The Impact

A field experiment was conducted to study the impact of temperature and relative humidity on fruiting behaviour and fruit quality of different mango varieties in Central Plain Zone of Uttar Pradesh during the fruiting year 2017-18 in the Garden of the Department of Horticulture, C.S. Azad University of Agriculture and Technology, Kanpur. The experiment was laid out in Randomized Block Design with 3 replications. Seven varieties of mango were taken for study. Fruiting attributes as influenced by temperature and relative humidity differed significantly in different varieties. Chausa taken highest number of days followed by Amrapali, while Dasheri and Gaurjeet recorded earliest fruit setting. The maximum marble size fruit was noted in Chausa while maximum mature fruit was noted in Local. The maximum fruit drop was recorded under Chausa followed by Dasheri, whereas minimum fruit drop was recorded under Local. Gaurjeet mature first (24th May) followed by Bombay Green (25th May) and Husnara (30th May). Chausa (26th June) and Amrapali (10th July) mature late and very late respectively. The maximum fruit length and width was found in Chausa among all of the varieties followed by Dasheri in length and Husnara in width. The maximum weight of fruit, fruit pulp, stone and peel was recorded in Chausa followed by Husnara (except peel weight), while, the maximum pulp % was recorded in Amrapali. The variety Gaurjeet and Bombey Green both mature first (71 days) followed by Husnara (75 days) while, Amrapali taken longest duration (124 days) followed by Chausa (109 days) and Local (104 days). It has been observed that during fruit setting and fruit development and maturity mango requires less RH as compared to panicle initiation. During growth and maturity RH positively correlated like temperature in all the varieties. It is concluded that mango variety Chausa being maximum in fruit weight, fruit pulp, stone and peel and medium maturing may found suitable for this region.

Aim: To evaluate the efficacy of foliar application of Ascophyllum nodosum extract, homobrassinolide, and triacontanol for improving fruit retention, yield, and quality in mango. Methodology: The experiment was laid out in a randomized block design with 10 treatments, comprising Ascophyllum nodosum extract (1000, 3000, and 5000 ppm), homobrassinolide (0.1, 0.3, and 0.5 ppm), triacontanol (1, 3, and 5 ppm), and water as control. Treatments were foliar sprayed at panicle initiation, pea, and marble stages of fruit growth. Observations were recorded on flowering, fruiting, yield, and fruit quality parameters. Results: All the treatments of Ascophyllum nodosum extract and triacontanol exhibited significant improvement in fruit retention, fruit weight, yield, and fruit quality parameters over control. However, 3000 and 5000 ppm Ascophyllum nodosum extract treatments outperformed all the treatments of triacontanol. Plants sprayed with 5000 ppm Ascophyllum nodosum extract recorded the maximum value for fruit retention (48.15, 36.74, 29.48, and 25.76% at 3, 6, 9, and 12 weeks after pea stage, respectively), number of fruits (133.25 per tree), fruit weight (188.84 g per fruit), and yield (25.16 kg per tree), whereas the lowest values were recorded under control. With respect to fruit quality, 3000 ppm ANE produced the fruits with the highest TSS (19.62 °B), whereas the highest TSS/acid ratio was recorded with 5000 ppm ANE (62.29) treatment. Interpretation: In mango, foliar application of Ascophyllum nodosum extract (3000-5000 ppm) thrice at panicle initiation, pea, and marble stages of fruit growth is effective for reducing fruit drop and enhancing quantum and quality of produce.

ABSTRACT: The present research aimed to evaluate the effect of applying gibberellic acid (GA3) with hand (HP) or natural pollination (NP) on fruit set and the fruit quality of ‘Red’ and ‘Lessard Thai’ sugar apple and ‘Gefner’ atemoya fruits.This study was performed in an experimental orchard located in Homestead, Florida, USA. The experimental design included randomized blocks, with eight treatments, four replicates and four plants per plot. Treatments included: (1) HP; (2) HP + 10 mg L-1 GA3; (3) HP + 100 mg L-1 GA3; (4) HP + 1,000 mg L-1 GA3; (5) NP; (6) NP + 10 mg L-1 GA3; (7) NP + 100 mg L-1 GA3 and (8) NP + 1,000 mg L-1 GA3. The HP plus 1,000 mg L-1 GA3 promoted fruit setting above 90% over the 14 weeks for all genotypes evaluated. Significant increments for length and total fruit weight were observed. ‘Red’ sugar apple and atemoya had a reduced number of seeds per fruit. The NP plus GA3 (1,000 mg L-1) was effective in producing high quality seedless ‘Gefner’ atemoya fruits. This investigationdemonstratedthat GA3 plus hand pollination produced high quality sugar apple and atemoya seeded fruits and in association with natural pollination promoted seedless ‘Gefner’atemoya fruits.

Fertilization outside the season of Siam Orange (Citrus microcarpa L.) with Induction of Flowering and Dormancy Breaking Substances. The Siam orange (Citrus microcarpa L.) produces seasonal fruit with the on-season harvest from July to August while the off-season harvest, i.e. from February to September there is hardly any fruit, or very limited supply. The purpose of this study was to examine the response of flowering induction and dormancy-breaking substances to produce off-season fruits of Siam orange. This research began in April to December 2016. The experiment was arranged factorially with two factors using a randomized block design (RBD), with nine combination treatments and six replications. Flowering induction factors consist of three levels, namely Ik = Control, IP = Paclobutrazol at a dose of 7.5 g/l, and Im = cutting the tip of dormant twigs. Dormancy-breaking substances factor consists of three levels, namely Dk = Control, Db = BAP 200 ppm, and Dn = KNO3 300 ppm. The results of the experiment showed that the highest fruit weight per tree at off-season production was obtained by induction with paklobutrazol (28.86 kg) and the lowest was in control (12.75 kg). Flowering induction treatments was not significantly different effect on fruit quality of Siam orange, represented by weight per fruits, fruit diemater, total soluble solid and vitamine C content was not siginificant different among levels of treatment. Dormancy-breaking substances treatment also not significantly effect on fruit quality of Siam orange. Based on this research it is recommended to induce flower for off-season produce of Siam orange by pruning the tips of dormant twigs or by using paklobutrzol.

The Impact

AbstractBackgroundIntensive agricultural practices have reduced soil health thereby negatively impacting crop yields. There is a need to maintain healthy soils and restore marginal lands to ensure efficient food production. Biochar, a porous carbon-rich material generated from pyrolysis of various feedstock sources is receiving attention as a soil amendment that has the potential to restore soil organic carbon content and also enhance crop yields. However, the physical and chemical properties of biochar are influenced by pyrolysis parameters. These in turn determine its interaction with the soil, thereby influencing its biological properties in terms of impact on soil microcosm and plant productivity. While most studies report the evaluation of one biochar and a single plant cultivar, the role of the plant’s genetic background in responding to biochar as a soil amendment remains unanswered. The impact of six distinct biochars on agronomic performance and fruit quality of three genetically diverse tomato (Solanum lycopersicum) cultivars was evaluated to test the hypotheses that 1) biochars derived from different feedstock sources would produce unique phenotypes in a single cultivar of tomato, and 2) single feedstock-derived BC would produce different phenotypes in each of the three tomato cultivars.ResultsDifferent biochars impacted shoot dry weight, total fruit weight, and yield per plant in each cultivar differently. Both positive and negative effects were observed depending on the biochar-cultivar combination. In ‘Oregon Spring’, Ryegrass straw and CoolTerra biochar enhanced yield. In ‘Heinz’, an increase in fruit weight and citric acid was observed with several of the biochars. In ‘Cobra’, improved yields were accompanied by reduction in fruit quality parameters. Both hypotheses were supported by the data.ConclusionsThis study demonstrated that the genetic background of a plant is an important variable in determining the outcome of using biochar as a soil amendment. Strategies for application of biochar in agricultural production should consider the variables of soil type, feedstock source, pyrolysis parameters and plant genetic background for enhancing crop productivity and carbon sequestration.

Effects of cyperin 10 EC and neem extract on pollinators, fruit setting and fruit quality of mango was investigated. Number of pollinators visited mango inflorescences was higher in morning in comparison to noon and afternoon. In control plants, average 25.67 pollinators visited within 30 minutes which was higher than cyperin 10 EC (20.00) and neem extract treated (24.34) plants. The pollinators were under the order Hymenoptera (26.31%), Diptera (52.42%), Odonata (5.26%) and unidentified (10.53%). Bloomed and fertilized flowers were lower in cyperin treated plants than neem treated and control plants. Highest average fruit weight was obtained from neem treated plants, whereas cyperin treated plants gave lowest percentage of infested fruit and control plants gave highest percentage of deformed fruit.

Various growth regulators have been used to improve the quality of different fruit crops. Foliar spray of macro and micronutrients play an important role in vegetative growth, yield and fruit quality. In the present study, the influence of foliar application of growth regulators and nutrients on fruit splitting and fruit quality was evaluated. For that purpose, Naphthaleneacetic acid (NAA), Potassium nitrate (KNO3) and Boric acid (H3BO3) at the rate of 40 ppm, 1% and 0.3% were used respectively. Spray of chemicals were applied in 2nd and 8th week from full bloom to yield in pomegranate cultivar ‘Golden pearl’. The experiment was designed under Randomized Complete Block Design (RCBD) comprised with seven treatments and replicated thrice. Fruit splitting was reduced (48.68%) significantly with application of KNO3 + Boric acid, while maximum fruit size (60.26 cm2), fruit weight (84gm), fruit grain weight (136.38gm), total soluble solid (TSS) 12.52% and yield (21.9kg/plant) were observed in KNO3 + Boric acid. Moreover, peel weight was increased in control (60.66 gm) and minimum was observed in 48.62 gm in KNO3 + Boric acid. Finally, it is concluded KNO3 %+ Boric acid reveled best results against fruit splitting % and other fruit quality parameters. These findings show that application of KNO3+ Boric acid significantly influences fruit quality of pomegranate when fruit are in the beginning stages of growth and development.

The thinning of flowers and fruit sets did not change the strength of tree growth in a signifi cant way. Szampion cv. trees on rootstock A 2 grew better than on M.7. The trees of Szampion RENO cv. grew significantly worst. The thinning of flowers and fruit sets decreased the yield from a tree and the total yield from 1 ha of the studied biological material. Flower thinning slightly increased the mean commercial yield as compared to the control trees. Thinning of 50% of flowers at the stage of the pink bud and sets after the June fall decreased the number of fruits on the trees of Szampion cv. grafted on M.7. It was only in 2004 that the flower thinning treatment significantly increased the fruit weight. Flower thinning increased the percentage of fruits with a diameter of over 7 cm in the case of Szampion cv. trees grafted on M.7. This treatment considerably (in 2006 significantly) improved fruit colouring. A positive reaction to flower thinning was also observed in Szampion RENO trees. In the case of Szampion cv., which shows a tendency to excessive fruit setting and small fruits, it is better to apply flower thinning eliminating the excess of sets in the period of cell division in growing fruits than do it later, after the June fall. The inflorescence removal treatment requires much more time than thinning of fruit sets.

Objective: To evaluate the effect of pruning on the agronomic variables and fruit quality of habanero peppers (Capsicum chinense Jacq.). Methodology: Habanero peppers were pruned with two intensities, two shoots and three shoots. The control plants were not pruned. The experiment had a randomized block design with four replications. The experimental plots consisted of 50 plants established in rows at a distance of 1.2 m and 0.3 m among plants within a row. The evaluated variables were fruit yield, number of fruits per plant, fruit weight, fruit length and fruit diameter. Data were obtained from 10 harvests. For the analysis, the fruit quality, ash content, moisture, protein and crude fiber were determined.  Results: Plants with two and three shoots produced fruits of 4 and 3.99 cm in length. Plants with two and three shoots produced 42 and 48 % first quality fruits, whereas control plants produced only 10 % first quality fruits. The highest protein content in fruits at physiological ripeness (14 %) and commercial maturity (12 %) was observed in plants pruned to two shoots. Implications: These results show the importance of crop management on the fruit quality of habanero peppers. Further studies are needed to have more information on the effects of crop management on the nutritional content of fruits. Conclusion: The pruning of habanero pepper plants significantly influenced the fruit size, crude fiber and protein content in their fruits

Acid lime (Citrus aurantifolia Swingle) is one of the commercial fruit crops which occupies an important place in the fruit industry, but yield levels of citrus orchards are still very low. An alternate nutrient management system could help in achieving a high yield and quality of acid lime. Thus, an investigation was undertaken on the “Effect of nutrient management on productivity and quality of acid lime (Citrus aurantifolia Swingle)” during 2016 – 2018. The experiment was laid out in randomized block design with twelve treatments, various organic manures, biofertilizers along with inorganic fertilizers including recommended dose of fertilization @ 100%, 75%, 50%, farm yard manure @ 100%, 50%, Vermicompost @ 100%, 50%, Biofertilizers (25 g Azotobacter + 25 g phosphate solubilising bacteria + 150 g vesicular arbuscular mycorrhizal) were applied. The yield and quality characters of acid lime were studied at vegetative and reproductive stages. The observations recorded viz., fruit setting (%), fruit diameter (cm), number of fruits per plant, fruit weight (g), yield per tree (kg) and yield per hectare (tonnes). The results revealed that plants treated with T12 ( 50% RDF+ 75% Vermicompost + Biofertilizers (25 g Azotobacter +25 g PSB +150 g VAM) was observed maximum fruit setting (%), fruit diameter (cm), number of fruits per plant, fruit weight (g), yield per tree (kg), yield per hectare (tonnes). The maximum net income (Rs. 281511.5 / ha) and benefit:cost ratio (4.72: 1) was observed in the treatment T12-50% RDF + 75% FYM + 75% Vermicompost + Biofertilizers (25 g Azotobacter + 25 g PSB + 150 g VAM) which was superior to other treatments.
