The study was conducted to evaluate the effect of concentrated sulphuric acid treatment on germination of Rubus ellipticus seed and it was observed that fresh seed treated with acid for 20-30 minutes exhibited maximum germination whereas stored seed (3 months) required acid treatment for 45-60 minutes duration for maximum germination.

In North-Western Himalayas spruce and silver fir are normally planted in pits of 30 cm3 size. This method of planting is both expensive and time consuming. Spade planting of spruce and silver fir was tried, which was assessed six times faster and also five times cheaper than pit planting. It also gave better survival than pit planting, therefore, spade planting of spruce and silver fir is recommended.- Effect of Seed Weight on Germination and Initial Seedling Growth in Spruce (Picea smithiana Wall, Boiss)

An experiment was undertaken to study the effect of seedlings size on the growth of transplanted spruce seedlings in the nursery. Studies made include observations on survival and growth of seedlings under five different classes based on their hieghts viz. less than 7.5 cm; 7.5 cm to < 12.5 cm; 12.5 cm to < 17.5 cm; 17.5 cm to 22.5 cm and more than 22.5 cm. The performance of the seedlings below 7.5 cm in height in terms of both survival and growth was the poorest as compared to all other classes followed by the seedlings of 7.5 cm -< 12.5 cm height classes which also resulted in lower survival and poorer growth rate than those of the remaining three classes. Seedlings below 12.5 cm in height should, therefore, be culled at the time of transplanting.- Effect of Substrate Physical Factor on Mass Multiplication of Trichoderma harzianum in Management of Seedling Blight of Jute

Four substrates (wheat bran, rice bran, pulse bran and orange peel) singly and in combination with four oil cakes (mustard cake, groundnut cake, neem cake and linseed cake) were tested under variable temperature, moisture and pH levels to determine the best-suited physical conditions for the growth and sporulation of Trichoderma harzianum. The temperature of 30°C, moisture level of 60 percent and 5,5 of substrates pH has been found to best suited conditions, irrespective of substrates tested. Among the substrates, the wheat bran (agricultural byproducts), mustard cake (oil cakes) and wheat bran + mustard cake at 20 per cent has been shown to highly promising with highest number of population of antagonist. The formulation of T. harzianum has also found promising in increasing the germination of jute seeds and reduction in disease incidence of seedling blight disease. The wheat bran + mustard cake preparation was found superior over other combination of products.Keywords
