DJELOVANJE DATUMA SIJANJA NA RAST I PRINOS SLATKE PAPRIKE (CAPSICUM ARUNUM L)

An experiment was carried out at the Horticultural farm of the Bangladesh Agricultural Research Institute, Joydebpur, Gazipur, during September 2006 to April 2007 to investigate growth and yield of sweet pepper as influenced by sowing date. There were seven levels of sowing date viz. September 1, September 15, October 1, October 15, October 30, November 15 and November 30. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on various parameters and statistically analyzed. The results of the experiment demonstrated that the majority of growth parameters and yield components were significantly increased at the earlier sowing (October 1). The highest yield (19.36 t/ha) of fruit was recorded from the earlier sowing (October 1) with the spacing (50×30 cm) which also gave the highest benefit cost ratio (4.58). Considering the yield of fruits per hectare, cost of production and net return, the treatment combinations of October 1 sowing appeared to be recommendable for the cultivation of sweet pepper.Na poljoprivrednoj farmi Zavoda za istraživanja u poljoprivredi Bangladeša u Joydepuru, Gazipur, obavljen je pokus od rujna 2006. do travnja 2007. da se istraži rast i prinos slatke paprike pod utjecajem datuma sijanja. Sijanje je obavljeno na sedam datuma, tj. 1. rujna, 15. rujna, 1. listopada, 15. listopada, 30. listopada, 15. studenog i 30. studenog. Pokus je postavljen u slučajnom potpunom bloku s tri ponavljanja. Podaci su bilježeni za različite parametre i statistički analizirani. Rezultati pokusa su pokazali da je većina parametara rasta i prinosa značajno porasla s ranijim sijanjem (1. listopada). Najveći prinos (19,36 t/ha) plodova zabilježen je za raniju sjetvu (1. listopada) uz razmak od 50x30cm, što je također dalo najviši/najbolji omjer koristi i troškova (4,58). Uzevši u obzir prinos plodova po hektaru, troškove proizvodnje i neto povrat sijanje 1. listopada može se preporučiti za uzgoj slatke paprike

EFFECT OF SPACING ON THE GROWTH AND YIELD OF SWEET PEPPER (Capsicum annuum L.)

A field experiment was carried out at the Horticultural farm of the Bangladesh Agricultural Research Institute (BARI), Joydebpur, Gazipur, during September 2006 to April 2007 to investigate growth and yield of sweet pepper as influenced by spacing. There were three levels of spacing viz. 50×50 cm, 50×40 cm, 50×30 cm. The experiment was laid out in a Randomized Complete Block Design (RCBD) with three replications. Data were recorded on various parameters and subjected to statistical analysis. The plant spacing had significant variation in almost all the growth and yield components except pericarp thickness. Number of branches per plant, number of leaves per plant, stem girth, number of fruits per plant, days to first harvest, fruit length, individual fruit weight, yield per plant were found to be significantly increased with the increasing of plant spacing but plant height at different stages, number of fruits per plot, days to 50% flowering, fruit breadth, yield per plot and yield per hectare were found to be significantly increased with the decreasing plant spacing. Considering the yield of fruits per hectare, cost of production and net return, 50×30cm spacing appeared to be recommendable for the cultivation of sweet pepper
