Fruit Drop Control Studies on Coconut at Eastern Terai Conditions of Nepal / Chaudhary, D.K. ; Karki, P. ; P. Bhattarai    

Public ISBD in Fourth national workshop on horticulture , March 2-4, 2004 ; Abstracts     Title : Fruit Drop Control Studies on Coconut at Eastern Terai Conditions of Nepal Material Type: printed text Authors: Chaudhary, D.K., Author ; Karki, P., Author ; P. Bhattarai, Author Pagination: 55-58 p. Languages : English (eng) Keywords: coconut,  cost  benefit  analysis,  fruit  drop,  nutrients, Abstract: A field experimellt was conducted during 1999-2002 (jour years) at RARS, Tarahara with an objective to minimize the immature fruit dropping and reduce the economic losses in coconut. The experiment was laid out in a randomized complete block design with eight treatments in three replications. Number of marketable fruits per tree (fruit yield) gave significant result each year. The trees supplied with Chemical fertilizer @ DAP 2.5 kg + MOP 2kg Urea 1.0kg +lime 500g + Borex 150g +Multiplex 250g + Common salt 500g FYM + 30kg per tree per year produced the highest number of marketabie fruits ( 119) whereas control treatment produced average 38 marketable fruits per tree per year.

A review on management of fruit drop in mango and citrus / Gautam, I.P.    

Public ISBD in Agricultural research for enhancing livelihood of Nepalese people: Proceedings of 2nd SAS-N Convention, 30 July-1 Aug 2003, Kathmandu / Joshi, Bal K.     Title : A review on management of fruit drop in mango and citrus Material Type: printed text Authors: Gautam, I.P., Author Pagination: 28-32 p. Languages : English (eng) Keywords: Citrus,  fruit  drop,  management,  mango Abstract: Mongo and Citrus are important fruits in Nepal. They occupied about 9% and 25% of total fruit cultivated areas respectively in Nepal. However, the notional productivity of mango (7.0 t/ha) and citrus (10.38 t/ha) is very low. Besides other factors, fruit drop is a serious cause of low productivity in both fruit crops. In nature, fruit drop of mango and citrus hove been found very high accounting 99% and 93.52-96.63% respectively. Considering these facts, a number of studies in fruit drop, fruit development stages and their control measures have been reviewed to attract the attention of large number of workers and extension agents for minimizing the fruit drop problem in mango and citrus. The results of the investigations showed that fruit drop is a complex  problem  involving several factors. Application of recommended dose of fertilizers with spraying 2% urea or 4% calcium nitrate containing 50 mg boric acid/lit water reduced fruit drop. Among the various growth regulators, application of NAA and 2,4-D (10-20 ppm) in mango during April to May found effective for retention of fruits in North India condition. Similarly, in citrus 2,4-D ( 10-20 ppm), 2,4,5-T and GA were found effective for controlling fruit drop. The application IAA and NAA were found ineffective due to increase the abscission zone of the fruit.

Life Cycle and Behavior of Citrus Green Stink Bug, Rhynchocoris Lmmeralis Thunberg / Manandhar, R. ; Joshi, S.L. ; Sharma, P. N.    

Public ISBD in Fourth national workshop on horticulture , March 2-4, 2004 ; Abstracts     Title : Life Cycle and Behavior of Citrus Green Stink Bug, Rhynchocoris Lmmeralis Thunberg Material Type: printed text Authors: Manandhar, R., Author ; Joshi, S.L., Author ; Sharma, P. N., Author Pagination: 50-54 p. Languages : English (eng) Keywords: citrus  green  stink  bug,  fruit  drop,  life  cycle,  mandarin  orange Abstract: Rhynchocoris Jwmeralis Thunberg (Citrus green stink bug: CGSB) is one of the important insect pests of mandarin in the westem hills of Nepal, that causes premature fruit drop in mandarin, resulting heavy loss in fruit yield. This study aims to manage it through integrated approach, which comprises of its field life cycle and behavior. This study was carried at Hemja (1060 mas 1.) and Lrmrfe (1675 mas l.) during June to December 2001 and 2002. Freshly hatched nymphs were inoculated in sleeve cage that was confined to a branch having 2-3 small fruits. Observations were made to record incubation period of egg, duration of each nymphal instar and number of dropped fruits at each instar. This study revealed that the pest had five nymphal stages prior to emerge as an adult. The first instar stmted feeding on the fruit that induced fruit drop. The adult of CGSB remained alive for more than 50 days in the winter to build population for the next season.
