“…The application of auxins caused translocation of hormones, food substances and other factors stimulating fruit formation to the tissues of ovary in greater amount which resulted in higher fruit set [9]. Similar results are reported by Gurjar [10], Dhillon et al [11] Agnihotri et al [12], Brar et al [13] Jain and Dashora [14], Singh and Dhaliwal [15], and Pandey et al [16].…”

The present investigation entitled “Regulation of summer season flowering to enhance the Flowering and physical parameters of mrig bahar in guava (Psidium guajava L.) cv. Lucknow-49 under sodic soil” was carried out at Production Processing of Usar Waste Land Akma, Department of Fruit Science, Acharya Narendra Deva University of Agriculture and Technology, Narendra Nagar (Kumarganj), Ayodhya (U.P.) during 2021-22. The experiment was conducted in a Randomized Block Design with three replications and ten treatments. The treatments were Urea (15, 20 and 25%), NAA (75, 150 and 225 ppm), 2,4-D (20, 40 and 60 ppm) and control applied on second week of April. The results denoted that all the treatments were emphatic in summer deblossoming and enhanced the physical attribute of fruits throughout both season over the control, however, maximum yield per plant, maximum no. of fruits per plant, maximum fruit set percentage and minimum flower drop percentage was recorded with control in rainy season. The profitable effects of the treatments tried were observed to be more prominent in winter season crop than the rainy season crop. Among the treatments, deblossoming with Naphthalene Acetic Acid (NAA) 225 ppm showed maximum enhancement in Flowering characters viz. Percent flower drop (%), Percent fruit set (%) and fruit physical characters viz. Number of fruits per plant, fruit length (cm), width (cm), weight (g), fruit yield per plant (kg/tree) over the control in winter season as well as in rainy season crop.

“…Understanding of crop regulation will help to optimize harvest time which reduce surplus in the market, to obtain higher price of the produce, to avoid spoilage due to excessive production at a particular time, to provide employment throughout the year and balance the trade and to reduce imports. Gurjar et al, (2018) obtained maximum and statistically higher yield (119.73 q/ ha. ), gross return (Rs 32925 per hectare) and net return (Rs 230529 per hectare) under application of 800 PPM NAA plant growth regulator.…”

Guava (Psidum guajava L) is one of the most promising fruit crops of India and is considered to be one of the exquisite nutritionally valuable and remunerative crops. In recent years guava is getting popularity in the international trade due to its nutritional value and processed products. It is hardy, prolific bearer and highly remunerative fruit crop. Its cultivation is done on the commercial scale. There are mainly three bahar season of the guava fruit viz., Ambe bahar, Mrig bahar and Hasth bahar. Continuous bearing results in reduction of yield with small size fruits. The heaviest flowering is observed in rainy season cropping, but, the fruits of this season crop are rough, insipid in taste, poor in quality, less nutritive and are heavily attacked by many insects, pests, and diseases. In order to overcome this problem and to force a full crop in any of the three seasons, as required by the grower and the traders, bahar treatment is practiced. The main objective of crop regulation is to force the tree for rest and produce profuse blossom and fruits during any one of the two or three flushes. The methods to be followed for crop regulation depend on climatic factors, cropping pattern, extend of the damage by the disease and pests, market and industry demand, cultivar, etc. Crop regulation is achieved by the various techniques like water management to induce stress, pruning of shoots and roots at different levels and at different times, training of shoots and manual or chemical thinning of flowers.

“…According to research, maximum and statistically higher yield (119.73 q/ha), gross return (Rs. 32925 per hectare) and net return (Rs 230529 per hectare) as well as cost benefit ratio (1:3.33) were obtained under the application of 800 PPM NAA plant growth regulator [58]. Similarly, it was reported that a significantly higher yield (100 kg/tree) was found in Allahabad Safeda with the spray of 10% urea during the winter season, while Sardar guava recorded the highest yield (103.98 kg/tree) with the spray of 1800 ppm ethephon during the same season which was closely followed by 20 and 15% urea (100.25 and 96.38 kg/tree, respectively) [10].…”

Guava (Psidum guajava L.) is one of the most favorable fruit crops in India and is considered to be a well-executed, nutritionally valuable and profitable crop. Recently, guava has secured higher demand within the global trade because of its nutritional value and processed products. It is a hardy, prolific bearer and produces a fairly remunerative fruit crop. It is mainly cultivated on a large commercial scale. Guava fruit bears three bahar seasons, viz., Ambe bahar, Mrig bahar, and Hasth bahar. The continual bearing habit ends up in the reduction of yield with the inferiority of small-sized fruits. So as to overcome this problem, bahar treatment is practiced. Among the three bahar seasons, the heaviest flowering is observed in the Ambe Bahar season, but the fruit quality of this season is rough, watery, insipid in taste, poor in quality, less nutritive and is heavily attacked by many insects, pests and diseases. The fruit quality of winter season crops is excellent, nutritive, and escaped from the attack of fruit flies. Therefore, the crop regulation practice is to force the tree for rest and produce profuse blossoms and fruits throughout any one of the two or three flushes. It is necessary to reduce the fruit set during the rainy season and subsequently increase the fruit set during the winter season through the use of various chemicals like NAA, ethereal and urea etc to regulate the guava crop. This method aims at regulating uniform and good quality fruit and also maximizing produce as well as profit. This regulation method depends on climatic factors, cropping pattern, extend of the damage by the disease and pests, market and industry demand, cultivar, etc. Crop regulation is accomplished by the various strategies like water management to induce stress, training and pruning of shoots and roots at different levels as well as at different times and manual or chemical thinning of flowers.
