Mango fruit quality plays a significant role in fruit storage. It also directly affects the economic value of fruit in the national and international markets. However, deterioration of soil health due to low organic matter is a major hurdle for mango growers. Scientists suggest incorporation of organic matter. However, high temperature and low precipitation lead to oxidation of organic residues in soil. On the other hand, biochar is gaining the attention of growers due to its resistance against decomposition. It can improve soil physicochemical attributes. Limited literature is available regarding biochar effects on the quality attributes of mango. Therefore, the current study was planned to investigate the effects of acidified biochar on mango quality and yield attributes in alkaline soil. Five levels of biochar, i.e., 0, 5, 10, 20 and 40 Mg/ha, were applied in a randomized complete block design (RCBD). Results showed that 20 and 40 Mg/ha acidified biochar significantly enhanced fruit retention, sugar contents, ash contents and TSS of mango compared to control. A significant increase in mango fruit weight and yield per plant validated the efficacious role of 40 Mg/ha acidified biochar over control. Furthermore, the maximum significant decrease in fruit juice acidity signified the imperative functioning of 40 Mg/ha acidified biochar in alkaline soil. In conclusion, 40 Mg/ha acidified biochar application can improve mango quality and yield attributes in alkaline soil. More investigations on different soil types, climatic zones and mango varieties are recommended to declare 40 Mg/ha acidified biochar as the best treatment for improvement in the quality and yield of mango fruit in alkaline soils.

A field trial was conducted during two consecutive summer seasons of2012 and 2013 at ICAR-Central Potato Research Station, Shillong, Meghalaya to evaluate the integration of nutrient sources on productivity and soil health under rainfed potato cultivation in north eastern hill region of India. There were six treatments of integrated nutrient management viz., 100% Recommended dose of fertilizers,75% RDF through synthetic fertilizers and 25% recommended dose of nitrogen (RDN) through FYM, 50% RDF and 50% RDN through FYM, 25% RDF and 75% RDN through FYM, 100% RDN through FYM and control (no application of any sources of nutrients). The experiment was laid out in randomized block design with four replications. Nutrient management practices showed the significant improvement on growth and yield attributes of potato over control plot. Highest productivity of potato tubers (t/ha) was noticed with application of 75% RDF through synthetic fertilizers along with 25% RDN through FYM. Similarly, the maximum net return was associated with application of 75% RDF and 25% RDN through FYM under investigation. Application of 75% Recommended dose of nutrients through synthetic fertilizers in combination with 25% Recommended dose of nitrogen through FYM was more profitable for sustainable production of potato in the north eastern hill region of India.

A field experiment was conducted at KVK Kalyan instructional farm at Jahajpur of Purulia district of West Bengal during rabi season of 2018-19 to assess the effect of Biochar and Vermicompost as organic soil amendments on yield of brinjal under red and lateritic soils of Purulia, West Bengal. Biochar and vermicompost applied alone additionally in the farmers practice. The experiment design adopted was Randomised Block Design (RBD) having four replications with three treatments The treatments comprises of T1: Application of N:P:K  70:30:30 kg/ha (Farmers’ practice) + FYM @ 2 t/ha, T2: Farmers practice  + Vermicompost @ 5 t/ha, T3: Farmers practice  + Biochar @ 10 t/ha. The growth and yield attributing characters recorded was plant height at 30, 60, 90 and 120 DAT, number of fruits per plant, average fruit weight, yield per plant and total yield. Application of biochar and vermicompost had a significant effect on the growth and yield of Brinjal. Highest growth yield attributes and highest fruit yield (22.36 t/ha) were obtained due to the application of farmers practice + vermicompost @ 5 t/ha (T2). Application of biochar along with farmers’ practice did not show any significant results in brinjal yield as compare to vermicompost application treatment. The potential for long-term benefits of biochar remain to be explored through continued research in the red laterite soils of Purulia district of West Bengal.

Background: Investigations were carried out during Rabi, 2016 and Summer, 2017 at farmer’s field in Kodukkanpalayam village of Cuddalore District, Tamil Nadu to evaluate the direct effects of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), crop residues, farmyard manure with 50% inorganic sources, with and without Rhizobia on various traits of groundnut. There were twelve treatments in randomized block design (RBD) with three replications. Results revealed that the growth and yield components of groundnut viz., plant height, DMP and LAI at flowering stage, number of pods per plant, hundred kernel weight, pod yield and kernel yield were greatly influenced by the treatments. Methods: Combination of Pressmud @ 12.5 t ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T7) recorded the highest and followed by the application of distillery spentwash @ 100 m3 ha-1 + Rhizobia @ 2 kg ha-1 + 50% RDF (T8). Similar trend of results was recorded in summer, 2017 also. This might be due to the increase in the availability of nutrients, which increased the growth and yield attributes of groundnut in both the seasons. Also, use of agro industrial wastes and biofertilizers in any cropping sequence minimize the cost of inorganic fertilizers, thereby act as a boom to farmers by making the waste into wealth and maintain the soil health and fertility. Result: The study revealed the scope of utilization of agro industrial wastes (bagasse ash, pressmud and distillery spentwash), organic sources (crop residues and FYM) and biofertilizer (Rhizobia) in Agriculture.

This study was carried out to determine the effect of vine and fruit pruning on watermelon (Citrullus lanatus) yield. Five pruning methods: P1=no pruning at all, P2=pruning to four vines with two fruits per vine, P3=pruning to four vines with one fruit per vine, P4=pruning to three vines with two fruits per vine and P5=pruning to three vines with one fruit per vine were evaluated on two watermelon cultivars: ‘Sugar baby’ and ‘Julie F1’ under a factorial randomized complete block design with three replications. Investigations were carried out in the seasons 2017A (short rains) and 2017B (long rains) at Karama and Rubona experimental sites belonging to Rwanda Agriculture and Animal Resources Development Board. The obtained results indicated a significant difference among the different cultivars and pruning methods tested during both seasons and at two sites. Generally, all studied parameters recorded higher values during season 2017B than in season 2017A at Rubona site. A similar trend was recorded at Karama site except that the fruit yield per plant and per hectare for plants which were pruned to three vines with one fruit reduced during season 2017B as compared to season 2017A. The highest number of fruits per plant, fruit weight, fruit yield per plant and per hectare was recorded in ‘Julie F1’ compared to ‘Sugar baby’ at both sites and during both seasons. Higher fruit weight was obtained when both cultivars were pruned to three or four vines with one fruit per vine. Higher number of fruits per plant and higher fruit yield per plant was observed under pruning to four vines with two fruits per vine at Rubona site; while at Karama site, higher fruit yield per plant was recorded under pruning to three vines with one fruit or two fruits per vines and pruning to four vines with two fruits per vine. A similar trend was observed in fruit yield per hectare. Based on results of the current study, cultivation of the hybrid ‘Julie F1’ and pruning to three vines with one fruit per vine is recommended for optimum watermelon yield with big-sized fruits.

Soil is the major factor determining saffron yield. Although saffron tolerates different soil types, some soils with specific characteristics perform better than others. This work was conducted to evaluate the performance of saffron crop on different soil types under homogeneous environmental conditions. Four soil types sampled from different regions were tested: Rendzic Leptosols, Anthropic Regosols, Hypercalcaric Fluvisol and Eutric Cambisols. Soil samples were put in large plastic pots (radius=0.27 m, height=0.44 m) and organized in complete block design with four replicates. Combined analysis for four years revealed significant differences between soil types regarding most yield parameters. Saffron corms performed better on calcareous clayey Rendzic Leptosols soil with respect to plant height(PL), flowers per plot, flowers per corm cluster, total stigmas fresh and dry weights, fresh and dry weight of single stigmas and total number of corms. Corms grown on Hypercalcaric Fluvisol soil produced the largest content of Crocin, Picrocrocin and Safranal. A regression analysis was used to evaluate the performance of soil types on the number of flowers per mother corm through four years of the study. In this regard, a positive significant higher slope was obtained for Rendzic Leptosols (y = 4.23x - 8514.3, R²= 0.69, p.0001). Quantitative yield attributes such number of flowers per corm cluster was significantly correlated with organic matter t (r = .60, p=.016) and calcium (r =.52,p.041) contents. Correlation analysis showed that the soil parameters most attributed to the saffron yield were organic matter, phosphorus, potassium and calcium. For soils with limiting factors (Eutric cambisols and anthropic regosols) further studies should focus on improving their performance under saffron crop.

A field experiment was conducted at the Plant Physiology field of Horticulture Research Center, BARI, Gazipur during two consecutive years of kharif 2014 and 2015 to assess the effect of GA3 and NAA on sex expression, yield and yield components of bitter gourd (Momordica charantia L.) var. BARI Karola-1. Eeleven treatments comprising five concentrations each of gibberellic acid (50, 100, 150, 200 and 300 ppm) and naphthalene acidic acid (50, 100, 150, 200 and 300 ppm) along with distilled water considered as control were evaluated in randomized complete block design with three replications. Gibberellic acid (GA3) and Naphthalene acidic acid (NAA) were sprayed at 4 leaf stage; second spray was done at 35-38 DAS and third spray done at flowering stage. All the treatments improved the flowering and yield characters over control. Foliar spray of NAA @ 150 ppm and 200 ppm was found better in terms of sex expression, yield and yield attributes of bitter gourd as compared to control and other treatments. Spray of NAA @ 150 ppm gave the lowest number of male flowers and the highest number of female flowers thereby produced the lowest sex ratio (male:female). Number of fruits/plant, individual fruit weight and fruit yield/plant were also found maximum from NAA 150 ppm. Maximum fruit yield was recorded with the application of NAA @ 150 ppm. Spraying of NAA @ 150 ppm gave the maximum gross return and net return with the highest BCR of 3.17. Bangladesh J. Agril. Res. 44(2): 281-290, June 2019

1. Experiments have been made to determine the effect of treating alkaline soils with manganese sulphate on the quantities of manganese which can be extracted by N-ammonium acetate.2. Two soils of known total and ‘extractable’ manganese content were treated with manganese sulphate solution in the laboratory and re-analysed after definite time intervals. In the first of these, a calcareous soil from the College Farm, the extractable manganese decreased for 14 days after treatment, after which time manganese was again liberated, presumably due to a waterlogging effect. The extractable manganese in the second soil, a slightly alkaline soil with a high organic matter content, increased appreciably after treatment and remained at this level for the duration of the experiment.3. An experiment conducted in the field on a highly calcareous soil showed that the extractable manganese content down to a depth of 12 in., had fallen to its original level only 7 days after treatment. This behaviour is in agreement with the observations of other workers that there is little residual effect from manganese sulphate treatment for subsequent crops. The desirability of performing similar experiments on other soils is suggested.4. The effect of waterlogging and steam sterilization was to increase the quantities of extractable manganese in the soils examined.The authors wish to express their grateful thanks to Mr B. S. Furneaux, M.Sc, for the descriptions of the soils investigated, and to Dr N. H. Pizer for his valuable suggestions in the preparation of this paper. They are also indebted to Mr J. Hargrave of the Agricultural Institute, Kirton, Lines, for providing the Bourne Fen soil, and to Mr J. Tinsley, B.Sc., for pH and organic matter determinations.

Integrated nutrient management (INM) plays an important role to maintain the soil health and improve crop productivity. A field experiment was conducted to study the effect of integrated nitrogen application on transplanted rice. The present investigation was laid out in randomised block design with 10 treatments. Growth parameters like plant height, dry matter accumulation varied significantly among different treatments and the highest value was recorded under the treatment T6 (75% N through fertilizer + 25% N through vermicompost with full dose of P and K). All the yield attributing characters like panicles m-2, grains panicle-1 significantly varied under different treatments. Significantly, higher tiller m-2, grain panicle-1 and panicle length were recorded under T6. Similarly, significantly highest grain yield (4.93 t ha-1) and straw yield (6.01 t ha-1) were observed under T6. Thus, substituting a part of nitrogen fertilizer with organic manure improves soil quality and sustains the crop productivity.

ABSTRACT Humic acid (HA), as a bio-stimulant and a major component of organic matter (OM), can improve plant physiology, soil fertility, and nutrient availability, mainly in low OM soils. Nitrogen (N) is one of the most important nutrients that affect several metabolic and biochemical activities, leading to improved plant development. This study was conducted to investigate the combined effect of HA and N doses on soil organic matter (SOM) and total N concentration, N uptake, corn growth, and grain yield under conventional tillage at Peshawar, Pakistan. Treatments were tested in a randomized block design with four replicates arranged in a factorial scheme 3 × 4 + 1. The respective doses of HA (1.5, 3,0 and 4.5 kg ha-1) were applied at the corn sowing, whereas N doses (80, 120, 160, and 200 kg ha-1) were applied in three splits (1/3 at sowing, 1/3 at the V5 stage, and remaining 1/3 at the tasselling stage) with one control (no HA and N). The application of HA, regardless of the applied doses, had positive effects on SOM, N concentration, N uptake, corn development, and grain yield. However, the application of 4.5 kg ha-1 of HA was the most effective in promoting SOM (0.83%) and total N (0.31%), shoot biomass (10610 kg ha-1), N uptake (1.13%), and grain yield (3780 kg ha-1), even when combined with the N doses of 80, 120 and 160 kg N ha-1. Increasing N doses positively influenced SOM, N concentration, N uptake, and corn growth. The greatest grain yield was obtained at 150 kg ha-1 of N regardless of HA applied doses.

ABSTRACTThis study was conducted during the rainy season of 2017 within the alleys of juvenile oil palms that were 2-year-old at the oil palm plantation located in Ala, Akure-North Local Government, Ondo State. Tomato accessions (NGB 01665 and NG/AA/SEP/09/053) were intercropped at 1, 2 and 3 m from the juvenile oil palm within the alley in a randomized complete block design. The results showed that tomato (NGB 01665 and NG/AA/SEP/09/053) planted at 3 m from the juvenile oil palm performed better than those at other planting distances in terms of growth and yield attributes with number of fruit; fruit weight and yield per hectare of 39.50, 2265.8 g and 3.74 ton/ha respectively. However, the control (sole) recorded the best yield but was not significantly different from those planted at 3 m from the juvenile oil palm. Varietal advantage was recorded by tomato (NGB 01665) with higher number of fruits, fruit weight and yield per hectare (26.94, 1834 g and 3.158 ton/ha) respectively. Intercropping advantage was not recorded for any of the intercropping distance regimes during the trial (when the juvenile oil palms were 2-year-old), with LER values less than unity.
