ThesisItem Open Access STUDIES ON THE EFFECT OF BORON, UREA AND GA3 ON GROWTH, YIELD AND QUALITY OF BROCCOLI (Brassica oleracea var. italica)(Birsa Agricultural University, Ranchi, Jharkhand-6, 2017) Verma, Sudha; Jha, K.K.Sprouting broccoli (Brasica oleracea var. Italica) is one of the most nutritious cole crop. Although broccoli is not so popular yet in Jharkhand, it is slowly gaining popularity during the last few years among the consumers. It is gaining importance due to its nutritional value including flavour, taste, carotenoids and anticancerous properties. Among the entire cole family, broccoli is rated as most remunerative. It has tremendous production capability and its production and productivity can be increased further by applying foliar spray of plant nutrient and GA3. The role of mineral nutrients and plant growth regulators in various physiological and biochemical processes in plant to regulate growth and yield is established. Beside this, the beneficial effect of applying foliar plant nutrients and plant growth regulators, expressed as an increase in yield and improvement of crop quality has been noted in many vegetables species. The present investigation entitled, “Studies on the Effect of Boron, Urea and GA3 on Growth, Yield and Quality of Broccoli (Brassica oleracea var italica)”, on cv. Fiesta was carried out during winter seasons in the consecutive years 2013-14 and 2014-15 at Vegetable section of Horticulture garden under faculty of Agriculture, Birsa Agricultural University, Ranchi, (Jharkhand). The experiment consisted of 16 treatments replicated thrice was laid out in Randomized block design. The foliar nutrients and plant growth regulators used were Boron, Urea and GA3 at different concentrations, individually as well as in different combinations. The spraying was done twice at 20 and 40 days after transplanting. During the course of investigation, it was observed that nutrients and plant growth regulators showed remarkable influence in vegetative growth, curd initiation, curd production, yield, quality and Shelf life. Thus on the basis of experimental findings it may be safely concluded that broccoli cultivar Fiesta when treated with urea @ 1.0% with GA3 @ 50ppm spray resulted higher yield and profit per hectare. However the urea @ 1.5% along with GA3 @ 75ppm in combination, had shown the impressive vegetative growth. In case of earliness in curd maturity, the urea @ 0.5% in combination with GA3 @ 75ppm plus B as Borax @ (2%) had shown the most favourable effect. Among various quality parameters, the treatment T15 having the combination of Urea @ 0.5% + GA3 @ 75ppm + B as Borax @ 2% had shown quite impressive results. However, the spray of GA3 @ 75ppm has favourable effect in enhancing the Shelf Life of curd at ambient condition.ThesisItem Open Access RESPONSE OF CHEMICALS ON FLOWERING FRUITING AND QUALITY OF MANGO (Mangifera indica L.) CV. MALLIKA UNDER HIGH DENSITY ORCHARDING(Birsa Agricultural University, Ranchi, Jharkhand-6, 2017) Saha, Devendra Prasad; Jha, K. K.In the present study, entitled “Response of Chemicals on Flowering, Fruiting and Quality of Mango (Mangifera indica L.) cv. Mallika Under High Density Orcharding” an attempts has been made to enhance the flowering, fruiting, yield and quality attributing characters and prolonged shelf life of the Mallika cv. of mango fruits with the application of certain chemicals. The trial was conducted for two consecutive years (2015 and 2016) at Birsa Agricultural University, Kanke, Ranchi. The experiment was laid out under RBD with 14 treatments replicated thrice. The treatment comprised of KH2PO4 at 1 percent and 1.5 percent, K2HPO4 at 1 percent and 1.5 percent and all these four treatments were applied on 15th October (At fruit bud differentiation stage) and another eight treatments were the combinations of the above four chemicals with 1 percent KNO3 and with 1 percent Thiourea. These eight treatments were applied on 15 January (During bud break stage). All the above twelve treatments were applied as aqueous foliar sprays and altogether. There were two controls, one with water spray and another was no spray. Observations on flowering, yield and quality attributing characters such as size and weight of fruits, pulp percentage and chemical attributes were recorded. The observations on weight loss, spoilage loss, carotenoid content, marketability and organoleptic evaluation of fruits during storage were also carried out at alternate days. The results obtained revealed that plants sprayed with different chemicals had remarkable influence on fruit retention, yield and physico-chemical characteristics of fruits. Foliar application of KH2 PO4 (1%) + KNO3 (1%) was effective in twelve days earlier emergence of panicle whereas 05 days earlier flowerig was noticed with the application of KH2 PO4 (1.5%) +KNO3 (1%). Yield attributing factors suchas length, breadth, weight and number of fruits were achieved maximum with the chemical combinations with 1 percent KNO3. Number of fruits harvested per plant was maximum (88.54) in K2H PO4 (1.5%) + KNO3 (1%) whereas maximum (43.57kg) yield per plant was recorded with the application of KH2 PO4 (1%) + KNO3 (1%). In freshly harvested fruits the maximum TSS and total sugar with KH2 PO4 (1%) + KNO3 (1%), least acidity with K2H PO4 1% + Thiourea (1%) and maximum ascorbic acid with KH2 PO4 (1.5%) + KNO3 (1%) sprayed fruits were recorded. Potassium phosphate with potassium nitrate containing chemicals were found effective in reducing PLW and spoilage loss percent of fruits during storage and maintaining quality parameters of fruits during ambient storage and kept the fruits under marketable condition for longer than others and secured maximum organoleptic score on last day of storage.ThesisItem Open Access LINE X TESTER ANALYSIS FOR COMBINING ABILITY IN GLADIOLUS (Gladiolus hybridus)(Birsa Agricultural University, Ranchi, Jharkhand-6, 2017) Kispotta, Lily Maxima; Jha, K. K.The present investigation entitled “Line x Tester analysis for combining ability in Gladiolus (Gladiolus hypridus)” was taken up to evaluate some of the available germplasm of gladiolus for their future utilization in crop improvement programme. The line x tester analysis for combining ability was done with ten parents and twenty one crosses alone for different characts and percent of contribution by male and female parents for each character had been computed. The parents and crosses differed significantly for almost all the characters. The mean value of the crosses was at par with their respective parental mean in almost all the characters. The genotypic and phenotypic coefficient of variation was higher for character for the no. of florets open at a time, spike length and vase life. Large no. of crosses was found to give significant heterosis over mid parent and better parent. Sunset Sky x Eighth Wonder (23.58) for spike length (26.68), diameter of floret (20.34), number of floret open at a time (11.43) and vase life (23.61) was recorded maximum positive heterosis over better parent. Urmil x Candyman Showed maximum positive heterosis for number of floret per spike. Punjab Dawn was the best combiner for earliness for spike emergence (-17.49) and flower bud initiation. Sunset Sky recorded 2.14 gca effect which was the best general combiner for number of florest per spike. Summer Sunshine recorded 1.62 gca effect. The best combiner for diameter of floret was Summer Pearl with 2.59 gca effect. Among the lines Urmil -2.19 gca effects had recorded highest positive gca effect for vase life. In correlation study days taken for spike emergence, bud initiation, no. of floret per spike was found to be positively and significantly correlated with the days taken for the 1st floret to open, no. of floret open at a time, spike length and vase life.ThesisItem Open Access STUDIES ON FLOWERING,, FRUITING BEHAVIOUR AND POST HARVEST QUALITY OF SOME NON--DESCRIPT GENOTYPES OF LITCHI (Liitchii chiinensiis Sonn..)(Birsa Agricultural University, Ranchi, Jharkhand-6, 2017) Kumari, Swati; Jha, K. K.Litchi (Litchi chinensis Sonn) is a juicy fruit originated from southern China. It is the most popular member of family Sapindaceae and sub-family Nepheleae which is native of sub-tropical China (Groff, 1921). India is second largest producer of litchi next to China. In India litchi is cultivated mainly in Bihar, Jharkhand, West Bengal, Himachal Pradesh, Uttarakhand, Uttar Pradesh, Haryana and Punjab. Bihar ranks first in area and production of litchi. The edible portion of litchi fruit is a white to creamy coloured translucent pulp that surrounds a glossy and aromatic brown seed. At present many litchi varieties are available and they differ in yield, maturity, ripening period and physico-chemical properties. It is a general observation that better quality fruits fetch good price. Hence comparison of different litchi cultivars need to be explored with a view to find out the most suitable cultivar having quality fruits for fetching lucrative income to the orchard owners. The present study comprised various aspect of different non-descript genotypes of litchi grown at experimental farm of Ranchi Agriculture College, Kanke, Ranchi. As litchi fruits are highly perishable in nature, it suffers from high post harvest losses (upto 50%). Wherever it is grown, its shelf life under ambient conditions is never more than 24 to 72 hours (Kumar et al., 2004). Considering these things, the present study was undertaken to find out the best suitable genotype adapted to this region and to identify best suited cushioning material to enhance the shelf- life of litchi during the year 2015 and 2016. Different observations were taken and the results revealed that the minimum days for panicle emergence (27.12 days), initiation of flowering (53.87 days) and 50% flowering (63.37 days) was recorded in genotype 1. Maximum fruit set (38.47%) and retention (39.73%) of fruits was observed in genotype 1. Yield was found maximum in genotype 1 (109.49 kg/tree). Maximum fruit length (3.49 cm), breadth (3 cm), Weight (25.34 g) and volume (22.90 cc) was observed in genotype 1. Number of tubercles was found maximum in genotype 1 (163.25). Genotype 1 showed maximum aril (69.97%) and juice percentage (51.86%) of fruits. In the same treatment i.e. genotype 1, stone percentage (14.93%) and peel percentage (14.35%) was found minimum. Fruit cracking was found minimum in genotype 11 (13.73%). Results obtained in regard to physic-chemical properties of litchi fruits reveal that maximum TSS (20.300B) and minimum titratable acidity (0.48%) was observed in genotype 1. TSS:acid ratio (42.1) was also found maximum in genotype 1. Whereas, ascorbic acid was recorded maximum with genotype 11 (42.32 mg/100 g of pulp). Total sugar (14.12%) and reducing sugar (10.52%) was observed maximum in genotype 1. B:C ratio was also found maximum in genotype 1. Physiological loss in weight and volume of litchi fruits increased with increase in the duration of storage. However, cushioning of stalkless fruits with shisham leaves stored at freezing temp. resulted in significantly less loss as compared to control and other treatments. Significantly high TSS and ascorbic acid content was recorded under similar treatment. Decline in the acidity of litchi fruits with increase in storage time was observed. TSS: acid ratio was high when fruits were stored at freezing temp. and cushioned with shisham or litchi leaves. No significant effects of treatments tested on total sugar, reducing sugar and non-reducing sugar upto 7th day of storage. However, cushioning of stalkless fruits with shisham leaves stored at freezing temp. resulted in high total sugar content. Hence genotype 1was most suitable regarding reproductive, physical and physicochemical parameters of fruits. Cushioning of fruits with shisham leaves and storage at freezing temp. enhances shelf life of fruits.ThesisItem Open Access EFFECT OF ZINC, BORON, CALCIUM AND GA 3 ON GROWTH, YIELD AND QUALITY OF STRAWBERRY (Fragaria ananassa Duch.) cv. DOUGLAS(Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2013) Singh, Jagvinder; Sengupta, S.The strawberry (Fragaria ananassa Duch.) is one of the most important soft and delicious fruits of the world. It is a native of temperate regions, but it has adapted well to different climates viz. moderate, Mediterranean, subtropical even at high altitudes of tropical climate. Botanically it is an aggregate fruit, widely appreciated for its characteristic aroma, bright red colour, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in prepared forms such as preserves, fruit juice, ice-creams and milk-shakes. The fresh strawberry fruits are rich source of vitamins and minerals. Strawberry contains about 0.55% pectin (as calcium pectate).It is fairly good source of Vitamin-A (60 IU/100 g of edible portion) and Vitamin-C (30-120 mg/100 g of edible portion). The mature soft fruit contains about 5.0% total sugar and 0.50%-1.85% acidity. The crop is gaining popularity in the plateau region of Jharkhand, especially in Ranchi, due to congenial climatic conditions, but there is lack of information regarding its cultivation, application of secondary & micro-nutrients and plant growth regulators especially gibberellic acid. The experiment was conducted during 2012-13 at experimental unit of the Ranchi Agriculture College, B.A.U., Ranchi with seventeen treatments of different concentration of zinc sulphate (0.2 & 0.4 %), borax (0.1 & 0.2 %) and calcium nitrate (0.5 & 1.0 %) alone, combined and their combination with GA3 (100 ppm) with water spray as control. Treatments were replicated thrice in randomized block design. First application was applied at sixty days after transplanting and thereafter three times at fifteen days intervals. Result revealed that different concentration of zinc, boron, calcium and GA3 application significantly affected the plant growth, yield and quality as well as shelf life of fruits. Maximum plant height (28.46 cm), East-West spread (36.44 cm) & North-South spread (33.35 cm), no. of leaves (32.27), leaf area (28.40 cm2) and no. of runners per plant (15.47) were recorded with zinc sulphate (0.4%) + borax (0.2%) + calcium nitrate (1.0%) + GA3 (100 ppm) application. The minimum days taken to first flowering (72.60 days), first fruit set (4.13 days), colour development (2.13 days) and maturity of fruits (22.47 days) were also found with the application of zinc sulphate (0.4%) + borax (0.2%) + calcium nitrate (1.0%) + (GA3) (100 ppm) combination. Quality and yield attributing characters viz. the maximum no. of flowers (28.93), no. of fruits (22.40) per plant and maximum fruit length (4.28 cm), breadth (2.88 cm), volume (10.12 cc), average fruit weight (10.47g), juice (75.20%), TSS (13.33° Brix), acidity (1.108%), total sugar (8.62%), reducing sugar (6.69%), ascorbic acid (67.65 mg/ 100g fruit) content and maximum shelf life of fruits under ambient condition (3 days) were observed with the same treatment combination of zinc sulphate (0.4%) + borax (0.2%) + calcium nitrate (1.0%) + GA3 (100 ppm). Due to better vegetative parameters and yield attributing features, the maximum yield (116.34q/ha) was obtained with treatment zinc sulphate (0.4%) + borax (0.2%) + calcium nitrate (1.0%) + GA3 (100 ppm) which produced maximum net profit (Rs. 6,07,224/ ha) and the benefit cost ratio was 2.09 as per the recorded observations. So it can be inferred that significant increase in growth, yield and quality as well as shelf life of strawberry cv. Douglas could be obtained by the application of Zinc Sulphate (0.4%) + Borax (0.2%) + Calcium Nitrate (1.0%) + GA3 (100 ppm).ThesisItem Open Access EFFECT OF ORGANIC SOURCES OF NUTRIENTS ON GROWTH, YIELD AND QUALITY OF STRAWBERRY (Fragaria ananassa Duch) cv. DOUGLAS(Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2013) Tudu, Sushila; Misra, SanyatStrawberry is an important soft, attractive, Juicy, tasty and nutritious fruit. The taste of fruit mainly depends on three factors viz. sugar, acid and aromatic compounds. The fresh strawberry fruit is a rich source of vitamins A, B, and C. It also contains proteins and minerals like Iron, calcium, phosphorus, potassium and magnesium etc. Strawberry has medicinal properties like anti-carcinogenic, anti-septic, and anti-oxidant. Botanically, strawberry is an aggregate fruit called etaerio of achenes. The fruit of strawberry is complete fruit with 98% edible portion. The edible portion is succulent and thalamus of flower (Receptacle with numerous achenes). Strawberry is mainly a crop of temperate climate but it is also grown in subtropical region also. Potentiality of strawberry cultivation under Ranchi condition is high but there is lack of information regarding its cultivation, nutrient requirement among the common people and farmers. Hence, an experiment was carried out to study the effect of organic sources of nutrients on growth, yield and quality of strawberry. Out of thirteen treatments in the experiment conducted during the course of investigation T10- FYM (7.5 t/ha) + Vermicompost (3.18 t/ha) + PSB (5 kg/ha) + Azotobacter (5 kg/ha) showed the remarkable results in majority of the parameters i.e. growth, flowering characters, yield and yield attributing characters. This treatment also helped in enhancing the qualitative parameters of this crop i.e. Maximum plant height (21.22cm), Plant spread E-W (33.60cm), Plant spread N-S (31.03cm), Number of leaves per plant (28.25), Leaf area(16.03 cm2), Number of runners per plant (13.66), Number of flowers (27.45), Length of flower stalk (13.95 cm), Number of fruits per plant (19.66), Yield per plant (0.166kg), Yield per plot (6.00kg), Yield per hectare (66.66q), Fruit breadth (2.66cm), Fruit length (3.89cm), Juice percentage(85.23), Volume of fruit (8.16cc), TSS (12.41°Brix), Ascorbic acid (90.94mg/100), Reducing sugar (6.5%), non-reducing sugar (0.62%), Total sugar (7.57%) and shelf life of fruits at ambient condition (2.83days) were recorded when application of FYM, Vermicompost, PSB and Azotobacter was done in mentioned rate. So far as the economics of the strawberry crop is concerned, the application of FYM (7.5 t/ha) + Vermicompost (3.18 t/ha) + PSB (5 kg/ha) + Azotobacter (5 kg/ha) recorded maximum net return (Rs. 9,99,900 per ha) and B: C ratio (2.17). Based on these observations, it can be concluded that the combination of FYM, Vermicompost, PSB and Azotobacter gives best results regarding growth parameters, flowering characters, physical parameters, physico-chemical characteristics, yield attributes and economics of strawberry cultivation under Ranchi conditions.ThesisItem Open Access RESPONSE OF PGR AND MICRONUTRIENTS FOR QUALITY FLOWER PRODUCTION IN TUBEROSE (Polianthes tuberosa) UNDER PROTECTED AND OPEN CONDITIONS(Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2013) Rani, Rupa; Kumar, PrashantTuberose (Polianthes tuberosa) is one of the most important bulbous flowering ornamentals and has a unique place in the cut flower trade. It belongs to the family Agavaceae and is native to Mexico. Now, floriculture is emerging as a potential business due to divergence of farmers towards high value floral crops and utilization of flowers in social and industrial level. With the commercialization of floriculture, demand for tuberose in the national and international trade is increasing due to its importance as cut flower, loose flower,production of essential oil and for use in perfumary industry. Poor spike quality, low productivity and less vase life in the existing practices are the major constraints of tuberose cultivation under Jharkhand conditions. Keeping in view the above facts, research on quality flower production of tuberose under agro-climatic situation of Jharkhand was designed with two experiments. In the first set of experiment the response of tuberose to the foliar application of plant growth regulators and micronutrients such as GA3, MH, boron and zinc in single as well as in combinations were investigated. In the second experiment vase life of tuberose in different holding solution of various chemicals were studied. The first experiment was laid out in randomized block design with three replications and the crop was raised under two growing environments i.e. open and polyhouse conditions. In the first experiment tuberose grown under polyhouse exhibited superior results in respect of vegetative, flowering and bulb parameters. Maximum spike length of 87.38cm was recorded in open and 117.59cm in polyhouse conditions with foliar spray of GA3 (100ppm) +B (100ppm) +Zn (10ppm) and it was followed by GA3 (100ppm) +B (100ppm) spray with spike length of 86.83cm and 112.40cm in open and polyhouse respectively. Number of spikes per plant(1.33 in open and 2.7 in polyhouse) , number of florets per spike(40.57 and 59.10 in open and polyhouse), maximum floret weight per spike (58.64g) in polyhouse and vase life (10.52days) in tap water were also exhibited by application of GA3(100ppm)+B(100ppm)+Zn(10ppm). Foliar application of MH (500ppm) +B (100ppm) +Zn (10ppm) resulted in maximum diameter (4.18 cm in open and 5.14 cm in polyhouse) of florets. Significantly higher number of bulbs (8.08 in open and 8.31 in polyhouse) and weight of bulbs per plant (126.82g in open and 176.65g in polyhouse) were shown by GA3 (100ppm) +B (100ppm) +Zn (10ppm) Spray while, maximum diameter of bulb (2.13cm in open and 2.70cm in polyhouse) was shown by foliar spray of MH (500ppm) +B (100ppm) +Zn (10ppm). On the other hand, the second experiment was laid out in completely randomized design with four replications with an objective to study the vase life of tuberose in different solutions at room temperature viz., sucrose (4%), AgNo3 (100ppm), Carbendazim (0.2%), Bleaching powder(50ppm), Sucrose (4%)+ AgNo3 (100ppm), Sucrose (4%)+ Carbendazim (0.2%), Sucrose (4%)+ Bleaching powder (50ppm), Control (water). Use of Sucrose (4%) +AgNo3 (100ppm) as vase solution resulted in maximum uptake of water (57.31g/3spikes) followed by Sucrose (4%) + Carbendazim (0.2%). Sucrose (4%) + Bleaching powder (50ppm) solution showed maximum loss of water (52.03 gm/ 3 spikes). Maximum vase life (15.57days) with highest floret opening (84.48 %) was obtained in the vase solution of Sucrose (4%) +AgNo3 (100ppm).ThesisItem Open Access STANDARDIZATION OF NUTRIENT AND WATER MANAGEMENT STRATEGIES FOR INCREASING PROFITABILITY OF ULTRA HIGH DENSITY GUAVA (Psidium guajava L.)(Birsa Agricultural University, Kanke, Ranchi, Jharkhand, 2015) Shanker, Karuna; Jha, K.K.Guava (Psidium guajava Linn.), the most common fruit of sub-tropical areas originated from tropical America belongs to family Myrtaceae, also known as “apple of tropics”. It is considered as poor man’s apple due to cheapness and high nutritive value in addition to its availability in the market. A field experiment was conducted for two consecutive years (2012-2013 and 2013-2014) on 5 year old guava orchard of cv. Sardar planted at a spacing of 1.0 m x 2.0 m in Ranchi. The objective of this investigation was to standardize nutrient and water management strategy for increasing the yield and fruit quality of guava under Jharkhand conditions. The experiments were set up in a split plot design with four fertilizer doses 100%NPK i.e.580 g N, 270 g P, 400g K/plant; 60%NPK i.e. 348gN, 162gP, 240g K/plant; 40%NPK i.e. 232gN,180gP 160g K/plant; 20%NPK i.e.116gN 54gP 80g K/plant as main plots and four different foliar sprays as boric acid(0.4%), zinc sulphate (0.2%),boric acid(0.4%)+ zinc sulphate(0.2%) and water spray as sub plots with four replications. The NPK fertilizer dose was applied at an interval of every two months during June 12 to April 14 (Total of twelve times/ two year) in a 1m radius around the tree trunk (drip line of trees). The foliar application of micronutrients was sprayed at the rate 750 ml/ tree at flowering and fruit set stage during June 12 and August 14 (Total of Four times/ two year). In our 2 year study, the experimental results clearly indicated that 60% NPK fertilizer dose resulted in maximum trunk girth (55.33mm) and girth of primary branches (43.77mm), while, maximum per cent increase in trunk girth( 15.81%) and girth of primary branches( 18.62%) were recorded in 100% NPK fertilizer dose. However, maximum number of flowers per plant (18.66), number of fruits per plant (17.10) and fruit weight/ plant (3.65kg/plant) recorded in 100%NPK fertilizer dose, which was at par with 60% NPK Fertilizer dose. Highest TSS (11.73 oBrix) value was recorded in foliar application of boric acid (0.4%)+zinc sulphate(0.2%). The highest available nitrogen was 92.07 and 73.95 g/plant respectively in surface and subsurface soil layer respectively with application of 100% NPK fertilizer dose. Highest available potassium was 120.53 and 104.54 g/plant respectively in surface and subsurface soil with the application of 60% NPK fertilizer dose. Further, phosphorus content was 27.17 g/plant in surface soil with 100% fertilizer dose, while highest available phosphorus content was 15.96 g/ plant of 40% NPK in subsurface soil. The highest leaf nitrogen content was 2.60 % with foliar spray of ZnSO4 (0.2%), highest leaf phosphorus content was 0.18 % with foliar spray of boric acid (0.4%). Highest leaf potassium (1.12%), zinc (40.35mg/kg),copper(30mg/kg),manganese(2062.33mg/kg) and boron (27.94mg/kg) was recorded with foliar spray of boric acid (0.4)+ zinc sulphate (0.2%). The highest nitrogen content in leaf was 2.58% in 100% NPK, highest phosphorus content in leaf was 0.18% in 40 %NPK. Application of 60% of NPK fertilizer dose resulted in highest potassium (1.13%), iron (548.18 mg/kg), copper (29.45 mg/ kg) and manganese (3208.50 mg/kg). Similarly the zinc content was 37.64 mg/kg in 20%NPK and boron content was 29.37 mg/ kg in 100% NPK. Hence, it is recommended that application of 60% of recommended dose of NPK in soil and foliar application of Zinc sulphate (0.2%) + Boric acid (0.4%) can maximize the yield and quality of fruits under ultra high density guava orchard. The experiment on standardization of water management strategy for ultra high density guava orchards A field experiment on drip irrigation scheduling in ultra high density guava orchard was conducted in five years old trees of Lucknow- 49 guava. Four levels of open pan evaporation based drip irrigation schedules (20, 40, 60, and 80% pan evaporation replenishment) and one rainfed plot to serve as control. Each treatment contained 12 plants per unit with four repetitions for each treatment. The experiments were arranged in randomized block design. Maximum irrigation water use efficiency was found in tree grown under irrigation level at 20% of PE. The IWUE decreased with increasing quantity of water applied. Application of irrigation at 60 % PE has shown better plant growth and better fruit yields of guava planted at ultra-high density. Many physical plant parameters like increase in trunk girth, number of fruits and fruit weight were observed to be better under this treatment. Also, reducing the quantity of water applied from 100% PE to 60% PE did not affect the fruit quality parameters. Therefore application of water at 60% of PE at two days irrigation interval is recommended for commercial cultivation of guava under ultra-high density planting pattern.
