Tillage Methods

Field experiments were conducted at the Regional Agricultural Research Station of Bangladesh Agricultural Research Institute, Jessore during rabi (winter) seasons of 1999-2001 to study the tillage and mulching effects on conservation of residual soil moisture, yield attributes and yield of mustard (cv. Daulat.). Three different tillage methods, namely minimum, reduced and conventional tillage were used in the main plots and three different mulch materials, namely rice straw, water hyacinth, black polythene including no mulch were used in the sup-plots. It was observed that reduced tillage and polythene mulch or rice straw mulch conserve more moisture than other tillage methods and mulch application. Tillage practice significantly influenced the dry matter, yield and yield components of mustard. Reduced tillage gave consistently the highest seed yield (969 kg/ha), while minimum tillage gave the lowest seed yield (92 kg/ha). Mulching also resulted in better crop growth and increased yield. Significantly higher seed yield (1164 kg/ha) was recorded from black polythene mulch followed by rice straw mulch (1089 kg/ha). The yield of mustard was obtained due to the interaction effects on reduced tillage and polythene mulch followed by conventional tillage and polythene mulch, which was found superior to all other treatments. Results revealed that polythene mulch or rice straw mulch accompanied by reduced tillage was economically profitable for mustard cultivation/production under rainfed condition. Key Words: Rainfed mustard, tillage, mulching. doi: 10.3329/bjar.v33i4.2303 Bangladesh J. Agril. Res. 33(4) : 597-606, December 2008

The experiment was conducted at Regional Agricultural Research Station (RARS), Jamalpur, Bangladesh during the period of 2017-18 and 2018-19 with the objectives to evaluate the effect of different mulch on soil temperature, soil moisture conservation and yield attributes of chilli. There were five treatments comprising T1: no mulch, T2: rice straw mulch @ 5 t ha-1, T3: water hyacinth mulch @ 5 t ha-1, T4: black polyethylene mulch and T5: white polyethylene mulch. The results revealed that, all the mulch treatment had higher soil temperature and soil moisture content at 5 cm and 10 cm depth compared to no mulch treatment. Soil temperature was highest in black polyethylene mulch, it increased average soil temperature by about 5.7 oC at 5 cm depth and 5.1 oC at 10 cm depth compared to no mulch treatment at 120 Days. Rice straw mulch treatment recorded highest soil moisture, it increased average soil moisture about 27.87 % at 5 cm depth and 28.57% at 10 cm depth over no mulch treatment. Rice straw mulch treatment produced highest green chilli yield (8.81 t ha-1) which was 26.94 % increased over no mulch treatment (6.94 t ha-1).Considering economic analysis, highest gross return (Tk 352400 ha-1), gross margin (Tk 235400 ha-1) and BCR (3.01) was obtained from same treatment T2 i.e., rice straw mulch treatment.

An experiment was carried-out with forty-eight hybrids of pigeonpea and two checks for nine characters at Agricultural Research Station, Tandur (Professor Jayashankar Telangana State Agricultural University). Analysis of variance revealed significant differences among the hybrids for all the nine characters studied. The results of genetic parameters revealed that, high genotypic (GCV) and phenotypic coefficients of variations (PCV) were observed for seed yield and number of pods per plant. Six characters viz., number of branches per plant, number of pods per plant, number of seeds per pod, pod length, test weight and seed yield exhibited high heritability estimates coupled with high genetic advance as per cent of mean which suggested that these traits were amenable for further improvement following simple selection methods. Character association revealed significant positive association of seed yield with plant height,number of branches per plant, number of pods per plant, number of seeds per pod and pod length. Based on divergence studies, the hybrids were grouped into nine clusters in Tocher’s method, cluster II (14 hybrids) was the largest followed by cluster I (13), cluster VI (9), cluster IV (6), cluster IX (4) and the remaining clusters were solitary (III, V, VII and VIII). Out of the nine characters studied, seed yield, days to 50% flowering, test weight and plant height contributed 85.62 per cent of the total divergence and these traits were found to be important factors for genetic differentiation in the hybrids. The overall results of the study revealed that, hybrids under cluster IV and VIII and cluster VII and VIII had maximum and minimum inter cluster distances respectively and possessing high genetic diversity for the characters viz. plant height, number of branches per plant, number of seeds per pod and yield.

A study on comparative productive efficiency and feasibility of lentil varieties both at relay and minimum tillage were conducted at the Regional Agricultural Research Station, BARI, Ishurdi, Pabna, Bangladesh during the Rabi season of 2007-08 and 2008-09. Three lentil varieties viz. BARI Masur-2, BARI Masur-3 and BARI Masur-4 and two sowing methods viz. relay sowing and furrow sowing (Minimum tillage) were compared. The highest seed yield (1.59 t/ha) was obtained from BARI Masur-4 because of highest number of pods/plant and plant population/m2 while lowest from BARI Masur-2 (1.39 t/ha). The sowing methods had significant effect on the seed yield of lentil. Crops sown in furrows produced higher seed yield (1.60 t/ha) than that of crops in relay sowing. The interaction effect between varieties and sowing methods also had significant effect on the seed yield and yield attributes. The lentil variety BARI Masur-4 when grown in furrows gave the highest seed yield (1.70 t/ha). Though seed yield and gross return were highest in furrow sowing but highest benefit cost ratio (4.67) was found in relay sowing method.Bangladesh J. Agril. Res. 40(2): 271-278 June 2015

Sowing Depth

Abstract In South Asia, including Bangladesh, most farmers sow wheat under residual soil moisture after rice is harvested, but the upper layer of soil dries quickly after soil has been prepared for wheat sowing. Crop seeds that are sown either deeply or shallowly can result in failed emergence, low dry matter accumulation, and reduced grain yield. Therefore, appropriate sowing depth is crucial for seedling emergence and successful crop establishment. Considering this, a two-year field experiment was conducted at the research field of the Agricultural Research Station of the Bangladesh Agricultural Research Institute at Dinajpur during the dry, rabi (winter) season of 2013-14 and 2014-15, at four sowing depths, i.e., 2, 4, 6 and 8 cm, to identify the most appropriate sowing depth for higher grain yield. Wheat seeds sown at a depth of 4 cm resulted in significantly highest number of seedlings and seminal roots, tallest plants as well as largest roots and plant biomass followed by sowing at a depth of 6, or 2 cm. Depth of sowing also significantly affected the yield and yield-related attributes, all performing best at a depth of 4 cm. The highest number of spikes m-2, grain yield, straw yield and harvest index were observed when seeds were sown at depths of 4 or 6 cm, relative to 2 or 8 cm. Therefore, a sowing depth of 4 to 6 cm is recommended for wheat cultivation in South Asia, including Northern Bangladesh.

A field experiment on okra taking the variety BARI Dharos-1 with four nitrogen levels (0, 75, 125 and 175 kg/ha) and six levels of green fruit picking (no green fruit picking, first two, first four, first six, first eight and first ten green fruit picking) was conducted at the Agricultural Research Station, Raikhali, Rangamati Hill District to find out the optimum N level and suitable number of green fruit picking during the summer seasons of 2005 and 2006 for the highest economic benefit. The plants were grown for both vegetable and seed production. Growth parameters, green fruit as well as dry fruit characters, seed yield attributes were significantly affected by different levels of N and green fruit picking. Nitrogen levels and green fruit picking increased number of dry fruits per plant, number of seeds per fruit, weight of seeds per fruit and seed yield. Application of N @ 125 kg/ha gave the highest fruit and seed yield of okra followed by 175 kg N/ha. These two N levels also produced maximum 100-seed weight, percentage of germination and seed vigour. The treatment of picking of 10 green fruits produced the highest green fruit yield/ha. But picking of first 4 green fruits produced maximum seed yield, which was statistically at par with those of 2 and 6 green fruits picking. First 4 green fruit picking gave the highest seed vigour whereas first 6 green fruit pickings produced maximum 100-seed weight. Picking of first 4 green fruits accompanied with 175 kg N/ha gave the highest seed yield of 2.86 t/ha, which was closely followed by picking of first 2 or 6 green fruits with 125 kg as well as 175 kg N/ha. Picking of first 2 or 4 green fruits in combination with 125 kg N/ha also gave the similar seed yield. The combination of 125 kg N/ha and first 6 green fruit picking gave the highest gross income (Tk.193.56/ha), net return (Tk.126.35/ha) and maximum BCR of 2.88.

A field experiment was conducted during kharif 2014 - 2015 in the Agricultural Research Station, Adilabad, Telangana to assess the effect of straw mulch and anti – transpirants on growth and yield of soybean. The treatment consisted of A) Anti- transpirants (5) (spray at 15 days after flower initiation): T1 - MgCO3 @ 5% T2 Glycerol @ 5% T3 - KNO3 @ 1% T4 - NaCO3 @ 5% T5 - Control (water spray) B). Straw mulch @ 5 t/ ha after sowing C) Control (no mulch). Among the different anti - transpirants, Na2CO3 @ 5% recorded higher mean seed yield (2862 kg/ ha) which was at par with Glycerol @ 5% (2762 kg/ ha) and MgCO3 @ 5% (2731 kg/ ha). Mulch (straw mulch @ 5 t/ ha) was significantly superior over control (without mulch) with highest mean seed yield (2723 kg/ ha). The combination of straw mulch and anti – transpirant can be recommended as an effective with respect to yield and cost for the soybean under rainfed condition.

A two-year field experiment was conducted at Regional Agricultural Research Station, Jessore during the rabi seasons of 2002-2003 and 2003-2004 to find out the level of disease incidence under different levels of irrigation and fungicide spray on the bulb yield of onion. Four irrigation levels: no irrigation (I1), irrigation at 10 days interval (I2), 20 days interval (I3), and 30 days interval (14) with 4 spray schedules: no spray (F1), one spray at 40 days after transplanting (DAT) (F2), two sprays each at 40 and 55 DAT (F3) and three sprays each at 40, 55, and 70 DAT (F4) were used. Yield and yield attributes varied significantly (p = 0.05) between sprayed and unsprayed, and irrigated and non-irrigated treatments, respectively. Higher yields were obtained with the higher frequencies of irrigation and spray. Application of fungicide reduced the disease severity significantly, while irrigation had no significant effect on disease infection. But there was a decreasing trend of the disease severity with increasing irrigation frequency. The highest bulb yield of onion (12.45 t/ha) was obtained with a total water use of 245 mm in six applications including an effective rainfall of 16 mm and three sprays. The disease severity between sprayed and unsprayed plots ranged from 1.33 to 3.16 for I1, 1.08 to 2.33 for I2 1.16 to 2.83 for I3, and 1.16 to 3.00 for I4, respectively.

Background: Mungbean is a short duration grain legume widely grown in south and Southeast Asia. The extent of variability through Principal Component Analysis (PCA) and cluster analysis in promising mungbean genotypes should be known for possible yield improvement. A study was undertaken to work out the extent of variability among twenty four mungbean genotypes through cluster analysis and Principal Component Analysis (PCA). Methods: The experiment was laid out in a randomized block design with three replications during kharif 2018 and 2019 at the experimental field of Agricultural Research Station, Navgaon (Alwar) under rainfed condition. Result: Principal component analysis revealed that the first three main PCAs amounted 78.80% of the total variation among genotypes for different traits. Out of total principal components, PC1 accounts for maximum variability in the data with respect to succeeding components. Number of branches per plant (28.62%), number of clusters per plant (23.55%) and seed yield (15.58%) showed maximum per cent contribution towards total genetic divergence on pooled basis. Cluster analysis showed that genotypes fall into seven different clusters and their inter and intra cluster distance showed genetic diversity between different genotypes. The maximum number of genotypes i.e., 8 was found in cluster II followed by cluster III comprising of 6 genotypes. Genotypes RMG-1138 and IPM-02-03 representing the mono genotypic cluster signifies that it can be the most diverse variety and it would be the appropriate genotype for hybridization with ones present in other clusters to tailor the agriculturally important traits and ultimately to boost the seed yield in mungbean under rainfed conditions.

Background: Pulses are leguminous crops which not only increase the soil fertility, its fitness and maintain soil health but also essential to meet the nutritional demand of burgeoning human population particularly in developing countries. Mungbean is a major pulse crop of Zone IIa (Transitional Plain of Inland Drainage Zone) of Rajasthan state. Farm profitability can also be enhanced by augmenting farm productivity. Selection of high yielding genotypes may play a vital role to achieve sustainable high agricultural yield at farmer’s field. Therefore, it is prerequisite to identify the suitable genotypes for this zone since the available varieties were not tested for its adaptability. The current study was aimed to evaluate twelve mung bean genotypes for seed yield with four checks in Zone IIa of Rajasthan.Methods: The mung bean crop was raised during Kharif 2018 and 2019 at Agricultural Research Station, Fatehpur- Shekhawati, Sikar (Rajasthan). Seed yield and its ancillary characters have been observed by following standard protocols. Present experiment was conducted in randomized block design with three replications. The material was sown in a four row plot of 4 m length with a spacing of 30 cm between rows and 10 cm between plants.Result: The performance of genotypes RMG 1098, RMG 1132, RMG 1134, RMG 1139 and RMG 1147 were superior to the zonal, state checks and other tested genotypes. The selected high yielding mung bean genotypes can increase farm output per se and farm profitability by sustaining soil health, fitness and productivity of this region.

A pot experiment was carried out in the nethouse of Soil Science Division, Bangladesh Agricultural Research Institute, Joydebpur, Gazipur during 2014-2015 through 2015-2016. The design of the experiment was factorial randomized completely block design with 4 replications. The objectives of the study were to evaluate the potential of Arbuscular mycorrhization (AM) on the germination, yield and yield attributes of lentil treated with different concentration of sodium chloride (NaCl). Five NaCl treatments (0, 1, 2, 3 and 4%) possessed NaCl level as the first factor that were treated with soils before sowing of lentil seeds overriding or pivotal pulse crop in Bangladesh. The second factor consists of mycorrhizal and non-mycorrhizal treatments. Mycorrhizal plants showed better performance in terms of germination %, yield and yield contributing characters than non-mycorrhizal plants. With increasing NaCl concentration germination %, yield and yield contributing characters in the rhizosphere soil, decreased significantly (p<0.01). Interaction effects of mycorrhizal inoculation and NaCl on germination %, growth and yield of lentil were appeared to be statistically non-significant. The highest germination (96.25% in 2014-2015 and 92.50% in 2015-2016), seed yield (6.45 g pot-1 in 2014-2015 and 5.89 g pot-1 in 2015-2016), and stover yield (9.55 g pot-1 in 2014-2015 and 8.58 g pot-1 in 2015-2016) was found in NaCl 0% + AM treatment. The lowest germination %, seed yield and stover yield was found in NaCl 4% treatment. Mycorrhizal inoculation increased seed yield on an average by 31.85% during 2014-2015 and 63.71% during 2015-2016, and increased stover yield on an average by 48.56% during 2014-2015 and 63.55% during 2015-2016 over non-mycorrhizal inoculation. Therefore, it can be concluded that mycorrhizal inoculation increases germination %, growth and yield of lentil over non-mycorrhizal inoculation. The Agriculturists 2017; 15(1) 156-169
