Tuberose (Polianthes tuberosa L.) is a perennial summer flower grown by smallholders in Kenya for export. However, its production and export volumes have declined drastically due to nematodes infestation. This study evaluated the effect of Cleome gynandra accessions on nematode management on tuberose. Experiment was conducted at the Horticulture Research Field, Egerton University, Kenya using a randomized complete block design with four replications. The treatments were: five accessions of C. gynandra namely ‘Simlaw’, ‘Egerton’, ‘Taastrup’, ‘PS’ and ‘IP8’, applied at 6 kg/m2 and compared with Brassica napus, solarization and untreated control. Data was collected on growth and yield parameters, nematode infestation and quality of tuberose. Data collected was subjected to analysis of variance at p≤0.05 and means separated using Tukey’s test. Biofumigation with Cleome gynandra accessions helped to reduce nematode population by 34%, gall numbers by 83% and galling index by be 96% when compared with the control. Use of biofumigation helped to improve plant height and leaf number of tuberose by 16% and 87%, respectively, when compared with the control. Use of biofumigation helped to improve spike length by 32%, marketable spikes by 80%, and flower yield by 90% and reduced nonmarketable spikes by 95% when compared with the control. Based on the above results, use of Cleome gynandra accessions and other biofumigants such as rape seed can be used to manage nematodes and improve growth, yield and quality of tuberose.

Crop bio-life is used as a foliar spray to enhance the symbiotic effect between roots and soil micro-organisms enabling the plant to better assimilate nutrients essential for growth. The aim of the study was to assess the effect of crop bio-life on growth, yield and quality of wild okra. The experiment was laid out in a Randomized Complete Block Design (RCBD) with four replications. The experiment consisted of four treatments. The treatments were different crop bio-life concentrations of 0, 25, 50 and 75 ppm.  The highest plant height (103.5 cm) was obtained in plants treated with 25 ppm crop bio-life and the lowest plant height (91.2 cm) was in plants treated with 75 ppm crop bio-life. Plants with the highest chlorophyll content (29.08 µmol per m2) were those treated with 50 ppm crop bio-life while the lowest (18.6 µmol per m2) was 0 ppm treatment.  The highest wild okra yield of 22.3 g leaf wet mass was obtained in plants treated with 25 ppm crop bio-life and the lowest yield (12.9 g) obtained from plants applied with 75 ppm crop bio-life. From the results of this study, it was observed that the plants treated with 25 ppm crop bio-life grew better and had a higher yield, therefore, it is the treatment recommended to farmers.

Abstract A field study was carried out during the spring season of 2017 in the fields of a farmer in the district of Habbaniyah, which is 70 km west of Baghdad, to study the effect of three planting dates (15 March, 1 April and 15 April) on the growth, yield and quality of three cultivars of sorghum (Babel, Warka and Rabeh). The implementation of the experiment was according to a randomized complete block design (R.C.B.D) with split-plot arrangement with three replications. The results of the experiment indicated that the cultivar Rabeh was superior in most of the studied traits such as leaf area (3968 cm2), number of grains per head (2659.00 grains head-1), weight of grains per head (63.41 g) and grain yield (7.44 ton ha-1), while the Babel variety was superior in the percentage of protein (12.21%). As for planting dates, the date of April 1 was superior in most of the studied traits, such as leaf area (3635.33 cm2), number of grains per head (2670.33 grains head-1), weight of grains per head (62.12 g), grain yield (7.55 ton ha-1) and the percentage of protein (11.49%).

There is an immense need to replace chemical fertilizers with biofertilizers to address the soil, environment, and health issues. Endophytic bacteria act as biocontrol agents and promote plant growth and yield. Present study was designed to evaluate the microbial effect of endophytic bacteria on growth, fruit yield and quality of phalsa (Grewia asiatica L.). Three years old healthy, disease and insect-pest free plants were selected for the study. Experiment was laid out in randomized complete block design with four treatments; control, two bacteria such as Burkholderia phytofirmans strain PsJN, Bacillus sp. strain MN54 and their combination (PsJN + MN54) with three replications. The treatments were applied after pruning (January) and flowering (March) as plants need nutrition for both vegetative and reproductive growth. Combined application of PsJN + MN54 resulted in greater vegetative and reproductive growths of plants i.e. number of shoots/plant (29.6), number of leaves/shoot (15.9), number of fruit clusters/shoot (14.0), number of fruits/cluster (14.1), fruit weight (13.7 g) and yield/plant (8.8 kg) than PsJN or MN54 alone and control. Fruit biochemical characteristic i.e. TSS (8.78 °Brix), TA (0.53%), ascorbic acid (44.44 mg 100 mL-1), total sugar (12.29%), reducing sugar (9.59%) and non-reducing sugar (4.92%) contents were also higher in plants treated with PsJN + MN54. All growth, yield and biochemical parameters correlated positively with each other except titratable acidity. Based on performance, the combined treatment (PsJN + MN54) can be applied at two stages, after pruning and at flowering, for better growth, yield and quality of phalsa crop.

Different crops have variations in their responses to applied micronutrients in soil. A study was conducted on floodplain soil of Bangladesh to explore the response of potato to application of micronutrients in soil. The experimental site was located at farmers’ field in Chandina upazila under Cumilla district of Bangladesh covering the soils of Old Meghna Estuarine Floodplain (AEZ 19) during 2011-12. Randomized complete block design with 3 replications of each treatment was used in the experiment, where seven treatments including a control were tested. Additive element trial technique was followed while designing the treatments taking six micronutrients i. e. Zn, B, Cu, Mn, Fe and Mo at the rate of 3, 2, 2, 3, 5 and 1 kg ha-1, respectively. Macronutrients, such as N, P, K and S were applied at recommended rates to all plots. The highest tuber yield (28.7 t ha-1) was produced by the combined application of Zn and B. Only Zn application was sufficient to obtain the highest content of protein as well as content of almost all the nutrients in potato tuber. Antagonistic relation between Zn and P in soil-plant system was recorded in the study. Zinc and boron application influenced different growth and yield parameters of potato while the other four added micronutrients did not have any significant effect but combined application of Zn, B, Cu, Mn, Fe and Mo had beneficial role for better plant growth and production. Proper management of zinc and boron fertilizers including optimization of application rates of those nutrients can help to uphold the yield and quality of potato in floodplain soil. SAARC J.

Growing Conditions

Brinjal is a crop grown widely all over India and preferred by both rich and poor. The Chhotanagpur plateau of Jharkhand is famous for quality vegetable production and brinjal is very commonly grown in this region almost throughout the year. However, the most of the commercial growers using plant protection chemicals and synthetic fertilizers those are so expensive that poor farmers can’t afford. The extensive uses of agro-chemicals and synthetic fertilizers also reduce the quality of both the produce and the cultivated soil. In this context, an attempt has been made through the present investigation by growing different varieties of brinjal by adopting Vedic (Enriched Sanjeevani) Farming and Homa Induction (Agnihotra) techniques with their respective four non-chemical alternative growing approaches, viz.  E1C1: Enriched Sanjeevani (1%), E1C2: Absolute Control (inherent fertility status of the experimental plot); E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra). Five varieties of the crop, viz. V1: Swarna Pratibha; V2: Swarna Neelima; V3: Swarna Shakti; V4: Mukta Jhuri; V5: Long Green were grown with their four replications under four growing conditions and the Randomized Completed Block Design was adopted for field trials. Different growth, yield and quality attributing characters of the crop were taken into account and findings revealed that E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) was the most suitable growing condition for V2 (Swarna Neelima) with the maximum yield (72.37 t ha-1). Different growth and yield attributes of the crop varieties (especially in the case of V2: Swarna Neelima) were highly influenced by Enriched Sanjeevani (1%) + Homa Induction (Agnihotra) [E2C1] growing condition resulting higher benefit cost ratio of 6.78. Quality contributing attributes were also highly influenced by homa induction (Agnihotra), as a consequence, higher level of dry matter, TSS, and ascorbic acid contents were estimated from almost all samples collected from E2C1: Enriched Sanjeevani (1%) + Homa Induction (Agnihotra), and E2C2: Only Homa Induction (Agnihotra) growing conditions.

Economic use of organic and inorganic fertilizers following their availability is necessary for livestock-based Nepalese farming systems. However, how best to integrate these fertilizers in an appropriate manner is not yet clear. Thus, this study was conducted in the horticulture farm of the Agriculture and Forestry University (AFU), Rampur, Chitwan, Nepal from November 2018 to February 2019 to evaluate the effect of organic and inorganic sources of nitrogen (N) on growth, yield, and quality of beetroot (Beta vulgaris L.) varieties. The experiment was laid out in a two factorial randomized complete block design with four replications consisting of two beetroot varieties, i.e., Madhur and Ruby Red, and five N source combinations, i.e., N1: 100% poultry manure (PM), N2: 50% PM + 50% urea, N3: 100% farmyard manure (FYM), N4: 50% FYM + 50% urea, and N5: 100% urea (120:80:40 kg NPK ha−1). Results of this study indicated a significant impact of N sources and varieties on the assessed parameters. During harvest, a significantly higher plant height (41.84 cm), number of leaves per plant (14.68), leaf length (34.56 cm), leaf width (11.38 cm), and beetroot diameter (72.15 mm) were observed in the N2 treatment. Likewise, higher economic (49.78 t ha−1) and biological yields (78.69 t ha−1) were also recorded in the N2 compared to other N sources. Out of the two varieties, the Madhur variety was significantly better in most growth and yield parameters. Similarly, the Madhur variety showed a significantly higher economic (44.49 t ha−1) and biological yields (69.79 t ha−1) compared to the Ruby Red variety. However, the physiological weight loss was higher in the Ruby Red variety. Therefore, the current study suggests that an integration of poultry manure along with the combination of N fertilizer and the Madhur variety is the best combination for quality beetroot production in the Terai region of Nepal.

This study was conducted to examine growth, yield and quality performances of five turmeric genotypes. The experiment was laid out in randomized complete block design with three replications. Results showed that different genotypes significantly influenced on plant growth, yield and quality of turmeric. The highest germination (97 %), number of leaves (8.16), plant height (69.51 cm), weight of rhizome (47.06 g/plant) and yield (6.01 t/ha) was found from “Sinduri Holud” (BARI Holud-2). But this genotype scored the lowest percentage in curcumin (0.30 %) and low dry matter (22.54 %). While local genotype (“Mota Holud”) performed the lowest germination (87.57 %) and minimum plant height (53.52 cm), leaf area (127.42 cm2), number of fingers per rhizome (3.73), weight of rhizome (34.16 g/plant) and yield (4.78 t/ha). But this genotype contained the highest curcumin (2.10 %), and “Mala Holud” attained maximum dry matter (25.20%). Based on flesh color, dry matter and curcumin contents local turmeric genotypes performed superior than that of the check varieties. From the findings of this investigation, it can be concluded that local genotypes can be used in breeding program for development of high quality turmeric in Bangladesh.

Squash seeds yield and quality can be improved by proper population plant spacing and the pollen quantity, which influences the pollination quality and fertilization. Nine experiments were conducted as a factorial combination of three spacing between plants (0.8 x 0.3, 0.8 x 0.6 and 0.8 x 0.9 m), two quantities of pollen (50% of an anther and another entire one) and natural insect pollination. Seed and fruit production parameters, and seed quality were evaluated. A randomized complete block design, five replications, with ten plants per plot was adopted. Larger plant spacing increased the average number of mature fruits and seed yield per plant. Seed yield was directly proportional to the amount of pollen used during pollination. Higher amounts of pollen resulted in higher seed yield per area, but the plant spacing did not affect this characteristic. Manual pollination, using a whole anther, did not differ from natural pollination in relation to seed yield and quality.

An experiment was conducted at the research field of the Department of Agricultural Botany, Patuakhali Science and Technology University, Patuakhali under the Agro-ecological zone-13 (AEZ-13) during the period from November 2012 to February 2013. The aim of the study was to identify the most effective irrigation level for obtaining the better growth and higher yield performance of BARI Gom-25 that are suitable to cultivate under  coastal region of Patuakhali, Bangladesh. So, the present study was consists of five irrigations levels including control viz. control or no irrigation (T0), one irrigation at 25 DAS (T1), two irrigations at 25 and 40 DAS (T2), three irrigations at 25, 40 and 55 DAS (T3)  and four irrigations at 25, 40, 55 and 70 DAS (T4). The seeds of BARI Gom-25 were collected from the BARI, Joydebpur, Gazipur on 22 November, 2012. The experiment was laid out in completely randomized block design (RCBD) with four replications and analysis was done by the MSTAT-C package program where means were separated by DMRT at 5% level of probability. Data were recorded on various growth and yield attributing traits. The plot size was 5 m2 (2.5 × 2.0 m) where row to row and seed to seed distances were 20 and 10 cm respectively. Data were collected on various morpho-physiological growth, yield and yield attributing traits. Results obtained from the present study, whole characters of the study were significant at 5% by the moisture (irrigation) levels where three irrigations given at 25, 40 and 55 DAS had most effective than that of other moisture levels and no irrigation. From the results investigation, it was found that the tallest plant (76.86 cm), maximum requiring days to anthesis (61.00 days), maturity (109.0 days) and maximum number of effective tillers (5.00 hill-1),the highest grain growth (3.11g at 36 DAA) and grains (44.00 spike-1) were obtained with three irrigation (T3) levels. Similarly, T3 further showed the greater performance on spike length (17.28 cm), 1000-seed weight (50.16 g), grain (4.16 t ha-1), straw (5.89 t ha-1) and biological yield (10.05 t ha-1) as well as the higher harvest index (41.39%). Investigated above whole characters were produced lower performances under no moisture (irrigation) treatments. These results indicated that irrigation at three times (T3) would be most advantageous irrigation levels for wheat production under the studied non saline ecosystem of coastal region.Progressive Agriculture 29 (2): 99-106, 2018
