Results showed that yield of brown sarson (Brassica campestris L. var. dichotoma Watt.) was curvilinearly related to the irrigation levels, peaking at 21.8 cm of water. Yield responses to nitrogen were greater with than without irrigation, were not influenced by row spacings at low levels of water but were greater with low than with the high density plantings (narrower spacings) at the high levels of water. Oil content was increased by irrigation, increased by nitrogen at the low levels but decreased at the high levels (48 and 60 kg/ha), and was directly related to the row spacing under restricted water supply and inversely related to row spacing under adequate water supply.

The inheritance of siliqua strength was studied in Brassica campestris L. using F1, F2, and backcross generations of crosses between cv. Torch (shatter susceptible) and var. Yellow Sarson and var. Brown Sarson (shatter resistant) accessions. Shatter resistance (high siliqua strength) was recessive in all crosses. Crosses involving DS-17-D (var. Brown Sarson) indicated that siliqua strength is most likely controlled by two genes that show dominant epistatic interaction. Crosses of IB-5 and B-46 (both var. Yellow Sarson) each with cv. Torch indicated the likelihood of three genes controlling siliqua strength, two of which appeared to be epistatic over the third gene when dominant. In these crosses, the multivalve character appeared to be controlled by three genes, two of which were epistatic over the third gene resulting in multivalve character when the former two were recessive. Segregation for siliqua strength in the var. Yellow Sarson crosses was not independent of segregation for multivalve character.Key words: Brassica, siliqua strength, shatter resistance, Sarson.

SummaryAn experiment was conducted during the rabi seasons of 1980–1 and 1981–2 to study the effect of exchangeable sodium percentage (ESP) of 87, 62, 44, 34 and 27 on growth, yield and chemical composition of toria (Brassica campestris var. Toria), raya (Brassica juncea L.) rapeseed (Brassica campestris var. Brown Sarson) and taramira (Eruca saliva). Number of branches per plant, number of siliquae per plant and seed yield of these crops were highest at 27 ESP. Increasing ESP decreased N, P, K, Ca, Mg, Fe, Zn, Cu and Mn concentrations and decreased that of Na in seed and stover. These crops can be grown successfully up to about 44 ESP without significant reduction in yield. Raya and rapeseed produced higher yields than the other oilseed crops on sodic soil.

Developing Seeds

The effect of sulfur (S) fertilisation on oil accumulation, acetyl-CoA concentration, and activity of acetyl-CoA carboxylase (EC 6.4.1.2) was determined in the developing seeds of rapeseed (Brassica campestris L. cv. Pusa Gold) grown in the field with and without S. The period between 14 and 35 days after flowering (DAF) was identified as the active period of oil accumulation in the developing seeds of rapeseed. The accumulation of oil was preceded by a marked rise in acetyl-CoA carboxylase activity and acetyl-CoA concentration, which declined rapidly when oil accumulation reached a plateau. Starch and soluble sugar content decreased, while protein content increased during the period of active oil accumulation in the developing seeds (i.e. 14–35 DAF). Sulfur fertilisation significantly (P < 0.05) enhanced the oil accumulation in the developing seeds at all the growth stages except at 7 DAF. The increase in the oil content was 13.0–52.0% with S fertilisation over the control treatment. Sulfur fertilisation also increased acetyl-CoA concentration, acetyl-CoA carboxylase activity, and soluble protein, sugar, and starch content in the developing seeds. It is suggested that the increase in the oil content with S fertilisation may be associated with increases in acetyl-CoA carboxylase activity through the enhancement of acetyl-CoA concentration. Further, the increased sugar content due to S fertilisation provided enough carbon sources for oil biosynthesis.

Rape (Brassica campestris L.) is well adapted to the Bangladesh climate and is an important oil crop of the northern part of Bangladesh. It requires a shorter growing season than any other crop of this kind but is less resistant to drought, which causes considerable damage to the crop by reducing total green area during late December and January and results in a poor yield. Considerable increase of rape-seed production will be possible through the elimination of drought by irrigation, the right supply of nutrients and application of proper cultural practices. We report here on studies of the effect of fertilizer under irrigated and non-irrigated conditions on the seed yield, oil content and some seed yield associated characters of rape and the importance of irrigation in rape cultivation in Bangladesh.

Rapeseed-mustard crops in India comprise traditionally grown indigenous species, namely toria (Brassica campestris L. var. toria), brown sarson (Brassica campestris L. var. brown sarson), yellow sarson (Brassica campestris L. var. yellow sarson), Indian mustard (Brassica juncea L. Czern and Coss.), black mustard (Brassica nigra) and taramira (Eruca sativa/ vesicaria Mill.), which have been grown since about 3,500 BC along with non-traditional species like gobhi sarson (Brassica napus L.) and Ethiopian mustard or karan rai (Brassica carinata A.
