Effect of Nutrient Levels and Plant Growth Regulators on Growth Parameters of Pearl Millet

The influence of plant growth regulators on growth of wheat seedlings and their foot and root diseases severity was studied. It was established that plant growth regulators has improved the growth parameters of wheat plants at early stage of ontogenesis, thus demolishing the negative influence of the diseases on these indexes.

Sowing Seed

Background: Pre-sowing seed hardening and foliar spray with plant growth regulators is an easy, low cost and low risk technique and also an alternative approach recently used to mitigate the effect of abiotic stresses in agricultural production. Methods: The mung bean var. GAM-5 was treated with seed hardening treatments and also for foliar spray using CaCl2 2% and 1%, CCC 500 mg/L, CCC 1000 mg/L, NAA 25 mg/L, NAA 50 mg/L. during summer season of 2015-16 and 2016-17. The trial was laid out in RBD with three replications and sixteen treatment combinations. Result: The results indicated a significant improvement in morpho-physiological growth parameters, dry matter production and thereby yield potential increased due to the application of plant growth regulators and agrochemical under field conditions. Among the different treatments, seed hardening with 2% CaCl2 + 1% foliar spraying at 30 DAS (T11) treatment significantly improved most of morpho-physiological parameters and thereby yield in green gram followed by the seed hardening treatments of Cycocel 1000 mg/L + foliar spraying at 30 DAS (T13) and seed hardening with NAA 50 mg/L + foliar spraying at 30 DAS (T15).

Yield And Quality

Background: The South Gujarat hilly part is considered to be a non-traditional area of strawberry cultivation in India. The poor farmers of this region are cultivating strawberries under open field condition. Both, the yield and quality of strawberry fruits of this region are not up-to-the-mark as there in other parts of the country. Hence, a low-cost improved production technology is required to maximize yield as well as improve the quality of strawberry fruits. Method: Uniform runners of strawberry cv. Winter Dawn were grown in open field under paddy straw as bedding material. Foliar spraying of plant growth regulators viz. NAA (50, 75, 100 and 125 mg l-1) and GA3 (50, 75, 100 and 125 mg l-1) were done at 30 and 60 days after planting. The experiment was laid out in randomized block design with control plants receiving no spray treatments and replicated thrice. Result: The plant growth parameters like plant spread, number of leaves, number of crowns, leaf area, length of petiole, number of runners were recorded maximum with the application of 100 mg l-1 GA3. This treatment was also found to be the best in respect of number of flowers, number of fruits, fruit weight, marketable and total fruit yield of strawberry. Strawberry fruits with the highest total soluble solid, ascorbic acid, reducing sugar, non-reducing sugar and total sugar content were recorded in the plants which received 125 mg l-1 NAA. However, the plant growth regulator treatments failed to influence any significant effect on days taken to 50.0% flowering, fruit firmness and acidity content of strawberry fruits.
