The method for study is completely randomized block design with three replications and four treatments such as transparent plastic, black plastic, barley straw and control (without mulch). According to the study, the control treatment, black plastic mulches were a significant effect on the number of weeds and yield of tomatoes. The maximum yields were 48.05 (ton/ha) in black plastic and the minimum yields were 19 (ton/ha) in control mulch. The present work suggests that the application of different types of mulches can be an effective method to reduce the number of weeds in a tomato farm. The black plastic mulch is recommended due to increase in the yield of tomato and also an effective practice on controlling the weeds.</p> Zabihullah Rahmani, Shah Mahmoud Faqiri, Ahmad Jawid Muradi ##submission.copyrightStatement## Thu, 11 Mar 2021 06:42:15 +0000 Mitigating Natural Heat Stress for Tomato (Solanum lycopersicum L) Production through Management Techniques <p>An experiment was conducted to identify suitable production management techniques for tomato (<em>Solanum lycopersicum</em> L.) cultivation during late winter-pre monsoon season in plains of Nepal. For this, organic mulches (rice straw, dried grass, and rice husk) were compared with SN (shade net) and no-mulch (bare field) condition for tomato yield in 2018 and 2019. The pooled analysis of all observed morphological and yield traits were performed and they differed significantly. Rice husk significantly affected number of fruits per inflorescence though number of inflorescence per plant and flowers per inflorescence were similar among organic mulches. The highest fruit yield per plant (4.44 kg plant<sup>-1</sup>) was obtained with rice husk, the other mulches and SN were at par but the lowest yield (2.75 kg plant<sup>-1</sup>) was obtained with no-mulch. Similarly, rice husk mulch contributed to the highest number of fruits per inflorescence (5.22), highest fruit weight (46.58 g) and diameter (4.99 cm).Fruit yield positively and significantly associated with fruit per inflorescence(0.78***), fruit diameter (0.65***) and an average fruit weight (0.56***).Organic mulches significantly (<em>p</em>=0.05) contributed to higher yield (86.01 t ha<sup>-1</sup>) over SN (76.55 t ha<sup>-1</sup>).Higher values for total soluble solid, Vitamin C and fruit firmness were observed under rice husk mulching. The result of the present study found rice husk mulching as better option for tomato production as compared to SN and no-mulch condition.</p> Tika Ram Chapagain, Arjun Kumar Shrestha, Moha Dutta Sharma, Kalyani Mishra Tripathi, Aravind Srivastava ##submission.copyrightStatement## Wed, 24 Mar 2021 00:00:00 +0000 Effect of Different Doses and Sources of Nitrogen on Postharvest Quality of Cauliflower <p>In Nepal, there is lacking of proper nitrogen management regarding postharvest quality of cauliflower in the Terai region of Nepal. In order to address these problems, a field experiment was conducted in a split-plot design to determine the appropriate dose of nitrogen and combined effect of urea and poultry manure for better postharvest quality of cauliflower in Rampur, Chitwan. The study was carried out in nine treatment combinations from two different factors, with four replications in a late season variety, Bishop from November 2017 to March 2018. The plots consisted of three treatments of 260, 200, and 140 kg N/ha, while the sub-plots were 100 % N from urea; 50% N from urea and 50% N from poultry manure; and 100% N from poultry manure. Significantly higher vitamin C content of 52.4 mg/100 g was found in 140 kg N/ha than other treatments. Similarly, higher TSS content of 6.3°Brix was found in 260 kg N/ha. More compact and acceptable curds were produced in 260 kg N/ha. Similarly, higher vitamin C content of 52.0 mg/100 g and higher TSS content of 6.0°Brix was produced by 50% N from urea plus 50% N from poultry manure. Significantly more tastier and compact curds were produced by 100% N from poultry manure along with 50% N from urea and 50% N from poultry manure. Higher physiological weight (30.3%) was found in 260 kg N/ha while lower physiological weight loss (24.4%) was found in 50% N from urea and 50% N from poultry manure. From this study, it was concluded that 200 kg nitrogen combination with poultry manure instead of inorganic fertilizer can improve the postharvest quality of cauliflower in Terai region of Nepal.</p> Hom Nath Giri ##submission.copyrightStatement## Sat, 03 Apr 2021 00:00:00 +0000 Impact of Bi-Parental Mating on Character Association in Barley (Hordeum vulgare L.) <p>Correlation between grain yield and contributing characters in 100 biparental progenies (BIPs) developed from a barley cross RD-2035 x RD-2552 and corresponding F<sub>3 </sub>progenies were compared. The correlation coefficients in BIPs were found generally of higher magnitude than F<sub>3</sub> progenies. Even, non-significant negative association in F3 between grain yield per plant and harvest index converted into significant and positive in BIP progenies. Higher degree of positive and significant correlation was observed in tillers per plant, spikelets per spike and grain per spike with grain yield per plant in BIPs as well as F<sub>3</sub> population.</p> Ved Prakash, S.
