Bulb Yield

Background: Maharashtra ranks first in onion (Allium cepa L.) production with a share of 28.32%. However, the productivity of onion is low as compared to other countries. In order to enhance onion productivity, new and innovative agri-inputs are being tried continuously like providing humic acid, fulvic acid, plant growth regulators (PGR), auxin/amino acid spray, seaweed extract, biofertilizers, sulphur application etc. PGRs are considered to be one of the novel inputs that can help in increasing the productivity of onion in India economically. Plant growth regulators are considered as a new generation of agrochemicals when added in small amounts, modify the growth of the plants usually by stimulation or modifying one part of natural growth regulatory system, thereby increasing the crop yield. Most of the research data available is based on biochemical, seaweeds etc. Almost negligible literature is available pertaining to a PGR made with formulation of Seaweed extract and Protein Hydrolysate. An attempt has been made in this research work to evaluate the effect of PGR formulated with seaweed extract and Protein Hydrolysate as major constituents on onion bulb yield through both foliar and drenching application. Methods: A field experiment for evaluating the effect of plant growth regulator (PGR) formulated by Research and Development Department, M/s Rashtriya Chemicals and Fertilizers Limited was conducted at Chilli and Vegetable Research Farm, Dr. Panjabrao Deshmukh Krishi Vidyapeeth, Akola (MH). During the experiment, the effect of different concentration of PGR viz., 0.2%, 0.4%, 0.6% and 0.8% and 1.0%, 1.2%, 1.4% and 1.6% through foliar and drenching application, respectively were studied. Result: Statistically, significant results of plant growth regulator application on vegetative growth, yield and qualitative characters of onion crop were observed. Significantly, maximum bulb yield was observed in the treatment PGR @ 0.6% (255.41 kg/ha) through foliar application which is at par with the treatment PGR @ 1.4% (246.67 kg/ha) through soil drenching along with RDF. According to the results, the suitable PGR dose for studied characters of onion under prevailing conditions was 0.6% foliar spray and 1.4% soil drenching along with recommended dose of fertilizers.

An experiment was conducted at the Sher-e-Bangla Agricultural University farm from April to June 2017 in Kharif season to evaluate the performance of two mungbean varieties under different NPK fertilizers doses in field conditions. The experiment was laid out in Randomized Complete Block Design (RCBD), comprising six treatments with three replications. In the experiment, varieties used were BARI mung-6 and BARI mung-5 and the combination of the treatment were T0 = (control), T1 (10-40-25 NPK kg ha-1), T2 (10-60-45 NPK kg ha-1), T3 (20-50-35 NPK kg ha-1), T4 (30-40-25 NPK kg ha-1) and T5 (30-40-45 NPK kg ha-1), respectively. Mungbean cultivars responded noticeably to the supplementary NPK fertilizers as the crop characters were significantly influenced by different levels of NPK fertilizers. Data were recorded on plant height, leaves plant-1, branches plant-1, pods plant-1, seeds pod-1, 1000-seed weight, seed, and straw yield at different days after sowing. Of the two varieties, BARI mung-6 gave the highest seed yield (1.72 t ha-1) next to the higher plant growth and straw yield On the contrary, BARI mung-5 cultivar produced the lowest seed yield (1.57t ha-1), plant growth, and straw yield. The results showed that T3 (20-50-35 NPK kg ha-1) treatment was the best treatment as regards plant growth and yield parameters. The highest seed yield was produced by treated plot T3 (20-50-35 NPK kg ha-1) over the untreated control plot, T1, T2, T4, and T5, respectively. As for the combined effect, V1T3 (BARI mung-6 and T3 = 20kg N + 50kg P + 35kg K ha-1) performed the best results in all growth and development characters. Therefore, the combined application of 20-50-35 kg NPK ha-1 might be considered to be found optimal to get a considerable seed yield of mungbean variety BARI mung-6.

Background: The purpose of this research was to evaluate the growth and bulb yield of shallot (Allium cepa L.) varieties grown by TSS with different population.Methods: This study was carried out in the low dry land at Laleten Village, Malaka District, NTT Province, Indonesia, from March to August 2018. We investigated different plant populations per planting hole using a split-plot design with two factors and four replications. The main plot was the varieties (Trisula and Bima Brebes) and the subplots were the seedling population (100, 200 and 300 plants/m2).Result: There was no interaction between varieties and population for any of the measured parameters. The population only affected the plant height at the beginning of plant growth. A high plant population (300 plants/m2) gave the highest production of single bulbs but was negatively correlated with the bulb weight. Trisula variety produced significantly more single bulbs than the Bima Brebes one. The establishment of the TSS-adapted varieties could be recommended in this area.

The monocropping of rice in the Deltaic zone deteriorates soil health and crop productivity. Seaweeds are marine resources easily available at negligible cost and also rich in bioactive compounds. A field experiment was conducted at Cauvery Delta zone of Tamil Nadu during summer season2021 to evaluate the bio-efficacy of Seaweed extract on growth, yield, and soil properties of rice, Oryza sativa var. ADT53. The experiment was framed in RBD comprising of 12 treatments viz., soil application of Seaweed extract(SWE) @ 12.5kg/ha,25kg/ha, 37.5kg/ha , foliar spraying of SWE gel & liquid @ 0.5% twice at tillering and panicle initiation stages, a combination of soil application and foliar spray and fertilizer alone. Experimental findings revealed that the soil application of SWE  @ 12.5kg/ha along with a foliar spray of seaweed liquid recorded higher plant height (121.1cm),dry matter production (11390kg/ha),yield attributes viz., number of grains per panicle (166), panicle length (21.8 cm), thousand grain weight (14.7g), number of productive tillers per m2 (275), grain yield (5612 kg/ha)and straw yield (7829 kg/ha). However, The soil application of SWE @ 25kg/ha recorded higher soil available nutrients viz.,N(260 kg/ha);P(42kg/ha); K(170kg/ha);Ca(27.7meq/100g); Mg(5.5meq/100g);S(18.2mg/kg);Zn (1.17ppm); Fe (33.82ppm); Cu(1.61ppm);Mn(18.97ppm).The study will help sustain rice productivity and soil fertility in the deltaic zone of Tamil Nadu. The soil application of seaweed extract @ 12.5kg/ha along with foliar spraying (0.5% twice) could be a promising option in the rice ecosystem.

Nigella sativa L. is widely used medicinal plant throughout the world. In Bangladesh it is mainly used as spices in preparing various food items. Sowing time and sowing methods are the influential factors to produce higher seed yield of black cumin. Therefore, this study was undertaken to find out a suitable sowing date and method to produce higher seed yield of black cumin. The two-factor experiment comprised with four sowing dates (1st November, 15th November, 1st December and 15th December) and two sowing methods (line sowing and broadcast seeding). The experiment was carried out following randomized complete block design with three replicates. Results showed that plant growth, yield contributing traits and yield of black cumin significantly influenced by sowing dates and methods. It was observed that the line sowing method compared to broadcast seeding and 1st December sowing among the other sowing dates exhibited higher plant growth with greater production of seed. The combine effect of sowing time and sowing methods showed significantly influenced on black cumin seed production. It was observed that the 1st December sowing with line sowing method increased the seed yield as compared to other sowing dates and methods. From the findings of this study it can be concluded that 1st December following line sowing method would maximize plant growth, yield contributing traits and seed yield of black cumin in Bangladesh.
