This study was conducted in lath house of Mussaib Technical College during the growing season 2020-2021 to know the role of fertilizers and foliar feeding with nano-fertilizer and the amino acid DRIN in some chemical traits and leaf nutrient content of one-year-age fig seedlings.It was implemented as a factorial experiment (4*3*3) with a completely randomized design and with three replications. The experiment included three factors if the first factor included: four ground additions of biofertilizers, namely (BioHealth WSG at a rate of 10 g. pot-1 and mycorrhiza 10 g. Pot-1 and a mixture of Mycorrhizae and BioHealth WSG at average of 10 g Pot-1) in addition to the control treatment. As for the second factor, it included three levels of foliar feeding with Chelated Nano Fertilizers (KHAZRA), which are 0, 2, 4 g.L-1, while the third factor included three concentrations of foliar nutrition with DRIN, which are 0, 4, 8 ml. L-1. The results confirmed the excelled triple interaction treatment between (ground addition between Mycorrhizae and BioHealth WSG at average of 10 g. pot-1 and foliar nutrition with nano-fertilizer at a concentration of 4 g.L-1 and amino acid DRIN at a concentration of 8 ml.L-1) significantly on all treatments in the chemical properties (chlorophyll and carbohydrates) and the nutrients content of the leaves (nitrogen, phosphorous, potassium, iron and manganese).

The Integrated Approaches to the Productivity Management of the Grape Plantations of Different Ages

The article highlights the generalized research data of the Department of Horticulture, Viticulture, Biology and Chemistry of Odessa State University. The main direction of its work is to maintain the productivity of existing plantations and the formation of high-yielding plantations of grapes of technical varieties in the Northern Black Sea region of Ukraine. Based on many years of research, the productivity of vineyards of Aligote, Traminer pink, White fetish, Chardonnay, Pinot Noir, Cabernet Sauvignon and many others has been established, as well as complex schemes of impact on young grape bushes and plantations older than 25 years. As a result of researches, the basic optimum terms for conditions of the South of Ukraine in which it is necessary to carry out processing by growth stimulators and root and foliar feeding are established. These terms are: the first treatment before flowering, the second when the berries reach the size of a pea and the third at the beginning of ripening berries. It is proved that the after-effect of application of fertilizing elements is intensified on old plantations after the renewal of the plantation and can last up to three years, depending on the wet supply of the territory. The main conclusions and proposals for the use of complexes of agricultural technology elements based on root and foliar nutrition with different substances, irrigation, periodic deep tillage is given. Based on the obtained results, a mathematical model of quality management of grape products and products of its processing is developed

Effect of Foliar Nutrition and Crop Geometry on Cultivars of Blackgram in Shiwalik Foothills of Jammu

Background: Rapid expansion in population increased the global food demand. To meet this surge in demand for food and to ensure food and nutritional security addition of pulses in the cropping system is a visible alternative. Pulses intensifies cropping intensity, enhances health and fertility status of the soil and acts as a good source of dietary protein etc. However, due to a wide gap between the potential and actual yield of pulses in rainfed areas. Hence, identification and adoption of best management practices has become a pre-requisite. The present study was undertaken as the information available on foliar nutrition and different crop geometries on performance of different blackgram genotypes in rainfed condition is meagre. Methods: In this investigation conducted during kharif season of 2018 at Advanced Centre for Rainfed Agriculture, SKUAST-Jammu, Rakh Dhiansar. The experiment was laid out in factorial randomized block design with 3 factors and 3 replications. The factor-1 consisted of three blackgram cultivars (Uttara, PU-31 and Mash-114), factor 2 consisted of two crop geometries (30×10 cm and 45×10 cm) and factor-3 consisted of three foliar nutrition (Foliar spray of molybdenum as sodium molybdate @ 0.1% at 20 DAS, Foliar spray of 1.5% KCl at flowering and Foliar spray of molybdenum as sodium molybdate @ 0.1% at 20 DAS fb 1.5% KCl at flowering). Result: The results from the present investigation indicated that adoption of Mash-114 at 30×10 cm crop geometry, supplemented with foliar application of molybdenum as sodium molybdate @ 0.1% at 20 DAS fb 1.5% KCl at flowering could be a viable technological proposition under rainfed conditions of Jammu.

Rootstock Affects the Fruit Quality of ‘Early Bigi’ Sweet Cherries

The cherry rootstock influences the performance of the scion cultivar. It has an effect on cherry fruit quality, tree growth, yield and yield efficiency and floral and foliar nutrition. In this work, the influence of Saint Lucie 64 and Maxma 60 rootstocks on the fruit quality traits of cv. Early Bigi was evaluated. For this, several parameters, namely fruit weight (FW) and size (FS), soluble solids content (SSC), pH, titratable acidity (TA), flesh firmness (FF), epidermis rupture force (ERF), color and sensory profile, were assessed. Results showed that the fruits from trees on Saint Lucie 64 presented higher FF and ERF values and, consequently, better texture. On the other hand, fruits from trees on Maxma 60 showed sweeter cherries (higher SSC). Moreover, these trees presented the darkest cherries (lower values of L*, a*, b*, C* and hue°) and the highest SSC. Therefore, although the trees on Saint Lucie 64 produced firmer cherries, it was those with the Maxma 60 rootstock that produced sweeter and darker fruits. In conclusion, both scion–rootstock combinations proved to be good options for the region of Resende.

Effect of Foliar Application of Water-Soluble Fertilizers for Yield and Economics of Rice Fallow Blackgram (Vigna mungo (L). Hepper)

Field experiment was conducted at farmer field in kadukkarai village, Kanyakumari during February 2021 – April 2021 to evaluate the Effect of foliar nutrition for maximizing the productivity of rice fallow blackgram (Vigna mungo (L). Hepper). Nine treatments were tested in randomized block design with three replications. Among the treatments, application of RDF + Foliar spray of 1% 19:19:19 on 15 DAS + Foliar spray of 1% 12: 61:0 30 DAS + Foliar spray of 1% 13:0:45 on 45 DAS significantly recorded highest grain yield (723 kg ha-1) and haulm yield (2320 kg ha-1). However, the highest gross return (Rs.53, 955), net return (Rs.41, 305) and BC ratio (3.27) were recorded the foliar spray of 1% 19:19:19 on 15 DAS + Foliar spray of 1% 12: 61:0 30 DAS + Foliar spray of 1% 13:0:45 on 45 DAS.

Foliar nutrition on 60 and 90 days after sowing was done with 2% DAP, 4 % cowpea sprout extract and 4 % horsegram sprout extract were applied. Seeds hardened with 2% Pink Pigmented Facultative Methylotroph (PPFM) for 12 hrs and foliar spray with 4 % cowpea sprout extract on 60 and 90 days after sowing recorded significant enhancement in productive tillers, seeds /panicle, 1000 seed weight and 11 per cent higher seed yield than the control.

Performance of papaya variety ‘Surya’ under fertigation and foliar nutrition

Effects of fertigation and foliar nutrition with micronutrients on papaya flowering, yield and fruit quality parameters were studied during the period 2018 – 2020 at Instructional Farm, College of Agriculture, Vellayani, Thiruvananthapuram, Kerala, India. A field experiment consists of 14 treatments replicated thrice was laid out based on randomized block design. A combination of four fertigation doses of 75 %, 100 %, 125 % and 150 % Recommended Dose of Fertilizers (RDF) of N (304.89, 406.52, 508.15 and 609.78 gm urea plant-1 year-1 respectively based on soil test data in 76 fertigation) and K (426.25, 568.33, 710.42 and 852.50 gm muriate of potash plant?¹ year?¹ respectively based on soil test data in 76 fertigation) and three foliar sprays (1.0 % 19:19:19 at bimonthly interval starting from 4 MAP (Month After Planting) to 16 MAP, 0.5% ZnSO4 + 0.3% borax at 4th, 8th, 12th and 16th MAP and water spray at bimonthly interval starting from 4 MAP to 16 MAP) where compared with soil application of recommended dose of NPK (187:170:341 g NPK plant-1 year-1 based on soil test data) (control 1) and 187:170:341 g NPK plant-1 year-1 based on soil test data as organic manures as combination of FYM (Farm Yard Manure), poultry manure and vermicompost in the ratio of 2:1:1 (control 2). Application of 100 % recommended dose of N and K through fertigation at weekly interval from one MAP to 20 MAP and foliar sprays of 0.5 % ZnSO4 and 0.3 % borax at 4th, 8th, 12th and 16th MAP (T5) initiated earliness in flowering (142.67 days) and harvest (275.00 days). However, plants receiving 100 % recommended dose of N and K through fertigation at weekly interval from one MAP to 20 MAP with foliar sprays of 1% 19:19:19 at bimonthly interval starting from 4 MAP to 16 MAP (T4) significantly improved the fruit weight, number of fruits per plant and total yield per plant in papaya variety ‘Surya’ and it was on par with T5. Fruit quality parameters namely TSS (Total Soluble Solids), ascorbic acid and total sugars were found significantly highest in T5 and lowest titratable acidity was also recorded in T5. Hence, treatment T5 which is found superior in initiating early harvest, with higher yield and good quality characters in papaya variety ‘Surya’ can be recommended to farmers.
