Response of Sweet Pepper (Capsicum Animus L.) to Different Levels of Nano-Zinc and Poultry Manure

Abstract

An experiment was conducted in the unheated greenhouse in greater Mussaib project north of Babylon province at 30km in autumn season (2019-2020), to evaluate the effect of the spraying with different concentrations of nano zinc and poultry manure addition on pepper plant (Capsicum animus L.) The Randomized complete block design (RCBD). was used with three replicates per treatment, mean value were compared using the (L.S.D0.05)test. First factor was Nano-zinc fertilizer with 4 concentrations (0 ,1 ,1.5 ,2 g. L-1), while second factor was poultry manure with 4 treatment (0 , 12 , 24 , 36 tons.ha-1), The results indicated that spraying treatment with Nano Zn fertilizer (2 g. L-1) showed a significant increase in plant height , branches No., leaves No., and plant dry matter in addition to increase fruit No. fruit weight, early and total yield, wich recorded 115.45 cm, 21.16 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 poultry manure adding at (36 tons.ha-1) was significantly increasing the parameters above with average value 95.39 cm, 21.03 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 respectively. The interaction treatment between Nano-Zn and poultry manure (2 g.L-1 + 36 tons.ha-1), gave the highest values for all the above parameters .
