“…Jan et al ( 2019) observed that plots receiving the highest nitrogen dose achieved the highest yield at 14748 kg ha -1 , whereas the control plots had the lowest fruit yield at 3113 kg ha -1 . This increase in fruit production and weight in response to higher fertigation levels can be attributed to enhanced photosynthetic activities, increased protein synthesis, and improved photosynthate translocation, as indicated by Maragal et al (2018).…”

Pruning and level of nitrogen influence the growth and yield of bitter gourd. A field experiment was conducted to assess the effect of different pruning and nitrogen levels on the growth and productivity of bitter gourd from March to July 2022 in Nawalparasi East, Nepal. The field experiment was laid out in a split-plot design with three replications. The treatment comprised three levels of pruning (No pruning, second generation (2G) pruning, and third generation (3G) pruning) in main plots and three different doses of nitrogen (100, 150, and 200 kg ha-1) in sub-plots. Observations on growth, floral, and yield parameters were recorded, analyzed, and presented. The research result revealed that 3G pruning with 200 kg ha-1 nitrogen level produced the highest fruit yield (16242.56 kg ha-1) at the fourth harvest. The yield trend showed higher fruit yield at higher nitrogen levels and 3G pruning at all dates of harvest. The increased fruit yield at higher nitrogen levels was because of more number of fruits per plant as well as longer fruit length and larger fruit diameter. The higher productivity in 3G pruning was mainly due to more fruit per plant at the fourth harvest. The results indicate a higher yield of bitter gourd at a higher level of nitrogen with 3G pruning.

The biotic and abiotic stresses cause a significant decline in the yield and fruit quality traits, including antioxidants and minerals, of bitter gourd when grown in open fields. Protected cultivation technology has emerged to minimize such stresses. We investigated the effect of diverse environments (hi-tech greenhouse, naturally ventilated polyhouse, insect-proof net-house, and open field) and breeding lines on earliness, yield potential, antioxidant activities, and dietary nutrients. In the GYT analysis, 12 treatment combinations involving four growing environments and three breeding lines of bitter gourd were examined. The 3-year study suggested that the cultivation of bitter gourd crops in an insect-proof net house (NH) showed superior performance in earliness, yield-attributing traits, antioxidant activities, and dietary nutrients, followed by a naturally ventilated polyhouse (NP). However, NH was on par with NP and significantly better than the open-field-grown crop. The GYT biplot analysis highlighted that the combinations of NH and Pusa Rasdar outperformed and were the most stable treatments for all the traits investigated, followed by NH in conjunction with S32 and S57 lines. This study suggests that growing bitter gourd in protected environments is the optimal strategy to achieve early market prices and improve the yield and nutritional quality of the fruits.

Influence of spacing and pruning on growth, yield and economics of off-season long melon (Cucumis melo)

et al. 2022

Long melon [Cucumis melo var. utilissimus (Roxb.) Duthie & Fuller] cultivation in open field condition in northern India is hampered due to extremes of the temperature from September to January. Therefore, the present study was carried out to explore possibility for off-season production of long melon under protected conditions at Center for Protected Cultivation Technology (CPCT), ICAR-IARI, New Delhi in 2016â€“17 and 2017â€“18. Seedlings were transplanted as per five different spacing and branch pruning methods. The combination of closer spacing with maximum branch node pruning method under polyhouse structure was found better for off-season long melon production. Flowering appeared earlier by 4.02 days, first fruit picking by 5 days, additional number of pickings (5 times) and harvesting period extended by 60 days in polyhouse compared to insect proof net-house structure. The closer spacing S1 (50 cm Ã— 20 cm) exhibited maximum weight of fruits, fruit yield, gross income as well as net-income and B: C ratio. Among pruning methods, complete branch pruning method P1 (single stem cultivation or branch less cultivation) contributed positively significant effect on all parameters of long melon. The combination of polyhouse structure with closer spacing (50 cm Ã— 20 cm) and optimum branch pruning (after one node cutting) gave highest yield and net income per unit area for off-season cultivation of long melon.
