A factorial experiment was conducted during three successive cropping seasons to investigate the effects of nitrogen, phosphorus, potassium, and manure on the yield and maturity of broccoli (Brassica oleracea L. var. italica Plenck.). Terminal (central inflorescence), lateral (axillary stalk), and total yields were substantially increased by applications of nitrogen and phosphorus. For maximum yields, rates of 175 to 250 kg/ha of N and 100 to 150 kg/ha of P were necessary. Increases in lateral yields and total yields from high rates of nitrogen were obtained only when nitrogen was accompanied by adequate phosphorus. Yields of terminals were increased in only one of three seasons by added potassium. A manure treatment increased lateral and total yields in two seasons, and terminal yields in one season. Maturity was delayed by increasing the rates of nitrogen, and where no phosphorus was applied.

The effects of nitrogen, phosphorus, and potassium on the yield and maturity of cauliflower (Brassica oleracea L. ssp. botrytis cv. Snowball Y) were investigated at a total of nine locations during three successive cropping seasons. Yields were substantially increased at most locations by applications of nitrogen and phosphorus but were only slightly affected by applied potassium. Maturity was slightly delayed by a lack of phosphorus. Maximum yields were generally obtained where N was applied at 112–224 kg/ha, P at 49–98 kg/ha, and K at 93 kg/ha.

A factorial experiment was conducted during three successive cropping seasons to investigate the effects of nitrogen, phosphorus, potassium, and manure on the growth and yield of Brussels sprouts. Plant development was delayed by a lack of phosphorus. Nitrogen and phosphorus applications decreased the yields of small sprouts and increased the yields of those greater than 2.3 cm in diameter. Total marketable yields were substantially increased by nitrogen and phosphorus but were only slightly affected by rates of applied potassium. Yield increases from high rates of nitrogen were obtained only when accompanied by adequate phosphorus. A manure treatment slightly increased marketable yields but the effect was usually not significant.

The effects of nitrogen, phosphorus, and potassium on the yield and shape of rutabagas (Brassica napobrassica Mill., cult York) were investigated at three locations each year during three successive cropping seasons. Total and marketable yields were increased at most locations by applications of nitrogen and phosphorus, but applied potassium increased yields at only three locations. For maximum yields, rates of 90–112 kg/ha of N and 49–130 kg/ha of P were necessary. Where soil P levels were low, yield increases from applied N were obtained only when accompanied by adequate phosphorus. The ratio of the equatorial/polar diameters of the roots was increased by added N, and to a lesser extent, by applied P and K.

Effect of Alternaria blight (Alternaria brassiceae and A. brassicicola) on seed yield of cauliflower (Brassica oleracea L. var. botrytis) was studied during three consecutive growing seasons (2003-2004, 2004-2005, and 2005-2006) in winter under natural epiphytotic condition. There were two treatments viz. sprayed and unsprayed. BARI Cauliflower-1 was used as planting material and Rovral 50 WP (Iprodion) at 0.2% suspension was used as protective chemical to safe the crop against Alternaria brassiceae and A. brassicicola. Percent pod infection, pod area diseased, number of pods/plant and seed yield differed significantly between the sprayed and unsprayed (control) plots. Percent pod infection and pod area diseased ranged 35.3-62.4% and 94.7-97.6%, 1.9-2.2%, and 10.8-16.4% in sprayed and unsprayed plots in different, respectively. The number of pod/plant was 462-592 in sprayed and 281-395 in unsprayed plots. The seed yield/ha ranged 249.4-355.1 kg in unsprayed plots and 456.8-677.0 kg in Rovral sprayed plots. The seed yield increase were 59.6%, 171.4%, and 75.2% in 2003-2004, 2004-2005, and 2005-2006 cropping seasons, respectively.

Latar Belakang: Beta-karoten merupakan salah satu isomer karoten yang bisa ditemukan pada sayuran berwarna hijau tua atau kuning tua (seperti wortel dan brokoli). Brokoli merupakan sayuran yang memiliki kandungan beta-karoten yang cukup tinggi, yaitu 623 IU/100 gram. Namun, proses pengolahan brokoli menjadi hidangan dapat menurunkan kandungan beta-karotennya. Tujuan: Mengetahui pengaruh teknik pengolahan terhadap kandungan beta-karoten pada brokoli. Metode: Jenis penelitian ini adalah observational di laboratorium. Penelitian ini menggunakan rancangan acak sederhana dengan dua kali pengulangan dan satu unit percobaan. Teknik pengolahan yang dilakukan adalah merebus, mengukus, dan menumis. Brokoli mentah digunakan sebagai kontrol. Penelitian dilakukan pada bulan Februari–Maret 2017. Analisis kadar beta-karoten dilakukan di Laboratorium Chem-mix Pratama Yogyakarta dengan metode spektrofotometri. Hasil: Kadar beta-karoten tertinggi terdapat pada brokoli mentah diikuti dengan brokoli yang ditumis, dikukus dan direbus. Persen penurunan kadar beta-karoten yang direbus, dikukus dan ditumis dibandingkan dengan brokoli mentah masing-masing sebesar 45,87%, 33,52% dan 22,25%. Ada penurunan kadar beta-karoten yang signifikan setelah direbus, ditumis, maupun dikukus dibandingkan dengan brokoli segar (p<0,05). Kesimpulan: Kadar beta-karoten pada brokoli mengalami penurunan setelah dilakukan pengolahan dengan cara direbus, dikukus, dan ditumis. Merebus mengakibatkan penurunan kadar betakaroten terbanyak dibandingkan dengan kedua proses lainnya.
