The study aimed to estimate the level of yield gaps maize in major producing areas, point out causes farmers’ fields, and identify opportunities existing through management practices production Central Java. This is strategy for closing achieve food self-sufficiency agricultural land. Methods estimates should cover data sources on physical conditions (weather soil), practices, smallholder shape...

One of the crucial issues in developing nations is diminishing yield gaps. Therefore, accurate gap estimation has many real-world uses for increasing crop production. Utilizing comparative performance analysis (CPA) techniques, wheat fields was evaluated this study. In Varamin, Tehran Province, Iran, data on 104 were collected between 2018 and 2020 every aspect field management been documented....

In this paper we study the gap between the logarithm of the rank of a matrix and its communication complexity. The main contribution of the paper relies on the algebraic interpretation of some methods which yield non constant gaps by combining, mainly via tensor products, matrices with constant gap.
