filter is excellent and can be used as a cost-effective and reliable pre-filtration unit for handling the instant increase in storm runoff during groundwater recharging.
