Response of sweet pepper (Capsicum animus L.) to spraying with different levels of nano-zinc and adding of poultry waste in the protected agriculture

Hussein Saad Hatim, Mohamed Tarkhan Abo Almeek


A field experiment was conducted in an unheated greenhouse of private sector farms in the Al-Mussaib project area (30 km north of Babylon province ) during the autumn season 2019-2020. To study the response of the sweet pepper plant. Capsicum animus L is a charisma cultivars for foliar spraying with different concentrations of nano zinc and addition of poultry waste mixed with soil, using the randomized complete block design (RCBD).The experiment included 48 treatments distributed into three replicates, and the averages were compared using the (L.S.D) test, the least significant difference at a probability level (0.05). Where the experiment included two factors, the first factor is the nano fertilizer (nano zinc sprayed on the leaves) with four concentrations (0,1,1.5,2 g. L-1) and the second factor is poultry waste (mixed with the soil) with four levels (0,12,24,36 tons.ha-1), The results indicated that the treatment of spraying with nano zinc fertilizer (2 g. L-1) was significantly excelled in increasing plant height , number of The number of branches, number of leaves and dry weight of the vegetative growth and increasing indicators of fruit number, fruit weight, early and total yield, with an increase of 115.45 cm, 19.23 branches.plant-1, 574.09 leaves.plant-1, 214.97 g.plant-1, 40.11 fruits.plant-1, 69.99 g, 0.90 kg.plant-1, 2.81 kg.plant-1 (respectively compared with control treatment, Also, the treatment of adding poultry waste at the level of (36 tons.ha-1) was significantly higher in increasing plant height rates, number of fruitful branches, number of fruiting branches, number of leaves, dry weight of the vegetative total, indicators of number of fruits, fruit weight, early and total yield above, as the increase rates reached 95.39 cm, 14.93 branches.plant-1, 454.34 leaves. plant-1, 184.70 g. plant-1, 33.82 fruits.plant-1, 65.39 g, 0.73 kg.plant-1, 2.27 kg. Nanoparticles and poultry waste at a concentration of (2 g.L-1 + 36 tons.ha-1), giving them the highest values for all the above trait.
