New Superior Variety Adaptation and Number of Breeds on Productivity Lowland Rice

Abstract

This study aims to obtain new adaptive superior varieties, obtain the appropriate number of seeds and produce a combination of technological packages between varieties and the number of suitable seeds to increase productivity lowland rice. The design used was factorial Randomized Block Design (RBD) consisting of 2 factors, namely the first factor of the variety consisted of Ciherang, Inpari 30 and Inpara 2. The second factor was the use of the number of seeds consisting of 2 stems, 5 stems, 8 stems, and 11 stems. The second combination was 12 treatments, which were repeated 3 times, overall there were 36 trial plots. The results showed that the productivity of Inpara 2 varieties of rice gave an increase in yield of 36.82% harvested dry grain compared to the Ciherang variety which is an existing variety. The use of 2-11 stems is not significant for plant productivity, but only affects the amount of filled grain and the number of grains per panicle, in the treatment of the number of seeds of 8 stems. Inpari 30 varieties with 2 and 5 stems have the highest 1000 grains of 25.89 and 25.81 g, respectively.

Growth and production of upland rice (Oryza sativa L.) in ultisol using liquid organic fertilizer and NPK

“…The interaction of LOF with NPK fertilizers as well as the main factors of LOF and the NPK fertilizers had no significant effect on the weight of 1,000 rice grains (Table 8). According to Sution and Serom (2019) stated that genetics and environment influence seed size. Kaihatu and Pesireron (2011) added that other factors, such as competition between seeds in rice plants, can affect seed size.…”
