Eff?ct of Wat?r Str?ss on the Growth and Yield of Sweet Pepper (Capsicum annum L.) und?r Gr??nhous? Conditions

摘要

An ?xp?rim?nt was conduct?d to ch?ck th? ?ff?ct of diff?r?nt l?v?ls of irrigation tr?atm?nts on th? growth and yi?ld of sw??t p?pp?r on a sandy soil, und?r gr??nhous? conditions by using drip irrigation syst?m having flow rat? of dripp?rs 2 lit?rs p?r hour (LPS). The field study was carried out on a randomized complete block design (RCBD) having seven different rates of irrigation treatments with four replications. The irrigation water applied in such a way that (T₁ = one time, T₂ = two times, T₃ = three times, T₄ = four times, T₅ = five times, T₆ = six times, and T₇ = seven times) application per day. Th? r?sults r?v?al?d that diff?r?nt l?v?ls of irrigation wat?r application brought a positiv? ?ff?ct in sw??t p?pp?r production. Amongst all th? tr?atm?nts, T₅ was obs?rv?d to b? mor? suitabl? and ?conomical as it took l?ast days to d?v?lop flow?rs (24.41 days), giv? mor? numb?r of fruits p?r plant (18.51 fruits), high?st fruit l?ngth (8.20 cm), high?st fruit diam?t?r (7.09 cm), high?st fruit w?ight (103.80 g), and high?st fruit yi?ld (7.62 tons donum^-1) r?sp?ctiv?ly. How?v?r, tr?atm?nt T₁show?d inad?quat? r?sults r?garding all th? param?t?rs. R?sults sugg?sts that th? fiv? tim?s application of wat?r of thr?? minut?s long duration p?r day to th? sw??t p?pp?r plants, with 15 minut?s gap in b?tw??n ?ach wat?r application w?r? found suitabl? for b?st possibl? growth and yi?ld of sw??t p?pp?r und?r gr??nhous? conditions using drip irrigation syst?m.
