Abstract Niger (Guizotia abyssinica Cass.) is an important minor oil seed crop grown in dry areas grown mostly by tribal and interior places as life line of tribal segment. Tribal people mainly use its oil for cooking purpose, above than that there were also other uses. Hence, the niger crop should be protected from the infection. The crop is affected by number of fungal diseases. Therefore, a field experiment was formulated for three years with the four replications at the Niger Research Station (NRS) at Navsari Agricultural University (NAU), Vanarasi, Navsari (Gujarat) on the foliar diseases of GN-1 variety of niger crop. In this experiment, six different fungicides along with one control have been evaluated to control the Alternaria and Cercospora leaf spot diseases, out of which all the fungicidal treatments were significantly superior over the control. Here, foliar spray on the incidence of diseases was compared with the control (without any treatment). All the fungicidal treatments were significantly superior over the control to reduce Alternaria and Cercospora leaf spot diseases of Niger crop. Treatment of Carbendazim + Mancozeb (0.2 %) with two sprays first from the initiation of the disease and second after the interval of 15 days recorded the lowest incidence of Alternaria (14.56) and Cercospora (14.94) leaf spot diseases of niger and recorded the highest seed yield 337 seed yield kg/ha along with the net return with cost benefit ratio graph.

Seed treatment with growth regulators, especially salicylic acid, is a promising alternative to the seed industry because it is an important inducer of resistance to diseases and pests, as well as acting significantly on quality and seed yield. The objective of this study was to evaluate the performance of rice seed treated with different concentrations of salicylic acid, as well as assess the crop yield and seed quality. The treatments consisted of increasing levels of 0, 50, 100, 150 and 200 mg.L-1 salicylic acid. To this was prepared a stock solution of salicylic acid and the highest concentration by successive dilution in distilled water, the other concentrations were obtained. The physiological quality of seeds produced was treated and evaluated by tests of vigor and germination, and after harvest were evaluated seed yield. It follows that treatment of rice seeds with salicylic acid concentrations up to 130 mg.L-1 at a dose of 2 mL.kg-1 seed does not affect the germination and affects the strength, however provides substantial increases in the yield of seeds. The seed treatment with salicylic acid has no influence on seed quality produced.

The Impact

When cool, wet conditions persist after planting, Pythium spp. can be an important constraint to stand establishment in field pea. Laboratory studies and field trials were conducted over 3 yr to assess the impact and evaluate the interactions of Pythium spp., metalaxyl seed treatment and damage to seed on seedling establishment, root rot severity and seed yield of field pea. Seedling emergence, seedling size, and seed yield were reduced by inoculation with Pythium spp. and by mechanical damage to the seed. Fungicide seed treatment reduced the impact of seed damage, but did not always restore seedling emergence and seed yield to the same level as from undamaged seed. Undamaged seed treated with metalaxyl was not affected by inoculation with Pythium spp. Differences among cultivars, although often significant, were small relative to the effect of seed injury. Laboratory studies showed a negative linear relationship between inoculum concentration and emergence from untreated seed. They also showed that Pythium spp. had a similar impact on seedling emergence in cool (20/10°C day/night) and cold (12/6°C) soils. This study showed that planting fungicide-treated, high-quality field seed was an effective means of maximizing emergence and stand establishment for commercial field pea production.

Seed Health

Loss of seed quality in soybean is a serious problem in tropical and subtropical region. Foliar application of salicylic acid (SA), GA3 and acetyl salicylic acid (50 ppm) at seedling and pod filling stage, K2HPO4 (2%), a-tocopherol (100 ppm) at flowering and pod filling stage was done on soybean varieties – NRC 7 and JS 335. Foliar application of SA showed positive effect on seed yield, seed health, germination and seed vigour during storage. Plant height was significantly improved by the GA3 spray in both the varieties. Significantly higher seed yield was obtained with foliar spray of a-tocopherol. Application of SA was found effective to protect plants from various diseases to get quality seed. a-Tocopherol and K2HPO4 treatment significantly reduced MDA production in seeds. a-Tocopherol application increased super oxide dismutase activity as a result the lipid peroxidation of seed during storage was significantly reduced. Application of a-tocopherol, K2HPO4 and salicylic acid improved the storage or keeping quality of soybean seed.

The Impact

A field experiment was conducted during rabi season of 2015-2016 at Navsari Agricultural University, Navsari to study the impact of cobalt application methods on chickpea yield, nutrient content and soil status. Four cobalt application methods with three levels of each were evaluated with one absolute control and one with seed priming of water were evaluated with randomized block design with three replications. Least level of seed treatment, soil application and foliar application of cobalt gave highest chickpea seed yield and decreased there after. As cobalt levels increased, NPK content and uptake are decreased linearly in all the methods except seed priming method, however cobalt content and uptake increased linearly by seed treatment and foliar application, on the contrary it decreased linearly by seed priming and soil application of cobalt. Soil application of cobalt at 50 g ha-1 recorded highest chickpea seed yield, residual NPK and Co and which can be useful for succeeding crop and this can be recommended from the cobalt nutrition point of view in plants and animals followed by seed priming at 1 ppm.
