Abstract:
In different growth period,we spray different concentraction mangic acid solution on the surface of leaves of Pisum Sativum L.. The result show that the activity of SOD, CAT is promoted,the content of MDA and the speed of O~(·-)_2 production are reduced in seedling, buding and flowering period.We find that if spraying 0.1%～0.2% mangic acid solution on the surface of leaves in seedling, buding and flowering period,the production of Pisum Sativum L.was promoted.Cite
Two field experiments were carried out at Sids Horticulture Research Station, Beni Sueif Governorate, Agriculture Research Center, Egypt during the two successive winter seasons of 2015/2016 and 2016/2017.To study the effect of foliar spraying with two concentrations from three stimulate substances i.e.Salicylic acid at a rate of 0.5 and 1 g/ L, Selenium at a rate of 5 and 10 mg/ L, Green miracle at a rate of 3 and 6 cm 3 / L beside the control (spraying with tap water) and their interaction on growth characters, pollen grains viability %, yield and its components as well as some chemical constituents in the leaves and the seeds under low temperature stress in the late peas plantations which prevailing under the middle Egypt region conditions during this period of the year for two peas (Pisum sativum L.) cultivars i.e.Entsar 1 and Master B. The experimental design was splitplot; two pea cultivars were devoted in the main plots and foliar applications of three stimulate substances at the two concentrations of each of them arranged in sub plots.Seeds were sown in the 1 st week in December during the two seasons.The results showed that the superiority of Entsar 1 cultivar in the studied characters of growth i.e. plant height, number of branches and dry weight/ plant in addition to the percentage of the vitality of the pollen grains, total pods yield (ton/ fed) and its components as well as the chemical content of leaves and seeds i.e. chlorophyll, total sugars, proline, nitrogen, phosphorus and potassium in leaves as well as total sugars and protein in seeds as compared with Master B cultivar.The results also showed that the foliar spraying with the Green miracle at a concentration of 3 cm 3 / L which was the best stimulant substance markedly improve most of the studied characters.The results of the interaction between the two factors had a significant effect on the studied characters of growth, pods yield and its components as well as the chemical content of leaves and seeds under these conditions.The best results were obtained from foliar spraying of Entsar 1 cv.by the Green miracle substance at a concentration of 3 cm 3 / L followed by foliar spraying with the highest concentrations of Selenium and Salicylic acid, respectively.

A field experiment was conducted at Agricultural Research Station (Agriculture University), Kota (Rajasthan) During Rabi seasons (2019-20). The experiment comprised of 3 fertility levels (i.e.75%, 100% and 125%) were kept in main plots and 5 levels of foliar nutrition (i.e. water spray, 2 % Neem coated urea, NPK 19:19:19, NPK 17:44:0 & NPK 0:0:50 @ 0.5 % PF& PI in sub plots. Fertility level was drilled 4-5 cm deep into the soil before Field pea sowing in earmarked strips and subsequently foliar nutrition were sprayed at critical stages i.e. flower initiation and pod development. Result revealed that fertility level 25 kg ha-1 N, 50 kg ha-1P, 25 kg ha-1 K2O kg ha-1, 25kg ha-1 S and 25kg ha-1ZnSo4 kg ha-1 before sowing recorded significantly higher pods plant-1 (62.2), grain yield (2310 kg ha-1) and straw yield (3555 kg ha-1) respectively, while, maximum biological yield (5865 kg ha-1) was fetched with fertility 125% RDF. Foliar application of NPK (19:19:19) @ 0.5 % at flower initiation & pod development stages recorded significantly higher pods plant-1 (63.2), grain yield (2261 kg ha-1), straw yield (3436 kg ha-1) and biological yield (5697 kg ha-1) being on par with NPK 19:19:19 respectively.

Foliage spraying was used at seedling,blossom and pod stage of peanut respectively,the results showed that the photosynthetic indexes were obviously increased by spraying of calcium superphosphate and boric acid at blossom,which improved the photosynthetic efficiency and yield of peanut.At the same time,the change of content of plant hormones at blossom stage was studied,the results showed that the contents of Zeatin and IAA were evidently increased by spraying of calcium superphosphate and boric acid,which promoted the growth of peanut at blossom.

Field pea (Pisum sativum L.) seed contains a large amount of proteins, amino acids, sugars, carbohydrates, vitamins A and C, calcium and phosphorous, and hence it is widely used for many purposes. Although field pea has moderate requirements for its growth, it is sensitive to increased salt content in soil. This research included eight varieties (Javor, Jantar, Partner, Kristal, Pionir, Junior, Trezor, Dukat) developed at Institute of Field and Vegetable Crops in Novi Sad. Sodium chloride solutions of various concentrations (0, 50, 100 and 150 mM) were added in growing media to simulate saline conditions. The following were subsequently determined: seed germination, seedling length, fresh and dry weight of seedlings and 1000-seed weight. Among the analyzed varieties, variety Jantar expressed a high level of tolerance to increased salt content in growing media under laboratory conditions.

The effect of foliar sprays of plant growth regulators (PGRs), viz. NAA (10, 15 and 20 ppm), GA3 (50, 75 and 100 ppm) and kinetin (10, 15 and 20 ppm) at 25 and 35 DAS was evaluated on growth, yield and seed quality attributes in garden pea (Pisum sativum var Hortense) cv. Pusa Pragati under field condition. Plant morphology was affected by spray of the three PGRs at vegetative stage. Plant height increased with increase in concentration of GA3 and kinetin, albeit NAA. However, GA3 did not influence the number of primary branches/plant, which were significantly increased by kinetin and NAA. GA3 had a profound effect on hastening the initiation of flowering by 3-5 days over water sprayed control, whereas other plant growth regulators did not affect the days to flowering. The seed quality parameters did not increase significantly on increasing the concentration of PGRs except seedling length and vigour index I. Application of GA3 led to best quality of harvested seed. Protein, N, P, Cu, Fe and Mn content of seeds increased with increase in concentration of kinetin and NAA. GA3 had no significant effect on nitrogen and crude protein content of seed but markedly increased K, Cu, Fe and Mn content. Maximum P content in seed was observed in plants sprayed with NAA. No significant change was observed in Zn content with either plant growth regulator.

Two field experiments were carried out in winter seasons of 2012/2013 and 2013/ 2014 to study the effect of foliar fertilizer with nitrofoska and treating seeds with bio-fertilizers , i.e. nitrobein and potassiomag on plant growth, chemical composition and green pod yield and its components, as well as, pod quality (pod physical characters and nutritive value of seeds) of pea cv.Lincoln.The results showed that foliar fertilization with nitrofoska and bio-fertilization with nitrobein increased most of plant growth traits, minerals content of shoots (N,P and K as a concentration), yield and its components, as well as physical pod characters and nutritive value of seeds (N, P, K contents, protein, ascorbic acid, TSS and total carbohydrates), followed by nitofoska + potassiomag, then nitofoska + nitrobein+potassiomag, respectively, in most cases.Conclusively, it could be concluded that the combination treatment between nitrofoska and nitrobein, followed by nitrofoska and potassiomag , as well as, nitrofoska + nitrobein + potassiomag, respectively, enhancing the most studied characters of peas.
