Impact of plant growth regulators viz., benzyl amino purine (BAP - 50 ppm), brassinolide (BL - 0.5 ppm), and nutrient like KCl (1%) alone and with combination on growth and growth analytical parameters, and yield of finger millet by foliar spray at panicle initiation stage under rainfed condition was studied in field experiment. The treatments including control, KCl, BAP, BL, KCl + BAP, KCl + BL, BAP + BL and KCl + BAP + BL and different growth and growth analytical parameters were estimated. Combination of KCl, BAP and BL registered highest root length (17.2 cm), leaf area (425.3 cm2), leaf area index (1.82) and leaf area duration (55.7 days) compared to other treatments. Higher specific leaf weight and crop growth rate were recorded by KCl + BAP, and BAP + BL, respectively. The highest grain yield of 22.5 Q/ha was recorded by KCl + BAP + BL.

The present investigation was carried out in the plain areas of Chitwan to determine the promising plant growth regulators (PGR) promoting growth and yield of chilli cultivars Jwala and Suryamukhi during winter-summer season of 2003/2004. Suryamukhi ranked superior to Jwala for most of the yield attributing characters, whereas Jwala was better in vegetative characters than Suryamukhi. Among PGRs, 2,4-D at 2 ppm was better for fruit set, number of fruits per plant, fruit length, number of seeds per fruit, seed weight per fruits, 1000 seed weight and fruit yield where as NAA at 40 ppm gave the highest leaf area index (LAI). PGRs were ineffective in promoting flowering and fruiting during winter season. GA3 at 10 ppm exhibited maximum amount of ascorbic acid content. The treatments, 2 ppm 2,4-D, 5 ppm triacontanol, 40 ppm NAA and 10 ppm GA3 produced 28.75%, 25.70%, 13.61% and 2.30% higher fruit yield over control, respectively. The highest net profit and B:C ratio were recorded in case of 2 ppm 2,4-D. The use of GA3 as foliar spray was not economical.

ABSTRACT<br /><br />Use of shade on the cultivation of  potato in medium altitude is expected to reduce both light intensity and temperature, and therefore is more suitable for potatoes to grow in medium altitude. While the use of growth regulators subtances improving the process of assimilate distribution from the leaves to the tuber. Therefore  use of shade followed by plant growth regulators applications are expected to increase of  growth and yield. The objectives of the experiment were to determine growth and yield of  potato cultivar Atlantik grown  at medium  altitude with different types of shading and  plant growth regulators. The experiment was conducted at an experimental station of the Faculty of Agriculture, Padjadjaran University, Jatinangor, Sumedang, at an altitude 685 m asl. The experiment was arranged in  a split plot design  consisting of two factors and three replications. The main plots were types of shading (without shading, paranet 45%, UV polyethylene, and corn plant) and the sub plots were combination of plant growth regulators (benzylaminopurine + paclobutrazol), (benzylaminopurine +chloro choline chloride), benzylaminopurine, paclobutrazol, chloro choline chloride).  The results showed that the effect of interaction between shading and plant growth regulator on growth and yield of the potato were not significant. Paranet shade and corn plant shade  increased plant height, leaf area index, tuber weight per plant, yield  per hectar and tuber grade A of potato cultivar Atlantik. Corn plant shading gave potato yield 21.6 ton ha-1 with 64% grade A tuber. Paclobutrazol decreased potato plant  height,  but  increased  number  of  tuber per plant and yielded highest tuber weight of 702.1 per plant (23.3 ton ha-1 ), with 70.9% grade A tuber.    <br /><br />Keywords: Benzylaminopurine, microclimate, paclobutrazol, temperature

Background: The shading caused by maize inhibited the growth of soybean, reduced the yield of soybean under maize-soybean relay strip intercropping system. To investigate whether foliar spraying different types of plant growth regulators could improve the growth and yield of intercropped soybean.Methods: A field experiment was conducted in 2018 to evaluate the effect of foliar spraying 6BA (6-benzylaminopurine), S3307 (uniconazole) and DTA-6 (diethyl aminoethyl hexanoate), at the soybean beginning flowering stage, on the growth and yield of three soybean varieties (i.e., Nandou 25 (ND25), Gongqiu 8 (GQ8) and Guixia 3 (GX3)).Result: The leaf area index of three soybean varieties were highest in DTA-6 at 35 days after spraying (DAS) and no significant difference (p less than 0.05) were observed among three plant growth regulators. The chlorophyll a and chlorophyll b content under 6BA and DTA-6 treatments were significantly higher than CK and S3307 at 35 DAS. The activities of antioxidant enzymes (i.e., SOD (Superoxide dismutase) and CAT (Catalase) and antioxidant substances (i.e., GSH (Glutathione) were increased after spraying 6BA, S3307 and DTA-6 in three soybean varieties at 35 DAS. Independent soybean varieties, foliar spraying 6BA, S3307 and DTA-6 increased the soybean yield, pods per plant, 100-grains weight and grain per plant and the effect of DTA-6 (60 mg l -1) treatment were best than others.

Abstract Plant growth regulators and improved planting density are the innovative techniques in the establishment of more productive cotton crop. A field study was planned to assess the role of growth regulators in the resource utilization efficiency of cotton cultivars under different row spacing at Agronomic Research Area, Bahauddin Zakariya University Multan and Usmania Agricultural Farm, Shujaabad during Kharif 2012. The study was comprised of cotton cultivars viz. CIM-573 and CIM-598, cultivated under conventional (75 cm), medium (50 cm) and improved ultra-narrow row spacing (25 cm) and foliar spray of growth regulators viz. moringa leaf extract (MLE) and mepiquat chloride (MC), either alone or in combination, distilled water as a control. The application of MLE alone and in combination (MLE + MC) showed the promoting effect on crop growth rate, net assimilation rate, leaf area index, leaf area duration, sympodial branches and number of bolls leading to higher seed cotton yield of both cotton cultivars grown under conventional row spacing. While application of MC averts the plant growth without considerably improving the productivity. MLE being rich source of growth promoting hormone and nutrients showed its potential to a far greater extent under conventional row spacing in efficient utilization of available resources compared to MC and distilled water.

Pigeonpea is an important pulse crop and one of the major sources of protein in India. In the present study, investigations were undertaken to study the role of foliar spray of different plant growth regulators (PGRs) in altering morphology and enhancing the yield potential of pigeonpea varieties VBN 1, APK 1 and VRG 62. Among different plant growth regulators (PGRs) studied, foliar application of Giberellic acid (GA3) significantly increased plant height, number of leaves and branches in pigeonpea. This was followed by Brassinosteroid (BR). Foliar application of PGRs significantly increased both the growth attributes and yield. Various yield components viz., days to 50 per cent flowering, days to maturity, number of flowers per plant, number of pods per plant, number of clusters per plant, number of seeds per pod, hundred seed weight and harvest index were enhanced by PGR application. Maximum dry matter accumulation and fertility co-efficient was recorded in the treatment (T9), i.e., BR application @ 0.1 ppm than the other treatments. It is concluded that foliar application of BR @ 0.1ppm is advantageous in enhancing both growth and yield of Pigeonpea and thus BR foliar spray can be recommended for adoption by the farmers, to maximize the yield in Pigeonpea.

To improve the yield of sesame in Mekong delta of Vietnam, the study was conducted to find out plant growth regulator, micronutrient to increase growth and yield of black sesame. The experiment consisted of six treatments (NT) as follows: NT1: Control as no plant growth regulators and micronutrients, NT2: Spraying brassinolide at 50ppm, NT3: Spraying gibberellin at 100ppm and manganese at 0.05%, NT4: Spraying brassinolide at 1.25ppm, NT5: Spraying boric at 50ppm and molybdenum at 50ppm, NT6: Spraying selenium at 4ppm. The results showed that spraying plant growth regulators and micronutrients as single NAA, BR, Se and combined GA3 plus manganese, boric plus molybdenum at 27 and 35 days after sowing have not increased plant height and height to the first fruit in the first crop. Combination of spraying boric plus molybdenum or single selenium increased the number of capsules per plant, the number of seeds per capsule and resulted in higher sesame yield.
