Zucchini squash is a popular vegetable linked to many health benefits. Micronutrients although used in a small quantity, play a significant role for optimal plant growth and development however, little is known about foliar feedings of micronutrients on this crop. Therefore, the current research was conducted during 2020 to evaluate foliar micronutrient treatments viz., boron (B), zinc (Zn), silicon (Si), chlorine (Cl), and their combination on growth and yield-related attributes of 'zucchini squash cv. Surma F1'. The 12 micronutrient treatments were untreated control, 0.2% boron, 0.2% ZnSO4, 0.2% SiO2, 0.2% NaCl, 0.2% boron + 0.2% ZnSO4, 0.2% boron + 0.2% SiO2, 0.2% boron + 0.2% NaCl, 0.2% ZnSO4 + 0.2% SiO2, 0.2% ZnSO4 + 0.2% NaCl, 0.2% SiO2 + 0.2% NaCl, and mixture of 0.2% boron + 0.2% ZnSO4 + 0.2% SiO2 + 0.2% NaCl. Eight out of 16 parameters viz., stem length (38.94 cm), stem diameter (3 cm), number of leaves (25.64), length of the largest leaf (30.24 cm), length of plant canopy (133.65 cm), number of marketable fruits (6.54), yield plot-1 (18.76 kg) and total yield ha-1 (46.89 tons) was meaningfully influenced with the foliar spray of the treatments whereas the combination of 0.2% boron and 0.2% ZnSO4 was found to relatively be better regarding growth and yield-related attributes of zucchini squash. The results suggest that foliar spray of micronutrients might play significant role in zucchini production. [ABSTRACT FROM AUTHOR]

Micronutrients are required in small quantities for plant growth and development, nevertheless are indispensable for crop production. Soil application method of fertilizer is very common method for plant nutrition but foliar fertilization also plays effective role under certain circumstances. ZnSO4 applied as a source of Zinc (Zn) and borax utilized as the source boron (B), which are two micronutrients playing significant roles in growth and yield-related attributes of okra (Abelmoschus esculentus L.). Despite of their importance, foliar application of Zn and B on this economically valuable crop received little attention so far. Therefore, to assess the possible response of two okra varieties ('Chamak' denoted here as 'V1' and 'Jadoo' denoted as 'V2') to Zn and B, individual foliar spray of Zn and combination of Zn and B were applied on okra plants. The treatment consisted of T0 (Control), T1 (0.2% Zn), T2 (0.3% Zn), T3 (0.2% Zn + 0.2% B) and T4 (0.2% Zn + 0.3% B). Results showed that foliar application of micronutrients significantly improved the growth and yield-related parameters. Among the varieties, 'Chamak' showed highest plant growth, yield and yield-related attributes over 'Jadoo'. In the case of Zn and Zn-B combination, the highest yield (17.7 tone/ha) was noted from T4 compared to control (11 tone/ha). On the other hand, in terms of combination of varieties and treatments, the highest yield (15.77 tone/ha) was found in V1T4 whereas the lowest (8.35 tone/ha) yield was recorded in V2T0, indicating the good performance of Zn and Zn-B combination for the growth and yield-related attributes of okra.

An analysis of labor resistance to pro-market economic reforms in Bangladesh in the 1980s and 1990s is analyzed as the social support for pro-market reforms has traditionally been on the lower side in developing countries such as Bangladesh. The leftist failure to organize workers and launch a collective movement against pro-market forces apparently promises a better future for market-oriented reforms in Bangladesh.
