Abstract: The experiment was carried out in the field of Horticulture Research Centre (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur to evaluate the effect of foliar application of boron (B) and zinc (Zn) on growth, yield attributes, quality and seed yield of okra. The experiment was planned with 16 treatment combinations comprising four levels each of B (0, 0.1, 0.2 and 0.3% borax, respectively) and Zn (0, 0.1, 0.2 and 0.3% zinc sulphate, respectively) along with the blanket dose of fertilizers of N, P, K, S and cow dung at 120, 40, 80, 20 and 10000 kg ha-1, respectively were used in all treatments. The two factor experiment was laid out in the randomized complete block design with three replications. Results revealed that the foliar application of boron and zinc either single or in combination had significant effect on yield, yield attributes and quality of okra seed. Most of the yield attributes of okra were significantly increased by the combined foliar application of borax and zinc sulphate up to 0.2% borax and 0.2% zinc sulphate. The highest seed yield (2.52 t ha-1) was obtained from the treatment combination of 0.2% borax and 0.2% zinc sulphate followed by the treatment combination of 0.2% borax and 0.3% zinc sulphate. The highest oil content (16%) in seed was also produced from the same treatment (0.2% borax and 0.2% zinc sulphate). The improved protein content (17.75%) was found in combination of 0.1% borax and 0.3% zinc sulphate. The combined foliar applications of zinc and boron fertilizers were detected superior to their single application. The results suggest that the combination of 0.2% borax and 0.2% zinc sulphate could be used as foliar for seed yield maximization of okra. Hence, the foliar fertilization rates of zinc sulphate should be increased for okra production.

Abstract: Zinc (Zn) fertilization is reflected a significant agronomic strategy for global food security. Deficiency of zinc in soils could be caused to decrease the crop yield. Hence an experiment was made over two years at the research farm of Pulses Research Sub-Station of Bangladesh Agricultural Research Institute (BARI), Gazipur and in the research farm of Regional Agricultural Research Station (RARS), Ishwardi and Jessore, during Rabi season to assess the sensitivity of different varieties of lentil to Zn fertilization and evaluate the Zn in terms of yield and Zn mineral content in seed. There were 12 treatment combinations comprising six lentil varieties (V1 = BARI Masur-2, V2 = BARI Masur-3, V3 = BARI Masur-4, V4 = BARI Masur-5, V5 = BARI Masur-6 and V6 = BARI Masur-7) and two levels of zinc (0 and 2 kg ha-1). The experiment was laid out in split-plot design with three replications. Results reveal that growth, yield attributes and yield varied positively by zinc level and variety. Among the varieties, BARI Masur-7 followed by BARI Masur-6 gave the highest seed yield. Interaction of variety and zinc the highest mean seed yield (1568 kg ha-1 at Gazipur, 2396 kg ha-1 at Ishurdy and 1639 kg ha-1 at Jashore) produced by the treatment V6Zn2. The improved protein content (28.5% at Gazipur, 28.9% at Ishurdy and 29% at Jashore) and zinc content (70.2 ppm at Gazipur, 73.6 ppm at Ishurdy and 69.9 ppm at Jashore) was achieved in V6Zn2 treatment. The result, suggest that 2 kg Zn ha-1 could be applied in any lentil variety for quality improvement and yield maximization in terrace and calcareous soils of Bangladesh. The current study recommended conducting another experiment for further monitoring and determining the appropriate Zn dose for lentil production through application of different zinc rates in Zn- deficient soils.

Abstract: Field and laboratory studied were conducted at the research field of Olericulture Division and laboratory of Postharvest Technology Section under the Horticulture Research Center (HRC), Bangladesh Agricultural Research Institute (BARI), Gazipur to find out the suitable sweet pepper hybrid (P7×P8) and to determine the appropriate storage temperature and storage material on shelf life and fruit quality of hybrid sweet pepper. The laboratory result reveal that perforated poly bag was found better in reducing fungal decay (6.02%) as well as for better visual appearance and excellent nutritive quality during 10th day of storage irrespective of temperature. The minimum weight loss of fruits was (0.86%) noted at temperature of 4°C kept in perforated poly bags at 10th day of storage. Higher TSS value (5.49% in 10th day and 5.58% in 20th day of storage) was attained under ambient temperature with perforated package. Maximum beta carotene value in fruit (42.78 µg per 100 g) was observed during 10 days storing at perforated poly bag of 4°C temperatures. However, freshness of fruits was up to the marks and senescence of fruits was delayed in 4°C and in perforated poly bag up to 10th day of storage. These temperature (4°C) and perforated poly bag might be afforded a beneficial balance to visual appearance and nutritional status. The results suggest that fruits of sweet pepper at 4°C stored in perforated poly bag for a period of 10th day might be appropriate regarding the firmness, good visual appearance and fruit quality.

Abstract: Potassium (K) is considered as key element for plant growth and physiology and improvement of productivity and quality of crops. The potassium (K) reduction from agricultural soils of Indo-Gangetic plain had been observed due to rapidly increasing intensive cropping systems, in combination with imbalanced fertilization. Now, burning issue is needed to better understand the role and dynamic of K in plants and K-use efficiency of crops. Hence, this study was undertaken during two consecutive years of 2015-16 and 2016-17 to know the effects of different levels of potassium on lentil productivity, nodulation, nutrient uptake and K use efficiency. The experiment was laid out in randomized complete block design considering five treatments with thrice replicates. The treatments were T1 (K Control), T2 (15 kg K ha-1), T3 (30 kg K ha-1), T4 (45 kg K ha-1) and T5 (60 kg K ha-1) along with the blanket dose of N18P20S10Zn2B1.5 kg ha-1 and cowdung 3 t ha-1. Yield and yield attributes of lentil responded significantly to K fertilizer. The highest mean seed yield (1684 kg ha-1) and maximum seed yield increase over control (31.9%) got from T5 treatment followed by T4 treatment. The highest total nutrient (N, P, K, S, Zn and B) uptake, maximum nodulation and the highest protein content (29.4%) in seed was, however, recorded from the plot receiving of 60 kg K ha-1. Apparent K recovery efficiency was recorded higher (17.8%) from T4 treatment. Apparent K recovery efficiency followed the order: T4>T5>T3>T2. From the economic point of view, T5 followed by T4 treatment is viable and sound. The results of the experiment suggest that 60 kg K ha-1 might be applied along with N18P20S10Zn2B1.5 kg ha-1 for lentil cultivation in calcareous soils of Bangladesh. The K rates for fertilizer recommendation in lentil need to be revised to take account for highest yield by higher increasing rate of K in soil.
