International Business World News. Torrent Pharma. Market Watch. Pinterest Reddit. By Sutanuka Ghosal. Domestic vegetable seeds industry is expected to double from the current size to around Rs. This growth will be necessitated by the estimated growth in vegetable production required to meet future demand, and driven by greater use of hybrid seeds, which as of now have low penetration , says an ICRA note. However, given the constraints on increasing the area under cultivation, the growth would come through productivity augmentation of which a major part has to be driven by greater adoption of hybrid seeds in cultivation of vegetable crops.

ICRA estimates that with the growth in volumes as well as value on the back of hybridisation , the size of the vegetable seeds industry would double from the current levels to around Rs. This growth is contributed both by increase in the area under cultivation and improvement in yields.

The Governments at the Centre as well as the state level have taken various initiatives to boost the production of vegetable crops. As against general nutrition guidelines recommending average per capita consumption of kg of vegetable per annum, the production in the country is adequate at per-capita level of around kg per annum. However, still there is a relative shortfall of vegetables in meeting the required nutritional need of the population due to mismanagement at various levels.

New location-specific high yielding hybrid varieties should be developed given the diverse agro-climatic conditions in the country. Investment in hybrid seeds research and development is a key element and should be stepped up. Follow us on. Download et app. Become a member. Mail This Article. My Saved Articles Sign in Sign up.

Domestic vegetable seeds industry expected to double in 5 years - The Economic Times

Grafting for the use of root systems as biological filters to prevent contaminants' penetration into vegetable plants. A major part of the Mediterranean region is characterized by water scarcity, with long dry summers and short wet winters. To satisfy the demand for food and to combat desertification in this region, marginal water sources, such as treated domestic sewage effluent and saline water, are being increasingly used for irrigation Ben-Hur, Similarly in effluents, the EC and pH values, and the concentrations of microelements such as heavy metals and B, and of nutrients and dissolved organic matter are, in general, significantly higher than in fresh water.

Long-term use of these types of water for irrigation could increase the accumulation and concentrations of microelements and saline elements Na, Ca, Mg, and Cl in the soil Ben-Hur, ; Feigin et al. Absorption of these elements by the plants could affect their growth and yield, and increase the possibility of contaminants entering the food supply chain. Consumers are becoming increasingly concerned about because of the possible adverse effects on environmental quality and human health.

This is particularly true for , which are often regarded as a safe and nutritious food source. Edelstein et al. The effects of plant grafting on microelement concentrations in the fruit of melon plants under field conditions were studied in field plots with clay soil. The field plots were irrigated with secondary effluent for 4 years, and melon non-grafted plant and grafted plant were grown in these plots.

The concentrations of various microelements in the fruits of the grafted and non-grafted melon plants are presented in Fig. To determine the mechanisms responsible for the lower microelement concentrations in the fruits of the grafted plants, detailed experiments were conducted in the greenhouse. B can be absorbed by the root cell symplast or loaded into the xylem by means of two main transport mechanisms: passive diffusion through the lipid bilayer, and passage through proteinaceous channels in the cell membrane Dannel et al.

To determine the differences in selectivity of the root systems of melon and pumpkin TZ to B absorption, their seedlings were planted in pots in the greenhouse, and irrigated with fresh water containing various concentrations of B. Thirty days after planting, and immediately after an irrigation event, stems 3 cm above the surface of the growth medium were cut and the xylem sap exudates collected.

B concentration was determined in each collected sap sample. The B concentrations in the melon sap exudates were higher than those in the pumpkin sap exudates Fig.

The B-exclusion hypothesis is supported by other studies: Dannel et al. Dordas et al. The plasma membrane and partly through proteinaceous channels. Dordas and Brown examined B transport in squash plants, and suggested that both of these mechanisms were possible. Vegetative growth, fruit yield and fruit sizes of the grafted plants were higher than those of the non-grafted plants Fig.

The differences in yield parameters were probably due to the higher salt tolerance of the grafted vs. Fernandez-Garcia et al. Likewise, Romero et al. The concentrations of Ca, Na, Mg, and Cl- in the leaves, stem, and fruit tissues of a non-grafted melon cv.

Arava plant and melon grafted onto pumpkin rootstock TZ grown in field plots in the experimental station in Akko are presented in Table 1. These plants were irrigated with secondary effluent. The concentrations of all saline elements except Mg in the stem and leaves were higher in the non-grafted vs. The largest difference between the non-grafted and grafted plants was in their Na concentration, which was one order of magnitude lower in the grafted plant tissues than in the non-grafted ones.

Two mechanisms might explain the decrease in shoot Na concentration in plants with pumpkin rootstocks: i Na exclusion by the pumpkin roots, and ii Na retention and accumulation within the pumpkin rootstock. Quantitative analysis performed by Edelstein et al. Na retention by the pumpkin rootstocks decreased its amount in the shoot by an average In contrast, no retention of Na was found in plants grafted on melons.

Intensive agriculture has increased the use of toxic chemicals on cultivated lands. In addition, to satisfy the demand for food in arid and semiarid regions, the use of marginal water sources, such as treated domestic sewage effluent and saline water, for irrigation is on the rise.

These can enhance soil and water contamination, and the possibility of toxic microelements and saline elements entering into the food supply chain via plants. From laboratory, greenhouse and field experiments, it can be concluded that grafting of vegetable plants can be used as a technique to prevent the entry of toxic microelements and saline elements into the food chain.
