Evaluation of different dates of sowing on PDI of Sclerotinia stem rot of lentil

Pulse crops play an important role in Indian agriculture and economy and they are the major source of protein and complementary to cereals both in production and consumption. The fungus Sclerotinia sclerotiorum is one of the most destructive pathogens of lentils. Yield losses can be attributed to fungal growth within stems and resulting lodging, which leads to smaller and fewer seeds, premature ripening, shattered pods, loss of smaller, shrunken seeds during harvesting. The stem rot fungus overwinters as sclerotia in the soil, in stubble at the soil surface and mixed with seed. Sclerotia can remain viable in the field for five years or more. Each year some sclerotia will germinate when conditions are suitable but others will remain dormant. Germination is either myceliogenically which directly infect plants or may be carpogenic (spore-producing apothecia) heavy infections result from airborne spores produced by apothecia at the soil surface. The present investigation experiments were conducted to find out the effect of different dates of sowing on Sclerotinia stem rot incidence in lentil, starting form 05 October to 15 November at 10 days interval, irrespective of the year.

Effect of weather parameter on growth and development of wheat under different growing environment

The present investigation entitled “Effect of weather parameter on growth and development of wheat under different growing environment” was carried out during Rabi seasons of 2016-17 at Research and Instructional Farm of Indira Gandhi Krishi Vishwavidyalaya, Raipur to examine to validate the results of crop weather relationship of different wheat varieties grown under different growing environments in factorial Randomized Block Design. Some of the important points that emerged from the study are summarized in the present chapter. Among the growth parameters plant height recorded significantly higher in early date of sowing i.e. 1st December as compared to other growing environments (sowing on 11th and 12th December). The interaction of date of sowing with different variety of wheat crop were founds significantly influenced on plant height of crops at 40 DAS and 100 DAS stages. Significantly maximum number of leaves per plant was found with 1st December of sowing. The interaction effect of different date of sowing and varieties were found significant at 60 DAS. Number of tillers per plants were found significantly influenced due to different date of sowing and different variety at 40 DAS. At 20 and 80 DAS plant accumulated significantly higher value of dry matter in crop sown on 1st December 2016.

Influence of different dates of planting on growth, herb, oil yield and quality of essential oil of menthol mint (Mentha arvensis) in the North Indian Plain

A field experiment was conducted for two years (2007–2008 and 2008–2009) to study the effect of different dates of planting for three menthol mint (Mentha arvensis) cultivars (Saksham, Kushal and Kosi; developed by Central Institute of Medicinal and Aromatic Plants, Lucknow, India) on herb yield, oil yield and oil quality. All the cultivars produced higher herb and oil yields when planted on 18 February, compared with cultivars planted on other dates in both years. Average herb yield for Saksham increased by 12.89, 30.66, 54.01 and 85.71%, average herb yield for Kushal increased by 15.09, 30.57, 71.69 and 104.91%, and average herb yield for Kosi increased by 32.48, 53.28, 87.23 and 109.49% when planted on 4 January, 19 January, 3 February and 18 February, respectively, over cultivars planted on 20 December. Among the cultivars, Kosi produced a higher herb yield than Saksham and Kushal planted on 18 February. Saksham, Kushal and Kosi produced ∼89.39, 152.04 and 170.22% higher oil yield, when planted on 18 February over their respective planting date of 20 December. Maximum menthol content was recorded in cultivar Saksham when planted on 18 February and in Kushal and Kosi when planted on 4 March.

Effect of Different Dates of Dry Seeding and Staggered Nursery Sowing on Growth and Yield of Kharif Rice

A field experiment was conducted to study the effect of different dates of dry seeding and staggered nursery sowing on growth and yield of Kharif rice. The experiment was based on the difficulties faced by the farmers in the coastal areas of Andhra Pradesh and those who depend on canal irrigation and are located at the tail end areas. The experimental results have showed no difference among the methods of stand establishment in terms of yield. However, among the dates of sowing the delay in sowing beyond 30th July significantly reduced the grain yield and returns per rupee invested. It has been concluded that the rice crop may be established either by direct seeding or by transplanting nurseries but the sowing of the respective cultures should be done by the end of July for obtaining maximum yield and profits.
