Mentha Piperita

The purpose of the present work was to evaluate the vegetative growth of Mentha piperita L. cultivated under different water availability, as well its influence in content, chemical composition and in vitro antioxidant activity of its essential oil. Plants were propagated by mother plants microcutting and scions were transplanted to 5 L pots with soil and cattle manure. Afterward, were kept at field capacity for 30 days and under treatment for 40 days. It was treated with different levels of water deficit treatments: (T1): 100 of field capacity (FC); (T2): 80 of FC; (T3): 60 of FC; (T4) 40 of FC with 5 blocks. Vegetative growth was evaluated by dry matter contents of all part of plants and by root/aerial rate. The essential oil of the leaves was extracted by hydrodistillation, analyzed by GC-FID and GC-MS and in vitro antioxidant potential was evaluated. A significant decrease in the dry matter of leaves and stems accompanied with a decrease in the roots dry matter was observed with an increase in the water stress. Quantitative chemical differences were observed in the chemical composition of the essential oil, according water availability. Total antioxidant activity showed a gradual increase as water stress progressed.

This investigation was conducted in a private farm, Samannoud district, El-Gharbia Governorate, Egypt, during two successive seasons of 2017 and 2018 to study the effect of organic fertilizers and foliar spray of amino acid on vegetative growth, fruit yield, chemical composition and capsaicin content of hot pepper (Capsicum annum L var. Minimum) plant. The experiment included 13 treatments obtained from cattle manure at rates of 60 and 30 N-units per fed. combined with amino acid at 0, 100 and 200 ppm as well as chicken fertilizer at rates of 60 and 30 N-units per fed combined with amino acid at 0, 100 and 200 ppm, besides the treatment of NPK at recommended dose as a control. A complete randomized block design with three replicates was adopted. The obtained results showed that, the highest values from vegetative growth parameters,  fruit yield, chemicals composition and capsaicin content were obtained from plants treated with cattle manure full dose + 200 ppm amino acids , followed by plants treated with chicken manure full dose + 200 ppm amino acids compared with all treatments except plant height, the highest value was obtained from plants treated with NPK (control) in the two seasons. Amino acid had a great effect when added with organic fertilization, whether cattle manure or chicken fertilizer at a concentration of 100 or 200 ppm. Based on the previous results, it could be recommend that spraying amino acids (glycine and glutamine) at the rate of 200 ppm along with organic fertilizers at the rate of 60 nitrogen units per feddan get the highest fruits yield, Vitamin C and capsaicin of hot pepper.

Tagetes Erecta L

African marigold (Tagetes erecta L.) is one of the important commercial flower crop grown exclusively for their vibrant blooms. An experiment entitled “Effect of organic manures with foliar application of fish amino acid on growth and yield of African marigold (Tagetes erecta L.) was carried out in the department of Horticulture, Faculty of Agriculture, Annamalai University, Annamalainagar during (2018–2020). The twelve treatments includes organic inputs such as farmyard manure (25 t ha-1), vermicompost (5t ha-1), oilcake (2 t ha-1) along with foliar application of two levels of fish amino acid @ 2% and 4 % . The treatments were studied under randomized block design (RBD) with three replications. Among the twelve treatments, the performance of plants treated with (FYM @ 25t ha-1+ Vermicompost @ 5 t ha-1 + FAA @ 4%) resulted in superior plant height (63.42 cm), plant spread (54.31cm), number of primary branches (13.68), secondary branches (24.17) , number of leaves (154.86 ), dry matter production (118.23 g plant-1). Hence it is concluded that combined application of organic manures and fish amino acid had a good synergetic effect on vegetative growth of African marigold.
