Effects of Time of Pruning and Plant Bio-Regulators on the Growth, Yield, Fruit Quality, and Post-Harvest Losses of Ber (Ziziphus mauritiana) Shashi, Om Prakash Garhwal, Mali Ram Choudhary, Laxmi Narayan Bairwa, Kishan Lal Kumawat, Pradeep Kumar, Boris Basile, Giandomenico Corrado, Youssef Rouphael, Jagan Singh Gora Horticulturae, 2022 Indian jujube or ber (Ziziphus mauritiana Lam.) is a deciduous fruit tree typically cultivated in several semi-arid areas of Asia because of its adaptability to yield-limiting conditions. The present study aimed to assess the effect of four pruning times (i.e., the fourth week of March, second week of April, fourth week of April, and second week of May) and four treatments using stress-mitigating plant bio-regulators (thiourea at 500 ppm and 1000 ppm; salicylic acid at 100 ppm and 150 ppm) as a means to improve both fruit yield and quality post-harvest. To this end, a full factorial experiment lasting two growing seasons was carried out under field conditions in the representative semi-arid region of Rajasthan, the state with the largest production in India. We assessed the vegetative growth of the trees, the fruit size and yield, and some quality parameters (soluble content, acidity, ascorbic acid, and total sugars) as well as the main post-harvest traits (fruit weight loss and spoilage). Overall, pruning during the second week of April had the greatest positive influence on most of the variables studied. For instance, it induced the highest vegetative vigor, allowing the maintenance of relatively higher chlorophyll and relative water content in the leaves. The fruit parameters also responded most positively to the second week of April pruning, a treatment that, compared to the others, induced a higher diameter; a higher amount of TSS (19.6 °Brix), ascorbic acid (86.5 mg/100 g), and total sugar (10.4%); and a better post-harvest shelf-life. Among the plant bio-regulators, the application of thiourea at 1000 ppm had the highest positive influence on the growth parameters, yield, quality, and reduction in spoilage post-harvest. The differences between the doses of PBRs were limited.
Effect of weed management practices and nitrogen levels on weed intensity and bulb yield of onion in loamy sand soils Pushpa Ujjainiya, M. R. Choudhary Indian Journal of Horticulture, 2020 Field experiment was conducted on onion to develop efficient integrated weed management practicesunder various levels of nitrogen. Two hand weeding at 20 and 40 DAT or application of pendimethalin (PP) +oxadiargyl at 40 DAT or application of pendimethalin (PP) fb 1 HW at 40 DAT combined with 100 kg N ha−1 were recorded significantly higher bulb weight, bulb yield and net returns. Thus, either of above integrated weedmanagement practice can be used for rabi (winter) season onion in loamy sand soils.
