Among subtropical fruits Ber (Zizyphus mauritiana L.) one of the most common fruit crop, grown under neglected soil types. It is a drought hardy and can grow under the most hazardous conditions of soil, water and climate and thus it has rightly been recommended for the arid and desert area of India [1]. It is found growing wild as well as in cultivated forms throughout the warmer regions up to an altitude of 1500 metres above Mean Sea Level. The experiment comprised 13 treatments consisting of foliar spray of GA3, NAA, Urea and control. The treatments are as follows- T0 Control (water spray), T1 (GA3 @10 ppm), T2 (GA3 @20 ppm), T3 (NAA @20 ppm), T4 (NAA @40 ppm), T5 (Urea @1.0%), T6 (Urea @1.5%), T7 (GA3 @10 ppm + NAA @20 ppm + Urea @1.0%), T8 (GA3 @20 ppm + NAA @40 ppm + urea @1.5%). Mentioned solutions with different concentration were sprayed by foot sprayer in the morning hours and selected branches were fully drenched. On the basis of sprays of plant growth regulators i.e. GA3 and NAA and urea as well as their combined treatments influenced different parameters in this research trial. The combined treatments of GA3 20 ppm + NAA 40 ppm + urea 1.5% maximized initial fruit set, fruit retention, fruit volume, length of fruit, fruit diameter, fruit weight, pulp weight, pulp/stone ratio and minimized the fruit drop, stone weight content. The second effective treatment was GA3 10 ppm + NAA 20 ppm + urea 1.0% identified in present investigation.

An experimental trial was carried out during the season from March 2018 – June 2018 at the Horticulture farm of Lovely Professional University, Phagwara (Punjab). utilising a randomised block design, the experimental trial consists three replications. The current study included eleven treatments, including a control with different PGR dosages of Maleic hydrazide (200, 250, and 300 ppm, MH), Naphthalene acetic acid (50, 100, and 150ppm, NAA), and Gibberellic acid (50,100 and 150 ppm, GA3). Based on the results of the experiment, it was concluded that the treatment T8 (100 ppm GA3) significantly affected the cucumber's fruit yield parameters and treatment T7 (50ppm GA3) showed the better results in quality attributes Viz., TSS and fruit texture.

A field experiment was carried out in the pot culture of Soil Science and Agricultural Chemistry, C S Azad University of Agriculture & Technology during 2017-18. The experiment consisted 9 treatments viz.

Introduction and Aim: Pointed gourd (Trichosanthes dioica Roxb) is one of the most profitable and nutrient-rich summer crops. The present investigation entitled “Effect of Integrated Nutrients Management Practices on Growth and Yield of Pointed gourd (Tricosanthes dioica) cv. Papdi & Rudra’’ was carried and conducted at open field condition located at Horticulture Research Centre (HRC), at Sardar Vallabhbhai Patel University of Agriculture & Technology, Meerut U.P India during Kharif season of 2022-2023. Methods: The experiment was carried out in randomized block design keeping two varieties i.e. Papdi and Rudra with three replications. The experimental trial consists 10 different treatment. Discussion and Conclusion: All the treatments showed significant differences for most of the traits under study, the combination of T9 (Vermicompost @ 10 ton /hac + Jivamrit @8% Spray) followed by the treatment T10 (F.Y.M @ 15 ton/ha + Jivamrita @ 8% sprays) was best suited for the growth attributes of pointed gourd.: Hence, the above treatment can be suggested as a combination for getting higher growth of pointed gourd.

An experiment was carried out at Department of Fruit Science, Sardar Vallabhbhai Patel University of Agriculture & Technology Meerut (U.P), India during two consecutive years i.e., 2021-22 and 2022-23 to assess the Influence of foliar Spray of NAA and Zinc on growth, flowering, fruiting, yield and quality of Guava (Psidium guajava L.) cv. L-49 under western U.P. conditions. The foliar spray of micronutrients along with plant growth regulators play an important role in manipulating many physiological phenomena, improving the yield and quality and enhanced the productivity of plants by fulfilling the nutritional needs of fruit crops. Twelve treatments viz., three level of NAA (0, 50, and 75 ppm) and four level of Zinc (0, 0.4, 0.6, and 0.8 %) with their combinations were used, which were replicated in factorial Randomized Block Design. Results showed NAA @75 ppm (N2) individually registered yield of 53.75 and 53.06 kg/plant the application of Zinc at 0.8 % (Zn3) concentration recorded yield of 53.86 and 53.17 kg/plant. Interactive effect of naphthalene acetic acid and Zinc (N2Zn3) treatments registered yield of 59.56 and 58.81 kg/plant while quality parameter pectin was in the range of 0.79 and 0.80 % with treatment naphthalene acetic acid @75 ppm (N2) and Zinc at 0.8 % (Zn3) individually recorded 0.80 and 0.82 % outperformed the other treatments. The combination could be ideal and recommended for the production of guava in the Indo-Gangetic plains in western India.
