The Impact

The present study aimed to evaluate the potentiality of three seaweeds, which belong to different algal taxa (green alga Ulva lactuca Linnaeus, brown alga Cystoseira spp., and red alga Gelidium crinale (Hare ex Turner) Gaillon) as bio-fertilizers to improve the growth and yield of canola (Brassica napus L.) plants under greenhouse conditions. Furthermore, the impact of seaweeds in alleviating the effects of salt stress (75 and 150 mM NaCl) on canola plants was also investigated. The three examined seaweeds (applied as soil amendments) successfully alleviated the harmful effects of salinity on canola plants by significantly reducing the inhibition of chlorophyll a, b, total carbohydrate accumulation, and growth promoting hormones, while increasing antioxidative compounds, such as phenols, flavonoids, anthocyanin, and osmoprotectants, including total carbohydrates and proline. Phytochemical analysis of the three examined seaweeds suggests that their stimulatory effect on growth and productivity under normal and salinity growth conditions may be linked to their constituents of a wide variety of growth promotive hormones, including indole acetic acid, indole butyric acid, gibberellic acid, cytokinins, total carbohydrates, and phenolic compounds. U. lactuca was found to be the best candidate to be used as a bio-fertilizer to improve canola growth, yield, and salt stress tolerance.

Lysimeter experiments were conducted under greenhouse conditions to investigate canola (Brassica napus L.) plant water use, growth, and yield parameters for three different water table depths of 30, 60, and 90 cm. Additionally, control experiments were conducted, and only irrigation was applied to these lysimeters without water table limitations. The canola plant’s tolerance level to shallow groundwater was determined. Results showed that groundwater contributions to canola plant for the treatments at 30, 60, and 90 cm water table depths were 97%, 71%, and 68%, respectively, while the average grain yields of canola were 4.5, 5.3, and 6.3 gr, respectively. These results demonstrate that a 90 cm water table depth is the optimum depth for canola plants to produce a high yield with the least amount of water utilization.

SummaryThe effects of drilling date (18 August–22 September) on the growth and yield of oil-seed rape (Brassica napus) was studied in a series of five experiments over three seasons. Autumn and winter growth of the crop, as measured by dry weight of tops and leaf area, was severely reduced by delayed drilling, especially if it was later than 10 September. However, during the spring and early summer the differences in crop weight due to drilling date declined and in four of the five experiments there were no detectable differences in seed yield between early- and late-sown crops. The yield decline in the fifth trial was small. Measurements of components of yield showed that later-sown crops had fewer pods per plant and slightly smaller seeds but apparently more seeds per pod. The practical significance and reasons for the recovery of late drilled crops from early poorer growth are discussed.

A field study was carried out to determine growth and yield of canola (Brassica napus L.) at different inter row (30, 45, and 60 cm) and intra row (10, 15, and 20 cm) spacing between 1995-97. The closer row Spacing of 30 cm significantly increased leaf area index (LAD, total dry matter (TDM) in both the seasons over wider spacing of 45 and 60 cm. Similarly closer plant spacing of 10 cm also enhanced LA! and TDM over 15 or 20 cm plant spacing. Seed and oil yield was significantly increased in first row spacing compared with 45 or 60 cm row spacing in both seasons. Swd yield was linearly related to TDM yield, harvest index was not changed. The results suggest that closer spacing of 30 cm is optimum for maximizing seed and oil yield for canola under the agro-ecological conditions of Faisalabad.

Four Levels

In agricultural production, one of the limiting factors on plant growth and yield is soil salinity. The plant growth regulators are of considerable importance in alleviating the negative effect of salt stress. The study was carried out to determine the effects of salicylic (SA) and gibberellic acid (GA3) on the growth and some physiological characters in canola (Brassica napus L.) under salinity conditions in greenhouse. For this purpose, a factorial experiment set up as completely randomized design was conducted with three levels of SA (0, 0.5 and 1 mM) and GA3 (0, 50 and 100 mg l-1) and four levels of NaCl (0, 50, 100 and 150 mM) with three replications. In the study, leaf area, plant height, electrolyte leakage, chlorophyll content and the loss of leaf turgor were investigated. Salt treatments reduced significantly all of the considered parameters, compared with the control. Salinity caused a significant reduction of 63 and 67%in plant height and leaf area, respectively, as compared to the control plants. On the contrary, electrolyte leakage was markedly increased (six-fold) with increasing NaCl levels. Gibberellic acid increased significantly plant height and reduced the loss of leaf turgor, without a significant improve in other parameters. The results indicated that application of SA and GA3 to salinity stressed plants did not significantly affect canola vegetative growth. However, GA3 caused a partial decrease in the adverse effect of salinity.

A Cost and return analysis of small scale production of Brassica napus L. varchinensis (Pechay) production using different methods of cultivation was evaluated based on the growth and yield performance of Brassica napus L. varchinensis (Pechay) from field trial. An experiment was undertaken involving four treatments with two methods of planting and two levels of plant density and layed out in Randomized Completely Block Design (RCBD) with replications.  Results showed that the survival rate and growth of Brassica napus L. varchinensis (Pechay) based on the actual number of plants, transplanted plant with high density plants was significantly higher compared to other treatments indicating that transplanted Pechay at high density planting is favorable than other methods. The fresh weight of Pechay after 30 days of cultivation using direct seeding (T1 and T2) was significantly higher compared to T3 and T4.  Partial cost and return analysis in direct seeded Pechay at high planting density were the most profitable while transplanting Pechay seedling at low density planting was the least profitable.
