The global demand for pomegranate is increasing consistently since this fruit has recently been merited with the status of a ‘super fruit’; apart from its other culinary and medicinal (both ethnomedical and modern) uses. Thus, researchers from different parts of the world have been trying to standardise agro-technical, in vitro-biotechnological and molecular-marker-assisted technologies for enhanced production, superior plant protection, post-harvest management, and genetic improvement of pomegranate, grown in various agro-climatic zones. Upon realising this context, the present review was framed after an extensive groundwork, carried out on 250 published scientific articles, reports, bulletins, and web pages extracted from various scientific (CeRA, Google Scholar, JGate, PubMed, Scopus, and Web of Science) and public (Google and Bing) domains, in order to summarise most of the recent advancements in botanical, ethno-medicinal uses, agro-technological advancements, post-harvest management and molecular characterisation of pomegranate. This review further includes surveys on multiple technologies, along with their achievements and demerits that need immediate attention of the pomegranate researchers for sustainable improvement of this fruit crop, with immense medicinal value.

Insects and other animal pollinators are vital for the production of healthy crops for food, fibers, edible oils, medicines, and other products. It is estimated that more than 1,300 types of plants are cultivated around the world for food, beverages, medicines, condiments, spices and even fabric. Out of these, almost 75% are pollinated by animals. In fact, pollinators such as bees, birds and bats affect 35 percent of the world’s crop production which increased outputs of 87 of the leading food crops worldwide and obviously within these, fruits and vegetables are the most benefited items. With highest efficacy of honeybees, approximately 100,000 different species of animals around the world act as pollinators to 250,000 plant species on the planet. But now the population of wild, native and managed pollinators is declining at an alarming rate owing to alterations in their food an...

Pooled analyses of two year experimental data are subjected to multivariate analysis (Principle Component Analysis) and biplot analysis to identify the principal yield attributes. Considerable variations were observed in yield attributing and leaf nutrient status of guava plant upon micronutrient fertilization (B, Zn and Cu). The highest fruit yield was obtained with combined foliar application of B and Zn. From Principle Component Analysis it was observed that leaf B followed by leaf Zn content has most significant role in regulating principal yield attributing traits and fruit yield of guava. From Biplot-analysis it was also clearly revealed that combined application of B and Zn were the most effective in improving yield attributing traits and ultimately the yield of guava.

Intensive horticultural systems are often based on optimising the productivity of monocultures. In those systems, crop diversity is reduced to one or very few species that are generally genetically homogeneous, the planting layout is uniform and symmetrical, external inputs are often supplied in large quantities and such systems are widely criticised today for their negative environmental impacts. Conversely, multispecies cropping systems in the same piece of land in a right sequence by optimally maintaining the space and time may often be considered as a practical application of ecological principles based on biodiversity, plant interactions and other natural regulation mechanisms thereby proves their superiority in all-round benefit of farmer as well as the environment. Methods for designing multispecies systems barel...

A field experiment was carried out on alluvial soil at West Bengal during the winter season of 2014-15 and 2015-16. The experiment comprised of five treatments [T , Recommended dose of fertilizer (RDF) of NPK; T , RDF of NPK + 2.0 kg soil applied B/ha; T , RDF of NPK + 0.1% boric acid spray at 40 days after planting (DAP); T , RDF of NPK + 0.1% boric acid spray at 40 and 60 DAP; and T , RDF of NPK + 0.1% boric acid spray at 40, 50 and 60 DAP] arranged in a completely randomized block design replicated four times. Plant growth, yield, nutrient concentration and quality parameters of potato tuber (specific gravity, total soluble solids, tuber hardness, total acidity, Vitamin C and protein) were analyzed in the experiment. Experimental findings showed that RDF of NPK + 0.1% boric acid spray (thrice) produced significantly higher number (3.70 × 10 ha) and yield (33.49 t ha) of processing grade tuber than other boron levels (foliar and soil) tested. Application of RDF of NPK + 0.1% boric acid spray (thrice) exhibited its superiority by producing tubers with significantly higher specific gravity, total soluble solids, tuber hardness, total acidity, Vitamin C, protein and starch content with lowest phenol content and lighter chip colour. The results of this study indicate that application of boron (0.1% boric acid at 40, 50 and 60 DAP) in combination with RDF (200 kg N, 150 K O and 150 kg P O ha) is required for optimum yield of processing grade p o t a t o (c v. K u f r i Chipsona-3) in alluvial Gangetic plains of West Bengal.

The treated seeds were raised on polythene bags under shade net house (covered with 200-micron thickness polythene shade net) condition to avoid climatic irregularities. The experiment was laid out in a completely randomized design comprising eight treatments (GA 3 50 ppm and 100 ppm, KNO 3 50 ppm and 100 ppm, Thiourea 50 ppm and 100 ppm, water soaking, and directly sown seed i.e. control) and replicated for five times. The result of the present investigation revealed that amongst the different concentrations of used chemicals, GA 3 100 ppm was most efficient to ensure the maximum germination percentage (81.67%) which was 96.01% higher than the control. Similar trend of obtaining highest values from GA 3 treated seed on most of the seedling growth parameters was also observed such as highest seedling height (442.23 mm), shoot (2.51 mm) and root diameter (3.22 mm), leaf number (12.00), seedling fresh (2.14 g) and dry weight (1.01 g), leaf chlorophyll content [chlorophyll a (78.51 mg g-1 FW), chlorophyll b (98.70 mg g-1 FW) and total chlorophyll (135.70 mg g-1 FW), respectively] and leaf nitrogen (3.40%) and potassium content (3.42%).

The results revealed that the maximum canopy volume (81.26 m3) of Nagpur mandarin was recorded when the concerned scion was budded on Karna khatta. The maximum number of fruits per plant (238.33) and yield (37.52 kg tree−1) were recorded when Rough lemon was used as rootstock. Fruits with lowest acidity were produced when Nagpur mandarin was budded on Karna khatta rootstock. However, the fruits exhibiting maximum values for other quality parameters like total soluble sugar, total sugar, and ascorbic acid were obtained in Kumquat rootstock. The highest leaf N and K contents of Nagpur mandarin were recorded in Karna khatta rootstock, whereas, both the Kumquat and Acid Lime rootstock revealed superiority in leaf P acquisition over the others. Unweighted pair group method with arithmetic mean (UPGMA) clustering analysis revealed that Lemon, Gandharaj and Rough lemon rootstocks, displaying a close association with each other, exhibited an overall comparable horticultural performance and yield. From other cluster analysis, the Kumquat rootstock was recognized for its uniqueness and superior biochemical quality attributes, and was found to be separated from other rootstock clusters. Hence, the results of this study hold the potential to meet the consumers’ demand, by selecting the suitable region- and agro-climate-specific rootstalk, that was unavailable so far.

A field experiment was carried out on alluvial soil at West Bengal during the winter season of 2014-15 and 2015-16. The experiment comprised of five treatments [T , Recommended dose of fertilizer (RDF) of NPK; T , RDF of NPK + 2.0 kg soil applied B/ha; T , RDF of NPK + 0.1% boric acid spray at 40 days after planting (DAP); T , RDF of NPK + 0.1% boric acid spray at 40 and 60 DAP; and T , RDF of NPK + 0.1% boric acid spray at 40, 50 and 60 DAP] arranged in a completely randomized block design replicated four times. Plant growth, yield, nutrient concentration and quality parameters of potato tuber (specific gravity, total soluble solids, tuber hardness, total acidity, Vitamin C and protein) were analyzed in the experiment. Experimental findings showed that RDF of NPK + 0.1% boric acid spray (thrice) produced significantly higher number (3.70 × 10 ha) and yield (33.49 t ha) of processing grade tuber than other boron levels (foliar and soil) tested. Application of RDF of NPK + 0.1% boric acid spray (thrice) exhibited its superiority by producing tubers with significantly higher specific gravity, total soluble solids, tuber hardness, total acidity, Vitamin C, protein and starch content with lowest phenol content and lighter chip colour. The results of this study indicate that application of boron (0.1% boric acid at 40, 50 and 60 DAP) in combination with RDF (200 kg N, 150 K O and 150 kg P O ha) is required for optimum yield of processing grade p o t a t o (c v.

Keeping these facts in foreground, replicated field experiment was conducted during 2013-14 and 2014-15 at HRS, Mondouri, BCKV, West Bengal with eleven treatments consist two different levels of NAA, GA3, 2,4-D, ZnSO4 and H3BO3 along with a control (water spray). Results of investigation revealed that application of 2,4-D @ 10 mg/l recorded highest fruit set (48.80%). Maximum fruit retention (42.83%) and total no. of fruits/tree (514) were obtained with the application of NAA @ 20 mg/l. Application of GA3 @ 20 mg/l recorded significantly (p≤0.05) higher yield (30.67 kg/tree), fruit weight (60.5 g), fruit length (5.8 cm), fruit breadth (5.1 cm), pulp to seed ratio (13.9) and specific gravity (1.104) as well as economic returns over control...

The treated seeds were raised on polythene bags under shade net house (covered with 200-micron thickness polythene shade net) condition to avoid climatic irregularities. The experiment was laid out in a completely randomized design comprising eight treatments (GA 3 50 ppm and 100 ppm, KNO 3 50 ppm and 100 ppm, Thiourea 50 ppm and 100 ppm, water soaking, and directly sown seed i.e. control) and replicated for five times. The result of the present investigation revealed that amongst the different concentrations of used chemicals, GA 3 100 ppm was most efficient to ensure the maximum germination percentage (81.67%) which was 96.01% higher than the control. Similar trend of obtaining highest values from GA 3 treated seed on most of the seedling growth parameters was also observed such as highest seedling height (442.23 mm), shoot (2.51 mm) and root diameter (3.22 mm), leaf number (12.00), seedling fresh (2.14 g) and dry weight (1.01 g), leaf chlorophyll content [chlorophyll a (78.51 mg g-1 FW), chlorophyll b (98.70 mg g-1 FW) and total chlorophyll (135.70 mg g-1 FW), respectively] and leaf nitrogen (3.40%) and potassium content (3.42%).

The results revealed that the maximum canopy volume (81.26 m3) of Nagpur mandarin was recorded when the concerned scion was budded on Karna khatta. The maximum number of fruits per plant (238.33) and yield (37.52 kg tree−1) were recorded when Rough lemon was used as rootstock. Fruits with lowest acidity were produced when Nagpur mandarin was budded on Karna khatta rootstock. However, the fruits exhibiting maximum values for other quality parameters like total soluble sugar, total sugar, and ascorbic acid were obtained in Kumquat rootstock. The highest leaf N and K contents of Nagpur mandarin were recorded in Karna khatta rootstock, whereas, both the Kumquat and Acid Lime rootstock revealed superiority in leaf P acquisition over the others. Unweighted pair group method with arithmetic mean (UPGMA) clustering analysis revealed that Lemon, Gandharaj and Rough lemon rootstocks, displaying a close association with each other, exhibited an overall comparable horticultural performance and yield. From other cluster analysis, the Kumquat rootstock was recognized for its uniqueness and superior biochemical quality attributes, and was found to be separated from other rootstock clusters. Hence, the results of this study hold the potential to meet the consumers’ demand, by selecting the suitable region- and agro-climate-specific rootstalk, that was unavailable so far.
