Production of inulin from yam bean tubers by ultrasonic assisted extraction (UAE) was optimized by using response surface methodology (RSM) and genetic algorithms (GA). Yield of inulin was obtained between 11.97%–12.15% for UAE and 11.21%–11.38% for microwave assisted extraction (MAE) using both the methodologies, significantly higher than conventional method (9.9 %) using optimized conditions.

Common scab caused by Streptomyces scabies (Thaxter) Waksman & Henrici is an important disease worldwide, and can cause significant reduction in the economic value of potato. The management of the disease can be done through conventional methods, biological chemical and cultivation of resistant variety. However, resistance against pathogen is not a permanent solution and fungicidal is not ecofriendly and economical. But new search, induce resistance has taken great attention for plant disease management in near future.

The aims were to evaluate the impact of organic, conventional and traditional production systems on yield, proximate composition and mineral content of tubers and soil physico-chemical and biological properties in greater yam (Dioscorea alata). Organic farming (35.14 t ha-1 ) produced significantly higher yield over conventional practice (28.17 t ha-1 ) by 24%. A net profit of Rs 3,16,534 ha-1 , which was 38% higher over chemical based farming was obtained under organic management in greater yam Tuber quality was improved with slightly higher dry matter, starch and crude protein contents.

The production potential of root vegetables depends on many factors, amongst them; plant growth regulators appreciably influence the growth, yield and quality of produce. They play an important role in producing high value root vegetables and increasing the yield. They promote root growth, increase the number of flowers, fruit size and induce early and uniform fruit ripening. Foliar application of plant growth regulators is reported to improve tuber yield, dry matter and quality characters like starch, total sugars and beta carotene content.

An experiment was conducted with 32 cultivars of dahlia (Dahlia variabilis L.) to study correlation and path analysis among the yield attributing traits and their effect. Correlation among component characters showed that flower yield per plant had a highly significant positive genotypic correlation with leaf area index (0.617), crop duration (0.771), flowering duration (0.800), tuber weight (0.668) and change in fresh weight at day 3.

Potato is a cool weather crop, with temperature being the main limiting factor on production; however it grows under a diverse range of climatic conditions. The vegetative growth of the plant is best at a temperature of 24°C while tuber development is favoured at 18°C. Hence, potato is grown as a summer crop in the hills and as a winter crop in the tropical and subtropical regions.

Arbuscular mycorrhizal fungal symbiosis has a significant impact on sustainable growth and development of various plants as they help to acclimatize with biotic and abiotic conditions. A study was conducted to determine the effects of various mycorrhizae based products at different concentrations on yield and quality of potato (Solanum tuberosum L.) cv. Kufri Sindhuri during Rabi 2016-17 at Vegetable research farm, Department of Horticulture, Institute of Agricultural Sciences, BHU, Varanasi.

Improving and maintaining soil quality for enhancing and sustaining agricultural production is of utmost importance for India’s food and nutritional security. Permanent Manurial Experiments (PMW) are ideal sites for studying management induced variability in crop production and soil health. The biological activity of a soil is the function of number of organisms present in soil and their physiological efficiency. Soil microbial diversity is one of the most important microbial parameters in soil.

Cassava (Manihot esculenta Crantz) is a perennial shrub and a tuberous root crop well adapted to poor soils and is relatively tolerant to drought, the crop is usually grown under marginal soil and climatic conditions and often with very limited inputs of fertilizers and pesticides. In India, cassava is cultivated in varied agro climatic and pedogenic environments. In Tamil Nadu, it is cultivated mainly for industrial uses, cassava is grown in black soils (Vertisols) and red soils (Alfisols).

To view the effect of depth of planting on growth and yield parameters of potato (Solanum tuberosum L.) crop, the experiments were conducted at Students Research Farm, Khalsa College Amritsar. The experiments were conducted at three different depths of planting as treatments viz., D1 (3”), D2 (5”) and D3 (7”) and each treatment was replicated three times. The data had been recorded at their respective stages of growth and total yield were measured at the end of the season of the potato crop. It was found that maximum number of stems per plant was 6.

A field experiment was conducted to score the comparative efficiency of biocontrol agents in the management of root borne diseases of Coleus forskohlii (cv.K-8). The crop has a great potential demand for forskolin (Diterpene) with wide application in treating many human diseases. However, the crop has become unpopular among farmers due to the susceptibility to many diseases of which root rot and wilt is the most serious causing loss in tuber yield and makes the crop uneconomical.

A field experiment was conducted to assess the combined effect of bioinoculants on nutrient uptake, forskolin content (diterpene) and tuber yield of Coleus forskohlii (cutivar; K-8). The microbial inoculants such as Azotobacter chroococcum, Bacillus subtilis, Pseudomonas fluorescens, Glomus fasciculatum (VAM) were used. Bioagents such as Trichoderma harzianum and Pseudomonas fluorescens were used. Bioinoculants were examined along with graded levels of recommended dose of N and P2O5 with 100% K2O fertilizers. Nutrient uptake showed significant difference among the treatments.
